RPX Corporation

Notes to Consolidated Financial Statements

(Unaudited)

1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying interim consolidated financial statements of RPX Corporation (also referred to herein as “RPX” or the “Company”) are unaudited and have been prepared in accordance with the accounting principles generally accepted in the United States of America (“US GAAP”) and with the instructions for Form 10-Q and Regulation S-X statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s prospectus filed with the Securities and Exchange Commission (“SEC”) on May 4, 2011. The unaudited consolidated financial statements include the accounts of RPX and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The accompanying interim consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the Company’s financial position and results of operations for the periods presented. The consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

There have been no significant new accounting pronouncements or changes to the critical accounting policies disclosed in the Company’s prospectus that have had a significant impact on its consolidated financial statements or notes thereto.

Liquidity and Capital Resources

In May 2011, the Company completed its initial public offering (“IPO”) of its common stock in which the Company issued 9,065,000 common shares and received cash proceeds of $160.2 million, net of underwriting discounts and commissions. The Company incurred offering costs of $2.9 million. Prior to the IPO, substantially all of the Company’s operations and patent asset acquisitions had been financed through the private sale of equity securities, subscription fees collected from its clients and patent-seller financing.

As of June 30, 2011 and December 31, 2010, the Company had cash and cash equivalents of $159.4 million and $46.7 million, respectively, and retained earnings of $25.0 million and $10.7 million, respectively. Management expects that it will use substantial cash in the future to acquire additional patent assets and service the obligations undertaken in connection with prior patent asset purchases. Management believes that the Company has adequate cash resources to continue its operations for the foreseeable future.

Concentration of Risk

The Company is subject to concentrations of credit risk principally attributable to cash and cash equivalents, investments and accounts receivable. The Company places its cash in non-interest bearing accounts at financial institutions which are insured by the Federal Deposit Insurance Corporation. Cash equivalents primarily consist of institutional money market funds and short-term investments consist of U.S. Government and Agency securities.

Credit risk with respect to accounts receivable is generally mitigated by short collection periods and/or subscription agreements that provide for payments in advance of the rendering of services. Two clients accounted for 53% and 37% of accounts receivable at June 30, 2011. Three clients accounted for 45%, 33% and 22% of accounts receivable at December 31, 2010.

No client accounted for 10% or more of subscription fee revenue for the three or six months ended June 30, 2011 and 2010.

Short-Term Investments

The Company holds short-term investments in marketable debt securities, consisting primarily of fixed income U.S. Government and Agency securities. The Company classifies these securities as “available-for-sale”, and carries them at fair value on the consolidated balance sheets. Any unrealized gains or losses are recorded, net of estimated taxes, in accumulated other comprehensive income, a component of stockholders’ equity. Realized gains and losses are recognized upon sale. The specific identification method is used to determine the cost basis of fixed income securities sold.

The Company considers its investments as available to support current operations. Consequently, the Company may not hold securities with maturities greater than twelve months until maturity. As a result, the Company classifies its investments including those with stated maturities beyond twelve months, as current assets in the accompanying consolidated balance sheets.

The Company periodically evaluates its investments for impairment due to declines in market value considered to be “other-than-temporary”. This evaluation consists of several qualitative and quantitative factors, including the Company’s ability and intent to hold the investment until a forecasted recovery occurs, as well as any decline in the investment quality of the security and the severity and duration of the unrealized loss. In the event of a determination that a decline in market value is other-than-temporary, the Company will recognize an impairment loss, and a new cost basis in the investment will be established. To date, the Company has not recorded any impairment related to its investments in its consolidated statement of operations.

Restricted Cash

The Company had restricted cash of $720,000 at both June 30, 2011 and December 31, 2010 pledged under two lines of credit. See Note 11.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company evaluates goodwill for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. Because the Company has one reporting unit, the Company utilizes the entity-wide approach to assess goodwill for impairment. No impairment has been recorded through June 30, 2011.

Intangible Assets, Net

Intangible assets, net consist of intangible assets acquired from other companies as a result of acquisitions. Such assets are capitalized and amortized on a straight-line basis over the estimated useful life of the intangible assets. Intangible assets, net excludes patent related intangible assets, which are recorded within patent assets, net in the accompanying consolidated balance sheets.

Internal-Use Software and Website Development Costs

For its website development costs and the development costs related to other internal-use software, the Company capitalizes costs incurred during the application development stage, and reflects such amounts within the property and equipment, net line item on the consolidated balance sheets. Costs related to preliminary project activities, minor enhancement and maintenance and post implementation activities are expensed as incurred. Internal-use software is generally amortized on a straight-line basis over three years beginning on the date the software is placed into service. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

For the three and six months ended June 30, 2011, the Company capitalized $0.4 million and $0.6 million of software development costs, respectively. No amount was capitalized for either the three or six months ended June 30, 2010. Amortization of internal-use software was $23,000 for both the three and six months ended June 30, 2011. There was no amortization of internal-use software for either the three or six months ended June 30, 2010.

Comprehensive Income

Comprehensive income consists of net income and charges or credits to stockholders’ equity primarily related to changes in unrealized gains or losses on marketable securities, net of taxes. For the periods presented, the Company’s comprehensive net income approximates its net income, therefore no separate components of comprehensive income are provided.

Recent Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2011-05, “Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 is effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early adoption is permitted. The adoption of this guidance is not expected to have material impact on the Company’s consolidated financial position, results of operations, or cash flows.

In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS” (“ASU 2011-04”). The amendments in ASU 2011-04 result in common fair value measurement and disclosure requirements in U.S. GAAP and IFRS. Consequently, ASU 2011-04 changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. For many of the requirements, the FASB does not intend for the amendments in ASU 2011-04 to result in a change in the application of the requirements in Topic 820. ASU 2011-04 is effective prospectively for interim and annual reporting periods beginning after December 15, 2011. The adoption of this guidance is not expected to have material impact on the Company’s consolidated financial position, results of operations, or cash flows.

In December 2010, the FASB issued ASU 2010-29, “Disclosure of Supplementary Pro Forma Information for Business Combinations” (“ASU 2010-29”). ASU 2010-29 amends and clarifies the acquisition date to be used for reporting pro forma financial disclosures when comparative financial statements are presented. In addition, it requires a description of the nature of and amount of any material, non-recurring pro forma adjustments directly attributable to the business combination. ASU 2010-29 is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The Company adopted this amendment effective January 1, 2011. There was no impact on the Company’s consolidated financial position, results of operations, or cash flows.

In December 2010, the FASB issued ASU 2010-28, “When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts” (“ASU 2010-28”). ASU 2010-28 modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance which requires that goodwill of a reporting unit be tested for impairment 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 amount. This ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2010. The Company adopted this amendment effective January 1, 2011. There was no impact on the Company’s consolidated financial position, results of operations, or cash flows.

2. Acquisition of Business

On June 1, 2011, RPX acquired substantially all of the assets of a patent research and intellectual property news provider for $3.0 million in cash. The acquisition expands RPX’s market intelligence and data analysis capabilities. The acquisition has been accounted for as a business combination. Identifiable intangible assets acquired were recorded at fair value as of the acquisition date. No cash or tangible assets were acquired and no liabilities assumed. Acquisition-related costs of $43,000 were expensed during the three months ended June 30, 2011.

Under business combination accounting, the total purchase price was allocated to the acquired company’s identifiable intangible assets based on their estimated fair values as of June 1, 2011 with remainder recorded as goodwill. Approximately $1.7 million of goodwill and $1.3 million of identifiable intangible assets were allocated in connection with the acquisition. The goodwill primarily relates to cost benefits and operational synergies realized by applying the research capabilities inherent in the acquired company’s business to other data and research systems at RPX. The acquired goodwill of $1.7 million is deductible for U.S. federal income tax purposes.

RPX included the effect of the transaction in its results of operations prospectively from the date of the acquisition. Pro forma financial information for the acquisition has not been presented, as the effects were not material to RPX’s historical consolidated financial statements.

3. Net Income Attributable to Common Stockholders

Basic and diluted net income per share attributable to common stockholders are presented in conformity with the two-class method required for participating securities. Holders of shares of Series A, Series A-1, Series B and Series C redeemable convertible preferred stock are each entitled to receive 8% per annum non-cumulative dividends, payable prior and in preference to any dividends on common stock. In addition, the holders of restricted common stock are entitled to receive non-forfeitable dividends if declared.

Under the two-class method, basic net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period non-cumulative dividends attributable to shares of Series A, Series A-1, Series B and Series C redeemable convertible preferred stock, among common stockholders, restricted stockholders and Series A, Series A-1, Series B and Series C redeemable convertible preferred stockholders. Diluted net income per share attributable to common stockholders is computed by using the weighted average number of shares of common stock outstanding, including potential dilutive shares of common stock, assuming the dilutive effect of outstanding stock options and unvested restricted stock units using the treasury stock method.

The following table presents the calculation of basic and diluted net income per share attributable to common stockholders (in thousands, except per share data):

	Three Months Ended June 30,				Six Months Ended June 30,
	2011		2010		2011		2010

For the three and six months ended June 30, 2011 and 2010, the following securities were not included in the calculation of diluted shares outstanding, as the effect would have been anti-dilutive (in thousands):

	Three Months Ended June  30,				Six Months Ended June 30,
	2011		2010		2011		2010
Weighted average number of shares of redeemable convertible preferred stock		11,241		25,741		18,694		25,741
Weighted average number of shares of common stock subject to repurchase		3,505		5,865		3,741		6,165

4. Fair Value Measurements

The Company’s financial assets are valued using market prices on both active markets (“Level 1”) and less active markets (“Level 2”). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments. As of June 30, 2011 and December 31, 2010, the Company did not have any financial assets without observable market values that would require a high level of judgment to determine fair value (“Level 3”).

The following tables present the financial assets measured at fair value on a recurring basis as of June 30, 2011 and December 31, 2010 (in thousands):

	June 30, 2011
	Total Balance		Level 1		Level 2

Structured Acquisitions

Structured acquisitions are transactions involving patent assets that cost more than the Company is prepared to spend with its own capital resources or that are relevant only to a very small number of clients. In such transactions, the Company works to acquire these assets with financial assistance from the particular clients against whom the assets are being or may be asserted. When this occurs, the participating clients typically pay amounts separate from their subscription fees and receive an immediate perpetual license to the acquired patent assets. The Company may treat the payments received from the participating clients as revenue either on a gross or a net basis depending on the specific facts and circumstances of the transaction. In the event that such payments are recognized on a net basis, the Company will capitalize the acquired asset that relates to its non-participating clients. In such instance, the cost basis of the acquired patent rights excludes the amounts paid by the participating client.

Barter Transactions

The Company accounts for non-monetary exchanges in accordance with ASC 845, Non-monetary Transactions (“ASC 845”), which requires non-monetary exchanges to be based on the fair value of the assets or services involved.

During the six months ended June 30, 2011, the total fair value of intangible assets exchanged for subscription services was approximately $120,000. No gain or loss was recorded as a result of this exchange. There were no barter transactions during the three or six months ended June 30, 2010.

Litigation

From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with its legal counsel, the need to record a liability for litigation. A liability is recorded when and if it is determined that such a liability for litigation is both probable and reasonably estimable. As of June 30, 2011, the Company was not a party to any litigation and no liabilities for litigation have been accrued.

Other Commitments and Contingencies

On September 10, 2010, the Company entered into certain agreements with a special-purpose entity formed for the sole purpose of acquiring specific patent assets that had been made available for sale by a third party.

As of June 30, 2011, the third party had completed the sale of the assets and the special-purpose entity was not the buyer. Therefore, no investment in such entity has been made and the Company has no further obligations under these agreements.

On December 12, 2008, in connection with the acquisition of certain patent assets from an unaffiliated third party in an arm’s-length transaction, the Company agreed to make a one-time payment of $5.0 million in the event that the Company earns $170.0 million of annual subscription revenues in any calendar year. No provision has been made for this contingency as of June 30, 2011.

