Nike sued Lululemon Athletica on Monday, saying that at least four of the Canadian athletic apparel company’s footwear products infringe its patents.
Nike in a complaint filed in Manhattan federal court said it suffered economic and irreparable damages from Lululemon’s sale of Blissfeel, Chargefeel Low, Chargefeel Mid and Strongfeel shoes to Lululemon.
Nike says three of its patents relate to textiles and other elements, including one that deals with how footwear will behave when force is applied.
The Beaverton, Oregon-based company is seeking unspecified damages.
Lululemon, based in Vancouver, British Columbia, did not immediately respond to requests for comment.
