Apple sues OpenAI alleging trade secret theft, says scheme was 'at every level'

Apple on Friday sued OpenAI in federal court in Northern California, alleging trade secret theft, saying that the artificial intelligence lab took the iPhone maker's intellectual property in order to develop its own consumer hardware.
"This much is clear, however: at every level, from members of its Technical Staff to its Chief Hardware Officer, and in coordination with business partners, OpenAI has been stealing Apple's trade secrets and confidential information," the company said in a legal filing.
It's a shocking reversal for the two companies, which entered into a high-profile partnership in 2024, when ChatGPT was integrated into the iPhone's operating system. OpenAI CEO Sam Altman visited Apple's headquarters for the announcement.
But relations between the two companies have chilled since OpenAI announced plans to enter the hardware industry last year, when it bought former Apple designer Jony Ive's startup, called IO Products, for $6.4 billion.
Apple's updated version of its Siri assistant, which is coming out this fall, is based on Google's Gemini AI models instead of OpenAI's technology.
Most of Apple's allegations involve former employees who have interviewed with or joined OpenAI.
Apple alleged that OpenAI's hardware chief, Tang Tan, who is a former Apple vice president, has directed Apple employees interviewing at OpenAI to share Apple secrets as part of the interviewing process. Tan is named as a defendant in the suit.
"He has directed job candidates still working for Apple to bring 'actual parts' from Apple to their interviews for 'show and tell' sessions in which he and his team at OpenAI can elicit still more Apple confidential information," Apple said in the filing.
Apple alleged that OpenAI coached departing Apple employees in how to evade security processes when leaving the iPhone maker, and that Chang Liu, a former employee who joined OpenAI, stole an Apple laptop. Liu is named as a defendant in the suit.
It also said that Apple believes OpenAI is asking hardware firms to carry out a metal finishing technique that Apple invented, while "misleading the partner to believe they had Apple's permission to do so."
"Recently, significant evidence has emerged suggesting individuals employed by OpenAI wrongfully took Apple's secret and confidential information regarding our unreleased technologies, processes, and products," an Apple representative told CNBC in a statement.
"We have no interest in other companies' trade secrets. We remain focused on building innovative technology that empowers people everywhere," a representative for OpenAI said in a statement.
IO Products is also named in the lawsuit.
OpenAI hasn't announced when or what its hardware products will be, but Altman said in November that it had finished its first prototypes.
Apple didn't comment on whether the lawsuit will affect the partnership with OpenAI, which includes the integration of ChatGPT into Apple Intelligence.
Mounting legal woes present another risk to OpenAI as it gears up for what's expected to be a historic IPO.
Apple's complaint comes two months after OpenAI won a high-profile trial against Tesla and SpaceX CEO Elon Musk. A federal jury found that Musk, who helped start OpenAI, had waited too long to sue the AI lab over claims that Altman, co-founder Greg Brockman and the company reneged on agreements to run it as a nonprofit. Musk said he would appeal.
Apple is seeking damages, injunctions, and an order to force OpenAI to stop using its trade secrets.

Executive Summary

Apple sued OpenAI in federal court alleging trade secret theft, claiming the AI lab acquired intellectual property to develop consumer hardware. The complaint asserts that individuals at OpenAI, including hardware chief Tang Tan and former employee Chang Liu, allegedly directed employees to share Apple secrets during interviews and stole physical assets like a laptop. This action follows a high-profile 2024 partnership where ChatGPT was integrated into the iPhone's operating system, involving CEO Sam Altman visiting Apple headquarters. The dispute is complicated by other developments, such as Apple’s upcoming Siri update being based on Google's Gemini models instead of OpenAI technology, and the context of OpenAI's prior acquisition of Jony Ive's startup, IO Products. While OpenAI denied wrongdoing, stating they focus on building technology, Apple seeks damages and injunctions against OpenAI.

Full Take

The conflict reveals a tension between proprietary innovation and the dynamics of collaborative, rapidly evolving technological partnerships. The core pattern involves the potential commodification of intellectual property embedded within highly specialized knowledge transfer processes, particularly when entities with distinct strategic goals—one focused on consumer ecosystems and the other on foundational AI—interact. The shift from a cooperative integration to litigation suggests a fundamental incompatibility in how the value derived from shared innovation is defined. Furthermore, the narrative highlights the vulnerability inherent in relying on non-disclosure agreements and internal controls when integrating highly sensitive data across organizational boundaries, especially when talent migration occurs between proprietary corporate structures. The fact that Apple’s successor hardware is pivoting away from OpenAI technology toward Gemini suggests a strategic move to reclaim control over its foundational ecosystem, which complicates the narrative of shared future development. The persistence of lawsuits following high-profile wins by AI proponents indicates that legal recourse remains an active mechanism for asserting boundaries against perceived infringements on proprietary advantage.

Sentinel — Human

Confidence

The text appears to be a factual report of a legal claim, characterized by direct citations and specific allegations, suggesting human journalistic sourcing rather than synthetic generation.

Signals Detected

Moderate sentence length variance and use of direct, legalistic citation structure.

The flow between the core allegations and subsequent context (e.g., Jony Ive acquisition, Siri updates) is logical, but the tone remains strictly reportorial.

Clear attribution of specific allegations to named individuals (Tan, Liu) and citing a formal legal filing provides strong grounding, typical of factual reporting.

No obvious linguistic markers of machine generation; the complexity lies in synthesizing legal claims rather than generating narrative.

Human Indicators

The inclusion of specific, named defendants and allegations involving former employees and internal operational details suggests grounded reporting.

The structure transitions naturally from the lawsuit details to contextual background about Apple/OpenAI relations.
