The unreturned laptop: what Apple’s complaint against OpenAI actually alleges

Somewhere, if Apple’s lawyers are right, there is an Apple-issued laptop that never came back. It belongs to a company with a famously theatrical exit-security process, it allegedly retained access to Apple’s corporate network through what the complaint calls a rare authentication bug, and its last known user — Chang Liu, now a senior systems electrical engineer at OpenAI — allegedly texted a colleague within hours of his departure: “I still have another computer.”

That laptop is the load-bearing object in the 41-page complaint Apple filed Friday in the Northern District of California against OpenAI, its io hardware subsidiary, Liu, and OpenAI chief hardware officer Tang Yew Tan, first reported by TechCrunch and since picked over by CNBC, NBC News, and roughly everyone else. The weekend coverage has treated the filing as a corporate spy novel, and the weekend’s Musk–Altman name-calling, with IPO money circling both SpaceXAI and OpenAI, hasn’t helped anyone read it calmly. So let’s read it as what it is: a pleading. Some of it is built to survive a motion to dismiss. Some of it is built for headlines.

Two piles: dated and loud

The allegations against Liu are the dated pile. Per Fortune’s read of the complaint, Apple alleges Liu, an eight-year employee who joined OpenAI in January, failed to return at least one work-issued laptop, skipped his exit interview, and never confirmed he’d returned his devices. It alleges he then exploited “a rare, previously unknown authentication bug” to reach Apple’s network — once, allegedly, using the Apple-issued computer of Yu-Ting “Alyssa” Peng, a colleague still employed at Apple who later joined OpenAI herself — and downloaded dozens of confidential files, including a compilation running over a thousand pages on manufacturing and testing a certain type of circuit board. Apple even has him allegedly narrating the act by text: “LOL, I found out I can access the [network storage], so funny.”

Whether or not any of this happened — Liu has not responded publicly, and these are allegations — that is what a well-pleaded misappropriation claim looks like: a device, a mechanism, named files, quoted messages.

The Tan allegations are one notch looser but still specific. Apple alleges the 24-year Apple veteran, who ran product design for iPhone and Apple Watch before leaving in early 2024 to work with Jony Ive, emailed himself supplier information before departing, seeded interviews with Apple’s confidential project code names to pull details out of candidates, and asked applicants to bring “actual parts,” CAD artifacts, and prototypes to “show and tell” sessions. One candidate allegedly replied: “Didn’t even know we could take those from the office.”

Then there’s the loud pile. The complaint notes that roughly 400 former Apple employees now work at OpenAI — a headcount, not a tort. It says OpenAI circulated Apple’s internal “Need to know” materials coaching departing employees on avoiding the “dreaded walkout,” a genuinely damaging allegation if documents support it, but one attributed to OpenAI generally rather than a named person. And it editorializes, in the way complaints do when they’re also press releases:

“This is the tip of the iceberg… OpenAI’s nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets.”

That sentence, quoted by TechCrunch, proves nothing. It signals something, though: Apple is telling the court the named incidents are samples, and that discovery will show misappropriation “on a scale many times greater than the several instances described below.” That is a promissory note. Discovery is where it gets called.

What Apple actually has to prove

Trade-secret law is narrower than the vibes around it. To win, Apple must establish that specific information qualifies as a trade secret — economically valuable because secret, and subject to reasonable protective measures — and that defendants acquired it by improper means or used it knowing it was taken. Our read: the metal-finishing allegation is the cleanest test case. Apple alleges an OpenAI representative asked an Apple supplier to “carry out a specific trade secret metal-finishing technique for OpenAI, misleading the partner to believe they had Apple’s permission.” A discrete process, a named use, an identifiable supplier who can be deposed. Compare that with “400 ex-Apple employees,” which proves only that Apple trains good engineers.

Crucially, California courts have rejected the “inevitable disclosure” theory — the idea that a departing employee will unavoidably use what’s in their head. Apple can’t win by showing Tan knows how iPhones get made. It has to show taking: the emailed supplier lists, the downloaded circuit-board files, the parts in the interview room. Which is exactly why the complaint is organized around objects.

Why name Tan and Liu personally

Apple could have sued OpenAI alone. Naming the two men changes the discovery posture. Individual defendants’ personal devices and accounts become fair game, and the complaint’s quoted texts suggest Apple already has message threads — presumably from forensics on its own systems — that it can use to justify going after the rest. Personal liability also splits interests: OpenAI’s lawyers answer for the company; Tan and Liu need their own counsel, and their incentives and OpenAI’s will not stay perfectly aligned through depositions. That’s not incidental. It’s leverage, and Apple’s outside firm, Weil Gotshal, knows it.

Worth remembering while reading any of this: Tan and Liu are defendants, not convicts. Neither has answered the complaint yet. OpenAI’s entire public response so far is a statement on X: “We have no interest in other companies’ trade secrets.”

The injunction is the ballgame

Apple isn’t primarily asking for money. Per TechCrunch, it wants OpenAI barred from using or disclosing the material, ordered to return it, and compelled to preserve evidence. If Apple moves for a preliminary injunction and gets even part of it, the practical effect lands on OpenAI’s hardware schedule — the io-derived devices 9to5Mac notes are reportedly in the pipeline, including a smartphone eyed for 2028. An order covering the metal-finishing process or supplier relationships built on allegedly taken data could force requalifying vendors and reworking industrial design mid-development, with subpoenas landing on the shared supply chain both companies depend on. For a company that confidentially filed for an IPO in June, litigation risk of that shape goes straight into the prospectus.

One more date matters. Apple says it emailed OpenAI in February asking what the company was doing to prevent all this, and that OpenAI never responded. Five months of silence, then 41 pages. The laptop, as far as anyone has said publicly, is still out there.
