Assessment of the Connectivity between Technologies Based on Patent Co-classification

Huang Bin;Huang Lucheng;Wu Feifei;Miao Hong;School of Economics and Management,Beijing University of Technology;  
The paper proposes a method to assess the connectivity between individual technology and other technologies based on patent coclassification.The method firstly retrieves the corresponding patent data via patent co-classification,then constructs the fuzzy sets of the connectivity between technologies;lastly,assesses the connectivity between individual technology and other technologies using some properties of fuzzy sets.Taking international patent classification(IPC)code F03C(the technology of positive-displacement engines driven by liquids)as the research target,the paper conducts an empirical analysis on the method through the corresponding patent data from Derwent Innovations Index(DII).The empirical results show that there are differences in relationships between the technology of IPC code F03 C and other technologies,and the F03 C technology is fuzzy to some extent.The proposed method is proved to be feasible and effective.It also can offer academic reference to identifying the connectivity between technologies.