14. Equity Award Plans

On February 23, 2011, the Board of Directors adopted the 2011 Equity Incentive Plan (the “2011 Plan”), which became effective in May 3, 2011, the date of the Company’s IPO. The 2011 Plan provides for the issuance of incentive stock options, non-qualified stock options, stock appreciation rights, restricted shares of the Company’s common stock, and stock units to employees, directors and consultants. The Board of Directors reserved 1,500,000 shares of common stock for future issuance under the 2011 Plan.

On August 11, 2008, the Board of Directors adopted the 2008 Stock Option Plan (the “2008 Plan”), which provides for the issuance of incentive stock options, non-qualified stock options, as well as the direct award or sale of shares of common stock to employees, directors and consultants for up to 9,019,474 shares of common stock, as amended. No further awards will be made under the 2008 Plan; however, all awards outstanding under the 2008 Plan will continue to be governed by the existing terms.

Under both the 2008 Plan and 2011 Plan, incentive stock options and non-qualified stock options are to be granted at a price not less than 100% of the fair value of the stock at the date of grant. Options granted to newly hired employees vest 25% on the first anniversary of the date of hire and ratably each month over the ensuing 36-month period. Options granted to existing employees generally vest ratably over the 48 months following the date of grant. Options are exercisable for a maximum period of ten years after date of grant. Incentive stock options granted to stockholders who own more than 10% of the outstanding stock of the Company at the time of grant must be issued at an exercise price not to be less than 110% of the fair value of the stock on the date of grant.

As of June 30, 2011 there were 1,469,234 shares available for grant under the 2011 Plan.

Stock Options

The total stock options outstanding are summarized as follows:

	Number of Options			Weighted- Average Exercise Price

Stock-Based Compensation Related to Employees and Non-Employee Directors

The Company estimates the fair value of stock options using the Black-Scholes option pricing model. Option valuation models, including the Black-Scholes option pricing model, require the input of various assumptions, including stock price volatility. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. The weighted average assumptions and resulting fair values were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2011			2010			2011			2010
Risk-free interest rate		2.38	%		2.57	%		2.58	%		2.69	%
Expected volatility		58	%		60	%		58	%		60	%
Expected dividend yield		—			—			—			—
Expected term (years)		5.9			6.0			6.5			6.0
Weighted average estimated fair value	$	11.26		$	1.43		$	7.41		$	1.32

For Restricted Stock Units (RSUs), stock-based compensation expense was calculated based on the Company’s stock price on the date of grant, multiplied by the number of units granted. The grant date fair value of RSUs, less estimated forfeitures, is recognized on a straight-line basis over the requisite service period.

Stock-based compensation expense related to employees was $1.3 million and $2.1 million, for the three and six months ended June 30, 2011, respectively. Stock compensation expense related to employees was $146,000 and $283,000, for the three and six months ended June 30, 2010, respectively. Stock-based compensation of $17,000 and $29,000 was capitalized during the three and six months ended June 30, 2011, respectively, as part of the cost of internal-use software. No stock-based compensation expense was capitalized during the three or six months ended June 30, 2010.

Stock-based compensation expense is recognized ratably over the requisite service period. At June 30, 2011, there was $18.6 million of unrecognized compensation cost related to options which is expected to be recognized over a weighted average period of 3.9 years. At June 30, 2011, there was $1.8 million of unrecognized compensation cost related to RSUs which is expected to be recognized over a weighted average period of 3.8 years. Future option grants will increase the amount of stock-based compensation expense to be recorded.

Stock-Based Compensation Related to Non-Employees

The Company periodically grants options to non-employees in exchange for goods and services. During the six months ended June 30, 2011, the Company issued 10,000 shares of common stock and options to purchase 35,000 shares of common stock to non-employees in exchange for services. No awards were granted to non-employees in exchange for goods and services during the six months ended June 30, 2010.

Stock-based compensation expense related to non-employees was $0.6 million and $0.8 million for the three and six months ended June 30, 2011, respectively. Stock-based compensation expense related to non-employees was $46,000 and $66,000 for the three and six months ended June 30, 2010, respectively. The Company accounts for these stock options using the variable accounting model and re-measures them each accounting period.

15

15. Income Taxes

The Company uses an estimated annual effective tax rate based upon a projection of its annual fiscal year results to measure the income tax benefit or expense recognized in each interim period. Our effective tax rate for the six months ended June 30, 2011 was 42.8% compared to 41.9% for the six months ended June 30, 2010. The higher effective tax rate for the six months ended June 30, 2011 was primarily due to an increase in stock-based compensation. The difference between the consolidated effective income tax rate and the U.S. federal statutory rate is primarily attributable to the effect of certain permanent differences and state income taxes.

Tax years 2009 and 2008 are currently under examination by the United States Internal Revenue Service and the State of California Franchise Tax Board. The Company does not expect a material impact on its consolidated financial statements as a result of these examinations.

16. Related Party Transactions

Two of the Company’s directors also serve on the boards of directors of RPX clients. For the three and six months ended June 30, 2011, the Company recognized subscription fee revenue of $0.7 million and $1.3 million, respectively, related to these clients. For the three and six months ended June 30, 2010, the Company recognized subscription fee revenue of $0.7 million and $1.3 million, respectively, related to these clients. As of June 30, 2011 and December 31, 2010, there were no receivables due from either of these clients.

In April 2011, the Company sold an aggregate of 105,708 shares of its common stock at a price of $14.19 per share to two members of its Board of Directors.

17. Segments

Operating segments are components of an enterprise about which separate financial information is available. Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its chief executive officer. The Company’s chief executive officer reviews financial information presented on a consolidated basis and, as a result, the Company concluded that there is only one operating and reportable segment.

The Company markets its solution to companies around the world. Revenue is generally attributed to geographic areas based on the country in which the customer is domiciled.

Overview

RPX helps companies reduce patent-related risk and expense. We provide a subscription-based patent risk management solution that facilitates more efficient exchanges of value between owners and users of patents compared to transactions driven by actual or threatened litigation. As of June 30, 2011, we had a client network of 96 members.

The core of our solution is defensive patent aggregation, in which we acquire patents or licenses to patents, which we refer to collectively as “patent assets,” that are being or may be asserted against our current and prospective clients. We then license these patent assets to our clients to protect them from potential patent infringement assertions. We also provide our clients access to our proprietary patent market intelligence and data. As of June 30, 2011, we had deployed over $300 million to acquire patent assets.

Our business model aligns our interests with those of our clients. We have not asserted and will not assert our patents, which enables us to develop strong and trusted relationships with our clients. Our clients include companies that design, make or sell technology-based products and services as well as companies that use technology in their businesses.

For the three and six months ended June 30, 2011, revenue grew to $38.9 million and $73.2 million, respectively, as we added 15 and 24 net new clients, respectively, bringing our total client network to 96 companies. We ended the quarter with deferred revenue of $87.6 million.

We believe that the amount that we spend to acquire patent assets is a key driver of the value that we create for our clients. We measure acquisition spend on both a “gross” and a “net” basis, whereby the “gross spend” represents the aggregate amount spent including amounts contributed by our clients in syndicated acquisitions above and beyond their subscription fees and the “net spend” represents only the net incremental investment of our own capital. During the three and six months ended June 30, 2011 we completed 8 and 15 acquisitions of patent assets, respectively, and our gross acquisition spend totaled $21.7 million and $41.2 million, respectively. None of these were syndicated acquisitions and thus our net acquisition spend was the same as our gross acquisition spend. Over the four quarters ending June 30, 2011, our gross acquisition spend totaled $84.3 million and our net acquisition spend totaled $70.5 million.

On May 3, 2011, our registration statement on Form S-1 relating to the IPO of our common stock was declared effective by the SEC. The IPO closed in May 2011, at which time we sold 9,065,000 shares of our common stock and received cash proceeds of $160.2 million, net of underwriting discounts and commissions.

Key Components of Results of Operations

Revenue

Historically, substantially all of our revenue has consisted of annual subscription fees. We expect that subscription fee revenue will increase with the growth of our client network. Subscription revenue will be positively or negatively impacted by the financial performance of our clients since their subscription fees are typically reset yearly based upon their most recently reported annual financial results. We have also received revenue from the sale of licenses and fee income in connection with structured acquisitions. We have and in the future may receive other revenue and fee income from newly-introduced products and services.

Cost of Revenue

Cost of revenue primarily consists of amortization expenses related to acquired patent assets. Acquired patent assets are capitalized and amortized ratably over the shorter of their estimated useful lives or the remaining statutory life. Also included in the cost of revenue are the expenses incurred to maintain and prosecute patents and patent applications. We expect our cost of revenue to increase in the future as we add additional patent assets to our existing portfolio to support our existing and future clients.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist of salaries and related expenses, including stock-based compensation expenses, cost of marketing programs, certain legal costs, professional fees, travel costs, facility costs and other corporate expenses. We expect that in the future, as we seek to serve more clients and develop new products and services, selling, general and administrative expenses will increase. Selling, general and administrative expenses will also increase in order to support our operations and compliance requirements as a public company.

Interest Income and Expense

Interest income represents interest earned on cash balances and short-term investments. Interest expense is incurred on our debt obligations mainly resulting from financed patent asset acquisitions. We expect interest income to fluctuate in the future due to changes in our cash, cash equivalents and investment balances and market interest rates. Interest expense will fluctuate due to changes in our debt obligation balances.

Provision for Income Taxes

Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Based on available information, we believe it is more-likely-than-not that our deferred tax assets will be fully realized.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses and related disclosures. There have been no material changes to our critical accounting policies and estimates as compared to those described in our prospectus filed pursuant to Rule 424(b) under the Securities Act with the SEC on May 4, 2011.

We consider the following to be critical accounting policies and estimates because we believe they are both important to the portrayal of our financial condition and results of operations and they require management judgments about matters that are uncertain. If actual results or events differ materially, our reported financial condition and results of operation for future periods could be materially affected.

• Revenue Recognition

• Amortization of Patent Assets

• Accounting for Stock-Based Awards

• Accounting for Income Taxes

Revenue. Our revenue for the three months ended June 30, 2011 increased by $17.0 million or 78% to $38.9 million compared to the same period a year ago. Revenue for the six months ended June 30, 2011 increased by $33.2 million or 83% to $73.2 million compared to the same period a year ago. The increases for both the three and six months ended June 30, 2011 were primarily due to the growth in our client network and the resulting recognition of revenue from clients that joined both during the period and prior to the start of the period. Revenue included $3.3 million from the sale of a perpetual license in the three and six months ended June 30, 2011 as compared to $0.5 million in the same periods in 2010.

We expect our revenue growth to continue if we are successful in our efforts to add new clients and retain existing clients. However, while we expect to continue to experience revenue growth, we do not believe that our rate of growth since inception is representative of anticipated future revenue growth.

Cost of Revenue. Our cost of revenue for the three months ended June 30, 2011 increased by $4.3 million or 42% to $14.5 million compared to the same period a year ago. Cost of revenue for the six months ended June 30, 2011 increased by $10.2 million or 57% to $28.2 million compared to the same period a year ago. The increases for both the three and six months ended June 30, 2011 were primarily the result of additional amortization expense recorded from patent assets acquired in 2010 and during the three and six months ended June 30, 2011. The expenses incurred to maintain patents and prosecute patent applications included in our portfolio were approximately $0.2 million for both the three months ended June 30, 2011 and 2010. The expenses incurred to maintain patents and prosecute patent applications included in our portfolio were approximately $0.3 million and $0.4 million for the six months ended June 30, 2011 and 2010, respectively.

20

Selling, General and Administrative Expenses. Our selling, general and administrative expenses for the three months ended June 30, 2011 increased by $6.1, million or 117%, to $11.3 million compared to the same period a year ago. The increase was primarily due to a $4.4 million increase in personnel-related costs attributable to increased headcount and increased stock-based compensation expense when compared to the prior year. We had 81 employees at June 30, 2011 compared to 43 employees at June 30, 2010. Our legal and professional fees for the three months ended June 30, 2011 increased by $1.0 million due primarily to $0.7 million of increased legal costs and $0.3 million in increased accounting fees compared to the same period a year ago. Our facility-related costs, depreciation and other corporate expenses for the three months ended June 30, 2011 increased by $0.6 million to support the growth of our business, including leasing of additional office space compared to the same period a year ago.

