A technology company incorporated in Germany launches its flagship product across French-speaking markets. Six months later, a competitor files an identical trademark in France. The German company had assumed its EU-wide registration covered its French operations comprehensively. It did not – and the window for filing an opposition was already closing.
IP portfolio management in France involves building and enforcing rights across trademarks, patents, designs, and copyright through the Institut National de la Propriété Industrielle (French National Intellectual Property Office, known as INPI). Registration at INPI is the primary gateway to enforceable rights in France. International companies must align their French IP registrations with their global portfolio strategy, typically within strict filing deadlines, to avoid gaps that competitors can exploit.
This guide covers the procedural requirements, step-by-step filing timelines, documentary checklists, common errors made by foreign clients, cost considerations, and a decision framework for structuring your IP portfolio in France across different business scenarios.
The French IP environment: what international companies face
France operates a dual-track IP system. At the national level, intellectual property legislation grants rights through INPI for trademarks, patents, and designs. At the supranational level, EU-wide instruments – the European Union trademark and the European patent via the European Patent Office – can extend to France as a member state. Understanding which track applies to your situation is the first structural decision every international company must make.
The instinct of many foreign businesses is to rely exclusively on EU-wide registrations. This approach has gaps. An EU trademark does not guarantee priority in French opposition proceedings when the filing dates differ. A European patent validated in France requires specific national validation steps. Missing those steps means the patent is unenforceable in French courts, even if it is valid elsewhere in Europe.
French intellectual property legislation provides robust protection, but only to those who claim it correctly and on time. The Cour de cassation (French Supreme Court) has consistently held that rights not properly registered or validated on the French national register cannot be invoked against French infringers in the same way that registered rights can. Unregistered rights – particularly in copyright – do exist under French law, but enforcing them without documentation is substantially harder.
For companies structured as a SARL (société à responsabilité limitée. the French limited liability company equivalent) or a SAS (société par actions simplifiée. a simplified joint-stock company), IP assets are typically held at entity level. Foreign companies establishing a French subsidiary must determine at incorporation whether IP rights will be owned locally or held at parent level and licensed down. The choice has tax, valuation, and enforcement consequences that interact directly with the provisions of the Code de commerce (French commercial code).
Practitioners in France note a recurring problem: international clients defer French IP filings because they assume their home-country or international registrations are sufficient. By the time a competitor or a former distributor challenges them, the filing window for priority has often closed.
Step-by-step: building an IP portfolio in France
The following steps apply to trademark registration as the most commonly needed instrument. Patent and design registration follow analogous sequences with different technical requirements.
Step 1 – IP audit and classification
Before filing anything, conduct a thorough audit of the assets your business uses in France. This includes brand names, product names, logos, packaging designs, software, and any manufacturing processes. Each asset maps to a different IP instrument. Trademarks protect names and logos. Patents protect inventions. Designs protect visual appearance. Copyright protects original works and arises automatically in France without registration.
For trademark filing, each asset must be assigned one or more classes under the Classification de Nice (Nice classification) – the international system that organises goods and services into 45 categories. A common error is filing in too few classes. A food brand that later enters the beverage sector may find its original registration does not cover the new product line. Adding classes later requires a new filing and a new fee – and creates a gap in the timeline that a well-advised competitor can use.
Step 2 – Prior art and availability search
Before filing a trademark application with INPI, conduct a prior art search to confirm the mark is available. INPI's online database – Bases Marques – is publicly accessible. Availability searches should cover identical marks, similar marks, and marks that could be confused with yours across your target Nice classification classes.
Do not skip this step. Filing a mark that conflicts with an existing registration triggers opposition proceedings. Opposition must be filed within two months of the publication of your application. If you are on the receiving end of an opposition, defending it adds months and legal costs. If you initiated the conflicting filing, you may be forced to withdraw and re-file under a modified mark – losing your original filing date entirely.
