The lawsuits said that several New Balance athletic shoes and Skechers sneakers misuse Nike's patented "Flyknit" technology for running, soccer and basketball shoes.
Nike has previously sued Adidas (ADSGn.DE), Puma (PUMG.DE) and Lululemon (LULU.O) for infringing Flyknit patents.
Representatives for Nike, New Balance and Skechers did not immediately respond to requests for comment on the Monday lawsuits.
Nike sued Manhattan Beach, California-based Skechers in Los Angeles, claiming that shoes, including Skechers' Ultra Flex and Glide Step brands, infringed on its patents.
Nike asked the courts for an unspecified amount of money damages and court orders permanently blocking New Balance and Skechers from infringing the patents.
