Rpx License Agreement
7. RPX License Agreement	On November 23, 2015, the Company and RPX Corporation (“RPX”) entered into a Patent License Agreement (the “RPX License Agreement”) under which the Company granted RPX the right to sublicense various patent license rights to certain RPX members. The consideration to the Company included: (i) the transfer to the Company for cancellation of its remaining outstanding Series I Redeemable Convertible Preferred Stock (the “Series I Preferred Stock”), as to which a $5,000,000 mandatory redemption payment would have been due from the Company on or by December 31, 2015; (ii) the transfer to the Company for cancellation of 13%, or 57,076 shares, of its Series H Convertible Preferred Stock (the “Series H Preferred Stock”) then held by RPX, having a total carrying amount of $4,765,846 at the time the stock was issued to Rockstar; (iii) cancellation of the only outstanding security interest on 101 of the Company’s patents and patent applications that originated at Nortel Networks (“Nortel”) and were purchased by the Company from Rockstar, which security interest had previously been transferred to RPX by Rockstar (“RPX Security Interest”); and (iv) $300,000 in cash to the Company. ASC 260-10-S99-2, Effect on the Calculation of Earnings per Share for the Redemption or Induced Conversion of Preferred Stock, requires the gain or loss on extinguishment of equity-classified preferred stock to be included in net income per common stockholder used to calculate earnings per share (similar to the treatment of dividends paid on preferred stock). The difference between (1) the fair value of the consideration transferred to the holders of the preferred stock and (2) the carrying amount of the preferred stock (net of issuance costs) is subtracted from (or added to) net income to arrive at income available to common stockholders in the calculation of earnings per share. The carrying value of Series I Preferred Stock and Series H Preferred Stock on the extinguishment date was estimated at approximately $5.0 million and $4.8 million, respectively. This resulted in the Company receiving cash from RPX of $0.3 million, a deemed dividend of approximately $9.5 million, short term deferred revenue $0.3 million and long term deferred revenue of $0.3 million. The deferred revenue was amortized quarterly. While the license granted to RPX is non-exclusive and the duration of the license is for the life of the patents, the Company’s ongoing obligations in the arrangement is to provide certain specific RPX licensors with a non-exclusive license to any new patents that may be acquired by or exclusively licensed to the Company during the two-year period following the effective date of the agreement. Therefore, the Company will recognize $0.6 million revenue ratably over the two-year period that it is obligated to provide these RPX licensees with licenses to such new patents. At December 31, 2015, the Company recorded approximately $31,000 in revenue.
