OpenAI Loses Trademark Dispute in EU Court

·2026.07.16 10:31

Key point

The EU court ruled that OpenAI's trademark registration refusal was justified, confirming OpenAI's defeat in the trademark dispute.

Details

OpenAI lost the lawsuit it filed with the European Union General Court seeking to overturn the refusal of its trademark registration. The court ruled that the name 'OPENAI' falls under descriptive terminology lacking distinctiveness in certain software and IT service fields.

The EU Intellectual Property Office (EUIPO) determined that 'Open' means 'freely accessible,' and when combined with 'AI,' it could be interpreted as meaning 'openly available artificial intelligence-based products.' OpenAI argued that the term is a coined term with a unique meaning and presented registration precedents from other countries such as the UK and Singapore as grounds, but the court did not accept this.

This ruling reaffirmed that trademark registrations in other countries are not binding on EU trademark law, and OpenAI may appeal to the European Court of Justice (ECJ) in the future.
