摘要
研究高收益专利审查周期影响因素对提升专利审查效率非常重要。以1993—1999年期间中国授权的维持届满专利为样本,采用Violin Plot和Cox回归模型,分阶段研究高收益专利审查周期的影响因素发现:初步审查周期与申请人国别显著相关;实质审查周期与申请年份、技术领域、申请人国别、IPC分类数、优先权国家文本数、权利要求数、发明人数和专利被引数显著相关,其中IPC分类数、优先权国家文本数和权利要求数是实质审查周期的保护因素,发明人数和专利被引数是危险因素。建议在初审阶段压缩初审期限,延期理由严格化,探索申请人需求导向型审查模式;在实审阶段将技术领域实审部门精细化,合理限定权利要求边界和数量,加强建设智能检索系统,优化审查流程等;探索检索外包等创新审查模式,确保审查质效平衡。
It is very important to study the factors that influence the examination period of high-profit patents to improve the efficiency of patent examination.This paper takes patent applications to the China National Intellectual Property Administration(CNIPA)from 1993 to 1999,which have lasted for 20 years as a sample.By observing the mechanism of patent examination by the Chinese Patent Office,the examination period could be divided into two stages:the preliminary examination period and the substantive examination period.The Violin Plot analysis and Cox regression model are used to conduct a phased study on influence factors on the examination period of high-profit patents.Specifically,the Violin Plot is used to analyze the distribution of application years,technical fields and applicant countries on the examination period in different stages.The Cox regression model is used to explore the correlation between the variables and the substantive examination period.The variables include the number of IPC classifications,the number of simple patent families,the number of priorities,the number of claims,the number of inventors,the number of references to patent literature/non-patent literature and the number of forward citations.According to the response of the Violin Plot to the data,the main findings are as follows:Firstly,the preliminary examination period and the substantive examination period are very unevenly distributed,with obvious discrete values.Secondly,the substantive examination period as a whole is longer than the preliminary examination period.Thirdly,the preliminary examination period is not greatly affected by the different application years and technical fields,but is significantly affected by the different applicant countries.Fourthly,the substantive examination period is significantly affected by the different application years,technical fields,and applicant countries.Judging from the final operating results of the Cox regression model,the substantive examination period of high-profit patents has a signi
