RPX Corporation (also referred to herein as “RPX” or the “Company”) helps companies reduce patent-related risk and expense by providing 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. The core of the Company’s solution is defensive patent aggregation, in which it acquires patents or licenses to patents that are being or may be asserted against the Company’s current or prospective clients. The Company may occasionally enter into agreements to acquire covenants not to sue in order to further mitigate its clients’ litigation risk. The acquired patents, licenses to patents and agreements for covenants not to sue are collectively referred to as “patent assets.” The Company’s clients pay an annual subscription fee and in return, receive a license from the Company to substantially all of its patent assets and access to its proprietary patent market intelligence and data. In addition to the Company’s core solution, in August 2012, the Company began underwriting patent infringement liability insurance policies to insure against certain costs of litigation from non-practicing entities (“NPEs”). As of and for the three and nine months ended September 30, 2013, the effect of the insurance policies that have been issued was not material to the Company’s results of operations or financial condition. |

The accompanying condensed consolidated balance sheet as of September 30, 2013, the condensed consolidated statements of operations and the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2013 and 2012, and the condensed consolidated statements of cash flows for the nine months ended September 30, 2013 and 2012, are unaudited. The condensed consolidated balance sheet as of December 31, 2012 was derived from the audited consolidated financial statements which are included in the Company’s Form 10-K for the fiscal year ended December 31, 2012, which was filed with the Securities and Exchange Commission (“SEC”) on March 11, 2013. The unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. | |
The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America and with the instructions for Form 10-Q and Regulation S-X for interim financial statements. Accordingly, they do not include all of the information and notes required for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring items, necessary to state fairly the results of the interim periods have been included in the accompanying financial statements. Operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for any subsequent interim period or for the year ending December 31, 2013. | |
Recently Adopted Accounting Standards | |
In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts of Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”), which amends Comprehensive Income (Topic 220) in the Accounting Standards Codification (“ASC”). These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendments in ASU 2013-02 are effective for the Company’s interim and annual fiscal periods beginning January 1, 2013. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements. | |
In October 2012, the FASB issued ASU 2012-04, Technical Corrections and Improvements (“ASU 2012-04”), which amends a wide range of topics in the ASC. These amendments include technical corrections and improvements to the ASC and conforming amendments related to fair value measurements. The amendments in ASU 2012-04 are effective for the Company’s interim and annual fiscal periods beginning January 1, 2013. The adoption of ASU 2012-04 did not have a material impact on the Company’s consolidated financial statements. | |
In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”), which amends ASU 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment and permits an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles - Goodwill and Other - General Intangibles Other than Goodwill. The amendments in ASU 2012-02 are effective for the Company’s interim and annual fiscal periods beginning January 1, 2013. The adoption of ASU 2012-02 did not have a material impact on the Company’s consolidated financial statements. As of September 30, 2013, the date of the Company’s 2013 annual assessment, the Company’s implied fair value was substantially in excess of its net book value, including goodwill. As such, the Company did not recognize an impairment charge during the three months ended September 30, 2013. |

Basic and diluted net income per share available to common stockholders are presented in conformity with the two-class method required for participating securities. 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 available to common stockholders is computed by dividing the net income available to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Net income available to common stockholders is determined by allocating undistributed earnings between common and restricted common stockholders. Diluted net income per share available 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 restricted stock units using the treasury stock method. | ||||||||||||||||

Commitments and Contingencies | ||
Operating Lease Commitments | ||
The Company generally does not enter into long-term minimum purchase commitments. Its principal long-term commitments consist of obligations under operating leases for office space. There were no substantial changes to its contractual obligations or commitments during the nine months ended September 30, 2013 as presented under the heading “Commitments and Contingencies” in Note 14 of the Notes to Consolidated Financial Statements in Part II, Item 8. “Consolidated Financial Statements and Supplementary Data” included in the Annual Report on Form 10-K for its fiscal year ended December 31, 2012. | ||

