Converse Accuses Rivals Of Copying Its Shoes
Nike (Sao Paolo: NIKE34.SA - news) 's Converse brand is suing 31 rival companies, saying they are selling knock-off versions of its famous Chuck Taylor shoes.
The company - based in Massachusetts - accuses firms including Skechers USA (NYSE: SKX - news) and Ralph Lauren of infringing trademarks that cover the look of the shoe and the diamond pattern on the bottom of the sole.
It said lookalike Chuck Taylor shoes have become more common in recent years and it had served about 180 so-called "cease and desist" letters related to the issue since 2008.
The other brands covered by the lawsuits include Walmart stores, FILA, Ed Hardy and K-Mart.
Converse, which was bought by Nike in 2003, filed the case at the Eastern District of New York and at the International Trade Commission.
Sales of the brand rose 16% in the most recent trading quarter to $575m (£361m).
