Apple on Friday filed a lawsuit against OpenAI and two former employees, alleging misappropriation of the iPhone maker’s trade secrets to benefit the ChatGPT-owner’s foray into consumer hardware.
The complaint, filed in the US district court for the Northern District of California, alleges a co-ordinated effort to steal Apple’s confidential information, including product designs, manufacturing processes and supply chain strategies.
The lawsuit is against former senior system electrical engineer of Apple Chang Liu and former vice president of product design for iPhone and Apple Watch Tang Yew Tan, as well as OpenAI Foundation, OpenAI Group PBC and io Products.
It dramatically escalates tension between Apple and the ChatGPT maker that has been simmering for months. OpenAI did not immediately respond to a Reuters request for comment.

Apple alleged that Liu had failed to return a company-issued work laptop and later used an authentication bug to access Apple’s internal network, down “dozens of Apple’s confidential hardware-related files”.
The company also claimed that Tan “has been methodically using Apple’s confidential information to benefit OpenAI” by e-mailing himself information about Apple suppliers and internal industry summaries before his departure.
A person familiar with the matter told Reuters in May that OpenAI was exploring legal options against Apple, including notifying the technology giant of a breach of contract but potentially not filing a full lawsuit.
The tensions between the two tech companies have strained their relationship and shown how the race to develop AI products has intensified competition for talent and proprietary technology.
In 2024, Apple announced integration of its “Apple Intelligence” technology across its apps including Siri and brought OpenAI’s chatbot ChatGPT to its devices.
Their partnership allows users to access ChatGPT results through Siri, while iPhone users can also sign up for ChatGPT memberships directly from the iOS settings menu.
OpenAI bought hardware start-up io Products, founded by former Apple designer Jony Ive, last year in a $6.5 billion deal, underscoring its push to move beyond software into consumer hardware. Ive is not named in the lawsuit.
Last month, Apple rolled out a long-delayed overhaul of Siri. The update comes two years after Apple first promised major upgrades that were repeatedly delayed. – Reuters
