INTRODUCTORY NOTE

Unless the context otherwise requires, in this Annual Report on Form 10-K (“Annual Report”), “we”, “us”, “our” and the “Company” mean ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH.

Forward-Looking Statements

We believe that it is important to communicate our future expectations to our shareholders and to the public. This Annual Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, without limitation, statements about our future plans, objectives, and expectations under the headings “Item 1. Business” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements include any statement that does not directly relate to any historical or current fact. When used in this Annual Report and in future filings by the Company with the Securities and Exchange Commission (“SEC”), the words or phrases “will likely result”, “management expects”, “we expect”, “will continue”, “is anticipated”, “estimated” or similar expressions are intended to identify such “forward-looking statements.” Readers are cautioned not to place undue reliance on such forward-looking statements, each of which speaks only as of the date made. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results and those presently anticipated or projected, including the risks and uncertainties set forth in this Annual Report under the heading “Item 1A. Risk Factors” and in our other periodic reports. Examples of such risks and uncertainties include general economic and business conditions, the outcome of litigation, unexpected changes in technologies and technological advances, reliance on our intellectual property, and the ability to obtain adequate financing in the future. We have no obligation to publicly release the results of any revisions that may be made to any forward-looking statements to reflect anticipated events or circumstances occurring after the date of such statements.

PART I

Item 1. Business.

We are in the business of innovating fundamental wireless technologies and products. We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits for use in wireless communication products.

We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America (“U.S.”) and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore the primary focus of our current business plan is the enforcement of our intellectual property rights through licensing efforts and patent infringement litigation.

We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor suppliers for the infringement of several of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization.

We spent the majority of 2022 supporting our current patent enforcement actions.  Beginning in 2020, we filed several patent enforcement cases in the Western District of Texas and, through 2022, we had entered into three patent license and settlement agreements with defendants, resulting in the dismissal of four pending actions.  In February 2023, we entered into another patent license and settlement agreement and dismissed two additional actions.  We currently have five enforcement actions pending in Texas against four separate foreign defendants.

Additionally, we had two patent enforcement cases pending against Qualcomm in the Middle District of Florida.  In March 2022, the district court in one of those cases granted Qualcomm's motion for summary judgment ruling that Qualcomm does not infringe the three patents in the case.  We have an appeal pending at the Federal Circuit which is expected to be decided in 2023.  The second case which is pending against Qualcomm and Apple has been stayed pending the outcome of the first case. We also have a patent enforcement action against LG in the District of New Jersey that is stayed pending resolution of the Qualcomm and Apple case in Florida.  See “Legal Proceedings” in Note 13 to our consolidated financial statements included in Item 8 for a detailed description of our various patent enforcement actions.

A significant portion of our litigation costs have been funded under a secured contingent payment arrangement with Brickell Key Investments, LP (“Brickell”), contingent arrangements with legal counsel, and various debt and equity financings. See “Liquidity and Capital Resources” included in Item 7 for a full discussion of our litigation funding arrangements and our equity and debt financings.

Products and Licenses

Since 2019, we have not offered any products for sale, but rather focused exclusively on our patent enforcement and licensing efforts. As of December 31, 2022, we had four licensees for our technologies, including one licensee added in 2022.  All of our license agreements resulted from settlement of patent enforcement actions initiated by us.  Our patent license and settlement agreements typically include a one-time, up-front payment to cover past and future use of our technologies, with no future recurring revenue.  See “Revenue” in Note 3 to our consolidated financial statements included in Item 8 for additional details.

RF Technologies

Our RF technologies enable highly accurate transmission and reception of RF carriers at low power consumption, thereby enabling extended battery life, and certain size, cost, performance, and packaging advantages.  We believe the most significant hurdle to the licensing and/or sale of our technologies and related products is the widespread use of certain of our technologies in infringing products produced by companies with significantly greater financial, technical, sales, and marketing resources. We believe we can secure licensing agreements with unauthorized current users of one or more of our technologies based on a solid and defensible patent portfolio and the advantages enabled by our unique patent-protected technologies.

Patents and Trademarks

We consider our intellectual property, including patents, patent applications, trademarks, and trade secrets to be significant to our business plan. We have a program to file applications for and obtain patents, copyrights, and trademarks in the U.S. and in selected foreign countries where we believe filing for such protection is appropriate to establish and maintain our proprietary rights in our technology and products.  As of December 31, 2022, we had approximately 60 active U.S. and foreign patents related to our RF technologies.  In addition, we have a number of recently expired patents that we believe continue to have significant economic value as a result of our ability to assert past damages in our patent enforcement actions.  We estimate the economic lives of our patents to be the shorter of fifteen years from issuance or twenty years from the earliest application date.  Our current portfolio of issued patents have expirations ranging from 2023 to 2036.

Employees

As of December 31, 2022, we had seven full-time employees and one part-time employee.  We also outsource certain specialty services, such as information technology and public relations, and utilize contract staff and third-party consultants from time to time to supplement our workforce.  Our employees are not represented by any collective bargaining agreements and we consider our employee relations to be satisfactory.

Following the COVID-19 pandemic, we have reverted to fully remote worksites for all of our employees.  Our management, with the oversight of our board of directors, monitors the hiring, retention, and management of our employees.

Available Information and Access to Reports

We file annual reports on Forms 10-K, quarterly reports on Forms 10-Q, proxy statements and other reports, including any amendments thereto, electronically with the SEC. The SEC maintains an Internet site (http://www.sec.gov) where these reports may be obtained at no charge.  We also make copies of these reports available, free of charge through our website (http://www.parkervision.com) via the link “SEC filings” as soon as practicable after filing or furnishing such materials with the SEC.

Corporate Website

We announce investor information, including news and commentary about our business, financial performance and related matters, SEC filings, notices of investor events, and our press and earnings releases, in the investor relations section of our website (http://ir.parkervision.com).  Additionally, if applicable, we webcast our earnings calls and certain events we participate in or host with members of the investment community in the investor relations section of our website. Investors and others can receive notifications of new information posted in the investor relations section in real time by signing up for email alerts and/or RSS feeds.  Further corporate governance information, including our governance guidelines, Board committee charters, and code of conduct, is also available in the investor relations section of our website under the heading “Corporate Governance.”  The content of our website is not incorporated by reference into this Annual Report or in any other report or document we file with the SEC, and any references to our website are intended to be inactive textual references only.

Item 1A. Risk Factors.

In addition to other risks and uncertainties described in this Annual Report, the following risk factors should be carefully considered in evaluating our business because such factors may have a significant impact on our business, operating results, liquidity and financial condition. As a result of the risk factors set forth below, actual results could differ materially from those projected in any forward-looking statements.

Financial and Operating Risks

Our financial condition raises substantial doubt as to our ability to continue as a going concern.

We have had significant losses and negative cash flows in every year since inception, and continue to have an accumulated deficit which, at December 31, 2022, was approximately $443.2 million.  Our net losses for the years ended December 31, 2022 and 2021 were approximately $9.8 million and $12.3 million, respectively.  Our independent registered public accounting firm has included in their audit opinion on our consolidated financial statements as of and for the year ended December 31, 2022, a statement with respect to substantial doubt about our ability to continue as a going concern. Note 2 to our consolidated financial statements included in Item 8 includes a discussion regarding our liquidity and our ability to continue as a going concern.  Our consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.  If we become unable to continue as a going concern, we may have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements.  The substantial doubt as to our ability to continue as a going concern may adversely affect our ability to negotiate reasonable terms with our vendors and may adversely affect our ability to raise additional capital in the future.

We have had a history of losses which may ultimately compromise our ability to implement our business plan and continue in operation.

Through December 31, 2022, our technologies and products have not produced revenues sufficient to cover our operating costs.  We will continue to make expenditures on patent protection and enforcement and general operations in order to continue our current patent enforcement and licensing efforts.  Although we expect sufficient revenues from patent licensing and settlement agreements to cover our operating costs and achieve profitability in 2023, required repayments of contingent expenses and debt obligations will result in insufficient capital resources for sustainment of our operations through 2023.  If we are not able to generate sufficient capital resources, we may not be able to implement our business plan or meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements and investors will suffer a loss in their investment.  This may also result in a change in our business strategies.

We will need to raise substantial additional capital in the future to fund our operations. Failure to raise such additional capital may prevent us from implementing our business plan as currently formulated.

Because we have had net losses and, to date, have not generated positive cash flow from operations, we have funded our operating losses primarily from the sale of debt and equity securities, including our secured and unsecured contingent debt obligations. Our current capital resources include cash and cash equivalents of $0.1 million at December 31, 2022, and $0.8 million in proceeds from debt and equity financings in January 2023.  Our business plan will continue to require expenditures for patent protection and enforcement and general operations.  For the years ended December 31, 2022 and 2021, we used $3.0 million and $7.7 million, respectively in cash for operations which was funded primarily through the sale of convertible debt and equity securities.  Our current capital resources will not be sufficient to meet our working capital needs for the twelve months after the issuance of our consolidated financial statements and we will require additional capital to fund our operations.  Additional capital may be in the form of debt securities, the sale of equity securities, including common or preferred stock, additional litigation funding, or a combination thereof.  Failure to raise additional capital may have a material adverse impact on our ability to achieve our business objectives.

Table of Contents

Raising additional capital by issuing debt securities or additional equity securities may result in dilution and/or impose covenants or restrictions that create operational limitations or other obligations.  

We will require additional capital to fund our operations and meet our current obligations due within the twelve months after the issuance date of our consolidated financial statements. Financing, if any, may be in the form of debt or sales of equity securities, including common or preferred stock.  Debt instruments or the sale of preferred stock may result in the imposition of operational limitations and other covenants and payment obligations, any of which may be burdensome to us and may have a material adverse impact on our ability to implement our business plan as currently formulated.  The sale of equity securities, including common or preferred stock, may result in dilution to the current stockholders’ ownership and may be limited by the number of shares we have authorized and available for issuance.

We may be obligated to repay outstanding notes at a premium upon the occurrence of an event of default.

We have $4.5 million in outstanding principal under convertible notes at December 31, 2022.  If we fail to comply with the various covenants set forth in each of the notes, including failure to pay principal or interest when due or, under certain notes, consummating a change in control, we could be in default thereunder.  Upon an event of default under each of the notes, the interest rate of the notes will increase to 12% per annum and the outstanding principal balance of the notes plus all accrued unpaid interest may be declared immediately payable by the holders.  We may not have sufficient available funds to repay the notes upon an event of default, and we cannot provide assurances that we will be able to obtain other financing at terms acceptable to us, or at all.

Our ability to utilize our tax benefits could be substantially limited if we fail to generate sufficient income or if we experience an “ownership change.”

We have cumulative net operating loss carryforwards (“NOLs”) totaling approximately $300.8 million at December 31, 2022, of which $260.1 million is subject to expiration in varying amounts from 2023 to 2037.  Our ability to fully recognize the benefits from those NOLs is dependent upon our ability to generate sufficient income prior to their expiration.  In addition, our NOL carryforwards may be limited if we experience an ownership change as defined by Section 382 of the Internal Revenue Code (“Section 382”).  In general, an ownership change under Section 382 occurs if one or more 5% shareholders increase their collective ownership of the aggregate amount of our outstanding shares by more than 50 percentage points over a relevant lookback period.  We have sold a significant number of equity securities over the relevant lookback period which increases the risk of triggering an ownership change under Section 382 from the future sale of additional equity securities.  An ownership change under Section 382 will significantly limit our ability to utilize our tax benefits.

Our litigation funding arrangements may impair our ability to obtain future financing and/or generate sufficient cash flows to support our future operations.

We have funded much of our cost of litigation through contingent financing arrangements with Brickell Key Investments LP (“Brickell”) and others and contingent fee arrangements with legal counsel.  The repayment obligation to Brickell is secured by the majority of our assets until such time that we have repaid a specified minimum return.  Furthermore, our contingent arrangements will result in reductions in the amount of net proceeds retained by us from litigation, licensing, and other patent-related activities.  The contingent fees payable to legal counsel, Brickell and others will consume all of our initial future proceeds up to specified limits and could exceed half of our proceeds thereafter depending on size and timing of proceeds, among other factors.  The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent related proceeds sufficient to offset expenses and meet our contingent payment obligations.  Failure to generate revenue or other patent-related proceeds sufficient to repay our contingent obligations may impede our ability to obtain additional financing which will have a material adverse effect on our ability to achieve our long-term business objectives.

Table of Contents

Our litigation can be time-consuming, costly and we cannot anticipate the results.

Since 2011, we have spent a significant amount of our financial and management resources to pursue patent infringement litigation against third parties.  We believe this litigation, and other litigation matters that we may in the future determine to pursue, will continue to consume management and financial resources for long periods of time.  There can be no assurance that our current or future litigation matters will ultimately result in a favorable outcome for us or that our financial resources will not be exhausted before achieving a favorable outcome.  In addition, even if we obtain favorable interim rulings or verdicts in particular litigation matters, they may not be predictive of the ultimate resolution of the matter.  Unfavorable outcomes could result in exhaustion of our financial resources and could hinder our ability to pursue licensing and/or product opportunities for our technologies in the future.  Failure to achieve favorable outcomes from one or more of our patent enforcement actions will have a material adverse impact on our financial condition, results of operations, cash flows, and business prospects.

If our patents and intellectual property rights do not provide us with the anticipated market protections, our competitive position, business, and prospects will be impaired.

