In many countries, yes. A Declaration of Use (or a similar use confirmation filing) is a key trademark maintenance requirement to keep your registration valid and enforceable.
For example, this type of filing is commonly required in jurisdictions such as the United States, Mexico, Argentina, the Philippines, Cambodia, and Haiti. Similar rules may apply in other countries depending on how and when your trademark was registered.
If you miss the deadline, your trademark may become vulnerable, lapse, or create complications at renewal time. Since requirements vary by country, we’ll confirm whether it applies to your trademark and when it’s due based on your registration details.
