Microsoft sued for patent infringement

Vertical Computer Systems claims software giant's .Net technology violates its patent.

Fort Worth, Texas-based Vertical Computer Systems said Friday that it has filed a patent infringement suit against Microsoft. Vertical filed its suit Wednesday in U.S. District Court in Texas, claiming Microsoft's .Net technology infringes on its patent.

A Microsoft representative said that the company had yet to be served with a copy of the lawsuit and said it was premature to comment.
