Say you owned the patent, the research was solid, high likelihood it would work, but needed a 1000 patient phase 3 trial and whatever, that you can't and don't know how to do. Would you "outsource"¹ the work for price of an exclusive right to make the drug? Would you ask for something in return? Remember, it is we - the people - that have the right and resources, and in our name our representatives distribute them to researchers and make the deals with salesmen. ¹ more like sell the businness * Personally not from US, wanted to show the framing. In any case, most research is an international effort, so maybe I shouldn't completely exclude myself.
