侵权诉讼背景下的专利无效宣告影响因素研究
Research on the Influencing Factors of Patent Invalidation under the Background of Infringement Litigation
摘要
Abstract
[Purpose/significance]Taking patent infringement as the starting point,this paper explores the influence mechanism of different factors on the tendency of patent infringement declaration,then compares and analyzes the differences in the influencing factors of invalid declaration under different infringement themes in the same field.[Method/process]Firstly,this paper uses the LDA topic model to subdivide the infringement topics in the selected emerging industry field,and understands the different infringement topics and infringement keywords of the infringement patents in this field;Secondly,the statistical correlation model is used to calculate various data indicators under different infringement classification topics and comparatively analyze the correlation between invalid declaration tendencies.Finally,by constructing a multi-feature fusion random forest model,the patents under different infringement classification topics are identified and trained for invalid declaration classification,and the LIME model in machine learning can be explained.Explain the degree of influence of the measurement index features in the model.[Result/conclusion]According to the correlation analysis after topic classification,it is found that under different topic classifications,the selected feature indicators not only have different overall influence on the determination of invalidity after infringement,but also have different influencing factors and influence degree rankings in different classification results.There existed significant differences in the classification rules and classification indicators relied on by different classification topics.关键词
