Research Policy Vol. 45, No. 1 (2016): 218-231.<\/h4>\n<p><a href=\"https:\/\/ssrn.com\/abstract=2457611\" target=\"_blank\">https:\/\/ssrn.com\/abstract=2457611<\/a><\/p>\n<p>This paper empirically investigates the statistical relation between levels of patent litigation and venture capital (&#8220;VC&#8221;) investment in the U.S. We find that VC investment, a major funding source for entrepreneurial activity, initially increases with the number of litigated patents, but that there is a &#8220;tipping point&#8221; where further increases in the number of patents litigated are associated with decreased VC investment, which suggests an inverted U-shaped relation between patent litigation and VC investment. This appears strongest for technology patents, and negligible for products such as pharmaceuticals. There is some evidence of a similar inverted U-shaped relation between patent litigation and the creation of new small firms. Strikingly, we find evidence that litigation by frequent patent litigators, a proxy for PAE litigation, is directly associated with decreased VC investment with no positive effects initially.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Catherine Tucker<\/p>\n","protected":false},"author":6977,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[16],"tags":[25,26,7,9],"_links":{"self":[{"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/posts\/204"}],"collection":[{"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/users\/6977"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/comments?post=204"}],"version-history":[{"count":3,"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/posts\/204\/revisions"}],"predecessor-version":[{"id":240,"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/posts\/204\/revisions\/240"}],"wp:attachment":[{"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/media?parent=204"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/categories?post=204"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sites.bu.edu\/tpri\/wp-json\/wp\/v2\/tags?post=204"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
