| Tiivistelmä: | In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a non-infringing innovation displaces its product in the market. The authors define the length of time until one of these happens as the effective patent life, and show how it depends on patent breadth. The authors distinguish lagging breadth, which protects against imitation, from leading breadth, which protects against new improved products. |
