Apart from renewals, the USPTO requires additional maintenance filings to keep a trademark active and enforceable.
Declaration of Use (Section 8) – Between the 5th and 6th Year
Trademark owners must file a Declaration of Use to confirm that the mark is still in commercial use. This prevents businesses from holding trademarks without actively using them. If a trademark is not in use, the owner may file an excusable non-use declaration, but strong justification is required.
Declaration of Incontestability (Section 15) – Optional but Recommended
If a trademark has been in continuous use for five (5) years, owners may file a Declaration of Incontestability (Section 15) alongside the Section 8 filing. This grants the trademark stronger legal protection and makes it harder for third parties to challenge its validity.
Trademark Renewal (Section 9) – Every 10 Years
The Renewal Application (Section 9) must be filed alongside a new Declaration of Use (Section 8) every 10 years. If the owner fails to meet this requirement, the trademark will be canceled.
