Apple Escalates OpenAI Lawsuit, Alleges Evidence Destruction and Stolen Chip Schematics

The Quick Take

• Apple escalated its trade-secret lawsuit against OpenAI, filing new court documents alleging OpenAI is actively destroying key evidence related to stolen circuit diagrams.
• A former iPhone engineer who joined OpenAI is alleged to have not only downloaded Apple's confidential chip schematics but also used them in his OpenAI work.
• Separately, OpenAI reportedly purchased Mac mini computers in bulk — reportedly by the ton — to use as AI training infrastructure.

Apple's trade-secret litigation against OpenAI entered a more combative phase, with Apple filing new court documents accusing OpenAI of accelerating the destruction of evidence relevant to the case. The core allegation is that Chang Liu, a former iPhone engineer who joined OpenAI in January, downloaded a confidential Apple circuit schematic and subsequently used it in his OpenAI role — a claim that, if proven, would establish trade-secret misappropriation at the product-design level rather than merely information leakage. Liu is one of more than 400 engineers Apple says have defected to OpenAI, which is accelerating into hardware-adjacent AI development.

The lawsuit's escalation carries significant market implications for both Apple and OpenAI's future hardware ambitions. If Apple prevails, it could secure injunctive relief that constrains OpenAI's ability to hire from Apple's hardware talent pool or commercialize any designs that benefited from the alleged transfers. For Apple, the legal offensive signals a strategic defensiveness about its custom silicon advantage — the proprietary chip architecture behind the M-series and A-series processors is a core competitive moat. Meanwhile, reports of OpenAI stockpiling Mac minis for AI training at scale suggest OpenAI views Apple Silicon as meaningfully competitive with Nvidia GPUs for certain inference workloads.

The key forward signals are the court's ruling on Apple's evidence-destruction motion — if the court issues a spoliation sanction against OpenAI, it would dramatically weaken OpenAI's litigation position. Investors in Microsoft (a major OpenAI backer) should watch for any escalation into a broader intellectual property dispute that could complicate OpenAI's product roadmap. The macro variable is the broader AI talent war between Apple, OpenAI, Google, and Meta, which determines the pace at which hardware trade secrets flow between Silicon Valley's most valuable companies.
