How Long Does A United States Trademark Last?
A United States trademark lasts for a period of 10 years from the date of registration, provided that the trademark is used in commerce and the required maintenance documents are filed with the United States Patent and Trademark Office (USPTO).
In order to maintain a trademark registration, the owner of the trademark must file a declaration of use and a specimen of use showing that the trademark is still in use in commerce between the fifth and sixth year following registration, and again between the ninth and tenth year following registration. If the required maintenance documents are not filed, the trademark registration may be canceled.
After the initial 10-year period, the trademark registration can be renewed for additional 10-year periods as long as the trademark is still in use in commerce and the required renewal documents are filed with the USPTO.
It is a good idea to consult with a trademark attorney or other professional to assist with the maintenance and renewal of your trademark registration and to ensure that your trademark remains in good standing.
