By drawing information from a survey of inventors of 9,017 European patents (PatVal-EU), this paper provides novel and detailed data about the characteristics of the European inventors, the sources of their knowledge, the importance of formal and informal collaborations among researchers and...

By using the PatVal-EU dataset we find that the most important determinant of patent licensing is firm size. Patent breadth, value, protection, and other factors suggested by the literature also have an impact, but not as important. In addition, most of these factors affect the willingness to...

This paper focuses on European small- medium serial innovators at the beginning of the 1990s and provides an empirical basis to answer the following questions: who are the upstream specialized small- medium technology producers? How are they distributed across countries? Are there technologies...

This paper focuses on European small- medium "serial innovators" at the beginning of the 1990s and provides an empirical basis to answer the following questions: who are the upstream specialized small- medium technology producers? How are they distributed across countries? Are there technologies...

Based on a survey of the inventors of 9,017 European patented inventions, this paper provides new information about the characteristics of European inventors, the sources of their knowledge, the importance of formal and informal collaborations, the motivations to invent, and the actual use and...
