The Application Of The Real Option Method Based On Binary Tree Model In The Valuation Of Patent Right

With the deepening promotion of the national intellectual property strategy,the number of patent applications in our country doubled and ranked first in the world.Patent right,as a key part of enterprise intellectual property,how to be valued has become an important part in the transformation of the achievement of intellectual property.With the increasingly frequent activities of patent transactions,a reasonable valuation method of patent rights is crucial for the economic activities such as patent investment,transfer transaction,pledge financing and external rights protection.Therefore,it is necessary to thoroughly study the method of appraisal of patent right value and fully realize the Economic and Social Benefits of Patent Value.At present,the research methods on the evaluation of the value of patent mainly use the traditional evaluation methods,ignoring the future investment value brought by the uncertainty of the patent,have certain limitations,and can not reasonably determine the value of the patent.In view of the real options of patent right,this paper uses the real option method to assess the value of the patent,with a view to provide more reasonable suggestions for the choice of the valuation method of the patent right in our country.This paper is divided into five parts.First of all,from the research background and significance of the research,this paper analyzes the research status of the real option and the real option in the evaluation of the value of the patent,and briefly introduces the main research contents,research significance and research methods.Secondly,on the basis of defining the concept of value assessment of patent right and patent right,this paper introduces the way to realize the value of patent right,analyzes the influencing factors of the value of patent right in detail,and makes qualitative analysis for the value evaluation of patent right.Then,on the basis of the theory of real options,this paper discusses the applicability of the real option method to evaluate the value of the patent by analyzing the option characteristics and the types of options contained in the patent options and establishes the binary tree patent value evaluation model.Then,the actual case is introduced to evaluate the value of patent rights by using the revenue-saving license fee saving method and the real option method,andthe two kinds of evaluation results are compared and analyzed.Finally,the paper summarizes the research contents,draws conclusions that real options method is more suitable for the patent value evaluation and points out the shortcomings and future research directions.
