The iPhone maker accuses OpenAI of deliberately stealing confidential information about unreleased products through poached employees.

Apple has filed suit against OpenAI in a California federal court, alleging a "coordinated campaign" to steal trade secrets, Bloomberg reports. OpenAI allegedly pushed Apple employees to share information, components, drawings, and other materials tied to unreleased products.

"At every level, from members of its technical staff to its chief hardware officer, and in coordination with business partners, OpenAI has been stealing Apple's trade secrets and confidential information," the complaint states. "As a natural result, OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets."

OpenAI denied the allegations. A spokesperson said the company has no interest in others' trade secrets and is focused on building its own technology.
