Generally speaking, a utility patent will last 20 years from its filing date. In contrast, a design patent lasts 15 years from the day it is granted. There are also several factors that can affect the term of a patent, i.e., when a patent will expire. These factors include, but are not limited to, whether the patent is a continuation application, whether a terminal disclaimer was filed, whether any patent term extension was granted by the U.S. Patent and Trademark Office, and whether the patent owner has paid the necessary maintenance or annuity fees.

You should consult an experienced patent attorney to determine when a patent will expire. Feel free to contact Smith & Hopen for additional information.
