March 22, 2010 - After winning $105.75 million in damages from Microsoft, VirnetX announced in the same week that it had filed a second patent infringement lawsuit against Microsoft.
This time, VirnetX claims that Microsoft has violated the same two patents, 6,502,135 and 7,188,180, both of which cover specific ways of better securing IP-based communications through VPNs and other technologies. This time the infringement concerns Windows 7 and Windows Server 2008 R2.
