| Tiivistelmä: | This paper develops a simple model of sequential innovations with a diversity of research lines. Competitive strategies of firms for R&D are analyzed at each stage in a sequence of innovations. The author compares two alternative regimes of enforcing patent law, as a mechanism to provide adequate incentives for R&D at each stage. The regime that protects the research line gives monopoly rights to an entire line of research, hence limiting the utilization of the previous knowledge and retarding subsequent innovations. |
