Related Party Transactions	16. Related Party Transactions ipCapital Group, Inc. On October 11, 2011, we engaged ipCapital, an affiliate of John Cronin, who is one of our directors, to assist us in the execution of our strategic decision to significantly strengthen, grow and commercially exploit our intellectual property assets. Our engagement agreement with ipCapital, which has been amended three times, affords us the right to request ipCapital to perform a number of diverse services, employing its proprietary processes and methodologies, to facilitate our ability to identify and extract from our current intellectual property base new inventions, potential patent applications, and marketing and licensing opportunities. For the years ended December 31, 2016 and 2015, there were no services performed, additional charges incurred or payments made to ipCapital under the agreement. In addition to the fees we agreed to pay ipCapital for its services, we issued ipCapital a five-year warrant to purchase up to 26,667 shares of our common stock at an initial price of $3.90 per share. Half of the warrant (13,333 shares) has a time-based vesting condition, with such vesting to occur in three equal annual installments. The first, second, and third vesting installments occurred on October 11, 2012, 2013, and 2014. The remaining 13,333 shares became fully vested upon the completion to our satisfaction of all services that we requested from ipCapital under the engagement agreement, prior to the signing of the amendments. Such performance was deemed satisfactory during 2012. We believe that these fees, together with the issuance of the warrant, constitute no greater compensation than we would be required to pay an unaffiliated person for substantially similar services. The exercise price of the warrant issued to ipCapital could be reset to below-market value. Consequently, we have concluded that such warrant is not indexed to our common stock; thus, we will accrete the fair value of the warrant as a liability over the anticipated service period. Additionally, in accordance with the liability method of accounting, we will re-measure the fair value of the then-outstanding warrant at each future balance sheet date and recognize the change in fair value as general and administrative compensation expense. (See Note 9) We recognized $(2,300) and $(18,100) as a component of general and administrative expense during the years ended December 31, 2016 and 2015, respectively, resulting from the change in fair value. The warrants expired on October 11, 2016. ipCapital Licensing Company I, LLC In February 2013, we entered into an IP Brokerage agreement with ipCapital Licensing Company I, LLC (“ipCLC”) (the “IP Brokerage Agreement”). At the time that we entered into this agreement, John Cronin was a partner at ipCLC. He is no longer affiliated with ipCLC. Pursuant to the IP Brokerage Agreement, we engaged ipCLC, on a no-retainer basis, to identify and present us with candidates who may be seeking to acquire a certain limited group of our patents unrelated to our current business strategy. In June 2016, we determined that the IP Brokerage Agreement is no longer in effect since ipCLC no longer exists as an entity.
