| Abstract: | The stringency of novelty requirements that patent offers use in judging patentability defines the height of patent protection. The author studies patent height in a duopoly where firms compete in product improvements. A competitor who wants to invent around the other's patent is restricted by a minimum improvement level. The author shows that low patent protection does not affect market equilibrium without patent protection. A patent holder can lose with medium patent heights, but not if patents provide high protection. |
