SOU Extension Made Simple

An SOU Extension request allows applicants additional time from the USPTO when a trademark is not yet ready for use, helping protect priority while preparing products, services, marketing, and lawful commercial launch for businesses nationwide.

  • Extension filing accuracy
  • Compliance with USPTO
  • Reduced abandonment risk

What is a SOU Extension?

A Statement of Use Extension, often called an SOU Extension, is a formal request submitted to the USPTO by an applicant seeking additional time before proving trademark use publicly and commercially for business purposes. This request must be filed within six (06) months following the Notice of Allowance and is required when an ‘Intent of Use’ application needs more preparation time before registration continues without risking application abandonment or loss.

More often than not, an SOU Extension must be filed alongside the following items:

  • Applicable fee
  • Request detailing continued use of trademark
  • Signed declaration by the applicant

What if More Time is Needed?

If your trademark is not yet in commercial use by the required USPTO deadline, filing a Statement of Use Extension becomes necessary. Without an approved extension, your application may be abandoned, forcing you to restart the filing process and lose your original priority date entirely. Missing this deadline can result in avoidable delays, added costs, and setbacks before your brand is legally protected and registered.

Filing extensions on time allows applicants to move forward strategically while finalizing products, services, packaging, or marketing materials without pressure or loss of trademark rights. Proper extension handling significantly reduces registration risks and keeps your application active.
