Friday, September 18, 2020

IRVINE, Calif. - Masimo has filed a legal complaint in the U.S. District Court for the Central District of California claiming Apple infringes on 10 of its patents with its Apple Watch, according to news reports. The complaint charges Apple with stealing trade secrets by hiring key personnel from Masimo, including Michael O’Reilly, its former chief medical officer and executive vice president for medical affairs. Masimo claims the Apple Watch, including the Series 4 and 5 models, uses technology covered by its patents related to heart rate monitoring and other capabilities. Masimo has developed non-invasive physiological monitoring techniques to track pulse rate, arterial oxygen saturation and other parameters using transmitted light. Apple announced this week that its Apple Watch can now track blood oxygen.
