Apple vs. OpenAI: A High-Stakes Trade Secrets Showdown

Apple and OpenAI are locked in an increasingly bitter legal fight, with each side accusing the other of mishandling confidential information. In a brief filed in the Apple vs. OpenAI lawsuit, OpenAI says Apple has not assured it that it is not in possession of and has not used OpenAI confidential data. That reciprocal allegation comes as Apple pursues claims that OpenAI misappropriated trade secrets related to hardware development.

The latest flashpoint: a federal judge on October 13 ordered expedited access to selected OpenAI records and device evidence ahead of an October 14 hearing on Apple's request for an injunction and OpenAI's motion to dismiss. Judge Edward J. Davila partially granted Apple's request for accelerated evidence production, citing a risk that critical forensic evidence could be destroyed, according to people familiar with the matter. The order covers forensic images of devices, certain interview materials, LINE (4689.T) messages between former Apple employees Chang Liu and Alyssa Peng, and records concerning former Apple employees' responsibilities at OpenAI. Liu, Peng, and OpenAI hardware chief Tang Yew Tan must also sit for early depositions.

Not a Finding of Wrongdoing

Importantly, the October 13 order is not a finding that OpenAI stole trade secrets. It is a procedural win for Apple that allows the company to gather evidence before the October 14 hearing, where Apple seeks an order stopping OpenAI from using or obtaining allegedly misappropriated Apple information. OpenAI, meanwhile, is seeking dismissal, arguing that Apple has identified broad categories of hardware information rather than specific stolen trade secrets.

Apple alleges improper access to hardware files and recruitment practices designed to elicit confidential information. OpenAI denies wrongdoing and argues that Apple's offboarding failures and requests for continued assistance from Liu explain some of the disputed access. Apple counters that the iCloud exchanges OpenAI relies on are separate from its allegation that Liu exploited an authentication flaw to download files from Apple's network.

The distinction between access, possession, and misuse is critical. Discovery may establish what information crossed company boundaries, but it does not by itself prove that the information qualifies as a trade secret or was unlawfully used. Those remain central contested questions.

Background: From Partners to Rivals

The dispute reflects a shift from partnership to competition. Apple and OpenAI integrated ChatGPT into Apple software beginning in 2024, but OpenAI's hardware expansion now puts the companies into potentially overlapping markets. Apple alleges that confidential design, manufacturing, and supplier knowledge could accelerate that expansion.

Apple's complaint extends beyond device designs to supplier relationships and manufacturing techniques. Reuters (TRI) reports an allegation that a supplier performed a confidential metal-finishing technique for OpenAI believing Apple had authorized its use. These allegations make supplier controls part of the dispute, not merely employee conduct. Apple also alleges that more than 400 employees have moved to OpenAI, highlighting the boundary between hiring experienced engineers and acquiring protected information with them.

OpenAI, for its part, published a detailed rebuttal titled "Apple is getting this wrong," along with messages and correspondence intended to counter Apple's account. That is a party's advocacy, not an independent adjudication. Legal commentators frame the broader debate around innovation, data security, and employees' freedom to carry their skills to a new employer.

The Road Ahead

The immediate questions are whether Apple's complaint survives dismissal, whether an injunction is granted, and what the newly ordered evidence shows. An injunction could restrict use or acquisition of particular information while the case proceeds; it should not be assumed to prohibit all OpenAI hardware development. The hearing on October 14 will be closely watched for signals on how the judge views the strength of each side's arguments.

The strongest available legal analysis identifies two decisive issues: whether Apple can identify specific protectable secrets and whether it can prove misappropriation, rather than merely movement of employees with valuable experience. The broader consequence may be tighter recruitment, offboarding, and supplier-information controls across AI and hardware companies—a plausible implication, not a confirmed corporate response.

Representatives for Apple and OpenAI did not immediately respond to requests for comment.
