1.  DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business. As used herein, “Acacia” and the “Company” refer to Acacia Research Corporation and/or its wholly and majority-owned and controlled operating subsidiaries, and/or where applicable, its management.  All patent investment, prosecution, licensing and enforcement activities are conducted solely by certain of Acacia’s wholly and majority-owned and controlled operating subsidiaries.

Acacia’s operating subsidiaries invest in, license and enforce patented technologies. Acacia’s operating subsidiaries partner with inventors and patent owners, applying their legal and technology expertise to patent assets to unlock the financial value in their patented inventions. Acacia is an intermediary in the patent marketplace, bridging the gap between invention and application, facilitating efficiency and delivering monetary rewards to patent owners.

Acacia’s operating subsidiaries generate revenues and related cash flows from the granting of intellectual property rights for the use of patented technologies that its operating subsidiaries control or own. Acacia’s operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, where necessary, with the enforcement against unauthorized users of their patented technologies through the filing of patent infringement litigation.

Acacia’s operating subsidiaries are principals in the licensing and enforcement effort, obtaining control of the rights in the patent portfolio, or control of the patent portfolio outright. Acacia’s operating subsidiaries own or control the rights to multiple patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.

Basis of Presentation.  The accompanying consolidated financial statements include the accounts of Acacia and its wholly and majority-owned and controlled subsidiaries. Material intercompany transactions and balances have been eliminated in consolidation. Noncontrolling interests in Acacia’s majority-owned and controlled operating subsidiaries (“noncontrolling interests”) are separately presented as a component of stockholders’ equity in the consolidated statements of financial position for the applicable periods presented. Consolidated net income (loss) is adjusted to include the net (income) loss attributed to noncontrolling interests in the consolidated statements of operations. Refer to the accompanying consolidated financial statements for total noncontrolling interests, net (income) loss attributable to noncontrolling interests and contributions from and distributions to noncontrolling interests, for the applicable periods presented.

A wholly owned subsidiary of Acacia is the general partner of the Acacia Intellectual Property Fund, L.P. (the “Acacia IP Fund”), which was formed in August 2010. The Acacia IP Fund is included in the Company’s consolidated financial statements for the periods presented because Acacia’s wholly owned subsidiary, which is the majority owner and general partner, has the ability to control the operations and activities of the Acacia IP Fund.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, certain information and footnotes required by accounting principles generally accepted in the United States of America in annual financial statements have been omitted or condensed in accordance with quarterly reporting requirements of the Securities and Exchange Commission (“SEC”).  These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2014, as reported by Acacia in its Annual Report on Form 10-K filed with the SEC.  The year end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America.

The condensed consolidated interim financial statements of Acacia include all adjustments of a normal recurring nature which, in the opinion of management, are necessary for a fair statement of Acacia’s consolidated financial position as of June 30, 2015, and results of its operations and its cash flows for the interim periods presented.  The consolidated results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the entire fiscal year.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition.  Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been substantially performed pursuant to the terms of the arrangement, (iii) amounts are fixed or determinable, and (iv) the collectibility of amounts is reasonably assured.

In general, revenue arrangements provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by Acacia’s operating subsidiaries.  These rights typically include some combination of the following:  (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by Acacia’s operating subsidiaries, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and (iv) the dismissal of any pending litigation.  The intellectual property rights granted may be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment.  Pursuant to the terms of these agreements, Acacia’s operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on Acacia’s operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverables upon execution of the agreement, or upon receipt of the minimum upfront payment for term agreement renewals.  As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, when collectibility is reasonably assured, or upon receipt of the minimum upfront fee for term agreement renewals, and when all other revenue recognition criteria have been met.

For the periods presented herein, the majority of the revenue agreements executed by the Company provided for the payment of one-time, paid-up license fees in consideration for the grant of certain intellectual property rights for patented technology rights owned by our operating subsidiaries. These rights were primarily granted on a perpetual basis, extending until the expiration of the underlying patents.

Cost of Revenues.  Cost of revenues include the costs and expenses incurred in connection with Acacia’s patent licensing and enforcement activities, including inventor royalties paid to original patent owners, contingent legal fees paid to external patent counsel, other patent-related legal expenses paid to external patent counsel, licensing and enforcement related research, consulting and other expenses paid to third-parties and the amortization of patent-related investment costs.  These costs are included under the caption “Cost of revenues” in the accompanying consolidated statements of operations.  

Inventor Royalties and Contingent Legal Expenses. Inventor royalties are expensed in the consolidated statements of operations in the period that the related revenues are recognized.  In certain instances, pursuant to the terms of the underlying inventor agreements, upfront advances paid to patent owners by Acacia’s operating subsidiaries are recoverable from future net revenues.  Patent costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statements of operations.  Any unamortized upfront advances recovered from net revenues are expensed in the period recovered, and included in amortization expense in the consolidated statements of operations.

Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, Acacia’s operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.  

Use of Estimates.  The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, stock-based compensation expense, impairment of marketable securities and intangible assets including goodwill, the determination of the economic useful life of amortizable intangible assets, income taxes and valuation allowances against net deferred tax assets and the application of the acquisition method of accounting for business combinations, require its most difficult, subjective or complex judgments.

Concentrations. One licensee individually accounted for 74% of revenues recognized during the three months ended June 30, 2015, and two licensees accounted for 40% and 27% of revenues recognized during the six months ended June 30, 2015. Two licensees individually accounted for 58% and 14% of revenues recognized during the three months ended June 30, 2014, and two licensees accounted for 46% and 11% of revenues recognized during the six months ended June 30, 2014.

One licensee individually represented approximately 80% of accounts receivable at June 30, 2015. The majority of accounts receivable balances at June 30, 2015 were collected in July 2015. Three licensees individually represented approximately 30%, 17% and 15% of accounts receivable at December 31, 2014. For the three and six months ended June 30, 2015, 18% and 38%, respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions, based on the jurisdiction of the entity obligated to satisfy payment obligations pursuant to the applicable revenue arrangement. For the three and six months ended June 30, 2014, 79% and 67%, respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions. The Company does not have any material foreign operations.

Stock-Based Compensation. The compensation cost for stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (the vesting period of the equity award) which is two to four years. The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units granted and the grant date market price of the underlying common stock. Stock-based compensation expense is recorded only for those awards expected to vest using an estimated forfeiture rate.

Fair Value Measurements. U.S. GAAP defines fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established to measure fair value is defined as follows:

● Level 1 - Observable Inputs:  Quoted prices in active markets for identical investments;

● Level 2 - Pricing Models with Significant Observable Inputs:  Other significant observable inputs, including quoted prices for similar investments, interest rates, credit risk, etc.; and

● Level 3 - Unobservable Inputs:  Significant unobservable inputs, including the entity’s own assumptions in determining the fair value of investments.

 Whenever possible, the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value.

Investments in Marketable Securities. Investments in securities with original maturities of greater than three months and less than one year and other investments representing amounts that are available for current operations are classified as short-term investments, unless there are indications that such investments may not be readily sold in the short term. The fair values of these investments approximate their carrying values. For the periods presented, all of Acacia’s short term investments were classified as available-for-sale, which are reported at fair value on a recurring basis using observable inputs (Level 1), with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders’ equity until realized. Realized and unrealized gains and losses are recorded based on the specific identification method. Interest on all securities is included in interest income.

Short-term marketable securities for the periods presented were comprised of the following (in thousands):

	June 30, 2015
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities	$	37,270	$	10	$	(190	)	$	37,090
Total short-term investments	$	37,270	$	10	$	(190	)	$	37,090

ACACIA RESEARCH CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

	December 31, 2014
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities	$	58,819	$	2	$	(263	)	$	58,558
Total short-term investments	$	58,819	$	2	$	(263	)	$	58,558

The gross unrealized loss can be primarily attributed to a combination of market conditions as well as the demand for and duration of the U.S. government fixed income securities. The Company has the ability to hold these securities until maturity, currently has no intent to sell, there is no requirement to sell and the Company believes that it can recover the amortized cost of these investments. The Company has found no evidence of impairment due to credit losses in its portfolio. Therefore, these unrealized losses were recorded in other comprehensive income (loss). However, the Company cannot provide any assurance that its portfolio of short-term marketable securities will not be impacted by adverse conditions in the financial markets, which may require the Company in the future to record an impairment charge for credit losses which could adversely impact its financial results.

Patents.  Patents include the cost of patents or patent rights (hereinafter, collectively “patents”) obtained from third-parties or obtained in connection with business combinations. Capitalized patent costs are amortized utilizing the straight-line method over their remaining economic useful lives, ranging from one to nine years. Certain patent application and prosecution costs incurred to secure additional patent claims, that based on management’s estimates are deemed to be recoverable, are capitalized and amortized over the remaining estimated economic useful life of the related patent portfolio.

Goodwill. Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (December 31) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Acacia considers its market capitalization and other valuation techniques and the carrying value of its assets and liabilities, including goodwill, when performing its goodwill impairment test. When conducting its annual goodwill impairment assessment, the Company initially performs a qualitative evaluation of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, the Company then applies a two-step impairment test. The two-step impairment test first compares the fair value of the Company’s reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, the Company determines the implied fair value of the reporting unit’s goodwill and if the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations. Refer to Note 9 for additional information.

Impairment of Long-lived Assets. Acacia reviews long-lived assets and intangible assets for potential impairment annually (quarterly for patents) and when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss is recorded equal to the excess of the asset’s carrying value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available or not indicative of current fair value, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows.

Fair value is generally estimated using the “Income Approach,” focusing on the estimated future net income-producing capability of the patent portfolios over the estimated remaining economic useful life. Estimates of future after-tax cash flows are converted to present value through “discounting,” including an estimated rate of return that accounts for both the time value of money and investment risk factors. Estimated cash inflows are typically based on estimates of reasonable royalty rates for the applicable technology, applied to estimated market data. Estimated cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio’s licensing and enforcement program. The analysis also contemplates consideration of current information about the patent portfolio including, status and stage of litigation, periodic results of the litigation process, technology coverage and other pertinent information that could impact future net cash flows.

