Citation network and main path analysis of monkeypox virus. (a) Global citation network. Including all patent documents and their citation links. Larger nodes represent patents that have been cited more often. The node size is set according to its output value. The larger the output value is, the larger the node size and the more times a given patent has been cited. To separate the different technologies, we divided the technology categories into five communities, as described in supplementary information Table S1 and Fig.S2. Then, the layout was presented through the technical classification of nodes (patents), and the “grid layout” strategy of Gephi software was used to reference the network in the same technical module. (b) Main path. Pajek was used for main path analysis of patent citation and landmark patents were labeled
