French Intellectual Property Law: Copyright, Trade Marks, Patents, Industrial Designs, and Trade Secrets

Introduction

Intellectual property law protects creations of the mind and the commercial value that may arise from innovation, artistic expression, distinctive signs, product design, and confidential business knowledge. In France, it forms a substantial part of the legal framework governing cultural production, scientific research, technology, manufacturing, trade, publishing, and the digital economy. It gives authors and businesses legal mechanisms to control certain uses of their creations, obtain economic returns, prevent unfair appropriation, and resolve disputes over ownership and exploitation.

French intellectual property law is built around several distinct but complementary forms of protection. Copyright (droit d’auteur) protects original literary, artistic, musical, audiovisual, and other intellectual works. Trade mark law protects signs that distinguish goods and services in the marketplace. Patent law protects qualifying technical inventions. Industrial design law protects the visual appearance of products. Trade secret law protects commercially valuable information that remains confidential and is subject to reasonable secrecy measures.

These rights do not operate in the same way. Copyright arises automatically when an original work is created, without registration. Patents, trade marks, and registered designs generally require an application and registration to obtain the relevant industrial property right. Trade secrets, by contrast, depend on maintaining confidentiality and satisfying statutory conditions. Each regime has its own requirements, duration, exceptions, enforcement procedures, and relationship with European Union and international law.

The principal domestic statute is the French Intellectual Property Code (Code de la propriété intellectuelle), which brings together the rules on copyright, related rights, trade marks, patents, industrial designs, and other forms of industrial property. Trade secret protection is principally governed by provisions of the Commercial Code, introduced to implement the EU Trade Secrets Directive. French law must also be understood within the wider European framework, where EU legislation, the European Union Intellectual Property Office, the European Patent Office, and international treaties shape the protection available to creators and businesses.

This article examines the principal categories of intellectual property protection in France, the conditions under which they arise, the rights they confer, and the legal remedies available when they are infringed. It also explains how the different regimes interact in practice, particularly for businesses, authors, designers, inventors, software developers, and international operators.

1. The Legal Foundations of Intellectual Property in France

1.1 The structure of French intellectual property law

French intellectual property law is principally codified in the Code de la propriété intellectuelle (CPI). Its structure reflects the traditional distinction between two broad branches:

• Literary and artistic property (propriété littéraire et artistique), which includes copyright and related rights.
• Industrial property (propriété industrielle), which includes patents, trade marks, industrial designs, and other rights associated with technical innovation and commercial identification.

Trade secret protection occupies a related but distinct position. Its principal statutory provisions are found in the Commercial Code, rather than in the Intellectual Property Code.

The distinction is important because the legal mechanisms are different. Copyright protects an original expression without requiring a registration procedure. Industrial property rights are generally obtained through formal applications, examination, and registration or grant. Trade secret protection does not create a registered monopoly: it protects qualifying information against certain forms of unlawful acquisition, use, or disclosure while it remains secret.

These regimes may overlap. A product can, for example, embody a patented technical invention, incorporate a registered design, carry a protected trade mark, and contain software protected by copyright. Its manufacturer may also rely on trade secret law to protect confidential production methods, customer information, or technical know-how that has not been disclosed in a patent application.

Intellectual property rights are not equivalent to ownership of a physical object. Buying a painting, book, computer, or industrial product does not ordinarily transfer the copyright, patent, trade mark, or design rights associated with it. Ownership of the object and ownership of the intellectual property embodied in that object are separate legal questions.

1.2 The constitutional, European, and international context

French intellectual property law operates within a multi-level legal framework.

At national level, the Intellectual Property Code and the Commercial Code establish the principal substantive rights, procedures, limitations, and remedies. General principles of civil law, contract law, commercial law, evidence, and civil procedure also apply.

At European Union level, harmonisation has been particularly significant in trade mark law, copyright, designs, and trade secrets. EU legislation seeks to reduce differences between national systems and facilitate the circulation of goods, services, and creative works across the internal market. An EU trade mark, for example, can provide protection throughout the European Union through a single registration, while national French trade marks remain available for protection limited to France.

The European Patent Convention provides a separate framework for obtaining European patents through the European Patent Office. The European patent is not simply an EU trade mark equivalent: it is a patent granted under an international convention, which traditionally produces a bundle of national rights. The newer unitary patent system provides an additional route for participating EU Member States, subject to its territorial scope and applicable arrangements.

International conventions also influence French law. The Berne Convention protects literary and artistic works across participating states without making registration a condition of protection. The Paris Convention establishes important principles for industrial property, including national treatment and priority rights. The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) sets minimum standards for intellectual property protection among World Trade Organization members.

These instruments are particularly important where a creator, inventor, or business operates internationally. Intellectual property rights are generally territorial: protection in France does not automatically mean that identical protection exists in every other country. International conventions and regional systems make cross-border protection easier, but they do not eliminate the need to identify the relevant territories and legal mechanisms.

