What is Declaration of Use?

A declaration of use is a sworn statement submitted to a trademark office by the owner of a registered mark, affirming that the mark is currently being used in commerce in connection with some or all of the goods or services listed in the registration. In the United States, this requirement is primarily fulfilled through Section 8 affidavits, which must be filed at specific intervals after registration to prevent the registration from being cancelled.

The declaration of use serves a critical housekeeping function in the trademark system. It ensures that the register remains an accurate reflection of marks that are actually in use, rather than a repository of dormant or abandoned brands. By requiring owners to periodically prove use, the system frees up marks that are no longer being used, making them available for new applicants. The declaration must typically be accompanied by a current specimen of use and may include a fee.

If the owner is no longer using the mark for some of the goods or services listed in the registration, the declaration must either delete those items or, in some systems, provide an explanation for non-use (such as special circumstances excusing temporary non-use). Filing a false declaration — claiming use when the mark is not actually being used — constitutes fraud on the trademark office and can result in cancellation of the entire registration.

Why It Matters

The declaration of use is not optional — it is a mandatory maintenance requirement in use-based systems. At the USPTO, failure to file a Section 8 declaration between the fifth and sixth year after registration results in cancellation. A second declaration is required at the time of renewal (between the ninth and tenth year), and then with each subsequent renewal. These deadlines are absolute, with only a limited grace period available for a surcharge.

For companies with large portfolios, the administrative burden of tracking and filing declarations of use is significant. Each declaration requires a current specimen of use, which means the company must verify that it is still using the mark as shown and that the specimen meets the office's requirements. Changes in business practices — such as moving from physical retail to e-commerce — may require updated specimen strategies.

How Signa Helps

Signa's monitoring platform automates the tracking of declaration of use deadlines across global trademark portfolios. By pulling registration dates and maintenance filing records from over 200 offices, Signa calculates upcoming deadlines and alerts portfolio managers well in advance. This automated approach eliminates the risk of missed filings that result in cancellation.

Signa's data tools also help identify marks in a portfolio that may not be in active use, allowing brand owners to make informed decisions about whether to maintain or abandon specific registrations before incurring the cost of filing declarations and specimens.

Real-World Example

A consumer electronics company owns 85 U.S. trademark registrations spanning three decades of product development. Many of the older marks cover product lines that have been discontinued. As the six-year declaration deadline approaches for a batch of registrations, the IP team uses Signa's API to generate a report of all marks with upcoming Section 8 deadlines. Cross-referencing with current product catalogs, the team identifies 12 registrations where the mark is no longer used for any listed goods. Rather than filing false declarations, the team allows those registrations to expire and focuses resources on maintaining the 73 active marks, filing declarations with current specimens that reflect the company's shift to online direct-to-consumer sales.
