Madam, Sir, dear members May I remind you of the last event of this year On Monday, December 18, 2017 Bernhard Ganglmair The University of Texas at Dallas speaks about "The Effect of Patent Litigation Insurance: Evidence from NPEs" (joint work with Christian Helmers, Brian Love, and Shawn Miller) * Abstract infra 16.00 - 18.00 hours Venue: Seminar 31, Law School (Juridicum), Schottenbastei 10-14, 1010 Vienna (entrance from Hessgasse) Followed by traditional Advent punch For the sake of planning your registration is apprechiated at sonnenfels.economics@univie.ac.at <mailto:sonnenfels.economics@univie.ac.at> Wolfgang Weigel ABSTRACT: "We analyze the extent to which private defensive litigation insurance deters patent assertion by non-practicing entities (NPEs). We do so by studying the effect that a patent-specific insurance product, offered by a leading litigation insurer, had on the litigation behavior of insured patents' owners, all of which are NPEs. We first model the impact of defensive litigation insurance on the behavior of patent enforcers and accused infringers. Next, we empirically evaluate the insurance policy's effect on the owners of insured patents by comparing their subsequent assertion of insured patents with their subsequent assertion of other patents they own that were not included in the policy. We additionally compare the assertion of insured patents with patents held by other NPEs with portfolios that were entirely excluded from the insurance product. Our findings suggest that the introduction of this insurance policy had a large, negative effect on the likelihood that a patent included in the policy was subsequently asserted, and our results are robust across all control groups that we constructed. Our results have importance for ongoing debates on the need to reform the U.S. and European patent systems, and suggest that market-based mechanisms can deter so-called "patent trolling."