We rely on our intellectual property rights, including patents and patent applications, to provide competitive advantage and protect us from theft of our intellectual property.  We believe that our patents are for entirely new technologies and that our patents are valid, enforceable, and valuable.  However, third parties have made claims of invalidity with respect to certain of our patents and other similar claims may be brought in the future.  For example, the Patent Trial and Appeal Board has issued a number of rulings invalidating challenged claims of certain of our patents as a result of third-party challenges filed by defendants in our patent enforcement actions.  If our patents are shown not to be as broad as currently believed or are otherwise challenged such that some or all of the protection is lost, we will suffer adverse effects from the loss of competitive advantage and our ability to offer unique products and technologies.  As a result, there would be an adverse impact on our financial condition and business prospects.  Furthermore, defending against challenges to our patents may give rise to material costs for defense and divert resources away from our other activities.

Our business, results of operations, and financial condition may be impacted by the ongoing coronavirus (COVID-19) outbreaks.

The global spread of COVID-19 created significant volatility and uncertainty in financial markets.  If such volatility and uncertainty persist, we may be unable to raise additional capital on terms that are acceptable to us, or at all.  Additionally, in response to the pandemic, governments and the private sector have taken a number of drastic measures to contain the spread of COVID-19.  While our employees currently have the ability and are encouraged to work remotely, such measures may have a substantial impact on employee attendance or productivity, which, along with the possibility of employees’ illness, may adversely affect our operations.

In addition, COVID-19 has negatively impacted the timing of our current patent infringement actions as a result of office closures, travel restrictions and court closures.  For example, our patent infringement trial in Orlando, Florida was delayed twice due to the impact of COVID-19.  It is possible that further delays in our cases could occur.

Although COVID-19 is currently not material to our results of operations, there is significant uncertainty relating to the potential impact of COVID-19 on our business.  The extent to which COVID-19 impacts our ongoing patent enforcement actions and our ability to obtain financing, as well as our results of operations and financial condition, generally, will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions taken by governments and private businesses to contain COVID-19 or treat its impact, among others.  If the disruptions posed by COVID-19 continue for an extensive period of time, our business, results of operations, and financial condition may be materially adversely affected.

Table of Contents

We are subject to outside influences beyond our control, including new legislation that could adversely affect our licensing and enforcement activities and have an adverse impact on the execution of our business plan.

Our licensing and enforcement activities are subject to numerous risks from outside influences, including new legislation, regulations and rules related to obtaining or enforcing patents.  For instance, the U.S. has enacted sweeping changes to the U.S. patent system including changes that transition the U.S. from a “first-to-invent” to a “first-to-file” system and other changes that alter the processes for challenging issued patents.  To the extent that we are unable to secure patent protection for our future technologies and/or our current patents are challenged such that some or all of our protection is lost, we will suffer adverse effects to our ability to offer unique products and technologies.  As a result, there would be an adverse impact on our financial position, results of operations and cash flows and our ability to execute our business plan.

Our industry is subject to rapid technological changes which if we are unable to match or surpass, will result in a loss of competitive advantage and market opportunity.

Because of the rapid technological development that regularly occurs in the wireless technology industry, along with shifting user needs and the introduction of competing products and services, we have historically devoted substantial resources to developing and improving our technology and introducing new product offerings.  As a result of our limited financial resources, we have ceased our research and development activities which could result in a loss of future market opportunity which could adversely affect our future revenue potential.

We are highly dependent on Mr. Jeffrey Parker as our chief executive officer.  If his services were lost, it would have an adverse impact on the execution of our business plan.

Because of Mr. Parker’s leadership position in the Company, the relationships he has garnered in both the industry in which we operate and the investment community and the key role he plays in our patent litigation strategies, the loss of his services might be seen as an impediment to the execution of our business plan.  If Mr. Parker was no longer available to the Company, investors might experience an adverse impact on their investment. 

If we are unable to retain key highly skilled employees, we will not be able to execute our current business plans.

Our business is dependent on having skilled and specialized key employees to conduct our business activities.  The inability to retain these key employees would have an adverse impact on the technical support activities and the financial reporting and regulatory compliance activities that our business requires.  These activities are instrumental to the successful execution of our business plan.

Any disruptions to our information technology systems or breaches of our network security could interrupt our operations, compromise our reputation, and expose us to litigation, government enforcement actions, and costly response measures and could have a material adverse effect on our business, financial condition, and results of operations.

We rely on information technology systems, including third-party hosted servers and cloud-based servers, to keep business, financial, and corporate records, communicate internally and externally, and operate other critical functions.  If any of our internal systems or the systems of our third-party providers are compromised due to computer virus, unauthorized access, malware, and the like, then sensitive documents could be exposed or deleted, and our ability to conduct business could be impaired. Cyber incidents can result from deliberate attacks or unintentional events.  These incidents can include, but are not limited to, unauthorized access to our systems, computer viruses or other malicious code, denial of service attacks, malware, ransomware, phishing, SQL injection attacks, human error, or other events that result in security breaches or give rise to the manipulation or loss of sensitive information or assets.  Cyber incidents can be caused by various persons or groups, including disgruntled employees and vendors, activists, organized crime groups, and state-sponsored and individual hackers.  Cyber incidents can also be caused or aggravated by natural events, such as earthquakes, floods, fires, power loss, and telecommunications failures.  The risk of cybersecurity breach has generally increased as the number, intensity, and sophistication of attempted attacks from around the world has increased.  While we have cyber security procedures in place, given the evolving nature of these threats, there can be no assurance that we will not suffer material losses in the future due to cyber-attacks.

To date, we have not experienced any material losses relating to cyber-attacks, computer viruses or other systems failures.  Although we have taken steps to protect the security of data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning or the improper disclosure of personally identifiable information, such as in the event of cyber-attacks. In addition to operational and business consequences, if our cybersecurity is breached, we could be held liable to our customers or other parties in regulatory or other actions, and we may be exposed to reputation damages and loss of trust and business.  This could result in costly investigations and litigation, civil or criminal penalties, fines, and negative publicity.

Risks Relating to our Common Stock

Our outstanding options and warrants may affect the market price and liquidity of the common stock.

At December 31, 2022, we had 81.2 million shares of common stock outstanding and had outstanding options and warrants for the purchase of up to 34.7 million additional shares of common stock, of which approximately 33.3 million were exercisable as of December 31, 2022.  In addition, as described more fully below, holders of convertible notes may elect to receive up to 32.7 million shares of common stock upon conversion of the notes, and we may elect to pay accrued interest on the notes in shares of our common stock.  All of the shares of common stock underlying these securities are currently registered for sale to the holder or for public resale by the holder.  The amount of common stock reserved for issuance may have an adverse impact on our ability to raise capital and may affect the price and liquidity of our common stock in the public market. In addition, the issuance of these shares of common stock will have a dilutive effect on current stockholders’ ownership.

The conversion of outstanding convertible notes into shares of common stock, and the issuance of common stock by us as payment of accrued interest upon the convertible notes, could materially dilute our current stockholders.

We have an aggregate principal amount of $4.5 million in convertible notes outstanding at December 31, 2022.  The notes are convertible into shares of our common stock at fixed conversion prices, which may be less than the market price of our common stock at the time of conversion.  If the entire principal were converted into shares of common stock, we would be required to issue an aggregate of up to 32.7 million shares of common stock.  In addition, in January 2023 we issued an additional aggregate principal amount of $0.7 million in convertible notes which, if converted at the fixed conversion price, would result in the issuance of an additional 4.4 million shares of our common stock.  If we issue all of these shares, the ownership of our current stockholders will be diluted.

Further, we may elect to pay interest on the notes, at our option, in shares of common stock, at a price equal to the then-market price for our common stock.  As of December 31, 2022, we have issued approximately 3.9 million shares of common stock as in-kind interest payments on our convertible notes.  We currently do not believe that we will have the financial ability to make payments on the notes in cash when due.  Accordingly, we currently intend to make such payments in shares of our common stock to the greatest extent possible.  Such interest payments could further dilute our current stockholders.

The price of our common stock may be subject to substantial volatility.

The trading price of our common stock has been and may continue to be volatile. Between January 1, 2021 and March 1, 2023, the reported high and low sales prices for our common stock ranged between $0.11 and $1.91 per share.  The price of our common stock may continue to be volatile as a result of a number of factors, some of which are beyond our control.  These factors include, but are not limited to, developments in outstanding litigation, our performance and prospects, general conditions of the markets in which we compete, economic and financial conditions, and the impact of COVID-19 on global financial markets.  Such volatility could materially and adversely affect the market price of our common stock in future periods.

Our common stock is quoted on OTCQB, an over-the-counter market.  There can be no assurance that our common stock will continue to trade on the OTCQB or on another over-the-counter market or securities exchange.

Our common stock began trading on the OTCQB, an over-the-counter market, in August 2018 immediately following delisting from Nasdaq, under the symbol “PRKR”.  The over-the-counter market is a significantly more limited market than a nationally-recognized securities exchange such as Nasdaq, and the quotation of our common stock on the over-the-counter market has resulted in a less liquid market available for existing and potential stockholders to trade shares of our common stock.  Securities traded in the over-the-counter market generally have less liquidity due to factors such as the reduced number of investors that will consider investing in the securities, the reduced number of market makers in the securities, and the reduced number of securities analysts that follow such securities.  As a result, holders of shares of our common stock may find it difficult to resell their shares at prices quoted in the market or at all.  We are also subject to additional compliance requirements under applicable state laws relating to the issuance of our securities.  This could have a long-term adverse effect on our ability to raise capital, which ultimately could adversely affect the market price of our common stock.  We cannot provide any assurances as to if or when we will be in a position to relist our common stock on a nationally-recognized securities exchange.

Our common stock is classified as a “penny stock” under SEC rules, which means broker-dealers who make a market in our stock will be subject to additional compliance requirements.

Our common stock is deemed to be a "penny stock" as defined in the Securities Exchange Act of 1934 (the “Exchange Act”).  Penny stocks are stocks (i) with a price of less than five dollars per share; (ii) that are not traded on a recognized national exchange; (iii) whose prices are not quoted on an automated quotation system sponsored by a recognized national securities association; or (iv) whose issuer has net tangible assets less than $2,000,000 (if the issuer has been in continuous operation for at least three years); or $5,000,000 (if continuous operations for less than three years); or with average revenues of less than $6,000,000 for the last three years.  The Exchange Act requires broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document before effecting any transaction in a penny stock for the investor’s account.  Potential investors in our common stock are urged to obtain and read such disclosure carefully before purchasing any shares that are deemed to be “penny stock.”  Further, the Exchange Act requires broker-dealers dealing in penny stocks to approve the account of any investor for transactions in such stocks before selling any penny stock to that investor.  These procedures require the broker-dealer to (i) obtain from the investor information concerning his, her or its financial situation, investment experience and investment objectives; (ii) reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor, and that the investor has sufficient knowledge and experience as to be reasonably capable of evaluating the risks of penny stock transactions; (iii) provide the investor with a written statement setting forth the basis on which the broker dealer made the determination in (ii) above; and (iv) receive a signed and dated copy of such statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives.  Compliance with these requirements may affect the ability or willingness of broker-dealers to sell our securities, and accordingly would affect the ability of stockholders to sell their securities in the public market.  These additional procedures could also limit our ability to raise additional capital in the future.

We do not currently pay dividends on our common stock and thus stockholders must look to appreciation of our common stock to realize a gain on their investments.

We do not currently pay dividends on our common stock and intend to retain our cash and future earnings, if any, to fund our business plan.  Our future dividend policy is within the discretion of our board of directors and will depend upon various factors, including our business, financial condition, results of operations and capital requirements.  We therefore cannot offer any assurance that our board of directors will determine to pay special or regular dividends in the future.  Accordingly, unless our board of directors determines to pay dividends, stockholders will be required to look to appreciation of our common stock to realize a gain on their investment.  There can be no assurance that this appreciation will occur.

Provisions in our certificate of incorporation and by-laws could have effects that conflict with the interest of shareholders.

Some provisions in our certificate of incorporation and by-laws could make it more difficult for a third party to acquire control of us.  For example, our board of directors is divided into three classes with directors having staggered terms of office, our board of directors has the ability to issue preferred stock without shareholder approval, and there are advance notification provisions for director nominations and submissions of proposals from shareholders to a vote by all the shareholders under the by-laws.  Florida law also has anti-takeover provisions in its corporate statute.

Table of Contents

We have a shareholder protection rights plan that may delay or discourage someone from making an offer to purchase the Company without prior consultation with the board of directors and management, which may conflict with the interests of some of the shareholders.

On November 17, 2005, as amended on November 20, 2015 and November 20, 2020, our board of directors adopted a shareholder protection rights plan which called for the issuance, on November 29, 2005, as a dividend, of rights to acquire fractional shares of preferred stock. The rights are attached to the shares of common stock and transfer with them. In the future, the rights may become exchangeable for shares of preferred stock with various provisions that may discourage a takeover bid.  Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of the Company more costly.  The principal objective of the plan is to cause someone interested in acquiring the Company to negotiate with the board of directors rather than launch an unsolicited bid. This plan may limit, prevent, or discourage a takeover offer that some shareholders may find more advantageous than a negotiated transaction.  A negotiated transaction may not be in the best interests of the shareholders.

Item 6. [Reserved].

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Executive Overview

We are in the business of innovating fundamental wireless technologies and products. We have designed and developed proprietary RF technologies and integrated circuits based on those technologies, and we license our technologies to others for use in wireless communication products. We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the U.S. and certain foreign jurisdictions. We believe certain patents protecting our proprietary technologies have been broadly infringed by others and therefore our business plan primarily consists of enforcement of our intellectual property rights through patent licensing efforts and infringement litigation. We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor suppliers for the infringement of a number of our RF patents. We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization.

Table of Contents

We continue to aggressively pursue licensing opportunities with wireless communications companies that make, use or sell semiconductors and/or products that incorporate RF.  We believe there are a number of wireless communications companies that can benefit from the use of the RF technologies we have developed, whether through a license or, in certain cases, a joint product venture that may include licensing rights.  Our licensing efforts to date have required litigation in order to enforce and/or defend our intellectual property rights.  Since 2011, we have been involved in patent infringement litigation against Qualcomm and subsequently others for the unauthorized use of our technology.  Refer to Note 13 to our consolidated financial statements included in Item 8 for a complete discussion of our legal proceedings.  We have expended significant resources since 2011 and incurred significant debt for the enforcement and defense of our intellectual property rights.

