U.S. shoe maker Skechers has filed a lawsuit in California with Reebok over patent infringement for the Go Walk sports shoe.
Reebok is a subsidiary of the world's second largest manufacturer of sportswear and accessories, the German company Adidas AG.
According to the agency, the plaintiff demands compensation and penalties, and also seeks an injunction against Reebok, according to the plaintiff who violated Skechers patent rights and conducts unfair competition.
Skechers also said it will file a similar lawsuit against any retailer selling Reebok's Walk Ahead RS shoe model.
At the same time, as previously reported, both companies were fined at different times. Skechers in May ordered 40 to be paid millions of dollars in fines for unfair advertising, which claimed that Shape-ups help lose weight without going to the gym.
The U.S. Federal Trade Commission (FCS) was displeased by an advertisement in which Skechers said wearing specially designed athletic shoes leads to weight loss, improved posture and increased muscle tone of the lower body without additional physical exertion. According to the FCS, the results of clinical trials that Skechers referred to in commercials are unreliable.
The FCS in September 2011 also fined Reebok, which had to pay $ 25 million to disappointed buyers of the muscle-pumping Easy Tone sneakers.
