Apple scored a meaningful courtroom win in its Apple OpenAI trade secrets lawsuit on October 13, as a federal judge granted most of the company’s requests for expedited discovery — ordering OpenAI, io Products, and two former Apple employees to turn over forensic evidence, interview materials, and private messages. The ruling lands just one day before a scheduled hearing on Apple’s request for a preliminary injunction, a decision that could shape how quickly the dispute escalates.
U.S. District Judge Edward Davila ruled that Apple is entitled to early access to several categories of documents and testimony it says will help prove its case. The allegations — which OpenAI and the individual defendants dispute — center on claims that former Apple employees Chang Liu and Tang Tan misused confidential Apple information to advance OpenAI’s consumer hardware ambitions. All allegations in the case remain unproven, and no court has found any defendant liable for trade secret misappropriation.
Judge Edward Davila’s Ruling in the Apple OpenAI Trade Secrets Lawsuit
According to 9to5Mac, which reported the decision, Judge Davila granted most of Apple’s expedited-discovery requests while rejecting some and postponing others. Expedited discovery lets a party obtain documents and testimony before the normal, slower schedule of a lawsuit — something Apple argued it needed to support its pending request for a preliminary injunction.
Under the order, the defendants must produce:
- Forensic images already collected in connection with the claims, including material examined by OpenAI’s own forensic expert.
- Interview materials used to guide or conduct interviews of Apple candidates for OpenAI’s Consumer Hardware Products Group — including checklists, guides, instructions, manuals, and scripts, plus Technical Deep Dive presentations and other technical presentations memorializing the content of those interviews or any references to Apple technology.
- LINE messages between Chang Liu and Yu-Ting “Alyssa” Peng dating back to January 1, 2026, including messages cited in a previous filing by the defendants.
The judge also authorized Apple to take depositions of Chang Liu, Tang Tan, and Yu-Ting “Alyssa” Peng, as well as corporate representatives from OpenAI and io Products. The decision addressed whether these expedited depositions will count toward the limits imposed by federal discovery rules, and set deadlines for producing documents and conducting depositions.
What the judge declined to fast-track
Not everything went Apple’s way. Judge Davila rejected Apple’s request for expedited access to OpenAI’s research and development documents concerning metal finishes, power management, and battery functionality for consumer hardware products, ruling that those materials will be addressed through the regular discovery process instead.
The judge also postponed decisions on a set of requests involving what Apple described as “Apple Originated Information.” He found Apple’s definition of the term “amorphous as currently defined” and gave Apple five days to consult with the defendants and submit a narrower definition if it wants another shot at those requests.
The Underlying Complaint: How the Apple OpenAI Trade Secrets Lawsuit Began
The Apple OpenAI trade secrets lawsuit was filed in the U.S. District Court for the Northern District of California in early July 2026. Apple’s complaint names OpenAI, the OpenAI-backed hardware company io Products, Chang Liu, and Tang Tan — a former Apple vice president of product design who left the company in February 2024 — as defendants.
Apple’s central allegation is that Liu and Tan improperly accessed or used confidential information about Apple products and technologies to help advance OpenAI’s consumer hardware development efforts. The complaint further alleges that the defendants improperly obtained information from other Apple employees during recruitment interviews. Apple says it raised its concerns with OpenAI directly in February 2026 and received no response — a claim that, like the rest of the complaint’s assertions, has not yet been tested at trial.
According to Apple’s filing, Liu downloaded more than 1,000 pages of technical files, and Tan allegedly used Apple confidential information while interviewing candidates. Apple has also pointed to the movement of personnel between the companies: more than 400 former Apple employees now work at OpenAI, a statistic the complaint frames as part of the context of the dispute. Apple is seeking a preliminary injunction that would stop the alleged secrets from becoming embedded in OpenAI’s hardware development while the case proceeds.
OpenAI’s pushback
OpenAI opposed the motion for expedited discovery, arguing that Apple’s demands were overly broad and that the fast-track process was unnecessary because regular discovery was about to begin. The judge’s split decision reflects that tension: Apple won access to the evidence tied most directly to its immediate claims — forensic material, interview guides, and specific communications — while the broader requests for R&D documentation and the vaguely defined “Apple Originated Information” were rejected or delayed.
What’s at Stake in the Apple OpenAI Trade Secrets Lawsuit
The immediate question now turns to the preliminary injunction hearing, scheduled for October 14, 2026. A preliminary injunction is a court order that would freeze certain activity while a case plays out — in this instance, Apple wants the court to prevent the defendants from further embedding the alleged trade secrets in their hardware development. Judges grant such injunctions only when the requesting party shows a likelihood of success on the merits and the risk of irreparable harm, making the hearing one of the highest-stakes moments of the case so far. No outcome of the hearing has been confirmed at the time of writing.
The case also sits at the intersection of two of the most competitive races in technology. OpenAI, which has been expanding aggressively across its AI portfolio — see The Nerdy Humourist’s recent coverage of OpenAI’s GPT-6.1 Astra developments — has been building toward consumer hardware through its io Products group, a move that puts it in increasingly direct competition with Apple’s core business. Apple, for its part, has been preparing its own product pushes, including its October event calendar, even as it argues its internal innovations must be protected from competitors.
Trade secret cases involving former employees moving between rival firms are a recurring feature of Silicon Valley litigation, and courts often scrutinize how much of a plaintiff’s information genuinely qualifies as a protectable secret versus general industry knowledge. Judge Davila’s pushback on Apple’s “amorphous” definition of “Apple Originated Information” signals that this case will be no exception: Apple will need to be precise about exactly what secrets it claims were taken.
What Happens Next
With the October 14 injunction hearing on the docket, the coming days should clarify the trajectory of the dispute. If the court grants Apple’s preliminary injunction, OpenAI’s hardware development could face significant constraints for the duration of the litigation. If the injunction is denied, Apple will still have the full regular discovery process — including the R&D materials the judge declined to fast-track — to build its case.
Separately, Apple has five days from the October 13 ruling to consult with the defendants and submit a narrower definition of “Apple Originated Information” if it wants the court to reconsider the postponed discovery requests. The deadlines for document production and depositions authorized under the expedited-discovery order are also expected to move quickly, given that the entire point of the motion was to secure evidence ahead of the injunction hearing.
