Nike files a lawsuit against Adidas. According to Newratings.com, Nike filed a patent infringement suit against Adidas back in February. Nike claims that Adidas used similar technology in their shoes that infringed on the patents of their Nike Shox technology. Nike has 19 patents on the Shox technology. Nike also specifically said that the Adidas 1 running shoe (the one with the computer chip inside) and the Kevin Garnett Adidas basketball shoes infringed on Nike's Shox patents. The news article also mentioned that Adidas is now the second largest shoe company in the world after recently buying and taking over Reebok.
If Adidas bought Rbk it's basically Nike against Adidas now cuz Nike owns Converse and Jordan
