Case Name: Federal-Mogul World Wide, Inc. et al v. Mahle GmbH et al
Docket Number: 2:11-cv-10675-JAC-MAR
Date Filed: 2/18/2011
Judge: Hon. Julian A. Cook
Preliminary Injunction: Denied
On February 18, 2011, Plaintiffs Federal-Mogul World Wide, Inc. and Federal-Mogul Corp. filed suit against Defendants Mahle GmbH and Mahle Engine Components USA, Inc. infringement of U.S. Patent Nos. 6,260,472 (“the ‘472 patent”) and 6,557,457 (“the ‘457 patent”) related to piston designs and assemblies.
Plaintiffs and Defendants are large competitor suppliers of engine components. In 1998, Plaintiffs acquired T&N Industries, a company once owned by Defendants, after the FTC issued an order to Defendants to divest themselves of T&N. Plaintiffs argued that Defendants, using trade secrets taken from T&N, were violating the ‘472 patent for a one-piece engine piston formed by a friction welding process by producing the “MonoWeld” piston. Plaintiffs similarly argued that Defendants violated the ‘457 Patent, a method patent relating to piston assembly that utilizes a coating of special chemical material on various components in place of conventional bushings. Plaintiffs also brought claims of unfair competition, violations of the Michigan Uniform Trade Secrets Act (MUTSA), and breach of contract against Defendants. On May 23, 2011, Defendants brought a motion requesting dismissal and judgment regarding all of Plaintiffs’ claims. Ruling on the motion on September 27, 2011, Judge Cook dismissed Plaintiffs’ claims concerning the ‘457 patent, breach of contract, and acts of unfair competition, but denied the motion with respect to the ‘472 patent and MUTSA violation. The same day, the Judge also denied Plaintiffs’ motion for preliminary injunctive relief. On November 8, 2012, Judge Cook ordered the case dismissed after Plaintiffs filed notice of voluntary dismissal.
