The United States Patent and Trademark Office (USPTO) is a fee-funded agency of the U.S. Department of Commerce. The role of the USPTO is to grant patents for the protection of inventions and to register trademarks and service marks for products and services, respectively.

To determine if a patent is still in force, you will need access to the USPTO's website. You can find most of the information in the text-based display, but not all. You will need to look at the patent image, which is in PDF format.
