Jury Awards Masimo $634 Million in Apple Watch Blood-Oxygen Patent Case

A separate ITC review could still affect Apple Watch imports.

Overview

  • A California federal jury found Apple infringed U.S. Patent No. 10,433,776 covering low-power pulse oximetry, which expired in 2022.
  • Jurors determined the Apple Watch qualifies as a "patient monitor" and based damages on roughly 43 million devices.
  • The award aligns with Masimo’s requested range after Apple urged the court to limit damages to $3 million to $6 million.
  • Apple said it will appeal, calling the case reliant on expired, decades-old technology and noting many Masimo claims were found invalid.
  • In a separate track, the ITC has reopened a review of Apple’s redesigned blood-oxygen implementation, leaving potential import restrictions in play.
