Apple is disabling the blood oxygen monitoring feature on its latest Apple Watch models to comply with legal requirements amid an ongoing court dispute with Masimo. The altered Apple Watch Series 9 and Ultra 2, which were initially released in September, will be available for purchase starting Thursday. The company is involved in an intellectual property dispute with medical device company Masimo, who claims Apple infringed on its patents for blood oxygen sensors. In October, the US International Trade Commission found Apple violated Masimo's patents and issued an import ban, but Apple received a temporary reprieve.
