Patenting in the Shadow of Competitors
实证研究了不同诉讼成本的新生物技术公司的专利申请行为，发现高诉讼成本公司更少在竞争激烈的专利子类中申请专利，尤其是当竞争对手诉讼成本较低时。
This article empirically examines the patenting behavior of new biotechnology firms that have different litigation costs. I show that firms with high litigation costs are less likely to patent in subclasses with many other awards, particularly those of firms with low litigation costs. This pattern is consistent with the literature on costly litigation, which suggests that firms that have high litigation costs will take greater precautions to avoid litigation. These results are robust to a variety of control variables and modifications that seek to test alternative explanations. Copyright 1995 by the University of Chicago.
