Amendment to Allege Use Preparation

An Amendment to Allege Use (AAU) is a formal document filed with the USPTO in a trademark application filed on an intent-to-use (ITU) basis. It informs the USPTO that you have started using your trademark in commerce before the registration is finalized

You can file an Amendment to Allege Use (AAU) once you’ve started using your trademark in commerce but before the USPTO issues a Notice of Allowance. It lets the USPTO know your mark is in use, moving your application toward registration.

An Amendment to Allege Use (AAU) is filed before the USPTO issues a Notice of Allowance to show your mark is already in use whereas A Statement of Use (SOU) is filed after the Notice of Allowance for the same purpose—proving actual use and moving the application toward registration.

After filing a Statement of Use (SOU), the USPTO reviews it to ensure the mark is in actual use and the specimens are acceptable. If approved, the mark moves toward registration; if not, an Office Action may request corrections or additional evidence

Yes, you can amend a trademark application to correct errors, clarify goods/services, or reflect actual use. Minor changes are allowed, but major alterations that create a new mark or expand goods/services usually require filing a new application.
