A world that did not allow patent trolls like Myrvold to exist would be a better place. Patents don’t seem important or necessary until someone goes after you for patent infringement.
That said, it seems reasonable that someone who invents a novel product and actually takes it into production might be afforded some kind of protection. There should be a rational middle ground, but it’s not found in the current system.

Jordi’s example on DIYdrones shows $PTMK220 and $PTMK251 commands that aren’t in the Etek document you referenced, though $PTMK314 is shown.
Is there a programmer reference or user manual that defines the $PMTK configuration strings for LS20031 ?
