dc.description.abstractThe traditional argument that shorter product cycles favor trade secret over patenting is reviewed. A game theoretic model provides an argument that shorter product cycles can induce firms to file more patent applications. The firms may be trapped in a prisoners' dilemma where all firms would jointly prefer to patent less and to not have a patent thicket. If firms start applying for patents on technologies which are not yet mature in order to cover ideas that may eventually turn successful, this may create a patent thicket. The transition into a situation where firms start patenting many ideas instead of single mature technologies is initiated and accelerated when network effects are present or patents exhibit a blocking property.en_US
