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

Higham,Kyle, MartinaContisciani, CaterinaDe Bacco
『Technological Forecasting and Social Change』 Volume 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…
