rotten to its core by its illegal reliance on misappropriated trade secrets
For the first time in its fifty-year history, Apple has turned to the courts against a partner, filing suit in California against OpenAI and alleging that the AI startup orchestrated a deliberate campaign to extract trade secrets through the movement of more than 400 former employees. The case names specific executives — including OpenAI's chief hardware officer, once a steward of the iPhone and Apple Watch — and raises questions that reach far beyond two companies: in an era when talent flows freely and knowledge travels with it, where does collaboration end and theft begin? The lawsuit arrives on the eve of OpenAI's anticipated public offering, casting a long shadow over what had once been heralded as a landmark partnership between the world's most valuable hardware maker and the pioneer of modern artificial intelligence.
- Apple, which has never sued a close partner in five decades, crossed that threshold on July 10th — a signal that the breach it perceives is existential, not merely competitive.
- The company accuses OpenAI of coaching departing employees to stay through their notice periods, preserving system access long enough to download confidential files on unreleased products, engineering specs, and proprietary designs.
- Two individuals are named directly: Tang Tan, now OpenAI's chief hardware officer, and Chang Liu, a former iPhone engineer alleged to have downloaded dozens of confidential files in the weeks before leaving Apple.
- The defection of Jony Ive, Apple's legendary design visionary, to OpenAI — along with the executive leading Apple's smart glasses effort — has sharpened the sense that a coordinated talent exodus is reshaping the hardware race.
- Apple sought a private resolution months ago and received no response; it now demands OpenAI destroy all stolen materials and redesign upcoming products before its anticipated IPO, and is seeking a jury trial.
For fifty years, Apple never sued a partner. On July 10th, that changed. The company filed suit in the Northern District of California against OpenAI — the same startup whose CEO sat in the audience at Apple's developer conference two years ago when the two firms announced a collaboration on AI features for iPhones and other devices. Craig Federighi had called OpenAI the "pioneer and market leader" in AI. Apple now calls its hardware business "rotten to its core."
The lawsuit centers on two named individuals. Tang Tan, once Apple's head of product design overseeing the iPhone, Apple Watch, and AirPods, left in 2024 and eventually became OpenAI's chief hardware officer. Chang Liu, a former iPhone hardware engineer, joined OpenAI in January and is accused of downloading dozens of confidential files — engineering presentations, technical specifications, proprietary project data — over several weeks while still employed at Apple. Beyond these two, Apple notes that more than 400 former Apple employees now work at OpenAI, a figure it frames not as ordinary attrition but as evidence of a coordinated pattern.
The most pointed allegation concerns method. Apple claims OpenAI actively coached departing employees — advising them not to disclose their next employer and instructing them how to avoid the immediate removal that would cut off system access. By guiding workers through a standard two-week notice period, Apple argues, OpenAI preserved a window during which confidential materials could be accessed and taken. Apple calls this a deliberate strategy to extract proprietary knowledge while maintaining plausible deniability.
The backdrop has grown more charged over the past year. OpenAI acquired the design firm of Jony Ive — Apple's legendary design visionary — for $6.5 billion, bringing Ive and fellow Apple design veteran Evans Hankey into the fold. The executive leading Apple's smart glasses effort departed to OpenAI just last month. OpenAI has never publicly described what hardware it is building, speaking only of a new way to interact with AI beyond traditional interfaces. Apple's lawsuit implies that whatever it is, it was built on stolen knowledge.
Apple says it sought a private resolution months ago and received no reply. It now demands that OpenAI cease the alleged practices, destroy all proprietary materials, and redesign any products that incorporate Apple's technology — all ahead of OpenAI's anticipated IPO. The company is seeking a jury trial. Bloomberg has separately reported that OpenAI was weighing its own legal action against Apple, alleging the partnership failed to deliver promised benefits. What began as a celebrated alliance between two technology giants has become a high-stakes legal confrontation that may set the terms for how the industry handles talent, intellectual property, and the boundaries of competition for years to come.
In fifty years of existence, Apple has never sued a close partner. On Friday, July 10th, that changed. The company filed a lawsuit against OpenAI, the artificial intelligence startup whose CEO sat in the audience at Apple's developer conference two years earlier, when the two firms announced they would work together on AI features for iPhones and other devices. That partnership had seemed promising. Craig Federighi, Apple's software chief, had called OpenAI the "pioneer and market leader" in AI. Now Apple accuses the startup of orchestrating a systematic campaign to steal its trade secrets—designs, engineering specifications, confidential product information—through a coordinated effort involving departing employees and executives.
