On the origins of the worldwide surge in patenting: An industry perspective on the R&D-patent relationship

Résumé

This article decomposes the R&D-patent relationship at the industry level to shed light on the sources of the worldwide surge in patent applications. The empirical analysis is based on a unique data set that includes five patent indicators computed for 18 industries in 19 countries covering the period from 1987 to 2005. The analysis shows that variations in patent applications reflect not only variations in research productivity but also variations in the appropriability and filing strategies adopted by firms. The results also suggest that the patent explosion observed in several patent offices can be attributed to the greater globalization of intellectual property rights rather than to a surge in research productivity.

A policy insight into the R&D-patent relationship

Gaétan Jean A de Rassenfosse

Contrary to an accepted wisdom, this paper shows that cross-country variations in the number of patents per researcher do not only reflect differences in the propensity to patent but also signals differences in research productivity. We put forward and test an empirical model that formally accounts for the productivity and the propensity component of the R&D-patent relationship. The two components play an important role, as witnessed by the impact of several policies, including education, intellectual property and science and technology policies. Indicators based on domestic priority filings reflect research efforts and are primarily affected by varying propensities to patent. In contrast, international filings, especially triadic patents, rather capture variations in research productivity. © 2008 Elsevier B.V. All rights reserved.

Do firms face a trade-off between the quantity and the quality of their inventions?

Gaétan Jean A de Rassenfosse

This paper presents evidence that firms face a trade-off between the quantity and the quality of their research output. The econometric analysis uses survey data on patent applicants at the European Patent Office and addresses the identification problem caused by differences in firms' propensity to patent. The existence of a trade-off emphasizes the need to take the quality of research output into account when assessing research productivity. It also raises questions about the optimal quantity-quality mix that firms should target. Â© 2013 Elsevier B.V. All rights reserved.

Why do patents facilitate trade in technology? Testing the disclosure and appropriation effects

Gaétan Jean A de Rassenfosse

Evidence suggests that patents facilitate technology transactions but the reasons for the effect are unclear. Patents may assist trade in technology by either: (i) protecting buyers against the expropriation of the idea (the 'appropriation effect'); or (ii) increasing information sharing during the negotiation phase through publication of technical details contained in the patent document (the 'disclosure effect'). We estimate the strength of both effects using exact matching analysis on a novel dataset of 860 technology transaction negotiations. We find evidence for the appropriation but not the disclosure effect. Technology transaction negotiations involving a granted patent instead of a pending patent (our test for the appropriation effect) are significantly more likely to be successfully completed. The appropriation effect is stronger in technology fields where patent protection is known to be more effective such as biotech, chemicals, drugs and medical. (C) 2016 Elsevier B.V.