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 or legal contingencies. A liability is recorded when and if it is determined that such a liability for litigation or contingencies is both probable and reasonably estimable. No liability for litigation or legal contingencies was recorded as of September 30, 2013 or December 31, 2012. | ||
In June 2013, Kevin O’Halloran, as Trustee of the Liquidating Trust of Teltronics, Inc. (the “Debtor”), filed a complaint in the U.S. Bankruptcy Court for the Middle District of Florida against the Company and Harris Corporation (the “Defendants”). The complaint alleges that the Defendants are liable under federal and state bankruptcy law regarding fraudulent transfers for the value of a patent portfolio purchased by the Company from Harris Corporation pursuant to an agreement entered into in January 2009, and within four years of the date the Debtor filed its petition in bankruptcy. The Company is not currently able to determine whether there is a reasonable possibility that a loss has been incurred, nor can it estimate the potential loss or range of the potential loss that may result from this litigation. | ||
In February 2013, Volkswagen Group of America, Inc. (“Volkswagen”) filed a third-party complaint against the Company as part of an existing patent infringement lawsuit in the U.S. District Court for the Eastern District of Texas that was originally filed by Norman IP Holdings, LLC (“Norman”) and in which Volkswagen is a defendant. The complaint relates to a patent license and acquisition transaction that the Company entered into with Norman and Saxon Innovations, LLC (“Saxon”) in January 2010. The claims allege that the Company, together with Norman and Saxon, violated federal antitrust law and Texas antitrust law. Volkswagen seeks declaratory relief, unspecified monetary damages, and injunctive relief. The Company is not currently able to determine whether there is a reasonable possibility that a loss has been incurred, nor can it estimate the range of the potential loss that may result from this litigation. | ||
In March 2012, Cascades Computer Innovations LLC filed a complaint in U.S. District Court for the Northern District of California (the “Court”) against the Company and five of its clients (collectively the “Defendants”). The complaint alleges that the Defendants violated federal antitrust law, California antitrust law and California unfair competition law. The complaint further alleges that after the Company terminated its negotiations with the plaintiff to license certain patents held by the plaintiff, the Defendants violated the law by jointly refusing to negotiate or accept licenses under the plaintiff’s patents. The plaintiff seeks unspecified monetary damages and injunctive relief. In January 2013, the Court dismissed the complaint against the Defendants and granted the plaintiff leave to amend its complaint. In February 2013, the plaintiff filed an amended lawsuit alleging that the Defendants violated federal antitrust law, California antitrust law and California unfair competition law. The Company is not currently able to determine whether there is a reasonable possibility that a loss has been incurred, nor can it estimate the potential loss or range of the potential loss that may result from this litigation. | ||
Guarantees and Indemnifications | ||
The Company has, in connection with the sale of patent assets, agreed to indemnify and hold harmless the buyer of such patent assets for losses resulting from breaches of representations and warranties made by the Company. The terms of these indemnification agreements are generally perpetual. The maximum amount of potential future indemnification is unlimited. To date, the Company has not paid any amount to settle claims or defend lawsuits. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements since these obligations are not capped but are conditional to the unique facts and circumstances involved. Accordingly, the Company had no liabilities recorded for these agreements as of September 30, 2013 or December 31, 2012. The Company has no reason to believe that there is any material liability related to such indemnification provisions. The Company does not indemnify its clients for patent infringement. | ||
In accordance with its amended and restated bylaws, the Company also indemnifies certain officers and employees for losses incurred in connection with actions, suits or proceedings threatened or brought against such officer or employee arising from his or her service to the Company as an officer or employee, subject to certain limitations. The term of the indemnification period is indefinite. The maximum amount of potential future indemnification is unspecified. The Company has no reason to believe that there is any material liability for actions, events or occurrences that have occurred to date. | ||
Reserves for Known and Incurred But Not Reported Claims | ||
In August 2012, the Company began offering insurance to cover certain costs of litigation brought against its insured clients by NPEs. As of September 30, 2013, the Company has a total of 23 active policies and has recorded a reserve for known and incurred but not reported claims that represent estimated claim costs and related expenses. Such estimates are based on individual case estimates for the reserve for known and incurred but not reported claims and estimates of incurred but not reported losses. The financial statement impact of the reserve for known and incurred but not reported claims was not material to the Company’s results of operations for the three and nine months ended September 30, 2013 or financial condition as of September 30, 2013. | ||
The Company regularly reviews loss reserves using a variety of actuarial techniques and updates them as its loss experience develops. Any changes in estimates are reflected in the Company’s operating results for the period in which the estimates are changed. | ||
Patent Asset Purchase Commitments | ||
During the three months ended September 30, 2013, the Company entered into various agreements to acquire patent assets for an aggregate purchase price of $7.1 million. Pursuant to these agreements, the Company paid the applicable purchase price and acquired the patent assets in October 2013. |

