Apple Watch users can breathe easier again. Or at least measure their blood oxygen levels with their Apple Watches.

Apple today announced that an update to Apple Watches and iPhones (16.1) to be released today will bring a redesigned Blood Oxygen feature for those with the Series 9, Series 10, and Apple Watch Ultra 2 users.
This comes after a long legal fight with Masimo, a health technology company, over a patent dispute that required Apple to deactivate the feature on Apple Watches in the U.S. that included the feature. Apple had to stop selling Apple Watches without the feature intact, but got a pause on that import ban for the Christmas season in 2023.
The patent case is still under appeal by Apple, but Apple is saying that the move comes after a U.S. Customs ruling that allows Apple to once again import Apple Watches with the Blood Oxygen feature.
I may be speculating, (I doubt it) but it sounds like a friends in high places who like gifts moment to me.
