OpenAI learned the hard way that Cameo trademarked the word ‘cameo’

OpenAI's Sora app features a deepfake tool called Cameo, but faces legal troubles after U.S. District Judge Eumi K. Lee imposed a temporary restraining order against the use of the trademarked term 'cameo' by Cameo, Inc. The order, effective November 21, 2025, will last until a hearing on December 19, 2025, with Cameo's CEO seeking a permanent cessation of its usage.

  • U.S. District Judge Eumi K. Lee granted a temporary restraining order against OpenAI's use of the term.
  • The order is temporary until a hearing on December 19, 2025, aimed at determining the future of the trademark usage.