1.3 The role of the National Institute of Industrial Property

The National Institute of Industrial Property (Institut national de la propriété industrielle, INPI) is the central French authority for many industrial property procedures. It receives and examines French applications for patents, trade marks, and industrial designs, maintains relevant registers, and provides information and administrative services.

The INPI also contributes to the development and understanding of intellectual property protection by providing guidance to applicants, businesses, inventors, and creators. It does not, however, replace the courts. The registration of a right does not necessarily resolve every dispute about ownership, validity, infringement, contractual entitlement, or the scope of protection.

The Intellectual Property Code has also undergone procedural simplification. A decree modifying numerous provisions entered into application on 2 July 2026, including changes designed to complete the digitalisation of INPI notifications. Applicants and rights holders should therefore pay attention to electronic communications through their INPI accounts and not assume that important procedural notices will necessarily arrive by post. INPI+1

2. Copyright Law in France (Droit d’auteur)

2.1 The basic principle: protection of original expression

French copyright law protects original intellectual works. Its central principle is that protection arises from the creation of the work itself, provided that the work satisfies the legal requirement of originality. Registration is not required.

Article L111-1 of the Intellectual Property Code establishes the author’s exclusive and enforceable right in an intellectual work by the mere fact of its creation. The principle applies to literary works, musical compositions, films, photographs, paintings, sculptures, architecture, graphic works, software, and other qualifying forms of expression.

The decisive distinction is between an idea and the particular expression of that idea. Copyright does not grant ownership of general concepts, themes, methods, facts, discoveries, styles, or abstract principles. It protects the original form in which an author expresses them.

A writer cannot ordinarily prevent others from writing about the same historical event or exploring the same philosophical question. A photographer does not own the general idea of photographing a landscape. A software developer cannot claim exclusive ownership of an abstract function merely because the developer was the first to implement it. What may be protected is the original expression embodied in the text, photograph, composition, code, or other work.

Originality is assessed by reference to the author’s own intellectual creation. It is not necessarily synonymous with novelty, commercial value, artistic merit, or technical complexity. A work may be simple and still original. Conversely, an elaborate production may contain elements that are too commonplace, dictated by technical constraints, or insufficiently individualised to qualify for protection.

2.2 Categories of protected works

The Intellectual Property Code recognises a broad range of works. Article L112-2 provides an illustrative list rather than an exhaustive catalogue.

Protected subject matter includes:

• Books, articles, essays, novels, poems, and other written works.
• Lectures, speeches, and other oral works.
• Dramatic, musical, and choreographic works.
• Films and other audiovisual productions.
• Drawings, paintings, sculptures, and graphic works.
• Photographs and works produced by processes analogous to photography.
• Architectural works and plans.
• Maps, diagrams, and scientific or technical illustrations.
• Software and preparatory design materials.
• Applied art and certain forms of product-related artistic expression.

The fact that a work is published online does not remove it from copyright protection. Websites, articles, photographs, illustrations, videos, educational materials, and software may all qualify. Nor does the absence of a copyright notice mean that the work is free to reproduce.

Ideas and information may be freely discussed, subject to other applicable laws, but the particular text, image, recording, or other original expression used to communicate them may be protected.

2.3 The author and the initial ownership of copyright

The author is ordinarily the natural person who creates the work. Copyright initially belongs to that author, rather than automatically to the person who pays for the creation or provides the equipment.

This principle can create important issues in employment and commissioned work. A business that commissions a designer to create a logo, a photographer to take commercial images, or a writer to prepare an article does not necessarily acquire all copyright merely by paying the agreed fee. The parties must consider the applicable statutory rules and the contractual transfer or licensing arrangements.

French law recognises specific exceptions, particularly for certain employee-created works. Under Article L113-9, economic rights in software created by employees in the performance of their duties or following the employer’s instructions are, subject to the statutory conditions, transferred to the employer. This special rule should not be confused with a general principle that employers automatically own every copyright work produced by employees.

Collective works, collaborative works, and audiovisual works also have specific legal rules concerning authorship and the exercise of rights. A collective work may be created on the initiative and under the direction of a natural or legal person who publishes it under that person’s name, with contributions integrated into a whole. Collaborative works involve several authors contributing to a common creation. Audiovisual works have statutory rules identifying the principal categories of authors.

The distinction between authorship and ownership is especially important in commercial transactions. A person may be the author while another person or organisation lawfully holds or exercises certain economic rights under a valid transfer, statutory rule, or other legal arrangement.

2.4 Moral rights (droits moraux)

One of the distinctive characteristics of French copyright law is the strength of the author’s moral rights.

Article L121-1 of the Intellectual Property Code protects the author’s right to respect for their name, status as author, and work. The right is attached to the person of the author and is described by statute as perpetual, inalienable, and imprescriptible. It can pass to heirs upon death, and its exercise may be entrusted to a third party through testamentary arrangements. Légifrance+1

Moral rights include several important elements.

