Nike is suing lululemon. At least four apparel companies have extended a history of contentious litigation between the two companies in patent infringements involving shoes. In a complaint filed Monday in Manhattan federal court, Nike alleges that it suffered financial and irreparable harm due to Lululemon’s sale of its Chargefeel Mid, Chargefeel Low, Blissfeel, and Strongfeel shoes.
Nike says its three patent claims focus on textile elements such as knit materials, webbed areas and the tubular structure of the footwear. One patent claim also refers to footwear performance. The Oregon-based company is seeking unspecified damages. Vancouver-based Lululemon did not immediately respond to a request for comment.
Lululemon launched its first women’s running shoe in March, marking the company’s official foray into the sneaker market. Chargefeel, the second in the lineup, was released in July for running and training.
A Canadian apparel maker has been accused of infringing on six patents related to a home-use Mirror fitness device and related mobile applications. In that case, Nike is seeking three times his damages. Nike filed a patent in 1983 claiming to have invented a device that measures a runner’s speed, calories burned, distance traveled and elapsed time. Interactive workout platform Mirror guides users through cardio classes and other exercises. The complaint points to similarities in technology that allows users to compete with other users, track performance, and target specific exercise levels.
Lululemon’s statement at the time said, “The patent in question is too broad and invalid. We are confident in our position and look forward to defending it in court.”