Step 3 – Preparing the trademark application
A trademark application filed with INPI requires: a clear representation of the mark, a list of goods and services organised by Nice classification. Identification of the applicant (name, address, legal form). Additionally, payment of the applicable government fee. For a foreign applicant without a registered address in France, INPI requires a domiciliation address – typically provided through a legal representative or a registered agent.
Applications may be filed electronically through INPI's online portal. The application date is the priority date. From that date, your rights exist provisionally while INPI examines the application.
For international companies, the Madrid System offers an alternative: file an international trademark application through the World Intellectual Property Organization (WIPO) and designate France. This is efficient when protecting a mark in multiple countries simultaneously. However, an international registration designating France is dependent on the base application for five years. If the base application is refused or cancelled, the international registration for France falls away. Companies that have already built a French customer base may prefer a direct INPI filing to avoid this dependency risk.
Step 4 – Examination and publication
INPI examines the application for formal compliance and for absolute grounds of refusal – marks that are descriptive, generic, or contrary to public order. INPI does not automatically examine for conflicts with existing registrations. That is left to third parties through the opposition process.
Once the application passes examination, INPI publishes it in the Bulletin Officiel de la Propriété Industrielle (Official Bulletin of Industrial Property). From publication, the two-month opposition window opens. Any registered trademark owner whose rights could be affected may file opposition.
Total time from application to registration, without opposition: typically four to six months for a straightforward application. If opposition is filed, proceedings extend the timeline by six to eighteen months depending on the complexity of the dispute and whether parties request extensions.
Step 5 – Opposition proceedings and negotiation
French opposition proceedings before INPI are adversarial but largely documentary. Each party submits written arguments and evidence. INPI's opposition division issues a decision. The losing party may appeal to the courts.
A non-obvious strategic option is negotiation during opposition. Many oppositions settle through coexistence agreements, in which both parties accept restrictions on how they use their marks. A coexistence agreement can be faster and cheaper than a full opposition proceeding, and it produces a contractual boundary that both parties have accepted.
International clients sometimes treat opposition as an automatic obstacle. In practice, a well-reasoned response accompanied by evidence of use in different markets or different product categories frequently succeeds. Practitioners in France note that INPI decisions in opposition proceedings are not always predictable, and the strength of the evidence record is decisive.

Step 6 – Registration and maintenance
Once opposition proceedings conclude – or the opposition window closes without challenge – INPI registers the mark and issues a certificate. The registration is valid for ten years from the filing date and is renewable indefinitely in ten-year increments.
Maintenance obligations matter. A French trademark is vulnerable to revocation for non-use if it has not been genuinely used in France for any consecutive five-year period after registration. Use must be real, commercial, and in the French market. Token use – a single sale, or use only in export markets – does not satisfy this requirement. Companies that register marks in France as a precaution, without active French operations, should implement a documented use strategy.
For patents, maintenance requires payment of annual renewal fees. Missing a renewal fee cancels the patent. Restoration is possible within a limited window, but the process adds cost and uncertainty. Calendar management for renewal dates is a basic but frequently neglected element of portfolio administration.
Enforcing IP rights in France: instruments and pitfalls
Registration creates rights. Enforcement gives them commercial value. French intellectual property legislation provides several enforcement instruments, each suited to different circumstances.
The saisie-contrefaçon
The most powerful enforcement instrument in French IP law is the saisie-contrefaçon (seizure of counterfeit goods and evidence). This is a court-ordered measure allowing the rights holder. assisted by a huissier de justice (French judicial officer. Roughly equivalent to a process server with enforcement powers). to enter premises and seize infringing goods and documents without prior notice to the defendant.
The saisie-contrefaçon requires judicial authorisation. The applicant presents a ex parte application to the presiding judge of the relevant commercial or civil court, demonstrating that they hold valid IP rights and that there is reason to believe infringement is occurring. If authorised, the seizure takes place with the huissier de justice present to document and preserve evidence.
