The heterogeneous effects of patent scope on licensing propensity     

《Research Policy》2023,52(3):104696

How does patent scope influence licensing propensity of inventions? Prior studies have often been confined to specific industries or settings, and their results have been mixed with studies showing a positive, a negative, or even no significant relationship. Also, while some have explored moderating factors that might influence the patent scope-licensing relationship, a systematic investigation of the heterogeneous effects of patent scope on licensing at the invention level has not been undertaken. This study combines a broad sample of publicly reported patent licensing agreements and a novel methodology that captures an exogenous variation in patent scope to re-investigate the relationship between patent scope and licensing and to explore key invention and inventor characteristics that could influence this relationship. The results show that narrowed patent scope leads to a substantial decline in licensing propensity of inventions and that the effect is stronger for high-quality, science-based, and novel inventions as well as for inventions generated by small inventors.  相似文献   

Linguistic metrics for patent disclosure: Evidence from university versus corporate patents     

《Research Policy》2023,52(2):104670

Encouraging disclosure is important for the patent system, yet the technical information in patent applications is often inadequate. We use algorithms from computational linguistics to quantify the effectiveness of disclosure in patent applications. Relying on the expectation that universities have more ability and incentive to disclose their inventions than corporations, we analyze 64 linguistic measures of patent applications, and show that university patents are more readable by 0.4 SD of a synthetic measure of readability. Results are robust to controlling for non-disclosure-related invention heterogeneity. The linguistic metrics are evaluated by a panel of “expert” student engineers and further examined by USPTO 112(a) – lack of disclosure – rejection. The ability to quantify disclosure opens new research paths and potentially facilitates improvement of disclosure.  相似文献   

纤维素分解菌的分离、筛选及其环境适应性初步研究   总被引：14，自引：0，他引：14  

孙晓华  罗安程 《科技通报》2005,21(2):236-241

以滤纸平板和羧甲基纤维素钠培养基为基础培养基,从采集的样品中筛选出具有分解纤维素能力的38株菌株。采用纤维素刚果红培养基进行粗选,得到10株透明圈较大的菌株。将这10株菌株进行液体发酵培养,测定其酶活力,得到4株分解纤维素能力较强的菌株。对这4株菌株进行碳源、温度、pH值的适应性研究。结果发现,真菌3和真菌6的适应性都比较好。  相似文献   

风险投资、区域创新与创新质量甄别          下载免费PDF全文

许昊  万迪昉  徐晋 《科研管理》2017,38(8):27-35

利用基于风险投资案例和专利申请与授权的中国省际面板数据,研究了风险投资对区域技术创新产出的促进作用和风险投资在"研发投入—创新产出"转化过程中的创新质量甄别效应。研究发现:(1)风险投资促进了中国区域技术创新产出,并呈现出滞后效应和"倒U型"趋势,其在滞后二期和三期显著性水平和创新效果达到最优;(2)风险投资对经济和科技欠发达的西北与东北地区创新产出促进效果最佳,而对经济和科技较发达的东部和中部地区创新产出促进作用不明显;(3)风险投资甄别了创新产出的质量,其有效抑制研发投入转化为以外观设计和实用新型为代表的低质量创新产出,而积极促进研发投入转化为以发明专利为代表的高质量创新产出。  相似文献   

对“专利流氓”“鲶鱼效应”的思考与建议     

曾莉  戚功琼 《科技管理研究》2017,(15)

"专利流氓"是市场经济的产物,其存在和发展符合市场竞争规律,美国高智发明(Intellectual Ventures,IV)和Vringo等"专利流氓"公司以及大量专利诉讼案件的出现证明其具有强大的生命力,是专利运营模式的一种创新。运用"鲶鱼效应"理论,从"专利流氓"激励专利运营、盘活专利资源和提高企业创新能力的视角阐述其带来的正面影响。建议我国中小企业在面对"专利流氓"时持辩证和理性的态度,并建议我国立法、司法和行政机关协同合作来制约"专利流氓"滥用专利权利的现象。  相似文献   

基于专利视角的京津冀医药制造业协同创新评价研究     

王坤  李春成  马虎兆 《科技管理研究》2017,(19)

京津冀协同发展上升到国家战略,产业协同创新情况到底如何值得深入研究。选取京津冀地区的医药制造业作为研究对象,采用京津冀地区医药制造业1995年～2015年专利方面的数据建立复合系统协同度模型,对区域内部医药制造业各自和整体协同度进行测算评价,研究结果表明：（1）区域内专利指标的序参量呈现逐年上升的趋势,说明专利方面的创新趋于有序;（2）协同创新子系统中专利价值子系统的重要地位逐渐显现;（3）京津冀医药制造业协同创新水平不断提升,但目前整体协同创新程度仍居于中等水平。  相似文献   

嗜热纤维素分解菌分离和筛选     

邱成书  王春瑶  杨泽雄  王立宏 《蒙自师范高等专科学校学报》2009,7(2)

从温泉、堆肥等环境采集样品,以滤纸条为唯一碳源,用微晶纤维素粉和羧甲基纤维素钠(CMC-Na)-刚果红培养基进行分离和筛选出几株高温纤维素分解菌.进行测定这些菌株的Cx、滤纸酶活性试验,两种酶的作用温度相对较宽,Cx酶的最适酶活性温度约70℃,而滤纸酶活性的最适温度因菌株差异有所差异.  相似文献

Policy and evidence: a critical analysis of the Year 1 Phonics Screening Check in England          下载免费PDF全文

Hans U. Grundin 《Literacy》2018,52(1):39-46

“This paper aims to present a critical analysis of the Year 1 Phonics Screening Check (PSC), with special focus on the relationship between the UK Department for Education's policy‐making and the evidence considered in the process of developing and evaluating the PSC. The reports from the in‐house Standards and Testing Agency and from commissioned external organisations with limited remits have been analysed, with emphasis on how the screening check findings have been used in DfE decision‐making. My conclusion is that the department has overestimated both the validity and the reliability of the check: partly because important sources of measurement error have not been explored, and partly because the available evidence has not been analysed in sufficient depth — or perhaps simply been ignored by the department. The whole phonics screening check seems to be the product of policy‐based evidence, rather than evidence‐based policy‐making. This has, in my view, seriously undermined the value of the PSC as a screening instrument, and one must wonder whether it is ‘fit for purpose’.  相似文献
