Apple to halt Apple Watch Series 9 and Apple Watch Ultra 2 sales in the US this week due to Masimo dispute

The move comes following an ITC ruling as part of a long-running patent dispute between Apple and medical technology company Masimo around the Apple Watch’s blood oxygen sensor technology.

The Apple Watch Ultra 2 and Apple Watch Series 9 will no longer be available to order from Apple’s website in the U.S. after 3 p.m. ET on Thursday, December 21. In-store inventory will no longer be available from Apple retail locations after December 24.
