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, patent rights 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 months ended March 31, 2014, the effect of the insurance policies that have been issued was not material to the Company’s results of operations or financial condition. |

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, 2013. | |
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 months ended March 31, 2014 are not necessarily indicative of the results that may be expected for any subsequent interim period or for the year ending December 31, 2014. | |
There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2014, as compared to the significant accounting policies presented under the heading “Basis of Presentation and Significant Accounting Policies” in Note 2 of the Notes to Consolidated Financial Statements in Part II, Item 8 of the Company’s Annual Report on Form 10-K filed with the SEC on March 10, 2014. |

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

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 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 contingencies was recorded as of March 31, 2014 or December 31, 2013. | |
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. In March 2014, Volkswagen voluntarily dismissed its complaint against the Company without prejudice. | |
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. The Company had no liabilities recorded for these agreements as of March 31, 2014 or December 31, 2013. 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 March 31, 2014, the Company had a total of 31 active policies and had recorded a reserve of $0.6 million, net of amounts recoverable from reinsurers, for known and incurred but not reported claims that represent estimated claim costs and related expenses. | |
The Company regularly reviews its loss reserves using a variety of actuarial techniques and updates them as its loss experience develops. |

In October 2013, the Board of Directors approved net-share settlement for tax withholdings on RSU vesting. During the three months ended March 31, 2014, the Company withheld issuing 55,648 shares of its common stock based on the value of the RSUs on their vesting dates as determined by the Company’s closing common stock price. Total payments for the employees’ minimum tax obligations to taxing authorities were $0.9 million for the three months ended March 31, 2014, and were recorded as a reduction to additional paid-in capital and reflected as a financing activity within the condensed consolidated statements of cash flows. The net-share settlements reduced the number of shares that would have otherwise been issued on the vesting date and increased the number of shares reserved for future issuance under the 2011 Plan. | ||||||||||||||||
Stock-Based Compensation Related to Employees and Directors | ||||||||||||||||
The fair value of RSUs granted to employees and directors is measured by reference to the fair value of the underlying shares on the date of grant. | ||||||||||||||||
PBRSUs contain both service and market conditions that affect the quantity of awards that will vest. During the three months ended March 31, 2014 and 2013, the Company granted 200,000 and 125,000 PBRSUs, respectively. The Company estimates the grant date fair value of PBRSUs using the Monte Carlo simulation model. The weighted-average assumptions used to estimate the fair value of PBRSUs and the resulting fair values are as follows: | ||||||||||||||||

Stock-based compensation expense related to PBRSUs granted to employees was $0.2 million and less than $0.1 million for the three months ended March 31, 2014 and 2013, respectively. | ||||||||||||||||
As of March 31, 2014, there was $8.9 million and $35.0 million of unrecognized compensation cost related to stock options and RSUs, including PBRSUs, respectively, which is expected to be recognized over a weighted-average period of 2.0 years and 3.1 years, respectively. Future grants of equity awards will increase the amount of stock-based compensation expense to be recorded. | ||||||||||||||||
Stock-Based Compensation Related to Non-Employees | ||||||||||||||||
The Company periodically grants equity awards to non-employees in exchange for goods and services. No equity awards were granted to non-employees in exchange for goods and services during the three months ended March 31, 2014 and 2013. | ||||||||||||||||
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 stock option or RSU is revalued until the award vests on the measurement date. | ||||||||||||||||
Non-employee stock-based compensation expense related to stock options was nil and $0.1 million for the three months ended March 31, 2014 and 2013, respectively. Non-employee stock-based compensation expense related to RSUs was nil and $0.1 million for the three months ended March 31, 2014 and 2013, respectively. |

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. The Company’s effective tax rate, including the impact of discrete benefit items, was 38% and 36% for the three months ended March 31, 2014 and 2013, respectively. The higher effective tax rate for the three months ended March 31, 2014 was primarily due to an increase in nondeductible executive compensation which was partially offset by a decrease in book expense for nondeductible incentive stock options. | |
The Company’s 2010 tax year is currently under examination by the State of California Franchise Tax Board. The Company does not expect a material impact on its condensed consolidated financial statements as a result of this examination. The 2010 through 2012 tax periods remain open to examination by the Internal Revenue Service and the 2009 through 2012 tax periods remain open to examination by most state tax authorities. For the Company’s foreign jurisdictions, the 2009 through 2012 tax years remain open to examination by their respective tax authorities. |

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. | ||||||||||||||
