This paper uses bibliographic coupling analysis to plot out a patent citation map. It explores the current research and development
in the high-tech electronic companies in Taiwan, and the relationship between companies and industries. Fifty-eight high-tech
electronic companies under this study, between 1998 and 2000, obtained 4162 patents from U.S., and cited 24,852 patents during
these years. Through the data from bibliographic coupling analysis, the paper categorizes these companies into 6 major groups:
semiconductor, peripheral, scanners, notebook / monitor, system, IC design / packaging. This research also uses multidimensional
scaling to plot out a patent citation map, graphically displaying the association among the groups. The result shows a higher
similarity among companies in semiconductor sector, whereas the distinction between industries grows more and more ambivalent,
even overlapping in some cases.
