A judge in Washington, D.C., ruled Tuesday that Apple infringes on one of medical device maker Masimo’s patents for light-based pulse oximetry sensor functionality and components used in Apple Watch 6 onward. The sensor measures blood oxygen levels.
Next the U.S. International Trade Commission (ITC) will decide whether to ban imports of Apple Watches that include the sensor, Masimo said.
In a statement, Apple disputed the ruling.
