Footwear giant Nike (NKE.N) filed federal lawsuits on Monday against rivals New Balance and Skechers (SKX.N), accusing them of infringing patents related to Nike’s technology for making upper portions of sneakers.
Nike has previously sued Adidas (ADSGn.DE), Puma (PUMG.DE) and Lululemon (LULU.O) for infringing Flyknit patents. Adidas and Puma have settled their lawsuits, while Nike’s case against Lululemon is still ongoing.
Beaverton, Oregon-based Nike’s website said that its Flyknit technology “uses high-strength fibers to create lightweight uppers with targeted areas of support, stretch and breathability.” The lawsuits said the patented technology allows it to make high-performance uppers with reduced materials and waste.
Nike asked the courts for an unspecified amount of money damages and court orders permanently blocking New Balance and Skechers from infringing the patents.
