Microsoft will be back in U.S. District Court in East Texas to defend itself against another patent-infringement case, being brought brought by real-time communications vendor VirnetX Inc. and involves three VirnetX patents which that company claims that Microsoft is using its technology in Windows Server 2003, XP, Vista, Live Communications Server, Windows Messenger, Office Communicator and various versions of Office. VirnetX is seeking triple damages, injunctive relief and costs in the case. SAIC is named as an involuntary co-plaintiff in lawsuit, which VirnetX filed in 2007. (VirnetX, a subsidiary of VirnetX Holdings, is “focused on commercializing a patent portfolio for securing real-time communications over the Internet,” explains the company in its November 10-Q. “These patents were acquired by our principal operating subsidiary, VirnetX Inc., from Science Applications International Corporation.”) VirnetX is paying McKool a fixed fee of $3 million and a contingency fee of 8% of the litigation proceeds, according to its 10-Q.
