A federal jury in the United States District Court for the Central District of California formally ordered Apple to pay Masimo Corporation $634 million in damages after finding that certain Apple Watch features—including workout modes and heart rate notifications—infringed upon Masimo's foundational pulse-oximetry and blood oxygen monitoring patents. Although Apple strongly disagreed with the verdict and stated its intention to pursue appeals, the multi-million-dollar jury decision marked a landmark legal outcome in the ongoing corporate battle.
