This paper introduces the design and implementation of a patent information acquiring and analysis prototype system. Patent search keywords in a certain domain are expanded by way of concept retrieval, which improves the search performance. Meanwhile, patent text information from Web pages of search results are accurately parsed and extracted by XML technology. Finally, the system applies social network analysis method to patent citation analysis.
