By Deepa Seetharaman OAKLAND, California, May 19 (Reuters) - OpenAI Chief Executive Sam Altman beat Elon Musk in federal court on Monday, but the win came at the cost of hearing his former colleagues call him a liar - repeatedly - under oath.

California jury dismissed all charges, finding that Musk missed the three-year statute of limitations to file suit.

A jury dismissed the billionaire’s claims that OpenAI improperly transitioned from a nonprofit to a for-profit entity, saying Musk was too late in filing the suit.

A jury in federal court reached a verdict in Elon Musk's lawsuit against OpenAI after Musk accused the maker of ChatGPT of violating its founding mission as a nonprofit.
