Theoretical considerations suggest that secrecy reduces spillovers almost completely through non-disclosure, while the disclosure requirement of patents generates some spillover and at the same time allows firms to appropriate knowledge. In this paper we empirically analyze whether protection by...

learning activities to generate successful products. Yet prior NPD research has largely taken a positivistic view of learning … despite an inkling that too much learning can lead to dysfunction. This study attempts to contribute the NPD literature by … analyzing whether and, if so, when technological learning engenders shortcomings and affects new product commercialization. We …

There are two important rules to patent races: minimal accomplishment necessary to receive the patent and the allocation of the innovation benefits. We study the optimal combination of these rules. A planner, who cannot distinguish between competing firms in a multistage innovation race,...

We develop a dynamic duopoly model of R&D competition to improve the quality of a finalgood. The innovation process is sequential and cumulative, and takes place alongside productionin an infinite-horizon setting. In this context we study the R&D incentive impacts resultingfrom a “research...

The paper analyzes a dynamic model of R&D investment with inter- and intrasectoral R&D spillovers, in which the profitability of an invention in one sector increases if there is an innovation in another sector. Interpreting intrasectoral R&D spillovers as a measure of intellectual property...

We examine the relationship between fragmented intellectual property (IP) rights and the innovative performance of firms, taking into consideration the role played by in-licensing of IP. We find that firms facing more fragmented IP landscapes have a higher probability of in-licensing. For firms...

From the viewpoint of an innovator a patent is a tradeoff between the right to exclude others from using the patented matter versus the requirement to disclose it. Given the sequential nature of many innovations, patent induced technology diffusion can spur technological progress. However,...

The 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...

This article investigates patent protection for a long sequence of innovations where firms repeatedly supersede each other. Incentives for R&D can be insufficient if successful firms earn market profit only until competitors achieve something better. To correct this problem, patents must provide...
