How long do you have to oppose a German trademark?
Three months from registration.

Registration is the start, not the end.

Germany is one of the minority of offices that registers a mark first and runs opposition afterwards. Seeing "registered" on the register does not mean you have missed it — for a recently registered mark it usually means the clock has just started.

Not every office works this way.

Germany runs opposition after registration. Most offices do the opposite — the EU, the UK, the US, Canada and others open the window at publication of the application. The other post-registration offices we cover are Switzerland, Japan, Sweden.

Applying one office’s rule to another does not shift a deadline by a few days. It invents one that never existed — and the real one may already have closed.

It is not over, but the route changed.

Once opposition lapses you are into cancellation or invalidity — a different action, different evidence, more cost, lower odds. Worth knowing early: a holder whose own book is largely lapsed or withdrawn is more vulnerable to a non-use challenge than the register first suggests.

The same question, answered per register.
