Thesis (Ph.D.)--University of Toronto (Canada), 2023.

In Chapter 1, I discuss Patent Assertion Entities (PAE) which are firms specialized in patent enforcement, and whose effect on innovation are theoretically ambiguous. I exploit a Supreme Court decision affecting PAEs incentives to file patent infringement lawsuits and cross-industry differences in exposure to empirically estimate the casual effect of PAE activity on innovative firms' performance. I find that the Supreme Court's ruling effectively discouraged PAEs' litigation and I show that sectors exposed to PAEs experienced a remarkable increase in their successful patent applications in response to the reduction of PAEs activity.Chapter 2 investigates the mechanism linking patent litigation and innovation. I develop a dynamic model of litigation where the defendant screens out heterogeneous plaintiffs through a series of out-of-court settlement offers. Employing granular information on patent infringement cases filed in the US from 2007-2021, I estimate my model. I find that patent litigation costs over $48.8 billion a year to listed defendants, $24.7 billion of which from settlement transfers. Furthermore, cases filed by PAEs have smaller stakes, lower quality, and are more likely to settle for smaller amounts. I consider two counterfactuals. First, I introduce a conditional fee-shifting rule, finding it effective in discouraging frivolous litigation, but likely to induce costly delays. Then, I turn to forum shopping, finding that restricting plaintiffs' discretionality in the choice of venue would dramatically reduce the incentives to file low-quality cases.Finally, Chapter 3 investigates systematic acquisitions of startups, which are prevalent in digital markets. I introduce a model of competition where demand depends substantially on the quality ranking of incumbents, which can be improved by R&D or acquisitions. I find that the prospect of acquisitions incentivizes startups investments when the incumbents are engaged in a neck-and-neck technological race, however these incentives fade as the leader escapes competition. Hence, when network externalities are strong enough, a forward-looking industry leader has significant incentives to lock the industry in a state of stagnation, where startups' investments are low, and killer acquisitions are prevalent.
