Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per share equals net loss divided by the weighted average common shares outstanding during the period. Diluted loss per share equals net loss divided by the sum of the weighted average common shares outstanding during the period plus dilutive common stock equivalents. The calculation of loss per common share on a basic and diluted basis was the same for the three month periods ended March 31, 2016 and 2015, because the inclusion of dilutive common stock equivalents and the Warrant issued in connection with the Acquisition would have been anti-dilutive for all periods presented. The Company has granted options to purchase shares of the Company's common stock through employee stock plans with the weighted average options outstanding as of March 31, 2016 and 2015, being 4,456,063 and 4,033,458, respectively, and a warrant to purchase 8,152,174 shares issued to SWK was outstanding as of March 31, 2016, but are anti-dilutive because the Company is in a net loss position.
