Apple Files Trade-Secret Lawsuit Against OpenAI, Targets Former Employees
Apple Inc. filed a federal complaint on July 10 2026 in the U.S. District Court for the Northern District of California, accusing OpenAI of stealing proprietary hardware designs and recruiting Apple staff to facilitate the theft. The lawsuit names two former Apple engineers—Tang Tan, a 24‑year veteran who led product design before joining OpenAI as Chief Hardware Officer, and Chang Liu, a senior systems electrical engineer now on OpenAI’s hardware team—as central figures in the alleged wrongdoing.
Apple alleges that OpenAI carried out a coordinated campaign to poach Apple talent and that the company encouraged former employees to review confidential Apple materials before interviews. The complaint also claims that OpenAI hosted “show and tell” sessions in which incoming engineers allegedly displayed stolen Apple prototypes and design layouts to accelerate OpenAI’s own hardware development. Apple says the misconduct uncovered so far is only the “tip of the iceberg” and seeks unspecified financial damages and an injunction that would bar OpenAI from using any Apple trade secrets while it develops unannounced consumer AI hardware.
To support its case, Apple issued evidence‑preservation letters to roughly forty former Apple employees who have joined OpenAI. Sent shortly after the lawsuit was filed, the letters require recipients to freeze and preserve all communications, electronic files, and device data that might be relevant to the case. According to the complaint, the preservation notices prepare for extensive discovery as the trial approaches and signal that Apple is monitoring the defectors’ output.
OpenAI has publicly denied the allegations for the first time this week. In a statement released on July 15 2026, the company said it was “entirely unaware of any evidence showing the complaint has merit.” OpenAI emphasized its belief in fair market competition and that professionals should be free to work wherever they choose. The company has not provided evidence to counter Apple’s claims.
The case follows Apple’s long‑standing reputation for aggressively protecting its intellectual property. Apple previously litigated over trade secrets, patents, and employee poaching, most notably in a 2025 lawsuit that targeted a former Apple engineer who had joined a competitor. The current lawsuit is significant because it involves a major AI research organization that is reportedly developing its own line of consumer hardware. If the court finds that OpenAI misappropriated Apple trade secrets, it could set a precedent for how AI companies handle proprietary hardware information.
Apple’s complaint also highlights the broader “war for talent” that has intensified in the technology sector. With more than 400 former Apple employees now employed by OpenAI, the lawsuit underscores the challenges companies face in retaining specialized talent while protecting confidential information. The outcome may influence how firms structure non‑disclosure agreements, exit interviews, and post‑employment restrictions.
At present, the lawsuit is pending and no verdict has been issued. Apple has requested an injunction and damages, but the court has not yet ruled on the merits of the claims. OpenAI remains silent on the specifics of its hiring practices beyond the general statement of denial. The case will likely proceed through discovery, where Apple’s preservation letters will play a key role in gathering evidence.
The dispute underscores the growing intersection of AI development and traditional hardware intellectual property. Whether Apple’s allegations prove true will have implications for how AI firms approach hardware design, employee recruitment, and compliance with trade‑secret law. The outcome could also affect the competitive landscape for consumer AI devices, as OpenAI’s hardware ambitions are closely watched by investors and industry analysts.
In the meantime, Apple and OpenAI are likely to continue their legal preparations. Apple’s preservation letters suggest a comprehensive discovery strategy, while OpenAI’s public denial indicates a defensive posture. The case will be closely followed by the technology community, as it may shape future interactions between AI startups and established hardware manufacturers.
