Opposition proceedings: what the decision maker looks at
The decision maker weighs three things: the validity of the earlier right, the similarity between marks and goods, and proof of genuine use where use is challenged. Everything filed after the notice serves one of these points, or it is set aside as irrelevant.
What the decision maker actually looks at
Six elements recur in almost every opposition file, regardless of the office running the case.
- Standing and validity of the earlier right. The opponent must hold a right that still exists and covers the goods or services relied on.
- Similarity of the signs. Visual, phonetic and conceptual similarity are assessed separately, then combined.
- Similarity of goods and services. Overlap is read from the register entry, not from how either side currently trades.
- Distinctiveness of the earlier mark. A highly distinctive mark is given a wider zone of protection than a descriptive one.
- Proof of genuine use. If the earlier right is old enough, the applicant can force the opponent to show real commercial use, not registration alone.
- Any defence raised. Consent, coexistence agreements and honest prior use are argued at this stage, not later.
Nothing outside these six lines carries independent weight. Reputation, marketing spend and industry standing matter only insofar as they support one of the six points above.
How evidence is weighed
An official register extract proves the earlier right's existence on its face; the decision maker rarely questions it further. A sworn statement alone, without supporting invoices or catalogues, carries far less weight and is often treated as self-serving.
Invoices, price lists and dated marketing material are read together, not in isolation. A single invoice proves a single sale; a pattern across the relevant period proves use. Undated material is set aside regardless of how persuasive it looks on its face.
Translations matter more than parties expect. If evidence is filed in a language the office does not use for the proceeding, an untranslated document can be disregarded entirely, not merely discounted.
What changes once an opposition is filed
Filing an opposition stops the challenged mark from completing registration while the case remains open. The applicant cannot rely on the mark commercially with full certainty, and any licence, assignment or security interest negotiated during this period should disclose the pending challenge.
The clock that matters here is not a court date. It is the sequence of notices the office issues to both parties, each one opening a fixed window for a reply. Missing a window closes that stage; it does not pause the case.
What this page does not settle
This page describes what an opposition examiner weighs; it does not tell you whether your own mark will survive a particular challenge, which turns on the actual evidence in your file. It does not set the national filing or reply deadlines, which are stated in the notices the office sends, and it does not replace a reading of the specific grounds raised against you.
FAQ
What does the decision-maker look at first?
Whether each claimed ground is supported by dated, translated evidence that covers the relevant period. Material that is undated, untranslated, or outside the period is set aside before the substance is weighed.
Which deadline is already running?
The reply window opened by the last notice the office issued. It runs from the date on that notice, not from the day you read it, and missing it closes that stage of the case rather than pausing it.
Who decides, and on what evidence?
The opposition division of the office decides first, on the filing record, the evidence of use, and any agreement between the parties. Its reasoned decision can usually be challenged before a separate appeal body inside the same office.
