Stemco-ATDynamics claims GreenTail is patent infringement

Stemco, an EnPro Industries company, has announced that its subsidiary ATDynamics filed a Motion for Preliminary Injunction against Ridge Corp. in the United States District Court for the Central District of California on May 19, 2015.

ATDynamics has asked the court to enjoin Ridge Corp. from making or selling the GreenTail aerodynamic device on the basis that the GreenTail infringes on at least 30 claims from Stemco-ATDynamics’ extensive patent portfolio. Those patents include TrailerTail products.

“We invest substantial resources into developing innovative and effective drag-reducing technologies for our customers,” said Bob Montgomery, vice president of the Innovative Tire & Mileage Solutions Group for Stemco.

Stemco-ATDynamics has engaged attorneys Timothy Carroll and Kourtney Merrill of Perkins Coie to handle the case.
