Patent numbers are used to access valuable information on items such as the inventor's name, patent issue date and the purpose and use of the original item. Finding information on a specific invention is simple if you have the item's patent number. The United States Patent and Trademark Office maintains a searchable database of information regarding patents.

Visit the United States Patent and Trademark Office (USPTO) website and enter the patent number into the search engine.

Review the search result for that specific patent number, which includes the inventor's name, patent issue date, application number, filing date, United States and international class, and claims and descriptions of the patented item. Print the document for your records.

Click on the "Images" button at the top of the page to view images of the front page of the patent documents, drawings, specifications and claims related to that patent number. Print the images for your records.

Click on the "Add to Cart" button to order a certified or uncertified copy of the patent documents from the USPTO.

Click "Checkout" to finalize your order. Create a new account if you don't have one or login using your login and password to complete your purchase.

Check the Official Gazette for Patents online to review the new patented inventions for that week. Access to the Official Gazette is free online and the Gazette is published every Tuesday.
