The record
Written from the 1 report below. Nothing here is unsourced.
- A US district court has rejected Apple's motions to overturn a $634 million verdict and to get a new trial in its patent dispute with medical technology company Masimo.
- Masimo had sued Apple in 2020, claiming the Apple Watch infringed its patents related to blood oxygen and health monitoring technology, and a jury ruled in Masimo's favour in November 2025.
- The court found the Apple Watch falls within the patent's scope, so the jury's verdict stands.
- Earlier, in 2023, the US International Trade Commission had blocked imports of some Apple Watch models over the same dispute, leading Apple to sell certain models in the US without the blood oxygen feature.
- The ruling does not directly affect current Apple Watch users, and Apple says it will appeal.
What to watch next
- Whether Apple files an appeal, as it has said it will, arguing the disputed patent expired in 2022 and other Masimo patents were already invalidated.
- Any new court orders in the ongoing legal battle that could affect future Apple Watch models.
- Whether the blood oxygen feature's availability in the US changes further following the verdict.
