Raptors superstar Kawhi Leonard has filed a lawsuit against Nike to regain control of his "Klaw" logo that he designed after the sports giant filed an application for copyright registration of his logo. Leonard's lawsuit claims that Nike filed the registration after he signed an endorsement deal and allowed Nike " to use on certain merchandise the logo he created while Leonard continued to use the logo on non-Nike goods." 

The lawsuit also revealed that Nike and Leonard went back and forth several times, with Nike telling Leonard in March that "it owns all intellectual property rights in the Leonard Logo and demanding that Leonard immediately cease and desist from what Nike claimed was the unauthorized use of the Leonard Logo."
