Quoted excerpts belong to the original outlet._ Apple’s newest filing doesn’t prove trade secret theft in any court-tested sense yet — it’s an “initial forensic analysis” of one recovered MacBook, offered to win a procedural fight over expedited discovery, not a verdict. What it does establish, if Apple’s characterization holds up, is a genuinely new kind of evidentiary problem for trade-secret litigation in the AI era: Apple says former engineer Chang Liu didn’t just copy a confidential circuit schematic after leaving the company in January, he fed it into an AI agent that “learned how to run LTspice” and iterate simulations on it, according to messages Apple quotes in the filing (also reported by 9to5Mac and MacRumors). > Apple’s most consequential claim isn’t that Liu copied a file — it’s that once a trade secret gets fed into a self-improving AI agent, deleting the laptop doesn’t undo the leak. That’s the detail worth watching for anyone tracking data provenance disputes: Apple is arguing in its filing that when trade-secret information is absorbed into an AI agent or model, the resulting learning “may create irreversible and continually propagating uses” of that secret — a theory that, if a judge credits it, extends discovery and injunction exposure well past the original document. It also explains why Apple wants the Mac mini that synced the schematic to Liu’s MacBook, and why it’s pushing so hard for speed: if trade secrets can be metabolized into a model’s weights or an agent’s learned behavior rather than sitting in a discoverable file, the usual remedy — return the documents, delete the copies — stops being sufficient. The rest of the filing is more conventional but still contested. Apple alleges Liu and OpenAI colleagues knew about his lingering access to Apple’s third-party cloud storage, that he directed a colleague to wipe devices once he learned he was under investigation, and that a tool he used at OpenAI shares a name with an internal Apple engineering application — claims OpenAI has not yet responded to directly, per TechCrunch. OpenAI’s prior defense, that Liu’s continued access was “residual” and caused by Apple’s own offboarding failures, doesn’t obviously answer the alleged instruction to erase evidence, which is a harder fact pattern to wave away than a stale login. Scale is the other number doing quiet work here: Apple’s original complaint named just two defendants, Liu and Tang Tan, but its broader filings already claim more than 400 former Apple employees now work at OpenAI, and Engadget reports Apple has since widened its allegations to cover 11 of them. Judge Edward J. Davila hears arguments October 1, and the near-term question isn’t whether OpenAI stole anything — it’s whether “shocking” forensic fragments from one laptop are enough to unlock the fast-tracked depositions and document production that would let Apple test that broader claim against the other 399. > “The MacBook represents the very limited information Defendants provided so far (and only after weeks of delay), and shows Apple is not conducting ‘fishing expeditions’ but that its trade secrets are being used and evidence is being destroyed,” the filing reads. > — [TechCrunch AI](https://techcrunch.com/2026/08/31/apple-shares-shocking-evidence-against-former-employee-accused-of-stealing-company-data-for-openai/) [Read the full story at TechCrunch AI →](https://techcrunch.com/2026/08/31/apple-shares-shocking-evidence-against-former-employee-accused-of-stealing-company-data-for-openai/) --- Cite this analysis: https://datacommenter.com/apples-macbook-evidence-against-openai-hinges-on-an-ai-agent-not-just-a-file/ Cite primary facts: https://techcrunch.com/2026/08/31/apple-shares-shocking-evidence-against-former-employee-accused-of-stealing-company-data-for-openai/ Need the underlying datasets (alt data, market data, AI training data)?
