High Court Lets Stand Reversal of Award Against Mattel: The U.S. Supreme Court let stand a federal appeals court ruling that reversed a $71-million judgment against El Segundo-based Mattel in a patent infringement lawsuit over its popular Hot Wheels line of toy cars. A jury found in 1989 that the track on which Mattel’s toy cars traveled infringed on the patent of inventor Jerome Lemelson. A federal appeals court in Washington overturned that award last June, ruling that Lemelson’s patent didn’t include a critical feature in the track used in the Hot Wheels system.
