Abstract:This paper analyzes the development status of patent evaluation from the perspective of evaluation tools. Based on a detailed introduction to the functions of common patent evaluation tools, the evaluation methods and indicators used by different tools are summarized, the development trend and existing problems of patent evaluation are discussed, and the corresponding suggestions are given. From a development perspective, the methods of patent evaluation are more intelligent and automated, more types of evaluation indicators with different evaluation dimensions are developed and the evaluation model is constantly optimized. However, domestic research on monetary value evaluation needs to be further improved. In the future, it is necessary to combine different evaluation methods and adopt the evaluation methods and evaluation systems according to the characteristics of the patent in different fields.
