check blood oxygen with Apple Watch

The Apple Watch Series 9 and Apple Watch Ultra 2 are embroiled in an ongoing ITC situation, which briefly barred the devices from being sold in the United States last month. This comes after the ITC ruled that the Apple Watch’s blood oxygen sensor infringes on two patents held by medical device company Masimo.

As it stands right now, Apple is still selling the Apple Watch Series 9 and Ultra 2 in the United States, but with the blood oxygen features disabled due to the ITC ruling.

Can I still buy an Apple Watch with blood oxygen features from other retailers?

Yes, for the time being, you can still buy an Apple Watch Series 9 and Apple Watch Ultra 2 from third-party retailers like Best Buy and Amazon, and they will still have the blood oxygen app and features.

The ITC’s decision only impacts Apple’s ability to sell the Series 9 and Ultra 2 via its online store and retail stores.

April 6, 2024:

Apple is still selling a redesigned version of the Apple Watch Series 9 and Apple Watch Ultra 2 with the blood oxygen sensor disabled. As the Masimo case continues to progress with the ITC system, Apple has filed a new 900-page brief calling on the import ban to be overturned.

The International Trade Commission exceeded its statutory authority by issuing an injunction in a case where the requisite “domestic industry” was non- existent. The Commission compounded that fundamental error by issuing a series of substantively defective patent rulings. Apple respectfully submits that this Court should correct the Commission’s errors and ensure the agency observes the jurisdictional limitations Congress prescribed.

Apple officially begins selling the Apple Watch Series 9 and Ultra 2 without the blood oxygen features. This change does not impact anyone who already owns an Apple Watch with the blood oxygen features. It also only applies in the United States. 

“Apple Watch Series 9 and Ultra 2 no longer include the Blood Oxygen feature,” reads the banner applied to the checkout flow for both model watches on Apple’s website.

Apple continues its appeal of the initial ITC ruling. The company says this process could take over a year. It’s unclear if any interim solution will be reached that allows Apple to begin selling the Apple Watch Series 9 and Ultra 2 with the blood oxygen features.

The US appeals court denies Apple’s request to pause the ban for the duration of its appeal of the ITC’s ruling. The US appeals court says Apple Watch Series 9 and Apple Watch Ultra 2 with blood oxygen features will be banned from sale in the United States again, effective 5:00 pm ET on January 18, 2024.

Apple responds and says it will continue selling the devices with the blood oxygen features disabled.

January 15, 2024:

U.S. Customs and Border Protection rules that Apple’s redesign falls outside the scope of the ITC ruling. Apple’s redesign, however, is to remove the pulse oximetry features from newly sold devices.

This means that U.S. Customs has found the Apple Watch Series 9 and Ultra 2 do not infringe on Masimo patents so long as they don’t “contain pulse oximetry features.”

For now, Apple will continue to sell the Apple Watch Series 9 and Apple Watch Ultra 2 with pulse oximetry features. Meanwhile, we still await the decision from the US appeals court on Apple’s request to pause the Apple Watch ban throughout the entire duration of the appeals process.
