Apple said Thursday that it is updating its watches with a redesigned blood oxygen feature after a recent U.S. customs ruling. The software update will go out to the Apple Watch Series 9, Series 10 and Ultra 2 devices on Thursday.

Apple had to disable its original blood oxygen feature after the U.S. International Trade Commission issued a limited exclusion order in 2023, finding that Apple had violated some of Masimo’s patents. Masimo, which makes pulse oximeters and other patient monitoring devices, has been in an ongoing patent battle with Apple.
