Abstract：High-quality technology R&D work of patent is important to enhance the competitiveness of enterprises and maintain national industrial technology security.However,the current complex and changing technology evolution environment makes it difficult for enterprises to identify the technology direction with more future development prospects and to carry out effective patent R&D work.The existing methods of technology R&D direction selection for patenting mainly take the pan-technology domain as the research object,which is difficult to provide a clear direction for technology R&D of patent with finer granularity.At the same time,the endowment law of technology evolution is not sufficiently considered,so there is still room for improvement in the judgment of technology and market development trend.Therefore,this paper started from constructing a patent technology evolution knowledge graph,introducing technology evolution information,designed an analysis framework based on the evolution structure presented in the knowledge graph,and proposed evaluation indexes for identifying advantageous technology R&D direction for patenting in combination with technology life cycle theory.The proposed method further focuses the analysis perspective on technology R&D work of patent based on making full use of the law of technology evolution,and provides more precise and scientific direction guidance for technology R&D work of patent.At the end this paper conducted an empirical study in the field of technology of non-perfluorinated proton exchange membranes in China,which verifies the effectiveness of the proposed method and provides guidance suggestions for patent R&D.
