Eine Big-Data-Analyse von Patentanmeldungen zeigt die Entstehungsorte deutscher Digitalisierungstechnologie. Leistungsstarke Cluster sind die süddeutschen Großstädte. Allein München bringt hierzulande jedes vierte Digitalisierungspatent hervor, mehr als jeder dritte Landkreis hingegen kein...

We examine the Nash equilibria of a game where two national governments set patent breadth strategically. Broader patents make R&D more attractive, but the effect on static efficiency is nonmonotonic. In a North.South model, where only the North can innovate, harmonization of patent breadth...

Since the patent system relies on private litigation for challenging weak patents, and patent settlements might influence the incentives for challenging patents, the question arises whether the antitrust assessment of patent settlements should also consider their impact on the incentives to...

Da Patente in der heutigen Wissensgesellschaft als Mittel zum Technologiehandel bzw. Technologietransfer zunehmend an Bedeutung gewinnen, stellt sich auch die Frage nach dem möglichen Handel der Patente selbst. Dennoch hat sich bislang kein organisierter Markt für Patente gebildet, obwohl ein...

The interplay between patents and standards in the information and communication technology (ICT) sector has been intensively debated at international, regional and national levels over the past decades. In essence, the debate is firstly about the extent and impact of patent holdup and holdout...

We use an exogenous change in German Federal law to examine how entrepreneurial support and the ownership of patent rights influence academic entrepreneurship. In 2002, the German Federal Government enacted a major reform called Knowledge Creates Markets that set up new infrastructure to...

This paper utilizes a data set of over 208,000 U.S. patents applied for between 1975 and 2010 to study development of strategic patenting over time and across industries. With received citations as a measure of patent social value, we use data envelopment analysis to estimate firm-level relative...

We propose a new patent-based measure of knowledge spillovers that calculates technological proximity based on firms that were identified via patent backward citations links. We argue that this measure has a couple of advantages as compared to the 'standard' measure proposed by Ja e: First, it...

Technological progress builds upon itself, with the expansion of invention in one domain propelling future work in linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its strength. Past innovation network structures are...

We study the prevalence and traits of global collaborative patents for U.S. public companies, where the inventor team is located both within and outside of the United States. Collaborative patents are frequently observed when a corporation is entering into a new foreign region for innovative...

We analyze the effect of patent thickets on entry into technology areas by firms in the UK. We present a model that describes incentives to enter technology areas characterized by varying technological opportunity, complexity of technology, and the potential for hold‐up in patent thickets. We...

This article empirically analyzes supply-side and demand-side factors expected to a.ect innovation in clean coal technologies. Patent data from 93 national and international patent offices is used to construct new firm-level panel data on 3,648 clean coal innovators over the time period 1978 to...

This article empirically analyzes supply-side and demand-side factors expected to affect innovation in clean coal technologies. Patent data from 93 national and international patent offices is used to construct new firm-level panel data on 3,648 clean coal innovators over the time period 1978 to...

Over time, the research has played a key role in the economic development reflected by the GDP growth, the increase of the patents' number, the volume of exports, the economic competitiveness of countries which have invested in research and development.The aim of this paper is to make a study at...

Seit einigen Jahren kann beobachtet werden, dass Unternehmen zunehmend marginale Innovationen in Patente umwandeln. Alle wichtigen Patentämter weltweit sind mit einer regelrechten "Explosion von Patentanmeldungen" konfrontiert (Harhoff et al., 2007). Die Rolle von geistigem Eigentum - englisch:...

This paper tests a number of hypotheses on the use and effectiveness of patents and trade secrets designed to protect innovation. While previous studies have often considered patents and trade secrets as substitutes for one another, we investigate the complementary role of the two protection...

Entrepreneurship in Japanese universities has changed radically over the last 15 years, following the introduction of an equivalent to the Bayh-Dole Act in 1999. However, it is still unclear whether Japanese entrepreneurship is working. There are some publications that focus on the...

We study the impact of social ties on the migration of inventors from East to West Germany, using the fall of the Iron Curtain and German reunification as a natural experiment. We identify East German inventors via their patenting track records prior to 1990 and their social security records in...

This paper considers the prospect of a government patent buyout in a model of endogenous growth. To this end, the author modifies a standard quality ladder growth model by incorporating possibility of imitation, and rent protection activities (RPAs) by the innovator. The government finances the...

Numerous empirical studies have analysed the influence of corporate taxation on the location of intangible assets within a company group. However, the previous literature has rather focused on studying the impact of taxation on patent location choices assuming that these assets represent the...

This paper investigates whether knowledge flows from host to source country as a result of migration, alleviating the negative effects associated with outward migration. Using a fixed effects Poisson regression, patent citations are used as a proxy for knowledge flows and regressed on...

The Europe 2020 Strategy has identified the key goal of smart, more inclusive and sustainable growth. In this direction, redirecting firms' innovation activities towards ecological targets without hampering their competitiveness is of paramount importance. The double externality issue related to...
