Intellectual property (IP) protection in France operates under a well-developed legal framework that combines national law, European Union regulations and international treaties. For international businesses, France presents both strong enforcement mechanisms and procedural nuances that can determine whether a rights holder succeeds or fails in protecting its assets. This article addresses the most frequently asked questions about IP in France, covering trademark registration, patent protection, copyright, trade secrets, enforcement tools and dispute resolution - giving business owners a practical roadmap before engaging local counsel.
France';s primary IP statute is the Code de la propriété intellectuelle (Intellectual Property Code, hereinafter the CPI), which consolidates rules on copyright, trademarks, patents, designs and related rights. The CPI is supplemented by EU Regulation 2017/1001 on the European Union Trade Mark (EUTM), EU Regulation 6/2002 on Community designs, and the European Patent Convention (EPC) administered through the European Patent Office (EPO).
The national administrative body responsible for registering trademarks, patents, designs and geographical indications is the Institut National de la Propriété Industrielle (INPI - National Institute of Industrial Property). INPI operates an online filing platform that accepts applications electronically, which significantly reduces processing time compared to paper submissions. INPI also handles opposition proceedings and certain administrative cancellation actions.
For copyright, France applies the principle of automatic protection: a work is protected from the moment of creation without any registration requirement. This derives from Article L111-1 of the CPI, which grants the author exclusive moral and economic rights over the work. Moral rights in France are perpetual, inalienable and imprescriptible - a feature that surprises many common-law practitioners accustomed to more limited author protections.
The Tribunal judiciaire de Paris (Paris Judicial Court) holds exclusive jurisdiction over most IP disputes in France, including trademark infringement, patent validity challenges and copyright claims. This specialisation means that French IP litigation is concentrated before judges with genuine technical and legal expertise in the field. The Cour d';appel de Paris (Paris Court of Appeal) hears appeals, and the Cour de cassation (Court of Cassation) reviews questions of law.
In practice, it is important to consider that EU-level rights and national French rights coexist and can be enforced simultaneously. A rights holder may rely on an EUTM to stop infringing goods entering France, while also pursuing a national trademark infringement claim before the Paris Judicial Court. Understanding which route offers faster interim relief or stronger damages is a strategic decision that should be made early.
A French national trademark is registered through INPI under the procedure set out in Articles L712-1 to L712-12 of the CPI. The applicant files an application specifying the mark, the goods or services in the relevant Nice Classification classes, and the applicant';s identity. INPI examines the application for absolute grounds of refusal - such as descriptiveness, lack of distinctiveness or deceptiveness - but does not conduct a search for conflicting earlier rights. The absence of a relative grounds examination at the filing stage is a critical procedural feature: INPI will register a mark even if an identical earlier trademark exists, leaving it to the earlier rights holder to oppose or cancel.
The opposition window opens after publication of the application in the Bulletin officiel de la propriété industrielle (BOPI - Official Gazette of Industrial Property). Third parties have two months from publication to file an opposition based on earlier rights. If no opposition is filed and no absolute grounds objection is raised, registration typically issues within three to four months of filing. The registration is valid for ten years and is renewable indefinitely upon payment of renewal fees.
A common mistake made by international applicants is relying solely on a registered EUTM without filing a national French trademark. While an EUTM covers France, enforcement before French courts sometimes benefits from a national registration, particularly when seeking customs seizure orders or when the EUTM faces a cancellation challenge in another EU member state. Maintaining a parallel national registration provides a fallback.
Non-use cancellation is a significant risk. Under Article L714-5 of the CPI, a trademark that has not been put to genuine use in France for five consecutive years without legitimate reason is vulnerable to cancellation. International businesses that register a French trademark as a defensive measure but do not actively use it in the French market should document any use carefully - including online sales directed at French consumers, French-language marketing materials and distribution agreements with French partners.
The cost of a French national trademark application at INPI starts at a low three-figure EUR amount for one class, with additional fees per class. Professional representation is not mandatory before INPI, but legal counsel is advisable to avoid classification errors that could limit the scope of protection.

