摘要：
This paper reports the results of an analysis of patent citation and patent renewal data, advancing a log-linear relation between patent citations and patent value. A complementary analysis of firms' patent portfolios confirms that modelling the relation between citations and firm value benefits from the adoption of the log-linear form.
