About the Seminar: How do firms and inventors move through knowledge space as they develop their innovations? In this seminar, Vasco M. Carvalho proposes a method for tracking patterns of exploration and exploitation in patenting behaviour in the US for the period since 1920. The exploration measure is constructed from the text of patents and involves the use of Bayesian Surprise to measure how different current patent-based innovations are from existing portfolios. Results indicate that there are distinct life-cycle patterns to firm and inventor exploration. Furthermore, exploration activity is more geographically concentrated than general patenting, but this concentration is centered outside the main hubs of patenting.
