According to a recent report by the Portland Business Journal, Nike is filing a law suit against Puma North America Inc for patent infringement.
The complaint accuses Puma of using Nike's FlyKnit, Air and cleat assembly technologies despite Nike's requests otherwise. It also outlines the history of FlyKnit and Nike's years of research, design and development of the technology.
Nike launched the technology in 2012 with its FlyKnit Racer and FlyKnit Trainer+ running shoes. The shoes quickly became popular after athletes wore them during the London games and Nike later went on to use the technology in shoes for football (soccer), basketball, tennis and other sports.
