本研究提出一種新的專利分析方法,運用社會網路分析(Social Network Analysis)結合專利引證資料,實驗資料庫來源為USPTO美國專利資料庫。研究範圍以太陽能電池為例,以1987~2007為分析期間,使用UCINET工具軟體,加入以時間分隔及技術領域的概念成為時間分隔及技術領域連成的網路,藉此看出專利之間的關係,對專利分析工作有所助益。 研究結果顯示,過去的技術領域影響技術的發展趨勢,新技術多是在過去技術領域發展上的改良,轉做更新的技術領域較少機會;新技術的發展多數傾向於相同的國家,過去的技術領域和相同的國家在新技術發展趨勢在太陽能電池這個領域具有重要的地位。
This study propose a method of patent analysis,combine patent citation data applying Social network analysis,data source from USPTO(United States Patent and Trademark Office)database. Study period between 1987~2007,scope in solar cell,add the concept with technology field and time separate,become a network linking by time and technology field,using by UCINET software tools,through this way find out relation between patent,and helpful to patent analysis work. The result present past technology field effect technology trend,most past technology field modified by new technology, and few chance transfer to do innovation field;Most new technology field intend to same country,technology in the past and in the same country has import position on solar cell technology field.
