Well, in case Greg doesn't, I think I might try. I don't remember if
this paper has been discussed here, but as many of you would know the
Bessen & Hunt study shows statistical evidence of swpats replacing R&D
spending, so maybe one could consider that a proof. The difference
with prior literature, if I understand it well, is that before May
2003 there was anecdotal evidence and reasonable economic theories
that swpats did harm innovation, and no evidence or sound theory that
they helped it. Now we have anecdotal evidence and reasonable economic
theories, and statistical trends evidence that swpats did harm
innovation, and still no evidence or sound theory that they helped it

I'm still reading it, though (a bit hard with my background). I think 
it's at
