It is found 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. Expand
Measuring Patent Value Indicators with Patent Renewal Information
This paper attempts to fill a research gap of literature by constructing the dynamic model into which both ex ante and ex post patent value indicators are incorporated. A patent renewal model isExpand
The Relationship between Patent and Second Tier Patent Protection: The Case of the Dutch Short-Term Patent System Abolition
While the effect of changes in patent protection strength on innovative activity has been studied extensively, the role of second tier patent protection in national innovation systems has been aExpand
The Disciplinary Effect of Post-Grant Review - Causal Evidence from European Patent Opposition
We study the causal impact of invalidating marginally valid patents during post-grant opposition at the European Patent Office on affected inventors’ subsequent patenting. We exploit exogenousExpand
Patent Quality: Towards a Systematic Framework for Analysis and Measurement
Abstract The quality of novel technological innovations is extremely variable, and the ability to measure innovation quality is essential to sensible, evidence-based policy. Patents, an often vitalExpand
Patterns of Innovation During the Industrial Revolution: A Reappraisal Using a Composite Indicator of Patent Quality
The distinction between macro- and microinventions is at the core of recent debates on the Industrial Revolution. Yet, the empirical testing of this notion has remained elusive. We address this issueExpand
Counting standard contributions to measure the value of patent portfolios - A tale of apples and oranges
Abstract Measuring the value of portfolios of Standard-Essential Patents (SEP) is a difficult and controversial exercise. It has recently been suggested to use counts of technical contributions toExpand
Innovating by eliminating: Technological resource divestiture and firms’ innovation performance
Abstract While much of the prior research focused on the acquisition and accumulation aspect of technological resources, this study turns attention to a firm’s decision to divest its technologicalExpand
Ex-ante measure of patent quality reveals intrinsic fitness for citation-network growth
We have constructed a fitness parameter, characterizing the intrinsic attractiveness for patents to be cited, from attributes of the associated inventions known at the time a patent is granted. ThisExpand

When Do More Patents Reduce R&D?
This paper develops a simple duopoly model in which investments in R&D and patents are inputs in the production of firm rents. Patents are necessary to appropriate the returns to the firm's own R&D,Expand
The Value of U.S. Patents by Owner and Patent Characteristics
This paper uses renewal data to estimate the value of U.S. patents, controlling for patent and owner characteristics. Estimates of U.S. patent value are substantially larger than estimates forExpand
