On October 29, 2025, the U.S.-based celebrity video customization platform Cameo lodged a lawsuit in a federal court in California. It alleged that the 'Cameo' feature integrated into OpenAI's video - generation app Sora infringed upon its trademark rights. Cameo explained that this particular feature enables users to craft and disseminate virtual avatars via Sora. Such an action, in Cameo's view, has the potential to create confusion among consumers and diminish the value of its brand.

In light of these concerns, Cameo is seeking two main forms of redress from OpenAI. Firstly, it demands monetary compensation to make up for any losses incurred due to the alleged infringement. Secondly, it requests a court - issued injunction to prevent OpenAI from continuing to use the name 'Cameo'.

In response, a spokesperson for OpenAI stated that the company is currently in the process of reviewing the lawsuit. However, they firmly hold the stance that no single entity can claim exclusive ownership over the term 'Cameo', as it is a commonly used word in various contexts.