Our selling, general and administrative expenses for the six months ended June 30, 2011 increased by $9.9 million or 105% to $19.4 million compared to the same period a year ago. The increase from the prior year was primarily due to a $6.9 million increase associated with personnel related costs and increased stock-based compensation expense as noted above. Our legal fees increased by $0.7 million and professional fees increased by $0.8 million for the six months ended June 30, 2011. Our patent asset related acquisition costs for the six months ended June 30, 2011 increased by $0.7 million compared to the same period a year ago. Our facility-related costs, depreciation and other corporate expenses for the six months ended June 30, 2011 also increased by $1.1 million to support the growth of our business, including leasing of additional office space and costs associated with being a public company compared to the same period a year ago.

In August 2010, we launched our Client Relations team, which is focused on building deep relationships throughout our clients’ organizations, both to ensure that our clients’ current needs are being met and to serve as the vehicle for marketing additional, value-added patent risk management solutions. In September 2010, we opened our Tokyo office to facilitate our development and management of client relationships with companies located in Asia. Also in 2010, we established our Corporate Development team, which is responsible for developing new products and services. We expect that our selling, general and administrative expenses will increase in future periods as we continue to invest in the growth of our business and incur costs associated with being a public company. We anticipate that such expenses will increase more rapidly than the growth of our revenue in 2011.

Interest Income and Expense. Interest income for the three months ended June 30, 2011 decreased by $25,000, or 37%, to $42,000 compared to the same period a year ago. Interest income for the six months ended June 30, 2011 decreased by $0.1 million, or 66%, to $68,000 compared to the same period a year ago. The decreases for both the three and six months ended June 30, 2011 were primarily due to a reduction in interest bearing notes receivable.

Interest expense for the three months ended June 30, 2011 decreased by $0.6 million or 70%, to $0.2 million compared to the same period a year ago. Interest expense, for the six months ended June 30, 2011 decreased by $1.1 million, or 64%, to $0.6 million compared to the same period a year ago. The decreases for both the three and six months ended June 30, 2011 were primarily due to a reduction in outstanding debt balances.

Provision for Income Taxes. Our provision for income taxes for the three months ended June 30, 2011 increased by $2.8 million or 116%, to $5.2 million compared to the same period a year ago. The provision for income taxes for the six months ended June 30, 2011 increased by $6.1 million or 131%, to $10.7 million compared to the same period a year ago. The overall increases in income tax expenses for both the three and six months ended June 30, 2011 were due to our higher income before taxes.

Our effective tax rate for the six months ended June 30, 2011 was 42.8% compared to 41.9% for the six months ended June 30, 2010. The higher effective tax rate for the six months ended June 30, 2011 was primarily due to an increase in stock-based compensation. The difference between the consolidated effective income tax rate and the U.S. federal statutory rate is primarily attributable to the effect of certain permanent differences and state income taxes.

Liquidity and Capital Resources

In May 2011, we completed our IPO in which we issued 9,065,000 common shares and received cash proceeds of $160.2 million, net of underwriting discounts and commissions. We incurred offering costs of $2.9 million. Prior to the IPO, substantially all of our operations and patent asset acquisitions had been financed through the private sale of equity securities, subscription fees collected from our clients and patent-seller financing.

As of June 30, 2011, we had $159.4 million of cash and cash equivalents and $39.3 million in short-term investments. Through June 30, 2011, we had raised $64.4 million in a series of equity financings from venture capital firms and other investors. We raised $25.3 million in connection with our sale of Series A and Series A-1 redeemable convertible preferred stock in August 2008 through December 2008, $35.3 million in connection with our sale of Series B redeemable convertible preferred stock in July 2009 and $3.8 million in connection with our sale of Series C redeemable convertible preferred stock in November 2010. All of the proceeds from our sale of Series C redeemable convertible preferred stock were used to repurchase shares owned by certain of our employees.

21

We believe our existing cash, cash equivalents, short-term investments and contractual payments due to us from existing clients will be sufficient to meet our working capital and capital expenditure needs for the foreseeable future. Our future capital needs will depend on many factors, including, among other things, our acquisition of patent assets, addition and renewal of clients, development of new solutions and performance of general and administrative activities. We anticipate an increased level of patent acquisition spending for the remainder of 2011 as our business grows. Additionally, we may enter into potential investments in, or acquisitions of, complementary businesses which could require us to seek additional debt or equity financing. Additional funds may not be available on terms favorable to us or at all.

We will also incur costs as a public company that we have not previously incurred, including, but not limited to, costs and expenses for directors fees, increased directors’ and officers’ insurance, investor relations fees, expenses for compliance with the Sarbanes-Oxley Act of 2002 and rules implemented by the SEC and The Nasdaq Global Select Market and various other costs. The Sarbanes-Oxley Act of 2002 requires that we maintain effective disclosure controls and procedures and internal control over financial reporting.

The following table sets forth a summary of our cash flows for the periods indicated (in thousands):

	Six Months Ended June 30,
	2011			2010
Net cash provided by operating activities	$	55,087		$	74,669
Net cash used in investing activities		(86,002	)		(43,158	)
Net cash provided by (used in) financing activities		143,652			(20,367	)
Net increase in cash and cash equivalents		112,737			11,144

Cash Flows from Operating Activities

Cash provided by operating activities primarily consists of net income adjusted for certain non-cash items including depreciation, amortization, stock-based compensation and the effect of changes in working capital and other activities. Cash provided by operating activities for the six months ended June 30, 2011 was $55.1 million, consisting of net income of $14.4 million, adjustments for non-cash items of $31.6 million and changes in working capital and non-current assets and liabilities totaling $9.2 million. The change in working capital resulted primarily from a decrease in accounts receivable of $6.4 million and an increase in deferred revenue of $5.0 million. The increase in deferred revenue for the six months ended June 30, 2011 is primarily attributable to $78.2 million of subscription billings for the period offset by $73.2 million of revenue recognized during the period. The increase in deferred revenue is due to annual subscription billings and the growth in our membership to 96 clients as of June 30, 2011 from 72 clients as of December 31, 2010. The amount of deferred revenue in any given period varies with the addition of new clients, the mix of payment terms that we offer and the timing of invoicing existing clients.

Cash provided by operating activities for the six months ended June 30, 2010 was $74.7 million and consisted of net income of $6.4 million, adjustments for non-cash items of $19.0 million and $49.2 million provided by changes in working capital and non-current assets and liabilities. The change in working capital resulted primarily from a decrease in accounts receivable of $3.5 million and an increase in deferred revenue of $42.7 million. The increase in deferred revenue during the six months ended June 30, 2010 is attributable to $82.7 million of subscription billings for the period offset by $40.0 million of revenue recognized during the period. The increase in deferred revenue is due to the growth in our membership from 23 clients as of December 31, 2009 to 51 clients as of June 30, 2010.

Cash Flows from Investing Activities

Cash used in investing activities primarily consists of acquisitions of patent assets and purchases of short-term marketable securities classified as available-for-sale. Net cash used in investing activities for the six months ended June 30, 2011 was $86.0 million, of which $43.2 million represented our acquisitions of patent assets and $39.1 million represented our net purchases of short-term marketable securities. On June 1, 2011, we acquired substantially all of the assets of a patent research and intellectual property news provider for $3.0 million.

We expect our cash used in investing activities to increase in the future as we acquire additional patents. Cash used by investing activities for the six months ended June 30, 2010 was $43.2 million and primarily consisted of our acquisitions of patent assets of $43.0 million.

Cash Flows from Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2011 was $143.7 million. Net cash provided by financing activities during the six months ended June 30, 2011 was due primarily to proceeds from our IPO, net of issuance costs of approximately $157.8 million, offset by the repayment of $16.4 million of debt and other obligations. Net cash used in the financing activities for the six months ended June 30, 2010 was $20.4 million, the majority of which represented the repayment of debt obligations.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency exchange rates and interest rates. We do not hold or issue financial instruments for trading purposes.

Foreign Currency Exchange Risk

Our subscription agreements are denominated in U.S. dollars, and therefore, our revenue is not currently subject to significant foreign currency risk. Our expenses are incurred primarily in the United States, with a small portion of expenses incurred and denominated in the currencies where our other international offices are located. Our results of operations and cash flows are therefore subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Japanese Yen relative to the U.S. dollar. To date, we have not entered into any foreign currency hedging contracts.

Interest Rate Sensitivity

We had cash, cash equivalents and restricted cash of $160.1 million at June 30, 2011. Cash equivalents are primarily invested in bank deposits and money market funds denominated primarily in U.S. dollars. Interest rate fluctuations affect the returns in our invested funds. The Company’s cash balances deposited in U.S. banks are non-interest bearing and insured up to the Federal Deposit Insurance Corporation limits. Cash and cash equivalents are held for working capital purposes and restricted cash amounts are held as security against credit card deposits and various lease obligations.

At June 30, 2011, we also had $39.3 million held in short-term investments, primarily invested in U.S. Government and Agency securities with maturities between 90 days and 13 months. As of June 30, 2011, our investments have been classified as available-for-sale and, consequently, are recorded at fair value in the consolidated balance sheet with unrealized gains or losses reported as a separate component of stockholders’ equity. We review our investments for impairment when events and circumstances indicate a decline in fair value of such assets below carrying value is other-than-temporary. As of June 30, 2011, we have not recorded an impairment related to our investments in the consolidated statement of operations.

If overall interest rates had changed by 10% during the three or six months ended June 30, 2011, the fair value of our investments would not have been materially affected.

Effect of Inflation

We believe that inflation has not had a material impact on our consolidated results of operations for the three and six months ended June 30, 2011. There can be no assurance that future inflation will not have an adverse impact on our consolidated results of operations or financial condition.

Fair Value of Financial Instruments

We do not have material exposure to market risk with respect to investments, as our investments consist primarily of highly liquid investments that approximate their fair values due to their short period of time to maturity. We do not use derivative financial instruments.

24

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2011. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Based on the evaluation of our disclosure controls and procedures as of June 30, 2011, our Chief Executive Officer and Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Limitations on Controls

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives as specified above. Our management does not expect, however, that our disclosure controls and procedures will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all of our control issues and instances of fraud, if any, have been detected.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the period covered by this quarterly report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors

Risks Related to Our Business

27

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should consider carefully the risks and uncertainties described below before making a decision to buy our common stock. If any of the following risks actually occur, our business, financial condition, results of operations or growth prospects could be harmed. In that case, the trading price of our common stock could decline and you could lose all or part of your investment in our common stock. The risks described below are not the only risk facing us. Risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and operating results. When making your investment decision, you should also refer to the other information set forth in this Form 10-Q, including our consolidated financial statements and the related notes, and our prospectus filed with the SEC on May 4, 2011.

Risks Related to Our Business and Industry

Our limited operating history makes it difficult to evaluate our current business and future prospects, and potential clients may have concerns regarding the effectiveness in the future of our business model. If companies do not continue to subscribe to our solution, our business and operating results will be adversely affected.

We were incorporated in July 2008. We acquired our first patent assets in September 2008 and sold our first membership in October 2008. Therefore, we have not only a very limited operating history, but also a very limited track record in executing our business model. Our future success depends on acceptance of our solution by companies we target to become clients. Our efforts to sell our solution to new companies may not continue to be successful. In particular, because we are a relatively new company with a limited operating history, companies may have concerns regarding our viability. Our limited operating history may also make it difficult to evaluate our current business and future prospects. We have encountered and will continue to encounter risks and difficulties frequently experienced by companies in rapidly changing industries. If we do not manage these risks successfully, our business and operating results will be adversely affected.

We may experience significant quarterly fluctuations in our operating results due to a number of factors, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations.

Due to our limited operating history, our evolving business model and the unpredictability of our emerging industry, certain of our operating results have fluctuated significantly in the past and may fluctuate significantly in the future. Many of the factors that cause these fluctuations are outside of our control. The amount we spend to acquire patent assets and the timing of those acquisitions may result in significant quarterly fluctuations in our capital expenditures, and the amount and timing of our membership sales may result in significant fluctuations in our cash flow on a quarterly basis. As a result, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance.

