A legal dispute over the AI-generated meme character Tung Tung Sahur is heading towards a September hearing in a US federal court, with wider implications for entertainment companies using AI-created content. Spyder Games, linked to the Roblox game Steal A Brainrot, argues that Mementum Lab has no enforceable rights, while Mementum says companies should not be able to commercially exploit AI-assisted works without permission or payment to their creators.

Mementum licensed Tung Tung Sahur from its Indonesian creator, Noxa, and had already secured a deal involving Fortnite before seeking a similar agreement with Spyder’s Do Big Studios in 2025. Roblox temporarily removed the character after Mementum objected, but negotiations failed and Spyder sued; Mementum later filed trademark counterclaims. A trial is currently scheduled for 29 November 2027, while the central issue is whether AI-generated material can receive copyright protection through human authorship.
