Abstract Objective To analyze the general situation of patent application and authorization of 1 497 tertiary public hospitals in China from 2010 to 2019, to provide reference and basis for improving the awareness of intellectual property protection in public hospitals and promoting the application and transformation of patents in the field of medical and health care at the same time. Methods Patent data were searched through Baiteng net patent database, and SPSS 19.0 was used for statistical analysis. Results From 2010 to 2019, there were a total of 94 321 from 1 497 tertiary public hospitalsin china, among which 62 377 were for utility model patents and 31 944 for invention patents. The total number of valid patents was 46 532, accounting for 49.33% of the total number of patent applications. The number of invalid patents was 26 520, accounting for 28.12% of the total number of patent-applications. The number of patent applications and valid patents was positively correlated with the GDP and the number of health technicians per thousand population (r=0.949, 0.882, 0.938, 0.861 respectively, P<0.05). The provinces with more than 1000 patent applications were mainly distributed in east China, central China, south China and southwest China. There were 26 provinces and municipalities that jointly applied for patents. The number of patents jointly applied for accounted for 0.47% of the total number of patent applications. Conclusion The number of patent applications of tertiary public hospitals increased year by year. The utility model patents are the main ones, the number of invention patents is small, and the patent failure rate is high. Patent-area distribution is uneven. It is suggested that all localities establish and improve the training system and incentive measures for patent applications, encourage the application of invention patents, and increase the total number and quality of patents.
