Abstract

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 new technologies for UK enterprises, in particular small and medium sized enterprises (SMEs).

The report consists of several parts:

1) A review of the literature on patent thickets, including the limited empirical evidence regarding effects of patent thickets on R&D investments and competition;

2) Discussion of the factors contributing to thicket formation and growth;

3) An empirical evaluation of the extent to which patent thickets appear to be barriers to entry in some technology areas.

Keywords: Patents, thickets
