US EditionUS Jury Says Apple Must Pay Masimo $634 Million in Smartwatch Patent Case
The ITC reviews whether Apple Watch’s blood oxygen data display on the paired iPhone violates Masimo’s patent after a new feature redesign launched in August.
- In new filings today, the U.S. International Trade Commission instituted a combined modification and enforcement proceeding to review Apple's redesigned Blood Oxygen feature after a complaint from Masimo, health-technology company.
- After Masimo accused Apple of patent infringement, Apple paused sales and in August redesigned the Blood Oxygen feature for the Series 9, Series 10 and Ultra 2.
- You start a session using the Blood Oxygen feature on your Apple Watch and its sensors collect data, but results appear only in the Respiratory section of the iPhone Health app, raising paired watch+iPhone patent issues.
- The ITC says it expects to make a decision within six months in a proceeding that will address whether Apple's solution should be banned under the Masimo patent dispute, potentially extending the initial import ban.
- Amid a longstanding legal battle, a jury verdict for Masimo escalated the stakes as a California federal jury found Apple infringed Masimo's patent, while Apple plans to appeal and related suits include Masimo's challenge to US Customs and Border Protection.
