To analyze the welfare gain from allowing for differentiated patent protection across sectors, this study develops a … two-sector quality-ladder growth model in which patent breadth is a policy variable and derives the optimal patent breadth … under two policy regimes. We show that (i) the optimal uniform patent breadth is a weighted average of the optimal sector …

A special characteristic of the patent system is that it features multiple patent-policy levers that can be employed by … policymakers. In this study, we develop a quality-ladder model to analyze the optimal mix of patent instruments. Specifically, we … consider (a) patent breadth and (b) the division of profit in research joint ventures. We analytically derive optimal patent …
