Mit der zunehmenden Globalisierung wird der Wettbewerb heute auch für die Regionen spürbar. Damit diese den Anschluss an die internationale Weltmarktspitze nicht verlieren, müssen sie über ein leistungsfähiges regionales Innovationssystem verfügen. Gerade mit Blick auf den immer noch...

Theoretical considerations suggest that secrecy reduces spillovers almost completely through non-disclosure, while the disclosure requirement of patents generates some spillover and at the same time allows firms to appropriate knowledge. In this paper we empirically analyze whether protection by...

We analyze the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. Our central hypothesis states that technologies which become more...

Collaboration over distance is difficult to maintain in innovation projects which require a great deal of regional collaboration. However, patent documents reveal that a number of inventor teams are able to overcome long distances. Earlier literature started to investigate factors, which...
