在一些高科技领域中,过多的授予不同权利人专利权会导致专利权“片段化”问题的出现,这种“专利分散”现象会造成企业进一步创新和生产产品要支付过多的阻碍专利许可费,增加了企业的成本负担。为了研究专利分散对创新及企业效益的影响机理,本文构建博弈模型进行分析,研究结果表明:“专利分散”所导致的阻碍性专利的增加会使得企业利润缩小,消费者剩余下降从而影响到社会福利,给市场竞争带来负面效用。最后,结合博弈分析,提出了相关政策建议。
In some high-tech fields, too many patent rights granted to different proprietors will lead to the emergence of the “fragmentation” of patent rights. Such “patent diversification” will cause enterprises to make further innovations and pay for the production of products Hinder patent licensing fees, increasing the cost burden on the business. In order to study the mechanism of the impact of patent decentralization on innovation and enterprise efficiency, this paper constructs a game model to analyze the results. The results show that the increase of obstructive patents caused by “patent diversification” will result in the reduction of corporate profits and the decline of consumer surplus To social welfare, to bring negative competition to the market. Finally, combined with the game analysis, put forward the relevant policy recommendations.
