Last week, Marc Stein of the New York Times reported that the Los Angeles Clippers, one of the teams desperate to sign Leonard this summer when he becomes a free agent, were attempting to buy the "Klaw" logo from Nike as part of their pitch to bring him to L.A.
According to Portland Business Journal, Leonard has filed a federal lawsuit against Nike, claiming that the logo was actually his design.
"Leonard intends to use the logo on clothing lines, footwear and on other products and, among other things, in connection with sports camps and charity functions, but Nike explicitly has objected to such uses".
Representatives for Leonard and Nike did not immediately return Sole Collector's request for comment.
During his agreement with the company, the two parties started discussions about creating a logo to add onto merchandise to be sold under the Nike agreement, the lawsuit said.
But, he claims that unbeknownst to him, "Nike filed an application for copyright registration of his logo and falsely represented in the application that Nike had authored the logo".
Leonard and the Raptors will face the Warriors for Game 3 of the Finals at Oakland's Oracle Arena on Wednesday night. His elevated play during the postseason has helped Toronto reach its first-ever NBA Finals.
According to court documents obtained by The Blast, Leonard claims that he created a unique logo for himself after he was drafted to the National Basketball Association in 2011. The Warriors tied the series at 1-1 with Sunday's Game 2 win in Toronto. He said he started to create the logo while he was still in college.
According to ESPN, Nike responded to Leonard's claims back in March.
