Do a Youtube search on Tom Valone. He worked in the US patent office and has seen the patens get bought up or sequestered by the US government on grounds of national security.
In your post 11 you emphatically state “oil oligarchy, which has bought up and sequestered literally hundreds of patents “. Now which is it, big oil or big gubmit?
Somehow your switcheroo when questioned, lends little confidence in your conspiracy claim.
National security could be a legitimate reason, but without knowing which patents were hidden, its hard to know.
