The R&D status of joint patents on germanium dioxide, a promising next-generation power semiconductor, was analyzed using network analysis. By examining joint patent applications over time, the results show that, although the number of joint patent applications as a result of R&D competition has increased year by year, the content of the network has become more R&D intensive since the 2010s, as network indicators such as the number of nodes and the number of cluster counts show a decrease in the no. of nodes and the number of edges, as well as the clustering of a small number of nodes. We also identified power-law distributions in the proximity and eigenvector centrality graphs. The analysis integrates various network centrality indicators, time-series network diagrams suggesting a significant correlation between changes in the research network involved in power device manufacturing and dynamic shifts in new market creation.
