On 11 March 2012, SIPO's "Intellectual Property Publishing House" (IPPH) launched a new Chinese interface of the CNIPR database. The old version, which had been used in parallel with a trial version for several months, is no longer online. After the relaunch of the search interface, the features of this source have remained largely the same. Retrieval of documents, citations, information on family members and legal status information etc. are still available free of charge. More advanced functions are available by taking out a subscription
The EPO has adapted its existing step-by-step search guides to the new interface of this source. You can find these in the "China - Searching in databases" section of the "virtual helpdesk" on Asian patent information.
