How to Sue for Design Infringement in France (2026): Procedure, Evidence, Timelines and Remedies

Design infringement France actions are among the fastest and most decisive enforcement routes available to brand owners and product manufacturers anywhere in Europe, which is why design-intensive businesses increasingly treat France as a frontline jurisdiction for protecting the visual identity of their products. In 2026, with counterfeiting pressures rising across fashion, consumer goods and industrial design, rights-holders want predictable, enforceable remedies that move in weeks rather than years. This guide sets out, step by step, how to bring a design infringement claim in France, from preserving evidence and securing urgent relief through to the main action, concurrent invalidity battles, remedies and realistic timelines. It is written for in-house counsel, IP managers and outside counsel who need actionable procedure, not theory.

Why Sue for Design Infringement in France in 2026?

France offers one of the most litigant-friendly environments in the European Union for enforcing design rights. The combination of the saisie-contrefaçon (a court-authorised evidentiary seizure), rapid interim relief through the référé procedure, specialised judges and effective customs cooperation makes it a natural venue for rights-holders seeking to stop infringement at speed. The substantive law is set out in the Code de la propriété intellectuelle (French Intellectual Property Code), supplemented by EU-level design protection administered through the EUIPO.

Which country is best for intellectual property law? There is no single answer, but for designs France consistently ranks among the strongest European choices because it couples powerful pre-action evidence tools with concentrated judicial expertise. A single national action can enforce both French registered designs and EU-wide Community designs, giving claimants reach well beyond France’s borders. For design-heavy sectors in 2026, where product cycles are short and copycats move fast, that speed advantage is often decisive. A successful design infringement France strategy typically blends urgent measures with a well-prepared main action, so that the infringer is stopped quickly while damages and final orders are pursued in parallel.

Quick Checklist: Before You Sue for Design Infringement in France

Before launching any design infringement France claim, a short window of preparation often determines the outcome. Evidence disappears quickly, and the strength of your urgent application depends on what you capture in the first days.

Immediate steps, preserve evidence, appoint counsel, identify defendants

• Preserve evidence. Purchase and date-stamp infringing samples, capture listings, screenshots and invoices, and secure your own design registration certificates and priority documents.
• Appoint specialist counsel early. A saisie-contrefaçon must be authorised by a court before it is executed, so instructing an experienced IP litigator at the outset is essential.
• Identify the defendants. Map the supply chain, manufacturer, importer, distributor and retailer, because each may be a legitimate target and each seizure location may need separate authorisation.

Consider urgent measures, saisie-contrefaçon, interim injunctions and customs

• Evidentiary seizure. Decide whether a saisie-contrefaçon is needed to lock down proof before the infringer reacts.
• Interim injunction. Assess whether a référé application can halt sales or imports while the main action proceeds.
• Customs action. File a right-holder application with customs to intercept infringing imports at the border.

These six points form a practical pre-action checklist that counsel can refine into a tailored enforcement plan for your specific design portfolio.

Grounds for a Design Infringement Claim in France

Every design infringement France action begins with establishing a valid, enforceable right and then proving that the defendant’s product reproduces or closely resembles it. Understanding exactly what is protected, and under which regime, shapes the entire strategy.

What is protected, French registered designs vs EU Community designs

Rights-holders in France can rely on several overlapping forms of protection:

• French registered designs. Protected under the Code de la propriété intellectuelle following registration with the INPI (Institut national de la propriété industrielle, the French IP office). Protection is granted for an initial period and may be renewed in successive periods up to a maximum statutory term.
• Registered Community Design (RCD). A single registration at the EUIPO that covers all EU member states, enforceable before French courts acting as Community design courts. Following the EU designs reform, this right is now generally referred to as a registered EU design.
• Unregistered Community Design (UCD). Arising automatically on first disclosure in the EU and protecting against copying for a limited period, useful for fast-moving sectors such as fashion where products are rarely registered.

The WIPO designs resources provide a helpful overview of how national and EU rights interact with international design systems, which matters when planning cross-border enforcement. A design to be valid must generally be new and possess individual character, points that recur when validity is challenged in response to an infringement claim.

Legal test for design infringement, overall impression

The core test for infringement is whether the allegedly infringing product produces the same overall impression on the informed user as the protected design. This is an impression-based assessment rather than a feature-by-feature comparison, though individual features carry weight. The degree of design freedom available to the designer in the relevant sector influences the analysis: where freedom is wide, even modest differences may avoid infringement; where freedom is constrained by function, closer similarities may still be lawful.

For unregistered rights, the claimant must additionally show copying, whereas registered rights protect against independent creation producing the same overall impression. This distinction is central to any design infringement France case and should be settled early, because it determines the evidence you will need to assemble.

Pre-Action Evidence and the Saisie-Contrefaçon

The saisie-contrefaçon is the single most powerful pre-action tool in French IP litigation and the feature that most distinguishes a design infringement France strategy from enforcement in common-law jurisdictions. It allows a rights-holder to obtain court-ordered, on-site preservation of proof before the opponent has any chance to conceal it.

