Abstract The Intellectual Property Issue in the Sino-US Trade Friction since 2017 further highlights the urgency of increasing R&D investment and accelerating the pace of technological innovation in China.Patent competition has shifted from individual patent competition to patent portfolio competition.On the basis of literature review, this paper takes technical value, market value and legal value as the primary indexes for the evaluation of patent portfolio value.Based on the analysis of the characteristics of single patent and patent combination, combined with the characteristics of enterprise internationalization and patent standardization, the corresponding secondary indexes are proposed.Considering the subjectivity and fuzziness of decision makers, the dependence between evaluation indexes and the feedback mechanism, the value evaluation model of patent portfolio was constructed by using the fuzzy analytic network process (FANP), and the weight of qualitative and quantitative indexes was obtained through data processing.Finally, the model is calculated by using the actual data of patent combination.Therefore, it is believed that high-quality patent portfolio has significant contribution to enterprise value, and patent portfolio value is an important evaluation index of enterprise patent strategic performance.It is an issue to be studied to build a patent portfolio value evaluation model from the perspective of big data.