The lawsuit, filed in the Northern District of California, names two individuals specifically. Tang Tan, now OpenAI's chief hardware officer, previously led product design at Apple, overseeing development of the iPhone, Apple Watch, and AirPods. He left Apple in 2024 to co-found an AI devices startup before joining OpenAI. Chang Liu, a former iPhone hardware engineer, joined OpenAI in January and is accused of downloading dozens of confidential files about unreleased products, including engineering presentations, technical specifications, and proprietary project data. Apple claims the theft occurred over several weeks while Liu was developing hardware for OpenAI. The company also notes that more than 400 former Apple employees now work at OpenAI—a number Apple describes as evidence of a broader pattern rather than isolated departures.
According to the lawsuit, OpenAI encouraged these employees to share information during job interviews and actively coached departing workers on how to handle their exits. The startup allegedly advised employees not to disclose their next employer and instructed them on how to avoid what Apple calls the "dreaded walk out"—the immediate removal that would cut off access to company systems. Instead, OpenAI's guidance allowed employees to remain for a standard two-week notice period, during which they could continue accessing Apple's confidential materials. Apple describes this as a deliberate strategy to extract proprietary information while maintaining plausible deniability.
Tensions between the companies have escalated over the past year, particularly after OpenAI enlisted Jony Ive, Apple's legendary design visionary, to help develop devices. Ive and Evans Hankey, another Apple design veteran, joined OpenAI after the startup acquired their company for $6.5 billion. The top executive leading Apple's smart glasses effort also departed to OpenAI last month. Meanwhile, OpenAI has never publicly detailed what hardware device it is building, describing it only as an effort to create a new way to interact with AI beyond "traditional products and interfaces." Apple's lawsuit suggests that whatever OpenAI is developing rests on stolen knowledge.
Apple says it attempted to resolve the dispute out of court months ago, asking OpenAI to cease its efforts and destroy any proprietary materials. The company received no response. In the lawsuit, Apple demands that OpenAI stop the alleged practices, destroy all stolen materials, and redesign upcoming products to exclude any of Apple's technology. The company is seeking a jury trial. Apple's statement in the filing is blunt: "At every level, from members of its technical staff to its chief hardware officer, and in coordination with business partners, OpenAI has been stealing Apple's trade secrets and confidential information." The company calls its findings "the tip of the iceberg," noting it has limited visibility into what happens inside OpenAI's operations. It describes the startup's hardware business as "rotten to its core by its illegal reliance on misappropriated trade secrets."
The timing is significant. OpenAI is preparing for an initial public offering in the coming months, and this lawsuit arrives as the company faces scrutiny over its business practices and governance. Bloomberg has also reported that OpenAI was considering its own legal action against Apple, claiming the partnership failed to deliver expected benefits and considering a breach of contract notice. What began as a promising collaboration between two technology giants has devolved into a high-stakes legal battle that will likely define how AI companies and hardware makers navigate talent, intellectual property, and the boundaries of competitive behavior in the years ahead.

The Hearth Conversation Another angle on the story
Why would Apple wait until now to sue? They've known about these departures for months.
Apple says it tried to settle quietly first. They sent OpenAI a cease-and-desist months ago and got no response. That's when they decided to go public with the lawsuit.
Four hundred former Apple employees at OpenAI—that's a staggering number. How does that even happen?
It's a combination of things. OpenAI is building hardware, which is Apple's core strength. The salaries and equity packages are enormous. And according to Apple, OpenAI actively recruited people and coached them on how to leave without triggering immediate lockouts.
The lawsuit mentions that OpenAI advised people on avoiding the "dreaded walk out." What does that mean?
When someone leaves Apple, they're usually escorted out immediately. But if you give two weeks' notice, you can stay and keep accessing systems. Apple claims OpenAI told people to do exactly that—stay those two weeks and download everything they could.
So this is about more than just hiring talent. It's about systematic extraction.
Exactly. Apple isn't just upset that people left. They're alleging a coordinated campaign to steal specific information about unreleased products. The lawsuit names individuals who allegedly downloaded dozens of confidential files.
What does OpenAI actually want to build?
They've never said exactly. They describe it as a new way to interact with AI beyond traditional interfaces. But they're being deliberately vague, which is interesting given Apple's accusations.
And this is happening right before OpenAI's IPO?
Yes. The timing is brutal for OpenAI. Going public with this lawsuit hanging over them could complicate their offering significantly.
