Patent Databases (US Patent and Trademark Office)
Search the Patents databases (full-text with images or just bibliographic with quick information) from 1976 to most recent weekly issue. Returns bibliographic data, abstract, and full text of the patent with drawings or photos. Patents from 1790-1976 are also availble, but are searchable only by patent number and current US classifications. Images require ability to view G4 TIFF format. The site provides information on a free version of such a viewer on their Document Formats and Viewers page (on the Web4Lib mailing list, librarians have recommended the AlternaTIFF viewer for Windows machines) . For patent offices in other countries see their Related Sites page.
