Ram,
Amazingly you may agree here with me. What would you think of a patent system for pharmacuticals that would auction off any newly patented drug that is effective (per whatever reg organization we agree). However, the catch is that every X% of the time, the government would buy the patent at the second highest bid price (this is a second price double blind auction which is the best kind of auction to maximize revenue for the auctioneer) and release it as a generic for all?
I don't know why you're running it by me. I am, after all, "awfully confused".
But seriously, it's not a bad idea, especially with
Ayatollah So's addendum. The presence of a government guarantee the majority of the time would provide security and incentive. Also, there is something familiar about the scheme you outline. Haven't you mentioned it before in another context?

Here's another idea to throw into the ring:
An Innovation Fund.
This is specifically designed for pharmaceuticals, and with a view to developing countries' development, but can be applied elsewhere. And it's not meant to be a complete replacement of the current system, but rather an addition to spur innovation in more useful directions.
Anyway, the fund backs a prize system, in which researchers are rewarded for the value of their innovations. Those making important discoveries in treating widespread and socially costly diseases, like AIDS, cancer, tuberculosis and malaria, would get bigger rewards. And they would have to be
big rewards to be effective.
Under this system, drugs can be supplied generically - at cost - to those suffering from the disease, whilst the innovators are still remunerated admirably from the fund. This would benefit both the developing countries' populations in the obvious ways, but also the developed countries, whose citizens would benefit from the improved, more socially useful, knowledge.
This would get us around the currently quite useless scenario in which pharma firms spend far more resources on developing (and patenting) cosmetic products like those treating hair loss and erectile disfunction than on products that actually save lives.
edit: Something else I forgot to mention about this is that it would be a more transparent and direct way to give aid than the huge wastage we currently have. Developed countries, rather than giving millions upon millions in aid, and worrying whether and where it will be spent, can rest assured that the money is going to what they intend. It would be guaranteed to be well spent. This also saves on all those ridiculously complicated and expensive transparency programmes that the World Bank currently backs, the efficacy of which is somewhat debatable.
