Yokohama Initiates Patent Proceedings Against Hangzhou Zhongce
The fortunes of Hangzhou Zhongce in the US have received another blow. Only seven months after the beginning of the now notorious Foreign Tire Sales recall of the company’s Westlake, Compass and YKS branded tyres, the Chinese manufacturer is facing legal action regarding the tread pattern used on some of the tyres it produces.
On January 17 the Yokohama Rubber Company filed an intellectual property infringement complaint with the Miami office of the Florida Southern District Court. The document filed by Yokohama claims that Hangzhou Zhongce has copied the tread pattern design from its S.drive tyre range, a design patented in the US by Yokohama in November 2005. The alleged copycat tyres are marketed under the Sumo brand name, the private brand belonging to Singapore’s Stamford Tyres, and the models in question are the Sumo Firenza ST-08 and Sumo Akina ST-08.
