论文摘要
这项研究使用专利更新信息来估计技术和所有权状况的专利私人价值。专利价值是指发明人通过制造，使用或出售发明从专利中提取的经济奖励。因此，我们从专利权的角度衡量专利权（专利的私人价值）的价值。我们的经验分析包括1999年至2002年申请年度的555份专利。这些专利的期限在2018年结束，或由于续签费而失效。我们将专利权公司的续订决定模拟为订购的问题，其中专利更新费用随着专利的年龄而增加。诸如专利家庭规模，技术范围，发明人的数量和赠款滞后等变量被用作相应回归中的解释变量。因此，本文将专利权的续签决定与专利特征和更新成本计划相结合，以估算初始租金分配。我们发现，大量专利在早期阶段到期，几乎没有具有高价值的专利来证实使用欧洲，美国和中国数据的研究结果。正如预期的那样，某些技术级专利的估值高。
This study uses patent renewal information to estimate private value of patents by technology and ownership status. Patent value refers to the economic reward that the inventor extracts from the patent by making, using or selling an invention. Thus, we measure the value of patent right (private value of patent) from the patentee perspective. Our empirical analysis comprises of 555 patents with application year during 1999 to 2002. The term of these patents either ended in 2018 or lapsed due to non-payment of renewal fee. We model renewal decision of patentee as ordered probit where patent renewal fee increases with the age of patent. Variables such as patent family size, technological scope, number of inventors and grant lag are used as explanatory variables in the corresponding regression. Hence, this paper combines the patentee renewal decision along with patents characteristics and renewal cost schedule to estimate the initial rent distribution. We find that a large number of patents expire at an early stage leaving few patents with high value corroborating the results of studies using European, American and Chinese data. As expected, certain technology class patents enjoy high valuation.
