This is unfortunate, because there are plenty of empirical studies showing the benefits and costs of patents (search ssrn.com for "patents" and focus on the studies that use economic data). The upshot is, to date nobody has been able to say the one outweighs the other largely because they are not directly comparable.

But computer software and tech startups would be much better off since patents are purely harmful to software innovation.
Which points to one obvious reform.
On the other hand, there are multiple other studies showing how having a patent increases the chances of tech startups of a) receiving VC funding and b) making successful exits. I'd say it's still not clear that the software industry is being harmed more by patents than it is being benefited.
