Intellectual property law is designed to protect knowledge from the free-rider problem, but critics suggest it gives firms monopoly power. Both views are oversimplified.

When policymakers hear about IP at all, it is generally from misleading viewpoints that can be placed between two extremes. At one end is the notion that intellectual property anywhere and everywhere creates monopoly. At the other is a “nothing to see here” approach that treats market concentration and market power as rare exceptions in the IP world. In reality, the interplay between grants of exclusive rights and competition is complicated and evades simple classification.
