The partnership that placed ChatGPT inside hundreds of millions of Apple devices has collapsed into a federal courthouse. In a lawsuit filed Friday that represents one of the most dramatic ruptures in Silicon Valley's recent history, Apple accused OpenAI of orchestrating a systematic campaign to extract Apple's most sensitive trade secrets — stealing not through servers or hacking, but through the deliberate recruitment of Apple's own people and the confidential knowledge they carried out the door.

The federal complaint accuses OpenAI, two of its employees, and io Products — the design startup founded by legendary Apple designer Jony Ive and acquired by OpenAI last year — of engaging in what Apple describes as "a pattern of theft" of confidential product development information. Apple is seeking an immediate court order barring OpenAI from using any misappropriated information, along with unspecified monetary damages.

"We have no interest in other companies' trade secrets," Drew Pusateri, a spokesman for OpenAI, told the BBC, adding that the company is reviewing Apple's complaint and remains "focused on building innovative technology that empowers people everywhere." An Apple spokesman countered that the lawsuit is the product of "significant evidence."

The Employees Who Allegedly Carried Secrets Through the Door

At the center of Apple's allegations are two individuals whose trajectories from Apple to OpenAI form the backbone of the complaint. Chang Liu, a senior electrical engineer who spent eight years at Apple, and Tang Yew Tan, a vice president of design for iPhone and Apple Watch who devoted 24 years of his career to the company, are both named as defendants. Tan now serves as OpenAI's chief hardware officer.

According to Apple's complaint, at least two long-time Apple employees who departed for OpenAI allegedly participated in the alleged scheme by emailing themselves internal Apple information before leaving — a low-tech method of corporate intelligence extraction that, if proven, would represent one of the more brazen acts of alleged trade secret theft in the industry's recent memory.

Through these former employees and their privileged access to what Apple describes as "sensitive projects, trusted partner relationships, proprietary manufacturing techniques, and unreleased products," the company claims OpenAI has been able to assemble a detailed picture of Apple's product roadmap and operational methods — intelligence that Apple argues has directly enabled OpenAI's push into consumer hardware.

The Interview Room as an Intelligence Operation

The most startling allegation in Apple's complaint involves what reportedly happens when OpenAI interviews current Apple employees for potential positions. According to the lawsuit, OpenAI interviewers have allegedly instructed prospective hires to bring "actual parts" as "props" from Apple for "show and tell" during their interviews — a recruitment practice that, if accurate, transforms the job interview itself into an intelligence extraction operation.

Apple frames this not as an isolated tactic but as part of a deliberate corporate strategy, alleging that OpenAI has engaged in "a strategy to extract Apple's confidential information" that is "normalized and exemplified by leadership." The language is pointed: this is not, Apple argues, the rogue behavior of a few bad actors. It is, the complaint contends, institutional.

The Jony Ive Connection

The inclusion of io Products as a defendant adds an additional dimension of Silicon Valley intrigue. The company was founded by Jony Ive — the British designer whose aesthetic vision shaped the iPhone, the iMac, the MacBook, and virtually every iconic Apple product of the past three decades. Ive departed Apple in 2019 after nearly 30 years. OpenAI acquired io Products last year, bringing Ive and his design capabilities into the AI company's orbit as it prepares to enter the consumer hardware market.

Apple's lawsuit accuses all parties of "acting in concert and as an enterprise, exploiting Apple's confidential information to advance OpenAI's efforts to enter the consumer hardware market" — a characterization that positions the alleged misconduct not as scattered opportunism, but as a coordinated corporate strategy.

OpenAI is expected to release its first hardware product — described as a type of keyboard designed to interface with its AI tools — later this month. The company is also preparing for a potential initial public offering. Apple's lawsuit argues that OpenAI's "nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets."

From Public Partnership to Federal Court

The lawsuit marks a stunning reversal in what had been one of the most visible corporate alliances in the AI industry. Tim Cook, Apple's outgoing CEO, integrated ChatGPT into Apple devices as the company sought to expand its AI capabilities — a partnership that placed OpenAI's technology in front of hundreds of millions of users worldwide. When Cook announced his retirement in April, OpenAI CEO Sam Altman publicly praised him as "a legend," expressing gratitude for "everything he has done."

The warmth evaporated quickly. This year, Apple began shifting more of its AI features to run on Google's Gemini model and tools — a signal that the relationship with OpenAI was already cooling. The federal lawsuit filed Friday suggests the cooling was driven by something more serious than a strategic preference for a different AI partner.

Apple said it attempted to raise its concerns directly with OpenAI in February 2025, seeking a resolution before resorting to litigation. It was, the company says, ignored.

What Apple Is Asking the Court to Do

The relief Apple is seeking is both immediate and sweeping. The company has asked the court to issue a prohibitory injunction barring OpenAI from obtaining or using any of the allegedly misappropriated confidential information — a remedy that, if granted, could directly interfere with OpenAI's hardware product launch and potentially reshape the company's consumer technology ambitions at a critical moment in its pre-IPO trajectory.

Apple is also seeking unspecified monetary damages, leaving the financial stakes of the litigation to be determined as the case progresses.

What began as a partnership that put the world's most popular AI chatbot on the world's most valuable consumer devices has become a federal lawsuit alleging systematic theft. In Silicon Valley, where talent moves constantly between competitors and information travels with the people who carry it, the Apple-OpenAI collision is a warning shot heard across the entire industry.
