filed a lawsuit against OpenAI in the US District Court for the Northern District of California, accusing the AI company of systematically stealing trade secrets to accelerate its consumer hardware ambitions.

The complaint names the OpenAI Foundation, OpenAI Group PBC, its hardware subsidiary io Products, Chief Hardware Officer Tang Tan, and former Apple engineer Chang Liu as defendants in the suit.

Apple alleges that OpenAI recruited more than 400 former Apple employees and used them to extract confidential information about unreleased products.

According to the filing, Liu kept a company-issued MacBook after leaving Apple, exploited an authentication flaw to access Apple's internal cloud storage, and downloaded thousands of confidential hardware documents.

Tan, who spent 24 years at Apple before joining OpenAI, allegedly instructed Apple employees interviewing with OpenAI to bring unreleased components and prototypes to interviews for show-and-tell sessions.

Apple also alleges that OpenAI misled one of its industrial design partners into believing it had permission to replicate a proprietary metal-finishing process for OpenAI devices. The company is seeking monetary damages and an order requiring OpenAI to halt the conduct and destroy any proprietary materials.

The recruitment drain

The lawsuit's immediate effect may be felt before any court ruling.

OpenAI's aggressive hiring from Apple's hardware teams was so severe that Apple was forced to rebuild parts of its iPhone product design organization.

Apple responded with unusually large retention bonuses and sent senior executives to personally persuade engineers to stay.

The lawsuit itself could slow OpenAI's recruiting pipeline, since even interviewing with OpenAI may now expose Apple employees to scrutiny from Apple's security team.

Bloomberg Intelligence wrote that Apple is likely to secure preliminary relief tied to OpenAI's device effort, which could require disputed materials to be isolated and compliance certified.

OpenAI still believes it is on track to announce its first product this year and release it in 2027, though the company acknowledged that could change as it digests the claims.

The lawsuit also threatens OpenAI's supply chain relationships, since Apple's market power could cause Asian electronics suppliers to reconsider deepening ties with the AI startup.

A broader IP war

The Apple-OpenAI clash isn't the only IP fight hitting the AI industry.

Anthropic recently sent a letter to Congress accusing Alibaba of illicit AI distillation attacks, alleging it generated 28.8M outputs from Claude using nearly 25,000 fraudulent accounts over roughly six weeks.

OpenAI separately accused China-based DeepSeek of ongoing efforts to free-ride on its work, and the White House identified distillation as a key national security challenge in April.

The sparring extended to social media after Apple filed its suit, with Musk and Altman exchanging pointed posts on X, where Musk called Altman a scammer and Altman denied being afraid of Apple.

Apple's lawsuit has already altered the competitive dynamics of the AI hardware race, regardless of how or when a court ultimately decides the case.
