Espacenet: The European Patent Office Database

The European Patent Office's database Espacenet provides detailed searching of millions of patent documents – most of them patent applications rather than granted patents – from around the world. 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 patents that have cited the document you are looking at); and links to the European Patent Register documents and to selected national ​patent registers.

US Patent & Trademark Office Web Patent Databases 

The database includes information about all US patents from the first patent issued in 1790 to the most recent issue week. Patents from 1976 to the present offer the full searchable text. Patents from 1790 to 1975 offer only the patent number, issue date, and current US patent classification in the text display, and can be searched only within those fields. However, this limited text display also includes a hyperlink to obtain full-page images of all pages of the patent.

Note: USPTO has two separate databases, one for US granted patents (PatFT database) and one for US patent applications (AppFT database).
