    Section 8 and Section 15 Declarations: Maintaining Your Trademark

    Section 8 and Section 15 Declarations: Maintaining Your Trademark

    Your trademark registration is not permanent. Without timely maintenance filings, the USPTO will cancel your registration — and unlike many other legal deadlines, there is no way to revive a cancelled trademark registration for failure to file a Section 8 declaration. Understanding these critical maintenance requirements is essential for every trademark owner.

    Why Maintenance Filings Matter

    Many trademark owners assume that once they receive their registration certificate, they're protected indefinitely. This is a dangerous misconception.

    The USPTO requires affirmative proof of continued use at regular intervals. If you fail to file the required declarations within the filing windows, your registration will be cancelled — regardless of how much you've invested in building your brand.

    Pro Tip: The USPTO does not send reminders before maintenance deadlines. Set calendar reminders for all your maintenance filing windows, or use a trademark monitoring service that tracks deadlines automatically.

    Section 8: Declaration of Continued Use

    A Section 8 Declaration (formally "Declaration of Use or Excusable Nonuse Under Section 8") proves to the USPTO that you are still using your trademark in commerce.

    Filing Window and Deadline

    Detail Information
    First filing window Between the 5th and 6th year after registration
    Subsequent filings Combined with Section 9 renewal every 10 years
    Grace period 6 months after the filing window closes
    Grace period surcharge $100 per class
    Fee per class $325 per class
    Consequence of missing Cancellation — no petition to revive

    *Citation: 15 U.S.C. § 1058 — Duration, Affidavits and Fees*

    What You Must Submit

    1. A specimen showing current use — Same requirements as original specimens. See our Specimen Guide
    2. A verified statement (declaration) — Signed under penalty of perjury that the mark is in use in commerce
    3. The filing fee — $325 per class

    Partial Use

    If you're no longer using the mark on some of the goods/services in your registration, you must delete those goods/services from the registration. You cannot maintain registration for goods/services you're not using.

    Section 15: Declaration of Incontestability

    A Section 15 Declaration grants your trademark incontestable status — one of the most valuable legal protections available to trademark owners.

    What Incontestability Means

    An incontestable trademark registration cannot be challenged on most grounds, including:

    • Mere descriptiveness (Section 2(e)(1))
    • Geographic descriptiveness
    • Primarily a surname

    This dramatically strengthens your position in court and against challengers.

    Requirements

    Requirement Detail
    Continuous use Mark must have been in continuous use for 5 consecutive years after registration
    No pending proceedings No final decision adverse to the owner's claim of ownership
    No successful challenge No pending or successful challenge to the mark
    Filing fee $250 per class
    Filing window Any time after 5 years of continuous use

    *Citation: 15 U.S.C. § 1065 — Incontestability*

    Benefits of Incontestability

    Protection Without Incontestability With Incontestability
    Descriptiveness challenge Vulnerable Immune
    Surname challenge Vulnerable Immune
    Geographic descriptiveness Vulnerable Immune
    Presumption of validity Basic Conclusive
    Court enforcement Must prove validity Validity presumed
    Cancellation grounds Many available Limited to specific grounds

    Grounds That Can Still Challenge an Incontestable Mark

    Even incontestable marks can be challenged on these limited grounds:

    • Fraud in obtaining registration
    • Abandonment through non-use
    • Genericness — the mark has become the common name for the product
    • Functionality — the mark is functional rather than distinctive
    • Antitrust violation — mark used to violate antitrust law

    Combined Filing Strategy

    The most efficient approach is to file Section 8 and Section 15 together during the years 5–6 window, then file combined Section 8 and Section 9 renewals every 10 years.

    Trademark Maintenance Timeline

    Year Filing Required Fees (per class)
    Years 5–6 Section 8 + Section 15 $325 + $250 = $575
    Years 9–10 Section 8 + Section 9 (renewal) $325 + $325 = $650
    Years 19–20 Section 8 + Section 9 (renewal) $325 + $325 = $650
    Every 10 years after Section 8 + Section 9 (renewal) $325 + $325 = $650
    Pro Tip: Filing Section 15 costs only $250 per class and provides enormous legal benefits. There is no reason not to file it if you qualify. Always file Section 15 combined with your first Section 8 declaration.

    What Happens If You Miss the Deadline

    Section 8: Cancellation

    If you miss the Section 8 filing window (including the 6-month grace period), your trademark registration will be cancelled. Unlike many other USPTO deadlines, there is no petition to revive for a missed Section 8 filing. The registration is permanently lost.

    To protect the same mark again, you would need to file an entirely new application and go through the full examination process.

    Section 15: Lost Opportunity

    Missing the Section 15 filing window is less catastrophic — your registration survives, but you lose the opportunity to claim incontestability. You can still file Section 15 later, but only once you've accumulated another 5 years of continuous use.
