That brings the total to about $818 million, before any post-judgment interest is added.<\/p>\n\n<p class=\"wp-block-paragraph\">Selna said Masimo should receive the <strong>extra money<\/strong> because it was denied royalty payments during the infringement period. He rejected Apple\u2019s argument against interest. Masimo had asked for about $243 million at 7 percent, but the court used Masimo\u2019s borrowing rate instead, with annual compounding starting from the beginning of the infringement.<\/p>\n\n<p class=\"wp-block-paragraph\">For people who follow Apple Watch legal battles, this comes out of the <strong>November 2025 jury verdict<\/strong> in California. That jury found that Apple Watch features, including heart-rate notifications, infringed Masimo\u2019s U.S. Patent No. 10,433,776, a patent tied to pulse oximetry. The original $634 million award came from that verdict.<\/p>\n\n<p class=\"wp-block-paragraph\">If you own an Apple Watch, the practical point is pretty narrow. This applies to <strong>past sales only<\/strong>, because Masimo\u2019s patent expired in June 2022. The verdict doesn\u2019t shut down the heart-rate features on current watches.<\/p>\n\n<p class=\"wp-block-paragraph\">Apple already tried to overturn the award, or at least reduce it. Selna upheld it in July, and Apple is still <strong>appealing<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">This also isn\u2019t the whole fight. It\u2019s one piece of a broader dispute that started in 2020, with a <a href=\"https:\/\/en.softonic.com\/articles\/the-sale-of-the-apple-watch-is-in-danger-in-the-united-states-what-is-happening\" rel=\"noopener\">late-2023 U.S. International Trade Commission import ban<\/a> affecting some Apple Watch models, temporary <strong>sales pauses<\/strong> in the U.S., blood oxygen workarounds on newer devices, and claims that Apple hired Masimo employees and drew on Masimo\u2019s wearable health expertise.<\/p>","protected":false},"excerpt":{"rendered":"<p>In the Masimo patent case, Judge James Selna has ordered Apple to pay another $184 million in prejudgment interest.
