| Summary: | 碩士 === 國立清華大學 === 工業工程與工程管理學系 === 103 === In a competitive global marketplace, patents are used to claim the intellectual property right (IPR) and against the threat of litigation infringement from the competitor. On the other hand, some of non-practice entities (NPE) often use patents as a weapon to seek patent licensing and patent commercialization aggressively. For instance, in the mobile communication industry, there are many NPEs initiated patent lawsuits against manufacturer. A patent infringement lawsuit in the courts can be a very lengthy process, and the cost is extremely expensive. In order to avoid the NPE’s patent infringement litigations and understand the patterns of NPE's legal actions and the disputed patent trends, this research uses a NPE called “Wi-LAN” as an example and focuses on developing Modified Formal Concept Analysis (MFCA) approach to explore two levels of evolutions with respect to the IP infringement lawsuits and their disputed patents. Two MFCA models are constructed to observe the evolution of litigation and the disputed patents, the inter-related trends and developments. The disputed patents are grouped based on the common sets of disputed patents in the same group of litigations, and then illustrate the evolution progress of each group respectively. Finally, CPC classification is used to search the patents that similar with the disputed patents. The research provides the mobile communication manufactures with the analyses of related patents NPE holds to prevent infringement from re-occurring. Further, the research provides mobile communication industry with additional IPR references based on the litigation evolutions, the disputed patent trends, and their similar patents for future R&D directions and IP management strategies.
