UPDATE: VirnetX Files New Suit Against Microsoft Citing Willful Infringement

VirnetX™ Holding Corporation

, an Internet security software and technology company, announced today that on April 22, 2013, it filed a complaint against Microsoft Corporation

in the United States District Court for the Eastern District of Texas, Tyler Division.  The complaint includes allegations of willful patent infringement regarding six patents owned by VirnetX, U.S. Patent Nos. 6,502,135,  7,188,180,  7,418,504,  7,490,151,  7,921,211, and 7,987,274.  Specifically, the complaint references Microsoft's Skype products as infringing the VirnetX patents.  Skype was purchased after the limited license was signed between Microsoft and VirnetX.    This infringement falls outside of the scope of the prior license.  In its complaint, VirnetX seeks both damages and injunctive relief. "Although Microsoft previously signed a patent license with Virnetx, we believe they are infringing our patents in ways that are outside the scope of the original license," said Kendall Larsen, VirnetX CEO and President. "We look forward to quickly resolving this matter."
