Abstract

Strategic patenting is widely believed to raise the costs of innovating,especially in industries characterised by cumulative innovation. This paperstudies the effects of strategic patenting on R&D, patenting and marketvalue in the computer software industry. We focus on two key aspects:patent portfolio size which affects bargaining power in patent disputes, andthe fragmentation of patent rights (.patent thickets.) which increases thetransaction costs of enforcement. We develop a model that incorporates botheffects, together with R&D spillovers. Using panel data for the period 1980-99, we find evidence that both strategic patenting and R&D spilloversstrongly affect innovation and market value of software firms.
