從專利引用與技術分類探討美國高科技公司之發展歷程與趨勢

Abstract

本計畫係利用專利引用網路探討 美國高科技公司研究領域和技術發展 之關係。研究方法將以五年為一時 段，統計高科技公司於1994 年至2003 年間在美國之核准專利分布情形；另 外，本計畫也應用書目計量學中之引 用分析法繪製專利引用網路，藉以呈 現公司研究領域與技術發展之關係。

This project attempts to analyze patent citation map and cluster by the relationship between American hi-tech companies. This study investigates the classification numbers of these companies’ issued patents during 1994 to 2003 to display their technology categories. Moreover, citation analysis will be a method to construct patent citation map with a period of five years. The results would provide a way to research their relationship and development.
