AB - Using 23,879 standard essential patents across three generations of mobile telecommunication technologies, we analyze technology and market characteristics of standard technologies. We collected standard essential patents from the ETSI online IPR database and matched the collected standard patent data with patent information from the European Patent Office patent database to form a set of analysis data. Analytic criteria include the type of firms, geographical features, the type of products, market positions of firms, and application year. Analysis implies strengthening competition for standard essential patents along with the evolution of standard technology. Mobile handsets and equipment manufacturers have the highest share of standard patents across all of its standard technologies, from the second to the fourth generation, and has steadily grown. In contrast, non-practicing entities did not have a high share, but their share growth was evident from the late 1990s when standardization began. Geographically, while the share of European firms decreased, the share of Asian firms has increased. The results of these standard essential patent analyses were similar to the major trends of firms in the mobile telecommunication market, indicating that the standard essential patent analysis can be an appropriate approach for analyzing the status and strategy of the firm's research and development.