In addition to the factors described above, other factors that may affect our operating results include:

• increases in the prices we need to pay to acquire patent assets;

• increases in operating expenses, including those attributable to additional headcount and the costs of new business initiatives;

• non-renewals from existing clients for any reason;

• loss of clients, including through acquisitions or consolidations;

• changes in our subscription fee rates or the pricing policies of our competitors;

• our inability to acquire patent assets that are being asserted or may be asserted against our clients due to lack of availability, unfavorable pricing terms or otherwise;

• changes in patent law and regulations and other legislation, as well as United States Patent and Trademark Office procedures or court rulings, that reduce the value of our solution to our existing and potential clients;

• our lengthy and unpredictable membership sales cycle, including delays in potential clients’ decisions whether to subscribe to our solution;

• changes in the accounting treatment associated with our acquisitions of patent assets, how we amortize those patent assets and how we recognize revenue under subscription agreements;

• lower subscription fees from clients where the annual subscription fee decreases due to declining operating income or revenue of such clients;

28

• our inability to develop and implement new solutions that meet client requirements in a timely manner;

• decreases in our clients’ and prospective clients’ costs of litigating patent infringement claims;

• our inability to retain key personnel;

• any significant changes in the competitive dynamics of our market, including new competitors or substantial discounting of services that are viewed by our target market as competitive to ours;

• gains or losses realized as a result of our selling patents, including upon the exercise by any of our clients of their limited right to purchase certain of our patent assets for defensive purposes in the event of a patent infringement suit brought against such client by a third party; and

• adverse economic conditions in the industries that we serve, particularly as they affect the intellectual property risk management and/or litigation budgets of our existing or potential clients.

While we have not experienced seasonality trends to date, we anticipate that we may experience lower new client additions in the third quarter of the year due to vacation schedules of the executive management of many of our prospective clients. If our operating results in a particular quarter do not meet the expectations of securities analysts or investors, our stock price could be substantially affected. In particular, if our operating results fall below expectations, our stock price could decline substantially.

The market for our patent risk management solution is immature, and if our solution is not widely accepted or is accepted more slowly than we expect, our operating results will be adversely affected.

We have derived substantially all of our revenue from the sale of memberships to our patent risk management solution and we expect this will continue for the foreseeable future. As a result, widespread acceptance of this solution is critical to our future success. The market for patent risk management solutions is new and it is uncertain whether these solutions will achieve and sustain high levels of demand and market acceptance. Our success will depend, to a substantial extent, on the willingness of companies of all sizes to purchase and renew memberships as a way to reduce their patent litigation costs. If companies do not perceive the cost-savings benefits of patent risk management solutions, then wide market adoption of our solution will not develop, or it may develop more slowly than we expect. Either scenario would adversely affect our operating results in a significant way. Factors that may negatively affect wide market acceptance of our solution, as well as our ability to obtain new clients and renew existing clients, include:

• uncertainty about our ability to significantly reduce patent litigation costs for a particular company;

• reduced assertions from non-practicing entities (“NPEs”) or decreased patent licensing fees owed to NPEs;

• limitations on the ability of NPEs to bring patent claims or limitations on the potential damages recoverable from such claims;

• reduced cost to our clients of defending patent assertion claims;

• lack of perceived relevance and value in our existing patent asset portfolio by existing or potential clients;

• concerns by existing or potential clients about our future ability to obtain rights to patent assets that are being or may be asserted against them;

• reduced incentives to renew memberships if clients have vested in perpetual licenses in all patent assets that they believe are materially relevant to their businesses;

• lack of sufficient interest by mid-and small-sized companies in our solution;

• reduced incentive for companies to become clients because we do not assert our patent assets in litigation;

• concerns that we might change our current business model and assert our patent assets in litigation;

• budgetary limitations for existing or potential clients; and

• the belief that adequate coverage for the risks and expenses we attempt to reduce is available from alternative products or services.

29

We have limited experience with respect to our subscription pricing model, and if the prices we charge for memberships are unacceptable to our existing or potential clients, our revenue and operating results could experience volatility or decline.

We have limited experience with respect to determining the appropriate metrics for establishing the annual subscription fees for our patent risk management solution. If the market for our solution fails to develop or develops more slowly than we anticipate, or if competitors introduce new solutions that compete with ours, we may be unable to renew our memberships or attract new clients at favorable prices based on the same pricing model we have historically used. In the future, it is possible that competitive dynamics in our market may require us to change our pricing model or reduce our subscription fee rates, which could harm our operating results. We began introducing a new fee schedule with higher fees in January 2011. This higher cost of membership may make it more difficult for us to attract new clients in the future. In order to attract clients, in certain cases we have previously offered, and may in the future offer, discounts or other contractual incentives to clients who execute multi-year subscription agreements or who make client referrals.

We have very limited flexibility to change the pricing of our solution for existing clients and may not be able to respond effectively to changes in our market. This limited flexibility could have an adverse effect on our operating results.

Under our subscription agreements, our annual subscription fee is based on a published fee schedule applicable to all of our clients that join our network while that fee schedule is in effect. Clients are able to renew their memberships perpetually under the fee schedule in effect at the time that they joined our network with periodic adjustments by us only based on changes in the Consumer Price Index. This means that any increases to our fee schedule apply only to clients that join after such increase. Accordingly, we have limited ability to change the economics of our business model with respect to existing clients in response to changes in the market in which we operate. This limited flexibility could have an adverse effect on our operating results. For example, if we increase our operating expenses as a result of changes in our market, we would have very limited ability to increase the subscription fees we charge to our existing clients as an offset to the increased operating expenses, and our operating results could be adversely affected.

Our membership sales cycles can be long and unpredictable, and our membership sales efforts require considerable time and expense. As a result, our membership sales are difficult to predict and will vary substantially from quarter to quarter, which may cause our cash flow to fluctuate significantly.

Because we operate in a relatively new and unproven market, our membership sales efforts involve educating potential clients about the benefit of our solution, including potential cost savings to a company. Potential clients typically undergo a lengthy decision-making process that has, in the past, generally resulted in a lengthy and unpredictable sales cycle. We spend substantial time, effort and resources in our membership sales efforts without any assurance that our efforts will produce any membership sales. In addition, subscriptions are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. As a result of these factors, our membership sales in any period are difficult to predict and will likely vary substantially between periods, which may cause our cash flow to fluctuate significantly between periods.

The success of our business will increasingly depend on clients renewing their subscription agreements, but we do not have an adequate operating history to predict the rate of membership renewals. Any significant decline in our membership renewals could harm our operating results.

Our clients have no obligation to renew their subscriptions after the expiration of their initial membership period. We have limited historical data with respect to rates of subscription renewals, so we cannot accurately predict renewal rates. The weighted average term of our subscription agreements in effect as of June 30, 2011 was 2.8 years. As our overall membership base grows, we expect our renewal rate to decline compared to our historical rate. Our clients may choose not to renew their memberships or, if they do renew, may choose to do so for shorter terms or seek a reduced subscription fee. Many of our subscription agreements provide for automatic one-year renewal periods. As a result, as more of our clients are in renewal periods, the weighted average term of our subscription agreements may decrease. If our clients do not renew their subscriptions or renew for shorter terms or if we allow them to renew at reduced subscription fees, our revenue may decline and our business may be adversely affected.

Upon initial subscription, our clients receive a term license for the period of their membership to the patent assets in our portfolio at the time of subscription. In addition, clients receive term licenses to substantially all of the patent assets we acquire during the period of their membership. Our subscription agreements also include a vesting provision that converts a client’s term licenses into perpetual licenses on a delayed, rolling basis as long as the company remains a client. Accordingly, clients who continue to subscribe to our solution receive perpetual licenses to an increasing number of our patent assets over time. If we are unable to adequately show clients that we are continuing to obtain additional patent assets that are being or may be asserted against them, clients may choose not to renew their subscriptions once they have vested into a perpetual license in all patent assets they believe are materially relevant to their businesses.

30

Our subscription agreements generally provide our clients with a right to terminate their membership if we fail to meet certain conditions. If we fail to meet those conditions and clients elect to terminate their subscription agreements, our operating results will be harmed.

Until recently, our form of subscription agreement provided that we will use commercially reasonable efforts to spend at least a specified minimum amount each year to acquire patent assets related broadly to information technology. If we fail to meet this standard, the clients whose agreements contain this standard have the right to terminate their memberships. In addition, a select number of our subscription agreements also provide that if we fail in any year to acquire patent assets broadly related to information technology worth at least a specified amount that is lower than the minimum amount generally included in our subscription agreements, then those clients have the right to terminate their memberships. If we fail to meet these standards and clients elect to terminate their membership, our operating results will be harmed.

Because we generally recognize revenue from membership subscriptions over the term of the membership, upturns or downturns in membership sales may not be immediately reflected in our operating results. As a result, our future operating results may be difficult to predict.

We generally recognize subscription fees received from clients ratably over the period of time to which those fees apply. Most of our clients are invoiced annually, and thus their fees are recognized as revenue over the course of 12 months. Consequently, a decline in new or renewed subscriptions in any one quarter will not be fully reflected in that quarter’s revenue and will negatively affect our revenue in future quarters. In addition, we may be unable to adjust our cost structure quickly to reflect this reduced revenue. Accordingly, the effect of either significant downturns in membership sales or rapid market acceptance of our solution may not be fully reflected in our results of operations in the period in which such events occur. Our membership subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as subscription fees from new clients must generally be recognized over the applicable membership term.

Our subscription fees from clients may decrease due to factors outside of our control. Any reduction in subscription fees could harm our business and operating results.

Each client’s subscription fee is reset yearly based on its reported revenue and operating income measured as of the end of its last fiscal year. If a client who is not already paying the minimum due under our fee schedule experiences reduced operating results, its subscription fee for the next year will decline. As a result, our revenue stream is affected by conditions outside of our control that impact the operating results of our clients.

Our fee schedule is capped for each of our clients. As a result, if one of our clients acquires another client, our future revenue would be reduced as a result of our fee schedule being applied to the combined entity rather than to each entity separately. Any reduction in subscription fees could harm our business and operating results.

New legislation, regulations or court rulings related to enforcing patents could reduce the value of our solution to clients or potential clients and harm our business and operating results.

If Congress, the United States Patent and Trademark Office or courts implement new legislation, regulations or rulings that impact the patent enforcement process or the rights of patent holders, these changes could negatively affect the operating results and business model for NPEs. This, in turn, could reduce the value of our solution to our current and potential clients. For example, limitations on the ability to bring patent enforcement claims, limitations on potential liability for patent infringement, lower evidentiary standards for invalidating patents, increased difficulty for parties making patent assertions to obtain injunctions, reductions in the cost to resolve patent disputes and other similar developments could negatively affect an NPE’s ability to assert its patent rights successfully, decrease the revenue associated with asserting or licensing an NPE’s patent rights and increase the cost of bringing patent enforcement actions. As a result, assertions and the threat of assertions by NPEs may decrease. If this occurs, companies may seek to resolve patent claims on an individual basis and be less willing to subscribe to our solution or renew their memberships. Furthermore, even if companies are interested in subscribing to our solution or maintaining their memberships, companies may be unwilling to pay the subscription fees that we propose. Any of these events could result in a material adverse effect to our business and operating results.

31

If we are unable either to identify patent assets that are being asserted or that could be asserted against existing and potential clients or to obtain such assets at prices that are economically supportable within our business model, we may not be able to attract or retain sufficient clients and our operating results would be harmed.

Our ability to attract new clients and renew the subscription agreements of existing clients depends on our ability to identify patent assets that are being asserted or that could be asserted against our existing or potential clients. There is no guarantee that we will be able to adequately identify those types of patent assets on an ongoing basis and, even if identified, that we will be able to acquire rights to those patent assets on terms that are favorable to us, or at all. As new technological advances occur, some or all of the patent assets we have acquired may become less valuable or obsolete before we have had the opportunity to obtain significant value from those assets.

