InterTrust Technologies, a small US company that develops
digital rights management (DRM) software, has said that it has
further expanded a patent infringement lawsuit against Microsoft
which it hopes will block the launch of the Windows XP operating
system, scheduled for 25th October.
InterTrust yesterday announced that it has added three more
patents to its lawsuit against Microsoft filed earlier this year.
InterTrust alleges Microsoft's .NET implementation infringes
various InterTrust patents covering secure computing technologies
and DRM. The complaint further alleges that the "product
activation" features of Windows XP, OfficeXP and other Microsoft
products also infringe its patents.
In the lawsuit InterTrust seeks unspecified damages and an
injunction prohibiting further infringement, such as by Microsoft's
continued distribution of its .NET implementation, Windows XP and
Windows ME operating systems, Office XP, Visio2002, Windows Media
Player, Microsoft Reader, Digital Asset Server products, and other
Microsoft application, server, and operating system products.
Microsoft has denied all the allegations to date.
