The Intellectual Property Publishing House (IPPH) of SIPO has launched a new version of its Chinese CNIPR platform for searching patents, utility models and designs. The interface has been restructured, but the features which can be used free of charge remain largely the same as before. For registered or subscribed users, more advanced search and retrieval options have become available. An update of the corresponding English language interface of the CNIPR platform is currently under way (subscription required). Further information may be requested from firstname.lastname@example.org.
Revised step-by-step guides for using the new CNIPR search platform in Chinese language can be found in the "China - Searching in databases" section of the EPO's virtual helpdesk on Asian patent information.