Our approach to acquiring patent assets generally involves acquiring ownership or a license at a fixed price. Other companies, such as NPEs, often offer contingent payments to sellers of patents that may provide the seller the opportunity to receive greater amounts in the future for the sale of its patents as compared to the fixed price we generally pay. As a result, we may not be able to compete effectively for the acquisition of certain patent assets.

If clients do not perceive that the patent assets we acquire are relevant to their businesses, we will have difficulty attracting new clients and renewing existing clients, and our operating results will be harmed. Similarly, if clients are not satisfied with the amount we deploy to acquire patent assets, they may choose not to renew their subscriptions.

We may not be able to compete effectively against others to attract new clients or acquire patent assets. Any failure to compete effectively could harm our business and results of operations.

In our efforts to attract new clients and retain existing clients, we compete primarily against established patent risk management strategies employed by those companies. Companies can choose from a variety of other strategies to attempt to manage their patent risk, including internal buying or licensing programs, cross-licensing arrangements, patent-buying consortiums or other patent-buying pools and engaging legal counsel to defend against patent assertions. As a result, we spend considerable resources educating our existing and prospective clients on the potential benefits of our solution and the value and cost savings it may provide.

In addition to competing for new clients, we also compete to acquire patent assets. Our primary competitors in the market for patent assets include other entities that seek to accumulate patent assets, including NPEs such as Acacia Research, Altitude Capital Partners, Coller IP, Intellectual Ventures, Millennium Partners and Rembrandt IP Management, along with patent-buying consortiums such as Allied Security Trust. Many of our current or potential competitors have longer operating histories, greater name recognition and significantly greater financial resources than we have. In addition, many NPEs that compete with us to acquire patent assets have complicated corporate structures that include a large number of subsidiaries, so it is difficult for us to know who the ultimate parent entity is and how much capital the related entities have available to acquire patent assets. We also face competition for patent assets from operating companies, including operating companies that are current or prospective clients, that seek to acquire patent assets in connection with new or existing product and service offerings.

We expect to face more direct competition in the future from other established and emerging companies. In addition, as a relatively new company in the patent risk management market, we have limited insight into trends that may develop and affect our business. As a result, we may make errors in predicting and reacting to relevant business trends, making us unable to compete effectively against others.

Our current or potential competitors vary widely in size and in the scope and breadth of the products and services they offer. Many of our competitors have greater financial resources and a larger customer base and sales and marketing teams. The competition we face now and in the future could result in increased pricing pressure, reduced margins, increased sales and marketing expenses and a failure to increase, or the loss of, market share. We may not be able to maintain or improve our competitive position against our current or future competitors, and our failure to do so could seriously harm our business.

Our acquisitions of patent assets are time consuming, complex and costly, which could adversely affect our operating results.

Our acquisitions of patent assets are time consuming, complex and costly to consummate. We utilize many different transaction structures in our acquisitions and the terms of the acquisition agreements tend to be very heavily negotiated. As a result, we incur significant operating expenses during the negotiations even where the acquisition is ultimately not consummated. Even if we successfully acquire particular patent assets, there is no guarantee that we will generate sufficient revenue related to those patent assets to offset the acquisition costs. While we conduct confirmatory due diligence on the patent assets we are considering for acquisition, we may acquire patent assets from a seller who does not have proper title to those assets. In those cases, we may be required to spend significant resources to defend our interest in the patent assets and, if we are not successful, our acquisition may be invalid, in which case we could lose part or all of our investment in the assets.

32

We occasionally identify patent assets that cost more than we are prepared to spend with our own capital resources or that may be relevant only to a very small number of clients. In these circumstances, we may structure a transaction in which certain of our clients contribute funds that are in addition to their subscription fees in order to acquire those patent assets. These structured acquisitions are complex. We may incur significant costs to organize and negotiate a structured acquisition that does not ultimately result in an acquisition of any patent assets. These higher costs could adversely affect our operating results.

Our business model is new and complex, requiring estimates and judgments by our management. Our estimates and judgments are subject to changes that could adversely affect our operating results.

Our patent risk management business model is new and therefore our accounting and tax treatment has limited precedent. The determination of patent asset amortization expense for financial and income tax reporting requires estimates and judgments on the part of management. Some of our patent asset acquisitions are complex, requiring additional estimates and judgments on the part of our management. From time to time, we evaluate our estimates and judgment. However, such estimates and judgment are, by their nature, subject to risks, uncertainties and assumptions, and factors may arise that lead us to change our estimates or judgments. If this or any other changes occur, our operating results may be adversely affected. Furthermore, if the accounting or tax treatment is challenged, we may have to spend considerable time and expense defending our position and we may be unable to successfully defend our accounting or tax treatment, any of which could adversely affect our business and operating results.

We plan to substantially increase our operating expenses to expand our operations, and those increased expenses may negatively impact our profitability.

We expect to significantly increase future expenditures to develop and expand our business, including making substantial expenditures to acquire patent assets and develop new solutions. Our efforts to develop new solutions will result in an increase in our operating expenses with no assurance that such solutions will result in additional revenue that is sufficient to offset the additional expenses we incur.

We also plan to incur additional operating expenses as we hire new personnel, including employees for client relations, patent research and analysis, development of reporting systems and general and administrative functions. From January 1 through June 30, 2011, our headcount grew from 66 to 81 employees. Because we intend to hire aggressively for the remainder of 2011, we expect our operating expenses to increase substantially. In addition, as a public company, we will incur additional significant legal, accounting and other expenses that we did not incur as a private company. If we are not successful in generating additional revenue that is sufficient to offset these expected operating expense increases, our operating results may be harmed.

If we are unable to successfully expand our membership base to include mid-and small-size companies, we may not be able to maintain our growth and our business and results of operations may be harmed.

Many of our current clients are very large companies. The number of companies of that size is limited, so in order for us to continue our growth, we need to expand our membership base to include mid-and small-size companies. There is no guarantee that we will be successful in those efforts. Those companies often have more limited budgets available for solutions of the type we offer compared to larger companies. Those companies may also request solutions that we do not currently offer. They may also have concerns that we will focus our patent acquisition efforts on patent assets that are of more benefit to our larger clients who pay us higher subscription fees. If we are unable to successfully expand our membership base to include more mid- and small-size companies, our growth may slow, and our business may be harmed.

Our revenue is concentrated in a small number of clients, and if we are not able to obtain membership renewals from these clients, our revenue may decrease substantially.

We receive a significant amount of our revenue from a limited number of clients. For example, during the six months ended June 30, 2011, our 10 highest revenue generating clients accounted for approximately 34% of our total revenue. We expect that a significant portion of our revenue will continue to come from a relatively small number of clients for the foreseeable future. If any of these clients choose not to renew their memberships, or if our subscription fees from them decline, our revenue may correspondingly decrease and our operating results may be adversely affected.

33

If we are unable to enhance our current solution or to develop or acquire new solutions to provide additional value to our clients and potential clients, we may not be able to maintain our growth, and our business may be harmed.

In order to attract new clients and retain existing clients, we need to enhance and improve our existing solution and introduce new solutions that meet the needs of our clients. In the future, we may also seek to acquire or invest in businesses, products or technologies that we believe could complement or expand our service offerings, enhance our technical capabilities or otherwise offer growth opportunities. We are currently developing programs to facilitate joint defense and cross-license arrangements among clients that pay us additional fees to participate in those arrangements. As part of our potential joint defense solution, we are developing a plan to establish a risk retention group to help our clients cover costs incurred in defending patent infringement claims. If we facilitate the formation of a risk retention group, we may elect to provide part of the capital necessary to obtain regulatory approval. If we provide part of the risk capital and the risk-retention group experiences losses that exceed projected levels, the value of our investment would be impaired. This impairment could negatively affect our operating results.

The development and implementation of new solutions will continue to require substantial time and resources, as well as require us to operate businesses that would be new to our organization. These or any other new solutions may not be introduced in a timely manner or at all. If we do introduce these or any other solutions, we may be unable to implement such solutions in a cost-effective manner, achieve wide market acceptance, meet client expectations or generate revenue sufficient to recoup the cost of developing such solutions. Any new solutions we introduce may expose us to additional laws, regulations and risks. If we are unable to develop these or other solutions successfully and enhance our existing solution to meet client requirements or expectations, we may not be able to attract or retain clients, and our business may be harmed.

We have experienced rapid growth in recent periods, and we plan to continue to grow our operations to support our current solution and the development of new solutions. If we fail to manage our growth effectively, we may be unable to execute our business plan, maintain high levels of service or address competitive challenges adequately.

We have substantially expanded our overall business, headcount and operations in recent periods. We plan to aggressively expand our operations and headcount in the future in order to support our efforts to increase our membership base, continue to acquire valuable patent assets and develop additional solutions. Further, increases in our membership base could create challenges in our ability to provide our solutions and support our clients. In addition, we will be required to continue to improve our operational, financial and management controls and our reporting procedures. As a result, we may be unable to manage our business effectively in the future, which may negatively impact our operating results.

In some acquisitions of patent assets, we may seek to defer payment or finance a portion of the acquisition price. This approach may put us at a competitive disadvantage and could result in harm to our business.

We have limited capital and often seek to negotiate acquisitions of patent assets where we can defer payments or finance a portion of the acquisition price. These types of debt financing or deferred payment arrangements are generally not as attractive to sellers of patent assets as receiving the full purchase price for those assets in cash at the closing of the acquisition. As a result, we might not compete effectively against other companies in the market for patent assets, many of whom have greater cash resources than we have. In addition, any failure to satisfy our debt repayment obligations may result in adverse consequences.

If we are not perceived as a trusted defensive patent aggregator, our ability to gain wide market acceptance will be harmed, and our operating results could be adversely affected.

Our reputation, which depends on earning and maintaining the trust of existing and potential clients, is critical to our business. Our reputation is vulnerable to many threats that can be difficult or impossible to control and costly or impossible to remediate. For our business to be successful, we must continue to educate potential clients about our role as a trusted intermediary in the patent market. We occasionally sell previously acquired patents to third parties. If a patent we sell to a third party is later asserted against a client who joined our network after the patent was sold and who did not receive a license to the patents in connection with the sale, our reputation could be harmed. If our reputation is harmed, we may have more difficulty attracting new clients and retaining existing clients, and our operating results could be adversely affected.

34

We may become involved in patent litigation proceedings related to our clients. Our involvement could cause us to expend significant resources and could require us to disclose information related to our clients, which could cause such clients not to renew their subscriptions with us.

The patent market is heavily impacted by litigation. As a result, we may be required, by subpoena or otherwise, to participate in patent litigation proceedings related to our clients. Our participation in any such proceedings could require us to expend significant resources and could also be perceived as adverse to the interests of our clients or potential clients if we are required to disclose any information about our clients that we have gathered in the course of their memberships. These additional expenditures and potential disclosures could make it more difficult for us to attract new clients and retain existing clients and our results of operations could be harmed.

Interpretations of current laws and the passage of future laws could harm our business and operating results.

Because of our limited operating history and our presence in an emerging industry, the application to us of existing United States and foreign laws is unclear. Many laws do not contemplate or address the specific issues associated with our patent risk management solution or other products and services we may provide in the future. It is possible that courts or other governmental authorities will interpret existing laws regulating risk management and insurance, competition and antitrust practices, taxation, the practice of law and patent usage and transfers in a manner that is inconsistent with our business practices. Our business, prospects, financial condition and results of operations may be harmed if our operations are found to be in violation of any existing laws or any other governmental regulations that may apply to us. Additionally, existing laws may restrict our ability to deliver services to our clients, limit our ability to grow and cause us to incur significant expenses in order to comply with such laws and regulations. Even if our business practices are ultimately not affected, we may incur significant cost to defend our actions, incur negative publicity and suffer substantial diversion of management time and effort. This could have a material adverse effect on our business, prospects, financial condition and results of operations.

