Apple Sues OpenAI Over Alleged Trade Secret Theft by Former Employees

Apple has filed a lawsuit against OpenAI, alleging that three former Apple employees carried confidential information with them when they joined the artificial intelligence company. The case, Apple v. Liu (No. 5:26-cv-07078), filed in the Northern District of California, has escalated quickly. A federal judge recently ordered OpenAI to turn over internal hiring records and materials related to the former employees, setting the stage for a high-profile battle over trade secret protections in the AI industry.

The Dispute

According to Apple’s complaint, former employees Chang Liu, Alyssa Peng, and Tang Yew Tan downloaded proprietary materials before leaving Apple to join OpenAI. Apple alleges that the employees had access to confidential technical information related to Apple’s hardware and AI development initiatives. The lawsuit goes further, claiming that OpenAI’s interview process was structured to extract proprietary knowledge from Apple employees, effectively turning job interviews into intelligence-gathering sessions.

Judge Edward Davila sided with Apple on a critical discovery issue, ordering OpenAI to produce hiring records and internal communications tied to the recruitment of these former Apple employees. A hearing scheduled for October 14, 2026, will address Apple’s motion for a preliminary injunction alongside OpenAI’s motion to dismiss. The outcome could determine whether OpenAI must pause certain product development efforts, including a reported consumer hardware device, while the case moves forward.

Why This Case Matters

Trade secret disputes between technology companies are nothing new, but this case arrives at a particularly critical moment. As companies race to build AI-powered hardware and software, the employees who develop these technologies carry enormous institutional knowledge. The boundary between general expertise that an employee is free to bring to a new job and specific trade secrets that belong to their former employer is often difficult to draw, and the stakes in getting that line wrong have never been higher.

Courts evaluate trade secret claims under the Defend Trade Secrets Act by examining whether the information qualifies as a trade secret, whether reasonable measures were taken to protect it, and whether it was actually misappropriated. Apple’s ability to demonstrate that OpenAI actively solicited confidential information during its hiring process could strengthen its position considerably. If the court grants a preliminary injunction, it would send a clear signal that aggressive talent recruitment in the AI sector carries real legal consequences.

Key Takeaway for Business Owners

This case underscores that protecting trade secrets requires proactive measures, not just good ideas. Businesses of every size should implement strong confidentiality and non-disclosure agreements, conduct thorough exit interviews when employees depart, and maintain detailed records of who has access to sensitive information. On the hiring side, if you bring on employees from competitors, make sure your onboarding process does not encourage or facilitate the sharing of a prior employer’s proprietary information. A well-documented hiring process can be a powerful defense if a trade secret claim ever surfaces.
