Footwear giant Skechers USA Inc has filed a multi-million dollar lawsuit against LA Gear amid claims it used its design in a competing line of less expensive footwear and its likeness could confuse shoppers, the LA Times reported on Thursday. According to the paper, Skechers said it has patents for the athletic sneaker, as well as Sport Noogies and Sport Gators shoes, and alleges LA Gear is using Skechers' logo and likeness to confuse consumers.
