Abstract

This paper uses the method of cluster analysis to analyze the patent development in Tianjin. Based on the relevant data from 2006 to 2019, this paper analyzes the patent application and patent structure in Tianjin, and analyzes the development trend of the proportion of invention patents, job patents and development subjects in Tianjin. The growth rate of patent licensing in Tianjin is generally higher than the overall growth level of patent licensing in China. The proportion of invention patent applications in Tianjin has been lower than the overall proportion of the country, and is in a continuous decline. The proportion of service invention patent applications in Tianjin also showed steady growth. The results of cluster analysis showed that the patent development of Tianjin ranks fifth in the country, indicating that the overall patent application and technological innovation ability of Tianjin is in a medium position in the country.
