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...

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...

The paper compares academic and corporate patents in Germany to shed light on the geographical distribution of the inventors. The residences of the inventors show different patterns in the two datasets. Furthermore, we analyze the spatial distance between inventors for patents invented in...