Additionally, we face risks from laws that could be passed in the future. It is impossible to determine the extent of the impact of any new laws, regulations or initiatives that may be proposed, or whether any of the proposals will become law. Compliance with any new or existing laws or regulations could be difficult and expensive, affect the manner in which we conduct our business and negatively impact our business, prospects, financial condition and results of operations.

Any failure to maintain or protect our patent assets or other intellectual property rights could impair our ability to attract or retain clients and maintain our brand and could harm our business and operating results.

Our business is dependent on our ability to acquire patent assets that are valuable to our existing and potential clients. Following the acquisition of patent assets, we spend significant time and resources to maintain the effectiveness of those assets by paying maintenance fees and making filings with the United States Patent and Trademark Office. In some cases, the patent assets we acquire include patent applications which require us to spend resources to prosecute the applications with the United States Patent and Trademark Office. If we fail to maintain or prosecute our patent assets properly, the value of those assets to our clients would be reduced or eliminated, and our business would be harmed.

We might require additional capital to support our business growth and future patent asset acquisitions, and this capital might not be available on acceptable terms, or at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.

We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to acquire patent assets, satisfy debt payment obligations related to patent asset acquisitions, develop new solutions or enhance our existing solution, enhance our operating infrastructure and acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings or enter into credit agreements to secure additional funds. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing secured by us in the future could involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, we may not be able to obtain additional financing on terms favorable to us, or at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.

35

If we fail to develop widespread brand awareness cost-effectively, we may not attract new clients and our business and operating results may suffer.

We believe that developing and maintaining widespread awareness of our brand in a cost-effective manner is critical to achieving widespread acceptance of our solution and is an important element in attracting new clients. Furthermore, we believe that the importance of brand recognition will increase as competition in our market develops. Brand promotion activities may not generate client awareness or yield increased revenue, and even if they do, any increased revenue may not offset the expenses we incurred in building our brand. If we fail to promote and maintain our brand successfully, or if we incur substantial expenses in an unsuccessful attempt to promote and maintain our brand, we may fail to attract or retain clients to the extent necessary to realize a sufficient return on our brand-building efforts.

We are dependent on our management team, and the loss of any key member of this team may prevent us from implementing our business plan, which could harm our future growth and operating results.

Our success depends largely upon the continued services of our executive officers and other key personnel. We do not have employment agreements with any of our executive officers or other key management personnel that require them to remain our employees. Therefore, they could terminate their employment with us at any time without penalty. We do not maintain key person life insurance policies on any of our employees. The loss of one or more of our key employees could seriously harm our business.

Our inability to identify, attract, train, integrate and retain highly qualified employees would harm our business.

Our future success depends on our ability to identify, attract, train, integrate and retain highly qualified technical, sales and marketing, managerial and administrative personnel. In particular, our ability to grow our revenue is dependent on our ability to hire personnel that can identify and acquire valuable patent assets and sign up new clients. Competition for highly skilled sales, business development and technical individuals is intense, and we continue to face difficulty identifying and hiring qualified personnel in some areas of our business. We may not be able to hire and retain such personnel at compensation levels consistent with our existing compensation and salary structure. Many of the companies with which we compete for hiring experienced employees have greater resources than we have. If we fail to identify, attract, train, integrate and retain highly qualified and motivated personnel, our reputation could suffer, and our business, financial condition and results of operations could be adversely affected.

Weak global economic conditions may adversely affect demand for our solution or fees payable under our subscription agreements, which could adversely affect our financial condition and operating results.

Our operations and performance depend significantly on worldwide economic conditions, and the United States and world economies have recently experienced weak economic conditions. Uncertainty about global economic conditions poses a risk as businesses may postpone spending in response to tighter credit, negative financial news and declines in income or asset values. This response could have a material negative effect on the demand for our solution. Furthermore, if our clients experience reduced operating income or revenues as a result of economic conditions or otherwise, it would reduce their subscription fees because those fees are generally reset annually based on the clients’ then-current operating income or revenue. If the subscription fees payable under our subscription agreement are reduced substantially, it would have an adverse effect on our business and results of operations.

We may acquire other companies or technologies, which could divert our management’s attention, result in additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results.

We have in the past and may in the future seek to acquire or invest in businesses, products or technologies that we believe could complement or expand our client offerings, enhance our technical capabilities or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated.

36

We may not be able to integrate the acquired personnel, operations and technologies successfully or effectively manage the combined business following the completion of the acquisition. We may also not achieve the anticipated benefits from the acquired business due to a number of factors, including:

• difficulties in integrating operations, technologies, services and personnel;

• unanticipated costs or liabilities associated with the acquisition;

• incurrence of acquisition-related costs;

• diversion of management’s attention from other business concerns;

• potential loss of key employees;

• additional legal, financial and accounting challenges and complexities in areas such as tax planning, cash management and financial reporting;

• use of resources that are needed in other parts of our business; and

• use of substantial portions of our available cash to consummate the acquisition.

Future acquisitions could also result in dilutive issuances of equity securities or the incurrence of debt, which could adversely affect our operating results. In addition, if an acquired business fails to meet our expectations, our operating results, business and financial condition may suffer.

We have incurred significant increased costs as a result of operating as a public company, and our management will be required to devote substantial time to compliance efforts.

As a public company, we have incurred and will continue to incur significant legal, accounting, investor relations and other expenses that we did not incur as a private company, including costs associated public company reporting requirements. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules subsequently implemented by the SEC and The Nasdaq Stock Market, impose additional requirements on public companies, including enhanced corporate governance practices. For example, the listing requirements for The Nasdaq Stock Market provide that listed companies satisfy, among other things, certain corporate governance requirements relating to independent directors, audit committees, distribution of annual and interim reports, stockholder meetings, stockholder approvals, solicitation of proxies, conflicts of interest, stockholder voting rights and codes of business conduct. Our management and other personnel will need to devote a substantial amount of time to satisfy these requirements. Moreover, these rules and regulations have increased our ongoing legal and financial compliance costs and have made some activities more time consuming and costly.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements could be impaired, which could adversely affect our operating results, our ability to operate our business and investors’ views of us.

Ensuring that we have internal financial and accounting controls and procedures adequate to produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be re-evaluated frequently. We have in the past discovered, and may in the future discover, areas of our internal financial and accounting controls and procedures that need improvement. The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our testing, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses. Our compliance with Section 404 will require that we incur substantial accounting expense and expend significant management time on compliance-related issues. We need to hire additional accounting and financial staff, improve our existing controls and implement new processes. We cannot be certain that our actions to improve our internal controls over financial reporting will be sufficient, or that we will be able to implement our planned processes and procedures in a timely manner. Moreover, if we are not able to comply with the requirements of Section 404 in a timely manner, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, investors could lose confidence in the reliability of our financial statements, which could cause the market price of our common stock to decline. In addition, a delay in compliance with Section 404 could subject us to sanctions or investigations by The Nasdaq Stock Market, the SEC or other regulatory authorities, make us ineligible for short form resale registrations or result in the inability of registered broker-dealers to make a market in our common stock, any of which could further reduce our stock price and could harm our business.

37

Furthermore, implementing any appropriate changes to our internal control over financial reporting may entail substantial costs in order to modify our existing accounting systems, may take a significant period of time to complete and may distract our officers, directors and employees from the operation of our business. These changes, however, may not be effective in maintaining the adequacy of our internal control over financial reporting, and any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. In addition, investors’ perceptions that our internal control over financial reporting is inadequate or that we are unable to produce accurate financial statements may adversely affect our stock price. While neither we nor our independent registered public accounting firm have identified deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, there can be no assurance that material weaknesses will not be subsequently identified.

Changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and may have an effect on our reported results of operations.

A change in accounting standards or practices could have a significant effect on our reported results and may affect our reporting of transactions completed before the change is effective. New accounting pronouncements and varying interpretations of accounting pronouncements have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business.

Our results of operations could vary as a result of the methods, estimates and judgments we use in applying our accounting policies.

The methods, estimates and judgments we use in applying our accounting policies have a significant impact on our results of operations, including the reported amounts of assets, liabilities, revenue and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, patent assets, other investments, income taxes, litigation and other intangibles, and other contingencies. Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties and assumptions, and factors may arise over time that lead us to change our methods, estimates and judgments. In addition, actual results may differ from these estimates under different assumptions or conditions. Changes in those methods, estimates and judgments could significantly affect our results of operations.

Our operations are subject to risks of natural disasters, acts of war, terrorism or widespread illness at our domestic and international locations, any one of which could result in a business stoppage and negatively affect our operating results.

Our business operations depend on our ability to maintain and protect our facility, computer systems and personnel, which are primarily located in the San Francisco Bay Area. The San Francisco Bay Area is in close proximity to known earthquake fault zones. Our facility and transportation for our employees are susceptible to damage from earthquakes and other natural disasters such as fires, floods and similar events. Should earthquakes or other catastrophes, such as fires, floods, power outages, communication failures or similar events disable our facilities, we do not have readily available alternative facilities from which we could conduct our business, which stoppage could have a negative effect on our operating results. Acts of terrorism, widespread illness and war could also have a negative effect at our international and domestic facilities.

Risks Related to Ownership of Our Common Stock

The trading price of our common stock is likely to be volatile, and you might not be able to sell your shares at or above the price at which you purchased them.

There was no public market for our common stock prior to the IPO. The market price of our common stock could be subject to wide fluctuations in response to various factors, some of which are beyond our control. These factors include those discussed in this “Risk Factors” section of this Form 10-Q and others such as:

• variations in our financial condition and operating results;

• adoption or modification of laws, regulations, policies, procedures or programs applicable to our business, including those related to the enforcement of patent claims;

• announcements of technological innovations, new products and services, acquisitions, strategic alliances or significant agreements by us or by our competitors;

• addition or loss of significant clients;

• recruitment or departure of members of our Board of Directors, management team or other key personnel;

• the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

• changes in the estimates of our operating results or changes in recommendations by any securities analysts that elect to follow our common stock;

• market conditions in our industry and the economy as a whole;

• price and volume fluctuations in the overall stock market or resulting from inconsistent trading volume levels of our shares;

• lawsuits threatened or filed against us;

• sales of our common stock by us or our stockholders; and

• the expiration of market standoff or contractual lock-up agreements.

In recent years, the stock market has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the changes in the operating performance of the companies whose stock is experiencing those price and volume fluctuations. Broad market and industry factors may seriously affect the market price of our common stock, regardless of our actual operating performance.

Our three largest stockholders and our directors and executive officers, in the aggregate, own approximately 75% of our outstanding common stock and will be able to exercise substantial control over all matters requiring stockholder approval. This concentration of ownership limits your ability to influence corporate matters.

As of June 30, 2011, affiliates of Index Ventures, affiliates of Charles River Ventures and KPCB Holdings, Inc. each beneficially own approximately 18% of our outstanding common stock, and our directors and executive officers and their affiliates, in the aggregate, beneficially own approximately 75% of our outstanding common stock. As a result, these stockholders will be able to exercise substantial control over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or its assets. This concentration of ownership limits your ability to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring control over us. In addition, each of Index Ventures, Charles River Ventures and KPCB Holdings, Inc. currently have a representative on our Board of Directors.

An active trading market for our common stock may not develop or be sustained.

We have a limited history as a public company. An active trading market may not develop or may not be sustained. The lack of an active market may impair your ability to sell your shares at the time you wish to sell them or at a price that you consider reasonable. The lack of an active market may also reduce the fair market value of your shares. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.

39

If securities analysts do not publish research or publish unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities analysts publish about us or our business. In the event that one or more of the analysts who covers us downgrades our stock or publishes unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

Substantial future sales of shares by existing stockholders, or the perception that such sales may occur, could cause our stock price to decline, even if our business is doing well.

If our existing stockholders, particularly our directors and executive officers and the venture capital funds affiliated with our current and former directors, sell substantial amounts of our common stock in the public market, or are perceived by the public market as intending to sell substantial amounts of our common stock, the trading price of our common stock could decline. Currently, only the shares of common stock sold in the IPO are freely tradable, without restriction, in the public market. Our officers, directors and the holders of substantially all of our common stock have entered into contractual lock-up agreements with the underwriters of the IPO pursuant to which they have agreed not to sell or otherwise transfer any of their common stock or securities convertible into or exchangeable for shares of common stock for a period through the date approximately 180 days after the date of the final prospectus for the IPO. However, the lead underwriters in the IPO may permit these holders to sell shares prior to the expiration of the lock-up agreements with the underwriters.

