Evaluation and Cultivation Method of High-tech Value Patents for Mechanical Products

Abstract

Abstract Evaluation of high value patents is essential for the enterprise's technical layout and innovative product design. The existing research on the patent value mostly focuses on the discipline of management and information science, which needs the support of a large number of professional statistical information and is difficult to directly reflect the technical value. Since technological innovation is the fundamental means to enhance the sustainable competitiveness of enterprises. Therefore, a high-tech value patent evaluation and cultivation method for engineering designers is proposed. Firstly, the indicators for evaluating technical value are summarized based on the induction of patent samples and patent technical features, and the rationality of the evaluation indicators is verifier through empirical study based on improved evidence theory. Secondly, based on principal component analysis and factor analysis, a high-tech value patent evaluation formula and cultivation method is proposed. Finally, the proposed method is applied to identify the high-tech value patents in the cutting machine industry. The proposed method provides a clear guiding direction for the cultivation of high novelty patents and enterprise innovative product design.
