Copycat tread leads to Bridgestone lawsuit
Bridgestone Americas Tire Operations has filed a patent infringement and unfair trade practices suit against US based retreader and price-driven online tyre retailer TreadWright, claiming the company copied the tread design on its Dueler A/T Revo tyre, which is protected by a 2003 patent. According to Bridgestone, TreadWright initially used the design on its Sentinel tyre. After it issued a cease-and-desist letter to the company in 2013, TreadWright stopped selling that tyre and released a new tyre, called the Watchman, which, according to Bridgestone, had the same tread design.
