一件專利的引用數通常被認為是一種涵蓋該專利之發明的價值或影響力指標。然而,專利申請案(特別是發明專利申請案)會在其經提出申請18個月後且在核准前這段期間公開。這種早期公開的申請案稱為公開案,公開案係為公開的資訊且會在其被核准之前和之後被後續申請之專利的申請人或審查人員作為相關的先前技術而引用。然而,大部分的專利分析僅考慮公告案的引用而忽略了其公開案的引用。公開案及其對應之公告案應涵蓋同一發明,這樣的漏計可能導致錯誤的分析結果。本研究藉由比較大約500,000筆的美國發明公告案及其對應公開案來評估此漏計的影響。統計顯示會有超過50%的專利會因漏計而被誤判,因此本研究建議當評價專利或進行專利引用分析時,分析者應該合併公開案及公告案的引用數量。
A patent's number of citations is often considered an indicator to the value or impact of the invention covered by the patent. However, patent applications, specifically utility patent applications, are published 18 months after filing and before they are granted a period of time later. These so-called pre-grant publications are public information and are citable as relevant prior art by the applicants or examiners of later patent applications before and after the pre-grant publications are granted. However, most patent analyses consider only the citations to the patents and ignore the citations to their pre-grant publications. This omission may lead to erroneous analytic result as the pre-grant publication and the corresponding patent cover the same invention. This study assesses the impact of such omission by comparing about 500,000 US utility patents and their pre-grant publications. The statistics shows that over 50% patents may be misjudged because of omission, suggesting that analyst should combine the citations to the pre-grant publications and to the patents together when evaluating patents or conducting patent citation analysis.
