VirnetX, a company which uses IP to license to other companies has already won a $200 million patent settlement from Microsoft in 2010. Yesterday, VirnetX filed another suit against Microsoft in the East Texas judicial district.
This new lawsuit is related to six patents that are alleged to cover Skype, Lync, and other instant-messaging platform. Last time Microsoft settled the litigation for $200 million after the jury awarded a fine of $105.7 million.
VirnetX now notes that the license “was explicitly limited in scope, and Microsoft is not licensed to practice VirnetX’s technology in certain excluded ways, particularly across non-Windows platforms.”
Microsoft is yet to comment on this issue.
