Apple sends legal preservation letters to ~40 former staff now at

Apple has dispatched legal preservation letters to roughly 40 former Apple engineers now employed by OpenAI, widening the scope of its trade‑secret lawsuit filed last week [2]. The letters demand that recipients keep all relevant documents and communications, a step that could pressure OpenAI to disclose internal details and test the durability of its talent pipeline.

Expansion of the lawsuit

Apple’s initial complaint named OpenAI and its affiliate io Products as defendants, and singled out two ex‑Apple staff—Chang Liu and Tang Tan—for allegedly funneling proprietary information to the AI firm [1]. The new preservation letters suggest Apple believes the alleged theft may involve a broader group of its former workers, prompting the company to secure evidence before any further discovery. By formally notifying these employees, Apple aims to prevent the destruction or alteration of potential proof, a standard move in high‑stakes IP litigation.

Implications for OpenAI and the AI talent market

The outreach to dozens of engineers underscores how closely tied OpenAI’s talent pool is to Apple’s former workforce, a trend noted in earlier reporting on the lawsuit [1]. If Apple can demonstrate that multiple ex‑Apple staff contributed confidential material, the case could set a precedent for how tech firms protect AI‑related IP when employees jump to rivals. For OpenAI, the letters add legal friction to its rapid hiring strategy and may force the company to tighten internal data‑handling protocols. Competitors watching the dispute will gauge whether similar preservation demands could be leveraged in their own talent‑acquisition battles.

What to watch

• Further filings – Any additional subpoenas or court orders extending beyond the initial 40 letters could signal escalation.
• OpenAI’s response – Statements or filings from OpenAI addressing the preservation requests will indicate how the company plans to defend its hiring practices.
• Talent movement trends – Monitoring subsequent hires from Apple or other hardware firms into AI startups may reveal whether the lawsuit deters cross‑industry poaching.

Apple’s move highlights the growing legal complexities surrounding AI talent migration and the protection of proprietary technology. Whether the preservation letters will uncover substantive evidence remains to be seen, but the case could shape how future disputes over AI‑related trade secrets are litigated.
