Searchable databases of some of the world's major patent and trademark offices. Tulane Libraries do not collect print copies of patents, but the full-text of many patents are freely available electronically.

United States Patent Public Search
Provides free access to U.S. patents full-text since 1976 and full-page images since 1790.

Patents from 1790 to December 1975 offer only the patent number and the current US patent classification in the text display, and can be searched only by those fields. However, this limited text display also includes a hyperlink to obtain full-page images of each page of the patent.
