When a similar mark is filed in your class: what to do first
A similar mark filed in the same class starts a clock, not an automatic conflict. The task right now is threefold: confirm the filing details, check whether the opposition period is still running, and decide whether to oppose, negotiate, or simply monitor. Silence is read as no objection, not as a pause.
The basis
Examination, publication, and opposition of a European Union trade mark follow Regulation (EU) 2017/1001 (EUTMR). The regulation sets the framework within which a published application can be challenged before it proceeds to registration. It does not fix a single European response by itself: national offices apply their own procedural rules alongside it, and the period for filing an opposition is set within that framework rather than announced case by case.
The practical point is narrower than the regulation itself. A published application is a fact with a clock attached. The clock runs regardless of whether anyone in your organisation has noticed the publication yet.
What changes for you
If the opposition period lapses without action, the later mark can proceed to registration undisturbed. A challenge after that point shifts from opposition to a cancellation action, which is slower, carries a heavier evidentiary burden, and unfolds after the mark is already on the register rather than before. The order of operations, not just the underlying similarity, decides how expensive the dispute becomes.
| Factor | Effect on the route |
|---|---|
| Class and goods overlap | Full overlap supports opposition; partial overlap narrows the argument to specific goods or services |
| Deadline status | Running favours opposition; lapsed forces a cancellation action instead |
| Prior use evidence | Available evidence supports either negotiation or opposition; absence weakens both |
| Applicant identity | A known competitor changes the settlement calculus compared with an unrelated third party |
What to do
- Confirm the filing: class, list of goods and services, filing date, and applicant, using the register entry itself, not a summary of it.
- Check the deadline: identify the publication date and treat it, not the date you noticed the filing, as the trigger for the opposition period.
- Compare the marks and the goods side by side, without assuming that a partial overlap in wording settles the question.
- Decide the route: opposition, negotiated coexistence, or monitoring without action, and record the reasoning behind the choice.
- If opposing, assemble the evidence of prior rights and use before drafting the notice of opposition.
- File within the period through the responsible office, using the form and channel that office requires.
Who decides
The relevant intellectual property office examines the opposition on the papers filed, unless a hearing is requested by one of the parties. The outcome turns on the strength of the prior right and the evidence of similarity submitted within the procedure, not on which side filed first or shouted loudest. The office does not investigate facts that neither party puts before it.
Branches
If you also hold a patent under pressure from a filing next to your own product, the triage is the same: confirm, check the deadline, decide the response — What to do first in this situation and who.
If the pressure sits inside a supply or software contract rather than a register, the decision-maker and the forum change, but the discipline of confirming the clock before reacting does not — When a customer demands unlimited liability: what to do.
If the conflict touches a token offering document rather than a mark, the same first move applies before any deadline closes — When the offering document is questioned and its limits.
Sources and limits
This page describes the mechanism, not a filed opposition. It does not run your deadline for you, and it does not substitute for a watch service that flags publications the day they appear. Where the conflict concerns a specific asset registered in Lithuania and needs continuous tracking rather than a one-off opinion, that is a tracked file — Asset in Lithuania and the deadline.

A similar mark in your class is a fact to act on, not an argument to win by delay. Confirm the filing, hold the deadline in view, and choose the route deliberately rather than by default.
FAQ
What is the first step when a similar mark is filed in your class?
Confirm the filing details and check the opposition period before anything else. Everything that follows depends on that one fact being right.
Which deadline is already running?
The opposition period set within the applicable regulation, counted from the publication date of the application. Treat the publication date, not the date you noticed it, as the start.
Who decides, and on what evidence?
The relevant intellectual property office decides, based on the arguments and evidence filed within the procedure. It does not gather evidence on its own account.
