US judge dismisses Musk’s xAI trade secret lawsuit against OpenAI

A United States federal judge has dismissed a lawsuit by Elon Musk’s artificial intelligence company xAI that accused rival Sam Altman’s OpenAI of stealing trade secrets for chatbots.

US District Judge Rita Lin in San Francisco said on Monday that xAI failed to show that OpenAI induced former xAI senior engineer Xuechen Li to divulge confidential information related to its Grok chatbot, or that OpenAI engineers knew Li might have disclosed any.

Lin dismissed the lawsuit with prejudice, saying it would be “futile” to continue. She dismissed an earlier version in February. The lawsuit originally filed last September focused on broader alleged misappropriation of confidential information, including source code, by xAI employees who left for jobs at OpenAI.

Monday’s decision is Musk’s second legal loss against OpenAI in four weeks.

On May 18, a federal jury ruled against Musk , the world’s richest person, in his $150bn lawsuit accusing OpenAI and Altman of “stealing a charity” by betraying the company’s original mission as a nonprofit to enrich themselves.

The xAI business is part of Musk’s rocket, satellite and AI company SpaceX .

Lawyers for xAI did not immediately respond to requests for comment. OpenAI and its lawyers did not immediately respond to similar requests.

The amended complaint focused on a presentation that Li gave while OpenAI was recruiting him.
