Twenty registers, with the statute behind each. How long you have to oppose a filing, what the clock runs from, and the provision that says so.
These are the rules our deadline engine computes from, not a summary of them.
See the windows01 / Most offices
The window opens at publication, before registration.
The application is examined, then published, and the clock starts. Count from the filing date and you are early. Count from registration and you are late.

02 / The minority, and the trap
These register the mark first. Then the window opens.
Here the mark goes on the register and only then is it published for opposition. Seeing “registered” does not mean you have missed it. Applying the EU’s rule to one of these does not shift a deadline by a few days; it invents one that never existed.

03 / The questions, answered plainly
It depends on the office: 30 days in the US, two months in the UK, France and Canada, three months at the EUIPO and in China. Always counted from the office’s own start event, never from filing. The tables above carry all twenty windows with the statute behind each.
By filing the office’s notice of opposition inside the window: form TM7 in the UK (TM7A to extend, TM7F for the fast track), through ESTTA at the US TTAB, a notice of opposition at the EUIPO. Grounds and fees differ. The unforgiving part is the same everywhere: the deadline.
An EUIPO stage. Once an opposition is filed, a two-month cooling-off period runs before proceedings turn adversarial, jointly extendable to 24 months, and most EU oppositions settle inside it. The EU page covers it.
Watching the registers for new filings close to your mark, so you learn about them while the window is still open rather than after it shuts. That is what the free clearance check and the free watch on one name do: the same engine that computes these deadlines watches the filings.
04 / What “verified” means
Verified is the day each window and its citation were last read against the office’s own statute: 6 August 2026 for this table, re-checked office by office rather than in one sweep. It is not the date this page was edited. If a window has moved since, the date is how you would know to look.
