It's worth to read the detailed case. Masimo is not a small company coming out of nowhere to capitalize from Apple, they're a decades-old medical equipment company. The case outlines how Apple met with them in 2013 to discuss collaboration. After that meeting, Apple apparently hired away several key-members of Masimo with knowledge about their non-invasive biometric monitoring tech, including their "Chief Medical Officer and EVP for Medical Affairs", who already joined Apple in that same year... The case claims violation of various patents for non-invasive blood data-collection via LEDs of specific wavelengths and photo-diodes in a specific geometry, patents to reduce power consumption of pulse oximeters as well as patents to detect when a pulse oximeter probe is misaligned on a patient. But most of all, they can demonstrate in the evolution of the Apple Watch how Apple launched their initial generation without such optimizations but found them to be necessary later-on, so it seems Masimo's patents are not that obvious.
