Abstract
This study examines the consequences of inventor turnover for the termination of the patents they produced beforehand. The proponents of the knowledge-based view consider firms repositories of knowledge and inventors carriers of knowledge who create new inventions through recombination. I argue that because the knowledge about inventions resides with inventors, turnover among them may adversely affect the future use of their inventions due to the loss of tacit knowledge. As a result, firms are more likely to terminate the patents of inventors who have left than of inventors who remain. Further, the patterns of collaboration between departed inventors and others influence the above relationship. Analyses of the termination of patents, in the form of non-payment of renewal fees, by pharmaceutical firms support the claims in the paper. The findings have implications for how firms manage their knowledge portfolios in the face of inevitable inventor turnover and the resulting loss of tacit knowledge.
