SANTA CLARA, CA -- Sigrity Inc. and The Research Foundation of State University of New York (SUNY) have filed a lawsuit against Ansoft Corp. and ANSYS, Inc. for infringement of U.S. Patent No. 5,504,423 titled "Method for Modeling Interactions in Multilayered Electronic Packaging Structures.”

The Research Foundation is the owner and Sigrity is the exclusive licensee of this patent.

The suit was filed on July 21, 2008 against Ansoft and alleges that Ansoft’s products, including its SIwave product, infringe the patent. An amended complaint adding ANSYS as a defendant was filed on August 5, 2008 as a result of ANSYS’s acquisition of Ansoft, which was effective July 31, 2008.