Income Taxes.  Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in Acacia’s

consolidated financial statements or consolidated income tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized, or if it is determined that there is uncertainty regarding future realizability of such assets.

The provision for income taxes for interim periods is determined using an estimate of Acacia’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, Acacia updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, a cumulative adjustment is recorded.  

The Company's effective tax rates were 13% and 2% for the three and six months ended June 30, 2015, respectively, and 56% and 10% for the three and six months ended June 30, 2014. The effective rates for the periods presented primarily reflect the impact of foreign withholding taxes related to certain revenue agreements executed with third party licensees domiciled in foreign jurisdictions, and valuation allowances recorded for foreign withholding tax credits and net operating loss related tax assets generated during the periods.

3.  INCOME (LOSS) PER SHARE

The Company computes net income (loss) attributable to common stockholders using the two-class method required for capital structures that include participating securities. Under the two-class method, securities that participate in non-forfeitable dividends, such as the Company’s outstanding unvested restricted stock, are considered “participating securities.”

In applying the two-class method, (i) basic net income (loss) per share is computed by dividing net income (loss) (less any dividends paid on participating securities) by the weighted average number of shares of common stock and participating securities outstanding for the period and (ii) diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying the two-class method and the treasury stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options, and restricted stock units for calculations utilizing the two-class method, and also include unvested restricted stock, when utilizing the treasury method.

The following table presents the weighted-average number of common shares outstanding used in the calculation of basic and diluted income (loss) per share:

4.  PATENTS

Acacia’s only identifiable intangible assets at June 30, 2015 and December 31, 2014 are patents and patent rights.  Patent-related accumulated amortization totaled $192,831,000 and $166,565,000 as of June 30, 2015 and December 31, 2014, respectively.

Acacia’s patents have remaining estimated economic useful lives ranging from one to nine years.  The weighted-average remaining estimated economic useful life of Acacia’s patents is approximately six years.  The following table presents the scheduled annual aggregate amortization expense as of June 30, 2015 (in thousands):

For the years ending December 31,
Remainder of 2015	$	26,080
2016	49,765
2017	48,676
2018	44,549
2019	38,917
Thereafter	54,350
	$	262,337

For the six months ended June 30, 2015 and 2014, Acacia paid patent related investment costs, including up-front patent portfolio advances and previously accrued milestone payments related to patent related investments made in prior periods, totaling $18,667,000 and $22,096,000, respectively.  The underlying patents have estimated economic useful lives of approximately four to ten years. Included in net additions to capitalized patent costs during the six months ended June 30, 2014 are accrued patent investment costs totaling $3,000,000 which are amortized over the estimated economic useful life of the related patents.

During the six months ended June 30, 2014, certain Acacia operating subsidiaries elected to sell their rights to patent portfolios, resulting in the acceleration of amortization expense for the patent-related assets totaling $2,702,000. Proceeds from the sale of patents and the related gain on sale for the six months ended June 30, 2014 were $3,500,000 and $833,000, respectively. Included in amortization of patents for the six months ended June 30, 2014 was accelerated amortization related to the partial write-down of a patent portfolio, due to a reduction in expected estimated future net cash flows, totaling $2,565,000.

5.  COMMITMENTS AND CONTINGENCIES

Bank Guarantee

In March 2015, an operating subsidiary of Acacia entered into a standby letter of credit and guarantee arrangement (“Guarantee”) with a bank in the amount of $10,718,000, for purposes of enforcing a court ruling in a German patent court granting an injunction against the defendants in the related patent infringement case. An injunction is an equitable remedy in the form of a court order that compels the defendant(s) to cease marketing, offering for sale or importing applicable infringing products into applicable jurisdiction(s).

Under German law, in order to enforce the injunction granted by the court, a Guarantee is required to be furnished by our operating subsidiary, the plaintiff in the case, for potential payment to the defendants of any applicable claims which may be incurred by the defendants as a result of the enforcement of the injunction, only in the event that the aforementioned court ruling is subsequently successfully appealed by the defendants or otherwise amended. The Guarantee is required to be issued unlimited with respect to time, until appropriately extinguished in accordance with German law. The Guarantee will be extinguished when a relevant extinguishment order by the court having jurisdiction takes effect, typically occurring when the related infringement case has been settled or a final non-appealable decision has been issued by the court.

The Guarantee is secured by a cash deposit at the contracting bank totaling $10,718,000, which is classified as restricted cash in the June 30, 2015 balance sheet. The Guarantee expires on April 10, 2016, however, it is automatically extended without amendment for a period of one (1) year from the present or any future expiration date, unless at least 30 days

10

ACACIA RESEARCH CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

prior to any expiration date, the Guarantee is extinguished in accordance with German law. The Guarantee facility fee is 1.15% per year, and the related expense is included in the consolidated statement of operations.

Patent Enforcement

Certain of Acacia’s operating subsidiaries are often required to engage in litigation to enforce their patents and patent rights.  In connection with any of Acacia’s operating subsidiaries’ patent enforcement actions, it is possible that a defendant may request and/or a court may rule that an operating subsidiary has violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions.  In such event, a court may issue monetary sanctions against Acacia or its operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material.

During the six months ended June 30, 2015, a federal court decided that a lawsuit initiated in 2013 was exceptional. The respective operating subsidiaries have taken steps to challenge the amounts requested including the filing of a notice of appeal. Operating expenses for the six months ended June 30, 2015 included an expense for this matter totaling $426,000.

Other

In February 2011, Michael Strathmann ("Plaintiff") served a Complaint for Violation of the Insurance Fraud Prevention Act (California Insurance Code Section 1871.7) against Acacia, CombiMatrix Corporation, and Dr. Amit Kumar in the Superior Court of the State of California (the "Court") in connection with a prior lawsuit against Nanogen, Inc., that was settled in 2002. Plaintiff alleged that the defendants wrongfully made a claim for insurance coverage for the Nanogen lawsuit leading to a settlement with the insurer. The trial commenced in June 2014. In March 2015, the court issued a final judgment in Acacia's favor, dismissing the complaint with prejudice and affirming its prior rulings in favor of Acacia and the defendants, and against all claims of the Plaintiff.

Acacia is subject to claims, counterclaims and legal actions that arise in the ordinary course of business.  Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on Acacia’s consolidated financial position, results of operations or cash flows.

6. STOCKHOLDERS’ EQUITY

Cash Dividends. On April 23, 2013, Acacia announced that its Board of Directors approved the adoption of a cash dividend policy that calls for the payment of an expected total annual cash dividend of $0.50 per common share, payable in the amount of $0.125 per share per quarter. Under the policy, the Company paid quarterly cash dividends totaling $12,749,000 and $12,513,000 during the six months ended June 30, 2015 and 2014, respectively. Future cash dividends are expected to be paid on a quarterly basis and will be at the discretion of the Company’s Board of Directors.

7. SUBSEQUENT EVENTS

On July 23, 2015, Acacia announced that its Board of Directors approved a quarterly cash dividend payable in the amount of $0.125 per share. The quarterly cash dividend will be paid on August 31, 2015 to stockholders of record at close of business on August 5, 2015. Future cash dividends are expected to be paid on a quarterly basis and will be at the discretion of the Company’s Board of Directors.

8.  RECENT ACCOUNTING PRONOUNCEMENTS

Recent Accounting Pronouncements - Not Yet Adopted.

In June 2014, the Financial Accounting Standards Board (the "FASB") issued a new accounting standard which requires that a performance target that affects vesting and could be achieved after the requisite service period shall be treated as a performance condition. Adoption of this standard is required for annual periods beginning after December 15, 2015. Early adoption is permitted. Management is currently evaluating the impact the pronouncement will have on the Company's consolidated financial statements and related disclosures.

11

ACACIA RESEARCH CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

In May 2014, the FASB issued a new accounting standards update addressing revenue from contracts with customers, which clarifies existing accounting literature relating to how and when a company recognizes revenue.  Under the standard, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services.  The amendments for this standard update are effective for interim and annual reporting periods beginning after December 15, 2016, and are to be applied retrospectively or the cumulative effect as of the date of adoption, with early application not permitted.  On April 1, 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier if they choose (i.e., the original effective date). Management is currently evaluating the impact the pronouncement will have on the Company's consolidated financial statements and related disclosures.

In August 2014, the FASB issued a new accounting standard which requires management to assess an entity’s ability to continue as a going concern every reporting period including interim periods, and to provide related footnote disclosure in certain circumstances. Adoption of this standard is required for annual periods beginning after December 15, 2016 and are to be applied retrospectively or the cumulative effect as of the date of adoption. Early adoption is permitted. Management is currently evaluating the impact the pronouncement will have on the Company's consolidated financial statements and related disclosures.

In April 2015, the FASB issued an accounting standard update to simplify the presentation of debt issuance costs. The amendments in this accounting standard update require debt issuance costs be presented on the balance sheet as a direct reduction from the carrying amount of the related debt liability. The amendments in this accounting standard update are to be applied retrospectively and are effective for interim and annual reporting periods beginning after December 15, 2015. Management is currently evaluating the impact the pronouncement will have on our consolidated financial statements and related disclosures.

9. GOODWILL

Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Factors considered important, which could trigger an impairment review, include the following:

• significant underperformance relative to expected historical or projected future operating results;

• significant changes in the manner of use of the assets or the strategy for Acacia's overall business; 

• significant negative industry or economic trends; 

• significant adverse changes in legal factors or in the business climate, including adverse regulatory actions or assessments; and 

• significant decline in the Company's stock price for a sustained period.

