Since the introduction of China's "Intellectual Property Strategy",the development of intellectual property rights and its influence in the national economy have received more and more attention.Especially in today's economic globalization,intellectual property rights have gradually become the core of international competitiveness.As a kind of intellectual property,patents play an increasingly important role in the development of China's economy.For enterprises,intellectual property plays a very important role in its competitiveness and its own development,and even affects its position in the entire industry.As a kind of intellectual property rights,patents should naturally attract the attention of enterprises.At the same time,with the rise of a large number of high-tech industries,the issue of protection of patent rights has begun to be valued by many companies.Moreover,as an asset,patent rights are gradually increasing.This makes the determination of the value of patents urgently require a solution.However,as an intangible asset,it is not like some tangible assets in terms of value determination.It has clear data support.Therefore,the question of how to determine the value of patent rights has been raised.The key to the determination of the value of patent rights lies in the choice of evaluation methods.Reasonable selection of evaluation methods is the basis for rational determination of patent rights.However,after selecting the evaluation method,the selection of parameters in the evaluation method model becomes the primary task.In the current method of evaluating patent rights,the income royalty method seems to be the most suitable and objective method.The parameters affecting the income royalty method are: expected return,technical royalty rate and discount rate.In the patent evaluation case selected in this paper,among the parameters of the expected income royalty method,the model for determining the discount rate has great subjectivity,which directly affects the determination of the evaluation result.Therefore,after a brief description of the evaluation case and its evaluation process,this paper improves the discount rate determination model,and uses the fuzzy level comprehensive evaluation method combined with the original discount rate model to determine the discount rate of patent rights,and then determine the patent.The result of the assessment of the right.The two results were compared and analyzed to make the evaluation results more accurate and objective.At the same time,it provides an idea for the selection of the patent discount rate model in the future.