Recent Developments

Debt and Equity Financing

In January 2023, we received aggregate proceeds of approximately $0.7 million from the sale of convertible notes to accredited investors.  The notes are convertible, at the holders' option, into shares of our common stock at a fixed conversion price of $0.16 per share and bear interest at a stated rate of 9% per annum.  In addition, in January 2023, we received aggregate proceeds of approximately $0.14 million from the sale of common stock to accredited investors at a price of $0.16 per share.  We entered into registration rights agreements with the investors pursuant to which we will register the shares.  Refer to Note 18 to our consolidated financial statements included in Item 8 for a complete discussion of these financing transactions.

Legal Proceedings

In February 2023, we entered into a confidential patent license and settlement agreement and in March 2023, we received a payment of $25 million with respect thereto.

In February 2023, we dismissed our two patent enforcement actions against Intel Corporation.

Refer to Note 13 to our consolidated financial statements included in Item 8 for a complete discussion of our patent enforcement proceedings.

Liquidity and Capital Resources

We have incurred significant losses from operations and negative cash flows in every year since inception, largely as a result of our significant investments in developing advanced technologies and protecting our intellectual property.  We have utilized the proceeds from sales of debt and equity securities and contingent funding arrangements with third parties to fund our operations, including the cost of litigation to enforce our intellectual property rights.

For the year ended December 31, 2022, we incurred a net loss of approximately $9.8 million and negative cash flows from operations of approximately $3.0 million.  At December 31, 2022, we had cash and cash equivalents of approximately $0.1 million and an accumulated deficit of approximately $443.2 million.  Additionally, a significant amount of future proceeds that we may receive from our patent enforcement and licensing programs will first be utilized to repay borrowings, legal fees, and litigation expenses under our contingent funding arrangements.  Our independent registered public accounting firm has included in their audit report an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. See Note 2 to our consolidated financial statements included in Item 8 for a discussion of our liquidity and our ability to continue as a going concern.

We used cash for operations of approximately $3.0 million and $7.7 million for the years ended December 31, 2022 and 2021, respectively. The decrease in cash used for operations from 2021 to 2022 is primarily due to the use of approximately $3.9 million in cash for the reduction of accounts payable and accrued expenses during the year ended December 31, 2021, as compared to a $0.4 million increase in accounts payable and accrued expenses during the year ended December 31, 2022.  The reduction in accounts payable during the year ended December 31, 2021 is primarily the result of a $3.0 million payment to a law firm in settlement of our outstanding fees and expenses and in exchange for an agreed-upon reduction in potential success fees payable to the firm from future patent-related proceeds.

For the year ended December 31, 2022, we received aggregate net proceeds from the sale of debt and equity securities, including the exercise of outstanding options and warrants, of approximately $2.1 million compared to approximately $7.2 million in proceeds received for the year ended December 31, 2021.  We repaid approximately $0.1 million in debt obligations during each of the years ended December 31, 2022 and 2021.

Significant portions of our litigation costs to date have been funded by contingent payment arrangements with legal counsel.  Fee discounts offered by legal counsel in exchange for contingent payments upon successful outcome in our litigation are not recognized in expense until such time that the related proceeds on which the contingent fees are payable are considered probable.  Contingent fees vary based on each firm’s specific fee agreement.  We currently have contingent fee arrangements in place for all of our active cases. In addition to our contingent fee agreements with legal counsel, we have secured and unsecured contingent payment obligations to litigation funders that have priority payments due from patent-related proceeds as discussed more fully under “Financial Condition - Contingent Payment Obligations” below.

In March 2023, we received $25.0 million in proceeds from a patent license and settlement agreement.  These proceeds are expected to be used entirely for the payment of contingent legal fees and expenses and the repayment of principal on our secured contingent debt obligation and therefore our ability to meet our short-term liquidity needs is dependent upon one or more of (i) our ability to successfully negotiate future licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations to Brickell and legal counsel; and/or (ii) our ability to raise additional capital from the sale of debt or equity securities or other financing arrangements.  We are currently in discussions with Brickell regarding restructuring of our contingent payment obligation, including additional new funds.  There can be no assurance that a favorable restructuring of our Brickell obligation will be achieved at all, or in a manner that provides significant future benefit to us.

Based on our current outstanding legal proceedings, funding arrangements and contingent payment arrangements, we estimate that up to 100% of our initial future proceeds will be used to repay contingent payment arrangements at least until the outstanding principal under our secured contingent payment obligation has been repaid.  After repayment of principal, we estimate that approximately 75% of future proceeds could be payable to others until such time that minimum returns have been achieved, depending on the proceeding and the nature, amount and timing of proceeds, among other factors.

Table of Contents

Patent enforcement litigation is costly and time-consuming, and the outcome is difficult to predict.  We expect to continue to invest in the support of our patent enforcement and licensing programs.  We expect that cash flows generated from proceeds received from patent enforcement actions and/or technology licenses in 2023, after deduction of contingent payment obligations, may not be sufficient to cover our operating expenses.  In the event we do not generate revenues, or other patent-related proceeds, sufficient to cover our operational costs and contingent repayment obligations, we will be required to raise additional working capital through the sale of debt or equity securities or other financing arrangements.

The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent-related proceeds sufficient to offset expenses and meet our contingent payment obligations and other long-term debt repayment obligations.  Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our short and long-term liquidity needs and achieve our intended long-term business objectives.

Financial Condition

Intangible Assets

We consider our intellectual property, including patents, patent applications, trademarks, copyrights, and trade secrets to be significant to our business.  Our intangible assets are pledged as security for our secured contingent payment obligation with Brickell.  The net book value of our intangible assets was approximately $1.4 million and $1.8 million as of December 31, 2022 and 2021, respectively.  The cost basis for our intangible assets represents capitalized legal costs and agency filing fees for securing intellectual property protection and does not include the costs expended in developing the underlying intellectual property.  The cost of our intangible assets is amortized using the straight-line method over their estimated period of benefit, generally fifteen to twenty years.  The decrease in the carrying value of our intangible assets is primarily the result of $0.3 million in patent amortization expense recognized in 2022 as our portfolio matures.  Management evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists.  As part of our ongoing patent maintenance program, we may, from time to time, abandon a particular patent if we determine fees to maintain the patent exceed its expected recoverability.  For the years ended December 31, 2022 and 2021, we incurred losses of approximately $0.1 million and $0.03 million, respectively, for the write-off of specific patent assets.  These losses are included in operating expenses in the accompanying consolidated statements of comprehensive loss included in Item 8.

Contingent Payment Obligations

We have secured and unsecured contingent payment obligations recorded at an aggregate estimated fair value of $45.8 million and $43.1 million as of December 31, 2022 and 2021, respectively.  These repayment obligations are contingent upon receipt of proceeds from patent enforcement and other patent monetization actions.  As a result, we have elected to account for these contingent payment obligations at their estimated fair values which are subject to significant estimates and assumptions as discussed in “Critical Accounting Policies” below.  Refer to Note 11 to our consolidated financial statements included in Item 8 for a discussion of the fair value measurement of our contingent payment obligations.

Our secured contingent payment obligation is payable to Brickell as a result of $18 million in borrowings under a 2016 funding agreement, as amended from time to time.  As of December 31, 2022, we have repaid Brickell an aggregate of $3.3 million to date under this agreement. The contingent payment obligation to Brickell is recorded at its estimated fair market value of $40.7 million at December 31, 2022, an increase of $3.3 million or 9% from the estimated fair market value at December 31, 2021.  Brickell is entitled to a priority, prorated payment of up to 100% of proceeds received by us from funded patent-related actions up to a specified minimum return.  Brickell’s minimum return is determined as a multiple of the outstanding funded amount that increases over time.  The estimated aggregate minimum return due to Brickell if repaid in full at December 31, 2022 is approximately $56.9 million, an increase of approximately $8.1 million, or 16.6%, from the minimum return that would have been due to Brickell as of December 31, 2021.

17

Table of Contents

In addition, in 2020 and 2021, we incurred unsecured contingent payment obligations in connection with various funding arrangements.  These contingent payment obligations are payable from our share of patent-related proceeds after satisfaction of our obligation to Brickell and payment of contingent fees to legal counsel.  These unsecured contingent payment obligations are recorded at an aggregate estimated fair value of $5.1 million at December 31, 2022, representing a decrease of $0.6 million from the estimated fair market value at December 31, 2021.  This decrease is primarily the result of the sharp increase in the risk-free interest rate used in the calculation as a result of the Federal Reserve ending bond purchases and implementing multiple rate increases during 2022.  The maximum payment obligation for our unsecured contingent payment obligations is 10.8 million at December 31, 2022.

See “Change in Fair Value of Contingent Obligations” included in “Results of Operations” below for a discussion of the changes in the estimated fair values of our secured and unsecured contingent payment obligations.

Note Payable

As of December 31, 2022, we have a $0.6 million unsecured note payable to Sterne, Kessler, Goldstein, & Fox, PLLC (“SKGF”), a related party.  We are obligated to make principal and interest payments totaling $0.16 million in 2023 under this note.  The note calls for monthly payments of $12,500 through March 2027 with a final payment of approximately $0.02 million in April 2027.  Failure to comply with the payment terms of this note constitutes an event of default which, if uncured, will result in the entire unpaid principal balance of the note and any unpaid, accrued interest to become immediately due and payable.  In addition, an event of default results in an increase in the interest rate under the notes to a default rate of 12% per annum.  Notes payable are discussed more fully in Note 8 to our consolidated financial statements included in Item 8.

Convertible Notes

As of December 31, 2022, we have $4.5 million in notes that are convertible, at the holders’ option, into shares of our common stock at fixed conversion prices ranging from $0.08 to $0.57 per share.  These notes mature at varying dates from September 2023 to August 2027.  The majority of the notes bear interest at a stated rate of 8%, payable quarterly.  We have the option, subject to certain conditions, to pay the quarterly interest in-kind with shares of our common stock based on market price at the interest payment date.  To date, all of the interest payments under these convertible notes have been paid in-kind and we anticipate that future payments of interest will also be paid in-kind. The notes provide for events of default that include failure to pay principal or interest when due, breach of any of the representations made by us, events of liquidation or bankruptcy, and a change in control.  In the event of default, the interest rate increases to 12% per annum and the outstanding principal balance of the notes plus all accrued interest due may be declared immediately payable by the holders of a majority of the then-outstanding notes.  Our convertible notes payable are more fully discussed in Note 9 to our consolidated financial statements included in Item 8.

Deferred Tax Assets and Related Valuation Allowance

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns.  Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.  Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized.  As of December 31, 2022, we had net deferred tax assets of approximately $90.5 million, primarily related to our NOL carryforwards, which were fully offset by a valuation allowance due to the uncertainty related to realization of these assets through future taxable income.  In addition, our ability to benefit from our NOL and other tax credit carryforwards could be limited under Section 382 as more fully discussed in “Risk Factors” and in Note 12 to our consolidated financial statements included in Item 8.

Results of Operations for Each of the Years Ended December 31, 2022 and 2021

Revenues and Gross Margins

Licensing revenue was $0.93 million and $0.14 for the years ended December 31, 2022 and December 31, 2021, respectively.  Our licensing revenue is from patent licensing and settlement agreements resulting from settlement of patent enforcement actions filed by us. To date, all of our license and settlement agreements have consisted of a one-time, lump sum payment with no recurring future revenue.  We recognized revenue from each contract when the parties’ performance obligations were met.  Cost of sales related to the licensing revenue consists of amortization expense related to the patents covered under the license agreements.  Our licensing revenue is expected to vary based on the market size of the licensee and the specific terms of the license and settlement agreement. 

Our licensing proceeds in both 2022 and 2021 were used fully to pay contingent out-of-pocket expenses incurred by our litigation counsel to support our patent enforcement program in the aggregate.  As a result of the recognition of these contingent expenses in accordance with our contingent fee agreements, the proceeds did not have an impact on our cash flows.  These contingent out-of-pocket expenses, which are recognized in the same period as the corresponding revenue, are included in selling, general and administrative expenses.

In March 2023, we received $25.0 million from a patent licensing and settlement agreement reached in February 2023.  We anticipate additional revenue to result from our licensing and patent enforcement actions although the amount and timing is highly unpredictable and there can be no assurance that we will achieve our anticipated results.

Selling, General, and Administrative Expenses

Selling, general and administrative expenses consist primarily of executive, director, technical support, and finance and administrative personnel costs, including share-based compensation, costs incurred for insurance, shareholder relations and outside legal and professional services, including litigation expenses, and amortization and maintenance expenses related to our patent assets.

Our selling, general and administrative expenses were approximately $7.8 million for the year ended December 31, 2022, as compared to approximately $8.1 million for the year ended December 31, 2021, representing a decrease of approximately $0.3 million or 4%.  This decrease results primarily from a decrease in share-based compensation of $0.2 million attributed to nonqualified stock options and restricted stock units becoming fully vested during the year ended December 31, 2022.  We recognized approximately $0.93 and $0.14 million in contingent litigation expenses resulting from patent license and settlement arrangements for the years ended December 31, 2022 and December 31, 2021, respectively.  The increase in contingent litigation expenses from 2021 to 2022 is a direct result of the increase in licensing revenue and was offset by a decrease in non-contingent litigation expenses from 2021 to 2022, primarily as a result of a decrease in non-contingent litigation expenses incurred in connection with the Qualcomm action that is currently on appeal.

