Mapping technological trajectories as patent citation networks. An application to data communication standards
2009
Economics of Innovation and New Technology
We use patent citation networks to study the dynamics of technical change in Ethernet, a standard for data communication. We first consider the evolution of the broad technological system of Local Area Networks (LANs) and we identify the most significant inventions within the specific subfield of Ethernet. Then we analyse the structure of connectivity of patent citation networks to reconstruct the main technological trajectories in this subfield. Our results suggest that these technological
