Apple sues OpenAI trade secrets
Apple and OpenAI Are Partners. Apple Just Sued OpenAI for Trade Secret Theft. Here Is What It Means for You
Apple and OpenAI are business partners. ChatGPT is built into the iPhone.
On Friday, July 10, Apple sued OpenAI for stealing its trade secrets. That is not a typo. Two of the biggest names in technology are now partners and courtroom opponents at the same time.
Before the headlines run away with it, one thing matters most. This is a lawsuit. Everything in it is an allegation, not a proven fact.
| THE ROBIUS VERDICT: This is a serious case with serious names. But it is a set of allegations, not a court’s findings. Read it that way. Apple filed suit on Friday in a California federal court. It accuses OpenAI, its hardware unit io Products, and two former Apple employees of a coordinated effort to steal trade secrets for OpenAI’s coming hardware device. OpenAI denies it and says it has no interest in other companies’ secrets. Nobody has been found liable. What is clear so far is that two partners are now fighting in public, which tells you how high the stakes in AI hardware have become. |
What Apple Actually Filed
Apple filed the suit on Friday in the US District Court for the Northern District of California. It alleges trade secret theft and breach of contract.
There are several defendants. OpenAI is one. So is its hardware unit, io Products. So are two former Apple employees. The first is Tang Tan, now OpenAI’s chief hardware officer. He spent about 24 years at Apple, rising to vice president of product design for the iPhone and Apple Watch, before leaving in early 2024 to co-found io with Jony Ive. The second is Chang Liu, a senior electrical engineer who spent eight years at Apple and joined OpenAI in January this year.
The headline claim is blunt. Apple says the theft ran, in the filing’s words, “at every level” of OpenAI, from technical staff up to its chief hardware officer. Apple also notes that more than 400 of its former employees now work at OpenAI. It is not suing over the hiring itself. One more precision worth having: the filing says the companies’ ChatGPT partnership agreement is not at issue in this case. The fight is about hardware secrets, not the existing deal.
What Apple Alleges
The specific claims are detailed, and all of them come from Apple’s filing. None has been tested in court.
Apple alleges that Tan asked Apple staff interviewing at OpenAI to bring real hardware components to their interviews, for show-and-tell sessions. It says he used Apple’s internal project codenames to draw out more detail. It claims he coached departing Apple employees on how to slip past the company’s exit security checks, circulating an internal Apple offboarding document to do it. And it says he emailed himself information about Apple’s suppliers before leaving his own role.
The claims against Liu are just as pointed. Apple alleges he kept his work laptop after leaving, exploited an authentication flaw to reach Apple’s internal network storage, and downloaded dozens of confidential files covering unreleased products and technical specifications. The filing quotes a message it says Liu sent a former colleague about the exploit: “LOL, I found out I can access the [network storage], so funny.” Apple further claims that OpenAI used a proprietary Apple metal-finishing technique with a manufacturing partner, after misleading that partner into believing Apple had approved it.
What OpenAI Says
OpenAI rejects the accusations. In its statement, the company said it has “no interest in other companies’ trade secrets” and is focused on building its own technology. Remember that a denial carries the same weight as an accusation at this stage. Both are claims, and neither is a finding.
Two names are notably absent from the defendant list. OpenAI’s chief executive, Sam Altman, is not named as a defendant. Former Apple designer Jony Ive, whose startup OpenAI bought, is not named at all, and the filing does not accuse him of wrongdoing. And the tension runs both ways. Reports earlier this year said OpenAI had itself weighed suing Apple first, over how their partnership played out.
How the Dispute Surfaced
Apple says it first raised concerns with OpenAI in February, after it began to suspect its technology was appearing in OpenAI’s work. According to the filing, OpenAI never responded. That silence, Apple says, pushed it to investigate further, and it describes what it found as only the beginning of what it believes happened.
The method is worth noting, because it carries a lesson. Like many large companies, Apple built its case by examining activity on company-owned devices and reviewing its server logs. So here is the quiet takeaway for anyone changing jobs. The laptop, the accounts, and the record of what you did on them belong to your employer. That trail does not disappear when you leave.
Why These Two Are Even Fighting
The backdrop is a partnership going sour. In 2024, Apple integrated ChatGPT into its software, in a marquee deal that put OpenAI’s technology on hundreds of millions of iPhones.
Then OpenAI moved into hardware. Last year it bought Jony Ive’s device startup, io, in a deal valued at roughly $6.5 billion, to build its own AI gadget. That put the two on a collision course. Apple makes devices. OpenAI now wants to as well.
Relations have cooled since. Apple announced in June that its revamped Siri, arriving this fall, will run on Google’s Gemini rather than OpenAI’s models. Meanwhile, OpenAI’s first hardware device is expected sometime this year. A lawsuit like this one could slow it down, and it lands at an awkward moment for OpenAI, which is preparing for one of the most anticipated stock market listings in history. Legal clouds and IPOs mix badly.
The Case at a Glance
| Item | Where it stands |

| Claims | Trade secret theft and breach of contract |
| Defendants | OpenAI, io Products, Tang Tan, Chang Liu |
| Not named as defendants | Sam Altman, Jony Ive |
| OpenAI’s position | Denies it, says no interest in others’ secrets |
| Status | Allegations, unproven; Apple seeks an injunction, damages, and the return of its materials |
What This Means in the UAE
The most direct link is in your pocket. ChatGPT is integrated into Apple’s software on the iPhones that millions of UAE residents use every day. A fight between the two companies behind that feature is worth following, not for the drama, but because it can shape what your phone does next.
There is a product angle too. OpenAI’s hardware device is coming, possibly this year, and a legal cloud like this can slow or reshape a launch. If you were thinking of buying the first OpenAI gadget, that uncertainty is now part of the decision.
And there is the lesson Robius keeps repeating. AI partnerships are not permanent. The Apple and OpenAI deal looked rock solid in 2024. Two years later, they are in court, and Siri is moving to a rival’s models. If your business or your household leans on a single AI ecosystem, keep the ability to switch. Today’s partners can become tomorrow’s rivals.
The Bottom Line
This is a high-stakes case, and the filing is dramatic. But drama in a complaint is not the same as proof. Apple has made its accusations. OpenAI denies them. No court has decided anything yet.
So treat the named individuals as accused, not guilty, and watch how the case moves through the system. One more Robius habit applies here. When a story is this big and this fast, the first version is rarely the final one. Check the date, and check back.
