Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	16. Related Party Transactions Tamalpais Partners LLC Steven Ledger, former Chairman of our Board of Directors, is the founder and managing partner of Tamalpais Partners LLC, (“Tamalpais”) a business consulting firm. On March 17, 2014, contemporaneous with Mr. Ledger’s resignation from our board, we mutually agreed with Mr. Ledger to terminate our consulting agreement with Tamalpais. We paid Tamalpais $12,000 and $18,000 for the three-month periods ended March 31, 2014 and 2013, respectively, for services rendered to us under the terms of this consulting agreement. No amounts were due Tamalpais at either March 31, 2014 or 2013. When he resigned as our Chairman, we entered into a short-term consulting agreement with Mr. Ledger that was separate from the terminated agreement with Tamalpais. Under that exclusive consulting agreement, Mr. Ledger began providing consulting services to our Board of Directors for a term that commenced upon his resignation, which will end on August 15, 2014. The consulting agreement also provides that Mr. Ledger’s then currently unvested options to purchase our common stock granted during his term as a director will continue to vest during the term of the consulting agreement in accordance with their original terms. In addition, the agreement provides that the period in which to exercise such options will be extended through the end of 2014. Mr. Ledger will also be reimbursed for his reasonable expenses incurred in connection with rendering services to our Board of Directors in accordance with our expense reimbursement policies. The consulting agreement also contains confidentiality, mutual non-disparagement and independent contractor-related provisions. ipCapital Group, Inc. On October 11, 2011, we engaged ipCapital Group, Inc. (“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 three-month periods ended March 31, 2014 and 2013, we paid ipCapital an aggregate of $0 and $5,000, respectively, for services performed under the engagement agreement, as amended. For the three-month periods ended March 31, 2014 and 2013, we had incurred additional charges from ipCaptial for work performed during such periods of $0 and $10,000, respectively. Such amounts were reported in accounts payable. In addition to the fees we agreed to pay ipCapital for its services, we issued ipCapital a five-year warrant to purchase up to 400,000 shares of our common stock at an initial price of $0.26 per share. Half of the warrant (200,000 shares) has a time-based vesting condition, with such vesting to occur in three equal annual installments. The first two vesting installments occurred on October 11, 2012 and October 11, 2013, respectively, with the remaining vesting installment to occur on October 11, 2014. The remaining 200,000 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 performing 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 and should be recorded as a liability. We recognize the warrants liability over their vesting period, and in accordance with the liability method of accounting, we re-measure the fair value of the accrued warrants at each balance sheet date and recognize the change in fair value as general and administrative compensation expense. (See Note 4). We recognized $49,800 and $73,500 as a component of general and administrative expense during the three-month periods ended March 31, 2014 and 2013, respectively, resulting from the change in fair value. ipCapital Licensing Company I, LLC On February 4, 2013, we entered into an IP Brokerage agreement with ipCapital Licensing Company I, LLC (“ipCLC”). John Cronin is a partner at ipCLC. Pursuant to the agreement, we have 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. If during the applicable term we enter into an agreement with any candidate presented by ipCLC to acquire or otherwise exploit the covered patents, we will pay ipCLC a fee of ten percent (10%) of the royalties, fees, and other consideration paid over the life of the agreement. The agreement is effective as of February 4, 2013, and will end 18 months after we or ipCLC serve 60 days written notice of termination to the other party (with earlier termination possible in the event of a material breach). The agreement provides for customary confidentiality undertakings, limitations on ipCLC’s total liability and mutual indemnification provisions. We believe the terms of the agreement are fair and reasonable to us and are at least as favorable as those that could be obtained on an arms’ length basis.
