Apple has recently updated its Oximeter patent, which could mean that U.S. users could get access to the feature once more.
Back in December 2023, a patent dispute arose between Masimo and Apple about the Oxygen sensor in two of the best Apple Watch models, the Apple Watch Series 9 and Apple Watch Ultra 2. This led to the wearables being temporarily pulled from sale in the U.S. However, Apple quickly updated them through a software update so that the blood oxygen sensors were disabled.
