Apple Files Lawsuit Against Jon Prosser Over Alleged iOS 19 Trade Secret Leaks

Apple has initiated a significant lawsuit in the Northern District of California, targeting prominent tech leaker Jon Prosser and Michael Ramacciotti. The tech giant accuses the pair of misappropriating trade secrets and violating the Computer Fraud and Abuse Act, stemming from alleged leaks concerning the unreleased iOS 19 operating system.
According to the lawsuit, the core of the complaint asserts that Michael Ramacciotti, reportedly at Jon Prosser’s instigation, illegally accessed an Apple employee’s Development iPhone. This unauthorized access allegedly allowed the theft of confidential information related to iOS 19, which Prosser then purportedly used for content on his YouTube channel, generating ad revenue.
Apple claims Ramacciotti gained access by tracking the employee’s movements, obtaining their passcode, and breaking into the device. He then allegedly made a video call to Prosser, demonstrating confidential iOS 19 features, which Prosser is accused of recording and disseminating. The company notes that early leaks, which began as far back as January and included details like the “Liquid Glass overhaul,” were directionally accurate despite being based on work-in-progress material.
The Cupertino firm is seeking a jury trial, demanding injunctive relief to prevent further disclosure of its confidential information, unspecified damages, punitive damages for willful misappropriation, and coverage of its attorneys’ fees. Apple also seeks an order directing the defendants to return or destroy any remaining confidential material.
In a public response on X (formerly Twitter), Jon Prosser has disputed Apple’s version of events, offering his own account of how he obtained the iOS 19 interface. This unfolding legal battle underscores Apple’s stringent efforts to protect its intellectual property, with more details expected to emerge as the case progresses.
