Apple alleges former employee destroyed evidence of trade-secret theft tied to OpenAI
Apple escalated its trade-secrets lawsuit against OpenAI on August 31, 2026, filing new court evidence that former iPhone engineer Chang Liu downloaded a confidential Apple circuit schematic and used it in work at OpenAI. According to reporting from TechCrunch and Bloomberg, Apple also alleges Liu enlisted colleague Yu-Ting Peng to destroy evidence in June after learning he was under investigation. Apple is seeking a preliminary injunction that could temporarily block OpenAI from developing hardware based on Apple technology while litigation continues. The filing arrives amid broader industry attention to OpenAI's hardware ambitions, including custom silicon and large Mac purchases for reinforcement learning. Courts have not ruled on the injunction or independently verified Apple's allegations, and OpenAI's response in the filing is not fully detailed in the available excerpts.
Apple alleges former employee destroyed evidence of trade-secret theft tied to OpenAI
Apple filed new evidence in its lawsuit against OpenAI, alleging former employee Chang Liu used a confidential Apple circuit schematic at OpenAI and enlisted colleague Yu-Ting Peng to destroy evidence in June after learning he was under investigation. Apple is seeking a preliminary injunction that could block OpenAI from working on hardware based on Apple's technology while the case proceeds.
Key takeaway
A preliminary injunction request could freeze OpenAI hardware work tied to Apple's schematics while courts weigh trade-secret claims.
What happened
Apple filed new evidence in its ongoing lawsuit against OpenAI, alleging former iPhone engineer Chang Liu downloaded a confidential Apple circuit schematic and used it in work at the AI company, according to TechCrunch and Bloomberg reporting.
Apple also claims Liu enlisted colleague Yu-Ting Peng to destroy evidence in June after learning he was under investigation, and is seeking a preliminary injunction that could block OpenAI from hardware work based on Apple technology while the case proceeds.

Why it matters
The dispute tests how courts police IP flows between device makers and frontier labs as both race into custom AI hardware.
Limits and uncertainties
Available excerpts report Apple's court filing allegations; they do not include a full OpenAI response or an independent judicial finding.
The Stratechery excerpt in the packet contains only paywall boilerplate, not substantive reporting on Apple or OpenAI hardware.
Practical implications
Teams building custom AI hardware should treat schematic, firmware, and design-document access controls as litigation-sensitive during employee transitions.
Operators tracking OpenAI hardware roadmaps should monitor whether a preliminary injunction is granted before assuming continued work on Apple-derived designs.
What to watch
Whether a court grants Apple's preliminary injunction blocking OpenAI hardware work tied to Apple's technology.
How expedited discovery proceeds and what additional evidence each side submits in the trade-secrets case.
