Apple has moved to avoid a U.S. import ban impacting the Apple Watch Series 9 and Ultra 2 caused by a patent dispute with California firm Masimo.

A letter from Masimo to an appeals court judge dated January 15 said that the tech giant could avoid a recently instated import ban on the Apple Watch Series 9 and Ultra 2 by removing the blood oxygen app from these Apple Watches.

In the letter, Masimo says that U.S. Customs and Border Protection (CBP) decided that Apple’s redesign falls outside the scope of the International Trade Commission’s (ITC) import ban on the two devices.

It added that Apple had explained that its “redesigned Watch products definitively do not contain pulse oximetry functionality.”

A decision from the U.S. Federal Appeals Court regarding Apple’s request to pause any U.S. ban on the two smartwatch models during the appeals process could come as early as Tuesday.

Masimo said in a widely reported statement on Monday that Apple’s decision to remove the tool from its smartwatches was “a positive step toward accountability,” adding: “It is especially important that one of the world’s largest and most powerful companies respects the intellectual property rights of smaller companies and complies with ITC orders when it is caught infringing.”

Apple has yet to comment publicly on Monday’s development.

The watches were banned in the U.S. toward the end of last year after the ITC ruled that the blood oxygen sensors violated patents belonging to Masimo.

Apple removed the devices from stores shortly before the ban took effect on December 26, but almost immediately, it won an appeal to resume sales temporarily.

Apple tipster Mark Gurman claimed on Monday that Apple is preparing a software update that will adjust the blood oxygen app’s algorithms in a bid to put some space between it and Masimo’s patented technology.

Gurman also said that Apple has already started shipping these modified Series 9 and Ultra 2 smartwatches to Apple Stores, though it’s not certain when they will be available for purchase.

The blood oxygen feature, which measures the saturation of oxygen in the user’s red blood cells, is expected to continue functioning on Series 9 and Ultra 2 devices that have already been sold, and it’s likely to remain on watches sold outside of the U.S.

There are still many moving parts in the dispute between Apple and Masimo, suggesting that it still has some way to run.

High blood pressure monitoring may finally come to the Apple Watch in 2025
The Apple Watch Ultra 2 on someone's wrist.

The Apple Watch is no longer just a smart wearable that doubles as a status symbol. The wrist-based powerhouse is capable of saving lives thanks to a bevy of different features, but there's one area — blood pressure readings — that Apple has never been able to crack. Now, a new rumor hints that the necessary sensors could come to the Apple Watch Series 11 and the Apple Watch Ultra 3.

It's a technology that Apple has tried to crack for a while now, but Mark Gurman said in his Power On! newsletter that we might see blood pressure sensors in the next iteration of the Apple Watch. Based on these early reports, the Apple Watch Series 11 and Ultra 3 will be able to alert users when their blood pressure is too high.

I tracked my sleep with a smart display, ring, and watch. This is my favorite

Since I had a heart attack four years ago, I’ve been on a journey to understand my health. A crucial part of my recovery and focus has been my sleep, and it'smade even more important by the fact that my heart attack took place in the middle of the night while I was fast asleep. Thankfully, I woke up, but our sleep can tell us a lot about our underlying health.

Virtually every wearable now offers some form of sleep tracking, but like most things in technology, not all devices are created equal. Beyond just data, there’s also the question of which is most comfortable to track your sleep, which device gives you the most reliable data, and ultimately, how you can ensure you track your sleep wherever you are.
