ABSTRACT={Technological co-occurrence graphs in innovation economics are built using patent data, extracting the technological classes associated with inventions by experts from intellectual property offices. Co-occurrence occurs when the same invention is allocated to several technologies. The last decade has seen the development of many original methods for processing patent data via these co-occurrence graphs. The objective of this article is to identify and illustrate the issues of the innovation economy addressed by technological co-occurrence graphs.}}
