OpenAI just hit a legal roadblock that could reshape how AI companies approach trademark disputes. A federal judge granted a temporary restraining order Monday blocking the AI giant from using "cameo" or similar terms in its Sora video generation platform, following a lawsuit from celebrity video platform Cameo. The month-long ban highlights growing tensions between established tech brands and AI companies racing to launch new features.
The restraining order landed just as OpenAI was ramping up its Sora video platform, creating an immediate headache for the company's product team. U.S. District Judge Eumi K. Lee's decision on Monday blocks OpenAI from using "cameo," "Kameo," "CameoVideo," or any similar variations across its AI-generated video app.
The legal clash stems from Cameo's October lawsuit, which targeted OpenAI's Sora "Cameo" feature that let users generate digital characters of themselves or others and insert them into AI-created videos. The timing wasn't coincidental - Cameo has built its entire business around personalized celebrity videos since 2017, making the trademark particularly valuable.
"We are gratified by the court's decision, which recognizes the need to protect consumers from the confusion that OpenAI has created by using the Cameo trademark," Cameo CEO Steven Galanis said in a statement to CNBC. His company's swift legal action reflects how established platforms are pushing back against AI companies that might inadvertently step on existing intellectual property.
The dispute reveals a broader challenge facing the AI industry as companies rush to launch consumer-facing features. OpenAI has been particularly aggressive in expanding Sora's capabilities, but this legal speed bump shows how trademark considerations can quickly derail product roadmaps. The company declined to comment on the ruling, suggesting they're likely consulting with legal teams on next steps.
What makes this case particularly interesting is the functional overlap between the two platforms. Cameo's service connects fans with celebrities for personalized video messages, while OpenAI's disputed feature essentially democratizes that concept through AI generation. Judge Lee's decision suggests the court sees genuine potential for consumer confusion between the services.
The temporary nature of the order creates a ticking clock scenario. The restraining order expires December 22, with a crucial hearing scheduled for December 19 to determine whether the ban becomes permanent. That timeline gives just weeks to either negotiate a settlement, rebrand the feature, or prepare arguments for why they should be allowed to keep the name.
