Toyo Tire Holdings of Americas has filed a formal complaint before the United States International Trade Commission (ITC) against 22 manufacturers, importers, and sellers of passenger and light truck tyres, alleging unfair trade practices because they import and/or sell tyres that infringe eight US design patents held by Toyo.

Toyo, whose brands are Toyo Tires and Nitto, said it had developed and introduced “innovative and unique” passenger and light truck tyres and had filed the complaint to protect itself, its customers and associates from “unfair competition” by enforcing intellectual property rights.
