| Abstract: | Based upon Dialog online search, we use Derwent World Patents Index (DWPI) and Derwent Patents Citation Index (DPCI) as data sources to analyze the patents in PEM fuel cell industry. This paper illustrates the skills of using various Dialog advanced commands for industry sector patents analysis. As a result, the industry sector leaders, pioneer experts, industrial foresight, global technology and market layouts, key technologies and recent R&D hot spots are discovered thereby. It has been shown that Dialog online search is an effective way for analyzing all the patents in an industry sector. |
