Following the latest legal defeat in Apple's ongoing patent infringement fight over blood oxygen sensors, the company is set to remove its blood oxygen measurement feature from its Watch Series 9 and Watch Ultra 2 sold in the U.S. The decision comes after the U.S. Court of Appeals for the Federal Circuit declined to extend a pause on an import ban imposed by the U.S. International Trade Commission (USITC) last year, making way for the ban to finally take effect.
The legal setback stems from a ruling that Apple's watches infringed on patents related to blood oxygen measurement that belong to Masimo, which sued Apple in 2020. The U.S. Court of Appeals' decision means that Apple must stop selling watches with this feature while the appeal, which could last a year or more, is in progress.
