A Study <strong>of</strong> <strong>Patent</strong> <strong>Thickets</strong> 49<br />
Figures 10-12 provide a descriptive breakdown <strong>of</strong> entry by market sector in which firms are<br />
active. We assign each firm to a principal sector on the basis <strong>of</strong> information contained in a<br />
number <strong>of</strong> waves <strong>of</strong> the FAME data sets. These figures show that the business sectors giving<br />
rise to new entry into patenting most frequently change much less over time than the technology<br />
areas shown in Figure 7-9. Most entrants are active in Business Services, R&D services or<br />
Wholesale Trade.<br />
