Norbäck, Pehr-Johan; Olofsson, Charlotta; Persson, Lars - 2020

Patent breadth in an international setting
Bond, Eric W.; Zissimos, Benjamin - 2017
We examine the Nash equilibria of a game where two national governments set patent breadth strategically. Broader patents make R&D more attractive, but the effect on static efficiency is nonmonotonic. In a North.South model, where only the North can innovate, harmonization of patent breadth...

A model of patent trolls
Choi, Jay Pil; Gerlach, Heiko A. - 2015
This paper develops a model of patent trolls to understand various litigation strategies employed by nonpracticing entities (NPE). We show that when a NPE faces multiple potential infringers who use related technologies, it can gain a credible threat to litigate even when it has no such...
