Revisiting Antitrust Limits to Probabilistic Patent Disputes : Strategic Entry and Asymmetric Information

We consider separately strategic entry and asymmetric information in the design of the settlement policy governing patent disputes, with a focus on Shapiro(2003)'s consumer protection rule. We show that, when a potential entrant strategically incurs an entry cost before engaging in a patent dispute, a more stringent settlement policy of deterring costly entry benefits the patent-holder and may raise static efficiency. Concerning asymmetric information, when the disputants, but not the court, learn the patent validity, we derive an "expectation test," which requires that a laxer settlement policy be coupled with higher expected patent validity under settlement
