Trademark deadline calculator
Two date calculators for US trademark work: the opposition window after publication, and the statement of use deadline after a notice of allowance. The math runs in your browser; nothing is sent anywhere.
Opposition window
After a mark is published for opposition in the Official Gazette, the clock starts at 30 days.
Statement of use
After a notice of allowance, an intent-to-use application must show use in commerce.
How the rules work
An opposition is due within 30 days of publication (37 CFR 2.101). Extensions are capped at 180 days from publication and can be requested at most three times (37 CFR 2.102): a first 30-day extension on request, a further 60 days for good cause, and one final 60 days with the applicant's consent or extraordinary circumstances.
A statement of use is due within six months of the notice of allowance, extendable in six-month increments up to 36 months total. Extensions must be filed before the current deadline and carry a fee per class.
Questions
Is this legal advice?
No. It does the date arithmetic for two common US trademark deadlines and cites the rules it uses. Verify deadlines at uspto.gov, and have counsel handle filings.
Why did my deadline move to the next business day?
Under 37 CFR 2.196, a filing deadline that falls on a Saturday, Sunday, or federal holiday extends to the next business day. This tool applies that rule automatically.
Can an opposition window really reach 180 days?
Yes. A first 30-day extension is granted on request; a further 60 days is available for good cause; one final 60 days requires the applicant's consent or extraordinary circumstances. The total cannot exceed 180 days from publication. See 37 CFR 2.102.
