The State Intellectual Property Office of China (SIPO) has already offered a "patent search" database on its English website for a number of years. This database allows users to search in bibliographic data and titles for Chinese patents and utility models from 1985 onwards via an English interface. For patents, the source also includes English abstracts. Furthermore, a machine translation function is available. Document retrieval is not possible via this source, but provided in other search facilities hosted by SIPO.
Recently, SIPO has added information about the last updates of the data in this source, including the coverage of machine translations, to the website. The new update information is displayed right on top of the English search mask.
