Apple Reintroduces Blood Oxygen Monitoring to Apple Watch After Patent Dispute
Apple is reintroducing its redesigned blood oxygen monitoring feature to select Apple Watch models via a software update, following a patent dispute with digital health company Masimo.
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.
