Apple Inc. now faces a staggering $634 million judgment after a California federal jury found the tech giant infringed on Masimo’s patent regarding blood oxygen monitoring technology.
Landmark Intellectual Property Ruling
The verdict, reported by Reuters, centers on the Apple Watch’s workout and heart rate notification features, which the jury determined unlawfully incorporated Masimo’s patented pulse oximetry innovations. According to Masimo, a leader in medical device technology (Masimo), this legal win is a critical measure to safeguard their technological advancements that directly benefit patient care.

Strategic Implications For Apple
An Apple spokesperson noted plans to appeal the decision, contesting that the patent in question expired in 2022 and dated back to outdated patient monitoring methods. This response underscores a broader debate over legacy technologies versus evolving innovation paradigms.
Broader Context Of The Dispute
The contentious legal battle extends beyond patent infringement alone. Masimo has previously accused Apple of recruiting its talent, including the company’s chief medical officer, to leverage its pulse oximetry expertise. The United States International Trade Commission further bolstered Masimo’s stance in 2023 by banning Apple from importing devices featuring blood oxygen monitoring capabilities—a cautionary precedent that has prompted Apple to re-engineer the function to operate on the paired iPhone rather than the watch.
Counterlitigation And Ongoing Legal Challenges
As the litigation landscape evolves, Masimo is also challenging U.S. Customs and Border Patrol for approving the new Apple Watch imports, while Apple has escalated its contest to higher courts, seeking reversal of the import ban. In a related development, Apple secured a $250 statutory minimum in a countersuit after a jury found Masimo had infringed on its design patents.
This case not only highlights the high stakes involved in protecting intellectual property but also reflects the broader tensions at the intersection of innovation, talent acquisition, and competitive market dynamics in the technology sector.
