Innovationsanreize in einem strukturellen Oligopolmodell

Harhoff, Dietmar - 1997 - Revidiert: Februar 1997

In diesem Beitrag wird ein Oligopolmodell der Innovationsaktivität entwickelt und mit Daten aus dem Mannheimer Innovationspanel geschätzt. Das Modell erlaubt es, bei der empirischen Umsetzung auf die Verwendung von Marktanteilsdaten und Nachfrageelastizitäten zu verzichten, die typischerweise...

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...

Patent thickets, licensing and innovative performance

Cockburn, Iain (contributor); MacGarvie, Megan (contributor) - 2009

We examine the relationship between fragmented intellectual property (IP) rights and the innovative performance of firms, taking into consideration the role played by in-licensing of IP. We find that firms facing more fragmented IP landscapes have a higher probability of in-licensing. For firms...

The market value of blocking patent citations

Czarnitzki, Dirk; Hussinger, Katrin; Leten, Bart - 2011

shown that patents and their quality as measured by citations received by future patents contribute significantly to the … forward citations patents can receive at the European Patent Office. While a patent can be cited as non-infringing state of … the art, it can also be cited because it threatens the novelty of patent applications ("blocking citations"). Empirical …

Inventions under Siege? : the impact of technology competition on licensing

Grimpe, Christoph; Hussinger, Katrin - 2009

In recent years, firms have increasingly contributed to and been confronted with a patent landscape characterized by numerous but marginal inventions, overlapping claims and patent fences. Literature suggests that both the fragmentation of ownership and the threat of a firm's patent applications...

Giving away the game? : The impact of the disclosure effect on the patenting decision

Heger, Diana; Zaby, Alexandra K. - 2012

This article explores the propensity to patent in the light of the disclosure effect. Unlike earlier approaches concerned with the patenting decision, we take into account that a disclosure effect may decrease the merits of patenting by facilitating inventing around the patent for competitors....

Intellectual property infringements due to R&D abroad? : A comparative analysis between firms with international and domestic R&D activities

Schmiele, Anja - 2010

This paper aims at analysing the risk of intellectual property (IP) infringements by competitors from abroad and in particular whether this risk is higher for international innovating firms. We distinguish three different types of IP infringements from abroad: the usage of firms' technical...

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...
