linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its … strength. Past innovation network structures are calculated using citation patterns across technology classes during 1975 … predictive power on future innovation after 1995. This pattern is consistent with the idea that when there is more past upstream …

The R&D-patent relationship: An industry perspective

Danguy, Jérôme; de Rassenfosse, Gaétan; van … - In: EIB Papers 14 (2009) 1, pp. 170-195

This paper re-visits the empirical failure to establish a clear link between R&D efforts and patent counts at the industry level. It is claimed that the 'propensity-to-patent' concept should be split into an 'appropriability propensity' and a 'strategic propensity'. The empirical contribution is...

Productivity and Propensity : The Two Faces of the R&D-Patent Relationship

de Rassenfosse, Gaétan - 2011

This paper tackles one of the most persistent criticism of patent statistics. Because not all inventions are patented, the patent-to-R&D ratio reflects both a productivity effect (the number of inventions created per unit of research input) and a propensity effect (the proportion of inventions...

Selection Bias in Innovation Studies : A Simple Test

de Rassenfosse, Gaétan - 2013

The study of the innovative output of organizations often relies on a count of patents filed at one single office of reference such as the European Patent Office (EPO). Yet, not all organizations file their patents at the EPO, raising the specter of a selection bias. Using novel datasets of the...

Econometric Evidence on the Depreciation of Innovations

de Rassenfosse, Gaétan - 2017

This paper presents estimates of the depreciation rate of innovations using survey data on revenues associated with Australian patents. Its novelty is twofold. First, it relies on direct observation of the revenue streams of inventions. This is in sharp contrast with previous studies, which all...

The Economics of Patent Backlog

de Rassenfosse, Gaétan - 2016

Patent offices around the world face massive backlogs of applications, which threatens to slow down the pace of technological progress. However, economists lack analytical tools to tackle the issue. This paper provides a model of patent backlogs inspired by the literature on traffic congestion....

Do patent pledges accelerate innovation?

de Rassenfosse, Gaétan; Palangkaraya, Alfons - 2021

This paper estimates the effect of patent pledges, commitments made voluntarily by patent holders to limit the enforcement of their patents, on follow-on inventions. Patent pledges have been gaining popularity in recent years thanks to the highly visible pledges of companies such as Google and...
