Design invalidity: what the decision maker looks at
An application for a declaration of invalidity asks the office to conclude that a design should never have been registered. The decision maker checks novelty, individual character, and any absolute ground for refusal that applies to the specific right. It does not weigh commercial harm, and it does not judge the good faith of the person who filed.
What the decision maker actually checks
Every request has to name at least one ground, and the office decides only the grounds actually raised. Novelty and individual character are argued most often, compared against a design that already existed before the filing date. A design that copies an earlier trade mark, a copyright work, or another registered design fails on that separate conflict, regardless of how novel it otherwise looks.
| Ground raised | What the file must show |
|---|---|
| Lack of novelty | An earlier design disclosed anywhere before the filing date, identical or differing only in immaterial details. |
| Lack of individual character | An earlier design producing the same overall impression on an informed user, allowing for the designer's normal degree of freedom. |
| Purely functional appearance | Features dictated solely by technical function, leaving no room for aesthetic choice. |
| Conflict with an earlier right | An earlier trade mark, copyright work, or design that the later registration reproduces without consent. |
| Wrong applicant | Evidence that the person who filed the registration was not entitled to do so. |
Purely functional features are excluded from protection entirely. The test asks whether the appearance was dictated by technical necessity, not by choice. Entitlement disputes ask a different question again: whether the person who filed actually had the right to file, which the decision maker checks separately from how the design looks.
What to do before filing
- Locate the earlier disclosure. Find the publication, sale record, or catalogue entry that shows the same design before the filing date; an exact date matters more than volume of material.
- Build a side-by-side comparison. Set the earlier design and the registered design next to each other, feature by feature, from the viewpoint of an informed user.
- Confirm standing to file. Some grounds are open to anyone; others are reserved for the holder of the conflicting right, so check this before drafting anything else.
- Anticipate the reply. The registration holder will dispute dates, scale, or materials; prepare the response to those points now rather than after the first exchange.
- Fix the wording inside the file early. Precision in definitions decides cases on their own — what redemption token issuance means in a file shows how a single defined term shifted an unrelated dispute.
- Decide on representation before the office. A registered representative manages correspondence, but the evidentiary record — the same documentary discipline that governs acceptance testing regime in technology contracts — has to exist before instructions are given.
Who decides and how the file moves
The request goes to the office's dedicated invalidity division, not to the examiner who granted the registration. That division decides on the papers alone in most cases; oral proceedings are the exception, not the rule. Its decision is reasoned in writing and covers every ground that was actually argued.
If the outcome goes against either side, the next step is an internal appeal, followed by judicial review beyond that. Appeal against a first instance decision sets out the stages and deadlines that apply once a first-instance ruling in a comparable IP file is challenged.
| Stage | What happens | Indicative timing |
|---|---|---|
| Filing | The invalidity request is lodged with the grounds and initial evidence attached. | A few weeks to prepare |
| Admissibility check | The office confirms the request is complete and any fee has been paid. | Days to a few weeks |
| Exchange of observations | The registration holder replies; further rounds follow if new points are raised. | Several months |
| Decision | The office issues a written decision on each ground raised. | Around a year from filing, longer in contested files |
| Appeal, if lodged | Either side may contest the decision before a higher instance. | An additional year or more |
If your situation is different
If you hold the registration and the request looks weak, respond within the office's deadline and put the burden back on the evidence, rather than arguing character alone.
If you are filing the request and the earlier disclosure is recent, check the date first. A disclosure inside the grace period the registration holder can rely on defeats novelty and individual character alike.
If the design is already the subject of parallel litigation, coordinate the timing. A national infringement case can be stayed pending the invalidity outcome, or the two can run side by side.
Sources and limit
This page describes the shape of a design invalidity request: the stages, the decision maker, and the kind of file that supports each ground. It does not value what a design is worth, and it does not price what happens if a registration is lost while a business still relies on it.
Each stage described above can carry an official fee, published separately by the relevant office; this page does not state amounts, since fee schedules change and belong to the office, not to a commentary page.

FAQ
How long does design invalidity take in practice?
A straightforward, unopposed request can close within a year of filing. A contested file with multiple exchanges, and an appeal afterwards, commonly runs well beyond that, sometimes into a second year or more.
Which documents are needed to start?
At minimum: dated proof of the earlier disclosure, a side-by-side comparison against the registered design, and evidence of standing to bring the specific ground raised. Missing dates are the most common reason a request fails early.
What happens if the other side does not respond?
The office still decides on the merits of what was filed; silence is not an automatic win. The party seeking invalidity still has to prove every element of the ground raised, with or without a reply.
