EU Court Rules 'OPENAI' Is Descriptive, Blocks Trademark on Software and Cloud Services
The EU General Court in Luxembourg has ruled against OpenAI in a trademark dispute, upholding the European Union Intellectual Property Office’s earlier decision to reject the “OPENAI” word mark for software, cloud computing services, and identity verification.
The court found the term purely descriptive. “Open” is understood by the relevant public as meaning freely accessible. Combined with “AI” — short for artificial intelligence — the compound signals products based on openly accessible AI technology. The linguistic combination is not unusual in English, the court held. That descriptiveness means the mark lacks the distinctiveness required for trademark protection under EU law.
OpenAI’s Arguments, Rejected
OpenAI contested on three grounds. First, “open” has multiple meanings and “OPENAI” functions as a coined compound without a fixed definition. Second, the EUIPO had previously registered comparable marks. Third, OpenAI holds successful trademark registrations in more than 30 countries including the UK and Singapore.
The court rejected all three. A term does not need to be currently used descriptively to be ineligible — it is sufficient that it could be used descriptively in the future. Prior EUIPO registrations of comparable marks are not binding precedent. And trademark grants in other jurisdictions carry no weight under EU trademark law.
What It Means in Practice
The ruling only applies to the EU. OpenAI retains registrations elsewhere. But the practical effect is real: competitors can use the words “open AI” to describe freely accessible AI products in European markets without automatically infringing.
OpenAI can still appeal to the European Court of Justice. The EUIPO also noted separately that it would examine whether the mark has acquired distinctiveness through long use in the EU market — a secondary path to registration if OpenAI can demonstrate consumer recognition.
The ruling lands at an awkward moment. OpenAI’s flagship models are proprietary and the company’s open-weights strategy lags well behind Meta, Google, DeepSeek, and Alibaba. The court’s core finding — that “OPENAI” means freely accessible artificial intelligence — is precisely the gap critics have flagged between the company’s name and its current business model.
