Analysis and Evaluation of the Status of Cardiovascular Patents in Ten Major Countries Worldwide From 2016 to 2023
Objectives:To compare the patent protection and application status of cardiovascular technology innovation in ten major countries worldwide from 2016 to 2023,and to analyze and evaluate the relative competitiveness and innovation ability of technology achievements in the cardiovascular fields in China,providing reference for improving the transfer and transformation rate of scientific and technological achievements in this field.Methods:Based on the HimmPat,IncoPat,and Wisdom Seed patent databases,using the Fuwai Subject Headings,we searched patent application data in the cardiovascular fields from ten major countries worldwide from January 1,2016 to December 31,2023 by adopting the method of the International Patent Classification(IPC)-Title-Claims-Abstract.We compared and analyzed specific indicators from the three dimensions of the patent,including technology value,legal value,and economic value.Results:Over the past eight years,the total number of patent applications in the cardiovascular fields was counted from the perspective of patent applicant addresses to analyze the technological innovation capabilities in cardiovascular field of each country.The results showed that China ranked the second in the world in terms of the total number of patent applications in the cardiovascular fields,with approximately 46 536,followed the United States with 75 382.Although the number of patent family applications in China is higher than that in the United States(32 879 vs.19 587),overseas applications for family patent in China only account for 25.4%of its total patent application volume,which is only higher than that in Russia(15.5%),while much lower than that in the other eight countries.In terms of the average number of patent applicants,there are only 2.61 applicants per patent in China,compared with 10.02 in the United States and 12.69 in Germany.In terms of citation frequency of simple patent family,the United States has 9.76 citations per patent,while China has only 2.64 citations per patent.Besides,the patent transfer rate in China is also relatively low with a proportion of only 7.3%.Conclusions:The economic development,government policy support and technological advancement jointly contribute to the continuously increased number of cardiovascular patent applications in China.However,the patents are associated with poor quality,insufficient overseas layout,and insufficient horizontal cooperation in technological innovation,which may also be the main reasons for the insufficient momentum and efficiency of patent achievement transformation.
