• How it bears: confirms the patent number on the Institute's 2019 site. The 2018 transfer of the patent from NASA to Richard Eskridge falls in the months the Institute and HoloChron were being set up (HoloChron LLC formed 16 Jul 2018; SAM registration of the Institute 17 Dec 2018, per the Sentinel article). The assignment record (reel/frame) at USPTO would show the terms; not checked. The patent concerns plasmoid electric propulsion, not gravity modification.
