Key Takeaways
- Apple says OpenAI and several associated parties misused trade secrets tied to unreleased hardware, prototypes, and confidential design work.
- The complaint centers on former Apple employees, hiring practices, and alleged efforts to bring Apple parts and documents into OpenAI’s orbit.
- The case could complicate OpenAI’s push into AI-powered consumer devices and intensify scrutiny of talent movement between major tech rivals.
What happened
Apple has sued OpenAI and its hardware chief, Tang Tan, alleging that the company obtained Apple trade secrets tied to hardware development. In the lawsuit filed in U.S. district court in San Jose, Apple says the alleged material included unreleased parts, prototypes, confidential designs, and documents related to stealth projects.
According to the complaint, Tan — who spent 24 years at Apple and oversaw iPhone product design — and colleagues at OpenAI encouraged employees who were leaving, or thinking about leaving, Apple to bring proprietary and unreleased information with them. Apple also alleges that Tan helped coach recruits on how to avoid Apple’s data security protocols and told candidates to bring confidential Apple parts to interviews for what the lawsuit describes as “show and tell” sessions.
The complaint names OpenAI, Tan, io Products, and Chang Liu, an electrical engineer at OpenAI who previously worked at Apple until January. Apple says Liu failed to return a company laptop and later wrote to a former colleague about still having access to Apple’s internal file-sharing system. Apple says that access came through a bug that has since been fixed.
Apple alleges that Liu downloaded dozens of confidential hardware-related files, including a presentation on manufacturing and testing complex circuit boards used in Apple hardware. The company also says Liu coached an Apple employee he was recruiting on how to avoid attention from Apple’s security team when copying confidential files.
The complaint goes further, saying Tan emailed himself supplier information before leaving Apple and that other Apple employees who joined OpenAI did the same. Apple also alleges that OpenAI recruiters and Tan used an internal Apple document about departure procedures to advise employees on how to avoid disclosing their new employer, delay loss of system access, and skip exit paperwork.
Apple says it began raising concerns with OpenAI in February after its investigation uncovered the alleged activity, but it says it did not receive a response that resolved the issue. The company now seeks an injunction, monetary damages, and the return of any allegedly taken property or data.
OpenAI, for its part, says it does not want other companies’ trade secrets. Spokesperson Drew Pusateri said the company is focused on building technology that empowers people. Tan did not immediately comment, according to the source material.
Why it matters
This is not just a legal fight about employee departures. It sits at the intersection of hardware secrecy, AI product development, and the increasingly competitive market for AI-powered consumer devices.
Apple argues that OpenAI is under pressure to deliver a first commercial hardware product and says that pressure led to “unlawful shortcuts.” That allegation matters because hardware development usually depends on long lead times, sensitive supplier relationships, and tightly controlled design information. If a company believes a rival’s hardware efforts are being built on misappropriated know-how, the resulting lawsuit can affect more than just the courtroom record. It can also shape hiring, partner relationships, and the pace of product planning.
The dispute also highlights how much value technology companies place on personnel movement. Apple says OpenAI has hired more than 400 former Apple employees, including veterans now helping lead OpenAI’s consumer-device work. It also points to OpenAI’s acquisition of io Products, a startup cofounded by former Apple executives including Tan, Scott Cannon, Evans Hankey, and Jony Ive. That gives the case a broader strategic feel: the argument is not only about isolated documents, but about whether a wave of departures can carry sensitive institutional knowledge into a rival’s hardware ambitions.
The timing matters too. Apple and OpenAI announced a partnership in 2024 to distribute ChatGPT on iPhones, MacBooks, and iPads. But the source material says the relationship has since frayed, and Apple has leaned more on Google’s Gemini AI technology for some of its own models. That suggests the companies may now be moving from complementing each other to competing more directly, especially as OpenAI builds toward its own devices.
The lawsuit also echoes earlier Silicon Valley disputes over confidential technical information and hiring. The source material compares it to the 2017 Waymo-Uber case, another high-profile conflict involving alleged theft of hardware-related know-how. That comparison does not mean the outcomes will match, but it does show why the current case is being watched closely.
What to watch
First, watch how OpenAI responds in court. Apple’s filing contains detailed allegations, but those claims have not been adjudicated. OpenAI’s legal strategy will likely shape whether the case moves quickly toward settlement, fights over evidence, or a longer discovery process.
Second, watch whether the case affects OpenAI’s hardware timeline. The source says OpenAI has described work on a “family” of AI-powered devices and has indicated it will use a different name than io for the products. It also says the company does not expect to ship devices to customers until at least April 2027. Any injunction request or supplier dispute could add pressure to that schedule.
Third, watch the talent and supplier implications. Apple alleges that OpenAI approached suppliers to replicate work and sought detailed questions about components such as batteries and metal finishing. If that part of the case gains traction, it could influence how other hardware vendors handle requests from AI companies and how carefully they manage cross-company relationships.
Finally, watch whether the dispute changes how tech companies handle exits, onboarding, and security reviews for employees moving between rivals. Apple’s complaint suggests it sees departures as a security issue as much as a staffing issue. If that view spreads, the practical rules around talent mobility in hardware and AI could become stricter.
For now, the central issue is straightforward: Apple says its hardware know-how was taken; OpenAI says it does not use other companies’ trade secrets. The court case will determine how much weight those competing claims carry.
