Your main point seems to hinge on patent validity. I have tried to no avail, for years, to teach that patent validity has nothing to do with need, value, efficacy, current workability and most especially not, infringement. When a patent becomes a patent, it's valid, period......until and unless someone challenges it and it's found to no longer be valid. ALL PATENTS ARE VALID!!! otherwise they wouldn't be a patent. A stack of IPR "wins" 8 miles high would not ensure infringement and would not mean a guarantee a given patent can do anything it claims.......... BUT IT'S STILL VALID!
