This article provides new evidence on the patent trading flows of small and large firms. We document aggregate patterns of patent sales and acquisitions of small and large firms. We also examine the extent to which the initial innovator's and the potential buyers’ prior knowledge stocks in the same technology area and in geographical proximity with a patented invention are associated with the likelihood that the patent is sold, and whether the patent sold is bought by a small or large firm. To do so, we develop a dataset that matches patent sales and information on whether transacted patents are owned by small or large firms following a patent sale. 相似文献

选取京津冀经济圈为研究对象,估计全国1998—2015年高技术产业面板数据,在此基础上建立京津冀时间序列的VAR模型。研究结果表明:(1)全国高技术产业有效发明专利与产业发展间存在长期均衡关系,产业有效发明专利确实能带动产业发展;(2)RD活动内部经费支出对全国高技术产业发展作用最明显,而RD活动人员全时当量对产业发展具有不显著的负影响;(3)京津冀高技术产业有效发明专利和产业发展之间存在双向互动关系。 相似文献

The advancement of water sustainability and reliance highly depends on the implementation of innovative ideas. However, despite being a vital resource, the water sector still faces many challenges in innovations compared to other industries. This study investigated three different aspects of innovation activities in the water sector in Kazakhstan, which represents a typical developing country. First, the potential water-related issues calling for more innovation activities were investigated. Second, the trend of innovation activities over 30 years was investigated with the help of patents. Third, the disruptions rendered by COVID-19 to innovation activities in the water sector were investigated through a questionnaire survey. The analysis results showed that the total volume of contaminated wastewater generated in Kazakhstan has generally increased with time. The number of water enterprises, patented water-related innovations, and total general patents showed a strong association, with correlation values ranging from 0.66 to 0.99. In all firms, regardless of the scale investigated in this study, the availability of local expertise, the culture of local organizations toward innovation, and the country’s business environment are all considered to have a significant impact on water innovation processes. 相似文献

Today's Edisons or weekend hobbyists: technical merit and success of inventions by independent inventors 总被引:1,自引:0,他引:1
We set out to determine if independent inventors can be considered “heroes” or “hobbyists”, that is, if they produce the most or the least influential inventions in a product category. We study patented inventions by independent and firm-based inventors by comparing patents along four dimensions: Patent citation impact, detail, scope, and maintenance. Examining 225 tennis racket patents granted in the US between 1981 and 1991, we find that independent inventors are a heterogeneous group who generate inventions that are overrepresented both among the most impactful and the least impactful patents. The metrics we develop provide insight into ex ante identification of the importance of inventions. 相似文献
