The figure selects the top 50 inventors in the number of patent applications for analysis. It can be seen from the figure that Toyota Motor Corporation has 2 main cooperative relationships in the field of power lithium-ion battery technology. Judging from the number of groups and the cooperative relationship between the inventors, Toyota’s technical personnel in the field of power lithium-ion battery electrode technology have relatively stable cooperative relationships and good technical communication and exchanges.
However, there are also key institutions that analyze their data and move the search results to the Innography database for key institution analysis. The analysis model provided by the Dialog Innography patent analysis platform comprehensively considers data such as the number of patents of the company, the number of patent categories, the number of regions involved in patents, the number of citations, operating income, and patent infringement. The established evaluation model, the ordinate reflects the company Owned resources, the abscissa represents the technical strength of the enterprise, and the size of the bubble represents the number of patents.
