As a result of cooperative effort between the United States Patent and Trademark Office (USPTO) and State Intellectual Property Office (SIPO) of the People's Republic of China, Chinese patent documentation is now available for search and retrieval from the USPTO website via the Global Patent Search Network. This tool will enable the user to search Chinese patent documents in the English or Chinese language. The data available include fulltext Chinese patents and machine translations. Also available are full document images of Chinese patents which are considered the authoritative Chinese patent document. Users can search documents including published applications, granted patents and utility models from 1985 to 2012. This collection will be periodically updated to include additional years of coverage.
This page is the starting point for the USPTO's free patent databases covering patent grants (full-text since 1976, full-page images since 1790), and patent applications (published since 15 March 2001). Patents issued between 1790 and 1976 are searchable only by patent number and current U.S. classification. Patents issued after 1976 may be searched by any keyword.
PatentsView is a patent data visualization and analysis platform intended to increase the value, utility, and transparency of US patent data. The initiative is supported by the Office of Chief Economist in the US Patent & Trademark Office (USPTO) PatentsView is intended to encourage the study and understanding of the intellectual property (IP) and innovation system; to serve as a fundamental function of the government in creating "public good" platforms in these data; and to eliminate redundant cleaning, converting and matching of these data by individual researchers, thus freeing up researcher time to do what they do best--study IP, innovation, and technological change. Access patent information via API, bulk download, or data query. The data are derived from USPTO bulk data files. These data are provided for research purposes and do not constitute the official USPTO record.
