An analysis of the bifurcated patent litigation system ispublished: pub subjects: subjects_ECO abstract: In bifurcated patent litigation systems, claims of infringement and validity of a patent are decided independently of each other in separate court proceedings at different courts. In non-bifurcated systems, infringement and validity are decided jointly in the same proceedings at a single court. We build a model that shows the key trade-off between bifurcated and non-bifurcated systems and how it affects the incentives of plaintiffs and defendants in patent infringement cases. Using detailed data on patent litigation cases in Germany (bifurcated) and the U.K. (non-bifurcated), we show that bifurcation creates situations in which a patent is held infringed that is subsequently invalidated. We also show that having to challenge a patent’s validity in separate court proceedings under bifurcation implies that alleged infringers are less likely to do so. We find this to apply in particular to more resource-constrained alleged infringers. Finally, we find parties to be more likely to settle in a bifurcated system. date: 2016-11 date_type: published publisher: Elsevier official_url: http://tse-fr.eu/pub/30846 faculty: tse divisions: tse keywords: Litigation keywords: patents keywords: bifurcation language: en has_fulltext: TRUE view_date_year: 2016 full_text_status: public publication: Journal of Economic Behavior and Organization volume: vol. 131 pagerange: 218-242 refereed: TRUE issn: 0167-2681 oai_identifier: oai:tse-fr.eu:30846 harvester_local_overwrite: oai_set harvester_local_overwrite: issn harvester_local_overwrite: faculty harvester_local_overwrite: keywords harvester_local_overwrite: publisher harvester_local_overwrite: creators_affiliation harvester_local_overwrite: id_number harvester_local_overwrite: creators_idrefppn harvester_local_overwrite: volume harvester_local_overwrite: creators_halaffid harvester_local_overwrite: pending oai_lastmod: 2021-06-24T13:00:01Z oai_set: tse oai_set: ut1c site: ut1 citation: Cremers, Katrin, Gaessler, Fabian, Harhoff, Dietmar , Helmers, Christian and Lefouili, Yassine (2016) Invalid but infringed?
