If a third party files an opposition against your trademark application and you do not respond within the given period, the BOIP or EUIPO will treat the matter as if you do not dispute the objections. This normally leads to a rejection of your application, either in full or for the part of the classes to which the opposition relates. The application does not disappear from the records, but formally receives the status of refused.
The consequence is tangible: no registration means no exclusive right to the name or logo in the classes concerned. You cannot simply resubmit the application afterwards without running into the same objections, because the party that filed the opposition retains their earlier right. What happens next depends on the stage the procedure is at and on the exact content of the opposition.
Why the office does not conduct an investigation on its own
The BOIP and EUIPO do not take an active investigative role in opposition proceedings. They await submissions from both parties and make a decision based on them. If the applicant fails to respond, there is simply nothing to set against the opposition. This is not a penalty for carelessness; it is the logical outcome of a procedure built on the principle of equal argument. Silence leaves the other party's argument unchallenged.
Which deadline you then miss
After an opposition is filed, you are given a period to respond, often preceded by a phase in which the parties can try to settle the matter between themselves. The exact length of these periods and how they relate to each other varies by procedure and is set out in the official rules of the BOIP or EUIPO. For the exact deadline that applies to your file, the letter or notice from the office itself is the reliable source, supplemented by the official texts on the office's website.
What often goes wrong in practice is not that entrepreneurs deliberately let the deadline pass, but that the notice simply goes unnoticed. A letter from the office lands in an inbox that no one checks daily, or an email gets lost among other business correspondence. By the time someone notices, the response deadline has already expired.
What you can still do if the deadline has already passed
Once an application has been rejected because there was no response, there is normally no straightforward way back within the same procedure. Some offices have an exceptional possibility to request restoration when force majeure can be demonstrated, but this is not automatic and the conditions for it are strict. Whether this has a realistic chance of success in a specific case is a question for a trademark attorney, not something we as a platform can advise on.
It is therefore especially important to act before the deadline expires. As soon as an opposition arrives, substantive assessment of the objections and conduct of the procedure itself are matters for a trademark attorney. marcai.eu guides the application and monitoring, but transfers a file to an attorney in case of opposition or refusal, precisely because this requires legal judgment that goes beyond a conflict search or class selection.
Why monitoring limits this risk without eliminating it
The greatest risk in opposition proceedings often lies not in the substance of the objection, but in timing. Continuous monitoring of new applications and signals relating to your own file reduces the likelihood that an opposition will go unnoticed and the deadline will expire without anyone knowing. This is precisely why marcai.eu, alongside the application itself, also alerts you as soon as something arises requiring action within the deadline — both when others file applications resembling your mark and when developments occur in your own file. If you would like to see how this alerting and handover to a representative works in practice, you can read about it on the page that explains step by step how the guidance works.
An opposition is not always well-founded, and not every opposition leads to a complete refusal. But whether an objection has prospects of success is a substantive question that falls outside the conflict search that marcai.eu performs beforehand. That search gives an indication of potential similarity before you file, not a guarantee that opposition will not arise later. If you would like to see in advance how your name stands, you can check it free and without an account.
What this means for the rest of your brand strategy
An application refused due to a missed opposition deadline does not affect only that one application. If you have already used the name on packaging, in marketing or on a website in the meantime, you continue to use the name without the exclusive right that registration provides. A competitor with an earlier right can challenge that use at a later stage, which is an entirely different and more serious procedure than the opposition at play here. For questions building on this, such as what changes if an application is already in use before registration becomes final, the knowledge base with frequently asked questions provides further background.
