Apple Sues OpenAI Over Alleged Trade Secret Theft as Tech Partnership Unravels
Apple has filed a lawsuit against OpenAI, accusing the artificial intelligence company of systematically stealing trade secrets as it attempts to build its own hardware division. The complaint, filed Friday, marks a dramatic fracture in a relationship that once looked like one of the tech industry’s most consequential alliances.
The Core Allegations
At the heart of Apple’s complaint is the claim that OpenAI orchestrated a campaign to poach Apple employees and coax them into handing over confidential material, product designs, and other closely guarded information. Apple says significant evidence has emerged suggesting that individuals now employed by OpenAI “wrongfully took Apple’s secret and confidential information regarding our unreleased technologies, processes, and products.”
The lawsuit names several individuals, including Tang Yew Tan, OpenAI’s chief hardware officer and a former Apple vice-president. Apple alleges that Tan took information about Apple suppliers with him to OpenAI and went further, encouraging job candidates still employed at Apple to bring “actual parts” to their interviews for what the complaint describes as “show and tell” sessions designed to extract still more confidential information.
Another former Apple employee, Chang Liu, who was hired by OpenAI, is accused of leaving Apple with a company laptop. According to the complaint, Liu exploited an authentication bug to breach Apple’s internal network and downloaded “dozens of Apple’s confidential hardware-related files.”
OpenAI spokesperson Drew Pusateri said the company was reviewing the court filing but struck a firm defensive tone. “We have no interest in other companies’ trade secrets,” he said. “We remain focused on building innovative technology that empowers people everywhere.”
A Partnership Turned Sour
The lawsuit represents a striking reversal for two companies that, in 2024, announced a high-profile partnership to integrate OpenAI’s ChatGPT into the operating systems powering iPhones, iPads, and Macs. At the time, the deal was widely interpreted as a mutual win — Apple gaining access to a leading AI model, and OpenAI securing distribution across hundreds of millions of devices.
But the alliance has visibly frayed. Last month, when Apple showcased its revamped Siri voice assistant, the underlying AI component was powered by Google’s Gemini model rather than ChatGPT. That decision signaled a clear strategic pivot by Apple and, in retrospect, foreshadowed the legal escalation now underway.
The Hardware Flashpoint
The tensions trace back further, to OpenAI’s $6.4 billion acquisition last year of io Products, a hardware startup founded by former Apple design chief Jony Ive. The acquisition made plain that OpenAI intended to push beyond software and into physical devices — territory Apple has dominated for decades. Ive’s startup is also named as a defendant in the lawsuit.
In its complaint, Apple did not mince words about what it sees as the foundation of OpenAI’s hardware ambitions. “OpenAI’s nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets,” the company wrote.
For Apple, the protection of trade secrets has long been a foundational corporate principle. An Apple spokesperson emphasized that the company’s teams are “constantly developing breakthrough technologies” and that protecting their work and intellectual property is something Apple takes “very seriously.”
What Apple Is Seeking
Apple is pursuing both financial damages and a court order that would bar OpenAI from possessing or using its trade secrets. The latter remedy, if granted, could have significant implications for OpenAI’s hardware roadmap, potentially forcing the company to prove that its product development is not built on improperly obtained Apple information.
The Broader Context
The lawsuit lands at a moment of intensifying competition across the AI and consumer hardware landscapes. As companies race to embed artificial intelligence into physical devices — from phones to wearables to entirely new form factors — the talent and proprietary knowledge that flow between firms have become a battleground. Apple’s decision to litigate rather than quietly negotiate suggests the company views the alleged conduct as serious enough to warrant a public confrontation with a former partner.
The case also underscores how quickly alliances in the AI sector can shift. A partnership that was once touted as a defining collaboration of the AI era has, in roughly a year, devolved into allegations of corporate espionage. Whether the courts will validate Apple’s claims remains to be seen, but the complaint alone sends a clear message: in the race to build the next generation of AI-powered hardware, Apple intends to defend its territory aggressively.
