SHEN Jun1,2 WANG Xukun1 GAO Jiping1 TENG Li1 LIN Deming1(1.WISE Lab,Institute of Science Studies and S&T Management,Dalian University of Technology,Dalian 116023; 2.Business School,Shandong University at Weihai,Weihai 264209)  
In the field of mobile communication,it is critical to get the potential information by the patent indicator analysis for the firm's RD and innovation,especially in key technologies' identification.Taking Derwent Innovation Index as the database,the paper chose 16,759 patent documents from 1994 to 2009 to analyze the key technologies in the field.After the construction of indicators,including frequency,centrality,burst and Σ,the manual codes indicating key technologies were identified with the CiteSpace.At last,based on the indicators,the key technologies in different period were revealed in the patent map.
