Patent Portfolio [Abstract]
Patent Portfolio	Note 3 - Patent Portfolio As of March 31, 2012, we own 20 issued U.S. and 26 issued foreign patents, in addition to several pending U.S. and foreign patent applications. Our issued U.S. and foreign patents expire at various times during the period from 2019 to 2024. Some of our issued patents and pending patent applications were acquired by our principal operating subsidiary, VirnetX, Inc., from Science Applications International Corporation, or SAIC, in 2006 and we are required to make payments to SAIC based on cash or certain other values generated from those patents. The amount of such payments depends upon the type of value generated, and certain categories are subject to maximums and other limitations. As of June 30, 2010, we met our maximum royalty payment requirement; however, SAIC is also entitled under certain circumstances to receive a portion of the proceeds paid to us for certain acquisitions of VirnetX or from the settlement of certain patent infringement claims of ours.

The entire disclosure for all or part of the information related to intangible assets.
