Abstract:In recent years, the business volume of patent pledge loan has increased rapidly. In this kind of business, A thorny problem that commercial banks need to solve is how to select high-quality patents as the pledge object. Taking the quality connotation of pledged patents as the starting point, this paper constructs a quality evaluation system including legal dimension, technical dimension and enterprise dimension, and uses support vector machine algorithm to improve the evaluation efficiency. At the same time, the scenario analysis method is introduced to obtain the dual scenario valuation of the pledged patent, and the quality evaluation results are used to modify the evaluation value. Finally, the chip patent of RX enterprise is selected as the research case, and the evaluation model constructed is used to evaluate the pledge value of chip patent, which verifies the applicability of the model in the evaluation of pledge patent value.
