Apple submitted new evidence in its trade secret lawsuit against OpenAI, accusing former senior engineer Chang Liu of downloading confidential circuit schematics and using them to train an AI agent on an OpenAI-provided MacBook. Apple alleges Liu instructed colleagues to reset devices to erase forensic traces after the internal probe began. This case highlights growing intellectual property disputes between tech giants and AI firms as high-level talent mobility increases, potentially reshaping data compliance and talent movement models in the industry.
