Apple Sues OpenAI Over Alleged Trade Secret Theft
2 min readApple has taken its rivalry with OpenAI into a courtroom. On Friday, July 10, 2026, Apple filed a federal lawsuit in Northern California accusing OpenAI of a coordinated effort to steal its hardware trade secrets by recruiting and coaching former Apple employees. The complaint lands as both companies race to define the next generation of AI-powered devices.
The Backdrop: A Talent War Turned Legal Fight
Over the past two years, OpenAI has hired aggressively from Apple’s hardware and on-device AI teams. That hiring accelerated after OpenAI absorbed io Products, the device startup tied to former Apple design chief Jony Ive. Apple says the movement of people was not just competition for talent but a channel for its confidential designs to walk out the door.
What Apple Alleges
The lawsuit names OpenAI Foundation, OpenAI Group PBC, and io Products, along with two former Apple employees. Apple claims the theft happened “at every level, from members of its Technical Staff to its Chief Hardware Officer.” It says Chang Liu, a senior systems electrical engineer of eight years, failed to return a company laptop and used it to download confidential technical documents before leaving for OpenAI.
Apple also points to Tang Tan, a 24-year veteran who served as vice president of product design for the iPhone and Apple Watch. According to the filing, Tan directed job candidates still employed at Apple to bring “actual parts” from Apple to their interviews for show-and-tell sessions that elicited even more confidential information. Apple notes that more than 400 former employees now work at OpenAI.
Why It Matters
The case sharpens a broader tension in the AI industry, where the people who carry hard-won knowledge are also the most valuable recruits. If Apple prevails, it could force AI companies to rethink how they onboard hires from rivals and how they document the ideas those hires bring with them. OpenAI has pushed back firmly, saying it has “no interest in other companies’ trade secrets” and remains focused on building useful technology.
For now, the dispute signals that the fight over AI hardware is moving from the lab to the legal system. Expect a long and closely watched battle with implications for how Silicon Valley hires and competes.
