What is a Statement of Use (SOU)?

A Statement of Use (SOU) is a document submitted to the USPTO that demonstrates a trademark's actual use in commerce. When an applicant files for a trademark under an "intent to use" basis, they are indicating that they plan to use the mark but have not yet done so. The SOU must be filed after the applicant begins using the trademark, ensuring that it meets legal requirements by proving that the mark is currently being used in the marketplace for the identified goods or services.

The SOU typically includes details such as the date when the mark was first used in commerce, examples of the mark as used in the marketplace, and a declaration that the mark is in use. This is essential for the trademark to be registered officially, as it provides the USPTO with evidence that the trademark is not merely a placeholder but a functioning brand in commerce.

The other options do not accurately represent the purpose of a Statement of Use. It does not function as a declaration of abandonment, nor does it relate to opposition requests or the process of trademark application, highlighting the importance of understanding its specific role within trademark registration.
