Citations, family size, opposition and the value of patent rights   总被引:5,自引:0,他引:5  
We combine estimates of the value of patent rights from a survey of patent-holders with a set of indicator variables in order to model the value of patents. Our results suggest that the number of references to the patent literature as well as the citations a patent receives are positively related to its value. References to the non-patent literature are informative about the value of pharmaceutical and chemical patents, but not in other technical fields. Patents which are upheld in opposition and annulment procedures and patents representing large international patent families are particularly valuable.  相似文献

Based on Laplace transform theory, chaos synchronization of the fractional order unified system by using the one-way coupling method presented in Xiangjun et al. [Chaos in the fractional order unified system and its synchronization, Journal of the Franklin Institute 345 (2008) 392-401]. In this note, we present some points to the mentioned paper.  相似文献

We argue that consistent decision making in judging a patent's validity and basing this on its underlying technological quality are important elements of patent office service (“assessment”) quality. To understand which level of assessment quality patent offices (can) provide, particularly in new technological areas, we study the concordance of the European Patent Office's (EPO) granting and opposition decisions for individual patents. Using the biotechnology industry in the 1980s (an emerging patenting area then) as an example, we find no empirical evidence that the EPO provided maximal or optimal assessment quality as far as can be told from bibliographic indicators. We discuss research limitations and consequences of this first empirical analysis, and suggest ideas for refinements in future work.  相似文献

以创新政策为例,在政策量化方面进行了研究.通过量化政策,测量了政策之间的协同问题,并最终利用扩展的柯布一道格拉斯生产函数研究了政策协同与技术绩效之间的关系.给出了具体的政策量化标准操作手册,并利用计量模型得出了一些新的结论:第一,政策力度能够促进技术绩效的增长,而政策部门之间的协同对技术绩效的影响具有显著差异;第二,引进外资与创新协同能够在很大程度上促进专利授予数量的提高.对重大发明创造没有显著影响,却在一定程度上削弱了新产品产出比率;第三,人事措施与行政措施的协同对重大发明创造与新产品产出比率具有显著的正面影响,而对专利授予具有显著的负面影响.  相似文献

基于1995—2012年新疆的时间序列数据,采用耦合协调度方法及灰色关联模型,探讨新疆生产性服务业与制造业协调发展的关系及影响因素。研究表明,新疆生产性服务业与制造业耦合协调度较低,处于周期性失调的状态。新疆生产性服务业与制造业协调影响程度排序为:经济发展结构资本累积科学创新金融支持力度经济外向性程度人力资本。建议两者从产业融合、科学创新、固定资产投资和外商投资方面做出调整,实现新疆生产性服务业与制造业协调发展。  相似文献
