OpenAI Countersues Apple Over Ex-Employee's Alleged Transfer of Confidential Device Files

OpenAI told a federal court Wednesday that a former employee who left to rejoin Apple transferred more than 100 highly confidential files about an unreleased OpenAI hardware device to his personal accounts, escalating an escalating trade secrets dispute between the two technology giants. The employee, who had previously worked at Apple before joining OpenAI for approximately six months, allegedly sent the materials on June 2, 2026—his final day at the company—and subsequently presented details of OpenAI's AI product plans to Apple's senior leadership, according to the filing in U.S. District Court in San Jose.
