Cameo Sues OpenAI Over “Cameo” Trademark Use in Sora App

Cameo has filed a trademark infringement lawsuit against OpenAI in the Northern District of California. Cameo alleges that OpenAI’s Sora app launched a new feature, also called “Cameo,” that allows users to create and share realistic AI-generated likenesses of themselves and celebrities in personalized videos.

According to the complaint, OpenAI’s use of the “Cameo” name is likely to cause consumer confusion and dilute Cameo’s well-known brand, which has become synonymous with authentic, personalized celebrity videos since its launch in 2017.

Cameo claims OpenAI intentionally adopted the mark to traffic on its goodwill, mislead users, and threaten the company’s existence, citing evidence of consumer confusion and third-party misuse of the mark. The suit asserts federal and state claims for trademark infringement, dilution, and unfair competition, seeking injunctive relief and damages.
