A method of valuating a patent using a multiple regression model, the method being implemented in a computer system comprising a patent information processor, a multiple regression analysis processor, a valuation model generating processor, and a patent valuation processor, the method comprising the steps of:
- acquiring and processing, by the patent information processor, objective evaluation criteria relating to patent information;
- separately performing, by the multiple regression analysis processor, a plurality of multiple regression analyses on the objective evaluation criteria in which a plurality of key valuation elements preset for a valuation index are dependent variables;
- calculating, by the valuation model generating processor, a representative value of a plurality of regression coefficients for each independent variable of a plurality of multiple regression models calculated through the plurality of multiple regression analyses;
- generating, by the valuation model generating processor, a valuation model for the valuation index by building a valuation model in which the calculated representative values are coefficients for the respective independent variables;
- and
- generating, by the patent valuation processor, a quantified valuation index of an issued patent which is a valuation target using the generated valuation model,
- wherein the separately performing of the plurality of multiple regression analyses comprises performing the multiple regression analyses, in which preset valuation elements are the independent variables of the multiple regression models, for the respective key valuation elements, and
- wherein the key valuation elements belong to the valuation elements, and a key valuation element is used as an independent variable of a multiple regression model for another key valuation element.
