Apple and OpenAI Head Into a Trade-Secret Fight as Early Filings Land

Apple and OpenAI Head Into a Trade-Secret Fight as Early Filings Land

Apple has taken one of its former engineering hires — and, with him, OpenAI — to federal court, opening what may become the highest-profile trade-secret battle of the AI hardware era. On July 10, 2026, Apple filed suit in the U.S. District Court for the Northern District of California, alleging that OpenAI leaned on poached Apple talent and stolen confidential information to jump-start its push into consumer devices. As of this edition, the case is in its earliest procedural stages, with the parties not yet having joined issue on the merits.

The complaint, captioned Apple Inc. v. Liu et al. (Case No. 5:26-cv-07078), names five defendants: former Apple engineer Chang Liu; Tang Yew Tan (widely reported as "Tang Tan"), OpenAI's hardware chief and a onetime leader of iPhone and Apple Watch product design; OpenAI Foundation; OpenAI Group PBC; and io Products, LLC, the hardware startup co-founded by former Apple design chief Jony Ive that OpenAI acquired in 2025. Notably, neither Ive nor OpenAI CEO Sam Altman is named as a defendant.

All of the following are allegations from Apple's complaint. They are unproven, and no defendant has been found liable.

What Apple Alleges

Apple's core claim is that OpenAI, racing to ship its first consumer hardware device, recruited scores of Apple engineers and executives and exploited their knowledge of Apple's confidential engineering, manufacturing, and supply-chain work. According to a CNN tally of LinkedIn profiles, OpenAI has recently hired at least ten engineers directly from Apple.

The specific misconduct alleged is unusually vivid for a trade-secret filing. Apple says Chang Liu — a senior systems electrical engineer of roughly eight years — failed to return an Apple-issued laptop after leaving for OpenAI in 2026, and used it to download confidential Apple technical documents. Apple further alleges Liu maintained a back channel to a colleague still inside Apple, Yu-Ting "Alyssa" Peng, described in the complaint as a conduit between the two companies. Peng reportedly departed Apple in April 2026 and was hired by OpenAI; she is not currently named as a defendant.

Tang Tan is accused of using Apple's confidential project code names during OpenAI's recruiting process, asking job candidates to bring Apple hardware components to interviews, coaching departing Apple employees on how to evade the company's security procedures, and probing for details about unannounced Apple products. Apple has characterized the alleged scheme as operating "at every level."

Procedural Posture

Apple brings claims under the federal Defend Trade Secrets Act for misappropriation, along with breach-of-contract claims against the two former employees. In its prayer for relief, Apple seeks an injunction barring OpenAI from possessing, using, or disclosing its technologies, an order compelling the return of Apple property, damages "in an amount to be determined at trial," and royalties for use of its intellectual property.

That injunctive demand is embedded in the complaint itself; as of this writing, reporting does not clearly establish that Apple has filed a separate, briefed motion for a preliminary injunction in this matter. An initial case management conference is scheduled for October 13, 2026 — the point at which the case's near-term trajectory, including any expedited injunction fight, should come into sharper focus.

One important disambiguation: a preliminary injunction was issued against OpenAI, Altman, and Ive on April 23, 2026, but in a separate case brought by the startup iyO — a trademark dispute over the "io" name, not the Apple trade-secret matter.

OpenAI has denied wrongdoing. In a statement to multiple outlets, the company said: "We have no interest in other companies' trade secrets. We remain focused on building innovative technology that empowers people everywhere."

The Bigger Pattern

Apple's suit lands in a year already thick with AI trade-secret and talent litigation — from Elon Musk's xAI accusing OpenAI of misappropriation, to OpenAI's own motions to dismiss such claims, to the iyO trademark fight. The through-line is talent mobility: as AI labs pay eye-watering sums to lure engineers, the line between a hire bringing general skill and a hire bringing an employer's protected secrets is where the legal action is. Trade-secret cases hinge on hard-to-prove questions of what was actually taken, whether it qualifies as a secret, and whether it was used — which is why forensic evidence like Liu's alleged laptop downloads tends to anchor these complaints.

What to Watch

The near-term signals: whether Apple moves for expedited or injunctive relief before October, how OpenAI and io Products respond (a motion to dismiss is a likely first move), and whether the case brushes against OpenAI's reported hardware and financing timelines. Also worth watching is whether additional individuals — Peng among them — are later named. For now, the filings are early, the allegations unproven, and the fight just beginning.
