Apple has escalated a trade-secret dispute involving a former senior system electrical engineer who later joined OpenAI, alleging that proprietary circuit information was accessed after his move to the AI company.
The claims are allegations in ongoing litigation, not established findings of wrongdoing. Reuters reports that Apple says Chang Liu accessed a confidential power-converter circuit schematic and used information from Apple systems while working at OpenAI. OpenAI has sought dismissal of the claims.
Why the case matters
AI competition is increasingly a competition for people as well as models. Engineers move between companies carrying years of expertise in chips, devices, software and systems. The legal question is where accumulated professional knowledge ends and protected company information begins.
That boundary becomes even more complicated when AI tools are involved. Apple alleges that confidential information was used in connection with an AI agent. If courts eventually have to examine how employees use internal documents with AI systems, disputes like this could influence corporate policies far beyond Apple and OpenAI.
The hidden value of hardware knowledge
The generative-AI race is often described as a software contest, but leading AI companies increasingly care about devices, power systems, chips and custom infrastructure. Engineers with deep hardware experience therefore sit at the centre of a widening talent war.
That increases the value of intellectual property surrounding seemingly narrow components. A circuit design may look far removed from a chatbot, yet efficient power conversion and device engineering can become strategically important when AI moves into consumer hardware and embodied systems.

The bigger lesson is that AI companies are becoming full-stack technology companies. As they move into chips, devices, robotics and infrastructure, they will collide more often with the intellectual-property boundaries of established hardware firms.
For employers, the challenge is to protect legitimate trade secrets without pretending employees can erase their skills and experience when they change jobs. Courts will have to separate those two things carefully.
