This review of William Patry’s How to Fix Copyright highlights three of Patry's themes. First is Patry’s insistence that copyright policy be based on real-world evidence, a suggestion that should be uncontroversial but instead runs headlong into the near-religious commitments of copyright stakeholders. Second is Patry’s emphasis on the difference between the interests of creators, on the one hand, and owners of copyright interests, on the other. Third, and finally, is Patry’s focus on the copyright system’s strong tendency to entrench business models and resist change, particularly in the face of new technology.
