Apple advances in legal battle against OpenAI as court expands discovery scope

On October 28, 2026, IT Home reported that Apple has made progress in its legal case against OpenAI. A judge has approved Apple's request to expand the scope of discovery in the case. Apple is suing OpenAI, io Products, and two former employees, Chang Liu and Tang Tan, for allegedly stealing trade secrets. The court has allowed Apple to access certain internal documents, evidence, and employee testimonies, including Chang Liu's usage records for ChatGPT, Claude, and Codex, as well as devices used to access and store Apple's confidential information. The court did not grant Apple's full request, such as detailed information on OpenAI's own devices and accounts. Defendants have 14 days to submit records and respond to Apple's questions. The case involves allegations related to battery technology, power management, and surface treatment of metals. The court's decision marks a significant step in the legal proceedings, highlighting the ongoing tensions between Apple and OpenAI over intellectual property and trade secrets.
