Type the registration date and the date you plan to file. It returns the maintenance window, the day the registration is cancelled, and the fee per class from the USPTO schedule revised 2026
An IP attorney charges $300-$500 per class for a maintenance filing; the USPTO's own grace fee adds $100 per class on top (USPTO fee schedule effective 2025-01-19, revised 2026-08-14).
Buy the full version — $60You type seven things: the registration date from the certificate, the date you plan to file, the number of classes, whether the basis is US or Madrid, Section 15 on or off, paper or electronic, and your professional quote per class. It returns nine values, including the statutory deadline, the day the USPTO cancels the registration, and the exact fee.
US small-business and brand owners who filed their own trademark and now hold the registration, and IP paralegals who keep a renewal docket. Anyone who has to answer the question "is this mark still alive and what does it cost to keep it" without opening a billing file.
The fees changed on 2025-01-18: Section 8 went from $225 to $325 per class. Language models trained before that still quote $225, and the USPTO page gives the fee table but does no date arithmetic. This counts the anniversaries from your registration date and applies the grace fee.
Every calculation is free with no key and no limit: all nine outputs from all seven inputs, any number of classes, any number of registrations, in the extension popup and on the web page. The $60 licence adds two things on a different axis: a .csv export of the worked result, and browser reminders 30, 14 and 1 day before your date.
An IP attorney charges $300-$500 per class for a maintenance filing on top of the USPTO fee. Missing the statutory deadline adds the USPTO grace fee of $100 per class per component, and missing the grace date cancels the registration, which means refiling from scratch.
