Disclosure Of Compensation Related Costs, Share-Based Payments [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Since inception, the Company has incurred losses from operations and as a result has not recorded income tax expense. Benefits related to net operating loss carryforwards and deferred items have been fully reserved since it was not more likely than not that the Company would achieve profitable operations. The Company applied for state research and development refundable credits for the years ended December 31, 2006 through 2009. In April 2012, the Company received $613,397 relating to these credits for the years 2006 through 2009, which is reflected as income tax benefit in the accompanying statement of operation. The Company currently does not expect to collect additional credits for subsequent years.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
