Abstract: The technological similarity among enterprises is an important content of enterprises’ technological intelligence analysis. Approach and process for technological similarity analysis for enterprises based on patent coupling is raised, in order to supply enterprises with effective decision-making information and help enterprises to search for technology competitive and cooperative objects worldwide. First, this paper compares some relate approaches in previous studies and points out that patent coupling analysis is a more accurate and real-time approach for reflecting technological similarity among enterprises. Secondly, the paper improves the method for calculating the coupling strength of the paired enterprises based on elaborating the principles of patent coupling analysis, in order to effectively distinguish the difference of coupling strength among several coupling pairs. Thirdly, the paper construct a visualization and application process framework for analyzing technological similarity among enterprises, through applying correlation analysis and multiple-dimension scaling based on the coupling data. Finally, this paper reveal the technological similarity among the primary organizations in the field of flat panel display, it further demonstrates the visual analysis and application process of enterprises’ technological similarity analysis based on patent coupling and can provide a guide for enterprises’ technology intelligence analysis.
