I don't know, I might have before you Else lol!
But the IP market gives me the creeps, it is heavily suited to less mindful very large companies and their drones, than to the masses with a lot of creative potential, making a real drain and bottleneck even for companies. You should not have to go into hock for heaps just to the establish and protect a patent world wide, before you go and do anything with it, or be required to go through very expensive NDA processes and further development in secret hunting for investors etc. A true market place is, you have it listed people look at it, and say, there's one, and contact you, rather then you hunting across the country or planet for somebody to NDA and license. It would make the rate of progress and change rapidly speedup and get rid of lesser solutions quicker. In an more open market place multiple companies could license at once without negotiation at set rates (the rate calculation is a little complex but something I come up with maybe in the 1990's). You never need to meet a licensee, but if they have any sense they would use you as a consultant.
