Design invalidity: costs drivers
Design invalidity proceedings run on paper, evidence and deadlines, not on courtroom hours. Costs rise with the number of prior-art documents, the number of jurisdictions those documents come from, and whether the other side contests every ground raised. A one-ground, well-documented case costs a fraction of a multi-ground dispute with translated evidence.
What changes in timing and risk
Once an invalidity application is filed against a registered design, the registration remains valid until a decision is issued. The applicant carries the burden of proving the ground raised — usually lack of novelty or lack of individual character against an earlier disclosure. The holder can respond, request an extension, or let the deadline pass. Each of these choices moves the timeline and the eventual cost.
Extensions are common and rarely refused on first request. A case with two extensions on each side can add several months before the file even reaches a decision-maker. The practical effect: a straightforward file may close within a year, while a contested one with expert evidence and cross-references to parallel disputes can run well beyond that.
Costs drivers at a glance
| Driver | Effect on cost |
|---|---|
| Number of prior-art sources | Each additional source needs its own evidence chain and dating proof |
| Jurisdictions of origin of the evidence | Foreign-language material needs certified translation |
| Number of grounds raised | Each ground is assessed and argued separately |
| Whether the holder responds | A silent holder shortens the file; a contesting holder extends it |
| Expert or technical evidence | Adds preparation time and a further round of observations |
| Appeal by either side | Restarts written proceedings at a higher instance |
What to do
- Gather the earlier design, product or publication that predates the registration, with a clear, provable date.
- Instruct your representative to draft the grounds around the strongest single disclosure first, not the widest list.
- Translate any evidence that is not in the language of the proceedings before filing, not after a deficiency notice.
- File the application with the fee paid in full; an unpaid or partial fee is treated as if nothing was filed.
- Track the response deadline given to the holder and calendar the extension windows in advance.
- Decide early whether an appeal is realistic if the decision goes against you — it changes how much evidence to front-load now.
Who decides
The first-instance decision-maker is the body handling the register where the design sits. It works from written submissions only; there is no hearing unless one is specifically requested and granted. A decision typically closes the file at first instance within twelve to eighteen months from filing, depending on extensions and evidence volume.
Either side can appeal a first-instance decision to a higher board within the same office, usually within a short fixed window from notification. If you are weighing whether to prepare for that stage now rather than after a loss, Appeal against a first instance decision sets out the documents to prepare in advance.
Point of no return
Once the written phase closes and a decision is scheduled, new evidence is no longer accepted. Filing evidence after that point is treated as late, and late evidence is usually disregarded regardless of relevance. This is the practical point of no return: everything material must be in the file before the office signals closure, not after.
Forks
- If the holder does not respond at all, the file can close faster and at lower cost, but the decision may still require the applicant to prove every element of the ground raised.
- If the disputed design sits inside a wider technology supply arrangement, exit obligations under that arrangement may run on a separate track — see Exit assistance technology contract how it is proved explained.
- If the design underlies a tokenised or digitally represented asset, transitional rules on that asset may apply independently of the invalidity outcome — see What changed in reserve rules token issuance the transition.
Predel
This page does not cover infringement proceedings, only invalidity of the registration itself. It does not set out fee schedules, which are published separately and change independently of procedure. It does not replace an assessment of your specific evidence — a weak prior-art date can undo an otherwise strong case regardless of how the procedure is run.

If what you need is not a procedure but a full inventory of registered rights held within one jurisdiction, that is a different exercise from an invalidity filing. For that scope, see Asset in Italy in detail.

FAQ
How long does design invalidity take in practice?
A single-ground, undisputed file can close within a year. A multi-ground file with extensions and expert evidence commonly runs beyond eighteen months, and an appeal adds a further round of written proceedings.
Which documents are needed to start?
You need the earlier design, product image or publication with a provable date, a clear statement of the ground relied on, and certified translations of any foreign-language evidence before filing.
What happens if the other side does not respond?
The file proceeds on the applicant's submissions. The decision-maker still checks that the ground is proven; silence from the holder shortens the timeline but does not guarantee an outcome.
