How long does trademark protection last?Unlike copyrights and patents, trademark rights can last indefinitely as long as the owner continues to use the mark to identify its goods or services. The term of a federal trademark is 10 years, with 10-year renewal terms. However, the USPTO requires that between the fifth and sixth year after the date of registration, the registrant must file an affidavit stating that the mark is still in use. If no affidavit is filed, the registration is cancelled. The USPTO does not remind the trademark owner of this deadline.
