Apple alleges OpenAI stole trade secrets from over 400 former staff, naming chief hardware officer Tang Tan and engineer Chang Liu in a Northern California

Apple filed a lawsuit in the Northern District of California on Friday accusing OpenAI of stealing trade secrets related to upcoming Apple products, a claim that could jeopardize OpenAI’s hardware ambitions and its partnership with Apple’s Siri platform [1].

| At a glance | |
|---|---|
| Plaintiff | Apple Inc. |
| Defendant | OpenAI (ChatGPT maker) |
| Named individuals | Tang Tan (Chief Hardware Officer), Chang Liu (former Apple engineer) |
| Alleged theft | Over 400 former Apple employees now at OpenAI; confidential files, parts, and designs allegedly taken |

## Allegations and legal claims  
Apple’s complaint says OpenAI “encouraged Apple employees to share information, components, drawings and other materials” as the AI startup builds its own hardware line. The suit names Tang Tan, who spent 24 years at Apple leading iPhone, Watch and AirPods design, and Chang Liu, who downloaded dozens of unreleased Apple hardware files after moving to OpenAI in January. Apple claims the defendants “coached departing employees on how to avoid the ‘dreaded walk out’” to keep accessing Apple’s confidential data [1][2].

The filing also alleges that OpenAI’s hardware business rests on “the shakiest of foundations” because it allegedly relies on misappropriated Apple secrets. Apple is seeking a jury trial, an injunction to stop the alleged practices, destruction of any proprietary materials, and redesign of OpenAI’s upcoming products to remove any Apple‑derived technology [1].

## Market context and competitive implications  
The lawsuit arrives as OpenAI prepares for an initial public offering and has recently acquired the design firm io Products—co‑founded by former Apple chief designer Jony Ive—for $6.5 billion. OpenAI’s push into hardware, including AI earbuds and a smartphone, aims to diversify revenue beyond its subscription model, a move that could be hampered if the case forces redesigns or damages the partnership that lets Apple users access ChatGPT via Siri. Apple’s own AI‑focused hardware roadmap—smart glasses, pendants and camera‑equipped AirPods—relies on protecting its proprietary designs, making the dispute a litmus test for talent‑poaching practices in the AI race [1][2].

OpenAI’s relationship with Apple has already soured; Bloomberg reported earlier this year that OpenAI considered legal action over a perceived lack of benefit from the Siri integration. The current suit could further strain that collaboration, potentially prompting Apple to seek alternative AI partners or accelerate its own in‑house solutions.

## What to watch
- **Court filings and motions** – any court‑ordered injunctions or discovery that reveal the extent of alleged data transfers.  
- **OpenAI hardware rollout timeline** – whether product launches are delayed or redesigns are announced following the suit.  
- **Apple‑OpenAI partnership status** – updates on Siri integration or new AI collaborations after the filing.

The case underscores how aggressively both Apple and OpenAI are protecting—or contesting—intellectual property as AI becomes central to next‑generation devices, and it may set a precedent for future talent‑poaching disputes in the tech sector.
