There might be a patent and what the original licensor thinks about what Viaspace is doing with their IP is an UNKNOWN of information we do not have access to. Perhaps all the original licensor wants is royalties, but they dont want to do the work to make it a world leading biofuel. You honestly think Carl threw 16 million at something that was that big of a gamble? I again, am banking on Carl knowing what he has with GKG. Carl is essentially branding this product just like this company is Miscanthus. Trademarks of brands don't protect much but they can be awfully important to stay ahead of the competition.
