Masimo is not a sham company selling sham products.  Admittedly, they consumer products are pretty limited, but, as a hospital-based physician, I see their products ALL THE TIME in the hospital. Specifically, they make physiological monitors that are extensively used in ICUs, operating rooms and ERs.  In the mid-90s, Masimo introduced software / algorithms that reduced error due to motion artifact or low flow states.  It really revolutionized the use of pulse oximetry and allowed it to be used outside the OR and ICU settings (where patients are typically still) and into more ambulatory settings such as ERs, ambulances, clinics, etc.

I have no idea about the merits of this case, but Masimo is certainly not a patent troll. They did about $1.24 billion in revenues last year (about $125M in profits).  Compared to Apple, they are certainly a "small" company.

You’re more comfortable using a $10 pulse oximeter from Amazon that was probably made in the same factory that makes 1,000 other unrelated products?  Good luck to you. 

I don't know much about the specific allegations surrounding the watch and the suit. However, finger pulse oximeters sample the blood through the fingernail and underlying skin -- which is pigment free (unless you use fingernail polish). Therefore, fingertip pulse oximeters are not influenced by skin pigmentation.
