Judge Vacates Default Against Jon Prosser, Case Moves Into Discovery

The court’s order lets Apple seek testimony and documents to probe who accessed a development iPhone and what was shared.

Overview

  • A federal judge set aside the default that had barred Jon Prosser from responding to Apple’s July 2025 complaint, allowing him to file a formal answer and contest the claims.
  • The order requires Prosser to respond to the complaint and to produce materials and sit for a deposition as part of ordinary discovery procedures.
  • The signed order lists production and deposition deadlines that already passed on the document, a discrepancy that reporters say suggests some discovery activity may already have occurred.
  • Apple’s lawsuit alleges that Michael Ramacciotti accessed Apple engineer Ethan Lipnik’s development iPhone and that Prosser published details from that device about the iOS Liquid Glass redesign, and reporting says Ramacciotti has cooperated with investigators.
  • Prosser has continued publishing Apple-related videos during the litigation, and Apple’s decision to pursue discovery rather than a default judgment could yield sworn testimony, documents, possible damages or injunctive relief and serve as a warning to other leakers.
