Kang, Byeongwoo:Rudi Bekkers:Atsushi Ohyama
『Research Policy』 Vol. 53 Issue 10 pp. 1-16 （2024/12/01）

There is abundant evidence that individuals create similar ideas independently at about the same time. While this phenomenon has often been documented, its underlying mechanisms have been understudied empirically.

Multilayer patent citation networks: A comprehensive analytical framework for studying explicit technological relationships

Higham, Kyle: Martina Contisciani: Caterina De Bacco
『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…

Higham, Kyle:Gaétan de Rassenfosse:Adam B. Jaffe
『Research Policy』 Vol. 50 Issue 4 （2021/05/01）

The quality of novel technological innovations is extremely variable, and the ability to measure innovation quality is essential to sensible, evidence-based policy. Patents, an often vital precursor to a commercialised innovation, share this heterogeneous quality distribution. A pertinent question then arises: How should we define and …
