The Rough Set Based Approach to Risk Categorization of Patent Infringement

[[abstract]]專利侵權風險是現今企業所關心的話題之一，特別是在這個智慧財產權日漸被重視的時刻。如果企業失去對所擁有的核心專利做保護的動作，那麼不只是失去商品上的利潤，還會失去產業的競爭力。然而，目前的專利侵權的研究多為關注在於去找出跟科技趨勢有關的指標或是去計量專利的最終價值。但是，較少的研究者關注在用分類的機制去分析專利的侵權風險類型。例如，收集專利侵權的案例，取得被侵權專利的顯著屬性，接著利用屬性來推導出一套跟專利侵權相關的決策規則。因此，本研究提出以約略集合理論 ( Rough Set Theory ) 為基礎結合概念階層和信賴指標來進行專利資訊分析，找出侵權專利之顯著屬性以歸納決策規則用於侵權風險的分類。[[abstract]]Patent infringement risk is significant issue in the corporation because of increasing appreciation in the intellectual property rights recently. If corporation ignores the protection of the patent, it may not only lost profit in the product, but also lost the industry competitiveness. Much studies on patent infringement, which major focus on measuring the patent trend indicator and the patent monetary value. However, only fewer researches attempt to develop a categorization mechanism for the patent infringement risk, for example, the categorization of the patent infringement cases, then determine the significant attribute, and induction the infringement decision rules. In the study, the rough set theory (RST), which is suitable for processing qualitative information, is applied to induct rule to derive significant attribute for decision making of categorization to patent infringement risk. Through concept hierarchical and credible index is improving the evidence of the final decision rules.[[note]]碩
