Abstract: 【Purpose/significance】Build a data-driven patent information precision service framework for university libraries，explore a data-driven patent precision service model，and help university libraries carry out patent information services from a more system⁃atic perspective【. Method/process】Combined with the patent service content provided by the existing university library，with the help of data-driven power concept and big data technology，this paper puts forward the framework model of data-driven patent information accurate service system of university library【. Result/conclusion】Improve the patent information precision service mode of university library，strengthen the important role of data driving in the patent information precision service of university library，and provide new
ideas for the construction of patent information precision service system of university library【. Innovation/limitation】As the patent in⁃formation precision service of university library is still in the exploration stage，it also needs the active participation and discussion of university scientific research teams，university libraries and enterprises in practical application.
