rotten to its core by its illegal reliance on misappropriated trade secrets
In the contested terrain between Silicon Valley's old guard and its AI insurgents, Apple has filed a federal lawsuit accusing OpenAI of building its hardware ambitions on a foundation of stolen secrets. Two former Apple veterans — one a 24-year company man who rose to vice president — are alleged to have carried proprietary blueprints, supplier relationships, and internal codenames out the door and into the hands of a direct competitor. The suit arrives not as a surprise but as a culmination: what began as a partnership between the two companies has curdled into open legal warfare, raising the deeper question of who holds the right to shape the next era of human-device relationships.
- Apple's 41-page federal complaint accuses OpenAI and two former employees of orchestrating a coordinated, methodical theft of unreleased hardware specs, supplier data, and proprietary terminology — not a casual leak, but an alleged operation.
- The alleged scheme reaches inside Apple's own walls: Chang Liu is accused of instructing a current Apple employee on how to evade internal security teams while copying confidential files.
- Tang Tan, a 24-year Apple veteran who oversaw iPhone and Apple Watch development, is accused of using Apple's internal codenames during OpenAI recruiting and directing candidates to physically bring Apple hardware components into interview rooms.
- OpenAI's $6.4 billion acquisition of Jony Ive's io Products — the centerpiece of its smartphone-displacing hardware strategy — is now legally entangled, with Apple alleging the entire initiative rests on misappropriated intellectual property.
- The lawsuit marks a complete rupture: Apple and OpenAI were once in partnership talks, but Apple pivoted to Google for AI in January, and the filing now transforms a dissolved collaboration into a federal adversarial proceeding.
- With Apple navigating a CEO transition and OpenAI preparing for an IPO amid fierce AI competition, both companies face this confrontation at a moment of maximum strategic vulnerability.
Apple has filed a federal lawsuit accusing OpenAI of systematically stealing its most closely guarded secrets through two former employees now working at the AI company. The 41-page complaint names Tang Tan, OpenAI's chief hardware officer, and Chang Liu, a technical staff member, as central figures in what Apple describes as a coordinated theft operation — one that extends to OpenAI itself and io Products, the design firm OpenAI acquired for $6.4 billion last year.
Tan spent roughly 24 years at Apple, rising to vice president over iPhone and Apple Watch development before departing in 2024. Apple alleges he left with far more than institutional knowledge: he is accused of using Apple's internal codenames during OpenAI's recruiting process, encouraging interviewees to share confidential information, and directing candidates to physically bring Apple hardware components into interview rooms. Liu, meanwhile, is accused of downloading dozens of confidential hardware files and instructing an Apple employee still inside the company on how to circumvent its security teams — a detail that suggests deliberate coordination rather than opportunism.
The lawsuit lands at a moment of sharp strategic divergence. Apple and OpenAI were once in discussions about integrating ChatGPT into Apple's ecosystem, but that relationship fractured. In January, Apple announced it was turning to Google for AI instead. Now the rupture is complete and adversarial.
At the center of the dispute is OpenAI's hardware ambition — a push to build AI devices capable of displacing the smartphone, led in part by Apple's legendary former design chief Jony Ive. Apple's lawsuit suggests that this entire strategy, the one CEO Sam Altman has staked OpenAI's future on, may rest on stolen intellectual property. OpenAI denied the allegations flatly. Apple, a company whose secrecy is industry legend, chose to air them in federal court — a signal of how seriously it views the breach.
The timing sharpens the stakes for both sides. Apple is preparing a leadership transition as Tim Cook hands control to John Ternus in September. OpenAI is moving toward an IPO while facing intensifying competition from Anthropic and Google. What began as a legal filing is also a declaration: a fight over who holds the right to build the next generation of devices that mediate human life.
Apple has filed a lawsuit in federal court accusing OpenAI of systematically stealing its most closely guarded secrets—blueprints for unreleased devices, technical specifications, supplier relationships, and proprietary terminology—through two former Apple employees now working at the AI company. The 41-page complaint names Tang Tan, OpenAI's chief hardware officer, and Chang Liu, a member of OpenAI's technical staff, as the architects of what Apple describes as a coordinated theft operation that extends to OpenAI itself and io Products, the hardware design firm that OpenAI acquired for $6.4 billion last year.
