Which kind of intellectual property regime is more favorable to innovation: one
that enforces patents or one that does not? Economic theory is unable to answer this
question, as valid arguments can be made both for and against patents; hence we
must turn to empirical evidence. In this paper, we review empirical evidence gathered
by other researchers and add new evidence of our own. We conclude that the evidence
suggests that patents do not promote innovation, but instead retard it.
