Patent holding company IP Innovation has filed a patent infringement lawsuit against Red Hat and Novell, claiming their Linux products violate a patent on "user interface with multiple workspaces for sharing display system objects." The lawsuit seems to target the graphic interfaces used by Red Hat’s and Novell’s Linux products, rather than the core Linux operating system, but the suit may nontheless raise doubts amongst organizations and enterprises concerned Linux may be vulnerable on the intellectual property front—a perception software giant Microsoft would be all-to-happy to encourage.
