Trademark practice is built on deadlines. Miss an office action response and the application is abandoned. Miss a Section 8 declaration and the registration is cancelled. Miss a Statement of Use extension and a year of prosecution work is lost. Every stage of the trademark lifecycle carries its own set of deadlines, and every deadline carries consequences that range from expensive to irreversible.
This guide organizes every major trademark deadline by lifecycle stage, from filing through decades of post-registration maintenance. Each section links to a detailed article covering that topic in depth. For a visual overview of the entire process, see The Trademark Application Timeline: Filing to Maintenance. Whether you are building a docketing system for your practice, training a new associate, or simply looking for a single reference that covers everything, this is the starting point.

Key USPTO Trademark Deadlines Attorneys Must Track
Before diving into the lifecycle, start with the deadlines that generate the most malpractice exposure and the most client harm when missed.
- 5 Trademark Deadlines Every Solo Attorney Must Track — The five deadlines that carry the most risk for solo attorneys and how to stay on top of them.
- USPTO Trademark Deadline Cheat Sheet — Every USPTO trademark deadline in one reference. Office actions, SOUs, maintenance filings, and grace periods.
- Trademark Deadlines and Attorney Malpractice — What the cases say about missed trademark deadlines and how courts evaluate attorney liability.
Stage 1: Examination and Office Actions
After a trademark application is filed, the USPTO assigns an examining attorney who reviews the application for compliance with the Lanham Act. If the examiner finds issues, an office action is issued. The response deadline is 3 months from the issue date, extendable to 6 months with a $125 per class fee. Failure to respond results in abandonment of the application.

- Specimen Rejections: What Triggers Them and How to Respond — The most common specimen problems, how to fix them, and how to avoid them in the first place.
Stage 2: Publication and Opposition
If the application passes examination, it is published in the Official Gazette for a 30-day opposition period. Any party who believes they would be damaged by the registration may file an opposition or request extensions of time to oppose, up to a total of 180 days from publication.

- TTAB Cancellation Proceedings — Answer deadlines, discovery periods, trial dates, and appeal windows in cancellation actions.
Stage 3: Notice of Allowance and Statement of Use
For intent-to-use applications (Section 1(b)), a Notice of Allowance issues after the opposition period closes without an opposition. The applicant then has 6 months to file a Statement of Use, with up to five additional 6-month extensions available, allowing a maximum of 36 months from the NOA date.

- SOU Extensions: How Many Can You File? — The complete guide to Statement of Use extension chains, costs, and deadlines.
Stage 4: Post-Registration Maintenance
Registration is not the finish line. It is the beginning of a maintenance schedule that extends for the life of the mark. Section 8 declarations of continued use are due between years 5 and 6. Combined Section 8 and 9 renewal filings are due between years 9 and 10, and every 10 years after that. Miss one, and the registration is cancelled with very limited options for correction.

- Building a Trademark Renewal Reminder System — The three-layer approach to renewal tracking: calculation, notification, and verification.
Stage 5: International Deadlines (Madrid Protocol)
Marks that reach the United States through the Madrid Protocol follow different maintenance rules. Section 71 declarations replace Section 8 declarations. Renewal is handled through WIPO on a separate timeline. The five-year dependency period ties the international registration to the underlying home-country registration. If the home registration is cancelled or restricted during that period, the international registration can collapse correspondingly.
- Madrid Protocol Trademark Deadlines — International registration deadlines that differ from domestic practice, including the dependency period and dual-track maintenance.
- Section 71 Affidavits: The Madrid Maintenance Deadline — How Section 71 differs from Section 8, when the deadlines fall, and why this is one of the most commonly missed obligations.
