Apple alleges OpenAI employee accessed circuit plans after joining startup

Apple ​on Monday alleged ​that a defendant in ​its trade secret case against ChatGPT creator OpenAI accessed a power converter ‌circuit ⁠schematic while ⁠at OpenAI, according to a ​filing in U.S. federal court.

Apple alleged that ​Chang Liu, a former Apple senior system electrical engineer, accessed ​the circuit and ⁠trained an ‌AI agent using ​proprietary ​Apple information in March ⁠2026.

Apple says the new evidence came ​to light from a ​MacBook computer OpenAI provided to Apple on August 21 as part of legal proceedings.


Apple is asking a U.S. ‌federal court to expedite discovery proceedings in the trade ​secret ​case against ⁠OpenAI.

OpenAI has sought to dismiss Apple's lawsuit, saying it is building products ​that are "entirely new."

OpenAI did not immediately respond to a request for comment.
