Apple’s ongoing patent dispute with health company Masimo over the blood oxygen feature in the Apple Watch Series 9 and Apple Watch Ultra 2, the company’s best Apple Watch models, has thrown up another potential wrinkle for users who already own either device.
In mid-January, Apple was forced to disable the blood oxygen monitoring feature in both of its flagship Apple Watch models after a court denied Apple’s request to halt a ban on sales and imports of the offending models, issued by the U.S. International Trade Commission.