This instrument is particularly valuable when the infringer may destroy evidence if given notice. It is also the standard first step before a full infringement claim. Evidence gathered through a properly conducted saisie-contrefaçon is admissible in subsequent proceedings. Evidence gathered without this procedure – for example, private investigations or unannounced visits by company employees – may be challenged and excluded.
A common mistake by foreign companies is attempting to gather evidence informally before consulting French counsel. The legal requirements for admissible evidence in a French infringement claim are strict. Evidence obtained outside the proper judicial channels creates procedural vulnerabilities that a competent defendant will exploit.
Infringement proceedings before specialist courts
France has designated specialist commercial courts for IP infringement claims. The Tribunal judiciaire of Paris has exclusive jurisdiction over trademark, patent, and design infringement cases of national significance. Regional courts handle matters within their geographic competence, but complex IP cases – particularly those involving patents – are almost invariably heard in Paris.
An infringement claim in France follows the standard civil procedure rules. The claimant must establish: valid IP rights, acts of infringement, and the causal link between the infringement and the loss claimed. French courts assess damages on the basis of the rights holder's actual loss, the infringer's profits attributable to the infringement, and, in certain circumstances, the moral prejudice to the rights holder.
The Cour de cassation has clarified that moral prejudice to a brand – damage to reputation and distinctiveness – is a compensable head of loss separate from economic damage. This is a meaningful difference from some other jurisdictions, where moral prejudice awards are minimal or unavailable. For international companies, this means that a French infringement claim can recover more comprehensively than a comparable action in some common law systems.

Customs and border measures
French customs authorities can detain goods suspected of infringing trademarks or other IP rights at the border. Rights holders can file a customs action request with French customs (DGDDI), identifying their registered rights and the goods at risk. If customs officers detect suspect goods, they notify the rights holder, who then has a limited period to confirm the infringement and request destruction or seizure.
Border measures are particularly relevant for companies in consumer goods, fashion, pharmaceuticals, and electronics – sectors where counterfeiting is widespread. However, they require current, valid French or EU registrations. Unregistered rights cannot be enforced at the border.

Cross-border portfolio strategy: France within a European and global context
For most international companies, France is one node in a broader IP portfolio. Decisions made for French filings interact with EU-wide strategies, international registrations, and home-country rights. Managing these interactions is where value is either preserved or lost.
EU trademark and French national filing: the trade-off
An EU trademark (EUTM) registered with the European Union Intellectual Property Office (EUIPO) covers all EU member states, including France. It is cost-efficient when a company operates across multiple EU markets. A single EUTM filing replaces 27 national filings.
However, the EUTM has vulnerabilities. A successful challenge to the EUTM in any member state can invalidate it across the entire EU. A French national trademark can be challenged only in French proceedings. Companies with significant French operations sometimes maintain both: an EUTM for EU-wide coverage and a French national mark as a fallback that survives an EU-level challenge.
The filing date of the French national mark can also predate the EUTM if the company entered France before expanding EU-wide. That earlier priority date strengthens the company's position in any opposition or infringement proceeding.
Patent strategy: European Patent Office versus direct French filing
European patents granted by the European Patent Office require national validation to take effect in each designated country. In France, validation requires filing a translation if the patent was granted in English or German, and paying national validation fees within a prescribed deadline after grant. Missing the validation deadline results in the patent having no effect in France, regardless of its validity elsewhere.
The Unitary Patent – a new instrument that came into force for participating EU member states – offers an alternative. A Unitary Patent provides uniform protection across participating states without national validation. France is a participating state. For companies that want EU-wide patent coverage without managing separate national validations, the Unitary Patent is an option worth evaluating. It is not suited to all situations: if a company's primary concern is France specifically, a direct French national patent or a validated European patent remains the standard approach.
