On November 14, 2025 (local time), a federal jury in California, the United States, handed down a ruling stating that Apple Inc. had violated the oxygen saturation measurement patents held by medical monitoring technology firm Masimo. The infringement mainly pertained to the exercise mode and heart - rate notification functions of the Apple Watch. Consequently, Apple was mandated to pay Masimo a hefty sum of $634 million in damages.

Apple voiced its strong disagreement with the jury's decision and promptly announced its intention to file an appeal. In contrast, Masimo hailed the ruling as a momentous triumph in safeguarding its innovative achievements and intellectual property rights.
