Kawhi Leonard of the Toronto Raptors arrives at the arena before Game Seven of the Eastern Conference Semi-Finals of the 2019 NBA Playoofs on May 12, 2019 at the Scotiabank Arena in Toronto, Ontario, Canada.

Toronto Raptors star Kawhi Leonard is taking on his former sponsor, Nike, in a trademark dispute over his personal logo.

The 2014 NBA champion, filed a lawsuit on Monday, alleging Nike filed a copyright of a logo he originally created without his permission, unbeknownst to him.

Leonard was a Nike-sponsored athlete from October 2011 until September 2014. He now has a sponsorship deal with competitor New Balance and wants to use his "Klaw" logo "on clothing lines, footwear and other products … in connection with sports camps and charity functions, but Nike explicitly objected to such uses," the lawsuit said.

When reached for comment, Nike said the company does not comment on pending litigation.

The lawsuit claims that since his college years, Leonard came up with ideas for a personal logo that would be unique and meaningful to him. The "Klaw" logo in question is an outline of the basketball star's hand that includes his initials and the number 2, which is his jersey number.

"Leonard is known for his extremely large hands. Throughout his career, spectators have noticed Leonard's large hands and they are often described as contributing to his success as a player," the suit reads.

Leonard said he shared the logo with Nike and allowed them to use it on their merchandise but says he never transferred the rights to the logo. "Conversely as the many communications, including text and e-mails show, Leonard permitted Nike to use the Leonard logo for their mutual benefit ... for the term of their contract," it said.