A French national patent is granted by INPI under Articles L611-1 to L614-20 of the CPI. The application must disclose the invention sufficiently to allow a person skilled in the relevant field to reproduce it, and must include claims defining the scope of protection. INPI conducts a prior art search and issues a written opinion on patentability, but the grant of a French patent does not guarantee validity - courts can invalidate a patent in infringement proceedings if the defendant raises a nullity counterclaim.
Most internationally active businesses choose the European patent route via the EPO rather than a direct French national filing. A granted European patent designating France has the same legal effect as a French national patent under Article L614-7 of the CPI. The Unitary Patent, available since June 2023, provides a single patent right covering most EU member states including France, with centralised enforcement possibilities.
Patent term in France is twenty years from the filing date, subject to payment of annual maintenance fees. Supplementary protection certificates (SPCs) can extend protection for pharmaceutical and plant protection products by up to five years under EU Regulation 469/2009, which applies directly in France.
Enforcement of patent rights in France follows a two-stage approach in practice. Rights holders typically begin with a saisie-contrefaçon (infringement seizure), a uniquely French procedural tool under Article L615-5 of the CPI. A bailiff (huissier de justice), accompanied if necessary by a technical expert, enters the infringer';s premises under court authorisation to collect evidence of infringement - samples, documents, production records. The saisie-contrefaçon is obtained ex parte, meaning the infringer has no prior notice, which preserves the evidentiary value of the operation.
Following the saisie-contrefaçon, the rights holder must bring a substantive infringement action before the Paris Judicial Court within a specified period - typically within thirty working days or one month of the seizure, depending on the type of IP right. Failure to bring the action within this deadline renders the seizure null and void, destroying the evidence collected. This deadline is one of the most consequential procedural traps for foreign rights holders unfamiliar with French practice.
Patent litigation in France is technically demanding. The Paris Judicial Court has a dedicated IP chamber with judges who handle complex technical disputes. Proceedings typically last between eighteen months and three years at first instance, depending on the complexity of the technical issues and whether nullity is raised as a defence. Costs at first instance, including lawyers'; fees and technical expert fees, generally start from the mid-five-figure EUR range and can reach six figures in complex cases.
Copyright in France protects original works of authorship across a broad range of categories: literary works, musical compositions, audiovisual works, software, databases, architectural works, graphic designs and more. Originality under French law means that the work bears the imprint of the author';s personality - a standard that is somewhat broader than the purely skill-and-labour test applied in some other jurisdictions.
The duration of copyright protection is the author';s lifetime plus seventy years, in line with EU Directive 2006/116/EC. For works of joint authorship, the seventy-year period runs from the death of the last surviving co-author. Software is protected as a literary work under Article L112-2 of the CPI, but the moral rights of software authors are significantly curtailed compared to other categories: the right of integrity applies only to the extent that the modification does not harm the author';s honour or reputation.
Moral rights deserve particular attention from international businesses operating in France. Under Article L121-1 of the CPI, an author';s moral rights - including the right of disclosure, the right of attribution and the right of integrity - are perpetual and cannot be waived by contract. This means that a work-for-hire agreement governed by French law cannot strip the employee or contractor of moral rights, even if the economic rights are fully assigned to the employer. A non-obvious risk is that a French employee who created a logo or software module years ago can, in principle, object to modifications of that work on moral rights grounds even after leaving the company.
Enforcement of copyright in France uses the same saisie-contrefaçon mechanism available for patents and trademarks, adapted for copyright under Article L332-1 of the CPI. In the digital environment, rights holders can also use the notice-and-takedown procedure under the Loi pour la confiance dans l';économie numérique (Law for Confidence in the Digital Economy, LCEN), which transposes the EU E-Commerce Directive. The Autorité de régulation de la communication audiovisuelle et numérique (ARCOM - Audiovisual and Digital Communication Regulatory Authority) has powers to address online copyright infringement, particularly in the audiovisual sector.
