TCP Law's Trademark Maintenance Calculator is a free online tool that helps trademark owners calculate the key filing deadlines required to keep a federal trademark registration active with the USPTO. By entering your registration number and registration date, the calculator generates the earliest and latest filing windows for each required maintenance document — including the 5th–6th year Section 8 Declaration, the 9th–10th year combined Section 8 and Section 9 Renewal, and every combined Section 8 and Section 9 filing due every ten years thereafter. Missing these deadlines results in cancellation of your trademark registration, making this calculator a practical first step in understanding your maintenance obligations. TCP Law can be contacted directly to help manage your trademark maintenance filings.

Maintaining a federal trademark registration requires two types of periodic filings with the USPTO. The first is a Declaration of Use under Section 8, which must be filed between the 5th and 6th year after registration — this filing confirms that the mark is still actively in use in commerce for the listed goods or services, or provides a valid reason for any nonuse. Thereafter, a combined Section 8 Declaration of Use and Section 9 Renewal Application must be filed every ten years, with the first such combined filing due between the 9th and 10th year after registration. Each filing must include proof that the mark is still in use in commerce for the identified goods and services, or a valid excusable nonuse explanation. Failure to file on time results in cancellation of the registration — there is no cure once the deadline has passed without filing.

Missing a required trademark maintenance filing deadline results in the cancellation of your USPTO trademark registration — a consequence that cannot be undone after the fact. Once a registration is cancelled for failure to maintain, the nationwide rights, legal presumptions of ownership, and enforcement advantages that federal registration provides are lost. To restore protection, you would need to file a new trademark application and go through the entire examination process again — with no guarantee of success if conflicting marks have been registered in the interim. The Trademark Maintenance Calculator on TCP Law's website helps trademark owners identify their filing windows in advance so deadlines can be calendared and met. TCP Law also assists clients in managing their trademark maintenance obligations directly.

The Trademark Maintenance Calculator accounts for both the standard filing window and an extended filing window — the latter available with an additional fee. For each maintenance filing, there is an earliest filing date and a latest filing date within the standard window, as well as a later deadline available with a surcharge for a six-month extension. Filing within the grace period with the associated fee keeps the registration active. However, once the grace period has also passed without a filing, the registration is cancelled with no further opportunity to cure. This makes proactive deadline management — rather than reactive emergency filing — the strongly preferred approach. TCP Law can assist with monitoring and managing these deadlines as part of an ongoing trademark maintenance engagement.

A Section 8 Declaration of Use requires the trademark owner to affirmatively declare that the mark is still in use in commerce in connection with the goods and services identified in the registration, and to submit a specimen — a real-world example showing the mark actively being used in the marketplace — as proof of that continued use. If the mark is not currently in use for some or all of the identified goods and services, the owner must provide a valid reason for nonuse — known as excusable nonuse — to avoid cancellation of those goods and services from the registration. The Section 8 filing is not merely a renewal form; it is a declaration under penalty of cancellation that the mark continues to function as an active trademark in commerce. Ensuring the specimen and declaration accurately reflect the current state of use is an area where having an IP attorney assist adds real value.

After the initial 5th–6th year Section 8 filing and the first combined 9th–10th year Section 8 and Section 9 filing, the combined Section 8 Declaration and Section 9 Renewal Application must be filed every ten years thereafter for as long as the trademark owner wishes to maintain the registration. This means that a trademark registration can remain active indefinitely — there is no fixed expiration date — as long as the mark continues to be used in commerce and the required maintenance filings are submitted on time within each ten-year renewal window. TCP Law's Trademark Maintenance Calculator generates the filing windows for all three maintenance periods, and TCP Law can assist with managing these ongoing filing obligations.

No — the calculator is explicitly a tool for informational purposes only and does not constitute legal advice or create an attorney-client relationship. The calculated filing windows are based on the registration date entered and are intended as a reference guide, not a legally binding determination of your specific maintenance obligations. Individual circumstances — such as amendments to the registration, changes in use, or special filing considerations — may affect your actual obligations in ways the tool cannot account for. Users are advised not to rely on the results to make legally binding decisions, and to consult a qualified attorney for specific legal advice. TCP Law offers direct assistance with trademark maintenance management for owners who want professional oversight of their filing deadlines and obligations.

The Trademark Maintenance Calculator allows you to enter one registration at a time by registration number and date, generating the maintenance filing schedule for that specific registration. For trademark owners managing multiple registrations — which is common for businesses with portfolios of brand names, logos, and product marks across multiple classes — keeping track of staggered maintenance deadlines across different registration dates can become complex. While the calculator is a useful tool for checking individual registrations, managing a portfolio of registrations with accuracy and confidence typically calls for professional trademark docketing services. TCP Law assists clients with trademark portfolio management and maintenance filing, ensuring deadlines are tracked and met across all active registrations.

The Section 9 Renewal Application is the filing that formally renews a trademark registration for another ten-year term — without it, the registration expires at the end of each ten-year period regardless of continued use. The Section 8 Declaration of Use, by contrast, is a separate requirement that confirms the mark is still actively in use in commerce. While these are two legally distinct requirements, after the first registration period they are filed together as a combined Section 8 and Section 9 filing every ten years. Both must be submitted and accepted by the USPTO for the registration to remain active — a Section 9 renewal without a valid Section 8 declaration, or a Section 8 declaration without a Section 9 renewal, does not fully satisfy the maintenance requirements.

Yes — this is a critical misconception that leads to trademark registrations being cancelled unnecessarily. A federal trademark registration is not self-maintaining: it requires affirmative action by the owner at specific intervals to remain active. The 5th–6th year Section 8 filing and the ongoing Section 8 and Section 9 combined filings every ten years are not optional or automatic — they must be actively prepared, filed, and accepted by the USPTO, with proof of use submitted each time. A trademark owner who neglects these deadlines — even one who is actively using the mark in commerce and has no intention of abandoning it — will have their registration cancelled for failure to maintain. TCP Law's free Trademark Maintenance Calculator and direct trademark maintenance services are both available to help owners stay on top of these obligations.