The Company considers its market capitalization and other valuation techniques as applicable, and the carrying value of its assets and liabilities, including goodwill, when performing goodwill impairment tests. When conducting annual and interim goodwill impairment assessments, the Company initially performs a qualitative evaluation (considering factors described above as applicable) of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, the Company then applies a two-step impairment test. The two-step impairment test first compares the fair value of Acacia's reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, then the Company is required to determine the implied fair value of the reporting unit’s goodwill and if the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations.

As of June 30, 2015, the Company assessed the impact of the recent downward volatility in the Company's stock price and concluded that the decline constituted a triggering event requiring an interim goodwill impairment test pursuant to ASC Topic 350, "Intangibles-Goodwill and Other." The Company conducted the first step of the goodwill impairment test described above for its single reporting unit as of June 30, 2015. The fair value of the reporting unit exceeded its carrying value as of June 30, 2015, and therefore goodwill was determined to not be impaired as of June 30, 2015.

Fair value was estimated using the “Income Approach,” as described by ASC 820, “Fair Value Measurements and Disclosures,” focusing on the estimated future income-producing capability of the Company's assets, principally its patent portfolios, to determine the present value of the estimated future net economic benefit (cash receipts less cash outlays). The

12

ACACIA RESEARCH CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

approach included estimates of after-tax cash flows attributable to the Company's aggregate assets and converting these after-tax cash flows to present value through “discounting.” The discounting process contemplated an estimated rate of return that accounts for both the time value of money and investment risk factors. The cash inflows considered were comprised of an estimate of revenues from future licensing. Estimated cash outflows were based on estimated contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to estimated revenues, in addition to other estimates of out-of-pocket expenses associated with licensing and enforcement and ongoing operations. Net cash flows also considered utilization of the Company's applicable tax assets, including net operating loss carryforwards, subject to applicable limitations on use.

General

As used in this Quarterly Report on Form 10-Q, “we,” “us” and “our” refer to Acacia Research Corporation, a Delaware corporation, and/or its wholly and majority-owned and controlled operating subsidiaries, and/or where applicable, its management. All intellectual property acquisition, development, licensing and enforcement activities are conducted solely by certain of Acacia Research Corporation’s wholly and majority-owned and controlled operating subsidiaries.

Our operating subsidiaries invest in, license and enforce patented technologies. Our operating subsidiaries partner with inventors and patent owners, applying our legal and technology expertise to patent assets to unlock the financial value in their patented inventions. We are an intermediary in the patent marketplace, bridging the gap between invention and application, facilitating efficiency and delivering monetary rewards to patent owners.

Our operating subsidiaries generate revenues and related cash flows from the granting of patent rights for the use of patented technologies that our operating subsidiaries control or own. Our operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, where necessary, with the enforcement against unauthorized users of their patented technologies through the filing of patent infringement litigation.

We are a leader in licensing patented technologies and have established a proven track record of licensing success with over 1,475 license agreements executed to date, across 184 patent licensing and enforcement programs. Currently, on a consolidated basis, our operating subsidiaries own or control the rights to multiple patent portfolios, which include U.S. patents

14

and certain foreign counterparts, covering technologies used in a wide variety of industries. To date, we have generated gross licensing revenue of approximately $1.2 billion, and have returned more than $694 million to our patent partners.

Executive Summary

We continued our business of empowering patent owners and rewarding invention by providing a path to patent monetization for the people and companies who have contributed valuable patented inventions to an industry, but who require a professional, experienced independent third-party licensing partner to get rewarded for those inventions. These people and companies are our customers, and in many cases, components of the patent disenfranchised. In so doing, we have placed ourselves at the forefront of an emerging secondary market in patent assets under which holders of high quality patents, including the patent disenfranchised, may be rewarded for the use of their patented inventions by others, even if they do not have the capital and expertise to engage in lengthy, costly and risky patent litigation.

Our operating activities have been principally focused on the continued investment in and development of our patent licensing and enforcement business, including the continued pursuit of our ongoing patent licensing and enforcement programs and the commencement of new patent licensing and enforcement programs. In addition, we continued our focus on business development, including the continued investment in existing portfolios during the 2015 period and in new high quality patent portfolios during the 2014 period by certain of our operating subsidiaries, and the continued pursuit of additional opportunities to partner with patent owners or invest in new patent portfolios and continue our industry leading patent licensing and enforcement activities.

For the three months ended June 30, 2015, we reported revenues of $40.3 million from 20 new revenue agreements covering 18 different licensing programs, including one licensing program generating initial revenues in the quarter. Cash and investments (including restricted cash) totaled $166.9 million as of June 30, 2015 as compared to $193.0 million as of December 31, 2014.

During the three months ended June 30, 2015, we made patent related investment payments to patent owners, with whom we partnered for the licensing of their patented technologies, totaling $1.8 million.

Operating activities during the periods presented included the following:

	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Revenues (in thousands)	$	40,336	$	50,076	$	74,546	$	62,654
New agreements executed	20		15		43		35
Licensing and enforcement programs generating revenues	18		16		25		31
Licensing and enforcement programs with initial revenues	1		4		3		7
New patent portfolios	—		1		—		4

We measure and assess the performance and growth of the patent licensing and enforcement businesses conducted by our operating subsidiaries based on consolidated revenues recognized across all of our technology licensing and enforcement programs on a trailing twelve-month basis.  Trailing twelve-month revenues during the periods presented were as follows (in thousands, except percentage change values):

As of Date:	Trailing Twelve -Month Revenues		% Change
June 30, 2015	$	142,768	(6	)%
March 31, 2015	$	152,508	17	%
December 31, 2014	$	130,876	14	%
September 30, 2014	$	114,911	23	%
June 30, 2014	$	93,239	—	%

15

Our revenues historically have fluctuated quarterly, and can vary significantly, based on a number of factors including the following:

• the dollar amount of agreements executed each period, which can be driven by the nature and characteristics of the technology or technologies being licensed and the magnitude of infringement associated with a specific licensee;

• the specific terms and conditions of agreements executed each period including the nature and characteristics of rights granted, and the periods of infringement or term of use contemplated by the respective payments;

• fluctuations in the total number of agreements executed each period;

• the number of, timing, results and uncertainties associated with patent licensing negotiations, mediations, patent infringement actions, trial dates and other enforcement proceedings relating to our patent licensing and enforcement programs;

• the relative maturity of licensing programs during the applicable periods;

• other external factors, including the periodic status or results of ongoing negotiations, the status or results of ongoing litigations and appeals, actual or perceived shifts in the regulatory environment, impact of unrelated patent related judicial proceedings and other macroeconomic factors; and

• historically, based on the merits and strength of our operating subsidiary’s patent infringement claims and other factors, many prospective licensees have elected to settle significant patent infringement cases and pay reasonable license fees for the use of our patented technology, as those patent infringement cases approached a court determined trial date.

Management does not attempt to manage for smooth sequential periodic growth in revenues period to period, and therefore, periodic results can be uneven. Unlike most operating businesses and industries, licensing revenues not generated in a current period are not necessarily foregone but, most likely, depending on whether negotiations, litigation or both continue into subsequent periods, and depending on a number of other factors, such potential revenues may be pushed into subsequent fiscal periods.

Although revenues from one or more of our patents or patent portfolios may be significant in a specific reporting period, we believe that none of our individual patents or patent portfolios is individually significant to our licensing and enforcement business as a whole.

We have strategically chosen to shift the focus of our operating business to increasingly serve a smaller number of customers each having higher quality patent portfolios. High quality patent portfolios are typically associated with higher numbers of varied defensible claims, higher revenue potential, originating from high-pedigreed patent owners and/or possessing a relatively large number of prospective licensees. In this regard, commencing in the later portion of 2013 and early 2014, we have continued the shift in our focus at our point of patent intake, from quantity to quality.

We continue to identify and explore opportunities for partnering with companies in the technology and other sectors for the licensing and enforcement of their high quality patented technologies, and are also expanding our activity in international markets, both of which we expect will expand and diversify our future revenue generating opportunities.

Overview - Three months ended June 30, 2015 compared with the three months ended June 30, 2014

• Revenues decreased $9.7 million, or 19%, to $40.3 million, as compared to $50.1 million in the comparable prior year quarter, due primarily to a decrease in the average revenue per agreement, partially offset by an increase in the number of agreements executed.

• Income before income taxes was $896,000 for the three months ended June 30, 2015, as compared to a loss before income taxes of $8.4 million for the three months ended June 30, 2014. The change was due primarily to a 62% decrease in inventor royalties and contingent legal fees and a 20% decrease in other operating expenses as described below, which was partially offset by the 19% decrease in revenues described above.

• Cost of Revenues and Other Operating Expenses:

• Inventor royalties and contingent legal fees, on a combined basis, decreased $11.0 million, or 62%, compared to the 19% decrease in related revenues for the same periods, due primarily to a greater percentage of revenues generated in the second quarter of 2015 having lower inventor royalty obligations, due to an increase in upfront advance recovery related preferred returns, as compared to the portfolios generating revenues in the prior year quarter.

• Litigation and licensing expenses-patents decreased $1.8 million, or 17%, to $9.0 million, due primarily to a decrease in patent prosecution, litigation support and third-party technical consulting expenses associated with ongoing and new licensing and enforcement programs commenced since the end of the comparable prior year quarter.

• Amortization of patents decreased $2.3 million, or 15%, to $13.2 million, due primarily to a decrease in accelerated amortization related to patent portfolio dispositions totaling $2.7 million and a decrease in scheduled amortization of $343,000. The decrease was partially offset by a $1.0 million increase in scheduled amortization for patent investments made since the end of the prior year period.

• Marketing, general and administrative expenses decreased $3.6 million, or 27%, to $9.6 million, due primarily to a net decrease in non-cash stock compensation charges, a decrease in variable performance-based compensation costs and a decrease in other corporate, general and administrative costs.

