Apple Asked a Judge to Freeze OpenAI Out of Its Trade Secrets. The io Device Now Runs on a Court Clock.

On Monday, Apple asked a federal judge in the Northern District of California for a preliminary injunction that would bar OpenAI, its hardware subsidiary io Products, and two former Apple employees from acquiring, accessing, using, or disclosing what Apple says are its trade secrets. Apple filed a second motion the same day asking for expedited discovery: document production covering the defendants' alleged access to Apple confidential material, plus depositions of four people, two of whom are current OpenAI employees. The hearing is set for October 1.

This is the escalation of the suit Apple filed on July 10 against OpenAI, io Products, former senior system electrical engineer Chang Liu, and former vice president of product design Tang Yew Tan, the executive who ran product design for the iPhone and Apple Watch before joining Jony Ive's hardware effort. A complaint is an accusation. A preliminary injunction motion is a demand that the court act before trial, and to get one Apple has to show it is likely to win and that waiting causes irreparable harm. Apple just told the court that every week io keeps working is a week of damage that money cannot fix.

The Numbers

The Discovery Motion Is the Weapon

Most coverage led with the injunction. I think the expedited discovery motion is the sharper instrument. An injunction phrased as "do not use Apple's trade secrets" is genuinely hard to police. OpenAI will say it is not using any, work inside io continues, and enforcement collapses into an argument about what any given CAD decision was derived from. Discovery is different. Apple is asking the court to order production of documents showing exactly what the defendants accessed, and to put four people under oath months before a trial would normally reach them: Liu, Tan, OpenAI employee Yu-Ting Peng, and a fourth OpenAI employee, unnamed in public filings, who previously worked at Apple.

Depositions taken in August and September feed directly into the October 1 hearing. If any of the four gives Apple a usable admission, the injunction argument writes itself. If none do, Apple still walks away with a map of io's early design process, which is exactly the thing OpenAI paid roughly $6.5 billion to keep private when it bought Ive's startup. There is no symmetric downside for Apple. Its secrets are already the subject of the case; io's are not, yet.

Apple also signaled in this week's filings that the defendant list may not be done growing, saying additional former employees may have taken confidential data on their way out. The July complaint already described a scheme it said operated "at every level": confidential hardware designs, CAD files, manufacturing processes, and supply chain strategy, with recruiting used as the extraction mechanism. Reporting on the complaint read like a spy novel, with allegations of pre-departure downloads and coordinated timing. None of that is proven. All of it is now headed for sworn testimony on an accelerated clock.

OpenAI's Answer Is Total Denial

OpenAI did not hedge. Its public response: the motion is "based on false information and completely unnecessary because we do not have, nor want, any of their trade secrets." That is the strongest available position and also the most brittle one. A company that argued its device work is independently derived could lose a document fight and survive it. A company that says it holds nothing at all has staked its credibility on discovery coming back empty. If a single Apple-marked file surfaces on an io system, the categorical denial becomes Exhibit A on irreparable harm.

The denial also does nothing to slow the process. Apple does not need to prove theft to win expedited discovery; it needs to convince a judge that the question is urgent enough to answer early. The device program's own momentum works against OpenAI here. The more real the io hardware becomes, the easier it is for Apple to argue that any misappropriated process knowledge is being baked into tooling and supplier contracts right now, which is the definition of harm an injunction exists to stop.

Why Trade Secrets Are the Only Lever Apple Has

Step back and the strategy is legible. California will not enforce non-compete agreements, so Apple cannot stop its engineers from walking to io, and dozens have. Poaching is legal. Salary competition is legal. What remains actionable is the narrow claim that specific confidential material crossed the street with them. Trade secret law is the last fence around institutional knowledge in California, and Apple is now testing how much weight that fence can bear when the departing team is building the first credible attempt at a post-iPhone device category.

That is why this case matters beyond Cupertino. Every frontier lab is staffed with people who used to work somewhere that considers its methods confidential, and the talent velocity of this industry has been treated as a feature. A ruling that pre-trial injunctions and expedited depositions are available whenever a rival hires your hardware team would change the price of every senior hire in the valley. A ruling the other way confirms that once employees clear the door, only the most literal file-copying evidence counts.

Two Tracks: Open at the Model Layer, Scorched Earth at the Device Layer

The part I keep coming back to is how cleanly this splits from Apple's model strategy. This spring Apple rebuilt Siri on Gemini and opened iPhone assistant extensions to Claude, ending ChatGPT's exclusivity and treating frontier models as swappable suppliers. At the software layer, Apple decided models are commodities and peace is cheap. At the hardware layer, it is spending its credibility on the most aggressive litigation posture available against the one lab building a device intended to make the iPhone optional. The two moves are the same thesis: the model is not the moat, the object in your pocket is.

For OpenAI the timing is unhelpful in a specific way. The io device does not exist as a product yet; analysts expect AI-native hardware that leans away from the app-and-screen model, on a timeline nobody outside the company can verify. What the injunction motion does, regardless of outcome, is attach a public court calendar to a private hardware roadmap. Suppliers, prospective partners, and the people io is still recruiting can now read a docket instead of a press release. Litigation as signal jamming is an old Apple play; it ran versions of it against Samsung and Masimo. This is the first time the target is a lab it also depends on as a Siri-era partner turned rival.

Our Take

Preliminary injunctions in trade secret cases are hard to get, and judges are especially reluctant when the requested order would shadow an entire product program rather than a named document set. On the public record so far, I would not bet on Apple winning the injunction as scoped. The expedited discovery motion is another matter: courts grant narrower versions of these routinely, and even a partial grant puts io engineers under oath this quarter. The most likely outcome is the one that serves Apple anyway, a months-long window where io's design history gets excavated in front of a magistrate while OpenAI tries to ship around it.

Three signposts. First, whether the court grants any part of expedited discovery before the October 1 hearing, because depositions taken in September change what that hearing is. Second, whether Apple amends the complaint to name additional former employees as defendants, which would confirm the widening it previewed this week. Third, whether OpenAI counterclaims or moves the fight to a different venue entirely, because the categorical denial it published is the posture of a company preparing to attack the premise rather than negotiate.
