Apple files lawsuit claiming former employees stole dozens of confidential hardware files for OpenAI, naming two execs and seeking injunctions.

Apple has filed a lawsuit in the U.S. District Court for the Northern District of California accusing OpenAI of stealing Apple’s hardware trade secrets through former employees, naming chief hardware officer Tang Tan and senior engineer Chang Liu as defendants【3】. The suit seeks injunctive relief and damages as OpenAI pushes its own consumer‑hardware lineup.

| At a glance | |
|---|---|
| Plaintiff | Apple Inc. |
| Defendant | OpenAI LP (and io Products) |
| Named individuals | Tang Tan (former VP of product design) and Chang Liu (former senior system electrical engineer) |
| Alleged theft | Dozens of confidential hardware files, CAD artifacts, prototypes, and a “Need to Know” security document |

## Alleged pattern of theft  

Apple’s complaint alleges a “pattern of theft” by OpenAI staff who left Apple, describing how Liu accessed Apple’s internal systems after his departure and downloaded a compilation of technical files exceeding a thousand pages, including detailed manufacturing documents for unreleased products【1】. Tang Tan is accused of using insider knowledge to solicit Apple‑confidential information during job interviews, asking candidates to bring actual Apple parts and CAD designs to “show‑and‑tell” sessions, and distributing an internal “Need to Know” security protocol to new OpenAI hires【2】. The filing also claims OpenAI instructed interviewees to disclose subsystem selections, vendor communications, and proprietary metal‑finishing techniques, suggesting a systematic effort to capture Apple’s hardware know‑how.

## Context and market implications  

The lawsuit arrives as OpenAI expands beyond software, reportedly developing AI‑enabled earbuds, a smartphone slated for a 2028 launch, and a HomePod‑style speaker【2】. If OpenAI succeeds in integrating Apple‑derived hardware designs, it could accelerate its entry into the lucrative consumer‑device market, challenging incumbents like Apple, Samsung, and Google. Apple’s claim that over 400 former employees now work at OpenAI underscores the broader talent‑poaching trend fueling AI hardware ambitions across the industry【2】. The case also follows a Bloomberg report that OpenAI was preparing legal action against Apple over its ChatGPT‑Siri integration, though Apple says that agreement is not part of the current suit【2】.

## Legal and strategic stakes  

Apple’s complaint states that it first raised concerns with OpenAI in February, requesting an investigation that never materialized, and now characterizes the alleged conduct as “the tip of the iceberg”【2】. By seeking injunctive relief, Apple aims to halt any further use of its proprietary designs, preserving its competitive edge in hardware innovation. For OpenAI, the lawsuit could delay or reshape its hardware roadmap, potentially forcing the company to rebuild components without the alleged Apple‑derived inputs.

## What to watch  

- **Court filings and rulings** – Any preliminary injunction or court‑ordered discovery could reveal the extent of the alleged data transfer.  
- **OpenAI hardware timeline** – Updates on the rumored smartphone or AI earbuds will indicate whether the company can proceed without the contested assets.  
- **Talent movements** – Further departures of Apple engineers to OpenAI or other AI firms may trigger additional legal scrutiny.

The case highlights the friction between rapid AI talent acquisition and the protection of core hardware IP, raising questions about how AI firms will source the engineering expertise needed to compete in the consumer‑device arena.