• The effective tax rates for the three months ended June 30, 2015 and 2014 were 13% and 56%, respectively. Tax expense for the periods presented primarily reflects the impact of foreign withholding taxes related to revenue

agreements executed with third party licensees domiciled in foreign jurisdictions, and valuation allowances recorded for foreign withholding tax credits and net operating loss related tax assets generated during the periods.

Overview - Six months ended June 30, 2015 compared with the six months ended June 30, 2014

• Revenues increased $11.9 million, or 19%, to $74.5 million, as compared to $62.7 million in the comparable prior year period, due primarily to an increase in the total number of agreements executed.

• Loss before income taxes decreased 64%, to $12.5 million, as compared to $34.4 millionin the comparable prior year period, due primarily to a 19% increase in revenues, a 12% decrease in patent amortization expense, a 19% decrease in marketing, general and administrative expenses, and an 11% decrease in litigation and licensing expenses - patents.

• Cost of Revenues and Other Operating Expenses:

• Inventor royalties and contingent legal fees, on a combined basis, increased $637,000, or 3%, as compared to the 19% increase in related revenues for the same periods, due primarily to a greater percentage of revenues generated during the six months ended June 30, 2015 having lower inventor royalty obligations, due to an increase in upfront advance recovery related preferred returns, as compared to the portfolios generating revenues during the six months ended June 30, 2014.

• Litigation and licensing expenses-patents decreased $2.1 million, or 11%, to $17.7 million, due primarily to a decrease in patent prosecution and third-party technical consulting expenses associated with ongoing and new licensing and enforcement programs commenced since the end of the comparable prior year quarter.

• Amortization of patents decreased $3.7 million, or 12%, to $26.3 million, due primarily to a decrease in patent impairment charges totaling $2.6 million and a decrease in accelerated amortization related to patent portfolio dispositions totaling $2.7 million, which was partially offset by an increase in scheduled amortization expense for patent portfolio investments made since the end of the prior year period totaling $1.9 million.

• Marketing, general and administrative expenses decreased $4.7 million, or 19%, to $20.2 million, due primarily to a net decrease in non-cash stock compensation charges, a decrease in variable performance-based compensation costs and a decrease in other corporate, general and administrative costs.

• The effective tax rates for the six months ended June 30, 2015 and 2014 were 2% and 10%, respectively. Tax expense for the periods presented primarily reflects the impact of foreign withholding taxes related to revenue agreements executed with third party licensees domiciled in foreign jurisdictions, and valuation allowances recorded for foreign withholding tax credits and net operating loss related tax assets generated during the periods.

Investments in Patent Portfolios

We also measure and assess the performance and growth of the patent licensing and enforcement businesses conducted by our operating subsidiaries based on patent portfolio partnering / intake opportunities identified and/or closed by our operating subsidiaries on an annual basis. During the six months ended June 30, 2015, we made additional investments in existing patent portfolios added in prior periods, with no new portfolios added during the six month 2015 period. In July 2015, we added two additional patent portfolios, one of the portfolios pertaining to technology in the energy vertical and the other portfolio relating to the improved operation of e-commerce server farms.

Refer to “Liquidity and Capital Resources” below for information regarding the impact on the consolidated financial statements of upfront advances and milestone payments made in connection with patent partnering and investment activities during the periods presented.

Consistent with our strategic shift towards working with a smaller number of high quality portfolios, we continue to identify numerous opportunities in our patent portfolio intake pipeline to assess and analyze potential opportunities to invest in high quality patent portfolios in the technology, automotive and energy verticals. Future patent portfolio intake arrangements will continue to expand and diversify our future revenue generating opportunities. Our operating subsidiaries are principals in the licensing and enforcement effort, obtaining control of the rights in the patent portfolio, or control of the patent portfolio outright.

Patent Licensing and Enforcement

We expect patent-related legal expenses to continue to fluctuate from period to period based on the factors summarized herein, in connection with future trial dates, international enforcement, strategic patent portfolio prosecution and our current and future patent portfolio investment, prosecution, licensing and enforcement activities. The pursuit of enforcement actions in connection with our licensing and enforcement programs can involve certain risks and uncertainties, including the following:

• Increases in patent-related legal expenses associated with patent infringement litigation, including, but not limited to, increases in costs billed by outside legal counsel for discovery, depositions, economic analyses, damages assessments, expert witnesses and other consultants, re-exam and inter partes review costs, case-related audio/video presentations and other litigation support and administrative costs could increase our operating costs and decrease our profit generating opportunities;

• Our patented technologies and enforcement actions are complex and, as a result, we may be required to appeal adverse decisions by trial courts in order to successfully enforce our patents. Moreover, such appeals may not be successful;

• New legislation, regulations or rules related to enforcement actions, including any fee or cost shifting provisions, could significantly increase our operating costs and decrease our profit generating opportunities. Increased focus on the growing number of patent-related lawsuits may result in legislative changes which increase our costs and related risks of asserting patent enforcement actions. For instance, the United States House of Representatives passed a bill that would require non-practicing entities that bring patent infringement lawsuits to pay legal costs of the defendants, if the lawsuits are unsuccessful and certain standards are not met;

• Courts may rule that our subsidiaries have violated certain statutory, regulatory, federal, local or governing rules or standards by pursuing such enforcement actions, which may expose us and our operating subsidiaries to material liabilities, which could harm our operating results and our financial position; and

• The complexity of negotiations and potential magnitude of exposure for potential infringers associated with higher quality patent portfolios may lead to increased intervals of time between the filing of litigation and potential revenue events (i.e. markman dates, trial dates), which may lead to increased legal expenses, consistent with the higher revenue potential of such portfolios.

Critical Accounting Estimates

Our unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. Preparation of these consolidated statements requires management to make judgments and estimates. Some accounting policies have a significant impact on amounts reported in these consolidated financial statements. A summary of significant accounting policies and a description of accounting policies that are considered critical may be found in the audited consolidated financial statements and notes thereto and under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” included in our Annual Report on Form 10-K for the year ended December 31, 2014. Refer to Note 2 to the consolidated financial statements included in this report.

Goodwill Impairment Testing

Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Factors we consider important, which could trigger an impairment review, include the following:

• significant decline in our stock price for a sustained period;

• significant underperformance relative to expected historical or projected future operating results;

• significant changes in the manner of use of assets or the strategy for our overall business;

• significant negative industry or economic trends; and

• significant adverse changes in legal factors or in the business climate, including adverse regulatory actions or assessments.

20

We consider our market capitalization and other valuation techniques as applicable, and the carrying value of our assets and liabilities, including goodwill, when performing goodwill impairment tests. When conducting our annual and interim goodwill impairment assessments, we initially perform a qualitative evaluation of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, we then apply a two-step impairment test. The two-step impairment test first compares the fair value of our reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and we are not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, we are required to determine the implied fair value of the reporting unit’s goodwill and if the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations.

We assessed the impact of the recent downward volatility in our stock price and concluded that the decline constitutes a triggering event requiring an interim goodwill impairment test pursuant to ASC Topic 350, "Intangibles-Goodwill and Other." We conducted the first step of the goodwill impairment test for our single reporting unit as of June 30, 2015. The fair value of the reporting unit exceeded its carrying value as of June 30, 2015, and therefore, goodwill was determined to not be impaired as of June 30, 2015.

Fair value was estimated using the “Income Approach,” as described by ASC 820, “Fair Value Measurements and Disclosures,” focusing on the estimated future income-producing capability of our company's assets, principally our patent portfolios. The underlying premise of this approach is that the value of the company can be measured by the present value of the estimated future net economic benefit (cash receipts less cash outlays). The approach contemplates estimates of after-tax cash flows attributable to the company's aggregate assets and converting these after-tax cash flows to present value through “discounting.” The discounting process contemplates an estimated rate of return that accounts for both the time value of money and investment risk factors. The cash inflows considered were comprised of an estimate of revenues to be generated from future licensing. Estimated cash outflows were based on estimated contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to estimated revenues, in addition to other estimates of out-of-pocket expenses associated with licensing and enforcement and ongoing operations. Net cash flows also considered utilization of our applicable tax assets, including net operating loss carryforwards, subject to applicable limitations on use.

As described above, in assessing the recoverability of goodwill, significant judgment is required in connection with estimates of fair values, estimates of the amount and timing of future cash inflows and outflows, time and risk related discount factors and estimates of other factors that are used to determine the fair value of the company. These estimates and judgments may change in future periods based on new facts and circumstances. For example, significant declines in our estimates of revenues due to future adverse litigation or trial outcomes, adverse rulings by the courts or other regulatory bodies that increase the complexity of patent law and the litigation process, or increases in costs associated with our current or future licensing and enforcement programs, could have a material impact on our estimates of fair value in connection with future interim or annual impairment tests. If these estimates or related projections result in material reductions to our estimates of fair value in future periods, future intangible asset and/or goodwill impairment tests may result in material impairment charges to earnings. At June 30, 2015, the goodwill balance totaled $30.1 million.

Litigation and Licensing Expenses - Patents.  Litigation and licensing expenses-patents include patent-related prosecution and enforcement costs incurred by outside patent attorneys engaged on an hourly basis and the out-of-pocket expenses incurred by law firms engaged on a contingent fee basis.  Litigation and licensing expenses-patents also includes licensing and enforcement related third-party patent research, development, consulting, and other costs incurred in connection with the licensing and enforcement of patent portfolios. 

Litigation and licensing expenses-patents decreased due to a net decrease in patent prosecution, litigation support and third-party technical consulting expenses associated with ongoing and new licensing and enforcement programs commenced since the end of the comparable prior year quarter. We expect patent-related legal expenses to continue to fluctuate period to period as we incur increased costs related to upcoming scheduled and/or anticipated trial dates, international enforcement activities and strategic patent portfolio prosecution activities over the next several fiscal quarters, as we continue to focus on our investments in these areas.

