The 'doing-using-interacting mode' of innovation (DUI) is considered an important component of innovative activity. It describes informal innovative activities and thus complements the 'science-technology-innovation mode' (STI) based on research and development. While empirical measurement of...

This paper proposes a search strategy for photovoltaic patents which allows to distinguish the photovoltaic system into sub-trajectories. Identifying and analyzing sub-trajectories is of particular importance for understanding micro patterns of technological change. The proposed search strategy...

Science-industry collaboration is one of the major channels for transferring new scientific ideas into economic applications. Whereas the factors leading to collaboration are reasonably well understood, the determinants of the outcomes generated by such collaboration are unknown. This paper...
