Abstract:China"s economy has shifted from a stage of high-speed growth to a stage of high-quality development, and high-quality development needs the escort of high-value patents. The evaluation of high-value patents is an important link to promote the transformation of high-value patents into real productivity. In order to effectively evaluate high-value patents, firstly, we defined the connotation of high-value patents, secondly, we analyzed and evaluated the existing methods of patent value evaluation, and then we took 300 Chinese Patent award-winning patents as the research object, from four aspects: technical factors, legal factors, economic factors, and market factors, to explore the typical features of high-value patents, build the evaluation index system and evaluation model of patent value. Through verification, it is found that the model has high accuracy, good measurability, and strong practicability, which can provide reference for accelerating the evaluation of high-value patents and promoting the cultivation and transfer of high-value patents. Finally, in response to the evaluation of high-value patents, countermeasures and suggestions were put forward on improving the evaluation system, enhancing the evaluation awareness and ability, and building an evaluation service platform.
