Abstract:
Objectives:To explore the progress in the application of cardiovascular related innovative patent technologies between China and the United States from 2014 to 2023,and to further analyze the differences in driving forces and policy orientations in the transformation of scientific and technological achievements between the two countries,providing reference data for improving the efficiency of the transformation of cardiovascular scientific and technological achievements in China.Methods:Based on the Himmpat patent database,we searched invention patent application data in the cardiovascular fields by using the Fuwai Subject Headings and adopting the method of the international patent classification(IPC)-title-claims-abstract,from January 1,2014 to December 31,2023(excluding utility model and design patents).Fourteen indicators regarding patent value evaluation were selected as independent variables and the transfer and transformation rate of invention patent family as the dependent variable.Then we construct univariate and multivariate prediction models by utilizing logistic regression to compare and analyze the differences in various predictors for the transformation rate of patent family in the cardiovascular field between the two countries,and calculate the respective population attributable fraction(PAF)for each predictor.Results:Over the past 10 years,there have been 45 413 invention patent family in the cardiovascular field in China,which exceeded the 35 582 invention patent family in the United States.The transformation rate of cardiovascular invention patent family in the United States was 49.77%,while in China it was only 9.18%.In the United States,the transformation rate of invention patent family's applicants involving medical institutions is significantly higher than that of universities,research institutions,and enterprises,with transformation rates of 63.75%,56.74%,50.00%,and 49.76%,respectively.In contrast,in China,the transformation rate of invention patent family in the cardiovascular field is 6.87%in medical institutions and 7.90%in universities,slightly higher in research institutions(10.99%),while the highest rate is in enterprises(15.83%).Moreover,the transformation rates of biomedical invention patent family is higher than that of medical devices in China(9.45%vs.7.81%),while the opposite is true in the United States(42.39%vs.59.03%).The results of PAF based on full multivariate logistic regression,the top three predictors for the transfer and transformation of invention patent family in China are applicants including enterprises(PAF=71.17%),overseas distribution country number more than one(PAF=30.76%),and invention authorized(PAF=29.95%).In the United States,citation frequency exceeding 10 times(PAF=46.92%),overseas distribution country number more than one(PAF=32.56%),and applicants including enterprises(PAF=20.54%)are the top three predictors for the transfer and transformation of invention patent family.Conclusions:Since the implementation of the 13th Five-Year Plan,the number of patent family applications for cardiovascular related inventions in China has surpassed that of the United States.However,the transfer and transformation efficiency of cardiovascular invention patents in China is significantly lower than that of the United States.In depth analysis of the reasons,this study finds it mainly lies in China's insufficient research and development potential for high-value patents,weak awareness of overseas market layout,insufficient motivation for universities and medical institutions to transfer and transform invention patents,and the underutilization of the transformation potential of medical device invention patents as well.
