高价值专利影响因素分析及主题挖掘——以纳米药物领域为例

A Study on the Factors Influencing High-value Patents and Topic Mining in the Field of Nanodrugs

挖掘高价值专利影响因素及主题有利于政府和企业进行前瞻性专利战略部署,对抢占技术先机、赢取竞争优势具有积极意义。文章首先依托专利数据,采用因子分析法计算专利综合价值评分,依据二八原则筛选高价值专利;然后对专利指标及其分类标签进行特征分析、差异性分析和回归分析,探究影响专利价值的因素;最后使用BERTopic主题模型挖掘高价值专利主题。选取“纳米药物”专利数据进行实证分析,结果表明该方法能有效探究出专利价值的强影响因素,筛选出的高价值专利与其他方法获得结果高度一致。

Exploring the influencing factors and themes of high-value patents is conducive to forward-looking patent strategies made by governments and companies,and has positive implications for seizing technological opportunities and gaining competitive advantage.The article first draws on patent data,uses factor analysis to calculate the comprehensive value score of patents,and selects high-value patents based on the Pareto principle(80/20 rule);then it conducts feature analysis,difference analysis,and regression analysis on patent indicators and their classification labels to explore the factors affecting patent value;finally,it uses the BERTopic model to screen high-value patent themes.The empirical analysis of the patent data of"nanodrugs"shows that this method can effectively explore the strong influencing factors of patent value,and the screened high-value patents are highly consistent with the results obtained by other methods.
