Islam, that generally relate to a “personal device”/wearable using “optical beams”/“near infrared lasers” for measurement. At issue are several models of Apple’s Watch product, including Series 1, Series 2, Series 3 GPS, and Series 3 GPS + Cellular watches, which Omni MedSci alleges measure heart rate using semiconductor LEDs.