Change in Fair Value of Contingent Payment Obligations

We have elected to measure our secured and unsecured contingent payment obligations at fair value which is based on significant unobservable inputs.  We estimated the fair value of our secured contingent payment obligations using a probability-weighted income approach based on the estimated present value of projected future cash outflows using a risk-adjusted discount rate.  Increases or decreases in the significant unobservable inputs could result in significant increases or decreases in fair value.

For the year ended December 31, 2022, we recorded an increase in the aggregate fair value of our secured and unsecured contingent payment obligations of approximately $2.7 million.  The majority of the change in fair value is attributable to the passage of time leading to increased returns due to Brickell and are partially offset by an increase in the risk-free interest rate used in the calculation as a result of the Federal Reserve ending bond purchases and implementing multiple rate increases during 2022.

Critical Accounting Policies

We believe that the following are critical accounting policies and estimates that significantly impact the preparation of our consolidated financial statements:

Contingent Payment Obligations

We have accounted for our secured and unsecured contingent payment obligations as long-term debt. Our repayment obligations are contingent upon the receipt of proceeds from patent enforcement or other patent monetization actions. We have elected to measure our contingent payment obligations at their estimated fair values based on the variable and contingent nature of the repayment provisions.  We have determined that the fair value of our secured and unsecured contingent payment obligations falls within Level 3 in the fair value hierarchy, which involves significant estimates and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows.  Actual results could differ from the estimates made.  Changes in fair value, including the component related to imputed interest, are included in the consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligations.”  Refer to Note 11 to our consolidated financial statements included in Item 8 for a discussion of the significant estimates and assumptions used in estimating the fair value of our contingent payment obligations.

Accounting for Share-Based Compensation

We calculate the fair value of share-based equity awards, including restricted stock, stock options and restricted stock units (“RSUs”), on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards.  The fair value of stock option awards is determined using the Black-Scholes option valuation model that requires the use of highly subjective assumptions and estimates including how long the holder will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award.  Changes in these subjective assumptions can materially affect the estimate of fair value of share-based compensation and consequently, the related amount recognized as expense in the consolidated statements of comprehensive loss.

New Accounting Pronouncements

We adopted Accounting Standards Update (“ASU”) 2020-06, "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" as of January 1, 2021.  ASU 2020-06 simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP.  Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features.  The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for the exception.  The ASU also simplifies the diluted earnings per share calculation in certain areas. For smaller reporting companies, the ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2020.  The ASU provides for a modified retrospective method of adoption whereby the guidance is applied to transactions outstanding at the beginning of the fiscal year of adoption with the cumulative effect of the change being recorded as an adjustment to beginning retained earnings. Adoption of ASU 2020-06 resulted in an increase to our long-term debt of approximately $0.8 million, a decrease in additional paid-in-capital of approximately $1.1 million and an adjustment to our beginning accumulated deficit of $0.3 million resulting from the elimination of the previously recognized beneficial conversion feature as a debt discount.

Off-Balance Sheet Transactions

As of December 31, 2022, we had outstanding warrants to purchase 10.3 million shares of our common stock. The estimated grant date fair value of these warrants of approximately $3.2 million is included in shareholders’ deficit in our consolidated balance sheet for the year ended December 31, 2022.  The outstanding warrants have an average exercise price of $0.75 per share and a weighted average remaining life of approximately 2.1 years.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

ParkerVision, Inc.

Jacksonville, Florida

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of ParkerVision, Inc. (the “Company”) and its subsidiary as of December 31, 2022 and 2021, and the related consolidated statements of comprehensive loss, shareholders’ deficit and cash flows for each of the years in the two-year period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company and its subsidiary as of December 31, 2022 and 2021, and the results of their operations and their cash flows for each of the years in the two-year period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt About the Entity's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations and has a net capital deficiency that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Our opinion is not modified with respect to this matter.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As a part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Estimation of Fair Value of Contingent Payment Obligations

As disclosed in Note 1 of the Company’s consolidated financial statements, the Company accounts for their secured and unsecured contingent payment obligations as long-term debt. Their payment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions. The Company has elected to measure their contingent payment obligations at their estimated fair values. The Company recorded the fair value of their contingent payment obligations at approximately $45,797,000 as of December 31, 2022.

Auditing management’s estimate of the fair value of their contingent payment obligations involved subjective evaluation and high degree of auditor judgement due to significant assumptions involved in estimating the receipt of proceeds from patent enforcement and/or patent monetization actions.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. We obtained an understanding and evaluated the design of internal controls that address the risks of material misstatement relating to recording the contingent payment obligations at fair value. We tested the accuracy and completeness of the underlying data used in calculating the fair value. We evaluated management’s ability to accurately estimate the assumptions used to develop the fair value of the contingent payment obligations. We also involved an independent legal firm to assist in evaluating the reasonableness of the assumptions of future litigation outcomes used by the Company in estimating the receipt of proceeds from patent enforcement and/or patent monetization actions.

/s/ MSL, P.A.

We have served as the Company’s auditor since 2019.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2022 AND 2021

1. SIGNIFICANT ACCOUNTING POLICIES

ParkerVision, Inc. and its wholly-owned German subsidiary, ParkerVision GmbH (collectively “ParkerVision”, “we” or the “Company”) is in the business of innovating fundamental wireless hardware technologies and products. We have determined that our business currently operates under a single operating and reportable segment.

We have designed and developed proprietary radio frequency (“RF”) technologies and integrated circuits based on those technologies, and we license our technologies to others for use in wireless communication products.  We have expended significant financial and other resources to research and develop our RF technologies and to obtain patent protection for those technologies in the United States of America (“U.S.”) and certain foreign jurisdictions.  We believe certain patents protecting our proprietary technologies have been broadly infringed by others, and therefore the primary focus of our business plan is the enforcement of our intellectual property rights through patent licensing and infringement litigation efforts.  We currently have patent enforcement actions ongoing in various U.S. district courts against mobile handset, smart television and other WiFi product providers, as well as semiconductor suppliers for the infringement of a number of our RF patents.  We have made significant investments in developing and protecting our technologies, the returns on which are dependent upon the generation of future revenues for realization.

Basis of Presentation

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”).  Certain reclassifications have been made to prior period amounts to conform to the current period presentation.  The consolidated financial statements include the accounts of ParkerVision, Inc. and our wholly-owned German subsidiary, ParkerVision GmbH, after elimination of all intercompany transactions and accounts.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods.  The more significant estimates made by us include projected future cash flows and risk-adjusted discount rates for estimating the fair value of our contingent payment obligations, the volatility and estimated lives of share-based awards used in the estimate of the fair market value of share-based compensation, the assessment of recoverability of long-lived assets, the amortization periods for intangible and long-lived assets, and the valuation allowance for deferred taxes.  Actual results could differ from the estimates made.  We periodically evaluate estimates used in the preparation of the financial statements for continued reasonableness.  Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation.

Cash and Cash Equivalents

We consider cash and cash equivalents to include cash on hand, interest-bearing deposits, overnight repurchase agreements and investments with original maturities of three months or less when purchased.

Intangible Assets

We capitalize outside legal costs and agency filing fees incurred in connection with securing the rights to our intellectual property.  Patents, copyrights, and other intangible assets are amortized using the straight-line method over their estimated period of benefit.  We estimate the economic lives of our patents and copyrights to be fifteen to twenty years.  Management evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate impairment exists.  As part of our ongoing patent maintenance program, we will, from time to time, abandon a particular patent if we determine fees to maintain the patent exceed its expected recoverability.  The cost and accumulated amortization of abandoned intangible assets are removed from their respective accounts, and any resulting net loss is recognized in selling, general and administrative expenses in the accompanying consolidated statements of comprehensive loss.

29

Table of Contents

Contingent Payment Obligations

We have accounted for our secured and unsecured contingent payment obligations as long-term debt in accordance with Accounting Standards Codification (“ASC”) 470-10-25, “Sales of Future Revenues or Various other Measures of Income.”  Our payment obligations are contingent upon the receipt of proceeds from patent enforcement and/or patent monetization actions.  We have elected to measure our contingent payment obligations at their estimated fair values in accordance with ASC 825, “Financial Instruments” based on the variable and contingent nature of the repayment provisions.  We have determined that the fair value of our secured and unsecured contingent payment obligations falls within Level 3 in the fair value hierarchy, which involves significant estimates, and assumptions including projected future patent-related proceeds and the risk-adjusted rate for discounting future cash flows (see Note 11).  Actual results could differ from the estimates made.  Changes in fair value, including the component related to imputed interest, are included in the accompanying consolidated statements of comprehensive loss under the heading “Change in fair value of contingent payment obligations.”

Leases

We have accounted for our finance and operating leases in accordance with ASC 842, “Leases” which requires the recognition of lease right-of-use (“ROU”) assets and lease liabilities on our consolidated balance sheets for finance and operating leases with initial lease terms of more than 12 months. At inception of a lease, we determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease.  Some of our lease arrangements contain lease components (e.g., minimum rent payments) and non-lease components (e.g., services).  For certain equipment leases, we account for lease and non-lease components separately based on a relative fair market value basis.  For all other leases, we account for the lease and non-lease components (e.g., common area maintenance) on a combined basis.

For operating leases with terms greater than 12 months, we record the ROU asset and lease obligation at the present value of lease payments over the term using the implicit interest rate, when readily available, or our incremental borrowing rate for collateralized debt based on information available at the lease commencement date.  Certain of our leases include rental escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments when it is reasonably certain that the option will be exercised.  We do not recognize ROU assets and lease liabilities for leases with terms at inception of twelve months or less.

Finance leases are included in property and equipment and other accrued expenses on the consolidated balance sheets.  Finance leases are recorded as an asset and an obligation at an amount equal to the present value of the minimum lease payments during the lease term.  Amortization expense and interest expense associated with finance leases are included in selling, general, and administrative expense and interest expense, respectively, on the consolidated statements of comprehensive loss.

Refer to Note 7 for additional disclosures related to our leases.

Convertible Debt

We have issued debt that is convertible, at the holder’s option, into shares of our common stock at fixed conversion prices.  Certain of the convertible notes were issued with conversion prices that were below market value of our common stock on the closing date resulting in a beneficial conversion feature which we recorded to equity with a corresponding discount to the debt that was amortized over the life of the notes as interest expense.

30

Table of Contents

Effective January 1, 2021, we adopted Accounting Standards Update (“ASU”) 2020-06 "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity."  This ASU simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP.  Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features.  The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for the exception.  The ASU also simplifies the diluted earnings per share calculation in certain areas.  For smaller reporting companies, the ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2020.  The ASU provides for a modified retrospective method of adoption whereby the guidance is applied to transactions outstanding at the beginning of the fiscal year of adoption with the cumulative effect of the change being recorded as an adjustment to beginning retained earnings.

Adoption of ASU 2020-06 resulted in an increase to our long-term debt of approximately $0.8 million, a decrease in additional paid-in-capital of approximately $1.1 million, and an adjustment to our beginning accumulated deficit of $0.3 million resulting from the elimination of the previously recognized beneficial conversion feature as a debt discount.

Revenue Recognition

We account for revenue under ASC 606, “Revenue from Contracts with Customers” which implements a common revenue standard that clarifies the principles for recognizing revenue.  This revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. These steps include (1) identifying the contract with the customer, (2) identifying the performance obligations, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations, and (5) recognizing revenue as the entity satisfies the performance obligation(s).

Our revenue is derived from patent licensing and settlement agreements.  We have an active monitoring and enforcement program with respect to our intellectual property rights that includes seeking appropriate compensation from third parties that utilize or have utilized our intellectual property without a license. As a result, we may receive payments as part of a settlement or in the form of court-awarded damages for a patent infringement dispute.  The timing and amount of revenue recognized from each licensee depend upon a variety of factors, including the specific terms of each agreement and the nature of the deliverables and obligations. Such agreements are often complex and may include multiple performance obligations.  These agreements can include performance obligations related to the settlement of past patent infringement liabilities, royalties on future covered products sold by licensees, access to a portfolio of technology as it exists at a point in time, and/or promises to provide technology updates to the portfolio during the term of the license.

Refer to Note 3 for additional disclosures related to our revenue.

Cost of Sales

Cost of sales includes amortization of intangible assets directly linked with revenue generating licensing activities.  Amortization expense for intangible assets that are not directly related to revenue generating licensing activities are included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss.

Accounting for Share-Based Compensation

We have various share-based compensation programs which provide for equity awards including stock options, restricted stock units (“RSUs”) and restricted stock awards (“RSAs”).  We calculate the fair value of share-based equity awards on the date of grant and recognize the calculated fair value as compensation expense over the requisite service periods of the related awards.  We estimate the fair value of stock option awards using the Black-Scholes option valuation model.  This valuation model requires the use of highly subjective assumptions and estimates including how long employees will retain their stock options before exercising them and the volatility of our common stock price over the expected life of the equity award. Such estimates, and the basis for our conclusions regarding such estimates, are outlined in detail in Note 15.  Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards. We account for forfeitures of share-based awards as they occur.

31

Table of Contents

Income Taxes

The provision for income taxes is based on loss before taxes as reported in the accompanying consolidated statements of comprehensive loss.  Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns.  Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse.  Valuation allowances are established to reduce deferred tax assets when, based on available objective evidence, it is more likely than not that the benefit of such assets will not be realized.  Our deferred tax assets exclude unrecognized tax benefits which do not meet a more-likely-than-not threshold for financial statement recognition for tax positions taken or expected to be taken in a tax return.

Loss per Common Share

Basic loss per common share is determined based on the weighted-average number of common shares outstanding during each year.  Diluted loss per common share is the same as basic loss per common share as all potential common shares are excluded from the calculation, as their effect is anti-dilutive.

