In December 2005, Michelin alerted more than 5,000 dealers in various countries of the risks involved in marketing look-alike tires from Asia. These look-alike products copy the tread patterns of Michelin truck tires, and while the two treads may look alike, the look-alikes may not deliver the same grip or longevity of performance as an authentic Michelin tire.
Nonetheless, unauthorized copies of Michelin tread patterns can still be found in the market, notably under the Double Coin brand. That's why Michelin has taken legal actions against dealers of these products in all countries in which they have been identified by Michelin sales teams.
In the United States, Michelin North America Inc. has initiated a suit against the Chinese Manufacturers Alliance LLC (CMA). This patent and copyright infringement lawsuit, filed in federal court in Greenville, S.C., accuses CMA of importing and selling the Double Coin RT606 and the DynaTrac RS330 tires, both of which utilize unauthorized copies of the patented Michelin XZE tread pattern. Michelin North America is seeking an injunction against further distribution, as well as monetary damages.