Provision for Income Taxes. Tax expense for the three and six months ended June 30, 2015 and 2014 reflects the impact of foreign withholding taxes related to certain revenue agreements executed with third party licensees domiciled in foreign jurisdictions, and valuation allowances recorded for foreign withholding tax credits and net operating loss related tax assets generated during the periods.

Liquidity and Capital Resources

General

Our primary sources of liquidity are cash, cash equivalents and investments on hand generated from our operating activities and proceeds from previous equity financings.

Our management believes that our cash and cash equivalent balances, investments and anticipated cash flows from operations will be sufficient to meet our cash requirements through at least August 2016 and for the foreseeable future. We may, however, encounter unforeseen difficulties that may deplete our capital resources more rapidly than anticipated, including those set forth under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014.  Any efforts to seek additional funding could be made through issuances of equity or debt, or other external financing.  However, additional funding may not be available on favorable terms, or at all. The capital and credit markets have experienced extreme volatility and disruption since late 2007, and the volatility and impact of the disruption has continued into 2015.  At times during this period, the volatility and disruption has reached unprecedented levels. In several cases, the markets have exerted downward pressure on stock prices and credit capacity for certain issuers, and the commercial paper markets may not be a reliable source of short-term financing for us. If we fail to obtain additional financing when needed, we may not be able to execute our business plans and our business, conducted by our operating subsidiaries, may suffer.

Certain of Acacia’s operating subsidiaries are often required to engage in litigation to enforce their patents and patent rights.  In connection with any of our operating subsidiaries’ patent enforcement actions, it is possible that a defendant may request and/or a court may rule that an operating subsidiary has violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions.  In such event, a court may issue monetary sanctions against us or our operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material.

Cash, Cash Equivalents and Investments

Our consolidated cash and cash equivalents and investments on hand, excluding restricted cash balances, totaled $156.2 million at June 30, 2015, compared to $193.0 million at December 31, 2014.  The net change in cash and cash equivalents for the periods presented was comprised of the following (in thousands):

Investing activities	2,874			33,189
Financing activities	(11,811		)	(13,195		)

Cash Flows from Operating Activities.  Cash receipts from licensees for the six months ended June 30, 2015increased35%, to $57.2 million, as compared to $42.2 million in the comparable 2014 period, primarily reflecting the net increase in revenues for the same periods, as discussed above. Cash outflows from operations (excluding restricted cash) for the six months ended June 30, 2015increased23%, to $52.9 million, as compared to $42.8 million in the comparable 2014 period, primarily due to the net impact of the timing of cash receipts from licensees and related payments of inventor royalties and contingent legal fees, and the timing of payments to other third-parties in the ordinary course, for the same periods. Refer to “Working Capital” below for additional information.

Restricted Cash. In March 2015, an operating subsidiary of ours entered into a Guarantee with a bank in the amount of $10.7 million, in connection with enforcing a ruling in a German patent court granting an injunction against the defendants in the related patent infringement case. The Guarantee is secured by a cash deposit at the contracting bank totaling $10.7 million, which is classified as restricted cash in the June 30, 2015 balance sheet. See below for additional information.

In April 2013, our Board of Directors approved the adoption of a cash dividend policy that calls for the payment of an expected total annual cash dividend of $0.50 per common share, payable in the amount of $0.125 per share per quarter. Under the policy, we paid cash dividends totaling $12.7 million and $12.5 million during the six months ended June 30, 2015 and 2014, respectively.

Working Capital

Working capital (including restricted cash) at June 30, 2015 increased to $179.0 million, compared to $172.8 million at December 31, 2014. Consolidated accounts receivable from licensees increased to $37.6 million at June 30, 2015, compared to $20.2 million at December 31, 2014. Consolidated royalties and contingent legal fees payable increased to $20.2 million at June 30, 2015, compared to $14.4 million at December 31, 2014.  

26

The majority of accounts receivable from licensees at June 30, 2015 were collected or scheduled to be collected in the third quarter of 2015, in accordance with the terms of the related underlying agreements.  The majority of royalties and contingent legal fees payable are scheduled to be paid in the third or fourth quarter of 2015, subsequent to receipt by us of the related fee payments from licensees, in accordance with the underlying contractual arrangements.

Off-Balance Sheet Arrangements

Except as set forth below, we have not entered into off-balance sheet financing arrangements, other than operating leases.  We have no significant commitments for capital expenditures in 2015.  We have no long-term debt. The following table lists our known contractual obligations and future cash commitments as of June 30, 2015 (in thousands):

	Payments Due by Period (In thousands)
Contractual Obligations	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Operating leases	$	7,298	$	699	$	3,151	$	3,281	$	167

Standby Letter of Credit and Guarantee Arrangement. In March 2015, an operating subsidiary of ours entered into a standby letter of credit and guarantee arrangement (“Guarantee”) with a bank in the amount of $10.7 million, for purposes of enforcing a court ruling in a German patent court granting an injunction against the defendants in the related patent infringement case. An injunction is an equitable remedy in the form of a court order that compels the defendant(s) to cease marketing, offering for sale or importing applicable infringing products into applicable jurisdiction(s).

Under German law, in order to enforce the injunction granted by the court, a Guarantee is required to be furnished by our operating subsidiary, the plaintiff in the case, for potential payment to the defendants of any applicable claims which may be incurred by the defendants as a result of the enforcement of the injunction, only in the event that the aforementioned court ruling is subsequently successfully appealed by the defendants or otherwise amended. The Guarantee is required to be issued unlimited with respect to time, until appropriately extinguished in accordance with German law. The Guarantee will be extinguished when a relevant extinguishment order by the court having jurisdiction takes effect, typically occurring when the related infringement case has been settled or a final non-appealable decision has been issued by the court.

The Guarantee is secured by a cash deposit at the contracting bank totaling $10.7 million, which is classified as restricted cash in the June 30, 2015 balance sheet. The Guarantee expires on April 10, 2016, however, it is automatically extended without amendment for a period of one (1) year from the present or any future expiration date, unless at least 30 days prior to any expiration date, the Guarantee is extinguished in accordance with German law. The Guarantee facility fee is 1.15% per year, and the related expense is included in the statement of operations.

Uncertain Tax Positions.  At June 30, 2015, we had total unrecognized tax benefits of approximately $2.1 million, including a recorded noncurrent liability of $85,000 related to unrecognized tax benefits primarily associated with state taxes. No interest and penalties have been recorded for the unrecognized tax benefits as of June 30, 2015. If recognized, approximately $2.1 million would impact our effective tax rate. We do not expect that the liability for unrecognized tax benefits will change significantly within the next 12 months. There was no activity related to the gross unrecognized tax benefits for the periods presented.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal while concurrently maximizing the income we receive from our investments without significantly increasing risk. Some of the securities that we invest in may be subject to interest rate risk and/or market risk. This means that a change in prevailing interest rates, with respect to interest rate risk, or a change in the value of the United States equity markets, with respect to market risk, may cause the principal amount or market value of the investments to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the

27

then-prevailing rate and the prevailing interest rate later rises, the current value of the principal amount of our investment may decline. To minimize these risks in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, high-grade corporate bonds, government and non-government debt securities and certificates of deposit.

At June 30, 2015, our short-term investments were comprised of AAA-rated money market funds that invest in first-tier only securities, which primarily include domestic commercial paper, securities issued or guaranteed by the U.S. government or its agencies, U.S. bank obligations, and fully collateralized repurchase agreements (included in cash and cash equivalents in the accompanying consolidated balance sheets) and direct investments in highly liquid, AAA-rated, U.S. government securities.

In general, money market funds are not subject to market risk because the interest paid on such funds fluctuates with the prevailing interest rate. Accordingly, a 100 basis point increase in interest rates or a 10% decline in the value of the United States equity markets would not be expected to have a material impact on the value of such money market funds. Investments in U.S. government fixed income securities are subject to interest rate risk and will decline in value if interest rates increase. However, due to the relatively short duration of our investment portfolio, an immediate 10% change in interest rates would have no material impact on our financial condition, results of operations or cash flows. Declines in interest rates over time will, however, reduce our interest income.

Item 4.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures.

Our management, with the participation and under the supervision of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act) as of the end of the period covered by this quarterly report. Based on that evaluation, our chief executive officer and our chief financial officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

Changes in Internal Control Over Financial Reporting.

There were no changes in our internal control over financial reporting that occurred during our last fiscal quarter (the quarter ended June 30, 2015) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls.

Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Description of Business and Basis of Presentation

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business. As used herein, “Acacia” and the “Company” refer to Acacia Research Corporation and/or its wholly and majority-owned and controlled operating subsidiaries, and/or where applicable, its management.  All patent investment, prosecution, licensing and enforcement activities are conducted solely by certain of Acacia’s wholly and majority-owned and controlled operating subsidiaries.

Acacia’s operating subsidiaries invest in, license and enforce patented technologies. Acacia’s operating subsidiaries partner with inventors and patent owners, applying their legal and technology expertise to patent assets to unlock the financial value in their patented inventions. Acacia is an intermediary in the patent marketplace, bridging the gap between invention and application, facilitating efficiency and delivering monetary rewards to patent owners.

Acacia’s operating subsidiaries generate revenues and related cash flows from the granting of intellectual property rights for the use of patented technologies that its operating subsidiaries control or own. Acacia’s operating subsidiaries assist patent owners with the prosecution and development of their patent portfolios, the protection of their patented inventions from unauthorized use, the generation of licensing revenue from users of their patented technologies and, where necessary, with the enforcement against unauthorized users of their patented technologies through the filing of patent infringement litigation.

Acacia’s operating subsidiaries are principals in the licensing and enforcement effort, obtaining control of the rights in the patent portfolio, or control of the patent portfolio outright. Acacia’s operating subsidiaries own or control the rights to multiple patent portfolios, which include U.S. patents and certain foreign counterparts, covering technologies used in a wide variety of industries.

