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...

Returns to Inventors

Toivanen, Otto; Väänänen, Lotta - C.E.P.R. Discussion Papers - 2010

A key input to inventive activity is human capital. Hence it is important to understand the monetary incentives of inventors. We estimate the effect of patented inventions on individual earnings by linking data on U.S. patents and their inventors to Finnish employer-employee data. Returns are...

Education and Invention

Toivanen, Otto; Väänänen, Lotta - C.E.P.R. Discussion Papers - 2011

Modern growth theory puts invention on the center stage. Inventions are created by individuals, raising the question: can we increase number of inventors? To answer this question, we study the causal effect of M.Sc. engineering education on invention, using data on U.S. patents’ Finnish...

On the price elasticity of demand for patents

de Rassenfosse, Gaétan; van Pottelsberghe de la … - C.E.P.R. Discussion Papers - 2008

This paper investigates whether patent fee policies are a potential factor underlying the boom in patent applications observed in major patent offices. We provide the first panel-based evidence suggesting that fees affect the demand for patents in three major patent offices (EPO, USPTO and JPO),...

Trade Secret Laws, Labour Mobility and Innovations

Motta, Massimo; Rønde, Thomas - C.E.P.R. Discussion Papers - 2002

We show that when the researcher’s (observable but not contractible) contribution to innovation is crucial, a covenant not to compete (CNC) reduces effort and profits under both spot and relational contracts. Having no CNC allows the researcher to leave for a rival. This alleviates a...
