| Tiivistelmä: | This paper models the effect of patent length on the rate-of-innovation and consumer welfare. The authors find that the patent length that maximizes the rate-of-innovation exceeds that which maximizes consumer welfare. The authors show a countervailing effect of patent length upon the "size" and "frequency" of innovation. Longer patents increase the size, but decrease the frequency of innovation. The patent lengths that maximize the rate-of-innovation and welfare represent balance points between size and frequency. |
