Study on Early Warning of Competitive Technical Intelligence Based on the Patent Map

Abstract

The patent documentation has a higher  technical value  than  the  general  scientific  documents.  Through analyzing  the  content  of  technical  intelligence  of  patent documentation,  enterprises  may  find  out  some  effective solutions,  having  access  to  new  ideas  about  Research  and Development (R&D) and avoiding existing patent landmines at  the  same  time.  In  this  paper, with  the  help  of  database Derwent  Innovations  Index  (DII)  and  the  corresponding software-Thomson Data Analyzer(TDA),  a  series  of  patent maps  of Web2.0  technologies  were  built  up  through  basic statistical  analysis,  trend  analysis  and  correlation  analysis. These patent maps could offer important reference value for the R&D activities of enterprises.