Basis of Presentation.  The accompanying consolidated financial statements include the accounts of Acacia and its wholly and majority-owned and controlled subsidiaries. Material intercompany transactions and balances have been eliminated in consolidation. Noncontrolling interests in Acacia’s majority-owned and controlled operating subsidiaries (“noncontrolling interests”) are separately presented as a component of stockholders’ equity in the consolidated statements of financial position for the applicable periods presented. Consolidated net income (loss) is adjusted to include the net (income) loss attributed to noncontrolling interests in the consolidated statements of operations. Refer to the accompanying consolidated financial statements for total noncontrolling interests, net (income) loss attributable to noncontrolling interests and contributions from and distributions to noncontrolling interests, for the applicable periods presented.

A wholly owned subsidiary of Acacia is the general partner of the Acacia Intellectual Property Fund, L.P. (the “Acacia IP Fund”), which was formed in August 2010. The Acacia IP Fund is included in the Company’s consolidated financial statements for the periods presented because Acacia’s wholly owned subsidiary, which is the majority owner and general partner, has the ability to control the operations and activities of the Acacia IP Fund.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, certain information and footnotes required by accounting principles generally accepted in the United States of America in annual financial statements have been omitted or condensed in accordance with quarterly reporting requirements of the Securities and Exchange Commission (“SEC”).  These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2014, as reported by Acacia in its Annual Report on Form 10-K filed with the SEC.  The year end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America.

The condensed consolidated interim financial statements of Acacia include all adjustments of a normal recurring nature which, in the opinion of management, are necessary for a fair statement of Acacia’s consolidated financial position as of June 30, 2015, and results of its operations and its cash flows for the interim periods presented.  The consolidated results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the entire fiscal year.

Goodwill [Abstract]

Goodwill Disclosure [Text Block]

GOODWILL

Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Factors considered important, which could trigger an impairment review, include the following:

• significant underperformance relative to expected historical or projected future operating results;

• significant changes in the manner of use of the assets or the strategy for Acacia's overall business; 

• significant negative industry or economic trends; 

• significant adverse changes in legal factors or in the business climate, including adverse regulatory actions or assessments; and 

• significant decline in the Company's stock price for a sustained period.

The Company considers its market capitalization and other valuation techniques as applicable, and the carrying value of its assets and liabilities, including goodwill, when performing goodwill impairment tests. When conducting annual and interim goodwill impairment assessments, the Company initially performs a qualitative evaluation (considering factors described above as applicable) of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, the Company then applies a two-step impairment test. The two-step impairment test first compares the fair value of Acacia's reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, then the Company is required to determine the implied fair value of the reporting unit’s goodwill and if the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations.

As of June 30, 2015, the Company assessed the impact of the recent downward volatility in the Company's stock price and concluded that the decline constituted a triggering event requiring an interim goodwill impairment test pursuant to ASC Topic 350, "Intangibles-Goodwill and Other." The Company conducted the first step of the goodwill impairment test described above for its single reporting unit as of June 30, 2015. The fair value of the reporting unit exceeded its carrying value as of June 30, 2015, and therefore goodwill was determined to not be impaired as of June 30, 2015.

Fair value was estimated using the “Income Approach,” as described by ASC 820, “Fair Value Measurements and Disclosures,” focusing on the estimated future income-producing capability of the Company's assets, principally its patent portfolios, to determine the present value of the estimated future net economic benefit (cash receipts less cash outlays). The approach included estimates of after-tax cash flows attributable to the Company's aggregate assets and converting these after-tax cash flows to present value through “discounting.” The discounting process contemplated an estimated rate of return that accounts for both the time value of money and investment risk factors. The cash inflows considered were comprised of an estimate of revenues from future licensing. Estimated cash outflows were based on estimated contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to estimated revenues, in addition to other estimates of out-of-pocket expenses associated with licensing and enforcement and ongoing operations. Net cash flows also considered utilization of the Company's applicable tax assets, including net operating loss carryforwards, subject to applicable limitations on use.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Accounting Policies [Abstract]

Revenue Recognition

Revenue Recognition.  Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been substantially performed pursuant to the terms of the arrangement, (iii) amounts are fixed or determinable, and (iv) the collectibility of amounts is reasonably assured.

In general, revenue arrangements provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by Acacia’s operating subsidiaries.  These rights typically include some combination of the following:  (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by Acacia’s operating subsidiaries, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and (iv) the dismissal of any pending litigation.  The intellectual property rights granted may be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment.  Pursuant to the terms of these agreements, Acacia’s operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on Acacia’s operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverables upon execution of the agreement, or upon receipt of the minimum upfront payment for term agreement renewals.  As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, when collectibility is reasonably assured, or upon receipt of the minimum upfront fee for term agreement renewals, and when all other revenue recognition criteria have been met.

For the periods presented herein, the majority of the revenue agreements executed by the Company provided for the payment of one-time, paid-up license fees in consideration for the grant of certain intellectual property rights for patented technology rights owned by our operating subsidiaries. These rights were primarily granted on a perpetual basis, extending until the expiration of the underlying patents.

Cost of Revenues

Cost of Revenues.  Cost of revenues include the costs and expenses incurred in connection with Acacia’s patent licensing and enforcement activities, including inventor royalties paid to original patent owners, contingent legal fees paid to external patent counsel, other patent-related legal expenses paid to external patent counsel, licensing and enforcement related research, consulting and other expenses paid to third-parties and the amortization of patent-related investment costs.  These costs are included under the caption “Cost of revenues” in the accompanying consolidated statements of operations.

Inventor Royalties and Contingent Legal Expenses

Inventor Royalties and Contingent Legal Expenses. Inventor royalties are expensed in the consolidated statements of operations in the period that the related revenues are recognized.  In certain instances, pursuant to the terms of the underlying inventor agreements, upfront advances paid to patent owners by Acacia’s operating subsidiaries are recoverable from future net revenues.  Patent costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statements of operations.  Any unamortized upfront advances recovered from net revenues are expensed in the period recovered, and included in amortization expense in the consolidated statements of operations.

Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, Acacia’s operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.  

Use of Estimates

Use of Estimates.  The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, stock-based compensation expense, impairment of marketable securities and intangible assets including goodwill, the determination of the economic useful life of amortizable intangible assets, income taxes and valuation allowances against net deferred tax assets and the application of the acquisition method of accounting for business combinations, require its most difficult, subjective or complex judgments.

Concentrations

Concentrations. One licensee individually accounted for 74% of revenues recognized during the three months ended June 30, 2015, and two licensees accounted for 40% and 27% of revenues recognized during the six months ended June 30, 2015. Two licensees individually accounted for 58% and 14% of revenues recognized during the three months ended June 30, 2014, and two licensees accounted for 46% and 11% of revenues recognized during the six months ended June 30, 2014.

One licensee individually represented approximately 80% of accounts receivable at June 30, 2015. The majority of accounts receivable balances at June 30, 2015 were collected in July 2015. Three licensees individually represented approximately 30%, 17% and 15% of accounts receivable at December 31, 2014. For the three and six months ended June 30, 2015, 18% and 38%, respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions, based on the jurisdiction of the entity obligated to satisfy payment obligations pursuant to the applicable revenue arrangement. For the three and six months ended June 30, 2014, 79% and 67%, respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions. The Company does not have any material foreign operations.

Stock-Based Compensation

Stock-Based Compensation. The compensation cost for stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (the vesting period of the equity award) which is two to four years. The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units granted and the grant date market price of the underlying common stock. Stock-based compensation expense is recorded only for those awards expected to vest using an estimated forfeiture rate.

Fair Value Measurements

Fair Value Measurements. U.S. GAAP defines fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established to measure fair value is defined as follows:

● Level 1 - Observable Inputs:  Quoted prices in active markets for identical investments;

● Level 2 - Pricing Models with Significant Observable Inputs:  Other significant observable inputs, including quoted prices for similar investments, interest rates, credit risk, etc.; and

● Level 3 - Unobservable Inputs:  Significant unobservable inputs, including the entity’s own assumptions in determining the fair value of investments.

 Whenever possible, the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value.

Investments in and Impairment of Marketable Securities

Investments in Marketable Securities. Investments in securities with original maturities of greater than three months and less than one year and other investments representing amounts that are available for current operations are classified as short-term investments, unless there are indications that such investments may not be readily sold in the short term. The fair values of these investments approximate their carrying values. For the periods presented, all of Acacia’s short term investments were classified as available-for-sale, which are reported at fair value on a recurring basis using observable inputs (Level 1), with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders’ equity until realized. Realized and unrealized gains and losses are recorded based on the specific identification method. Interest on all securities is included in interest income.

Short-term marketable securities for the periods presented were comprised of the following (in thousands):

	June 30, 2015
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities	$	37,270	$	10	$	(190	)	$	37,090
Total short-term investments	$	37,270	$	10	$	(190	)	$	37,090

	December 31, 2014
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities	$	58,819	$	2	$	(263	)	$	58,558
Total short-term investments	$	58,819	$	2	$	(263	)	$	58,558

The gross unrealized loss can be primarily attributed to a combination of market conditions as well as the demand for and duration of the U.S. government fixed income securities. The Company has the ability to hold these securities until maturity, currently has no intent to sell, there is no requirement to sell and the Company believes that it can recover the amortized cost of these investments. The Company has found no evidence of impairment due to credit losses in its portfolio. Therefore, these unrealized losses were recorded in other comprehensive income (loss). However, the Company cannot provide any assurance that its portfolio of short-term marketable securities will not be impacted by adverse conditions in the financial markets, which may require the Company in the future to record an impairment charge for credit losses which could adversely impact its financial results.

