OpenAI Denies Apple’s Trade-Secret Allegations

OpenAI’s reported September 1, 2026 court response rejects Apple’s allegations that confidential information was misappropriated to support OpenAI’s hardware ambitions. OpenAI says Apple has not shown that trade secrets were stolen, attributes former employees’ continued access to an Apple access-control or offboarding failure, and argues that the lawsuit could restrain a potential competitor and employee movement. The case remains unresolved.

Apple filed the federal lawsuit on July 10, 2026, in the U.S. District Court for the Northern District of California. The defendants named in the supplied evidence are OpenAI, io Products, Tang Yew Tan, and Chang Liu.

OpenAI denies Apple’s trade-secret case

The dispute is not about a court finding that OpenAI stole Apple information. It is a live civil lawsuit in which Apple has made allegations and OpenAI has presented a defense.

Apple says former employees and OpenAI were involved in obtaining or exposing protected information connected to hardware designs, manufacturing processes, component technology, testing methods, suppliers, and the supply chain. OpenAI denies that account. Its position is that Apple has not demonstrated trade-secret theft or unlawful use, and that the access at issue resulted from Apple’s own failure to remove former employees’ access properly.

OpenAI also frames the case as a competitive fight. It says Apple is using litigation to slow a potential hardware rival and discourage employees from moving to OpenAI. That is OpenAI’s characterization of Apple’s motive, not a judicial finding.

What Apple alleges

Apple’s complaint describes an alleged coordinated pattern involving confidential hardware and manufacturing information. The claimed categories include product designs, production methods, supplier information, and related technical material. Apple also alleges that Chang Liu retained an Apple laptop and accessed Apple systems after leaving the company. Those claims are disputed.

Apple further alleges that candidates recruited from Apple were asked to bring “Actual parts” and other confidential material to OpenAI interviews. The allegation is part of Apple’s case; it does not establish that any particular information was taken, qualified legally as a trade secret, or was used by OpenAI.

One reported document collection connected to Apple’s allegations contained more than 1,000 pages. That figure describes an alleged collection, not a court determination about its contents or legal status.

The initial lawsuit also connected the accusations to OpenAI’s broader consumer-hardware effort. The supplied evidence does not identify a final device. Rumors about a phone or another specific product remain unconfirmed, so there is no reliable product announcement to attach to this case.

The report presents the initial allegations involving product designs, manufacturing processes, and supply-chain strategies. It predates OpenAI’s later response and does not establish that information was taken, that OpenAI benefited from it, or that the allegations are true.

What OpenAI says happened instead

OpenAI’s defense has three main parts.

First, OpenAI denies that it wanted or used other companies’ trade secrets. It says its focus is developing its own technology and that Apple has not shown the essential link between the alleged access and any unlawful use.

Second, OpenAI disputes Apple’s account of access after departure. OpenAI says Apple failed to revoke access to files or systems properly, making any continued access an Apple security or offboarding failure rather than evidence of an OpenAI theft scheme. The supplied evidence does not resolve which account a court will accept.

Third, OpenAI says the lawsuit is also about competition. In its view, Apple is attempting to slow a possible hardware competitor and make it harder for employees to leave. Again, that is a defense argument about Apple’s purpose, not an established fact about the company’s motive.

The people and companies at the center

Apple is the plaintiff. OpenAI and io Products are the corporate defendants. Tang Yew Tan and Chang Liu are the individual defendants named in the supplied account.

Tang Yew Tan later became OpenAI’s chief hardware officer after a reported 24 years at Apple. Chang Liu, identified as a former Apple electrical engineer, worked at Apple for a reported eight years before joining OpenAI. Their employment histories help explain why the lawsuit focuses on employee movement and access to confidential information, but they do not prove the allegations against either person.

The wider technology context includes ChatGPT and Apple Intelligence. Apple and OpenAI announced an integration between ChatGPT and Apple Intelligence in June 2024. That earlier partnership provides important background: the companies had a formal connection before the lawsuit placed them in direct conflict over OpenAI’s hardware ambitions. The supplied evidence does not establish the partnership’s current status.

What the procedural timeline shows

The supported timeline is straightforward, but its legal meaning matters:

Expedited discovery is a request about the pace of evidence collection. It is not a ruling on who is right. The supplied evidence establishes that Apple sought it, but not whether the court granted, denied, or modified the request.

The case is governed in part by the federal Defend Trade Secrets Act, 18 U.S.C. § 1836. In general terms, that law can allow injunctions and damages when its legal requirements are met. Its presence in the case does not mean those requirements have been satisfied here.

Why the lawsuit matters for OpenAI hardware

The legal fight arrives as OpenAI pursues a broader consumer-hardware strategy, but the evidence does not identify the final product. That distinction is crucial. A lawsuit tied to an unnamed hardware effort does not confirm a phone, headset, computer, or any other specific device.

The conflict also highlights a practical tension in technology companies: experienced employees carry knowledge from one employer to another, while companies try to protect information that they claim is confidential. The legal question is not simply whether a person changed jobs. It concerns what information was accessed, whether it was protected under the law, how it was obtained, and whether it was used unlawfully.

That is why the access-control dispute matters. Apple’s account emphasizes alleged conduct by former employees and OpenAI personnel. OpenAI’s account emphasizes Apple’s own systems and employee offboarding. The competing narratives point to different explanations for the same underlying question, and the supplied evidence does not settle it.

What has not been decided

No supplied court finding establishes that OpenAI stole or used Apple trade secrets. The evidence also does not establish that the disputed information legally qualifies as a trade secret, that OpenAI benefited from it, or that any individual defendant is liable.

The clean takeaway is therefore less dramatic than the allegations: Apple filed a serious lawsuit connected to confidential hardware and supply-chain information; OpenAI has denied the claims and challenged Apple’s account of access; and the reported request for faster discovery does not amount to a liability ruling.

For readers watching the technology industry, the next meaningful developments will be the court’s treatment of the competing access accounts and the evidence both sides present. Until then, the OpenAI Apple trade-secrets lawsuit is a contested legal fight—not proof that trade secrets were stolen, and not proof that OpenAI’s hardware project used Apple technology.