Licensing and IP holding structures
International companies frequently hold IP rights in a parent entity or a holding company and license those rights to operating subsidiaries in France. This structure requires careful drafting. Under French tax legislation and the provisions of the Code de commerce, intra-group license agreements must reflect arm's-length terms. Transfer pricing rules apply to royalty payments between related parties. An underdocumented or below-market license can be recharacterised by French tax authorities, with additional tax and penalties.
From an IP enforcement perspective, the licensee in France must have the contractual standing to bring infringement proceedings if the parent entity is not present in France. French intellectual property legislation distinguishes between exclusive licensees – who can bring claims in their own name – and non-exclusive licensees, who generally cannot without the licensor's involvement. This distinction should be addressed in the license agreement at the drafting stage, not after infringement occurs.
Companies using a SAS structure as their French operating entity should confirm that the IP license covers the specific activities of the SAS. A license granted to a predecessor entity or a differently named legal person may not automatically extend to a restructured or renamed subsidiary. The Cour de cassation has addressed cases where a change in corporate form or a reorganisation created an inadvertent gap in licensed IP coverage.

Self-assessment checklist before acting
This checklist helps international companies determine whether their current IP position in France is adequate – and where action is most urgent.
Rights coverage:
- Have you filed national trademark applications at INPI for all brands used commercially in France, or confirmed that your EUTM provides adequate coverage and has no outstanding challenges?
- Have you validated any European patents in France within the required deadline after grant?
- Do you have registered design protection for product appearance that is commercially significant in the French market?
- Have you documented copyright ownership for works created by employees or contractors, given that French employment legislation governs copyright assignment differently from common law systems?
Maintenance and monitoring:
- Are renewal deadlines for all French registrations calendared with advance reminders at six months and three months before expiry?
- Is there documented commercial use of each registered trademark in France to defend against non-use revocation?
- Is there an active watch service monitoring INPI publications for new filings that could conflict with your marks?
Enforcement readiness:
- Does your French IP license agreement grant your local entity the standing to bring infringement proceedings independently?
- Have you identified the competent court for any infringement action you might need to bring?
- Do you have French legal counsel with IP litigation experience who can move quickly if a saisie-contrefaçon application is needed?
This approach to active IP portfolio management in France is applicable if: your company uses brand names, product names. Alternatively, technical inventions commercially in France. you have a French subsidiary. A distributor agreement. Alternatively, direct sales to French customers. and you face competitors who operate in the same product categories in French-speaking markets.
Frequently asked questions
Q: How long does a trademark application registration process at INPI typically take, and what can delay it?
A: A straightforward trademark application registration at INPI takes approximately four to six months from filing date to registration certificate, assuming no opposition is filed. Opposition proceedings add six to eighteen months depending on complexity. Formal deficiencies in the application – an unclear mark representation or an incomplete list of goods and services – can trigger a preliminary office action, adding weeks to the process. Engaging a lawyer in France with INPI filing experience reduces the risk of preventable delays.
Q: Does an EU trademark registration mean I do not need a separate French IP registration?
A: An EU trademark covers France as an EU member state and is sufficient for most commercial purposes. However, it is not identical to a French national registration. An EUTM can be invalidated across all EU member states if a challenge succeeds, leaving your French position exposed. A French national trademark survives an EU-level challenge and has its own priority date. Companies with significant French revenue or that entered the French market before expanding EU-wide often maintain both registrations as a risk management measure.
Q: What are the main costs involved in building an IP portfolio in France, and how should a company budget for it?
A: Government fees at INPI are assessed per application and per Nice classification class, starting in the hundreds of euros range for a basic single-class application. Legal fees for a law firm in France handling the filing, prior art search, and any opposition response are additional and vary by complexity. Ongoing costs include renewal fees every ten years, annual patent renewal fees, and watch service fees. Companies should also budget for enforcement costs, which – if a saisie-contrefaçon application is needed – begin in the thousands of euros range before any full infringement claim is filed.
