International Knowledge Diffusion and Home‐bias Effect: Do USPTO and EPO Patent Citations Tell the Same Story?* (2010, unknown): “Typically cited documents refer to specific patent claims. examiners (Akers, 2000; Michel and Bettels, 2001; Breschi and Lissoni, 2004; EPO, 2005).”
The Role of External Linkages and Gatekeepers for the Renewal and Expansion of US Cities' Knowledge Base, 1990–2004 (2015, methodology): “…is likely to decay quite rapidly with the social distance among nodes, the external reach index was computed by considering only inventor pairs for which dij ≤ 4 (BRESCHI and LISSONI, 2004; SINGH, 2005).7 Fuller details on the computation of this index are available in the Appendix to this paper.”
Knowledge flows across European regions (2009, background): “Nonetheless, when aggregate citations are used as a proxy of knowledge interactions among regions, as in this paper, rather than an indicator of inventors’ face-to-face contacts this issue becomes less compelling (Breschi and Lissoni 2006).”
Technological Relatedness and Knowledge Space: Entry and Exit of US Cities from Patent Classes (2015, background): “…and inventive activity are legion (PAVITT, 1985; GRILICHES, 1990), and we are becoming increasingly aware of the difficulties of extracting increasingly sophisticated information from patent and citation records (BRESCHI and LISSONI, 2005; THOMPSON and FOX-KEANE, 2005; ALCACER and GITTELMAN, 2006).”
Applying social network analysis in economic geography: framing some key analytic issues (2009, background): “In providing empirical evidence, they were among the first to use patent data as relational data (see also Breschi and Lissoni 2004), provoking a trend in research on inventor networks (Balconi et al. 2004; Cantner and Graf 2006; Ejermo and Karlsson 2006).”
Mobility of Skilled Workers and Co-Invention Networks: An Anatomy of Localized Knowledge Flows (2009, background): “11 On the importance of patents for Pharmaceutical, Biotech and Chemical industry see Cohen et al. (2000) and Levin et al. (1987). 12 Biotech, Chemical and Pharmaceutical patents cover respectively 2.”
Research Networks and Inventors' Mobility as Drivers of Innovation: Evidence from Europe (2013, background): “Similar results are found by BRESCHI and LISSONI (2004) for Italy.”
The Geography of Complex Knowledge (2017, background): “We recognize that there are various channels through which knowledge flows over space between economic agents and that not all of these are captured by patent citations (see Breschi and Lissoni 2004).”