In addition, MHV Partners LLC, an entity affiliated with Shelby Bonnie, and Sanford Robertson, both of whom purchased shares of our common stock in April 2011, have agreed with us to a one-year restricted period with respect to such shares.

After the contractual lock-up agreements pertaining to the IPO expire, up to an additional 37,426,856 shares will be eligible for sale in the public market, 35,011,972 of which are held by directors, executive officers and other affiliates and will be subject to volume limitations under Rule 144 under the Securities Act. In addition, some of these shares are limited by restrictions on sales related to our right of repurchase on unvested shares.

Some of our existing stockholders have demand and piggyback rights to require us to register with the SEC up to 34,636,994 shares of our common stock, subject to expiration of the contractual lock-up agreements. If we register these shares of common stock, the stockholders would be able to sell those shares freely in the public market.

The 7,755,828 shares that were subject to outstanding options and 84,467 shares of RSUs as of June 30, 2011 will become eligible for sale in the public market to the extent permitted by the provisions of various vesting agreements, the contractual lock-up agreements and Rules 144 and 701 under the Securities Act.

Additionally, on May 4, 2011 we registered 9,214,922 shares of our common stock that we may issue under our equity plans. Such shares can be freely sold in the public market upon issuance, subject to any vesting or contractual lock-up agreements.

If any of these additional shares described are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.

As a newly public company, our stock price may be volatile, and securities class action litigation has often been instituted against companies following periods of volatility of their stock price. Any such litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

In the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

40

Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of our company and may affect the trading price of our common stock.

We are a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change in control would be beneficial to our existing stockholders. In addition, our amended and restated certificate of incorporation and amended and restated bylaws may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. Our amended and restated certificate of incorporation and amended and restated bylaws:

• authorize the issuance of “blank check” preferred stock that could be issued by our Board of Directors to thwart a takeover attempt;

• establish a classified Board of Directors, as a result of which the successors to the directors whose terms have expired will be elected to serve from the time of election and qualification until the third annual meeting following their election;

• require that directors only be removed from office for cause and only upon a majority stockholder vote;

• provide that vacancies on our Board of Directors, including newly created directorships, may be filled only by a majority vote of directors then in office;

• limit who may call special meetings of stockholders;

• prohibit stockholder action by written consent, requiring all actions to be taken at a meeting of the stockholders;

• do not provide stockholders with the ability to cumulate their votes;

• require supermajority stockholder voting to effect certain amendments to our amended and restated certificate of incorporation and amended and restated bylaws; and

• require advance notification of stockholder nominations and proposals.

We do not currently intend to pay dividends on our common stock in the foreseeable future, and consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We have never declared or paid cash dividends on our common stock and do not anticipate paying any cash dividends to holders of our common stock in the foreseeable future. Consequently, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our stockholders have purchased their shares.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

From January 1 to June 30, 2011, we granted awards for an aggregate of 2,250,616 shares of our common stock to our employees, consultants and other service providers. From January 1 to June 30, 2011, we issued and sold an aggregate of 777,425 shares of our common stock to our employees, consultants, and other service providers at prices ranging from $0.25 to $9.85 per share for an aggregate of $623,244 pursuant to exercises of options granted and a stock award. No underwriters were involved in the foregoing sales of securities. These issuances were undertaken in reliance upon the exemption from registration requirements of Rule 701 and Section 4(2) of the Securities Act. All securities described in this paragraph are deemed restricted securities for purposes of the Securities Act. The instruments representing such issued securities included appropriate legends setting forth that the securities had not been registered and the applicable restrictions on transfer.

Use of Proceeds

The IPO was effected through a Registration Statement on Form S-1 (File No. 333-171817) that was declared effective by the SEC on May 3, 2011, which registered an aggregate of 9,695,000 shares of our common stock, including 1,264,565 shares that the underwriters had the option to purchase. On May 9, 2011, 9,065,000 shares of common stock were sold on our behalf and 630,000 shares of common stock were sold on behalf of the selling stockholders, at an initial public offering price of $19.00 per share, for an aggregate gross offering price of $172,235,000 to us, and $11,970,000 to the selling stockholders. The underwriters of the offering were Goldman Sachs & Co., Barclays Capital, Allen & Company LLC, Robert W. Baird & Co., Incorporated and Cowen and Company, LLC. Following the sale of the shares in connection with the closing of the IPO, the offering terminated.

As a result of the offering, the Company received net proceeds of approximately $160.2 million, net of underwriting discounts and commissions. The Company incurred offering costs of $2.9 million. The net offering proceeds have been invested in short-term investment-grade securities and money market funds.

There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b).

Litigation

From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with its legal counsel, the need to record a liability for litigation. A liability is recorded when and if it is determined that such a liability for litigation is both probable and reasonably estimable. As of June 30, 2011, the Company was not a party to any litigation and no liabilities for litigation have been accrued.

Other Commitments and Contingencies

On September 10, 2010, the Company entered into certain agreements with a special-purpose entity formed for the sole purpose of acquiring specific patent assets that had been made available for sale by a third party. If the entity was successful in acquiring the patent assets, the Company had agreed to make a $5.0 million investment in the equity securities of the entity and serve as the exclusive licensing agent for the entity. As of June 30, 2011, the third party had completed the sale of the assets and the special-purpose entity was not the buyer. Therefore, no investment in such entity has been made and the Company has no further obligations under these agreements.

On December 12, 2008, in connection with the acquisition of certain patent assets from an unaffiliated third party in an arm's-length transaction, the Company agreed to make a one-time payment of $5.0 million in the event that the Company earns $170.0 million of annual subscription revenues in any calendar year. No provision has been made for this contingency as of June 30, 2011.

Net Income Attributable To Common Stockholders

3. Net Income Attributable to Common Stockholders

Basic and diluted net income per share attributable to common stockholders are presented in conformity with the two-class method required for participating securities. Holders of shares of Series A, Series A-1, Series B and Series C redeemable convertible preferred stock are each entitled to receive 8% per annum non-cumulative dividends, payable prior and in preference to any dividends on common stock. In addition, the holders of restricted common stock are entitled to receive non-forfeitable dividends if declared.

Under the two-class method, basic net income per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period non-cumulative dividends attributable to shares of Series A, Series A-1, Series B and Series C redeemable convertible preferred stock, among common stockholders, restricted stockholders and Series A, Series A-1, Series B and Series C redeemable convertible preferred stockholders. Diluted net income per share attributable to common stockholders is computed by using the weighted average number of shares of common stock outstanding, including potential dilutive shares of common stock, assuming the dilutive effect of outstanding stock options and unvested restricted stock units using the treasury stock method.

The following table presents the calculation of basic and diluted net income per share attributable to common stockholders (in thousands, except per share data):

On February 23, 2011, the Board of Directors adopted the 2011 Equity Incentive Plan (the "2011 Plan"), which became effective in May 3, 2011, the date of the Company's IPO. The 2011 Plan provides for the issuance of incentive stock options, non-qualified stock options, stock appreciation rights, restricted shares of the Company's common stock, and stock units to employees, directors and consultants. The Board of Directors reserved 1,500,000 shares of common stock for future issuance under the 2011 Plan.

On August 11, 2008, the Board of Directors adopted the 2008 Stock Option Plan (the "2008 Plan"), which provides for the issuance of incentive stock options, non-qualified stock options, as well as the direct award or sale of shares of common stock to employees, directors and consultants for up to 9,019,474 shares of common stock, as amended. No further awards will be made under the 2008 Plan; however, all awards outstanding under the 2008 Plan will continue to be governed by the existing terms.

Under both the 2008 Plan and 2011 Plan, incentive stock options and non-qualified stock options are to be granted at a price not less than 100% of the fair value of the stock at the date of grant. Options granted to newly hired employees vest 25% on the first anniversary of the date of hire and ratably each month over the ensuing 36-month period. Options granted to existing employees generally vest ratably over the 48 months following the date of grant. Options are exercisable for a maximum period of ten years after date of grant. Incentive stock options granted to stockholders who own more than 10% of the outstanding stock of the Company at the time of grant must be issued at an exercise price not to be less than 110% of the fair value of the stock on the date of grant.

As of June 30, 2011 there were 1,469,234 shares available for grant under the 2011 Plan.

Stock Options

The total stock options outstanding are summarized as follows:

	Number of Options			Weighted- Average Exercise Price

Stock-Based Compensation Related to Employees and Non-Employee Directors

The Company estimates the fair value of stock options using the Black-Scholes option pricing model. Option valuation models, including the Black-Scholes option pricing model, require the input of various assumptions, including stock price volatility. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. The weighted average assumptions and resulting fair values were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2011			2010			2011			2010
Risk-free interest rate		2.38	%		2.57	%		2.58	%		2.69	%
Expected volatility		58	%		60	%		58	%		60	%
Expected dividend yield		—			—			—			—
Expected term (years)		5.9			6.0			6.5			6.0
Weighted average estimated fair value	$	11.26		$	1.43		$	7.41		$	1.32

For Restricted Stock Units (RSUs), stock-based compensation expense was calculated based on the Company's stock price on the date of grant, multiplied by the number of units granted. The grant date fair value of RSUs, less estimated forfeitures, is recognized on a straight-line basis over the requisite service period.

Stock-based compensation expense related to employees was $1.3 million and $2.1 million, for the three and six months ended June 30, 2011, respectively. Stock compensation expense related to employees was $146,000 and $283,000, for the three and six months ended June 30, 2010, respectively. Stock-based compensation of $17,000 and $29,000 was capitalized during the three and six months ended June 30, 2011, respectively, as part of the cost of internal-use software. No stock-based compensation expense was capitalized during the three or six months ended June 30, 2010.

Stock-based compensation expense is recognized ratably over the requisite service period. At June 30, 2011, there was $18.6 million of unrecognized compensation cost related to options which is expected to be recognized over a weighted average period of 3.9 years. At June 30, 2011, there was $1.8 million of unrecognized compensation cost related to RSUs which is expected to be recognized over a weighted average period of 3.8 years. Future option grants will increase the amount of stock-based compensation expense to be recorded.

Stock-Based Compensation Related to Non-Employees

The Company periodically grants options to non-employees in exchange for goods and services. During the six months ended June 30, 2011, the Company issued 10,000 shares of common stock and options to purchase 35,000 shares of common stock to non-employees in exchange for services. No awards were granted to non-employees in exchange for goods and services during the six months ended June 30, 2010.

Stock-based compensation expense related to non-employees was $0.6 million and $0.8 million for the three and six months ended June 30, 2011, respectively. Stock-based compensation expense related to non-employees was $46,000 and $66,000 for the three and six months ended June 30, 2010, respectively. The Company accounts for these stock options using the variable accounting model and re-measures them each accounting period.

Basis Of Presentation And Significant Accounting Policies

1. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying interim consolidated financial statements of RPX Corporation (also referred to herein as "RPX" or the "Company") are unaudited and have been prepared in accordance with the accounting principles generally accepted in the United States of America ("US GAAP") and with the instructions for Form 10-Q and Regulation S-X statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company's prospectus filed with the Securities and Exchange Commission ("SEC") on May 4, 2011. The unaudited consolidated financial statements include the accounts of RPX and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The accompanying interim consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the Company's financial position and results of operations for the periods presented. The consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

There have been no significant new accounting pronouncements or changes to the critical accounting policies disclosed in the Company's prospectus that have had a significant impact on its consolidated financial statements or notes thereto.

Liquidity and Capital Resources

In May 2011, the Company completed its initial public offering ("IPO") of its common stock in which the Company issued 9,065,000 common shares and received cash proceeds of $160.2 million, net of underwriting discounts and commissions. The Company incurred offering costs of $2.9 million. Prior to the IPO, substantially all of the Company's operations and patent asset acquisitions had been financed through the private sale of equity securities, subscription fees collected from its clients and patent-seller financing.

