Counterarguments to Patent Protection
1.    Prevents innovation
a.    Tragedy of the anti-commons: Everyone patents a piece, nobody can put them together.
2.    Computer science argument: We file patents defensively bc we’re afraid someone else will take the invention from us. Don’t want legal regime to be involved.
3.    Many times it is clear that the party holding patent didn’t contribute anything to world. Came up with invention and leaned back to wait for somebody else to come up with it, and took their money.
