摘要: | 本研究目的乃在於設定一個專利分類準則,用以辨別專利的重要性與價值。其中,書目計量學(Bibliometrics)之布萊德福法則(Bradford’s Law)提供了一個實證方法,本研究得以藉此法則探索此種分類法則,同時亦發現在專利被引用(forward citation)資料中,存在了一個不均勻分佈(unequal distribution)。此外,藉由三個產業的實證研究當中,也發現了專利被引用資料的分佈中存在葛羅斯偏垂(Groos droop)現象,如同書目計量研究,說明了專利被引用中亦有大量專利鮮少被引用的狀況。
專利資料的分散現象在本研究中,藉由圖形發展來探究其成長現象。更進一步地,藉由計量性的探討,基於布萊德福法則下將各產業專利資料分區,並在各產業中進行比較,發現本研究之三個產業專利被引用分佈,具有相同的成長分佈。 最後,本研究亦提出相關的管理意涵,建議公司應專注於自身落在專利分區的第一區專利技術,因其具有相對的發展價值。而建議未來研究方向,則應該專注於這些較具有價值性的專利資料。此外,後續相關於專利之研究變數,也建議參考本研究之專利價值分類準則。而布萊德福法則亦可作為專利資料的整體技術管理方法。 The objective of this research is to set up a criterion for classifying the patents by their importance and value. Bradford’s law provided a practical method for us to find this criterion and verified the unequal distribution of patent data related to forward citation. Groos droop was also verified which presented in the industries studies that revealed there would be a rule of higher number of patents containing fewer forward citations. The meaning of patent data scattering was also deeply elaborated and illustrated in some growing patterns. Based on more numerical discussion, it was more precisely depicted that how the distributions in several zones of patent data grew which Bradford was mentioned in the industrial studies. Meanwhile, the comparative discussions on the patent data distributions of three industries were also verified that there would be the similar trends among them. The managerial implication was discussed in the study as well. It was emphasized that a firm should have more of the patent belonged to the first zone and make effort to focus on the development of the relative technology. The future works were supposed that using the valuable patents, the first zone’s patents, was more meaningful than the numerical count of all the patents. Therefore, the other studies about the prediction of firm’s performance could modify the independent variable according the criterion made from Bradford. Besides, taking the entire firm’s granted patents as a Bradford curve to see the overall development pattern was also a technological development method. |