Tan spent roughly 24 years at Apple, rising from product designer to vice president overseeing iPhone and Apple Watch development before departing in 2024 to join io Products. According to the lawsuit, he did not leave quietly. Apple alleges that Tan systematically stole confidential information, used Apple's internal codenames during OpenAI's recruiting process, encouraged interviewers to share secrets from the iPhone maker, and directed candidates to physically bring Apple hardware components into interview rooms. The specificity of these allegations—the deliberate use of Apple's own language, the orchestrated recruitment strategy—suggests a pattern rather than casual knowledge transfer.
Chang Liu, meanwhile, is accused of downloading dozens of confidential hardware files containing technical specifications, engineering presentations, and proprietary data for products that have not yet reached consumers. The lawsuit further alleges that Liu instructed an Apple employee on how to circumvent the company's security teams when copying files—a detail that suggests the theft was not opportunistic but methodical, involving coordination with someone still inside Apple's walls. OpenAI, as an organization, is accused of weaponizing this stolen knowledge, using misappropriated information about Apple's supplier relationships and proprietary terminology to approach Apple's manufacturing partners directly.
The lawsuit arrives at a moment of profound strategic divergence between the two companies. Apple and OpenAI were once in partnership discussions about integrating ChatGPT into Apple's software ecosystem and bringing Siri into OpenAI's products. That collaboration dissolved. In January, Apple announced it was turning to Google instead for its artificial intelligence initiatives, a public signal that the relationship had fractured. Now, with this lawsuit, the rupture is complete and adversarial.
OpenAI's hardware ambitions are the beating heart of this dispute. The company has been building devices designed to run ChatGPT independently, part of a broader strategy to own the physical products that deliver its technology rather than remain dependent on hardware giants. OpenAI's CEO Sam Altman has been explicit about his vision: a new class of AI device that displaces the smartphone as the primary consumer technology. Jony Ive, Apple's legendary design chief, joined that mission and cofounded io Products, which OpenAI then acquired. Apple's lawsuit suggests that this entire hardware strategy—the one Altman has staked OpenAI's future on—rests on stolen intellectual property.
In its statement to Fortune, OpenAI denied the allegations flatly, saying it has no interest in other companies' trade secrets and remains focused on building innovative technology. Apple, in turn, emphasized its commitment to protecting the intellectual property its teams develop. The company's reputation for secrecy is legendary in the industry; the fact that it is willing to air these allegations publicly, in a federal court filing, underscores how seriously it views the breach.
The timing is significant for both organizations. Apple is in the midst of a leadership transition, with CEO Tim Cook preparing to hand control to John Ternus in September. OpenAI is preparing for an initial public offering while facing intensifying competition from other AI makers like Anthropic and Google. The lawsuit, then, is not merely a legal matter—it is a statement about the future of the AI hardware market, about who owns the right to build the next generation of consumer devices, and about the price of poaching talent and knowledge from one of the world's most secretive companies.

The Hearth Conversation Another angle on the story
What made Apple decide to go public with this? They're famous for keeping everything quiet.
Because the alleged theft goes to the heart of their competitive advantage. If OpenAI is building hardware on stolen iPhone and Watch blueprints, Apple isn't just losing a business partner—it's losing control of its own future.
But couldn't they have handled this privately, with a settlement?
Maybe. But OpenAI is about to go public and raise enormous capital. Apple may have decided that silence now means legitimizing the theft later. This lawsuit is a warning to the market.
What about Jony Ive? He's not named in the lawsuit, but he's the one who left Apple for OpenAI.
That's the interesting part. Ive is protected, perhaps because he didn't work at Apple when the alleged theft happened, or because Apple is being strategic about who it accuses. But his presence at io Products—the company OpenAI bought for $6.4 billion—is the whole point. Apple is saying the hardware strategy itself is tainted.
So this is really about the smartphone replacement market?
Exactly. Altman wants AI devices to replace phones. Apple wants to keep selling phones. If OpenAI's devices work because they're built on stolen Apple designs, then Apple loses twice—it loses the market and it loses the credit for innovation.
What happens next?
That depends on what evidence Apple can produce. If the downloads and the recruiting conversations are documented, OpenAI faces serious liability. If not, this becomes a long legal fight that both companies would rather avoid.
