Strategically I don't think GERS will be bought by a producer until the patent position is settled. IF GPRE, for example, ended up buying GERS and owning the patents this would encourage GPRE's competitors to ignore the patent and fight it any way they could. Noone in business wants to be beholden and cede an element of control to a main competitor.
