Briggs & Stratton files counterclaim in patent case

Milwaukee-based Briggs & Stratton has filed a counterclaim in a U.S. district court in Omaha against Beatrice lawnmower maker Exmark Manufacturing, according to the Journal Star.

Exmark, a division of the Toro Co., sued Briggs & Stratton and Schiller Grounds Care in May, alleging their mowers infringe on its patents.

At issue is Exmark’s 863 Patent, which covers multi-blade mowers equipped with baffles between blades, allowing the mower to be converted from a mulching to a side-discharge mower.
