VirnetX Launches Patent Lawsuit Against Microsoft

Despite Microsoft Signing $200M Deal for Use of Technology in 2010

Internet security software and technology company VirnetX is hauling Microsoft back into court, claiming the technology giant’s VoIP service, Skype, violates its patents.

VirnetX today filed a complaint against Microsoft in the United States District Court for the Eastern District of Texas alleging “willful patent infringement regarding six patents owned by VirnetX.”

Microsoft purchased Skype after signing a limited license with VirnetX in May 2010. At that time, Microsoft’s made a one-time payment of $200 million to VirnetX for use of its technology in Microsoft products. The settlement came after three years in and out of court.

VirnetX says Skype is not included in its prior license and deserves more compensation from Microsoft as a result.

“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 VirnetX CEO and president Kendall Larsen in a press release. “We look forward to quickly resolving this matter.”

The company is seeking both damages and injunctive relief.

VirnetX is well known for hauling companies into court for alleged patent infringement. The firm has successfully sued a number of large companies, including Apple.

After winning a $368-million patent verdict over Apple last November, the Internet security software and technology company quickly launched a new lawsuit against the iPhone maker.

The new suit, which is currently before the courts, claims the iPhone 5, iPod Touch 5th Generation, iPad 4th Generation, iPad Mini, and the latest Macintosh computers, violate these patents.

These products were not included in the previous lawsuit, launched in 2011, due to their release dates.

A press release by VirnetX indicates it is seeking both damages and injunctive relief from Apple.

If VirnetX is successful in its suits against Microsoft and Apple, it stands to receive some hefty compensation cheques.