The number of shares underlying outstanding options, warrants, and convertible notes at December 31, 2022 and 2021 were as follows (in thousands):

	2022		2021
Options outstanding		24,380		23,215
Warrants outstanding		10,346		10,346
Shares underlying convertible notes		32,734		20,157
		67,460		53,718

These potential shares were excluded from the computation of diluted loss per share as their effect would have been anti-dilutive.

2. LIQUIDITY AND GOING CONCERN

The accompanying consolidated financial statements as of and for the year ended December 31, 2022 were prepared assuming we will continue as a going concern, which contemplates that we will continue in operation and will be able to realize our assets and settle our liabilities and commitments in the normal course of business for a period of at least one year from the issuance date of these consolidated financial statements.  These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that could result should we be unable to continue as a going concern.

We have incurred significant losses from operations and negative cash flows in every year since inception and have utilized the proceeds from the sales of our equity and equity-linked securities and our contingent funding arrangements with third parties to fund our operations, including our litigation costs.  For the year ended December 31, 2022, we incurred a net loss of approximately $9.8 million and negative cash flows from operations of approximately $3.0 million.  At December 31, 2022, we had an accumulated deficit of approximately $443.2 million. These circumstances raise substantial doubt about our ability to continue to operate as a going concern for a period of one year after the issuance date of these consolidated financial statements.

We had cash and cash equivalents of approximately $0.1 million at December 31, 2022.  We received an additional $0.8 million in proceeds from debt and equity financings in January 2023 (see Note 18).  Our remaining capital resources will be used to fund our current obligations and ongoing operating costs; however, these resources will not be sufficient to meet our liquidity needs for the next twelve months and we will be required to seek additional capital.

32

Table of Contents

Our business plan is currently focused solely on our patent enforcement and technology licensing objectives.  The timing and amount of proceeds from our patent enforcement actions are difficult to predict and there can be no assurance we will receive any proceeds from these enforcement actions. Refer to Note 13 for a complete discussion of our patent enforcement proceedings.

Significant portions of our litigation costs to date have been funded by contingent payment arrangements with legal counsel.  Fee discounts offered by legal counsel in exchange for contingent payments upon successful outcome in our litigation are not recognized in expense until such time that the related proceeds on which the contingent fees are payable are considered probable.  Contingent fees vary based on each firm’s specific fee agreement.  We currently have contingent fee arrangements in place for all of our active cases. In addition to our contingent fee agreements with legal counsel, we have secured and unsecured contingent payment obligations to litigation funders that have priority payments due from patent-related proceeds.

In March 2023, we received $25.0 million in proceeds from a patent license and settlement agreement (see Note 18).  These proceeds are expected to be used entirely for the payment of contingent legal fees and expenses and the repayment of principal on our secured contingent payment obligation and therefore our ability to meet our liquidity needs for the twelve months after the issuance date  of these financial statements is dependent upon one or more of (i) our ability to successfully negotiate future licensing agreements and/or settlements relating to the use of our technologies by others in excess of our contingent payment obligations; and/or (ii) our ability to raise additional capital from the sale of debt or equity securities or other financing arrangements.  We are currently in discussions with Brickell regarding restructuring of our contingent payment obligation, including additional new capital.  There can be no assurance that a favorable restructuring of our Brickell obligation will be achieved at all, or in a manner that provides significant future benefit to us.  

The long-term continuation of our business plan is dependent upon our ability to secure sufficient financing to support our business, and our ability to generate revenues and/or patent-related proceeds sufficient to offset expenses and meet our contingent payment obligation and other long-term debt repayment obligations.  Failure to generate sufficient revenues, raise additional capital through debt or equity financings, and/or reduce operating costs could have a material adverse effect on our ability to meet our short and long-term liquidity needs and achieve our intended long-term business objectives.

3. REVENUE

During the years ended December 31, 2022 and 2021, we recognized $0.93 million and $0.14 million of revenue, respectively, derived from contracts with licensees.  The contracts provide access to specified patented technologies as they exist at a point in time, and we have no obligation to provide any future updates.  The consideration received by us was negotiated as part of a settlement of patent litigation where no prior license agreement existed.  The performance obligations were satisfied upon our dismissal of patent enforcement actions with each licensee which was contingent upon our receipt of the negotiated and agreed-upon lump-sum payments from the licensees.  The contracts included no variable consideration.  All consideration received was recorded to licensing revenue as there were no other material components of the contracts.  No contract assets or liabilities exist as of December 31, 2022.

4. PREPAID EXPENSES

Prepaid expenses consisted of the following at December 31, 2022 and 2021 (in thousands):

	2022		2021
Prepaid services	$	202	$	523
Prepaid insurance		25		23
Prepaid licenses, software tools and support		15		16
Other prepaid expenses		2		12
	$	244	$	574

Prepaid services at December 31, 2022 and 2021 include approximately $0.2 million and $0.5 million, respectively, of consulting services paid in shares of stock or warrants to purchase shares of stock in the future.

7. LEASES

We lease our office and other facilities and certain office equipment under long-term, non-cancelable operating leases.  No new finance or operating leases commenced during the years ended December 31, 2022 or 2021 except with respect to a sublease agreement for our Lake Mary facility in 2021.  The sublease was accounted for as an operating lease and expired in November 2022 in connection with the expiration of our corresponding Lake Mary facility lease.

Lease expense for operating leases is generally recognized on a straight-line basis over the lease term and is included in operating expenses on the consolidated statement of comprehensive loss.  We recognized operating lease costs of $0.04 million for each of the years ended December 31, 2022 and 2021.  Rental income recognized of $0.11 million and $0.05 million for the years ended December 31, 2022 and 2021, respectively, is included in “Interest and other income” in the accompanying consolidated statements of comprehensive loss.

9. Convertible Notes

Our convertible notes represent five-year promissory notes that are convertible, at the holders’ option, into shares of our common stock at fixed conversion prices.  Interest payments are made on a quarterly basis and are payable, at our option and subject to certain equity conditions, in either cash, shares of our common stock, or a combination thereof.  The number of shares issued for interest is determined by dividing the interest payment amount by the closing price of our common stock on the trading day immediately prior to the scheduled interest payment date.  To date, all interest payments on the convertible notes have been made in shares of our common stock.  We have recognized the convertible notes as debt in our consolidated financial statements.  The fixed conversion prices of certain of the notes were below the market value of our common stock on the closing date resulting in the recognition of a beneficial conversion feature that was recorded as a discount on the convertible notes with a corresponding increase to additional paid in capital.  Upon our adoption of ASU 2020-06 on January 1, 2021, the previously recognized beneficial conversion feature was eliminated resulting in an increase in convertible notes of $0.8 million (see Note 1).

We have the option to prepay the majority of the notes any time following the one-year anniversary of the issuance of the notes, subject to a premium on the outstanding principal prepayment amount of 25% prior to the two-year anniversary of the note issuance date, 20% prior to the three-year anniversary of the note issuance date, 15% prior to the four-year anniversary of the note issuance date, or 10% thereafter.  The notes provide for events of default that include failure to pay principal or interest when due, breach of any of the representations, warranties, covenants, or agreements made by us, events of liquidation or bankruptcy, and a change in control.  In the event of default, the interest rate increases to 12% per annum and the outstanding principal balance of the notes plus all accrued interest due may be declared immediately payable by the holders of a majority of the then outstanding principal balance of the notes.

For the year ended December 31, 2022, a convertible note with a face value of $0.03 million was converted by the holder into 0.3 million shares of our common stock at a conversion price of $0.10. For the year ended December 31, 2021, convertible notes with a face value of $0.97 million were converted by the holders into 3.4 million shares of our common stock at an average conversion price of $0.29. At the holders’ option, subject to ownership limitations, the convertible notes outstanding at December 31, 2022 could be converted into an aggregate of approximately 32.7 million shares of our common stock based on the fixed conversion prices.

For the years ended December 31, 2022 and 2021, we recognized interest expense of approximately $0.30 million and $0.26 million, respectively. We have elected to pay contractual interest in shares of our common stock. For the years ended December 31, 2022 and 2021, we issued approximately 1,203,000 and 272,000 shares of our common stock, respectively, as interest-in-kind payments on our convertible notes.

In 2022 we sold five-year convertible promissory notes for aggregate proceeds of $1.7 million.  The notes have a conversion price of $0.13 per share.  The shares underlying the notes, as well as shares reserved for future in-kind interest payments on the notes, were registered on a registration statement that was declared effective on August 22, 2022 (File No. 333-266777).  In January 2023, we sold additional five-year convertible promissory notes for aggregate proceeds of $0.7 million (see Note 18).

All of the shares underlying our convertible notes, including shares reserved for future in-kind interest payments on the notes, have been or will be registered for resale.

Table of Contents

Our secured contingent payment obligation represents the estimated fair value of our repayment obligation to Brickell Key Investments, LP (“Brickell”) under a February 2016 funding agreement, as amended from time to time (the “CPIA”).  To date, we have received aggregate proceeds of $18 million in exchange for Brickell’s right to reimbursement and compensation from gross proceeds resulting from patent enforcement and other patent monetization actions.  No proceeds were received from Brickell in 2022 or 2021.  To date, we have repaid an aggregate of $3.3 million under the CPIA from patent license and settlement proceeds.

Brickell is entitled to priority payment of 100% of proceeds received by us, after reimbursement of out-of-pocket expenses and legal contingent fees, from all patent-related actions until such time that Brickell has been paid its remaining principal of approximately $14.7 million.  Thereafter, Brickell is entitled to a significant portion of remaining proceeds from all patent-related actions until such time that Brickell has been repaid its minimum return.  The minimum return is determined as a multiple of the funded amount that increases over time.  The estimated minimum return due to Brickell was approximately $56.9 million and $48.8 million as of December 31, 2022 and 2021, respectively.  In addition, Brickell is entitled to a pro rata portion of proceeds from specified legal actions to the extent aggregate proceeds from those actions exceed the minimum return.

Brickell holds a senior security interest in the majority of our assets until such time as the specified minimum return is paid, in which case, the security interest will be released except with respect to the patents and proceeds related to specific legal actions.  The security interest is enforceable by Brickell in the event that we are in default under the agreement which would occur if (i) we fail, after notice, to pay proceeds to Brickell, (ii) we become insolvent or insolvency proceedings are commenced (and not subsequently discharged) with respect to us, (iii) our creditors commence actions against us (which are not subsequently discharged) that affect our material assets, (iv) we, without Brickell’s consent, incur indebtedness other than immaterial ordinary course indebtedness, or (v) there is an uncured non-compliance of our obligations or misrepresentations under the agreement.  As of December 31, 2022, we are in compliance with our obligations under this agreement.

In addition, in the event of a change in control of the Company, Brickell has the right to be paid its return as defined under the CPIA based on the transaction price for the change in control event.

We have elected to measure our secured contingent payment obligation at its estimated fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods (see Note 11). The secured contingent payment obligation is remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved.

Unsecured Contingent Payment Obligations

The following table provides a reconciliation of our unsecured contingent payment obligations, measured at estimated fair market value, for the years ended December 31, 2022 and 2021, respectively (in thousands):

Change in fair value		(602	)		57
Unsecured contingent payment obligations, end of period	$	5,089		$	5,691

Table of Contents

Our unsecured contingent payment obligations represent amounts payable to others from future patent-related proceeds including (i) a termination fee due to a litigation funder (“Termination Fee”) and (ii) contingent payment rights (“CPRs”) issued to accredited investors primarily in connection with equity financings.  We have elected to measure these unsecured contingent payment obligations at their estimated fair value based on probability-weighted estimated cash outflows, discounted back to present value using a discount rate determined in accordance with accepted valuation methods.  The unsecured contingent payment obligations will be remeasured to fair value at each reporting period with changes recorded in the consolidated statements of comprehensive loss until the contingency is resolved (see Note 11).

The Termination Fee is a result of $1.0 million in advances received under a letter agreement with a third-party funder.  Based on the terms of the letter agreement, if a final funding arrangement was not executed by March 31, 2020, we would be obligated to pay, from future patent-related proceeds, an aggregate termination payment equal to five times the advances received, or approximately $5.0 million.  We did not consummate a funding agreement and accordingly the advances were recorded as an unsecured contingent payment obligation at March 31, 2020, when the Termination Fee obligation was incurred.  As of December 31, 2022, the estimated fair value of unsecured contingent payment obligations related to the Termination Fee is $2.4 million.

The CPRs represent the estimated fair value of rights provided to accredited investors who purchased shares of our common stock in 2020 and 2021 and the fair value of a right issued to a third-party in connection with a service agreement during the year ended December 31, 2020.  During the year ended December 31, 2021, we received aggregate proceeds of $1.1 million from the sale of common stock with contingent payment rights, of which approximately $0.4 million was allocated to the CPRs.  No sales of common stock with contingent payment rights were completed during the year ended December 31, 2022.  The terms of the CPRs provide that we will pay each investor an allocated portion of our net proceeds from patent-related actions, after taking into account fees and expenses payable to law firms representing us and amounts payable to Brickell.  The investors’ allocated portion of net proceeds will be determined by multiplying the net proceeds recovered by us (up to $10 million) by the quotient of such investors’ subscription amount divided by $10 million, up to an amount equal to each investor’s subscription amount, or an aggregate of $5.8 million.  As of December 31, 2022, the estimated fair value of our unsecured contingent payment obligations related to the CPRs is $2.7 million.

