Case Name: Inalfa Roof Systems, Inc. v. Roof Systems Germany
Docket Number: 2:2011-cv-12548
Date Filed: 6/13/2011
Judge: Hon. Julian A. Cook
Status: Closed

Inalfa Roof Systems (“Plaintiff”) filed suit against Roof Systems Germany GmbH; Meritor, Inc.; Inteva Products, LLC; and Inteva Products USA, LLC (“Defendants”) for declaratory judgment of invalidity of U.S. Patent No. 7,178,862 (“the ‘862 patent”), entitled “Sliding Roof System.” The ’862 patent was based off of European Patent EP1586457B1, and Plaintiff claimed that the patentability of the European patent was contested. Plaintiff asserted that it had received a letter from Defendants, claiming ownership of the patent and contending that the actions of Plaintiff in manufacturing and selling the Cadillac SRX Sliding Roof System in the U.S. constituted a violation of Defendants’ patent. Plaintiff alleged that the European patent and the ’862 patent were invalid and requested that the court declare that the patent was invalid and award Plaintiff attorney fees incurred as a result of Defendants’ improper demand. On May 10, 2012, the parties entered a Stipulation of Dismissal with Prejudice with the District Court.