Patents

Patents.  Patents include the cost of patents or patent rights (hereinafter, collectively “patents”) obtained from third-parties or obtained in connection with business combinations. Capitalized patent costs are amortized utilizing the straight-line method over their remaining economic useful lives, ranging from one to nine years. Certain patent application and prosecution costs incurred to secure additional patent claims, that based on management’s estimates are deemed to be recoverable, are capitalized and amortized over the remaining estimated economic useful life of the related patent portfolio.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]

Goodwill. Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (December 31) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Acacia considers its market capitalization and other valuation techniques and the carrying value of its assets and liabilities, including goodwill, when performing its goodwill impairment test. When conducting its annual goodwill impairment assessment, the Company initially performs a qualitative evaluation of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, the Company then applies a two-step impairment test. The two-step impairment test first compares the fair value of the Company’s reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, the Company determines the implied fair value of the reporting unit’s goodwill and if the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations. Refer to Note 9 for additional information.

Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]

Impairment of Long-lived Assets. Acacia reviews long-lived assets and intangible assets for potential impairment annually (quarterly for patents) and when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss is recorded equal to the excess of the asset’s carrying value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available or not indicative of current fair value, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows.

Fair value is generally estimated using the “Income Approach,” focusing on the estimated future net income-producing capability of the patent portfolios over the estimated remaining economic useful life. Estimates of future after-tax cash flows are converted to present value through “discounting,” including an estimated rate of return that accounts for both the time value of money and investment risk factors. Estimated cash inflows are typically based on estimates of reasonable royalty rates for the applicable technology, applied to estimated market data. Estimated cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio’s licensing and enforcement program. The analysis also contemplates consideration of current information about the patent portfolio including, status and stage of litigation, periodic results of the litigation process, technology coverage and other pertinent information that could impact future net cash flows.

Income Taxes

Income Taxes.  Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in Acacia’s consolidated financial statements or consolidated income tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized, or if it is determined that there is uncertainty regarding future realizability of such assets.

The provision for income taxes for interim periods is determined using an estimate of Acacia’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, Acacia updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, a cumulative adjustment is recorded.  

The Company's effective tax rates were 13% and 2% for the three and six months ended June 30, 2015, respectively, and 56% and 10% for the three and six months ended June 30, 2014. The effective rates for the periods presented primarily reflect the impact of foreign withholding taxes related to certain revenue agreements executed with third party licensees domiciled in foreign jurisdictions, and valuation allowances recorded for foreign withholding tax credits and net operating loss related tax assets generated during the periods.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Identifiable Intangible Assets

PATENTS

Acacia’s only identifiable intangible assets at June 30, 2015 and December 31, 2014 are patents and patent rights.  Patent-related accumulated amortization totaled $192,831,000 and $166,565,000 as of June 30, 2015 and December 31, 2014, respectively.

Acacia’s patents have remaining estimated economic useful lives ranging from one to nine years.  The weighted-average remaining estimated economic useful life of Acacia’s patents is approximately six years.  The following table presents the scheduled annual aggregate amortization expense as of June 30, 2015 (in thousands):

For the years ending December 31,
Remainder of 2015	$	26,080
2016	49,765
2017	48,676
2018	44,549
2019	38,917
Thereafter	54,350
	$	262,337

For the six months ended June 30, 2015 and 2014, Acacia paid patent related investment costs, including up-front patent portfolio advances and previously accrued milestone payments related to patent related investments made in prior periods, totaling $18,667,000 and $22,096,000, respectively.  The underlying patents have estimated economic useful lives of approximately four to ten years. Included in net additions to capitalized patent costs during the six months ended June 30, 2014 are accrued patent investment costs totaling $3,000,000 which are amortized over the estimated economic useful life of the related patents.

During the six months ended June 30, 2014, certain Acacia operating subsidiaries elected to sell their rights to patent portfolios, resulting in the acceleration of amortization expense for the patent-related assets totaling $2,702,000. Proceeds from the sale of patents and the related gain on sale for the six months ended June 30, 2014 were $3,500,000 and $833,000, respectively. Included in amortization of patents for the six months ended June 30, 2014 was accelerated amortization related to the partial write-down of a patent portfolio, due to a reduction in expected estimated future net cash flows, totaling $2,565,000.

Earnings Per Share [Abstract]

Earnings Per Share

INCOME (LOSS) PER SHARE

The Company computes net income (loss) attributable to common stockholders using the two-class method required for capital structures that include participating securities. Under the two-class method, securities that participate in non-forfeitable dividends, such as the Company’s outstanding unvested restricted stock, are considered “participating securities.”

In applying the two-class method, (i) basic net income (loss) per share is computed by dividing net income (loss) (less any dividends paid on participating securities) by the weighted average number of shares of common stock and participating securities outstanding for the period and (ii) diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying the two-class method and the treasury stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options, and restricted stock units for calculations utilizing the two-class method, and also include unvested restricted stock, when utilizing the treasury method.

The following table presents the weighted-average number of common shares outstanding used in the calculation of basic and diluted income (loss) per share:

COMMITMENTS AND CONTINGENCIES

Bank Guarantee

In March 2015, an operating subsidiary of Acacia entered into a standby letter of credit and guarantee arrangement (“Guarantee”) with a bank in the amount of $10,718,000, for purposes of enforcing a court ruling in a German patent court granting an injunction against the defendants in the related patent infringement case. An injunction is an equitable remedy in the form of a court order that compels the defendant(s) to cease marketing, offering for sale or importing applicable infringing products into applicable jurisdiction(s).

Under German law, in order to enforce the injunction granted by the court, a Guarantee is required to be furnished by our operating subsidiary, the plaintiff in the case, for potential payment to the defendants of any applicable claims which may be incurred by the defendants as a result of the enforcement of the injunction, only in the event that the aforementioned court ruling is subsequently successfully appealed by the defendants or otherwise amended. The Guarantee is required to be issued unlimited with respect to time, until appropriately extinguished in accordance with German law. The Guarantee will be extinguished when a relevant extinguishment order by the court having jurisdiction takes effect, typically occurring when the related infringement case has been settled or a final non-appealable decision has been issued by the court.

The Guarantee is secured by a cash deposit at the contracting bank totaling $10,718,000, which is classified as restricted cash in the June 30, 2015 balance sheet. The Guarantee expires on April 10, 2016, however, it is automatically extended without amendment for a period of one (1) year from the present or any future expiration date, unless at least 30 days prior to any expiration date, the Guarantee is extinguished in accordance with German law. The Guarantee facility fee is 1.15% per year, and the related expense is included in the consolidated statement of operations.

Patent Enforcement

Certain of Acacia’s operating subsidiaries are often required to engage in litigation to enforce their patents and patent rights.  In connection with any of Acacia’s operating subsidiaries’ patent enforcement actions, it is possible that a defendant may request and/or a court may rule that an operating subsidiary has violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions.  In such event, a court may issue monetary sanctions against Acacia or its operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material.

During the six months ended June 30, 2015, a federal court decided that a lawsuit initiated in 2013 was exceptional. The respective operating subsidiaries have taken steps to challenge the amounts requested including the filing of a notice of appeal. Operating expenses for the six months ended June 30, 2015 included an expense for this matter totaling $426,000.

Other

In February 2011, Michael Strathmann ("Plaintiff") served a Complaint for Violation of the Insurance Fraud Prevention Act (California Insurance Code Section 1871.7) against Acacia, CombiMatrix Corporation, and Dr. Amit Kumar in the Superior Court of the State of California (the "Court") in connection with a prior lawsuit against Nanogen, Inc., that was settled in 2002. Plaintiff alleged that the defendants wrongfully made a claim for insurance coverage for the Nanogen lawsuit leading to a settlement with the insurer. The trial commenced in June 2014. In March 2015, the court issued a final judgment in Acacia's favor, dismissing the complaint with prejudice and affirming its prior rulings in favor of Acacia and the defendants, and against all claims of the Plaintiff.

Acacia is subject to claims, counterclaims and legal actions that arise in the ordinary course of business.  Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on Acacia’s consolidated financial position, results of operations or cash flows.

RECENT ACCOUNTING PRONOUNCEMENTS

Recent Accounting Pronouncements - Not Yet Adopted.

In June 2014, the Financial Accounting Standards Board (the "FASB") issued a new accounting standard which requires that a performance target that affects vesting and could be achieved after the requisite service period shall be treated as a performance condition. Adoption of this standard is required for annual periods beginning after December 15, 2015. Early adoption is permitted. Management is currently evaluating the impact the pronouncement will have on the Company's consolidated financial statements and related disclosures.

In May 2014, the FASB issued a new accounting standards update addressing revenue from contracts with customers, which clarifies existing accounting literature relating to how and when a company recognizes revenue.  Under the standard, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services.  The amendments for this standard update are effective for interim and annual reporting periods beginning after December 15, 2016, and are to be applied retrospectively or the cumulative effect as of the date of adoption, with early application not permitted.  On April 1, 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier if they choose (i.e., the original effective date). Management is currently evaluating the impact the pronouncement will have on the Company's consolidated financial statements and related disclosures.

In August 2014, the FASB issued a new accounting standard which requires management to assess an entity’s ability to continue as a going concern every reporting period including interim periods, and to provide related footnote disclosure in certain circumstances. Adoption of this standard is required for annual periods beginning after December 15, 2016 and are to be applied retrospectively or the cumulative effect as of the date of adoption. Early adoption is permitted. Management is currently evaluating the impact the pronouncement will have on the Company's consolidated financial statements and related disclosures.

In April 2015, the FASB issued an accounting standard update to simplify the presentation of debt issuance costs. The amendments in this accounting standard update require debt issuance costs be presented on the balance sheet as a direct reduction from the carrying amount of the related debt liability. The amendments in this accounting standard update are to be applied retrospectively and are effective for interim and annual reporting periods beginning after December 15, 2015. Management is currently evaluating the impact the pronouncement will have on our consolidated financial statements and related disclosures.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition.  Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) all obligations have been substantially performed pursuant to the terms of the arrangement, (iii) amounts are fixed or determinable, and (iv) the collectibility of amounts is reasonably assured.

