Rossi has claimed somewhat recently that [lexicon]IH[/lexicon] is a licensee for the Americas and a few other countries. So clearly they haven't acquired the IP. Just the rights to commercialize the e-cat in some regions of the world.
Chances are Rossi is very protective of his secrets with his licensees, given the Defkalion debacle.
I believe the 1 year test was run in cooperation with [lexicon]IH[/lexicon].
Maybe Rossi had to set some boundaries with [lexicon]IH[/lexicon] and refuse some of their requests. [lexicon]IH[/lexicon] might have lost a bit of their confidence in the process.