What is saisie-contrefaçon and when to use it

A saisie-contrefaçon is a court-authorised evidentiary seizure provided for in the Code de la propriété intellectuelle, with procedural rules governed by the Code de procédure civile. On the strength of your design right, a judge authorises a court-appointed enforcement officer, the commissaire de justice (the profession that replaced the former huissier de justice), to enter specified premises and document, describe and in some cases physically seize infringing goods, moulds, invoices and commercial records. The order is obtained ex parte, meaning the target has no advance warning.

Use it whenever proof of infringement, or the scale of infringement, is at risk of disappearing, which is almost always the case with mobile stock, online sellers or trade-fair displays. The saisie-contrefaçon design evidence captured in this way frequently becomes the backbone of both the interim application and the main damages claim, because it establishes volumes, pricing and distribution channels that the claimant could never obtain voluntarily.

Practical steps, officer, scope, photographs, sampling and chain of custody

Executing a seizure effectively requires careful planning:

• Define the scope precisely. The petition to the court must identify the premises, the goods and the categories of document sought. An overbroad request risks refusal or later annulment.
• Appoint the right officer and experts. The commissaire de justice may be accompanied by an independent technical expert, a photographer and, where appropriate, an IT specialist for digital records.
• Document meticulously. Photograph products in situ, record serial numbers, take representative samples and list seized documents in the officer’s report (procès-verbal), which has significant evidential weight.
• Protect the chain of custody. Seized items and copies must be sealed, inventoried and handled so that their integrity cannot be challenged at trial.

Risks and protections, sealing, costs and sanctions for abuse

The saisie-contrefaçon is powerful but not without constraints. The claimant must normally commence the main infringement action within a short statutory period after the seizure, failing which the measure can be annulled and the seized evidence excluded. Confidential business material belonging to third parties may be sealed pending a court ruling on disclosure. Crucially, abusive or disproportionate use of the procedure can expose the claimant to damages. The courts expect the measure to be proportionate to a genuine suspicion of infringement, and a defendant who shows the seizure was wrongful may recover compensation, a real risk that disciplines how any design infringement France seizure is framed.

Urgent Interim Relief and Border Measures

Once evidence is secured, the next question is how quickly the infringement can be stopped. France offers two complementary fast routes: the interim injunction through référé proceedings, and customs seizure of infringing imports.

Interim injunction (référé), standard, timing and evidence

The référé is a summary procedure under the Code de procédure civile that allows a claimant to obtain a provisional injunction to halt sales, manufacture or imports pending the full trial. The claimant must show a credible, arguable case of infringement, a prima facie case rather than conclusive proof. Hearings can be fixed quickly, and in genuinely urgent cases an order may be obtained on an accelerated basis.

Because the standard is lower than at trial, an interim injunction design France application is often the quickest way to protect market position, particularly ahead of a key selling season. Evidence gathered through a prior saisie-contrefaçon materially strengthens the application, which is why the two measures are frequently sequenced together. The court may order the injunction subject to the claimant providing security, protecting the defendant if the claim ultimately fails.

Customs measures, intercepting infringing imports

Where infringing goods are manufactured abroad, border enforcement can be the most cost-effective option. A rights-holder can file an application for customs action under the EU customs enforcement framework, enabling French and EU customs authorities to detain suspected infringing goods on entry. Once goods are detained, the rights-holder is notified and can confirm infringement, triggering destruction or further legal steps. The EUIPO and French Customs (Douane) provide guidance on how design rights fit within the EU customs enforcement framework. Close coordination between counsel and customs officers improves detection, so sharing product identifiers and known shipping routes is worthwhile.

Which remedy to use when, a decision tree

In practice, the sequencing follows a logical path: capture proof through a saisie-contrefaçon; stop the infringement rapidly through a référé injunction; block cross-border supply through customs; and pursue final remedies through the main action. Not every case needs all four, but the strongest design infringement France campaigns deploy them in a coordinated sequence rather than in isolation.

Starting the Main Infringement Action, Procedure and Timelines

The main action is where final remedies, damages, destruction and publication orders, are secured. While slower than interim relief, it delivers the decisive outcome and is often shaped by everything that happened in the urgent phase.

Forum and competent court

Design infringement actions in France are heard by designated tribunaux judiciaires with specialised IP jurisdiction. The Tribunal judiciaire de Paris has exclusive jurisdiction over EU design (Community design) matters and concentrates a significant share of design litigation. Because specialised judges handle these disputes regularly, decisions tend to be technically sound and reasonably consistent, which assists parties in predicting outcomes and assessing settlement value.

Typical timeline from filing to judgment

Interim measures can be obtained in days to weeks. The main action is slower: from filing to first-instance judgment, parties should typically plan for a period measured in many months to around two years, depending on complexity, the number of defendants, the need for expert input and whether validity is contested. Appeals extend the timeline further. The practical consequence is that the interim injunction frequently dictates the commercial reality long before the final judgment is handed down, which is why so much effort goes into the early stages of any design infringement France case.