As of June 30, 2011 and December 31, 2010, the Company had cash and cash equivalents of $159.4 million and $46.7 million, respectively, and retained earnings of $25.0 million and $10.7 million, respectively. Management expects that it will use substantial cash in the future to acquire additional patent assets and service the obligations undertaken in connection with prior patent asset purchases. Management believes that the Company has adequate cash resources to continue its operations for the foreseeable future.

Concentration of Risk

The Company is subject to concentrations of credit risk principally attributable to cash and cash equivalents, investments and accounts receivable. The Company places its cash in non-interest bearing accounts at financial institutions which are insured by the Federal Deposit Insurance Corporation. Cash equivalents primarily consist of institutional money market funds and short-term investments consist of U.S. Government and Agency securities.

Credit risk with respect to accounts receivable is generally mitigated by short collection periods and/or subscription agreements that provide for payments in advance of the rendering of services. Two clients accounted for 53% and 37% of accounts receivable at June 30, 2011. Three clients accounted for 45%, 33% and 22% of accounts receivable at December 31, 2010.

No client accounted for 10% or more of subscription fee revenue for the three or six months ended June 30, 2011 and 2010.

Short-Term Investments

The Company holds short-term investments in marketable debt securities, consisting primarily of fixed income U.S. Government and Agency securities. The Company classifies these securities as "available-for-sale", and carries them at fair value on the consolidated balance sheets. Any unrealized gains or losses are recorded, net of estimated taxes, in accumulated other comprehensive income, a component of stockholders' equity. Realized gains and losses are recognized upon sale. The specific identification method is used to determine the cost basis of fixed income securities sold.

The Company considers its investments as available to support current operations. Consequently, the Company may not hold securities with maturities greater than twelve months until maturity. As a result, the Company classifies its investments including those with stated maturities beyond twelve months, as current assets in the accompanying consolidated balance sheets.

The Company periodically evaluates its investments for impairment due to declines in market value considered to be "other-than-temporary". This evaluation consists of several qualitative and quantitative factors, including the Company's ability and intent to hold the investment until a forecasted recovery occurs, as well as any decline in the investment quality of the security and the severity and duration of the unrealized loss. In the event of a determination that a decline in market value is other-than-temporary, the Company will recognize an impairment loss, and a new cost basis in the investment will be established. To date, the Company has not recorded any impairment related to its investments in its consolidated statement of operations.

Restricted Cash

The Company had restricted cash of $720,000 at both June 30, 2011 and December 31, 2010 pledged under two lines of credit. See Note 11.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company evaluates goodwill for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. Because the Company has one reporting unit, the Company utilizes the entity-wide approach to assess goodwill for impairment. No impairment has been recorded through June 30, 2011.

Intangible Assets, Net

Intangible assets, net consist of intangible assets acquired from other companies as a result of acquisitions. Such assets are capitalized and amortized on a straight-line basis over the estimated useful life of the intangible assets. Intangible assets, net excludes patent related intangible assets, which are recorded within patent assets, net in the accompanying consolidated balance sheets.

Internal-Use Software and Website Development Costs

For its website development costs and the development costs related to other internal-use software, the Company capitalizes costs incurred during the application development stage, and reflects such amounts within the property and equipment, net line item on the consolidated balance sheets. Costs related to preliminary project activities, minor enhancement and maintenance and post implementation activities are expensed as incurred. Internal-use software is generally amortized on a straight-line basis over three years beginning on the date the software is placed into service. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.

For the three and six months ended June 30, 2011, the Company capitalized $0.4 million and $0.6 million of software development costs, respectively. No amount was capitalized for either the three or six months ended June 30, 2010. Amortization of internal-use software was $23,000 for both the three and six months ended June 30, 2011. There was no amortization of internal-use software for either the three or six months ended June 30, 2010.

Comprehensive Income

Comprehensive income consists of net income and charges or credits to stockholders' equity primarily related to changes in unrealized gains or losses on marketable securities, net of taxes. For the periods presented, the Company's comprehensive net income approximates its net income, therefore no separate components of comprehensive income are provided.

Recent Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2011-05, "Presentation of Comprehensive Income" ("ASU 2011-05"). ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of shareholders' equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 is effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early adoption is permitted. The adoption of this guidance is not expected to have material impact on the Company's consolidated financial position, results of operations, or cash flows.

In May 2011, the FASB issued ASU 2011-04, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS" ("ASU 2011-04"). The amendments in ASU 2011-04 result in common fair value measurement and disclosure requirements in U.S. GAAP and IFRS. Consequently, ASU 2011-04 changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. For many of the requirements, the FASB does not intend for the amendments in ASU 2011-04 to result in a change in the application of the requirements in Topic 820. ASU 2011-04 is effective prospectively for interim and annual reporting periods beginning after December 15, 2011. The adoption of this guidance is not expected to have material impact on the Company's consolidated financial position, results of operations, or cash flows.

In December 2010, the FASB issued ASU 2010-29, "Disclosure of Supplementary Pro Forma Information for Business Combinations" ("ASU 2010-29"). ASU 2010-29 amends and clarifies the acquisition date to be used for reporting pro forma financial disclosures when comparative financial statements are presented. In addition, it requires a description of the nature of and amount of any material, non-recurring pro forma adjustments directly attributable to the business combination. ASU 2010-29 is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The Company adopted this amendment effective January 1, 2011. There was no impact on the Company's consolidated financial position, results of operations, or cash flows.

In December 2010, the FASB issued ASU 2010-28, "When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts" ("ASU 2010-28"). ASU 2010-28 modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance which requires that goodwill of a reporting unit be tested for impairment 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 amount. This ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2010. The Company adopted this amendment effective January 1, 2011. There was no impact on the Company's consolidated financial position, results of operations, or cash flows.

The Company's financial assets are valued using market prices on both active markets ("Level 1") and less active markets ("Level 2"). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments. As of June 30, 2011 and December 31, 2010, the Company did not have any financial assets without observable market values that would require a high level of judgment to determine fair value ("Level 3").

Changes in the carrying value of patent assets during the periods ended were as follows (in thousands):

	June 30, 2011			December 31, 2010
Balance, beginning of period	$	126,508		$	82,759
Acquisition costs of patent assets		41,151			88,639

Other adjustments		—			(2,003	)
Balance, end of period	$	139,844		$	126,508

The Company's acquired patent assets are comprised of intellectual property rights that relate to information technologies used by companies in a variety of industries, including software, e-commerce, semiconductors, financial services, mobile communications, consumer electronics and networking.

The Company amortizes each acquired portfolio of patent assets on a straight-line basis over its estimated economic useful life. As of June 30, 2011 and December 31, 2010, the estimated economic useful lives of the Company's patent assets generally ranged from 24 to 60 months, and the weighted average estimated economic useful life was 49 months for both periods.

The following table summarizes the estimated future amortization expense of patent assets as of June 30, 2011 (in thousands):

Year Ending December 31,
2011 (remainder)	$	30,926
2012		49,298
2013		35,484
2014		16,071
2015		6,999
Thereafter		1,066
Total estimated future amortization expense	$	139,844

Amortization expense was approximately $14.3 million and $27.8 million for the three and six months ending June 30, 2011, respectively. Amortization expense was approximately $7.5 million and $10.0 million for the three and six months ending June 30, 2010, respectively.

Structured Acquisitions

Structured acquisitions are transactions involving patent assets that cost more than the Company is prepared to spend with its own capital resources or that are relevant only to a very small number of clients. In such transactions, the Company works to acquire these assets with financial assistance from the particular clients against whom the assets are being or may be asserted. When this occurs, the participating clients typically pay amounts separate from their subscription fees and receive an immediate perpetual license to the acquired patent assets. The Company may treat the payments received from the participating clients as revenue either on a gross or a net basis depending on the specific facts and circumstances of the transaction. In the event that such payments are recognized on a net basis, the Company will capitalize the acquired asset that relates to its non-participating clients. In such instance, the cost basis of the acquired patent rights excludes the amounts paid by the participating client.

Barter Transactions

The Company accounts for non-monetary exchanges in accordance with ASC 845, Non-monetary Transactions ("ASC 845"), which requires non-monetary exchanges to be based on the fair value of the assets or services involved. There were no barter transactions during the three months ended June 30, 2011. During the six months ended June 30, 2011, the total fair value of intangible assets exchanged for subscription services was approximately $120,000. No gain or loss was recorded as a result of this exchange. There were no barter transactions during the three or six months ended June 30, 2010.

Operating segments are components of an enterprise about which separate financial information is available. Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is its chief executive officer. The Company's chief executive officer reviews financial information presented on a consolidated basis and, as a result, the Company concluded that there is only one operating and reportable segment.

The Company markets its solution to companies around the world. Revenue is generally attributed to geographic areas based on the country in which the customer is domiciled.

On June 1, 2011, RPX acquired substantially all of the assets of a patent research and intellectual property news provider for $3.0 million in cash. The acquired business is a patent research and intellectual property news provider. The acquisition expands RPX's market intelligence and data analysis capabilities. The acquisition has been accounted for as a business combination. Identifiable intangible assets acquired were recorded at fair value as of the acquisition date. No cash or tangible assets were acquired and no liabilities assumed. Acquisition-related costs of $43,000 were expensed during the three months ended June 30, 2011.

Under business combination accounting, the total purchase price was allocated to the acquired company's identifiable intangible assets based on their estimated fair values as of June 1, 2011 with remainder recorded as goodwill. Approximately $1.7 million of goodwill and $1.3 million of identifiable intangible assets were allocated in connection with the acquisition. The goodwill primarily relates to cost benefits and operational synergies realized by applying the research capabilities inherent in the acquired company's business to other data and research systems at RPX. The acquired goodwill of $1.7 million is deductible for U.S. federal income tax purposes.

RPX included the effect of the transaction in its results of operations prospectively from the date of the acquisition. Pro forma financial information for the acquisition has not been presented, as the effects were not material to RPX's historical consolidated financial statements.

On August 5, 2010, the Company entered into a standby letter of credit agreement with a banking institution. The credit facility provides for a $220,000 line of credit in conjunction with the Company's corporate real estate lease. The credit facility, which expires on June 14, 2013, is secured by a priority interest in the Company's savings account at the banking institution in the amount of $220,000. This amount has been classified as non-current restricted cash in the consolidated balance sheets.

On September 23, 2008, the Company entered into a line of credit agreement with a banking institution. The credit facility provides for a $500,000 line of credit. The credit is secured by a priority interest in the Company's savings account at the banking institution in the amount of $500,000, which has been classified as current restricted cash in the consolidated balance sheets. Under the credit facility, a sub-facility of $300,000 is available for a company-sponsored travel and expense credit card program, and a sub-facility of $200,000 is available under a revolving line of credit. Amounts borrowed under the $300,000 sub-facility, which terminates on April 5, 2012, will be charged a fixed rate of interest of 5% per year. Amounts borrowed under the $200,000 revolving line of credit, which terminates on April 15, 2012, will be charged a variable rate of interest equal to the greater of the banking institution's prime rate or 5%. The banking institution's prime rate at both June 30, 2011 and December 31, 2010 was 3.25%. As of June 30, 2011 and December 31, 2010, balances under the corporate credit card were $169,000 and $108,000, respectively, and such amounts were recorded in accounts payable.

The Company uses an estimated annual effective tax rate based upon a projection of its annual fiscal year results to measure the income tax benefit or expense recognized in each interim period. Our effective tax rate for the six months ended June 30, 2011 was 42.8% compared to 41.9% for the six months ended June 30, 2010. The higher effective tax rate for the six months ended June 30, 2011 was primarily due to an increase in stock-based compensation. The difference between the consolidated effective income tax rate and the U.S. federal statutory rate is primarily attributable to the effect of certain permanent differences and state income taxes.

Tax years 2009 and 2008 are currently under examination by the United States Internal Revenue Service and the State of California Franchise Tax Board. The Company does not expect a material impact on its consolidated financial statements as a result of these examinations.
