The USPTO requires specific documents to be filed at recurring intervals. Mark your calendar carefully for these crucial deadlines:
1. Initial Renewal: Between the 5th and 6th Year After Registration
This is your first critical filing. You must submit two declarations electronically through the USPTO's Trademark Electronic Application System (TEAS):
Declaration of Continued Use (Section 8 Affidavit): You must affirm that your trademark is still actively in use in commerce for the goods/services listed in your registration. You will need to provide a specimen (proof of use) for each class of goods/services. The official USPTO guide provides detailed requirements for specimens.
Declaration of Incontestability (Section 15 Declaration - Optional but Recommended): If your mark has been in continuous use for five consecutive years after its registration date, you can file this. It makes your trademark "incontestable," significantly strengthening your rights and limiting challenges to your registration.
Filing Window: The one-year period between the 5th and 6th anniversaries of your registration date. A six-month grace period follows, but with an additional fee.
2. Subsequent Renewals: Between the 9th and 10th Year, and Every 10 Years Thereafter
Starting from your 10th anniversary, and every 10 years thereafter, you will need to file two documents:
Declaration of Continued Use (Section 8 Affidavit): Same requirements as the initial filing – affirm continued use and provide specimens for each class.
Application for Renewal (Section 9 Renewal): This formally renews your registration for another 10-year term.
Filing Window: The one-year period preceding the end of every 10-year term. A six-month grace period follows, with an additional fee. The official USPTO guide on these requirements is a must-read.
