Overview
- Apple is reintroducing its blood oxygen monitoring feature to select Apple Watch models, including Series 9 and Ultra 2, through a software update after a patent dispute with Masimo.
- The reintroduction allows Apple Watch users to access the redesigned blood oxygen feature by updating their iPhone to iOS 18.6.1 and their Apple Watch to watchOS 11.6.1.
- The updated feature involves sensor data being measured on the Apple Watch but calculated on the paired iPhone, with results viewable in the Health app's Respiratory section.
- Apple had previously removed the blood oxygen monitoring feature from its watches due to a patent infringement ruling, but has now reintroduced a non-infringing version.
- This software update primarily affects watches in the US market; devices purchased before 2024 or outside the US, which were not subject to the import ban, will not experience changes.

FAQ
The dispute centered on Masimo accusing Apple of infringing its patented pulse oximetry technology used for blood oxygen monitoring on the Apple Watch, including employee poaching and patent infringement claims.
Apple disabled the blood oxygen monitoring feature through a software redesign to avoid infringement, reintroduced a non-infringing version via a software update for certain models, and is working on hardware redesigns to completely circumvent Masimo's patents.
The U.S. import ban applies primarily to the Apple Watch Series 9 and Ultra 2 models that infringe Masimo's patents, with devices bought before 2024 or outside the U.S. not affected by the ban.
No, the feature was temporarily disabled due to the patent ruling but has been reintroduced in a redesigned, non-infringing software version on select Apple Watch models via updates to iOS and watchOS.
