Overview
- U.S. District Judge Eumi Lee granted a preliminary injunction ordering OpenAI to stop using the term “Cameo” for its Sora video tool.
- The court rejected OpenAI’s argument that “cameo” is merely descriptive, finding the usage suggestive and likely to cause consumer confusion.
- An earlier temporary restraining order in November had already prompted OpenAI to rename the feature to “Characters.”
- The order noted concerns that the naming and celebrity-focused promotion could make OpenAI’s tool indistinguishable from Cameo and tether Cameo to AI deepfakes.
- Cameo called the decision a critical victory for its marketplace, while OpenAI said it disagrees that anyone can exclusively own the word and plans to continue its case.
