For the record, the R'ster abandoned most of the IP that he disclosed to IH. Why? I say because it didn't work - a point that he has proven by his actions on top of his abandonment.
True, Rossi did abandon his one "Rossi Effect", or LENR IP. That leaves the one true patent he has left, the "Fluid Heater". It was patented only as a fluid heater, although Rossi listed his energy catalyzer (Ecat) as one of the many fuels it could run on. There was a reason he slipped it in there, as you can see from his website: https://ecat.com/ where he claims this:
"The patent covers the ECAT as a Fluid Heater based on the Rossi Effect in all its details. Since the Rossi Effect is the main source of energy of the ECAT, this means that the ECAT Core Technology is protected by this patent. The Rossi Effect is based on the exothermal reaction between Lithium and Hydrogen which is catalyzed by Nickel or any other Group 10 elements in the Periodic Table, including Palladium and Platinum. The Rossi Effect is a new type of high energy density LENR based exothermal process discovered by Andrea Rossi."
So basically he is trying to piggy back his Ecat, onto his legitimate Fluid Heater patent, and claim both are protected IP. I am no expert, but I would guess it has little chance of holding up against a challenge, and he probably knows that. But he has it there for a purpose, and that is probably to extort the first company to market an LENR product.
Something for your team to be aware of.