11. FAIR VALUE MEASUREMENTS

ASC 820, “Fair Value Measurements” establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value.  The three levels of the fair value hierarchy are as follows:

● Level 1: Quoted prices for identical assets or liabilities in active markets which we can access

● Level 2: Observable inputs other than those described in Level 1

● Level 3: Unobservable inputs

40

Table of Contents

The following table summarizes financial assets and financial liabilities carried at fair value and measured on a recurring basis as of December 31, 2022 and 2021, segregated by classification within the fair value hierarchy (in thousands):

			Fair Value Measurements
	Total		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
December 31, 2022:
Liabilities:
Secured contingent payment obligation	$	40,708	$	-	$	-	$	40,708
Unsecured contingent payment obligations		5,089		-		-		5,089

Liabilities:
Secured contingent payment obligation		37,372		-		-		37,372
Unsecured contingent payment obligations		5,691		-		-		5,691

For the years ended December 31, 2022 and 2021, respectively, we had no transfers of assets or liabilities between the levels of the hierarchy.

The fair values of our secured and unsecured contingent payment obligations were estimated using a probability-weighted income approach based on various cash flow scenarios as to the outcome of patent-related actions both in terms of timing and amount, discounted to present value using a risk-adjusted rate.  We used a risk-adjusted discount rate of 18.41% at December 31, 2022, based on a risk-free rate of 4.41% as adjusted by 8% for credit risk and 6% for litigation inherent risk.

The following table provides quantitative information about the significant unobservable inputs used in the measurement of fair value for both the secured and unsecured contingent payment obligations at December 31, 2022, including the lowest and highest undiscounted payout scenarios as well as a weighted average payout scenario based on relative undiscounted fair value of each cash flow scenario.

	Secured Contingent Payment Obligation									Unsecured Contingent Payment Obligations
Unobservable Inputs	Low			Weighted Average			High			Low			Weighted Average			High
Estimated undiscounted cash outflows (in millions)	$	0.0		$	59.6		$	88.4		$	0.0		$	7.5		$	10.8
Duration (in years)		1.0			2.2			2.5			1.5			2.3			2.5
Estimated probabilities		5	%		17	%		35	%		5	%		18	%		35	%

We evaluate the estimates and assumptions used in determining the fair value of our contingent payment obligations each reporting period and make any adjustments prospectively based on those evaluations.  Changes in any of these Level 3 inputs could result in a significantly higher or lower fair value measurement.

12. INCOME TAXES AND TAX STATUS

Our net losses before income taxes for the years ended December 31, 2022 and 2021 are from domestic operations as well as losses from our wholly-owned German subsidiary.  We elected to treat our German subsidiary as a disregarded entity for purposes of income taxes and accordingly, the losses from our German subsidiary have been included in our operating results.

No current or deferred tax provision or benefit was recorded in 2022 or 2021 as a result of current losses and fully deferred tax valuation allowances for all periods.  We have recorded a valuation allowance to state our deferred tax assets at their estimated net realizable value due to the uncertainty related to realization of these assets through future taxable income.

A reconciliation between the provision for income taxes and the expected tax benefit using the federal statutory rate of 21% for each of the years ended December 31, 2022 and 2021, respectively are as follows (in thousands):

Upon adoption of ASU 2020-06 on January 1, 2021 (see Note 9), the difference between the financial accounting and tax bases, net of tax effect, of unrecognized tax benefit related to the beneficial conversion feature of convertible debt was eliminated.

At December 31, 2022, we had cumulative net operating loss (“NOL”) carry-forwards for income tax purposes of $300.8 million, of which $260.1 million is subject to expiration in varying amounts from 2023 to 2037. At December 31, 2022, we also had research and development tax credit carryforwards of $5.4 million, which expire in varying amounts from 2023 through 2038.

Our ability to benefit from the tax credit carry-forwards could be limited under certain provisions of the Internal Revenue Code if there are ownership changes of more than 50%, as defined by Section 382 of the Internal Revenue Code of 1986 (“Section 382”).  Under Section 382, an ownership change may limit the amount of NOL, capital loss and R&D credit carry-forwards that can be used annually to offset future taxable income and tax, respectively.  In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period.  We conduct a study annually of our ownership changes.  Based on the results of our studies, we have determined that we do not have any ownership changes on or prior to December 31, 2022 which would result in limitations of our NOL, capital loss or R&D credit carry-forwards under Section 382.

Uncertain Tax Positions

We file income tax returns in the U.S. federal jurisdiction, various state jurisdictions, and Germany.  We have identified our Federal and Florida tax returns as our only major jurisdictions, as defined.  The periods subject to examination for those returns are the 2003 through 2022 tax years.  The following table provides a reconciliation of our unrecognized tax benefits due to uncertain tax positions for the years ended December 31, 2022 and 2021, respectively (in thousands):

	2022			2021
Unrecognized tax benefits – beginning of year	$	653		$	927
Reduction as a result of lapse of statute of limitations		(15	)		(274	)
Unrecognized tax benefits – end of year	$	638		$	653

Future changes in the unrecognized tax benefit will have no impact on the effective tax rate so long as we maintain a full valuation allowance.

Our policy is that we recognize interest and penalties accrued on any unrecognized tax benefits as a component of our income tax expense.  We do not have any accrued interest or penalties associated with any unrecognized tax benefits.  For the years ended December 31, 2022 and 2021, we did not incur any income tax-related interest income, expense or penalties. 

13. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

From time to time, we are subject to legal proceedings and claims which arise in the ordinary course of our business.  These proceedings include patent enforcement actions initiated by us against others for the infringement of our technologies, as well as proceedings brought by others against us at the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office (“PTAB”) in an attempt to invalidate certain of our patent claims.

43

Table of Contents

The majority of our litigation, including our PTAB proceedings, is being paid for through contingency fee arrangements with our litigation counsel as well as third-party litigation financing.  In general, litigation counsel is entitled to recoup on a priority basis, from litigation proceeds, any out-of-pocket expenses incurred. Following reimbursement of out-of-pocket expenses, litigation counsel is generally entitled to a percentage of remaining proceeds based on the terms of the specific arrangement between us, counsel and our third-party litigation funder.

ParkerVision v. Qualcomm (Middle District of Florida-Orlando Division) - Appealed to U.S. Court of Appeals for the Federal Circuit

We have appealed certain March 2022 rulings by the Middle District of Florida in our patent infringement complaint against Qualcomm Incorporated and Qualcomm Atheros, Inc. (collectively “Qualcomm”).  Appellate court briefs have been filed by both parties and we are awaiting a hearing date in this matter.  

The patent infringement case was filed in the Middle District of Florida in May 2014. The case was stayed in February 2016 pending decisions in other cases, including the appeal of a PTAB proceeding with regard to U.S. patent 6,091,940 (“the ‘940 Patent”) asserted in this case.  In March 2017, the PTAB ruled in our favor on three of the six petitions (the method claims), ruled in Qualcomm’s favor on two of the six petitions (the apparatus claims) and issued a split decision on the claims covered in the sixth petition.  In September 2018, the Federal Circuit upheld the PTAB’s decision with regard to the ‘940 Patent and, in January 2019, the court lifted the stay in this case.  In July 2019, the court issued an order that granted our proposed selection of patent claims from four asserted patents, including the ‘940 Patent, and denied Qualcomm’s request to limit the claims and patents.  The court also agreed that we may elect to pursue accused products that were at issue at the time the case was stayed, as well as new products that were released by Qualcomm during the pendency of the stay.  In September 2019, Qualcomm filed a motion for partial summary judgment in an attempt to exclude certain patents from the case, including the ‘940 Patent.  The court denied this motion in January 2020.  

In April 2020, the court issued its claim construction order in which the court adopted our proposed construction for seven of the ten disputed terms and adopted slightly modified versions of our proposed construction for the remaining terms.  Due to the impact of COVID-19, a number of the scheduled deadlines in this case were moved including the trial commencement date which was rescheduled from December 2020 to May 2021.  In October 2020, our damages expert submitted a report supporting our damages ask of $1.3 billion for Qualcomm’s unauthorized use of our technology.  Such amount excludes additional amounts requested by us for interest and enhanced damages for willful infringement.  Ultimately, the amount of damages, if any, will be determined by the court.  Discovery was expected to close in December 2020; however, the court allowed us to designate a substitute expert due to medical issues with one of our experts in the case.  Accordingly, the close of discovery was delayed until January 2021.  As a result of these delays, the court rescheduled the trial commencement date from May 3, 2021 to July 6, 2021.

In March 2021, the court further delayed the trial date citing backlog due to the pandemic, among other factors.  A new trial date was not set and the court indicated the case was unlikely to be tried before November or December 2021.  Fact and expert discovery was completed, expert reports were submitted, and summary judgment and Daubert briefings were submitted by the parties.  Joint pre-trial statements were submitted in May 2021.  In March 2021, the court granted Qualcomm’s motion to strike certain of our 2020 infringement contentions.  As a result of this ruling, in July 2021, we filed a joint motion for entry of a judgment of non-infringement of our Patent No. 7,865,177 (“the ‘177 Patent”), subject to appeal.

44

Table of Contents

In January 2022, the court held a hearing to allow the parties to present their respective positions on three outstanding motions.  The court indicated that upon its ruling on these motions, a pre-trial conference would be scheduled and a trial date set.  On March 9, 2022, the court ruled with respect to one of these motions granting Qualcomm’s motion to strike and exclude opinions regarding the alleged infringement and validity issues.  This court order precluded the presentation of infringement and validity opinions by both of our experts at trial.  On March 22, 2022, the court issued an order granting Qualcomm’s motion for summary judgment ruling that Qualcomm does not infringe the remaining three patents in this case.  On April 20, 2022, we filed a notice of appeal to the United States Court of Appeals for the Federal Circuit.  As a result of the court’s summary judgment motion in favor of Qualcomm, Qualcomm has the right to petition the court for its fees and costs.  The court has granted a Qualcomm motion to delay such a petition until 30 days following the appellate court’s decision.  We are represented in this case on a full contingency fee basis.

ParkerVision v. Apple and Qualcomm (Middle District of Florida-Jacksonville Division)

In December 2015, we filed a patent infringement complaint in the Middle District of Florida against Apple Inc. (“Apple”), LG Electronics, Inc., LG Electronics U.S.A., Inc., and LG Electronics MobileComm U.S.A., Inc. (collectively “LG”), Samsung Electronics Co. Ltd., Samsung Electronics America, Inc., Samsung Telecommunications America LLC, and Samsung Semiconductor, Inc. (collectively “Samsung”), and Qualcomm alleging infringement of four of our patents.  In February 2016, the district court proceedings were stayed pending resolution of a corresponding case filed at the International Trade Commission (“ITC”).  In July 2016, we entered into a patent license and settlement agreement with Samsung and, as a result, Samsung was dismissed from the district court action.  In March 2017, we filed a motion to terminate the ITC proceedings and a corresponding motion to lift the stay in the district court case.  This motion was granted in May 2017.  In July 2017, we filed a motion to dismiss LG from the district court case and re-filed our claims against LG in the District of New Jersey (see ParkerVision v. LG below).  Also in July 2017, Qualcomm filed a motion to change venue to the Southern District of California, and Apple filed a motion to dismiss for improper venue. In March 2018, the district court ruled against the Qualcomm and Apple motions.  The parties also filed a joint motion in March 2018 to eliminate three of the four patents in the case in order to expedite proceedings leaving our U.S. patent 9,118,528 as the only remaining patent in this case.  A claim construction hearing was held on August 31, 2018. In July 2019, the court issued its claim construction order in which the court adopted our proposed claim construction for two of the six terms and the “plain and ordinary meaning” on the remaining terms.  In addition, the court denied a motion filed by Apple for summary judgment.  Fact discovery has closed in this case and a jury trial was scheduled to begin in August 2020.  In March 2020, as a result of the impact of COVID-19, the parties filed a motion requesting an extension of certain deadlines in the case.  In April 2020, the court stayed this proceeding pending the outcome of the infringement case against Qualcomm in the Orlando Division of the Middle District of Florida, which is currently pending an appeal.  

ParkerVision v. LG (District of New Jersey)

In July 2017, we filed a patent infringement complaint in the District of New Jersey against LG for the alleged infringement of four patents previously asserted against LG in the Middle District of Florida (see ParkerVision v. Apple and Qualcomm above).  We elected to dismiss the case in the Middle District of Florida and re-file in New Jersey as a result of a Supreme Court ruling regarding proper venue.  In March 2018, the court stayed this case pending a final decision in ParkerVision v. Apple and Qualcomm in the Middle District of Florida.  As part of this stay, LG has agreed to be bound by the final claim construction decision in that case.

ParkerVision v. Intel (Western District of Texas)

In February 2020, we filed a patent infringement complaint in the Western District of Texas against Intel Corporation (“Intel”) alleging infringement of eight of our patents.  The complaint was amended in May 2020 to add two additional patents. In June 2020, we requested that one of the patents be dropped from this case and filed a second case in the Western District of Texas that included this dismissed patent (see ParkerVision v. Intel II below).  Intel’s response to our complaint was filed in June 2020 denying infringement and claiming invalidity of the patents. Intel also filed a motion to transfer venue which the court denied.  In July 2020 and September 2020, Intel filed petitions for Inter Partes Review ("IPR") against two of the patents in this case and in January 2021, the PTAB instituted proceedings with regard to these two petitions (see Intel v. ParkerVision (PTAB) below).

Table of Contents

The court issued its claim construction ruling in January 2021 in which the majority of the disputed claim terms were decided in our favor.  The case was scheduled for trial beginning February 7, 2022.  In April 2021, we filed an amended complaint to include additional Intel semiconductors and products, including WiFi devices, to the complaint.  The court suggested that, given the number of patents at issue, the case would be separated into two trials and, as a result of the added products, the first trial date was moved to June 2022.

