Using the methods of network survey and literature review, the working mode and content of the Patent &. Trademark Resource Center (PTRC) in USA are systematically reviewed and the advantages of the service mode are analyzed and summarized. Then, taking the member library of PTRC, U niversity of Maryland Library as an example, an empirical research on the actual development mode of PTRC service in the member libraries is made, and the characteristics and features of the service are put forward. The domestic university libraries can learn from the experience of PTRC and its member libraries on aspects such as the establishment of patent service platform, the realization of resource sharing, thorough consultation and guidance, so as to explore the patent information service system suitable for Chinese university libraries.
