Key Highlights

• Apple has sued OpenAI, accusing it of stealing trade secrets and breaching contracts through former Apple employees.
• The lawsuit alleges OpenAI executives encouraged recruits to bring confidential Apple information and hardware to interviews.
• Apple claims the alleged misconduct helped OpenAI’s growing AI hardware efforts, including work linked to its acquisition of io.
• OpenAI has denied the allegations, saying it has “no interest in other companies’ trade secrets.”

Apple has filed a lawsuit against OpenAI, accusing the AI company of orchestrating a years-long effort to obtain Apple’s confidential technologies through former employees. The lawsuit alleges trade secret theft, breach of contract, and misuse of proprietary information that Apple says was later used to support OpenAI’s hardware ambitions.

The legal battle, filed in the U.S. District Court for the Northern District of California, marks one of the biggest intellectual property disputes between two of the world’s most influential technology companies. It also comes as OpenAI pushes deeper into AI hardware, a market that could eventually challenge Apple’s dominance.

What does Apple’s lawsuit against OpenAI allege?

According to the complaint, Apple alleges that OpenAI’s senior leadership directed a coordinated effort to obtain confidential information from former Apple employees.

A central figure in the lawsuit is Tang Tan, OpenAI’s Chief Hardware Officer, who spent 24 years at Apple and most recently served as Vice President of Product Design for the iPhone and Apple Watch.

Apple claims Tan used confidential Apple project code names while recruiting employees. The lawsuit also alleges he encouraged job candidates to bring Apple hardware components to interviews, asked departing employees how to bypass Apple’s internal security procedures, and sought information about unreleased Apple products.

Apple argues these actions were not isolated incidents but part of a broader strategy to accelerate OpenAI’s hardware development.

Which former Apple employees are named?

Besides Tang Tan, the lawsuit also names Chang Liu, a former senior systems electrical engineer who worked at Apple for eight years before joining OpenAI in 2026.

Apple alleges Liu failed to return his company-issued MacBook after leaving and used the device to download confidential engineering documents.

According to the complaint, the downloaded files included technical specifications, engineering presentations, proprietary project information, and details related to unreleased Apple technologies.

Apple further claims Liu shared confidential information with other Apple employees considering jobs at OpenAI and even advised at least one applicant on topics likely to come up during interviews.

Why is this lawsuit significant now?

The lawsuit arrives at a critical time in OpenAI’s evolution.

Industry reports have suggested that OpenAI is developing its first consumer hardware device, potentially powered by AI agents instead of traditional mobile applications. If such a device reaches the market, it could compete directly with future iPhone models.

OpenAI significantly strengthened its hardware ambitions after acquiring former Apple design chief Jony Ive’s startup io in a $6.5 billion deal last year. While io is referenced in Apple’s lawsuit, Ive himself is not accused of wrongdoing.

Apple argues that OpenAI’s hardware efforts benefited from confidential company information, including proprietary manufacturing techniques.

One example cited in the lawsuit involves a specialized metal finishing process that Apple says OpenAI used after allegedly misleading a manufacturing partner into believing it had Apple’s approval.

Apple says OpenAI ignored earlier concerns

Apple claims it first contacted OpenAI in February through a formal letter outlining its concerns. According to the complaint, the AI company did not respond. The lawsuit states that Apple’s internal investigation uncovered evidence suggesting former employees shared confidential information during OpenAI’s hiring process. Apple says those findings prompted the company to pursue legal action to prevent any further misuse of its intellectual property.

What is Apple asking the court to do?

Apple wants the court to prohibit OpenAI from using or disclosing any alleged trade secrets obtained through former employees. The company is also seeking an order requiring OpenAI to return confidential Apple materials and preserve all evidence related to the case. Apple believes the legal discovery process will reveal the full extent of the alleged misconduct. In its filing, the company argues that the issue extends beyond individual employees and reflects broader organizational practices inside OpenAI.

How has OpenAI responded?

Following publication of the lawsuit, OpenAI denied the allegations. The company pointed to a public statement shared on X, saying: “We have no interest in other companies’ trade secrets. We remain focused on building innovative technology that empowers people everywhere.” OpenAI has not publicly addressed Apple’s specific allegations involving Tang Tan, Chang Liu, or the company’s hardware development efforts.

What could this mean for the AI hardware industry?

The lawsuit has the potential to reshape one of the fastest-growing areas of the technology industry. OpenAI is widely expected to become a major player in AI-powered consumer devices, while Apple is racing to expand its own artificial intelligence strategy across the iPhone, Mac, iPad, and other products.

If Apple’s allegations are proven in court, OpenAI could face significant legal, financial, and operational challenges that may affect its hardware roadmap. At the same time, the lawsuit highlights how competition in artificial intelligence is expanding beyond software and models into hardware, manufacturing, and intellectual property.

For now, the claims remain allegations that will be tested in court. As the legal process unfolds, the case between Apple and OpenAI could become one of the most closely watched technology disputes of the AI era.
