802.11標準必要專利之專利品質之分析與研究

Abstract

本論文之目的在於藉由美國專利申請案資料庫（U.S. Patent Application Database），以分析802.11標準必要專利之專利特性，而評估802.11標準必要專利是否比非802.11標準必要專利具有較佳之專利品質。多重的專利指標被用來進行分析，這些指標包括：向前引用次數、向後引用次數、非專利參考文獻引用次數、專利家族的數量、請求項的數量、發明人人數、審查時間、專利維護比率、主張臨時案優先權比率以及涉及訴訟比率。 本論文研究發現，802.11標準必要專利與非802.11標準必要專利在下述多重專利指標變量具有統計學上顯著性差異：（1）向前引用次數、（2）向後引用次數、（3）專利家族的數量、（4）審查時間、（5）維護專利之比率、（6）涉及訴訟之比率；本章研究結果並發現，802.11標準必要專利及非802.11標準必要專利在下述4個多重專利指標變量並不具有統計學上顯著性差異：（1）非專利參考文獻引用次數、（2）請求項的數量、（3）發明人之數量、（4）主張臨時案優先權之比率。 基於以上之發現，本論文結論為802.11標準必要專利相較於非802.11標準必要專利確實具有較好的專利品質。

The object of this study is to use the US Patent Application Database to identify the characteristics of IEEE 802.11 stadard essential patents to determine whether 802.11 stanard essential patents have better patent performance than non-802.11 standard essential patents. Multiple indicators are used to analyze the issue. These indicators include: the number of forward citations, the number of backward citations, the number of non-patent references, the number of patent families, the number of claims, the number of inventors, the examination time, the maintained rate, the rate of claiming priority from a provisinaol application and the rate of involving litigations. It is found that there are statistically significant differences for the two types of patents in the following seven variables: (1) number of forward citations, (2) number of backward citations, (3) number of patent families, (4) examination time, (5) maintained rate, and (6) rate of involving litigations. It is also found that there are no statistically significant differences for 802.11 stanard essential patents and non-802.11 standard essential patents in the following three variables: (1) number of non-patent references, (2) number of claims, (3) number of inventors, and (4) the rate of claiming priority from a provisinaol application. Accordingly, it is concluded that 802.11 standard essential patents have better patent performance than non-802.11 standard essential patents.
