Microsoft in patent battle over Visual Studio
C|Net | at | by Mike
Aiming to head off further legal action against its customers, Microsoft is asking a federal court to declare that its Visual Studio product doesn't violate patents from WebXchange.
In a suit filed last week in San Francisco, Microsoft seeks a declaration that WebXchange's patents are invalid, unenforceable, or that Microsoft does not infringe on the patents. The move comes after WebXchange sued three Microsoft customers earlier this year in Delaware.
In its suit, Microsoft said that WebXchange's lawsuit has "placed a cloud over Visual Studio software, Web services, and the SOAP protocol."
