摘要
传统的专利价值评价方法没有考虑专利投资的实物期权价值,存在很大的缺陷,即低估专利的价值。目前用实物期权来评估专利价值的文献又没有考虑技术进步对专利价值的影响,从而高估专利的价值。为了准确评估专利的价值,本文将考虑技术进步对专利价值的影响,用跳-扩散过程来描述技术进步过程。通过介绍专利评估的实物期权方法,再对不考虑技术进步时专利评估的实物期权方法和存在技术进步时专利评估的实物期权方法进行详细的介绍,并对有竞争条件和无竞争条件下专利的实物期权价值进行比较,从而提高引入技术进步来评估专利价值的准确性。
Traditional methods of patent pricing do not consider real option valuation of the patent,leading to the undervaluation of the patents. However, now, the research that applies real option to patent pricing does not consider the impact of rivalry entry on the value of patent option, leading to the overvaluation of the patents. In order to price patents accurately, in considering the effect of rivalry entry on the value of patent option, a real option approach for patent pricing is proposed. This method is applied to analyze the patent pricing with technological progress considered and with technological progress not considered, respectively, for comparison. Also, with competition and without competition, the valuation of patent real option is analyzed. Results show that, in considering the technology progress, the proposed method can accurately price the value of patents.
