The organizers of the Grand Slam tennis events (U.S. Open, Wimbledon, etc) promulgate a dress code that minimizes the use of trademarks, so as to prevent tennis players from looking like Nascar drivers. Some manufacturers argued that Aididas’ three stripe design constituted one such identification that should be prohibited. Adidas sued the Grand Slam group, arguing that competitors’ source-identifying design elements were not coming under comparable scrutiny, and that the dress code runs afoul of EC competition rules.
