Seniority and priority claims: stages and deadlines
A seniority or priority claim lets a later trade mark or design application rely on the filing date, or on rights already recognised in an earlier application, instead of starting the clock from scratch. The claim runs alongside the new filing, moves through fixed stages, and lapses if the underlying right is abandoned or the deadline to file the claim is missed.
What changes once you file the claim
A successful claim shifts the relevant date backward. Anything filed by a third party between the earlier date and the later application no longer defeats your mark on that ground alone. The claim does not create a new right — it attaches an earlier date to an existing filing, and the attachment can be examined, questioned, or lost.
Two practical effects follow. First, the priority or seniority window is short and does not restart if you miss it. Second, the office handling the later application will check the earlier right independently — a claim is a request, not an automatic grant.
Stages, in order
| Stage | What happens | Typical trigger |
|---|---|---|
| Filing the claim | The claim is submitted together with, or shortly after, the new application, naming the earlier right | New application filed |
| Formal check | The office confirms the claim form is complete and the earlier right is identified correctly | Automatic, on receipt |
| Substantive examination | The office compares the goods, services, or design scope of the earlier and later right | After formal check clears |
| Notification | Applicant is told whether the claim is accepted, partially accepted, or refused | End of examination |
| Response window | Applicant may submit further evidence or narrow the claim before a final decision | Refusal notice issued |
| Final decision | Claim is recorded against the later right, or refused with reasons | Response window closes |
Each stage has its own short deadline. A missed deadline at the formal check stage usually means the claim is treated as never filed, not merely delayed.
Documents to prepare
- Certificate or extract confirming the earlier registration, current and in the applicant's name
- List of goods or services (or, for designs, the product indications) covered by the earlier right
- Proof that the applicant of the later mark and the owner of the earlier right are the same legal person, or evidence of a valid assignment chain
- Renewal evidence if the earlier right is close to its own renewal date
The document set is narrow but strict: a mismatch between the applicant name on the earlier certificate and the later application is one of the most common reasons a claim is queried. The same discipline around matching names and dates on prepared documents applies elsewhere — see Offering document preparation: documents to prepare for a comparable document-preparation stage in a different context.
Who decides, and how long it takes
The claim is decided by the office examining the later application, not by a court. Examination is administrative: an examiner checks the identity of rights and the match in scope, then issues a decision that can be appealed internally.
Timing depends on whether the claim needs further evidence. An uncontested claim with clean documents is usually resolved within the same examination cycle as the underlying application. A claim that triggers a query adds a response window before any decision issues. The logic an examiner applies — checking what the decision-maker actually looks at before accepting a claim — mirrors the review stage described in How escrow set-up technology contract what the decision maker.
If the other side does not respond
A seniority or priority claim is normally an ex parte matter between the applicant and the office — there is no "other side" unless a third party opposes the later application and disputes the claim as part of that opposition.
Where an opposition is filed and the opponent does not respond to a procedural step, the office generally proceeds on the record as it stands. Silence does not strengthen the claim, and it does not weaken it either. The claim is judged on the documents already filed, so an unopposed claim with complete documents is not at greater risk than an opposed one — provided the deadlines above were met.
Two scenarios
If your earlier right lapses before the claim is finally decided, the claim is examined on the record as it stood at filing, but the office will usually ask for updated proof of standing before confirming it. Renew the earlier right before it expires if a claim is pending.
If a competitor has already filed a conflicting application in the gap between the earlier and later date, the priority or seniority claim — once accepted — resolves that conflict in your favour on the filing-date point alone. It does not resolve a parallel enforcement question. A related timing situation, where the other side moved first on a different right, is set out in An injunction application is served patent when the other.
What this page does not cover
This page sets out stages and deadlines only. It does not cover the substantive test used to compare the scope of two rights, national variations in evidence requirements, or the fee schedule for filing a claim — these depend on the office and the specific right and are outside a general procedural page.
It also does not cover what can be established from a claim once granted, in the sense of a standalone factual record. For a structured example of what is publicly established for a comparable asset, see Asset in Gibraltar in detail.

FAQ
How long does seniority and priority claims take in practice?
An uncontested claim with complete documents is typically resolved within the same examination cycle as the underlying application. A queried claim takes longer because a response window is added before any decision.
Which documents are needed to start?
A current extract of the earlier right, its list of goods or services, proof that the applicant is the same owner or holds a valid assignment, and renewal evidence if the earlier right is close to expiry.
What happens if the other side does not respond?
Seniority and priority claims are usually examined without an opposing party. Where an opposition exists and the opponent stays silent, the office decides on the record already filed, without giving the silent claim extra weight.
