A patent grants an inventor exclusive rights over their product, process, or invention for a period of 20 years. Upon expiry, anyone can request to obtain the patent. A patent holder can renew the patent by paying a surcharge to the maintenance fees. Additionally, expired patents can be sold, and the new buyer can renew the patent by paying the required fees.

The lifetime of a utility patent is 20 years, with the maintenance charges being paid periodically to keep it alive. For patents that have expired, the USPTO maintains an inactive patents database.
