ITC Judge Says Some Apple Watch Models Infringe Blood Oxygen Patents

Certain models of the Apple Watch infringe one of five Masimo Corp. patents related to using light sensors to measure the amount of oxygen in the blood, a US International Trade Commission judge found in the first round of Masimo’s bid to block imports of Apple Inc.'s popular smartwatch. The ITC had postponed the decision three times before Judge Monica Bhattacharyya issued her initial determination, announced in a notice.