In January 2022, the PTAB issued its ruling on the IPRs (see Intel v. ParkerVision (PTAB) below).  In February 2022, the parties filed a joint motion with respect to both Intel cases whereby the first case would be narrowed to six total patents asserted against Intel cellular products.  These same six patents would be also asserted in the second Intel case, along with one additional patent from the second case, against Intel WiFi and Bluetooth products.  As a result of the restructuring of the two cases, the trial date was moved to October 2022.  In March 2022, due to discovery delays, the court agreed to move the trial commencement date to December 5, 2022.  In March 2022, Intel filed a motion requesting further claim construction which we opposed, and the court denied.  In May 2022, we filed a motion to amend our complaint to add willful infringement based on information obtained during discovery.  The court granted this motion in June 2022 and we filed an amended complaint.  As a result of additional discovery allowed by the court, the trial date was rescheduled from December 5, 2022 to February 6, 2023.  

Beginning in November 2022, the parties filed a number of pre-trial motions.  The court held hearings on these pre-trial motions in January 2023.  The court issued its written orders with regard to these motions immediately prior to the February 6, 2023 trial start date.  As a result of the court's pre-trial rulings, the potential damages in the case decreased significantly.  On February 7, 2023, the parties resolved their outstanding dispute and we have dismissed all pending actions against Intel (see Note 18).

ParkerVision v. Intel II (Western District of Texas)

In June 2020, to reduce the number of claims in ParkerVision v. Intel, we filed a second patent infringement complaint in the Western District of Texas against Intel that included a single patent that we voluntarily dismissed from the original case.  In July 2020, we amended our complaint adding two more patents to the case.  Intel responded to the complaint denying infringement and claiming invalidity of the patents.  In January 2021, Intel filed a petition for IPR against one of the patents in this case and in July 2021, the PTAB instituted proceedings with regard to this petition (see Intel v. ParkerVision (PTAB) below).  We filed an amended complaint in 2021 adding Intel WiFi and Bluetooth products to the case.  Two claim construction hearings were held in June 2021 and July 2021 and the court’s claim construction ruling was largely decided in our favor.  The case was scheduled for trial in October 2022.  In February 2022, the parties filed a joint motion which provided that the Intel II case would assert the same six patents from the first Intel case, provided none of the patents were invalidated in the first case, as well as one additional patent, depending on the outcome of the pending IPR proceeding.  On February 7, 2023, the parties resolved their outstanding dispute and we have dismissed all pending actions against Intel (see Note 18).

Intel v. ParkerVision (PTAB)

Intel filed IPR petitions against U.S. patent 7,539,474 (“the ‘474 Patent”) and U.S. patent 7,110,444 ("the ‘444 Patent") which were both asserted in ParkerVision v. Intel.  Intel also filed a petition for IPR against U.S. patent 8,190,108 (“the ‘108 patent”) which is asserted in ParkerVision v. Intel II.  In January 2021, the PTAB issued its decision to institute IPR proceedings for the ‘444 Patent and the ‘474 Patent.  An oral hearing was held on November 1, 2021 and final decisions from the PTAB on the ‘474 Patent and the ‘444 Patent were issued in January 2022. The PTAB ruled against us with respect to the single challenged claim of the ‘444 Patent and ruled in our favor with respect to the seven challenged claims of the ‘474 Patent.  The ‘444 Patent has subsequently been excluded from the narrowed claims asserted in ParkerVision v. Intel.  In July 2022, we appealed the PTAB decision on the '444 Patent to the Federal Circuit.

Table of Contents

In July 2021, the PTAB issued its decision to institute IPR proceedings for the ‘108 Patent.  We filed our response to this petition in October 2021 and an oral hearing was scheduled for April 2022.  A final decision from the PTAB was issued in June 2022 in which the PTAB ruled against us with respect to all of the challenged claims of the '108 Patent.  We filed a notice of appeal with the Federal Circuit with respect to this IPR decision.  Following the parties' resolution of outstanding disputes (see ParkerVision v. Intel above), Intel withdrew as a party to these appeals.

Additional Patent Infringement Cases – Western District of Texas

ParkerVision filed a number of additional patent cases in the Western District of Texas in 2020 including cases against (i) TCL Industries Holdings Co., Ltd, a Chinese company, TCL Electronics Holdings Ltd., Shenzhen TCL New Technology Co., Ltd, TCL King Electrical Appliances (Huizhou) Co., Ltd., TCL Moka Int’l Ltd. and TCL Moka Manufacturing S.A. DE C.V. (collectively “TCL”), (ii) Hisense Co., Ltd. and Hisense Visual Technology Co., Ltd (collectively “Hisense”), a Chinese company, (iii) Buffalo Inc., a Japanese company (“Buffalo”) and (iv) Zyxel Communications Corporation, a Chinese multinational electronics company headquartered in Taiwan, (“Zyxel”).  Each case alleged infringement of the same ten patents by products that incorporate modules containing certain WiFi semiconductors manufactured by Realtek and/or MediaTek.  In May 2021, a case alleging infringement of the same ten patents was filed against LG Electronics, a South Korean company ("LGE").  Each of the defendants have filed responses denying infringement and claiming invalidity of the patents, among other defenses.  A second case was filed against Hisense in June 2021 alleging infringement of two additional patents and a second case was filed against TCL in November 2022 alleging infringement of the same two additional patents.  In November 2022, patent infringement actions were also filed against Taiwanese companies, Realtek Semiconductor Corp. ("Realtek") and MediaTek Inc. and MediaTek USA Inc. (collectively, "MediaTek") for infringement of four U.S. patents that are included in the other Texas cases.

We dismissed the actions against Buffalo and Zyxel in 2021 following satisfaction of the parties' obligations under patent license and settlement agreements.  In November 2022, we dismissed the two cases against Hisense following satisfaction of the parties' obligations under a patent license and settlement agreement.

The court has issued claim construction recommendations for the TCL and LGE cases, in which nearly all of the claim terms were decided in our favor.  In November 2022, the PTAB issued its written decision in two IPRs asserted by TCL and LGE against two of the patents asserted against them (see TCL, et. al. v. ParkerVision (PTAB) below).  The PTAB ruled that the challenged claims of both patents were unpatentable.  We intend to appeal this decision. 

In January 2023, the cases against TCL were stayed pending final resolution of the Realtek case that was filed in November 2022.  In addition, in February 2023, the case against LGE was stayed pending final resolution of the cases against Realtek and MediaTek and the outstanding IPR actions to which LGE is a party.

TCL, et. al. v. ParkerVision (PTAB)

In May 2021, TCL, along with Hisense, filed IPR petitions against U.S. patent 7,292,835 (“the ‘835 Patent”) and the ‘444 Patent, both of which are asserted in the infringement cases against these parties in the Western District of Texas.  In November 2021, the PTAB issued its decision to implement IPR proceedings for these two patents.  In December 2021, LGE filed nearly identical petitions against the same two patents along with a joinder motion requesting to join the existing petitions filed by TCL and Hisense.  In April 2022, the PTAB granted LGE's joinder motion.  Oral hearings for these IPRs were held in September 2022.  As part of a patent license and settlement agreement entered into with Hisense in November 2022, Hisense withdrew its participation in these IPR proceedings.  In November 2022, the PTAB issued its written decision ruling that the challenged claims for both patents were unpatentable.  We intend to appeal this decision.

We have 15 million shares of preferred stock authorized for issuance at the direction of our board of directors (the “Board”).  On November 17, 2005, our Board designated 0.1 million shares of authorized preferred stock as the Series E Preferred Stock in conjunction with its adoption of a Shareholder Protection Rights Agreement.  As of December 31, 2022, we had no outstanding preferred stock.

Common Stock

We have 175 million shares of common stock authorized for issuance as of December 31, 2022.  Our shareholders approved amendments to our articles of incorporation in September 2021 increasing the number of our authorized shares of common stock from 140 million to 150 million shares and in September 2022 increasing the number of our authorized shares of common stock from 150 million to 175 million shares.

Private Placements

In January 2021, we entered into securities purchase agreements with accredited investors for the sale of an aggregate of 2,976,430 shares of our common stock at a price of $0.35 per share for aggregate proceeds of $1.0 million. The securities purchase agreements include contingent payment rights. Approximately $0.4 million of the proceeds were allocated to unsecured contingent payment obligations based on the initial fair value estimate of the CPRs (see “Unsecured Contingent Payment Obligations” in Note 10). The shares were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217).

In March 2021, we entered into securities purchase agreements with accredited investors for the sale of 3,230,942 shares of our common stock and 1,619,289 warrants at a price of $1.29 per common share for aggregate proceeds of approximately $4.2 million. The warrants have an exercise price of $1.75 per share and expire in March 2026. The shares, including the shares underlying the warrants, were registered for resale on a registration statement that was declared effective on April 26, 2021 (File No. 333-255217). We used $3.0 million of the proceeds from this transaction to satisfy outstanding obligations for patent enforcement legal fees and expenses.

In December 2021, we entered into a securities purchase agreement with an accredited investor for the sale of 1,052,631 shares of our common stock and 526,315 warrants at a price of $0.95 per common share for aggregate proceeds of $1.0 million. The warrants have an exercise price of $1.00 per share and expire in December 2026. The shares, including the shares underlying the warrants, were registered for resale on a registration statement that was declared effective on January 24, 2022 (File No. 333-262147).

In November and December 2022, we entered into securities purchase agreements with accredited investors for the sale of 2,000,000 shares of our common stock at a price of $0.20 per share for aggregate proceeds of $0.4 million.  We also entered into a registration rights agreement with the investors pursuant to which we will register the shares underlying the notes.  We have committed to file the registration statement by April 7, 2023 and to cause the registration statement to become effective by April 30, 2023 (or in the event of a review by the Securities and Exchange Commission, by June 30, 2023).  The registration rights agreements provide for liquidated damages upon the occurrence of certain events including failure by us to file the registration statement or cause it to become effective by the deadlines set forth above.  The amount of the liquidated damages is 1.0% of the aggregate subscription upon the occurrence of the event, and monthly thereafter, up to a maximum of 6%, or approximately $0.02 million.

Stock and Warrant Issuances – Payment for Services

In October 2022, we entered into an agreement with Tailwinds Research Group LLC (“Tailwinds”) to provide continuing digital marketing services to us through December 2024.  As consideration for services to be provided under the term of the agreement, we extended the expiration date for warrants previously issued to Tailwinds in 2020 under a prior services agreement.  The warrants allow for the purchase of up to 200,000 shares of our common stock at an exercise price of $1.00 per share and the expiration date was extended from March 2023 to March 2026.  The fair value of the modification of the warrants was valued at approximately $0.02 million using the Black-Scholes method and will be recognized as expense over the term of the new agreement.

Table of Contents

On May 22, 2020, we entered into an agreement with Intro-Act to provide research and shareholder relations services.  As consideration for services under the agreement, we issued 50,000 shares of unregistered common stock on each of July 14, 2020, October 30, 2020, January 12, 2021 and April 6, 2021 with an aggregate value of approximately $0.05 million for the year ended December 31, 2021 and $0.1 million for the year ended December 31, 2022.  In June 2021, we extended our agreement with Intro-Act and issued 100,000 shares of unregistered common stock valued at approximately $0.12 million as consideration for services to be provided over the twelve-month extended term of the agreement.  In August 2022, we again extended our agreement with Intro-Act and issued 150,000 shares of unregistered common stock valued at approximately $0.03 million as consideration for services to be provided over the six-month extended term of the agreement.  The value of the shares was recognized as consulting expense over the term of the agreements.  We are not obligated to register the shares for resale.

On October 30, 2020, we entered into a consulting services agreement with a third-party to provide shareholder relations services.  As consideration for services provided under the twelve-month term of the agreement, we issued 70,000 shares of unregistered common stock for a non-refundable retainer for services valued at approximately $0.02 million.  The agreement included a CPR to receive up to $0.02 million from patent-related proceeds. The CPR was recorded as debt at its estimated fair value of approximately $0.1 million (see “Unsecured Contingent Payment Obligations” in Note 10).  In April 2021, we amended the consulting services agreement and extended the term through December 31, 2021.  We issued 35,000 shares of our unregistered common stock valued at approximately $0.04 million as compensation over the remaining term of the agreement.  The value of the shares issued was recognized as consulting expense over the term of the agreement.  

On November 22, 2022, we entered into an agreement with a third party to provide consulting services.  As consideration for services provided under the twelve-month term of the agreement, we issued non-plan options to purchase 200,000 shares of unregistered common stock at an exercise price of $0.21 per share valued at approximately $0.03 million.  The options vest in four equal three-month increments beginning November 22, 2022 and will expire three years from the date of the grant.  The value of the stock issued will be recognized as a consulting expense over the term of the agreement.  We have agreed to register the shares underlying the option.

In addition, from time to time, we issue restricted stock awards under our approved equity plans to third party consultants as share-based compensation.  During the year ended December 31, 2021, we issued 217,143 RSAs valued at $0.3 million under our 2019 long-term incentive equity plan to non-employees as compensation under consulting agreements (see Note 15).

Common Stock Warrants

We had outstanding warrants for the purchase of up to 10.3 million shares of our common stock as of December 31, 2022 and 2021.  The estimated grant date fair value of these warrants of $3.2 million and is included in shareholders’ deficit in our consolidated balance sheets.  As of December 31, 2022, our outstanding warrants have an average exercise price of $0.75 per share and a weighted average remaining life of approximately 2.1 years.

Shareholder Protection Rights Agreement

On November 20, 2020, we adopted a second amendment to our Shareholder Protection Rights Agreement (“Rights Agreement”) dated November 21, 2005, as amended.  The amendment extends the expiration date of the Rights Agreement from November 20, 2020 to November 20, 2023 and decreases the exercise price of the rights from $14.50 to $8.54.

The Rights Agreement provided for the issuance, on November 29, 2005, as a dividend, rights to acquire fractional shares of Series E Preferred Stock. We did not assign any value to the dividend, as the value of these rights is not believed to be objectively determinable. The principal objective of the Rights Agreement is to cause someone interested in acquiring us to negotiate with our Board rather than launch an unsolicited or hostile bid. The Rights Agreement subjects a potential acquirer to substantial voting and economic dilution. Each share of common stock issued by ParkerVision will include an attached right.

