摘要
针对已有发明专利质量评价指标的不足,引入专利引证质量指标。以新能源汽车行业中的储能技术为例,建立专利引证质量模型,通过对模型的检验,认为专利引证质量可作为发明专利质量评价的一项新指标,并证明了新引入指标的必要性。在此基础上,以比亚迪股份有限公司为例,运用主成分分析法对该技术领域的发明专利申请与审查文件中提取出的5项专利质量评价指标进行降维分析。分析表明新引入指标对于发明专利质量评价有较大影响,证明了新引入指标的重要性。综合新构建的发明专利质量评价指标与已有发明专利比率评价指标进行分析,验证了新构建指标体系的有效性。
In view of the shortcoming of the existing evaluation index of invention patent quality, the index of patent citation quality is introduced. Taking the energy storage technology of new energy automobile as an example, a patent citation quality model is established and tested. The study shows that patent citation quality can and should be used as a new index to evalu- ate the invention patent quality. On this basis, taking BYD limited company as an example, the dimensions of 5 patent quali- ty indicators extracted from the invention patent application and review documents are reduced by adopting PCA method. The results show that the new introduced index has great influence on the invention patent quality evaluation, indicating the importance of the new index. Meanwhile, through synthetic analysis of the new introduced index and existing evaluation indexes, the validity of the new established index is verified.
