|Graevenitz, Georg von and Wagner, Stefan and Harhoff, Dietmar (2009): How to measure patent thickets – a novel approach. Discussion Papers in Business Administration 2009-9|
This is the latest version of this item.
The existing literature identifies patent thickets indirectly. In this paper we propose a novel measure based on patent citations which allows us to measure the density of patent thickets directly. We discuss the algorithm which generates the measure and present descriptive results validating it. Moreover, we identify technology areas which are particularly impacted by patent thickets.
