Imitation versus Innovation Costs: Patent policies under common patent length
This paper investigates the interaction between innovation and imitation costs for heterogeneous ideas (industries). It analyzes the effect of various patent-related policies under the common patent length across different industries. It also looks at a policy that will strengthen trade secrets such as the Soleau envelope policy. Under the common term of patent with moderate assumption about the joint distribution of costs, the model predicts the existence of imitating products which are successfully invented around the original patent.
