Apple Watch Series 9 and Ultra 2 in US face a 2028 wait for blood oxygen feature due to patent dispute with Masimo.

Apple Watch Series 9 and Ultra 2 users in the US may face a 2028 wait for the blood oxygen feature due to a patent dispute with Masimo. Apple was forced to disable pulse oximetry in these models, and the US Customs and Border Protection banned importing them with the feature. Apple disabled the feature through software but can reintroduce it via a future update, pending an appeal or patent expiry in August 2028.
