Patentes, Fluxos internacionais de conhecimento, Sistema de inovaçãoResumo
Este artigo apresenta um banco de dados com patentes concedidas pelo USPTO para anos selecionados entre 1991 e 2009: 1.022.490 patentes, 786.780 patentes com citações internacionais e 4.064.995 citações transfronteiras - links em nossa análise. A rede formada por esses links internacionais tem como seus nós instituições -titulares das patentes. A revisão da literatura organiza argumentos para investigar citações de patentes como fluxos de conhecimento e reconhece problemas como diferenças entre citações de titulares e examinadores - um exercício para lidar com esse problema é apresentado. Essa rede tem firmas como a instituição predominante. Uma análise intertemporal mostra o crescimento da rede ao longo do tempo e a preservação de sua estrutura sem escala, evidência de sua resiliência. Com o tempo, essa rede evolui, mudando os setores líderes em uma matriz de interação entre patentes que citam e que são citadas - indícios de mudanças ocasionadas pelo surgimento de novos setores
