Exploring the tail of patented invention value distributions

Harhoff, Dietmar; Scherer, Frederic M.; Vopel, Katrin - 1997

We explore the tail of patented invention value distributions by using value estimates obtained directly from patent holders. The paper focuses on those full-term German patents of the application year 1977 which were held by West German and U.S. residents. The most valuable patents in our data...

New evidence on determinants of IP litigation : a market-based approach

Czarnitzki, Dirk; Criekingen, Kristof van - 2018

We contribute to the economic literature on patent litigation by taking a new perspective. In the past, scholars mostly focused on specific litigation cases at the patent level and related technological characteristics to the event of litigation. However, observing IP disputes suggests that not...

Do trademarks diminish the substitutability of products in innovative knowledge-intensive services?

Crass, Dirk; Schwiebacher, Franz - 2013

Trademarks are often supposed to reduce substitutability and imitability of product innovations. Using German CIS data for 2010, we provide empirical evidence that trademarking firms assess easy product substitutability as less characteristic for their competitive environment. This is...

Attenuation bias when measuring inventive performance

Zwick, Thomas; Frosch, Katharina - 2016

Most previous results on determinants of inventive performance are biased because inventive performance is measured with error. This measurement error causes attenuation bias. More specifically, for example age and education as drivers of patenting success have biased coefficients and too high...

Innovation dynamics and endogenous market structure : econometric results from aggregated survey data

Gottschalk, Sandra; Janz, Norbert Helmut - 2001

This paper examines empirically the relationship between innovation and market structure within a simultaneous framework at the industry level of aggregation. We use a model in which R&D affects both, demand and cost conditions. An optimization process leads to optimal industry R&D expenditure...
