Mantra has no patents issued in the US. For anything.
And FYI to all you longs, There is already a utility patent issued in the US for the Electrochemical reduction of CO2 to Formic Acid and it isnt OWNED by Mantra.
Oh, and a small company called Texaco also has a US patent for a process of reducing carbon dioxide to at least one useful product including formic acid, and it was issued in 1985. Patent number 4,523,981
Excellent, thanks to all for responding to my ignorance about something I should be on top of. My question arrose from a post earlier in the day from another poster. I had assumed that Mantra had patents for their technology in the US.
