If and when Tekashi 6ix9ine comes home from the federal penitentiary he will be able to continue to be Tekashi 6ix9ine.
Peter "Righteous P" Rodgers and "Scumbag Chad" Foster, former 6ix9ine affiliates, had trademarked the name in 2015. However, right before 6ix9ine got locked up, he petitioned to have that trademark revoked.
"Been continuously and extensively used, advertised and promoted nationwide and internationally for more than 4 years, in connection with various of Mr. Hernandez’s entertainment-related goods and services... Mr. Hernandez has sold more than 4 million records in the U.S. and worldwide under the 6ix9ine Marks. His collaboration with culturally significant artists and musical acts, including Nicky [sic] Minaj, Kanye West, and the recording artist known as 50 Cent, demonstrates and confirms Mr. Hernandez’s fame and success," read his petition for cancelation.
6ix9ine's petition was approved earlier this year when neither Rodgers nor Foster responded to it.
Now 6ix9ine can continue to use his name without having to worry about Rodgers and Foster and can trademark it if he wants.
