Introduction

The State Intellectual Property Office (SIPO) of the PRC (People's Republic of China) offers a free English patent search interface for invention and utility models.

The search will be conducted on English-language titles and abstracts in the collection. Users can also produce a full text machine translation of individual documents. The machine translation technology, called the China Patent Machine Translation system (CPMT), was researched and developed by China Patent Information Center.[1]


Use

Users can access the patent search system through the SIPO English-language homepage by selecting the "Patent Search" link in the menu bar on the right side of the page. Users can select to search within the Invention or Utility Model databases (or within both). Users can enter queries within multiple fields by utilizing the top half of the site to search by Publication Number, Publication Date, Application Number, Application Date, Title, Abstract, IPC, Applicant, Inventor, Patent Agent, Patent Agency Code, Priority, and Province/Country Code. Users can also enter queries in the Combination Search at the bottom of the page, where they can search within multiple fields, use parentheses, and join search terms by Boolean operators. A guide for correctly formatting search terms and allowable operators is found under "Help."

Users can choose to sort their results by any field listed in the "Sort By" drop-down menu at the top of the search page, in ascending or descending order.

When users select a result from the record list to view, they will first be taken to a bibliographic record of the patent document. Users can view a machine translation of the full document by selecting "Machine Translation" at the bottom of the page. Upon first selecting the "Machine Translation" button for a particular record, an English-language translation of the claims will be displayed. To see the rest of the specification, users should scroll to the bottom of the page and select the "Description" button.
