See image. Adds an incredible amount of context to this patent.
Best I can tell, the post on Hacker News on April 27th, 2019 brought this patent to the surface.
100% agree. Let me make a Salvatore Pais summary post, since I've followed this situation closely and know the important sources.

You'll get a single PDF containing all information on that patent. This includes papers submitted as theoretical justification.
It's quite odd. The Sheehy letter claims we need the patents because China is rapidly advancing in the space.
Another person to look into is Harold "Sonny" White. Here's a remarkable paper by him: https://anonfile.com/h7ffxbu1oe/white2015_pdf
