United States Patent and Trademark Office (USPTO)


The United States Patent and Trademark Office (USPTO) web site is a good place to learn about patents and the office's mission and activities. Search the full text of patents since Jan 1, 1976. Patents issued from 1790 through 1975 are searchable only by patent number and current U.S. classifications. Page images are available back to 1790.


The USPTO now offers web access to selected information from its internal trademark database, particularly the trademark data currently available on two of PTO's Cassis CD-Rom products: Trademarks Registered and Trademarks Pending. The text will be updated on a two-month cycle. Images will be added as they become available.
