摘要
文章以国内外硬质合金领域的专利数据为研究对象,构建影响专利价值的专利技术、经济和法律三维因素体系,运用多元线性回归模型探讨硬质合金领域专利价值的影响因素,挖掘影响国内外硬质合金领域专利价值的因素存在的差异性。布局国家数和权利要求数对硬质合金领域的专利价值具有显著正向影响,专利同族数对硬质合金领域的专利价值具有显著负向影响,且显著性不受专利申请地区影响;国内影响因素体系对硬质合金领域专利价值起显著正向作用的因素按影响程度依次为布局国家数、文献页数、权利要求数、IPC分类数、独立权利要求书的数量,起显著负向作用的因素按影响程度依次为专利同族数、引证专利数、专利申请人数;国外影响因素体系对硬质合金领域专利价值起显著正向作用的因素按影响程度依次为专利申请人数、布局国家数、引证专利数、权利要求数,起显著负向作用的因素为专利同族数;通过比较国内外硬质合金领域专利价值影响因素的实证结果,发现引证专利数和专利申请人数对国内硬质合金领域专利价值产生显著负向影响,但对国外硬质合金领域专利价值产生正向影响。提升硬质合金领域专利价值的建议:一是推动产学研协同创新,促进硬质合金领域技术知识流动;二是策略性布局海外硬质合金专利,提升专利产品竞争力;三是强化专利文件的撰写质量管理,提升硬质合金知识产权司法保护水平。
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.
