Multiple Linear Regression Analysis of Patent Value in Cemented Carbide Field in China and Other Countries
This paper takes the patent data in the field of cemented carbide in China and abroad as the research object,constructs the three-dimensional factor system of patent technology,economy,and law that affect the patent value,uses the multiple linear regression model to explore the influencing factors of the patent value in the field of cemented carbide,and excavates the differences of the factors that affect the patent value in the field of cemented carbide in China and abroad.The number of countries and the number of claims have a significant positive effect on the patent value in the cemented carbide field,while the number of patent families has a significant negative effect on the patent value in the cemented carbide field,and the significance is not affected by the region of the patent application.The factors that have a significant positive effect on the patent value in the field of cemented carbide in the influence factor system of China are the number of countries,the number of pages of literature,the number of claims,the number of IPC categories,and the number of independent claims according to the degree of influence,and the factors that have a significant negative effect are the number of patent family,the number of cited patents,and the number of patent applications.The factors that have a significant positive effect on the patent value in the field of cemented carbide in the influence factor system of other countries are the number of patent applications,the number of countries,the number of cited patents,the number of claims according to the degree of influence,and the factor that has a significant negative effect is the number of the patent family.By comparing the empirical results of the factors affecting the patent value in the field of cemented carbide in China and abroad,it is found that the number of cited patents and the number of patent applications have a significant negative impact on the patent value in the field of cemented carbide in China but have a positive impact on the patent value in the field of cemented carbide in other countries.Suggestions to enhance the patent value in the field of cemented carbide are as follows.The first is to promote collaborative innovation among industry,university,and research and the flow of technical knowledge in the cemented carbide field.The second is to apply the strategic layout of overseas cemented carbide patents to enhance the competitiveness of patented products.The third is to strengthen the quality management of patent documents and improve the judicial protection level of intellectual property rights for cemented carbides.