Damages for copyright infringement in France are calculated under Article L331-1-3 of the CPI using one of three methods: actual loss suffered by the rights holder, profits made by the infringer, or a lump sum equivalent to the licence fee that would have been due. Courts increasingly award damages based on the infringer';s profits in cases of deliberate infringement, which can produce higher awards than a pure actual-loss calculation.
Trade secret protection in France was significantly strengthened by the Loi du 30 juillet 2018 relative à la protection du secret des affaires (Law of 30 July 2018 on the Protection of Trade Secrets), which transposed EU Directive 2016/943. Under this law, a trade secret is defined as information that is secret, has commercial value because it is secret, and has been subject to reasonable steps to keep it secret - all three conditions must be met simultaneously.
The definition of "reasonable steps" is where many businesses fall short. French courts examine whether the company had in place confidentiality agreements with employees and contractors, access controls on sensitive information, internal policies classifying information as confidential, and technical measures such as password protection or encryption. A company that cannot demonstrate these measures risks losing trade secret protection even for genuinely valuable information.
Remedies available under the 2018 law include injunctions, seizure of infringing goods, damages and publication of the judgment. The Paris Judicial Court handles trade secret disputes, and proceedings can be initiated urgently through the référé procedure (interim injunction procedure) when the misappropriation is ongoing or imminent. A référé order can be obtained within days or weeks, compared to the months required for a full trial on the merits.
A practical scenario: a French subsidiary of a foreign group discovers that a former senior employee has joined a competitor and appears to be using confidential pricing models and client lists. The group can immediately apply for a référé injunction before the Paris Judicial Court to prohibit the employee and the competitor from using the information, combined with a saisie-contrefaçon to preserve evidence. Simultaneously, the group should file a criminal complaint for breach of trade secrets under Article L151-1 of the CPI, which can trigger a criminal investigation and add pressure on the defendant.

French law offers rights holders a rich toolkit, but selecting the wrong tool - or applying the right tool at the wrong stage - can waste time and money while the infringement continues. The key enforcement mechanisms are: the saisie-contrefaçon, the référé injunction, the action au fond (full trial on the merits), customs seizure and criminal complaint.
The saisie-contrefaçon is the natural starting point when the rights holder needs to gather evidence before the infringer can destroy it. It is available for patents, trademarks, designs, copyright and plant variety rights. The application is made ex parte to the presiding judge of the Paris Judicial Court, and the authorisation is typically granted within one to three days. The bailiff then executes the seizure, often accompanied by a technical expert appointed by the court. The cost of a saisie-contrefaçon operation, including court fees, bailiff fees and expert fees, generally starts from the low five-figure EUR range.
Customs seizure under Articles L716-8 and L722-1 of the CPI allows rights holders to request that French customs authorities detain goods suspected of infringing trademarks, designs or copyright at the border. The rights holder files a customs application with the Direction générale des douanes et droits indirects (DGDDI - General Directorate of Customs and Indirect Taxes). Once goods are detained, the rights holder has ten working days to confirm the infringement and initiate legal proceedings, or the goods are released. EU Regulation 608/2013 provides a parallel mechanism for EU-wide customs applications.
The référé procedure before the Paris Judicial Court allows a rights holder to obtain an interim injunction stopping the infringement pending a full trial. The applicant must demonstrate urgency and a prima facie case of infringement. The court can order the infringer to cease the infringing activity, recall products from distribution channels and provide information about the supply chain. A référé order can be obtained within two to six weeks in most cases.
The action au fond is the full trial on the merits, where the court determines infringement, validity and damages definitively. This is the appropriate route when the rights holder seeks substantial damages or a permanent injunction. As noted above, first-instance proceedings typically last eighteen months to three years. The losing party generally bears a portion of the winning party';s legal costs, but French courts rarely award full cost recovery - a factor that affects the economics of litigation strategy.
