I’m not sure it’s very technologically complex though. Seems like the patent just covers the positioning of a few sensors. It’s about as silly as allowing “multitouch” to be patented…
It's not about just any blood oxigen measuring tech, there's various ways you can do it and apparently Apple's newest watch is implementing a very accurate technique developed by Masimo.
Those $20 devices exist because measuring blood oxygen accurately via light refracted through flesh is way easier than via light reflect off the flesh(especially as you move around), which is what this fight is all about.

Or, you know, pay for it? It's not like Apple is scrapping for change behind the couch cushions.
