Opposition proceedings: documents to prepare
An opposition against a trade mark application must be filed within the statutory window after publication, and the file needs a formal notice, proof of standing, and evidence supporting the grounds. Missing a single supporting document does not stop the clock — it narrows what the opposition can later argue.
What starts the clock
The opposition period begins on the date the application is published for opposition purposes, not on the date it was filed. The applicant and the opponent then usually enter a cooling-off period, during which either side may ask for more time to negotiate a settlement. Once that period ends without an agreement, the office sets a schedule for written submissions.
Each deadline in that schedule runs independently. Missing one does not automatically end the case, but it does close the door on whatever that deadline was meant to cover.
Documents to prepare
The file needed at the outset differs from the file needed once the case moves into substantive rounds. The table below groups documents by the stage where they usually matter.
| Stage | Document | Purpose |
|---|---|---|
| Filing the opposition | Notice of opposition | States the grounds relied upon and identifies the earlier right |
| Filing the opposition | Proof of standing | Shows the opponent holds or represents the earlier right |
| Cooling-off | Settlement correspondence | Records coexistence or licence discussions, kept outside the formal file |
| Substantiation | Registration certificate or extract | Confirms scope, class and current status of the earlier right |
| Substantiation | Proof of use | Required only if the applicant challenges use of the earlier right |
| Substantiation | Translation of exhibits | Needed whenever evidence is not in the language of the proceedings |
A file that arrives complete at the substantiation stage rarely needs a second round of requests from the office. A file assembled piece by piece almost always does, and each request adds weeks rather than days.
What to do before filing
- Confirm the current registration status of the earlier right with the relevant office before drafting anything.
- Check whether the mark has been registered long enough to face a non-use challenge, and if so, locate use evidence in advance.
- Draft the notice of opposition naming every ground relied upon; grounds left out cannot be added once the deadline passes.
- Instruct a translator for any exhibit not in the language of the proceedings, well before the substantiation deadline.
- File within the statutory opposition window; a late filing is not admitted, regardless of how strong the underlying right is.
How the file is assembled
Good practice keeps every exhibit labelled, dated and cross-referenced before it reaches the file, not after a deficiency letter arrives. The same discipline is described from a different angle in How benchmarking clause technology contract documents to prepare runs, where the comparison points are contractual rather than registrable rights.
When proof of use relies on a sworn statement rather than an official register extract, that statement functions much like the attestation discussed in What attestation token issuance means in a file: a third party vouches for a fact the office cannot verify on its own.
Who decides and how long it takes
The office handling the underlying application decides the opposition on the merits, unless the parties settle first. A first-instance decision typically follows several rounds of written submissions, each carrying its own response deadline. Either party may appeal, which restarts the clock before a separate appellate body.
Where a dispute sits alongside a pending licence or a settlement already under discussion, the timing questions look similar to those in Settlement and licence on judgment, even though the forum differs.
Forks in the file
If the other side does not respond within its deadline, the office may decide on the file as it stands. That usually favours the opponent on the points left unanswered.
If the applicant requests proof of use, the opponent must produce use evidence for the relevant period, or the opposition fails on that ground alone, regardless of the other grounds pleaded.
If the parties reach a coexistence agreement, the opposition is typically withdrawn rather than decided, and the file closes without a ruling on the merits.
What this page does not cover
This page describes the opposition procedure and the documents it requires. It does not price the work of assembling a file, and it does not tell you how many registers or jurisdictions your portfolio touches before a licence is signed. That question is covered in Asset report before a licence is signed: the deadline.

This page describes the procedure as published in the relevant trade mark office's own guidance on opposition proceedings. No fee amounts or article numbers are quoted here; the office handling your application publishes its own current schedule and deadlines, and those should be checked directly before any filing.
FAQ
How long does opposition proceedings take in practice?
Timing depends on whether the parties use the cooling-off period, how many rounds of submissions follow, and whether either side appeals. A case settled during cooling-off closes in weeks. A contested case that goes to appeal can run for well over a year.
Which documents are needed to start?
At filing, you need a notice stating the grounds and a document proving the opponent's standing to rely on the earlier right. Evidence substantiating the right itself, including proof of use where relevant, follows at a later stage rather than at filing.
What happens if the other side does not respond?
The office proceeds to decide on the file as submitted. Silence is not treated as an admission, but it removes the chance to contest whatever was left unanswered, which usually works against the silent party.
