Apple OpenAI Trade Dispute Escalates Over Deleted Evidence, Leaked Schematic
Apple’s trade secret lawsuit against OpenAI just got a lot messier. What started in July as a straightforward accusation that two former Apple employees carried proprietary hardware knowledge to their new employer has turned into a courtroom fight over deleted messages, a leaked circuit schematic, and dueling claims about who really failed to protect confidential information.

Key takeaways
- Apple sued OpenAI and its hardware unit io Products on July 10, 2026, in the US District Court for the Northern District of California, alleging misappropriation of confidential hardware designs.
- The complaint names former Apple employees Tang Yew Tan and Chang Liu, both now working at OpenAI.
- New filings claim Liu used a confidential Apple circuit schematic and an internally named engineering tool at OpenAI, and allegedly enlisted colleague Yu-Ting Peng to destroy evidence in June.

- A hearing on Apple’s request for a preliminary injunction and OpenAI’s motion to dismiss is scheduled for October 1, 2026, before Judge Edward J. Davila.
