Apple sues OpenAI over trade secret theft, email mix‑up stalls talks

Apple filed a federal trade‑secrets lawsuit accusing OpenAI of stealing hardware designs, then an email error by Apple’s outside counsel derailed any chance of early resolution [1].

Email error that broke off negotiations

NBC News reported that Apple’s outside attorney, Gabriel Gross of Weil, Gotshal & Manges, mistakenly sent a follow‑up email to OpenAI general counsel Che Chang instead of a former Apple employee named Wang [1]. The second email thanked Chang for a phone call that never occurred, prompting Chang to accuse Apple’s lawyers of fabricating evidence and to request removal from the case [1]. The miscommunication coincided with the end of informal talks that Apple had pursued after raising concerns in February [1]. OpenAI maintains it responded to Apple’s initial outreach, but the mistaken email caused the dialogue to collapse [1].

Legal backdrop and broader implications

Apple’s complaint alleges that former staff—Chang Liu, an ex‑senior systems electrical engineer, and Tang Tan, a former VP of product design—brought laptops, designs, and prototypes to OpenAI, constituting “the tip of the iceberg” among more than 400 ex‑Apple hires now at OpenAI [2]. The suit seeks an injunction to preserve evidence, the return of alleged trade secrets, and damages.

The case mirrors a parallel dispute where xAI sued OpenAI over alleged poaching, only to have its claims dismissed twice for relying on speculation rather than concrete misappropriation [2]. Both lawsuits test the limits of the Defend Trade Secrets Act: whether aggressive hiring of rival talent can be deemed illegal misappropriation or simply competitive recruitment [2]. Apple’s filing follows a deteriorating partnership—after a 2024 Siri collaboration, OpenAI’s hardware push, including the $6.4 billion acquisition of Jony Ive’s io Products, has strained relations [2].

Market reaction and corporate hiring risk

The lawsuit underscores a growing concern for tech firms that aggressively recruit from rivals: the potential for inadvertent disclosure of proprietary information and the legal exposure that can follow. While Apple’s claims are untested, the email mishap illustrates how procedural errors can amplify litigation risk and delay settlement talks. OpenAI’s response—that it has “no interest in other companies’ trade secrets”—frames the dispute as a defensive stance rather than an admission of wrongdoing [2].

What to watch

• Court schedule – Apple’s case has not yet been assigned a trial date; any upcoming motions could signal the pace of the dispute.
• Potential settlement – If the parties resume talks, the email error may be a focal point for negotiating confidentiality safeguards.
• Hiring trends – Monitor whether other AI firms adjust recruitment policies to mitigate trade‑secret exposure after this high‑profile case.

The lawsuit’s outcome will clarify how U.S. courts interpret aggressive talent acquisition under trade‑secret law, and whether the email slip‑up will become a cautionary footnote or a pivotal factor in the case’s resolution.
