Apple Forced to Halt Sales of Latest Smartwatches After Patent Loss

Apple will stop selling its latest smartwatches, including the Apple Watch Series 9 and Ultra 2, in the US due to a patent dispute with Masimo Corp. The International Trade Commission ruled that Apple violated Masimo's patents related to blood oxygen saturation measurement. The sales halt will impact Apple's core product line during the holiday season, potentially affecting its first-quarter revenue. Apple plans to appeal the decision and believes the ruling is erroneous. The watches will still be available through third-party retailers.