Criminal complaints for IP infringement are underused by international businesses but can be highly effective. Trademark counterfeiting (contrefaçon) is a criminal offence under Article L716-9 of the CPI, carrying penalties of up to four years'; imprisonment and EUR 400,000 in fines for natural persons, with higher penalties for organised crime involvement. A criminal complaint triggers a police or gendarmerie investigation, which has coercive powers unavailable in civil proceedings - including searches, seizures and interrogations. The criminal route is particularly effective against large-scale counterfeiting operations.
Many underappreciate the importance of pre-litigation strategy in France. Sending a cease-and-desist letter (mise en demeure) before filing a saisie-contrefaçon can alert the infringer and allow evidence destruction. In cases where evidence preservation is the priority, it is often better to proceed directly to the saisie-contrefaçon without prior notice. Conversely, in cases where a negotiated settlement is the goal, a well-drafted mise en demeure can open productive discussions without the cost and delay of litigation.
A practical scenario involving a medium-sized dispute: a French distributor begins selling a foreign brand';s products outside the authorised territory, using the brand';s trademarks on its own marketing materials. The brand owner can file a trademark infringement action before the Paris Judicial Court, seek a référé injunction to stop the unauthorised use immediately, and simultaneously pursue a breach of contract claim. The combination of IP and contract claims before the same court is procedurally efficient and can produce both injunctive relief and damages.
A practical scenario involving a small dispute: a startup discovers that a competitor has copied the visual design of its website and product packaging. The startup can file a copyright infringement claim and a design infringement claim simultaneously, using the saisie-contrefaçon to preserve evidence of the copying. Even for disputes with a relatively modest value at stake, the availability of the saisie-contrefaçon makes French law a powerful tool for small rights holders who need to act quickly.

What happens if a French employee creates an invention during employment - who owns the patent?
Under Article L611-7 of the CPI, inventions made by an employee in the course of their duties, or in the field of the employer';s activities, or using the employer';s means, belong to the employer. However, the employee is entitled to additional remuneration (rémunération supplémentaire) for inventions that fall within their normal duties, and to a fair price (juste prix) for inventions outside their normal duties that the employer elects to claim. These obligations cannot be waived by contract. International businesses that acquire French companies or hire French engineers should audit existing invention assignment agreements and remuneration policies, as failure to pay the required additional remuneration can expose the employer to claims years after the invention was made.
How long does it take and how much does it cost to stop a counterfeiter in France?
Interim relief through the référé procedure can be obtained within two to six weeks of filing the application, making it one of the faster routes to stopping ongoing infringement. The saisie-contrefaçon, which precedes the substantive action, can be authorised within one to three days. Total costs for obtaining a référé injunction, including lawyers'; fees and court costs, generally start from the low five-figure EUR range. A full trial on the merits adds significantly to costs and time. The economics depend heavily on the value of the rights at stake: for high-value brands or patents, the investment in enforcement is typically justified; for lower-value rights, a negotiated settlement or a criminal complaint may offer a better cost-to-outcome ratio.
Can a foreign company enforce its IP rights in France without a French entity?
Yes. Foreign companies can bring IP infringement actions before the Paris Judicial Court directly, without needing a French subsidiary or local entity. The foreign rights holder must be represented by a French avocat (lawyer) admitted to the Paris bar for proceedings before the Paris Judicial Court. For INPI administrative proceedings such as oppositions or cancellation actions, professional representation is not mandatory but is strongly advisable given the procedural complexity. Foreign companies should also ensure that their IP rights are properly recorded - for example, that trademark licences or assignments are registered with INPI, since unregistered licences may not be enforceable against third parties under Article L714-1 of the CPI.

France offers one of the most sophisticated IP protection systems in Europe, combining strong statutory rights, specialised courts and powerful enforcement tools such as the saisie-contrefaçon. For international businesses, the key is understanding the procedural specifics - opposition deadlines, use requirements, moral rights limitations and the strategic sequencing of civil, administrative and criminal remedies - before a dispute arises. Acting without specialist knowledge of French IP procedure is a risk that can result in lost evidence, missed deadlines and unenforceable rights.
