Apple Files Lawsuit Against OpenAI, Alleges Systematic Trade Secret Theft by Former Employees

Apple has filed a lawsuit against OpenAI in the U.S. District Court for the Northern District of California, accusing the AI company of orchestrating a campaign to steal confidential trade secrets. The complaint, made public on Friday, centers on allegations that senior OpenAI leaders, including Chief Hardware Officer Tang Tan, directed former Apple employees to misappropriate proprietary information related to unreleased Apple technologies and products.

Allegations of a Coordinated Scheme

The lawsuit details a pattern of alleged misconduct that Apple says was encouraged by OpenAI’s leadership. According to the filing, Tang Tan, who spent 24 years at Apple as a vice president of product design for the iPhone and Apple Watch, used Apple’s confidential project code names during recruiting. The complaint further alleges that Tan asked job candidates to bring Apple hardware components to interviews and coached departing employees on how to bypass Apple’s security protocols.

Apple also names Chang Liu, a former senior systems electrical engineer who worked at Apple for eight years. The company claims Liu failed to return an Apple-issued laptop after leaving for OpenAI in 2026 and used the device to download confidential technical documents, including specifications for unannounced features and products. Liu is also accused of sharing this information with other Apple employees who were applying for jobs at OpenAI.

Context: OpenAI’s Hardware Ambitions

The lawsuit arrives at a time when OpenAI is widely reported to be developing its first hardware product, potentially a smartphone that relies on AI agents rather than traditional apps. Industry analyst Ming-Chi Kuo suggested in April that such a device could pose a significant competitive threat to Apple’s iPhone business. Adding to the tension, OpenAI acquired Jony Ive’s device startup, io, last year in a $6.5 billion deal to bolster its hardware development capabilities. While io is named in the filing, Ive is not.

Apple alleges that OpenAI and its partners have already used its confidential information in their hardware development. The filing specifically references a proprietary metal finishing technique that OpenAI allegedly used after misleading a partner into believing it had Apple’s permission.

Why This Matters for the Tech Industry

This case highlights the intensifying competition between two of the most influential companies in technology. Apple’s hardware business, particularly the iPhone, remains its primary revenue driver. OpenAI’s push into hardware, if successful, would represent a direct challenge. The lawsuit also underscores the high stakes involved in the movement of talent and intellectual property between major tech firms, especially as AI reshapes product categories.

For readers, the outcome could influence how companies protect trade secrets in an era of rapid employee mobility and AI-driven innovation. It also raises questions about the ethical boundaries of corporate espionage in the race to build next-generation devices.

Apple’s Demands and OpenAI’s Response

Apple is seeking a court order to bar OpenAI from using or disclosing its trade secrets, require the return of all confidential materials, and preserve evidence. In a prepared statement, Apple said, "At Apple, our teams are constantly developing breakthrough technologies to create the best products and services in the world, and protecting their work and intellectual property is something we take very seriously."

Apple also stated that it sent a letter to OpenAI in February outlining its concerns but received no response. OpenAI has not yet issued a public comment on the lawsuit. The filing describes the alleged misconduct as "the tip of the iceberg," claiming that Apple lacks full visibility into OpenAI’s internal practices.

Conclusion

The lawsuit represents a significant legal escalation between Apple and OpenAI, with potential implications for the future of hardware innovation and intellectual property protection. As the case moves through discovery, more details are likely to emerge about the extent of the alleged operation. This is a developing story and will be updated as new information becomes available.