Evidence, expert reports and discovery limits

France does not have broad common-law style discovery. Instead, claimants build their case through documents they already hold, the saisie-contrefaçon report and, where needed, court-appointed or party expert evidence on technical and valuation questions. The absence of wide-ranging disclosure is precisely why the saisie-contrefaçon is so important: it is a principal mechanism for obtaining evidence from the opposing side. Expert reports are commonly used to address the overall impression test and to quantify damages, and the court retains control over the evidentiary process throughout.

Concurrent Invalidity Actions: INPI and EUIPO Routes

A design infringement France claim rarely proceeds without the defendant attacking the validity of the right asserted against them. Anticipating and managing that counterattack is a core part of litigation strategy.

When to challenge validity vs defend

Validity and infringement are two sides of the same dispute. A claimant must be confident that the asserted design is new and has individual character, because a defendant will almost invariably argue that the design was anticipated by prior art or lacks individual character. Conversely, a party facing an infringement claim may take the initiative and seek to cancel the right. Deciding whether to lead with invalidity or hold it in reserve as a defence depends on the strength of the prior art, the forum and timing considerations.

Procedure before INPI and the EUIPO, and impact on litigation

For French registered designs, invalidity can be pursued before the INPI through its administrative cancellation procedure, as well as before the courts. For registered EU (Community) designs, invalidity is handled by the EUIPO, with appeals through its Boards of Appeal and the EU courts. A pending invalidity action can influence the infringement proceedings, a court may, in appropriate circumstances, manage the timetable to account for a parallel validity challenge. Because the forum for invalidity may differ from the forum for infringement, coordinating the two tracks is essential to avoid inconsistent outcomes and wasted cost.

Remedies and Damages for Design Infringement in France

The remedies available are what make a design infringement France action worthwhile commercially. They range from fast provisional measures to comprehensive final orders.

Preliminary remedies

Before final judgment, the key provisional remedies are the saisie-contrefaçon (to preserve evidence) and the interim injunction (to stop the infringing activity). Customs detention also operates as a practical preliminary remedy by preventing infringing goods from reaching the market. Together these measures can neutralise the commercial harm long before the court rules on the merits.

Final remedies, damages, destruction, recall and publication

On a finding of infringement, the Code de la propriété intellectuelle enables the court to grant a comprehensive package of final remedies:

• Permanent injunction. A definitive order to cease manufacture, sale and importation, typically reinforced by a periodic penalty payment (astreinte) for non-compliance.
• Damages. Monetary compensation for the harm suffered, assessed on the statutory criteria set out in the IP Code.
• Destruction and recall. Orders for the destruction of infringing stock, materials and tools, and recall of goods from the channels of commerce.
• Publication. Orders to publish the judgment, which carries reputational weight and deters other infringers.

Quantifying damages

French courts assess damages for design infringement France by taking into account the negative economic consequences for the claimant (including lost profits), the moral prejudice suffered, and the profits made by the infringer. Alternatively, at the request of the injured party, damages may be set as a lump sum assessed by reference to at least the royalties that would have been due had the infringer requested authorisation. The Cour de cassation has shaped the principles courts apply when quantifying harm.

Practical Considerations: Costs, Security and Appeals

Cost and risk management are integral to any realistic enforcement plan, and should be assessed before the first application is filed.

Court fees, expert fees and counsel fees

The principal costs of a design infringement France action are counsel fees, the enforcement officer’s fees for any saisie-contrefaçon, and expert fees where technical or valuation evidence is required. Interim measures are relatively contained in cost; the main action, particularly where validity is contested and experts are instructed, is significantly more expensive. A court may require the claimant to provide security when ordering provisional measures, to cover the defendant’s potential loss if the claim later fails. The successful party can usually recover a contribution to its costs under the applicable procedural rules, though recovery rarely covers the full outlay.

Appeals and enforcement of judgments

First-instance judgments can be appealed to the Court of Appeal (cour d’appel), and a further appeal on points of law lies to the Cour de cassation. Provisional enforcement of first-instance judgments is, as a general rule, available by default, meaning an order can take effect pending appeal, which preserves the claimant’s commercial advantage. Judgments are enforced through the usual civil mechanisms, and injunctions backed by an astreinte create a strong financial incentive for compliance.

Tactical Checklist and Sample Timeline

A disciplined design infringement France campaign tends to follow six stages: (1) secure and date evidence of the infringing product and your own rights; (2) instruct specialist counsel and obtain authorisation for a saisie-contrefaçon; (3) execute the seizure and preserve the chain of custody; (4) apply for an interim injunction and file customs action; (5) commence the main action within the statutory deadline; and (6) pursue final remedies, damages and, where necessary, appeal. Mapping your matter against these stages at the outset helps you anticipate cost, deadlines and decision points before momentum is lost.

Comparison Table: Remedies and When to Use Them

Conclusion

A design infringement France action rewards speed, preparation and coordination. The jurisdiction’s distinctive combination of the saisie-contrefaçon, rapid référé injunctions, effective customs enforcement and specialised courts means a well-planned campaign can stop an infringer quickly and secure comprehensive final remedies at trial. The key is to sequence the tools correctly, preserve evidence first, obtain urgent relief, block imports, then pursue the main action and damages, while anticipating the validity counterattack that almost always follows.
