Apple has mailed legal preservation letters to about 40 ex‑employees at OpenAI, signaling a broader push in its trade‑secret lawsuit and hinting at further

Apple has sent legal preservation letters to roughly 40 former Apple engineers now working at OpenAI, demanding they retain any documents that could relate to Apple’s trade‑secret lawsuit against the AI firm [2]. The move widens the scope of Apple’s legal offensive and suggests the company believes more ex‑staff may have misused proprietary hardware designs.

| At a glance | |
|---|---|
| Company | Apple |
| Legal action | Preservation letters to ~40 former employees |
| Targeted ex‑employees | Former iPhone engineer Chang Liu and former VP of Product Design Tang Tan (already sued) |
| Estimated former Apple staff at OpenAI | ~400, with the 40 letters covering about 10 % of that pool |

## Expansion of the legal fight  
Apple’s lawsuit, filed last week, accuses OpenAI and two defectors—Chang Liu and Tang Tan—of stealing confidential hardware designs for use in OpenAI’s nascent consumer‑hardware projects [1]. The preservation letters, a standard step in litigation, instruct the recipients to “preserve documents and communications” that may be relevant to the dispute [3]. By targeting roughly 40 individuals, Apple signals that the alleged misconduct may extend beyond the two named defendants, a claim the company itself described as “just the tip of the iceberg” in its filing [5].

## Implications for OpenAI and the broader AI‑hardware race  
OpenAI is actively building a consumer‑hardware division, having acquired Jony Ive’s design studio io for $6.5 billion and reportedly working on a screen‑less smart speaker [5]. If Apple can demonstrate that former staff transferred proprietary CAD files or prototype data, it could force OpenAI to halt development of any products that rely on the allegedly misappropriated information. OpenAI has denied any evidence supporting Apple’s claims [2]. The letters also serve to put remaining defectors on notice, potentially deterring further use of Apple‑derived knowledge and shaping the competitive dynamics of AI‑enabled hardware.

## What to watch
- **Further discovery requests** – Apple may issue subpoenas or seek court orders for additional evidence from the 40 recipients.  
- **OpenAI’s response** – Any public statements or filings from OpenAI addressing the preservation letters could indicate the strength of Apple’s case.  
- **Impact on OpenAI hardware timeline** – Delays or redesigns in OpenAI’s consumer‑hardware projects may emerge if the lawsuit forces the removal of Apple‑derived components.  

The issuance of preservation letters underscores the escalating legal battle between two of the world’s biggest tech players, raising questions about how talent mobility and intellectual‑property protection will shape the emerging AI‑hardware market.
