Please consult our Patent Research Guide.
United States Patent and Trademark Office
United States Patent and Trademark Office Patent Full-Text Database
The USPTO database contains records of all patents published since 1976 and all applications published since March 2001.
Use the Quick Search in the Patent Full-Text Database to look for the keywords associated with the patent you're looking for, and connect them with AND, NOT and OR to be more specific, e.g. (sony AND walkman). The Patent Full-Text Database is big and bulky so if you don't use the language it expects, you won't find what you're looking for. Take a look at their Help page. Try combining different terms if you aren't finding a patent you know exists, or ask a librarian for help in doing so.
