Apple has initiated a major legal battle against OpenAI, filing a lawsuit in a U.S. federal court that accuses the artificial intelligence firm of systematically stealing trade secrets to accelerate its own hardware development. The complaint, filed in mid-July 2026, alleges that OpenAI engaged in a pattern of misconduct, including the recruitment of Apple employees to gather confidential information about unreleased products, manufacturing processes, and proprietary technologies. Apple claims that this activity was not merely competitive hiring but a coordinated effort to gain an unfair advantage in the consumer hardware market.
The lawsuit specifically names two former Apple engineers, Tang Yew Tan and Chang Liu, who now hold key roles at OpenAI. According to the filing, these individuals allegedly bypassed security protocols, retained confidential documents after leaving the company, and even coached other prospective hires on how to extract sensitive data during the interview process. Apple asserts that OpenAI’s nascent hardware business, which is reportedly exploring new ways to integrate AI into physical devices, is built upon this misappropriated intellectual property.
This legal action marks a significant rupture in the relationship between the two tech giants. Just two years ago, the companies announced a high-profile partnership to integrate ChatGPT into Apple’s ecosystem, including Siri and other core applications. That collaboration now appears to be in jeopardy as Apple seeks to protect its internal research and development efforts. The lawsuit includes claims regarding the misuse of secret project names, physical hardware components, and even Apple’s specialized metal-finishing techniques.
OpenAI has denied the allegations, with a spokesperson stating that the company has no interest in the trade secrets of other firms and remains focused on building innovative technology. As the case moves forward, the legal proceedings are expected to shed light on the extent of the alleged data theft and the potential impact on OpenAI’s future product roadmap. For the public, the dispute highlights the intensifying competition in the AI hardware sector and the high stakes involved in protecting proprietary innovation.
