"Apple Faces Legal Challenges Over Apple Watch Features and Imports"
Apple has updated its U.S. website to inform customers that the Blood Oxygen feature is no longer included in the Apple Watch Series 9 and Ultra 2 models, with part numbers ending in LW/A. This change is in response to a U.S. International Trade Commission (ITC) sales ban after ruling that Apple violated Masimo's patents with the feature. The Blood Oxygen app still works on previously-sold models, and the feature remains available on Apple Watch models sold outside the U.S. Apple's appeal against the ITC's decision is ongoing.
