| Summary: | 碩士 === 國立交通大學 === 管理學院科技法律學程 === 99 === US patent litigation cases are increasing rapidly in the recent years. 861 types of IPC code H01L patents were involved in litigation during the period of 1990 to October of 2010. Although Taiwan companies have been applying for the U.S. patents aggressively， very few litigated H01L patents were owned by Taiwan companies. There are over thousands H01L patents granted to Taiwan companies in the past decade. It is necessary to find an efficient method to differentiate the value of H01L patents before conducting deteailed reviews on specific patents to serve litigation purpose.In this paper， litigated H01L patents were categorized into one-time litigatation and more than three-time litigation, repectively, for patent evaluation. The Z-test is employed to perform a statistical test for comparing the patent characteristics. There are significant differences among those patents that were litigated in different times. It is also found that although operating companies hold the majority of litigations to protect their market interests, the NPEs are aiming at multiple targets simultaneously by their patents..
