Ex-Apple Engineer Joins OpenAI With Secrets?

Apple Inc. has initiated legal action against former iPhone engineer Chang Liu, who recently transitioned to OpenAI's developing hardware division. Filed on Friday, July 11, 2026, the lawsuit accuses Liu of departing with proprietary company secrets and a company-issued MacBook that was never returned.

The departure and subsequent lawsuit underscore the high stakes and fierce competition in the technology sector, particularly between major players in artificial intelligence and consumer electronics. Apple's legal filing suggests a concern over the potential misappropriation of its intellectual property by a rival.

This development comes as OpenAI continues to expand its capabilities and personnel, while Apple maintains its focus on innovation and protecting its trade secrets. The specific nature of the information Liu allegedly took remains a key point of contention in the ongoing legal proceedings.
