The determinants of parallel invention: Measuring the role of information sharing and personal interaction between inventors

Kang,Byeongwoo: Rudi Bekkers
WP#22-06 Hitotsubashi University IIR (2022/11/07)

Historical accounts describe numerous cases of parallel invention. Nowadays, with over half a million inventions yearly that apply for patent protection at the USPTO alone, it is likely that there are a lot of parallel inventions among these. Yet, the mechanisms behind creating similar knowledge remain unstudied. From both a theoretica…

          『Technological Forecasting and Social Change』 Vol. 179 (2022/06/01)

          The use of patent citation networks as research tools is becoming increasingly commonplace in the field of innovation studies. However, these networks rarely consider the contexts in which these citations are generated and are generally restricted to a single jurisdiction. Here, we propose and explore the use of a multilayer network fr…

                      Patent citations have been used for over four decades as indicators of numerous aspects of technological progress, including knowledge flows, technological evolution, and patent impact. However, research on these topics often ignores the variable contexts in which examiners, applicants, and third parties generate these citations, and t…

Departing from the instrumental rationality of neoclassical economics (Weber 1968), it has made a breakthrough with its foundational conception that economic action of individuals constructs social structures and these social structures heavily influence …