Stock-Based Compensation Related to Employees and Non-Employee Directors | ||||||||||||||||
Stock-based compensation expense for employees and non-employee directors is based on the fair value of the award on the date of grant and is recognized on a straight-line basis over the requisite service period of the award. 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 such as expected term, expected volatility and risk-free interest rates. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. These inputs are subjective and generally require significant analysis and judgment to develop. For all stock options granted to date, the Company calculated the expected term using the SEC simplified method. The Company has limited information on its past volatility and has a limited operating history. Therefore, it has estimated volatility by evaluating the historical volatility of publicly traded industry peer companies. For purposes of identifying these peer companies, the Company considered the industry, stage of development, size and financial leverage of potential comparable companies. The estimated forfeiture rate is derived from the Company’s historical data, and the risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the Company’s stock options. | ||||||||||||||||
There were no stock options granted to employees or non-employee directors during the three months ended September 30, 2013 or 2012. The weighted-average assumptions used to estimate the fair value of stock options granted to employees and non-employee directors during the nine months ended September 30, 2013 and 2012 and the resulting fair values are as follows: | ||||||||||||||||
Nine Months Ended September 30, | ||||||||||||||||
2013 | 2012 | |||||||||||||||
Dividend yield | —% | —% | ||||||||||||||
Risk-free rate | 0.93% | 1.11% | ||||||||||||||
Expected volatility | 61% | 61% | ||||||||||||||
Expected term (in years) | 6.1 | 6 | ||||||||||||||
Grant date fair value | $7.39 | $9.02 | ||||||||||||||
The fair value of restricted stock units granted to employees and non-employee directors is measured by reference to the fair value of the underlying shares on the date of grant. | ||||||||||||||||
Stock-based compensation expense related to stock options granted to employees and non-employee directors was $1.8 million for both the three months ended September 30, 2013 and 2012, and $6.7 million and $5.7 million for the nine months ended September 30, 2013 and 2012, respectively. Stock-based compensation expense related to restricted stock units granted to employees and non-employee directors was $2.1 million and $0.6 million for the three months ended September 30, 2013 and 2012, respectively, and $5.1 million and $1.5 million for the nine months ended September 30, 2013 and 2012, respectively. | ||||||||||||||||
As of September 30, 2013, there was $12.4 million and $23.3 million of unrecognized compensation cost related to stock options and restricted stock units, respectively, which was expected to be recognized over a weighted-average period of 2.2 years and 3.1 years, respectively. | ||||||||||||||||
Stock-Based Compensation Related to Non-Employees | ||||||||||||||||
The Company periodically grants equity awards to non-employees in exchange for goods and services. No awards were granted to non-employees in exchange for goods and services during the three or nine months ended September 30, 2013 and 2012, respectively. | ||||||||||||||||
Stock-based compensation expense for non-employees is based on the fair value of the award on the measurement date, which is the earlier of the date by which the commitment for performance by the non-employee to earn the award is reached and the date on which the non-employee’s performance is complete. Each reporting period, the fair value of the unvested non-employee options or restricted stock units is revalued until the awards vest on the measurement date. | ||||||||||||||||
Non-employee stock-based compensation expense related to stock options was $0.1 million for both the three months ended September 30, 2013 and 2012, and $0.2 million and $0.3 million for the nine months ended September 30, 2013 and 2012, respectively. Non-employee stock-based compensation expense related to restricted stock units was nil and $0.1 million for the three months ended September 30, 2013 and 2012, respectively, and $0.2 million and $0.3 million for the nine months ended September 30, 2013 and 2012, respectively. |

Recently Adopted Accounting Standards | |
In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts of Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”), which amends Comprehensive Income (Topic 220) in the Accounting Standards Codification (“ASC”). These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendments in ASU 2013-02 are effective for the Company’s interim and annual fiscal periods beginning January 1, 2013. The adoption of ASU 2013-02 did not have a material impact on the Company’s consolidated financial statements. | |
In October 2012, the FASB issued ASU 2012-04, Technical Corrections and Improvements (“ASU 2012-04”), which amends a wide range of topics in the ASC. These amendments include technical corrections and improvements to the ASC and conforming amendments related to fair value measurements. The amendments in ASU 2012-04 are effective for the Company’s interim and annual fiscal periods beginning January 1, 2013. The adoption of ASU 2012-04 did not have a material impact on the Company’s consolidated financial statements. | |
In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”), which amends ASU 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment and permits an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with Subtopic 350-30, Intangibles - Goodwill and Other - General Intangibles Other than Goodwill. The amendments in ASU 2012-02 are effective for the Company’s interim and annual fiscal periods beginning January 1, 2013. The adoption of ASU 2012-02 did not have a material impact on the Company’s consolidated financial statements. As of September 30, 2013, the date of the Company’s 2013 annual assessment, the Company’s implied fair value was substantially in excess of its net book value, including goodwill. As such, the Company did not recognize an impairment charge during the three months ended September 30, 2013. |
