My hunch - based on the "delays" in news - is that the big players figure they have the resources (i.e., time & money) to either do the research on their own or evaluate all the third-party alternatives before going in on a licensing deal.
I hate to say it... but I think Lexaria's technology is basically "ahead of its time" for now; and so we have to wait (and hope nothing better comes along).
(No analogy is perfect, but...) Imagine, if you would, if SmallCompanyX approaches Ford and says: "We've got a revolutionary, patented hydrogen engine that's going to blow-open the whole hydrogen-powered car market - when it becomes legal next year." Ford could:
(a) Take one look at it and "sign on the dotted line".
(b) Figure: "Hey - we've got a whole frickin' year and a boatload of cash (and research divisions) to look into hydrogen engines ourselves. And you know what - if we end-up with a similar solution (i.e., patent infringement problem), we'll deal with it when we get there. Heck, by the time that happens, [SmallCompanyX] will probably be so strapped for cash, they'll be begging us to buy them out - i.e., patent problem solved."
I think the latter might be what has happened/is happening. :/
