Apple's former employees stealing Apple's trade secrets for OpenAI's benefit
In the accelerating race to build the physical infrastructure of artificial intelligence, Apple has turned to the courts — filing suit against OpenAI and two former employees it accuses of carrying proprietary hardware knowledge across a threshold it considers inviolable. The complaint, filed in federal court in California, names a former Chief Hardware Officer and an electrical engineer who worked on the iPhone, Apple Watch, and iPod, alleging their move to OpenAI was not merely a career change but a transfer of protected institutional knowledge. At its core, this case asks an ancient question newly sharpened by the AI era: where does a person's expertise end and a company's secrets begin?
- Apple alleges that two former engineers — one a Chief Hardware Officer — carried sensitive product development data out the door and into OpenAI's hardware ambitions.
- The lawsuit accuses OpenAI not just of benefiting from stolen knowledge, but of orchestrating a 'coordinated pattern of misconduct at an institutional level,' raising the stakes far beyond individual wrongdoing.
- OpenAI has been quietly moving toward physical AI devices, and Apple's complaint implies that stolen trade secrets may have compressed what would otherwise have been years of independent development.
- Neither company has commented, but the Northern District of California — the industry's preferred arena for intellectual property battles — will now become the stage for a fight over where talent ends and theft begins.
- The case lands as a warning shot across the AI industry: as software giants pivot to hardware, the legal battles over engineers, designers, and the knowledge they carry will grow fiercer and more consequential.
Apple filed a civil lawsuit in federal court on Friday against OpenAI and two of its former employees, accusing them of stealing proprietary trade secrets to fuel the AI company's push into physical hardware. The complaint names Tang Tan, OpenAI's Chief Hardware Officer, and Chang Liu, a former electrical engineer — both of whom spent years at Apple working on flagship products including the iPhone, Apple Watch, and iPod.
Apple alleges that when the two men departed for OpenAI, they brought with them sensitive knowledge about Apple's product development processes and technology, using it to give OpenAI a competitive edge in building its own AI-powered devices. The suit goes further than targeting individuals, accusing OpenAI itself of orchestrating a 'coordinated pattern of misconduct at an institutional level' — language that signals Apple views the company, not just its former employees, as complicit.
The lawsuit arrives at a charged moment. OpenAI has signaled plans to move beyond software interfaces into physical products, though it has not disclosed what those devices will look like or when they might launch. Apple's complaint implies that stolen information may have accelerated that timeline.
The case will likely turn on what Apple can prove was actually transferred, how it was used, and whether OpenAI's hardware development benefited from specific proprietary knowledge rather than general engineering skill. OpenAI will almost certainly argue its employees relied only on their own expertise. For now, the filing stands as both a legal action and a signal — that as AI companies move from code into hardware, the industry's battles over talent and intellectual property are entering a more complex and contentious phase.
Apple filed a civil lawsuit in federal court on Friday against OpenAI and two of its former employees, accusing them of stealing proprietary trade secrets to accelerate the company's push into AI hardware. The complaint names Tang Tan, OpenAI's Chief Hardware Officer, and Chang Liu, a technical staffer, as the individuals who allegedly transferred sensitive information from their time at Apple to benefit OpenAI's own product development efforts.
According to the lawsuit, Tan spent years at Apple working on some of the company's most iconic products—the iPhone, Apple Watch, and iPod. Liu, a former electrical engineer at Apple, had access to similarly sensitive data about the company's product development processes and technology. The suit alleges that both men brought this knowledge with them when they moved to OpenAI, using it to give the AI company an advantage in developing its own hardware.
Apple's complaint goes beyond naming individuals. The company also accuses OpenAI itself of orchestrating what it describes as a "coordinated pattern of misconduct at an institutional level." The language suggests Apple believes the company, not just its employees, was complicit in acquiring and using the stolen information. "This case is about Apple's former employees stealing Apple's trade secrets for the benefit of OpenAI," the complaint states. "Apple brings this suit to put a stop to it."
The timing of the lawsuit reflects the intensifying competition in artificial intelligence, particularly around hardware. OpenAI has been publicly exploring ways to move beyond traditional computer interfaces, signaling plans to develop physical devices that run its AI software. The company has not yet disclosed what these products will look like or when they might arrive. Apple's suit suggests that OpenAI may have used stolen information to accelerate that timeline.
Neither Apple nor OpenAI offered immediate comment on the filing. The case was brought in the Northern District of California, the federal court that handles much of the tech industry's intellectual property litigation. The lawsuit arrives as the AI sector faces mounting pressure over talent acquisition and the protection of proprietary technology. Major companies are competing fiercely to hire experienced engineers and designers, and disputes over what knowledge those employees can bring to new employers are becoming more common.
The case will likely hinge on what specific information Apple can prove was transferred, how it was used, and whether OpenAI knowingly benefited from trade secrets rather than independently developed technology. Apple will need to demonstrate that the information was genuinely proprietary, that it was kept confidential, and that OpenAI's hardware development would not have progressed as quickly without it. OpenAI will presumably argue that its employees used only their general knowledge and skills, not specific Apple secrets.
For now, the lawsuit stands as a marker of how seriously Apple takes the protection of its hardware design processes, and how willing it is to pursue former employees in court. It also signals that as AI companies move from software into physical products, the legal battles over talent and intellectual property will only grow more complex.

La Conversación del Hearth Otra perspectiva de la historia
Why would OpenAI need to steal Apple's secrets? Couldn't they just hire good engineers and build their own hardware?
They could, but hardware design isn't just about hiring talent. It's about years of accumulated knowledge—how to integrate components, manage thermal issues, optimize for manufacturing at scale. That institutional knowledge is what Apple is protecting.
So this is really about speed. OpenAI wanted to move faster than they could on their own.
Exactly. In the AI race, being first matters enormously. If you can compress years of development into months by using someone else's blueprints and processes, that's a massive competitive advantage.
But how do you prove someone stole something intangible like design knowledge?
That's the hard part. Apple will need to show specific documents, designs, or technical specifications that moved from Apple to OpenAI. General knowledge and skills are fair game; proprietary information is not.
What happens if Apple wins?
They could get damages, an injunction preventing OpenAI from using the information, or both. But the real question is whether OpenAI's hardware is already too far along to stop.
Is this common in tech?
It's becoming more common as companies compete for the same talent pool. The tension between protecting secrets and letting talented people move freely is one of the industry's thorniest problems.
