The dispute underscores a rapidly growing issue in AI branding: tech companies choosing product names without conducting proper trademark clearance, resulting in costly legal setbacks. The original report was published by CNBC
What Happened: Cameo vs. OpenAI
According to court filings, Cameo — the well-known platform for personalized celebrity video messages — sued OpenAI in October 2025, alleging trademark infringement after OpenAI introduced a Sora feature named “Cameo.”
On November 24, 2025, U.S. District Judge Eumi K. Lee granted a temporary restraining order, blocking OpenAI from using:
- Cameo
- Kameo
- CameoVideo
- any other confusingly similar name
The judge noted a credible risk of consumer confusion, especially given Cameo’s strong brand recognition in the celebrity-video space.
Cameo CEO Steven Galanis publicly praised the decision, stating that the platform must “protect consumers from confusion” and preserve the integrity of its trademark.
OpenAI responded by arguing that “cameo” is a common English word and should not be monopolized, but this argument is unlikely to hold up under U.S. trademark law — which focuses on use in commerce, not dictionary ownership.
A hearing on whether to convert the temporary order into a permanent injunction is scheduled for December 19, 2025.
Why This Case Matters: Trademark Law in the AI Era
The rise of AI features with branded names increases the risk of trademark conflict. Even more importantly:
👉 Big companies are not exempt from basic trademark rules.
Skipping a clearance search can result in injunctions, lawsuits, forced rebranding, and negative press — even for industry leaders.
Key legal points illustrated by this case:
1. Dictionary words can be legally protected
Trademark protection applies to specific goods/services, not the general meaning of the word.
2. Injunctions are a powerful remedy
A TRO immediately disrupts product launches — extremely costly for fast-moving AI companies.
3. Brand confusion is taken seriously in federal court
If consumers might believe the services are connected, an injunction is likely.
4. AI companies face unique naming risks
Dozens of product launches, rapid iterations, and global exposure increase the odds of infringement.
5. Trademark clearance is mandatory, not optional
Failing to check availability is one of the most expensive mistakes a company can make.

Cameo, as most people know, is the platform where you can pay celebrities to record personalized videos — birthday shoutouts, anniversary messages, even quick promos for small businesses. Recently, OpenAI rolled out a new feature in its Sora video AI platform and named it “Cameo.” Cameo, the company, was not amused. They sued OpenAI, and the dispute escalated quickly.
A judge has now issued an injunction prohibiting OpenAI from using “Cameo” — or anything confusingly similar, such as Kameo, Cameo Video, etc., as the name of any product or feature.
OpenAI’s public response leaned on a common misconception: the idea that trademark law allows companies to “own dictionary words.” This argument tends to resonate with people who don’t understand how trademarks work, but legally, it misses the point entirely.
Trademarks aren’t about owning words in general — they’re about owning words in connection with specific goods or services. Apple doesn’t own the word “apple.” They own Apple for computers, phones, software, and related goods. Amazon doesn’t own the river — they own the mark for their marketplace. And there are hundreds of thousands of trademarks built from dictionary words. Nobody’s free speech is restricted; what’s restricted is using those words as a brand, as a product name, as a service name, as a company name, as a tagline, or in a logo. You can say “I’m loving it” in everyday conversation — you just can’t use it as the slogan for your burger joint.
Now, here’s my take:
I am a huge fan of OpenAI’s products. I use them daily, and their work in AI — especially video AI — is phenomenal. But in this case, they showed a bit of the classic tech-giant arrogance: they launched a product name without checking whether they could legally use it.
The playbook for responsible brands is simple:
1. Check whether you can own the name.
2. If someone else already owns it in your category, pick something else.
3. If you can own it, file your trademark before you announce anything.
4. If you launch first, within minutes dozens of opportunistic applicants will file for the same name hoping to profit from your oversight.
OpenAI skipped step one entirely. And now they’re spending time, money, and attention fighting a dispute that could have been avoided with a basic trademark clearance search.
So while I love what OpenAI is building, I wish they had shown more respect for established IP rights. This was preventable — and now it’s a lesson they’ll never forget.
