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:
- A review of the literature on patent thickets, including the limited empirical evidence regarding effects of patent thickets on research & development investments and competition;
- Discussion of the factors contributing to thicket formation and growth;
- An empirical evaluation of the extent to which patent thickets appear to be barriers to entry in some technology areas.
