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

Measuring patent assessment quality—Analyzing the degree and kind of (in)consistency in patent offices’ decision making 总被引:1,自引:0,他引:1
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

政策测量、政策协同与技术绩效:基于中国创新政策的实证研究(1978-2006) 总被引:4,自引:0,他引:4
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
