The Canadian Patent Database contains over 2.2 million patent documents from 1869 to the present. This database is updated regularly with newly granted patents and applications opened to public inspection. Searches are performed against the bibliographic and text data fields only, and a "hit list" of matching patents is returned. Images are not searchable but can be viewed for any particular patent that has been returned in a hit list. The text of the abstracts and claims is not available for patents that were granted prior to August 15, 1978. These patents can only be searched by their patent number, titles, owner, inventor, or classification. Note about completeness of the Date Fields: The issue date is searchable from 1869 to the last updated date. The filing date is not available for patents registered prior to August 15, 1978. The priority date and the national entry date are not available for patents registered prior to October 1, 1989.

Engineering Village is an information discovery platform that includes access to Compendex (Computerized Engineering Index), the most comprehensive bibliographic database of scientific and technical engineering research available, covering all engineering disciplines. It includes millions of bibliographic citations and abstracts from thousands of engineering journals and conference proceedings. When combined with the Engineering Index Backfile (1884-1969), Compendex covers well over 120 years of core engineering literature. Users can also search and locate Knovel e-book, journal and conference proceedings on Engineering Village and link through to Knovel for full-text access.

Espacenet's worldwide database enables you to search for information about published patent applications from over 90 different countries and regions. Espacenet offers free access to more than 70 million patent documents worldwide--most of them patent applications rather than granted patents--from 1836 today. Patent applications normally represent the first publication of a new idea, appearing ahead of journal articles and before new products reach the market. Other information includes: patent family information, telling you if similar patents have been claimed in other countries; legal status information, helping you find out whether and in what countries a patent is in force; references to other kinds of technical literature (non-patent literature); citing documents (other documents that have cited the document you are looking at); and links to the European Patent Register for European and Euro-PCT documents. It is possible to print and download documents.

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.

Each patent search includes the patent summary, claims, drawings, citations, and referenced by notes. Patents are from the U.S. Patent and Trademark Office dating as far back as 1790. There are currently about seven million patents. Applications, international patents, and those approved in the past few months are not included.

Cambia created the Lens to create transparency in the patent system, and to serve the public worldwide as a platform to explore, understand and improve its impact on society. The Lens informatics tools can assist the user to determine the boundaries of intellectual property constraints on deliverable innovations, and usable building blocks for future innovations. The key to the Lens is that Cambia is creating an integrated, worldwide, open-source and open access resource that will allow community-developed analytical tools, patent landscapes and decision support software to be created and shared. The Lens enables cartography of the innovation landscape, allowing navigation from an idea to a product (or service) and back again. This makes producing new value in society quicker and more affordable. In short, our goal is to make the world's innovation system navigable by anyone for anything. The Lens is an extension of work started by Cambia in 1999 to render the global patent system more transparent, called the Patent Lens. The Lens is a greatly expanded and updated version of the Patent Lens with a vastly more data and greater analytical capabilities

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.
