Apple has filed a blockbuster lawsuit against OpenAI in federal court, accusing the AI company of orchestrating a systematic campaign to steal hardware trade secrets by coaching departing Apple employees to smuggle confidential information and even physical parts out of the company.
The lawsuit, filed in the Northern District of California, marks a dramatic rupture between two companies that were partners as recently as 2024, when ChatGPT was integrated into the iPhone.
The Allegations Are Specific and Damning
This is not a vague intellectual property complaint. Apple’s filing lays out a detailed narrative of what it calls deliberate espionage at every level of OpenAI’s organization, from rank-and-file engineers to the company’s chief hardware officer.
The most striking allegation centers on Tang Tan, OpenAI’s hardware chief and a former Apple vice president. Apple claims Tan directed Apple employees who were interviewing at OpenAI to bring “actual parts” from Apple to interviews for what amounted to show-and-tell sessions. The filing also alleges that OpenAI coached departing Apple employees on how to evade Apple’s security processes when leaving the company.
One specific case involves Chang Liu, a former Apple employee who joined OpenAI. Apple alleges Liu stole an Apple laptop and, while developing hardware for OpenAI, accessed and downloaded dozens of confidential files from Apple’s network, many of them labeled as confidential. If proven, these are not gray-area competitive intelligence moves. They are the kind of allegations that can end careers and trigger criminal referrals.
The Jony Ive Connection
The backstory makes this lawsuit even more loaded. Apple and OpenAI entered their high-profile partnership in 2024 when Siri’s integration with ChatGPT made OpenAI a central part of the iPhone experience. The relationship started to sour after OpenAI announced plans to enter the hardware business, and it fractured entirely when OpenAI acquired IO Products, the startup founded by former Apple design legend Jony Ive, for $6.4 billion.
That acquisition put OpenAI in direct competition with Apple in consumer hardware, and Apple’s lawsuit essentially argues that OpenAI did not just compete fairly. It allegedly built its hardware ambitions on a foundation of stolen Apple intellectual property, using Ive’s former network and former Apple executives to strip-mine confidential designs and engineering processes.
OpenAI’s Response and What It Means
OpenAI responded with a boilerplate denial: “We have no interest in other companies’ trade secrets. We remain focused on building innovative technology that empowers people everywhere.” That phrasing is carefully lawyered, and it will need to be, because Apple’s complaint is built on specific names, specific documents, and specific incidents rather than generalized allegations of competitive harm.
The broader significance extends beyond the two companies. OpenAI has been aggressively hiring from across Big Tech, and if Apple can establish that its hiring pipeline included systematic extraction of trade secrets, the precedent could reshape how the entire AI industry handles talent acquisition. Every major AI lab has been poaching from established hardware and software companies. The question Apple’s lawsuit raises is whether some of that poaching crossed the line from aggressive recruitment into outright theft.
The Legal Road Ahead
Trade secret cases are notoriously difficult to prove because they require showing not just that information was taken but that it was actually used in the defendant’s products. Apple will need to demonstrate a direct line between the allegedly stolen files and OpenAI’s hardware development program. Discovery in this case is likely to be explosive, with internal communications and engineering documents at the center of the fight.
For OpenAI, which is simultaneously navigating a proposed government stake deal, regulatory scrutiny, and its transition to a for-profit structure, this lawsuit adds a significant legal and reputational liability. The company that wants to be America’s AI champion now has to explain why its hardware division allegedly operated like a corporate espionage unit.
