SAN FRANCISCO – Apple will be banned from selling watches with blood oxygen sensors beginning Thursday in the United States, the US Court of Appeals for the Federal Circuit said on Wednesday.

The ban stems from an intellectual property dispute with Masimo, a medical device company. 

In October, the International Trade Commission found that Apple's blood oxygen sensors had infringed on Masimo's intellectual property.

The ban prevents Apple from importing the devices in question, which involve the Apple Watch Series 9 and Ultra 2.

In December, Apple briefly removed the affected watches from its online and retail stores, while retailers with those devices in stock may still sell them.