50

Table of Contents

The rights initially are not exercisable and trade with the common stock of ParkerVision. In the future, the rights may become exchangeable for shares of Series E Preferred Stock with various provisions that may discourage a takeover bid. Additionally, the rights have what are known as “flip-in” and “flip-over” provisions that could make any acquisition of us more costly to the potential acquirer. The rights may separate from the common stock following the acquisition of 15% or more of the outstanding shares of common stock by an acquiring person. Upon separation, the holder of the rights may exercise their right at an exercise price of $8.54 per right (the “Exercise Price”), subject to adjustment and payable in cash. Upon payment of the Exercise Price, the holder of the right will receive from us that number of shares of common stock having an aggregate market price equal to twice the Exercise Price, as adjusted. The Rights Agreement also has a flip over provision allowing the holder to purchase that number of shares of common/voting equity of a successor entity, if we are not the surviving corporation in a business combination, at an aggregate market price equal to twice the Exercise Price. We have the right to substitute for any of our shares of common stock that we are obligated to issue, shares of Series E Preferred Stock at a ratio of one ten-thousandth of a share of Series E Preferred Stock for each share of common stock. The Series E Preferred Stock, if and when issued, will have quarterly cumulative dividend rights payable when and as declared by the Board, liquidation, dissolution and winding up preferences, voting rights and will rank junior to other securities of ParkerVision unless otherwise determined by the Board. The rights may be redeemed upon approval of the Board at a redemption price of $0.01.  As of December 31, 2022, there are no Series E preferred shares outstanding.

15. SHARE-BASED COMPENSATION

For the years ended December 31, 2022 and 2021 we recognized share-based compensation expense of approximately $3.1 million and $3.3 million, respectively.  Share-based compensation is included in selling, general, and administrative expenses in our consolidated statements of comprehensive loss.  From time to time, we issue fully vested share-based compensation awards to third parties as prepaid retainers for services over a specified period.  The cost of these awards is recorded as a prepaid asset and expensed to selling, general and administrative expense over the service period (see Note 4).

As of December 31, 2022, there was $0.2 million of total unrecognized compensation cost related to all non-vested share-based compensation awards.  That cost is expected to be recognized over a weighted-average period of approximately 1.3 years.

Stock Incentive Plans

2019 Long-Term Incentive Equity Plan

We adopted a long-term incentive equity plan in August 2019 that, as amended in January 2021, provides for the grant of stock-based awards to employees, officers, directors, and consultants, not to exceed 27.0 million shares of common stock (the “2019 Plan”).  The 2019 Plan provides for benefits in the form of nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock-based awards.  Forfeited and expired options under the 2019 Plan become available for reissuance.  The plan provides that non-employee directors may not be granted awards during any calendar year that exceed the lesser of 1.0 million shares or $175,000 in value, calculated based on grant-date fair value.  At December 31, 2022, 281,467 shares of common stock were available for future grants under the 2019 Plan.  The 2019 Plan was amended in January 2023 (see Note 18).

2011 Long-Term Incentive Equity Plan

We adopted a long-term incentive equity plan in September 2011 that, as amended in 2014, 2016 and 2017, provides for the grant of stock-based awards to employees, officers, directors and consultants, not to exceed 3.0 million shares of common stock (the “2011 Plan”).  The 2011 Plan provides for benefits in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock-based awards.  Forfeited and expired options under the 2011 Plan become available for reissuance.  The plan provides that no participant may be granted awards in excess of 150,000 shares in any calendar year.  At December 31, 2022, 61,302 shares of common stock were available for future grants under the 2011 Plan. In January 2023, we ceased any future grants under the 2011 Plan.

Table of Contents

2008 Equity Incentive Plan

We adopted an equity incentive plan in August 2008 (the “2008 Plan”). The 2008 Plan provides for the grant of stock-based awards to employees (excluding named executives), directors and consultants, not to exceed 50,000 shares of common stock. The 2008 Plan provides for benefits in the form of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, and other stock-based awards. Forfeited and expired options under the 2008 Plan become available for reissuance. The plan provides that no participant may be granted awards in excess of 5,000 shares in any calendar year.  At December 31, 2022, 20,473 shares of common stock were available for future grants under the 2008 Plan.  In January 2023, the 2008 Plan was terminated.

Restricted Stock Awards

RSAs are issued as executive and employee incentive compensation and as payment for services to others.  The value of the award is based on the closing price of our common stock on the date of grant.  RSAs are generally immediately vested.

Restricted Stock Units

RSUs are issued as incentive compensation to executives, employees, and non-employee directors.  Each RSU represents a right to one share of our common stock, upon vesting.  The RSUs are not entitled to voting rights or dividends, if any, until vested.  RSUs generally vest over a one to three year period for employee awards and a one year period for non-employee director awards.  The fair value of RSUs is generally based on the closing price of our common stock on the date of grant and is amortized to share-based compensation expense over the estimated life of the award, generally the vesting period.

RSAs and RSUs

The following table presents a summary of RSA and RSU activity under the 2008, 2011, and 2019 Plans (collectively, the “Stock Plans”) as of December 31, 2022 (shares in thousands):

	Non-vested Shares
	Shares			Weighted-Average Grant Date Fair Value
Non-vested at beginning of year		-
Granted		166			0.18
Vested		(166	)		0.18
Forfeited		-			-
Non-vested at end of year		-		$	-

The total fair value of RSAs and RSUs vested under the Stock Plans for the years ended December 31, 2022 and 2021 was approximately $0.03 million and $0.6 million, respectively.

Table of Contents

Stock Options

Stock options are issued as incentive compensation to executives, employees, consultants and non-employee directors.  Stock options are generally granted with exercise prices at or above fair market value of the underlying shares at the date of grant.  Fair market value of the underlying shares is determined based on observable market prices at the date of the grant.  The fair value of options granted is estimated using the Black-Scholes option pricing model.  Generally, fair value is determined as of the grant date.  Options for employees, including executives and non-employee directors, are generally granted under the Stock Plans.

The following table presents a summary of option activity under the Stock Plans for the year ended December 31, 2022 (shares in thousands):

	Shares			Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value ($)
Outstanding at beginning of year		23,215		$	0.42
Granted		1,450			0.19
Exercised		(485	)		0.17
Forfeited/Expired		-			-
Outstanding at end of year		24,180			0.41		3.6	$	542
Vested at end of year		22,943		$	0.42		3.3	$	489

The weighted average per share fair value of options granted during the years ended December 31, 2022 and 2021 was $0.17 and $0.46, respectively.  The total fair value of option shares vested was $3.0 million and $3.4 million for the year ended December 31, 2022 and 2021, respectively.

The fair value of option grants under the Stock Plans for the years ended December 31, 2022 and 2021, respectively, was estimated using the Black-Scholes option-pricing model with the following assumptions:

	2022	2021
Expected option term (in years) 1	5	4
Expected volatility factor 2	143.9 - 155.9%	141.1%
Risk-free interest rate 3	3.05 - 4.09%	0.36%
Expected annual dividend yield	0%	0%

1 The expected term was generally determined based on historical activity for grants with similar terms and for similar groups of employees and represents the period of time that options are expected to be outstanding.  For employee options, groups of employees with similar historical exercise behavior are considered separately for valuation purposes.

2 The stock volatility for each grant is measured using the weighted average of historical daily price changes of our common stock over the most recent period equal to the expected option life of the grant.

3 The risk-free interest rate for periods equal to the expected term of the share option is based on the U.S. Treasury yield curve in effect at the measurement date.

Options by Price Range

The options outstanding at December 31, 2022 under the Stock Plans have exercise price ranges, weighted average contractual lives, and weighted average exercise prices as follows (weighted average lives in years and shares in thousands):

	Options Outstanding						Options Vested
Range of Exercise Prices	Number Outstanding at December 31, 2022		Wtd. Avg. Exercise Price		Wtd. Avg. Remaining Contractual Life		Number Exercisable at December 31, 2022		Wtd. Avg. Exercise Price		Wtd. Avg. Remaining Contractual Life
$0.171 - $0.33		10,254	$	0.18		4.5		9,017	$	0.18		3.7
$0.50 - $0.75		13,553		0.54		3.0		13,553		0.54		3.0
$1.98 - $2.97		373		2.02		1.5		373		2.02		1.5
		24,180	$	0.41		3.6		22,943	$	0.42		3.3

We issue new shares of our common stock upon exercise of options or vesting of RSUs or RSAs under the Stock Plans.  The shares underlying the Stock Plans are registered.  Cash received from option exercises for the years ended December 31, 2022 and 2021, was $0.1 million and $0.3. million, respectively.

17. CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject us to a concentration of credit risk principally consist of cash and cash equivalents. Cash and cash equivalents are primarily held in bank accounts and overnight investments. At times our cash balances on deposit with banks may exceed the balance insured by the F.D.I.C.

18. SUBSEQUENT EVENTS

In February 2023, we entered into a confidential patent license and settlement agreement and in March 2023, we received a payment of $25 million with respect thereto.

In February 2023, we dismissed our two patent enforcement actions against Intel Corporation (see Note 13).

In January 2023, we received aggregate proceeds of approximately $0.7 million from the sale of convertible notes to accredited investors.  The notes mature five years from the date of issuance and are convertible, at the holders' option, into shares of our common stock at a fixed conversion price of $0.16 per share, except that the maturity date of $0.5 million of the notes may be extended for up to ten (10) one-year periods at the option of the holder.  The notes bear interest at a stated rate of 9% per annum.  Interest is payable quarterly, and we may elect, subject to certain equity conditions, to pay interest in cash, shares of our common stock, or a combination thereof.  In January 2023, we received aggregate proceeds of approximately $0.14 million from the sale of common stock to accredited investors at a price of $0.16 per share.  We entered into registration rights agreements with the investors pursuant to which we will register the shares.  We have committed to file the registration statement by April 7, 2023 and to cause the registration statement to become effective by April 30, 2023 (or in the event of a review by the Securities and Exchange Commission, by June 30, 2023).  The registration rights agreements provide for liquidated damages upon the occurrence of certain events including failure by us to file the registration statement or cause it to become effective by the deadlines set forth above.  The amount of the liquidated damages is 1.0% of the aggregate subscription upon the occurrence of the event, and monthly thereafter, up to a maximum of 6%, or approximately $0.05 million.

On January 16, 2023, the Board amended the 2019 Long-Term Incentive Plan to increase the number of shares of common stock reserved for issuance under the 2019 Plan from 27 million shares to 30 million shares.

Evaluation of Disclosure Controls and Procedures

Under Rules 13a-15(e) and 15d-15(e) of the Exchange Act, “disclosure controls and procedures” are controls and other procedures that are designed to ensure that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified under the rules and forms of the SEC.  Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding required disclosures.  Our management, with the participation of our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022.  Based on such evaluation, our chief executive officer and our chief financial officer have concluded that as of December 31, 2022, our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting.  Under Rules 13a-15(f) and 15d-15(f) of the Exchange Act, “internal control over financial reporting’’ is defined as a process designed by, or under the supervision of, our chief executive officer and our chief financial officer, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting includes policies and procedures that pertain to the maintenance of records, that in reasonable detail, accurately and fairly reflect our transactions and our dispositions of assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting; provide reasonable assurance that receipts and expenditures of the Company are made only in accordance with authorizations of management and directors; and provide reasonable assurance regarding the prevention or the timely detection of the unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management, with the participation of our chief executive officer and our chief financial officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2022 using the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.  Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2022.

The following table summarizes the total compensation of each of our “named executive officers” as defined in Item 402(m) of Regulation S-K (the “Executives”) for the fiscal years ended December 31, 2022 and 2021.  Given the complexity of disclosure requirements concerning executive compensation, and in particular with respect to the standards of financial accounting and reporting related to equity compensation, there is a difference between the compensation that is reported in this table versus that which is actually paid to and received by the Executives.  The amounts in the Summary Compensation Table that reflect the full grant date fair value of an equity award, do not necessarily correspond to the actual value that has been realized or will be realized in the future with respect to these awards.

In July 2022, the Board approved a performance bonus for Ms. French that included $20,000 cash and 166,390 immediately vested shares of our common stock in consideration for the substantial savings in outside professional fees Ms. French has enabled by bringing significant activities in-house.

Item 13. Certain Relationships and Related Transactions and Director Independence.

Related Party Transactions

We paid approximately $7,000 and $97,000 in 2022 and 2021, respectively for patent-related legal services to SKGF, of which Robert Sterne is a partner.  In addition, we paid approximately $115,000 and $130,000 in 2022 and 2021, respectively, for principal and interest on an unsecured note payable to SKGF.  The note was issued in 2016 to convert outstanding unpaid legal fees to an unsecured promissory note.  The note has been amended multiple times to defer principal payments.  The note, as amended, allows for interest at 4% per annum, monthly installments of $12,500 per month beginning October 2022, with a final balloon payment due on April 30, 2027.  At December 31, 2022, the outstanding balance of the note, including unpaid interest is approximately $612,000.

In May 2022, we sold an aggregate of $100,000 in promissory notes, convertible into shares of our common stock at a fixed conversion price of $0.13 to Paul Rosenbaum, one of our directors since December 2016.  In August 2022, we sold an aggregate of $25,000 in promissory notes, convertible into shares of our common stock at a fixed conversion price of $0.13 to Sanford Litvack, who became an independent director in October 2022.

Director Independence

We follow the rules of Nasdaq in determining if a director is independent.  The Board also consults with our counsel to ensure that the Board’s determination is consistent with those rules and all relevant securities and other laws and regulations regarding the independence of directors.  The Board has affirmatively determined that Messrs. Litvack, Newman, Rosenbaum, and Sterne are independent directors.
