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...

In the literature there is a controversy about the relevance of the spatial dimension in innovation collaboration. We examine the link between the spatial composition of group members and group characteristics which are important for performing innovation projects. To this end, we introduce a...

The paper at hand investigates how co-patenting over distance develops when aggregating inventive activities on a regional level. That means, the object of analysis is a link between two regions in contrast to other studies, where links between two individuals or firms are investigated. We...
