Pakes and Schankerman (1984), Schankerman and Pakes (1986) and Lanjouw (1998) have developed models in which the observed renewal decisions are used to estimate the distribution of patent values. A drawback of this approach is that it provides no indication of value differentials among those patents that are never renewed, and among those that are renewed to full statutory term. In addition, the accuracy of renewal behavior as an indicator of patent value depends on the extent to which imperfectly informed patent holders make rational decisions and act accordingly.

He found that the scope of patents has a significant and positive impact on the probability to create new technology-based firms. Overall, however, the empirical evidence on the relationship between patent scope and patent value is mixed at best.