In general, revenue arrangements provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by Acacia’s operating subsidiaries.  These rights typically include some combination of the following:  (i) the grant of a non-exclusive, retroactive and future license to manufacture and/or sell products covered by patented technologies owned or controlled by Acacia’s operating subsidiaries, (ii) a covenant-not-to-sue, (iii) the release of the licensee from certain claims, and (iv) the dismissal of any pending litigation.  The intellectual property rights granted may be perpetual in nature, extending until the expiration of the related patents, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment.  Pursuant to the terms of these agreements, Acacia’s operating subsidiaries have no further obligation with respect to the grant of the non-exclusive retroactive and future licenses, covenants-not-to-sue, releases, and other deliverables, including no express or implied obligation on Acacia’s operating subsidiaries’ part to maintain or upgrade the technology, or provide future support or services.  Generally, the agreements provide for the grant of the licenses, covenants-not-to-sue, releases, and other significant deliverables upon execution of the agreement, or upon receipt of the minimum upfront payment for term agreement renewals.  As such, the earnings process is complete and revenue is recognized upon the execution of the agreement, when collectibility is reasonably assured, or upon receipt of the minimum upfront fee for term agreement renewals, and when all other revenue recognition criteria have been met.

For the periods presented herein, the majority of the revenue agreements executed by the Company provided for the payment of one-time, paid-up license fees in consideration for the grant of certain intellectual property rights for patented technology rights owned by our operating subsidiaries. These rights were primarily granted on a perpetual basis, extending until the expiration of the underlying patents.

Cost of Revenues.  Cost of revenues include the costs and expenses incurred in connection with Acacia’s patent licensing and enforcement activities, including inventor royalties paid to original patent owners, contingent legal fees paid to external patent counsel, other patent-related legal expenses paid to external patent counsel, licensing and enforcement related research, consulting and other expenses paid to third-parties and the amortization of patent-related investment costs.  These costs are included under the caption “Cost of revenues” in the accompanying consolidated statements of operations.  

Inventor Royalties and Contingent Legal Expenses. Inventor royalties are expensed in the consolidated statements of operations in the period that the related revenues are recognized.  In certain instances, pursuant to the terms of the underlying inventor agreements, upfront advances paid to patent owners by Acacia’s operating subsidiaries are recoverable from future net revenues.  Patent costs that are recoverable from future net revenues are amortized over the estimated economic useful life of the related patents, or as the prepaid royalties are earned by the inventor, as appropriate, and the related expense is included in amortization expense in the consolidated statements of operations.  Any unamortized upfront advances recovered from net revenues are expensed in the period recovered, and included in amortization expense in the consolidated statements of operations.

Contingent legal fees are expensed in the consolidated statements of operations in the period that the related revenues are recognized. In instances where there are no recoveries from potential infringers, no contingent legal fees are paid; however, Acacia’s operating subsidiaries may be liable for certain out of pocket legal costs incurred pursuant to the underlying legal services agreement.  

Use of Estimates.  The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, stock-based compensation expense, impairment of marketable securities and intangible assets including goodwill, the determination of the economic useful life of amortizable intangible assets, income taxes and valuation allowances against net deferred tax assets and the application of the acquisition method of accounting for business combinations, require its most difficult, subjective or complex judgments.

Concentrations. One licensee individually accounted for 74% of revenues recognized during the three months ended June 30, 2015, and two licensees accounted for 40% and 27% of revenues recognized during the six months ended June 30, 2015. Two licensees individually accounted for 58% and 14% of revenues recognized during the three months ended June 30, 2014, and two licensees accounted for 46% and 11% of revenues recognized during the six months ended June 30, 2014.

One licensee individually represented approximately 80% of accounts receivable at June 30, 2015. The majority of accounts receivable balances at June 30, 2015 were collected in July 2015. Three licensees individually represented approximately 30%, 17% and 15% of accounts receivable at December 31, 2014. For the three and six months ended June 30, 2015, 18% and 38%, respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions, based on the jurisdiction of the entity obligated to satisfy payment obligations pursuant to the applicable revenue arrangement. For the three and six months ended June 30, 2014, 79% and 67%, respectively, of revenues were attributable to licensees domiciled in foreign jurisdictions. The Company does not have any material foreign operations.

Stock-Based Compensation. The compensation cost for stock-based awards is measured at the grant date, based on the fair value of the award, and is recognized as an expense, on a straight-line basis, over the employee’s requisite service period (the vesting period of the equity award) which is two to four years. The fair value of restricted stock and restricted stock unit awards is determined by the product of the number of shares or units granted and the grant date market price of the underlying common stock. Stock-based compensation expense is recorded only for those awards expected to vest using an estimated forfeiture rate.

Fair Value Measurements. U.S. GAAP defines fair value as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available. The three-level hierarchy of valuation techniques established to measure fair value is defined as follows:

● Level 1 - Observable Inputs:  Quoted prices in active markets for identical investments;

● Level 2 - Pricing Models with Significant Observable Inputs:  Other significant observable inputs, including quoted prices for similar investments, interest rates, credit risk, etc.; and

● Level 3 - Unobservable Inputs:  Significant unobservable inputs, including the entity’s own assumptions in determining the fair value of investments.

 Whenever possible, the Company is required to use observable market inputs (Level 1 - quoted market prices) when measuring fair value.

Investments in Marketable Securities. Investments in securities with original maturities of greater than three months and less than one year and other investments representing amounts that are available for current operations are classified as short-term investments, unless there are indications that such investments may not be readily sold in the short term. The fair values of these investments approximate their carrying values. For the periods presented, all of Acacia’s short term investments were classified as available-for-sale, which are reported at fair value on a recurring basis using observable inputs (Level 1), with related unrealized gains and losses in the value of such securities recorded as a separate component of comprehensive income (loss) in stockholders’ equity until realized. Realized and unrealized gains and losses are recorded based on the specific identification method. Interest on all securities is included in interest income.

Short-term marketable securities for the periods presented were comprised of the following (in thousands):

	June 30, 2015
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities	$	37,270	$	10	$	(190	)	$	37,090
Total short-term investments	$	37,270	$	10	$	(190	)	$	37,090

	December 31, 2014
Security Type	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
U.S. government fixed income securities	$	58,819	$	2	$	(263	)	$	58,558
Total short-term investments	$	58,819	$	2	$	(263	)	$	58,558

The gross unrealized loss can be primarily attributed to a combination of market conditions as well as the demand for and duration of the U.S. government fixed income securities. The Company has the ability to hold these securities until maturity, currently has no intent to sell, there is no requirement to sell and the Company believes that it can recover the amortized cost of these investments. The Company has found no evidence of impairment due to credit losses in its portfolio. Therefore, these unrealized losses were recorded in other comprehensive income (loss). However, the Company cannot provide any assurance that its portfolio of short-term marketable securities will not be impacted by adverse conditions in the financial markets, which may require the Company in the future to record an impairment charge for credit losses which could adversely impact its financial results.

Patents.  Patents include the cost of patents or patent rights (hereinafter, collectively “patents”) obtained from third-parties or obtained in connection with business combinations. Capitalized patent costs are amortized utilizing the straight-line method over their remaining economic useful lives, ranging from one to nine years. Certain patent application and prosecution costs incurred to secure additional patent claims, that based on management’s estimates are deemed to be recoverable, are capitalized and amortized over the remaining estimated economic useful life of the related patent portfolio.

Goodwill. Goodwill is tested for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis (December 31) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. Acacia considers its market capitalization and other valuation techniques and the carrying value of its assets and liabilities, including goodwill, when performing its goodwill impairment test. When conducting its annual goodwill impairment assessment, the Company initially performs a qualitative evaluation of whether it is more likely than not that goodwill is impaired. If it is determined by a qualitative evaluation that it is more likely than not that goodwill is impaired, the Company then applies a two-step impairment test. The two-step impairment test first compares the fair value of the Company’s reporting unit to its carrying or book value. If the fair value of the reporting unit exceeds its carrying value, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds its fair value, the Company determines the implied fair value of the reporting unit’s goodwill and if the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then an impairment loss equal to the difference is recorded in the consolidated statement of operations. Refer to Note 9 for additional information.

Impairment of Long-lived Assets. Acacia reviews long-lived assets and intangible assets for potential impairment annually (quarterly for patents) and when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss is recorded equal to the excess of the asset’s carrying value over its fair value. If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available or not indicative of current fair value, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows.

Fair value is generally estimated using the “Income Approach,” focusing on the estimated future net income-producing capability of the patent portfolios over the estimated remaining economic useful life. Estimates of future after-tax cash flows are converted to present value through “discounting,” including an estimated rate of return that accounts for both the time value of money and investment risk factors. Estimated cash inflows are typically based on estimates of reasonable royalty rates for the applicable technology, applied to estimated market data. Estimated cash outflows are based on existing contractual obligations, such as contingent legal fee and inventor royalty obligations, applied to estimated license fee revenues, in addition to other estimates of out-of-pocket expenses associated with a specific patent portfolio’s licensing and enforcement program. The analysis also contemplates consideration of current information about the patent portfolio including, status and stage of litigation, periodic results of the litigation process, technology coverage and other pertinent information that could impact future net cash flows.

Income Taxes.  Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in Acacia’s consolidated financial statements or consolidated income tax returns. A valuation allowance is established to reduce deferred tax assets if all, or some portion, of such assets will more than likely not be realized, or if it is determined that there is uncertainty regarding future realizability of such assets.

The provision for income taxes for interim periods is determined using an estimate of Acacia’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, Acacia updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, a cumulative adjustment is recorded.  

The Company's effective tax rates were 13% and 2% for the three and six months ended June 30, 2015, respectively, and 56% and 10% for the three and six months ended June 30, 2014. The effective rates for the periods presented primarily reflect the impact of foreign withholding taxes related to certain revenue agreements executed with third party licensees domiciled in foreign jurisdictions, and valuation allowances recorded for foreign withholding tax credits and net operating loss related tax assets generated during the periods.
