When should I file my Trademark Statement of Use?

You should file your Trademark Statement of Use within the following time periods:

- Within six months of the day the USPTO mails you a "Notice of Allowance." This is a written notice of conditional approval sent after the mark is published. You can find the date that the Notice of Allowance was issued by visiting http://portal.uspto.gov/external/portal/tow and entering your USPTO serial number.

- Within a previously-granted extension period from the USPTO.
