The U.S. Supreme Court refused to revive a $31.6 million patent-infringement award won by a Metso Oyj unit in a suit against Terex Corp. over a machine that sorts rocks and gravel.
The high court today turned away an appeal by Metso Minerals Inc. of a lower court ruling that threw out the jury verdict in the company’s favor. The lower court said Metso’s patent covered an obvious variation of existing machinery.
Helsinki-based Metso makes paper machines in addition to rock crushers. Terex is a Westport, Connecticut-based maker of cranes and lifts.
The case is Metso v. Powerscreen International, 13-565.
