Apple has filed a blockbuster lawsuit against OpenAI, accusing the AI company of systematically stealing confidential information to jumpstart its hardware division. The complaint landed Friday in federal court in California, naming two former Apple employees and multiple OpenAI entities as defendants. Therefore, what began as a partnership has now escalated into open legal warfare between two of Silicon Valley’s most powerful players.
The defendants are Chang Liu and Tang Yew Tan, both senior Apple veterans who defected to OpenAI. Liu worked as a senior system electrical engineer before joining the AI company. Tan held even higher ground—he was a vice president at Apple involved in designing the iPhone, Apple Watch, and iPod. Now Tan serves as OpenAI’s chief hardware officer.
Apple’s 41-page complaint alleges a coordinated campaign to extract confidential information. The lawsuit claims OpenAI actively encouraged Apple employees it was recruiting to discuss secret projects and share protected hardware details. Worse, according to Apple, some candidates received guidance on how to avoid drawing scrutiny during the recruitment process.
Chang Liu’s alleged conduct stands out for its brazenness. Apple says he refused to return his company-issued laptop after leaving. Furthermore, he later exploited an authentication flaw to breach Apple’s internal network. The lawsuit claims he downloaded dozens of confidential files related to hardware development—work he had been trusted with during his tenure.
Tang Yew Tan’s alleged actions followed a similar pattern. Apple says he emailed himself supplier information and internal industry reports before departing the company. Additionally, the lawsuit alleges Tan encouraged other Apple employees to bring physical components and discuss confidential projects during OpenAI job interviews.
OpenAI acquired io Products last year as a launching pad for consumer AI hardware. The startup was co-founded by Jony Ive, the legendary Apple design chief, along with Tan and others. The company has remained deliberately vague about what device it plans to release. Instead, it describes the project as simply a new way of interacting with artificial intelligence beyond traditional products.
Apple contends that OpenAI’s hardware development partly relies on stolen designs, manufacturing knowledge, and supply-chain intelligence taken directly from Apple. That accusation carries serious weight. These are precisely the competitive advantages that keep Apple ahead in hardware innovation.
The lawsuit marks a stunning reversal in relations between the two companies. Just months ago, Apple and OpenAI worked together seamlessly. Siri integrated ChatGPT into Apple devices, directing certain requests to OpenAI’s chatbot. Apple users got direct access to ChatGPT through Apple’s software.
However, OpenAI’s pivot into consumer hardware created direct competition. The partnership that once thrived began deteriorating rapidly. Apple claims it contacted OpenAI in February after discovering possible information leaks. According to the company, OpenAI never responded.
Apple is seeking damages and a court order barring the defendants from using its alleged trade secrets. The company appears determined to send a clear message to Silicon Valley about the costs of misappropriating confidential information. Meanwhile, OpenAI maintains it has no interest in stealing anyone’s trade secrets.
These allegations remain unproven in court. Still, the lawsuit sets up a major legal battle that will likely expose tensions between ambition and ethics in the AI industry. Finally, the case demonstrates how rapidly alliances can collapse when business strategies collide in Silicon Valley.
