ABSTRACT

Objective To investigate the patent technological domain distribution of shanghai health system,and comparative analysis of patent technological hotspots between shanghai health system and enterprises.Methods The study used IPC classification method to conduct quantitative analysis of the distribution of patent technology,co-words analysis and visualization of social network establishment method were adopted to analyze patent technological hot spots.Results Within the A61 category,numbers of authorized patents of shanghai health system in orders are A61B、A61K、A61M and A61F.Further analysis of the highest authorized A61B17 group patent in the highest class A61B found that,compare to enterprises,the degree of coincidence with the high-frequency keywords of the technology hotspots is small,the technical hotspots are scattered,and lack of overall technical arrangement.Conclusions Shanghai health system mainly focused on medical device development.It is lower than that of enterprises regarding to the patent technology market demand matching,technical arrangement of the enterprise is relatively better than the health system,thus,the study suggested enhancing market demand survey,adjusting patent distribution,and broadening the scope of market promotion.
