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

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.
