A Study of Patent Thickets

This report analyses whether entry of UK enterprises into patenting in a technology area is affected by patent thickets in the technology area. The aim is to contribute to our understanding of the role of patent thickets as a barrier to entry into patenting for UK enterprises, in particular small and medium sized enterprises (SMEs). To do this we review the literature on patent thickets, discuss factors contributing to thicket formation and growth, and evaluate to what extent patent thickets might be considered to be barriers to entry in some technology areas.
