Regarding the last image of a Rossi patent application; one of the things that sold me on Rossi early on, was how active he was with his patent process. Scammers generally do not focus on that kind of mundane stuff, and instead concentrate on the bigger issues. But there was Rossi going to battle to get his own patent's through the process (hugely unsuccessful), but also incessantly attacking his main competitors (Piantelli) EU patent. In fact, just recently, Rossi's efforts led to the EU patent office reversing course to deny Piantelli's already approved patent.
Go figure.
