Nike this week accused its main rival Adidas of infringing the patents on its construction of high-tech Flyknit sneakers.
The American sneaker giant, based near Beaverton, filed a lawsuit Wednesday against its German counterpart, which is headquartered in Portland.
He said Adidas ripped off its “game-changing” Flyknit technology, which is used to make one-piece knitted uppers for sneakers that use less material and generate less waste. He says Adidas has appropriated the technique for dozens of products, including some in its Primeknit line.
Adidas denied this claim on Thursday.
“We are currently analyzing the complaint and will defend ourselves against the allegations,” the company said in a statement. “Our Primeknit technology is the result of years of dedicated research and shows our commitment to sustainability.”
The lawsuit, filed in the United States District Court in Portland, was first reported by the Portland Business Journal. Nike is seeking a court order for Adidas to stop using the patented designs and awarding damages.
Nike also on Wednesday called on the United States International Trade Commission to investigate Adidas for infringing its patents and to block the import or sale of products that infringe them.
Last month, Nike settled three lawsuits in a long-standing dispute with fellow competitor, California-based Skechers. He had accused Skechers of incorporating Nike patented design elements into his sneakers.
