The private value of software patents     

Bronwyn H. Hall 《Research Policy》2010,39(7):994-1009

We investigate the value creation or destruction associated with the introduction of software patents in the United States in two ways. The first looks at the cumulative abnormal returns to Information and Communication Technology (ICT) firms around the time of important court decisions that impacted software patents, and the second analyzes the relationship between firms’ stock market value, the sector in which they operate, and their holdings of software patents. We conclude that the market evaluated software patents as a negative development ex ante. Ex post, a greater number of firms in all ICT sectors invested in these patents, and these firms had slightly higher market values than those with no software patents. However, while we obtain clear evidence that the technological importance or quality of patented innovation mattered for the market value of hardware firms both before and after the legal changes, it is less clear that the marginal patent right per se was associated with increases in market value, and there are no significant valuation effects associated with patents for pure software firms after the change.  相似文献   

基于系统动力学的种业国际化知识产权风险研究     

陈燕娟  邓岩 《科技管理研究》2023,(1):137-145

在界定种业国际化知识产权风险影响因素的基础上，运用系统动力学方法构建风险研究模型，仿真模拟种业国际化知识产权风险的动态变化，探究各类影响因素之间及其对于种业国际化知识产权风险的作用关系。研究表明，种业国际化知识产权风险是一个复杂的动态系统，整体风险存在显著的累积效应；知识产权运营风险对整体风险的影响最大也最突出，各类子系统风险交织共振导致整体风险叠加扩大；各类子系统风险均与整体风险变化正相关，整体风险对知识产权特性风险和环境风险变化更加敏感。为了有效管理种业国际化知识产权风险，中国种业应采取强化风险预警和前馈控制、夯实知识产权运营能力、提高企业自主创新水平、实施区域差异化风险管理等措施。  相似文献   

论农业知识产权绿色发展的政策过程及导向     

倪源  王仁文  高亮 《科技管理研究》2022,(3)

在绿色发展理念指引下,农业知识产权政策既要致力于提升农业知识产权创造、运用、保护、管理、服务能力,同时又要将绿色发展理念贯穿于政策制定、执行、评估、反馈、修订全过程。本文,首先对政策过程理论以及国内外农业知识产权发展相关文献进行分析,其次对农业政策进行评述,对其运行过程进行解析,最后结合上述分析研究农业知识产权绿色发展政策导向,提出了在“前、中、后”三段嵌入“绿色创新”、“绿色审查”和“绿色推广”的农业知识产权政策发展思路。  相似文献
