How is knowledge distributed over space and how are different types of knowledge related? These questions have so far received little attention. In this paper we measure knowledge relatedness based on the relationship between individual patent categories by using coclassification information obtained from EPO patents. We also follow specialization of countries and its evolution over the past three decades. We focus on the EU, the United States and China. The objective of this paper is to identify the knowledge relatedness between technological fields and to map knowledge produced in selected countries. For visualization of knowledge relatedness network analysis has been used.

Klíčová slova: patents, knowledge relatedness, knowledge space, network analysis, EPO patents, technological advantage
