[email protected]. Exclusionary and Diffusionary Levers in Patent Law1 Abstract The patent system is built on the premise that exclusion leads to innovation. But a mounting body of evidence calls into question the assumption that “innovation by exclusion” – innovation based on excluding rivals– is the only, or even primary, way innovation happens today: nearly 50% of manufacturers got the idea for their most important new product from an outside source that shared it with them, 45-60% of patentees acquire patents to access the technology of others, and over 1,300 companies, including five of the ten top holders of patents, have pledged to share their patents with others. But because of the patent system’s traditional focus on exclusion, policymakers have paid less attention to how patents can better support the diffusion of technology through mechanisms such as disclosure, transfer, waiver, and the pursuit of freedom to operate.
