English-Language Version

The English-language version of the Wanfang Data portal includes a drop-down menu in the upper right corner of the website, where users can select to access databases individually. User can also search through a cross-database search form, where users select any or all of nine different databases via checkboxes in a side menu. The Cross-Database Search includes three query forms (with a drop-down menu of field identifiers: full text, title, author, institution, etc.) that can be connected by Boolean operators (via a drop down menu between query forms).  In order to conduct any searches within the English-language version of the portal, users must first sign in to their subscription-based accounts.

The English-language version of the Wanfang Data website describes each database available through the platform:

Conclusion

Wanfang Data includes content and search options for both Chinese and English-language users, and although the content is subscription-based, users can still search the portal and view limited records through the Chinese version of the system.  The portal gives users access to an impressive array of Chinese patent and non-patent literature, ranging from journal articles to company listings and industrial standards.  Institutions can choose to subscribe to a variety of subject-specific collections, so administrators can tailor the accessible content of the portal to user needs. Wanfang Data is a valuable central portal for searching Chinese prior art, although any professional patent searcher will utilize a variety of other free and subscription resources to locate all available Chinese and non-Chinese prior art.
