Excusable nonuse of a trademark occurs when circumstances beyond the control of a trademark owner causes a temporary interruption in the use of the mark. The concept of excusable nonuse most frequently arises when it comes time for the owner of a U.S. trademark registration to file the Section 8 Declaration of Use or the Section 71 Declaration of Use with the United States Patent and Trademark Office (USPTO). Normally, both of these declarations require verification that the registered trademark is in use in commerce in order to prevent the registration from being canceled.
