A U.S. trade tribunal preliminarily ruled that Apple's current Apple Watches do not infringe patents owned by Masimo MASI. This decision comes after Apple changed its watches to avoid an import ban imposed by the International Trade Commission in 2023. The full commission will decide whether to affirm the decision. The ruling comes as part of a multi-front patent dispute between Apple and Masimo, who have accused Apple of stealing their pulse-oximetry innovations.
