However, its output format is limited, and includes patent abstract only. This article designs a distributed Derwent patent extraction system based on multi-agent platform. With it, the patents information is imported into a local database, and the detail information in USPTO can also be acquired. The system is effective,and this study is contributed to make a good information acquisition method for patent research.
