Gemini Data has filed a lawsuit against Google, alleging trademark infringement over the use of the name 'Gemini' for its AI tools. The lawsuit, submitted in federal court in San Francisco, claims Google was aware of Gemini Data's trademark when it rebranded its AI service from Bard to Gemini and chose to proceed regardless. Gemini Data argues that Google's actions constitute unfair competition and have the potential to confuse consumers, as it holds federal trademarks for the name in software. Google attempted to register the name but was denied by the US Patent and Trademark Office due to existing trademarks, including those held by Gemini Data. Additionally, the lawsuit alleges Google tried to acquire the Gemini trademark through a third party after the USPTO's refusal. Google has not yet commented on the lawsuit.
