TCP Law's free Trademark Maintenance Calculator calculates the key USPTO filing deadlines required to keep a federal trademark registration active. Enter your registration number and date to generate filing windows for your Section 8 Declaration, Section 9 Renewal, and all subsequent combined filings. Missing these deadlines results in cancellation. Contact TCP Law to manage your trademark maintenance filings professionally.

Two types of periodic filings are required. A Section 8 Declaration of Use must be filed between the 5th and 6th year after registration, confirming the mark is still in active commercial use. A combined Section 8 and Section 9 Renewal must then be filed every 10 years. Each filing requires proof of current use or a valid excusable nonuse explanation. Use the free Trademark Maintenance Calculator to track your deadlines.

Missing a required maintenance deadline results in cancellation of your USPTO trademark registration — a consequence that cannot be undone. Nationwide rights, legal presumptions of ownership, and enforcement advantages are lost. To restore protection, you would need to file a new application with no guarantee of success. Use the Trademark Maintenance Calculator to identify your deadlines in advance, and contact TCP Law to manage filings professionally.

Yes — the Trademark Maintenance Calculator shows both the standard filing window and an extended window available with an additional surcharge. Filing within the grace period with the associated fee keeps the registration active. Once the grace period also passes without filing, the registration is cancelled with no further opportunity to cure. Proactive deadline management is strongly preferred over reactive emergency filing. Contact TCP Law to stay ahead of your trademark maintenance obligations.

A Section 8 Declaration requires the trademark owner to confirm the mark is still in active commercial use and submit a specimen — a real-world example showing the mark being used in the marketplace. If the mark is not currently in use, a valid excusable nonuse explanation must be provided. Ensuring the specimen and declaration accurately reflect current use is an area where having TCP Law assist adds real value. Read about trademark renewal requirements and deadlines.

After the initial 5th–6th year Section 8 filing and the first combined 9th–10th year Section 8 and Section 9 filing, a combined renewal must be filed every ten years thereafter — indefinitely, as long as the mark remains in active use. A trademark registration can last forever with proper maintenance. The Trademark Maintenance Calculator generates all three maintenance windows automatically. Contact TCP Law to manage ongoing renewals professionally.

No — the calculator is explicitly for informational purposes only and does not constitute legal advice or create an attorney-client relationship. Calculated filing windows are based on the registration date entered and may not account for individual circumstances such as registration amendments or changes in use. Users are advised not to rely on results to make legally binding decisions. Contact TCP Law for professional trademark maintenance management, or book a free consultation to discuss your specific registration.

The Section 8 Declaration confirms the mark is still in active commercial use — without it, the registration is cancelled regardless of continued use. The Section 9 Renewal formally renews the registration for another ten-year term — without it, the registration expires. After the first registration period, both are filed together as a combined Section 8 and Section 9 every ten years. Both must be accepted by the USPTO for the trademark registration to remain fully active.

The calculator processes one registration at a time by number and date. For trademark owners managing multiple registrations across different classes and filing dates, staggered deadlines can become complex to track manually. While the Trademark Maintenance Calculator is a useful individual check, managing a portfolio professionally calls for dedicated docketing services. Contact TCP Law to discuss trademark portfolio management and maintenance filing across all active registrations.

Yes — this is a critical misconception. A federal trademark registration requires affirmative maintenance filings at specific intervals to remain active. Missing the 5th–6th year Section 8 deadline or any subsequent combined filing results in cancellation — even if you are actively using the mark. Use TCP Law's free Trademark Maintenance Calculator to identify your deadlines, and read about trademark renewal requirements to understand your ongoing obligations.
