The date, worked out from the register itself.
A US filing gets 30 days from the day it is published in the Trademark Official Gazette, and a first 30-day extension that costs nothing and is granted as of right. We compute each closing day from the publication date in the record and put it at the top of the email.

Nobody posts the start date to you
The 30 days run from publication in the Trademark Official Gazette — a weekly list that nobody outside the profession reads. Mark owners usually meet a conflicting filing much later: a listing comes down, or a letter arrives. By then the clock has been running for weeks, and the cheapest move on the table has expired.
How it works
How the deadline clock works
- 1
The register records a publication date
Our daily pass stores it against the filing, exactly as the office published it.
- 2
The rule for that office is applied
US: 30 days from publication, plus the extensions the office allows. EU: three months from publication, once that ingest is live.
- 3
The date leads everything
The email, the report, the PDF and your calendar feed all show the same closing day and the same number of days left.
Why it matters
What you get
Days left, not “recently”
A countdown computed from the record, re-checked every day, never from the day we happened to notice.
In your own calendar
A private ICS feed puts every closing day in Apple Calendar, Google Calendar or Outlook.
Extensions accounted for
Where an office allows more time, the record shows the extended date as well as the original one.
FAQ
Questions, answered
Where does the 30 days come from?
The USPTO: “any party who believes it may be damaged by the registration … has 30 days from the publication date to file either an opposition to registration or a request to extend the time to oppose”. The Official Gazette is published each Tuesday.
What if the window has already closed?
We still show the filing and say the window is closed, because it is still something you may want to know about and discuss with an attorney. We do not pretend a date is open when it is not.
Is the EU deadline different?
Yes — three months from publication in the EU Trade Marks Bulletin, and it cannot be extended. The rule is implemented; the EU ingest that feeds it is waiting on office access.
