That OpenAI now employs people who were once entrusted with Apple's trade secrets does not entitle OpenAI to use that information
In the long arc of technological ambition, the line between inspiration and appropriation has always been contested ground. Apple's federal lawsuit against OpenAI, filed in California, accuses the AI company of orchestrating a deliberate campaign to extract confidential hardware secrets through former employees and supplier relationships — even as the two companies remain intertwined business partners. The case arrives at a moment when OpenAI's $6.5 billion acquisition of a hardware venture signals its intent to enter the physical device market Apple has long dominated, raising a question as old as industry itself: where does the free movement of talent end and the theft of institutional knowledge begin.
- Apple alleges that two former senior engineers — one of whom exploited an authentication vulnerability to re-enter internal systems after departure — systematically extracted confidential hardware designs, manufacturing methods, and supplier intelligence on OpenAI's behalf.
- The breach, Apple claims, extends far beyond two individuals: more than 400 former Apple employees now work at OpenAI, and at least one supplier was deceived into sharing a proprietary metal-finishing technique under the false impression that OpenAI had Apple's blessing.
- OpenAI's $6.5 billion acquisition of io Products — the hardware startup co-founded by legendary Apple designer Jony Ive — appears to have been the trigger that transformed months of simmering concern into a federal lawsuit after Apple's February outreach went unanswered.
- The legal confrontation now casts a long shadow over an active commercial partnership: ChatGPT is currently integrated into Apple Intelligence and Siri, meaning two companies litigating trade secret theft are simultaneously dependent on each other's cooperation to deliver consumer AI features.
Apple filed a federal lawsuit in California against OpenAI, io Products, and two former senior engineers, accusing them of orchestrating a coordinated scheme to steal confidential hardware secrets. At the center of the complaint are Chang Liu, a senior systems electrical engineer, and Tang Yew Tan, who once led product design for the iPhone and Apple Watch.
Apple alleges that Liu never returned his work laptop after leaving the company and later exploited an authentication vulnerability to re-access internal systems, downloading dozens of confidential hardware files. Tan is accused of emailing himself sensitive supplier information before his departure and later encouraging job candidates interviewing at OpenAI to bring physical Apple components for informal demonstrations — a practice that apparently caught at least one candidate off guard.
The alleged breach reaches beyond these two individuals. Apple notes that more than 400 of its former employees now work at OpenAI, and claims that OpenAI personnel directly approached Apple suppliers seeking proprietary manufacturing details. At least one supplier shared a specialized metal-finishing technique after being led to believe OpenAI had Apple's authorization.
The lawsuit's timing points directly to OpenAI's $6.5 billion acquisition of io Products, the hardware venture co-founded by Jony Ive, which signaled OpenAI's serious ambitions in consumer devices — territory Apple has long commanded. Apple says it raised concerns with OpenAI in February about information flowing into the hardware division but received no response.
What sharpens the confrontation is that the two companies are not rivals in name only — they are active partners. ChatGPT is integrated into Apple Intelligence and Siri, and iPhone users can subscribe to the service directly through iOS. Apple only recently completed its long-delayed Siri overhaul, a product that now relies on OpenAI's technology. Whether two companies locked in a trade secret dispute can sustain that collaboration remains the defining uncertainty hanging over both.
Apple filed suit against OpenAI on Friday in federal court in California, accusing the ChatGPT maker of orchestrating a scheme to steal its most closely guarded hardware secrets. The complaint names two former Apple engineers—Chang Liu, a senior systems electrical engineer, and Tang Yew Tan, who once led product design for the iPhone and Apple Watch—along with OpenAI itself and io Products, the hardware startup OpenAI acquired last year for $6.5 billion.
The lawsuit alleges a coordinated effort to extract confidential information about hardware designs, manufacturing processes, and supply chain strategy. According to Apple's filing, Liu never returned his work laptop after departing the company and later exploited an authentication vulnerability to regain access to Apple's internal systems, where he downloaded dozens of confidential hardware files. Tan took a different route: Apple claims he emailed himself sensitive information about Apple's suppliers and internal industry reports before his departure, then leveraged that knowledge to accelerate OpenAI's hardware ambitions. The company also alleges that Tan encouraged job candidates interviewing at OpenAI to bring physical Apple components to their interviews for informal demonstrations, with one candidate apparently surprised to learn such items could leave the office.
The scale of the alleged breach extends beyond two individuals. Apple notes that more than 400 former employees now work at OpenAI—a talent pipeline the company says has given OpenAI an unfair advantage in its race to build consumer hardware devices. While Apple acknowledges that former employees naturally carry institutional knowledge from their time at the iPhone maker, the lawsuit argues this does not grant OpenAI permission to weaponize confidential information. The company also alleges that OpenAI personnel directly approached Apple suppliers seeking proprietary manufacturing details, with at least one supplier providing a specialized metal-finishing technique after believing OpenAI had Apple's authorization.
The timing of the lawsuit underscores the stakes. OpenAI's $6.5 billion acquisition of io Products—the hardware venture founded by legendary Apple designer Jony Ive—signaled the company's serious pivot from software into physical devices that could directly compete with Apple's ecosystem. That deal, completed in recent months, appears to have triggered Apple's legal response. In February, Apple says it contacted OpenAI expressing concern about information leakage into the hardware division, but received no response. The complaint suggests tensions had been simmering for months before the lawsuit materialized.
What makes this confrontation particularly sharp is that Apple and OpenAI remain active business partners. Since 2024, Apple has integrated ChatGPT directly into its AI features, allowing Siri to hand off certain user requests to OpenAI's chatbot. iPhone users can subscribe to ChatGPT through iOS settings. Apple only last month completed its long-delayed overhaul of Siri, nearly two years after first announcing plans for a more capable AI assistant—a product that now depends on OpenAI's technology. The lawsuit introduces profound uncertainty into this partnership, raising the question of whether two companies locked in a trade secret dispute over hardware can realistically continue collaborating on consumer AI features. Neither Liu nor Tan responded to requests for comment. Jony Ive, despite founding the hardware company OpenAI acquired, was not named as a defendant.

The Hearth Conversation Another angle on the story
Why would OpenAI need to steal Apple's secrets when it has the resources to build hardware from scratch?
Because hardware is brutally hard. Manufacturing, supply chains, miniaturization—these take years to master. OpenAI wanted to move fast, and hiring 400 Apple veterans gave them a shortcut. But Apple says they went further, extracting the actual blueprints and supplier relationships.
Can you really keep trade secrets secret when you hire hundreds of people who used to work somewhere else?
That's the legal question exactly. Apple isn't saying former employees can't work at OpenAI. It's saying OpenAI crossed a line by encouraging them to bring physical components to interviews and by having executives actively extract confidential files before they left.
How does this affect the Siri-ChatGPT partnership?
That's the real tension. They're suing each other in court while Siri is literally handing user requests to ChatGPT. It's awkward and probably unsustainable. Either they settle, or one of them has to walk away from the partnership.
Is Jony Ive in trouble here?
Not legally—he's not named as a defendant. But his io Products company is. The irony is that Ive, who designed the iPhone, is now on the other side building hardware that could compete with Apple. Apple didn't sue him personally, which suggests they may see him as less culpable than the engineers who allegedly accessed systems after leaving.
What does Apple actually want from this lawsuit?
Damages, probably. But more importantly, they want to slow OpenAI's hardware timeline and expose what information was taken. A trade secret case can force discovery that reveals exactly what OpenAI knows and how they got it.
