Abstract: This paper identifies the prominent inventors (star scientists) in the Canadian biotechnology co-inventorship network by taking into consideration either only patent quantity or both patent quantity and quality. The paper studies the positions of these stars in the network structure and results show that inventors with a higher number of patents assume more central positions in the network: they have more collaborators, enjoy better access to information and also have greater control over knowledge flows in the network. Nevertheless, their network positions do not have higher levels of local cliquishness, suggesting that a clustered local neighbourhood may not have any positive impact on a scientist's innovative productivity. We also find that the majority of the stars play a knowledge gatekeeping role - nurturing clusters with knowledge originating outside. Finally, we examine and discuss the network dynamics and the role of these stars in the information transmission efficiency.
