The Intellectual Property Publishing House (IPPH) of SIPO has launched a new version of its Chinese CNIPR website. This website is the main entry page to the CNIPR search platform which offers a variety of information free of charge, including Chinese legal status information and citations. A subscription is required for using more advanced features and for searching in English language. The search interface of the database currently remains the same as before.
Step-by-step guides for using the CNIPR search platform in Chinese language can be found in the "Searching in databases" section of the EPO's virtual helpdesk on Asian patent information.
