| 摘 要： | 目的/意义] 发明专利申请公开后，实质审查决定作出前，一直处于悬而未决的法律状态，此阶段对发明专利授权前景的评估，在理论和实践中都很有意义。方法/过程] 以1985-2014年国内申请人在生物技术领域向国家知识产权局（CNIPA）申请的88 304件发明专利为对象，构建基于专利文献的指标，通过Logistic回归模型，探讨影响专利授权的因素，通过分组回归和系数差异检验，分析不同类型创新主体专利授权影响因素的差异。结果/结论] Logistic回归结果表明，在生物技术领域，权利要求数、发明人数、是否提前公开、首项权利要求字数和专利文献页数等指标都与专利申请授权概率存在正相关关系；企业专利授权率低于大学和科研机构专利，但高于个人专利。分组回归系数差异检验结果表明，各变量对专利授权的影响在不同类型创新主体间存在显著差异。因此，专利授权分析中，对不同创新主体予以分类考虑很有必要。

| Abstract: | Purpose/significance]After the invention patent has been applied for and published,it has been in a pending legal status until the substantive examination decision is made.At this stage,the assessment of the prospects of patent grant is meaningful in theory and practice.Method/process]Taking the 88304 invention patents applied by Chinese applicants in the field of biotechnology in the National Intellectual Property Office(CNIPA)from 1985 to 2014 as the study object,constructing indicators based on patent documents,the factors which impacted patent grant are studied through Logistic regression.This paper compared and analyzed the differences in the factors affecting the patent grant of different types of innovation entities through group regression and comparison of coefficients.Result/conclusion]Logistic regression results show that the number of claims,the number of inventors,whether the applications are disclosed in advance,the number of words in the first claim,and the number of patent document pages are all positively related to the probability of patent grant in the field of biotechnology.The patent grant rate of enterprises is lower than that of universities and scientific research institutions,but higher than that of individual patents.The results of group regression coefficient difference test show that the influence of variables on patent grant is significantly different among different types of innovation entities.Therefore,in the analysis of patent grant in the field of biotechnology,it is necessary to classify and consider different innovation subject. |
