A Brief History of Space and Time: the Scope-Year Index as a Patent Value Indicator Based on Families and Renewals

van Pottelsberghe de la Potterie, Bruno; van Zeebroeck, … - C.E.P.R. Discussion Papers - 2007

The renewal of patents and their geographical scope for protection constitute two essential dimensions in a patent’s life, and probably the most frequently used patent value indicators. The intertwining of these dimensions (the geographical scope of protection may vary over time) makes their...

The Value of European Patents

Gambardella, Alfonso; Harhoff, Dietmar; Verspagen, Bart - C.E.P.R. Discussion Papers - 2008

skewed distribution of patent values. Our measure is significantly correlated with the number of patent citations, references …, claims, and countries in which the patent is applied. Citations explain value as much as the other three indicators combined …, and the right tail of citations is correlated with the right tail of our value measure. Yet, the four indicators only …

Claiming More: The Increased Voluminosity of Patent Applications and its Determinants

Guellec, Dominique; van Pottelsberghe de la Potterie, Bruno - C.E.P.R. Discussion Papers - 2006

The joint increase in the number and size of patents filed around the world puts the patent system under pressure. This paper analyses the sources of this surge in number of claims and pages of patent applications at the EPO. Four hypotheses are scrutinized: the diffusion of national drafting...

Strategic Patenting and Software Innovation

Noel, Michael D.; Schankerman, Mark - C.E.P.R. Discussion Papers - 2006

Strategic patenting is widely believed to raise the costs of innovating, especially in industries characterised by cumulative innovation. This paper studies the effects of strategic patenting on R&D, patenting and market value in the computer software industry. We focus on two key aspects:...

Improved JIVE Estimators for Overidentified Linear Models with and without Heteroskedasticity

Ackerberg, Daniel; Devereux, Paul J. - C.E.P.R. Discussion Papers - 2008

We introduce two simple new variants of the Jackknife Instrumental Variables (JIVE) estimator for overidentified linear models and show that they are superior to the existing JIVE estimator, significantly improving on its small sample bias properties. We also compare our new estimators to...

Waiting to imitate: on the dynamic pricing of knowledge

Henry, Emeric; Ponce, Carlos - C.E.P.R. Discussion Papers - 2009

We study the problem of an inventor who brings to the market an innovation that can be legally copied. Imitators may 'enter' the market by copying the innovation at a cost or by buying from the inventor the knowledge necessary to reproduce and use the invention. The possibility of contracting...
