U.S. Patent Searches

U. S. Patent and Trademark Office features online publications, downloadable forms in Adobe Acrobat format, and other information. Use the U.S. Patent Databases to obtain the "full text of all US patents issued since January 1, 1976, and full-page images of each page of every US patent issued since 1790." Although the site includes older patents, search options are limited to patent number and current US classification number. Use the Manual of U. S. Patent Classification to determine the current US classification number.


Google Patent Search allows the user to search the entire contents of U.S. patents filed from 1776 to the present. Use the advanced search feature to search by inventor name, patent number, issue or filing date, keyword, phrase, and current U.S. or international patent classification. Although its ability to search by patent classification is limited, it exposes the complete contents of U.S. patents to searching.
