Apple sues OpenAI over alleged trade‑secret theft, names 400 ex‑Apple

Apple filed a lawsuit in the Northern District of California accusing OpenAI of misappropriating Apple trade secrets, naming former Apple hardware chief Tang Tan and alleging that more than 400 ex‑Apple staff have joined OpenAI’s hardware effort【1】. The case pits two former partners against each other as both race to launch AI‑centric consumer devices, a clash that could reshape talent flows and product roadmaps in Silicon Valley.

Partnership turned rivalry

Apple’s complaint says OpenAI “coordinated a campaign” to obtain confidential hardware designs, drawings and supplier details, even coaching departing Apple engineers on how to conceal their exits and retain access to internal systems【1】. The suit also alleges that former senior engineer Chang Liu downloaded dozens of unreleased Apple files after leaving for OpenAI in January【1】. Apple had previously tried to resolve the dispute out of court, sending a letter in February that went unanswered before filing the complaint【2】.

The partnership that once integrated ChatGPT into Siri and Apple’s Visual Intelligence features has soured. Apple originally promoted OpenAI as a “pioneer and market leader” in AI at its WWDC two years ago, but the relationship deteriorated as OpenAI pursued its own hardware ambitions, reportedly considering a breach‑of‑contract notice against Apple earlier this year【1】. Analysts note that the lawsuit could delay OpenAI’s hardware rollout and further erode an already fragile collaboration【2】.

Market and talent implications

The allegation that OpenAI has recruited hundreds of Apple engineers underscores the intensifying talent war over AI‑driven hardware. California’s “right‑to‑work” environment makes such poaching legal, but the alleged transfer of confidential files could expose OpenAI to significant liability if proven true【2】. A Stanford law professor highlighted that while hiring former employees is common, the key legal question is whether proprietary documents were taken and used in OpenAI’s product development【2】.

Both companies are betting on next‑generation AI devices—Apple on smart glasses, pendants and camera‑enabled AirPods, and OpenAI on a potential AI‑first phone or other consumer hardware. The outcome of the case may influence how quickly OpenAI can bring hardware to market and whether Apple will accelerate its own AI‑centric product pipeline to protect its ecosystem.

What to watch

• Any court‑ordered injunction forcing OpenAI to destroy or redesign hardware that incorporates alleged Apple designs.
• Timeline for OpenAI’s anticipated IPO and whether the lawsuit impacts investor sentiment or the company’s hardware roadmap.
• Apple’s next product announcements, especially in AI‑focused categories like smart glasses, which could signal a strategic response.

The lawsuit highlights the high stakes of AI hardware competition: if Apple’s claims hold, OpenAI’s hardware ambitions could be hampered; if not, the case may set a precedent for how talent and trade secrets are managed in the fast‑moving AI arena.
