Topology and evolution of technology innovation networks

Sergi Valverde, Ricard V. Solé, Mark A. Bedau, Norman H. Packard · 2007 · Physical Review E

Summary. Patent citation networks from the U.S. Patent and Trademark Office reveal how technological innovations connect and evolve over time. The network exhibits scaling patterns consistent with preferential attachment and aging effects, similar to scientific citation networks. This suggests a universal mechanism governs how innovations build on prior ideas and designs.
