| Summary: | 碩士 === 國立成功大學 === 企業管理學系 === 106 === In many ICT (Information Communication Technologies) industries, firms develop innovative product technologies according to the technologies specifications under international standardization. However, under international standardization, firms are required to disclose their knowledge in order to collaborate with another firms to co-create product’s technological standards. On the other hand, in order to compete with other firms on the product market, firms have to increase and protect their intellectual property rights in product technologies. In other words, firms have to consider ways to manage their intellectual property rights in the different regimes of appropriability of standardized technologies and product market in the process of technology development. However, previous studies only discussed about the changes of a single regime of appropriability along with the evolution of the industry life cycle. Intellectual property rights in different regimes of appropriability weren't explored. Therefore, this study uses international standardization of telecommunication industry as the analysis objective, which is aimed to explain how firms use intellectual property rights in the weak regime of appropriability under international standardization to create intellectual property rights that are in the tight regime of appropriability in the product market. By analyzing the backward citations of firms’ proprietary patents citing from SEPs, we found that 1) the greater the quantity of technology knowledge in the weak regime of appropriability that firms have declared, the easier it is for other firms to assimilate and build up intellectual property rights under the tight regime of appropriability, 2) firms assimilate their or others’ intellectual property right which have been declared in the weak regime of appropriability to build up the intellectual property rights in the tight regime of appropriability. According to 1) and 2), this study argues that firms have to build up intellectual property rights in the tight regime of appropriability since firms can’t prevent knowledge spillover in the weak regime of appropriability.
