Alfonso Ribeiro is attempting to sue Epic Games — the creators of Fortnite — and 2K Games — the creators of the NBA 2K series — for allegedly ripping off his infamous Carlton Dance. But according to TMZ, he doesn’t actually own the moves, making both cases extremely difficult to prove.

A registration specialist for the U.S. Copyright Office told Ribeiro’s attorney his request to secure the rights to the dance is being denied. The specialist added Ribeiro’s moves amount to nothing more than a “simple dance routine.”

The expert went on to say, “The combination of these three dance steps is a simple routine that is not registrable as a choreographic work.”

The current host of America’s Funniest Home Videos failed to copyright The Carlton Dance in the 27 years since he debuted it on The Fresh Prince of Bel-Air.

He also admitted on camera the dance was inspired by Courtney Cox and Eddie Murphy.

While Ribeiro’s lawsuits are still active, the copyright issue will likely hurt both cases.
