碩士 === 國立中央大學 === 企業管理研究所 === 100 === To understand the core technologies of bicycle companies and their competitiveness in key technology fields, this study adopts the approaches of patent priority and patent portfolio to analyze the patent data collected from INPADOC and USPTO. The most recent litigated patent was identified first from LexisNexis. Core technologies of a bicycle company were then derived from the litigated patent by patent portfolio analysis. For the analysis of patent portfolio, patents having same IPCs as the core technologies were collected and examined. Besides, principal component analysis was applied on patent quality indicators to identify key patent portfolio subjects. Scatter plots were then pictured by country, company, domestic priority claim and forward citation from derived key patent portfolio subjects. From the findings of this study, bicycle companies not only acknowledge their technological development trend, but also understand their innovative performance in the disputed technological field.
