Internal sequential innovations: How does interrelatedness affect patent renewal?
The value of patented innovations has attracted substantial research attention, especially in the context of patent renewal. However, research often assumes that a firm's patented innovations are independent from each other. We draw upon evolutionary economics and suggest that some of a firm's patents share important genealogical relationships, which we refer to as internal sequential innovations. We propose internal sequential innovations are more valuable and therefore more likely to be renewed than stand-alone innovations. We examine our hypotheses from a dataset of US pharmaceutical and biotechnology patents. The results confirm our hypotheses at both the patent and the firm levels.