The right of attribution or authorship allows the author to insist on recognition as the creator. It protects the relationship between the author and the work, including the right to be identified by name or to use anonymity or a pseudonym.

The right to respect for the work allows the author to oppose certain distortions, alterations, or other treatment that unjustifiably harms the integrity of the work or the author’s legitimate interests.

The right of disclosure (droit de divulgation) concerns the author’s decision about when and how a work is first communicated to the public. It reflects the idea that the author has a legally protected interest in deciding when an unpublished work should be disclosed.

The right of withdrawal or reconsideration (droit de repentir ou de retrait) may permit an author, under statutory conditions, to withdraw a work from circulation or reconsider an earlier transfer of exploitation rights. Its exercise is subject to safeguards, including compensation for the prejudice suffered by the person who acquired the relevant rights.

Moral rights cannot simply be sold or permanently waived in the same manner as ordinary economic rights. A contract may regulate how a work is used and may contain permissions for adaptations or modifications, but it cannot be treated as a general elimination of the author’s statutory moral rights.

This feature distinguishes the French approach from legal systems in which moral rights are narrower or may be waived more extensively.

2.5 Economic rights (droits patrimoniaux)

Economic rights allow the author or other lawful rights holder to control the exploitation of a protected work and obtain financial benefit from it.

The principal rights include:

• Reproduction: making copies of a work, whether in print, digital, photographic, audiovisual, or other form.
• Representation or communication to the public: making a work available to the public, including through performance, broadcasting, exhibition, or online communication.
• Adaptation: authorising certain transformations or derivative uses, subject to the relevant legal rules.
• Distribution and commercial exploitation: controlling certain forms of making copies available to the public.

The distinction between reproduction and representation is important in the digital environment. Uploading a photograph to a website may involve reproduction on a server and communication to the public. Streaming music, publishing a video, distributing an ebook, and incorporating an illustration into an online course may each involve several legally distinct acts.

A licence may authorise a particular use without transferring ownership of the copyright. A publisher, broadcaster, film producer, educational platform, or software company may obtain rights for a defined purpose, territory, medium, or period. The exact scope depends on the contract and the statutory rules governing the transfer or licence.

2.6 Transfers and licensing of copyright

French law imposes formal requirements on many copyright transfers. Article L131-3 requires the rights transferred to be identified separately and the field of exploitation to be delimited as to its scope, destination, place, and duration. This approach is designed to prevent vague contractual language from being interpreted as an unlimited transfer of every possible exploitation right.

For example, an agreement authorising the publication of a novel in printed form does not automatically authorise every conceivable digital adaptation, audiovisual production, translation, or merchandising use. Those rights must be considered in the light of the agreement and the applicable law.

French law also contains rules concerning remuneration. The principle of proportional participation in the revenue generated by exploitation is important, although statutory exceptions and special arrangements exist. Lump-sum remuneration is permitted in specified circumstances, rather than being a universal substitute for the ordinary framework.

Authors and businesses should distinguish between:

1. An assignment of economic rights, under which specified rights are transferred.
2. A licence, under which the rights holder authorises defined uses while retaining ownership.
3. A publishing or production agreement, which may combine several contractual obligations with a transfer or licence of rights.
4. A commission or services agreement, which does not necessarily transfer copyright unless the required legal arrangements are made.

The practical importance is considerable. A business that wishes to reuse commissioned content in advertising, software, translations, international editions, or future products should ensure that the relevant rights have actually been acquired.

2.7 Duration of copyright protection

The general term of economic copyright protection in France is the author’s lifetime plus 70 years after death. Under Article L123-1, the period runs to the end of the calendar year in which the author dies and continues for the following 70 calendar years. For collaborative works, the relevant calculation is generally based on the death of the last surviving collaborator. Specific rules apply to anonymous, pseudonymous, collective, and certain audiovisual works. Légifrance+1

When the economic rights expire, the work generally enters the public domain and may be used without the former economic monopoly, subject to other applicable rights and restrictions. The author’s moral rights, however, do not expire in the same way. The public-domain status of a work therefore does not mean that every alteration, false attribution, or misleading presentation is necessarily lawful.

2.8 Exceptions and limitations

Copyright is not absolute. French law recognises statutory exceptions intended to reconcile the author’s rights with other interests, including private use, education, research, criticism, information, freedom of expression, and cultural access.

Important exceptions include:

• Private copying, subject to the applicable conditions and limitations.
• Certain private and free performances within the family circle.
• Short quotations justified by the critical, polemical, educational, scientific, or informational purpose of the work in which they are incorporated.
• Parody, pastiche, and caricature, subject to the legal requirements.
• Certain uses for teaching and research.
• Certain preservation and consultation activities carried out by libraries, museums, and archival institutions.
• Specific exceptions relating to accessibility and other statutory public-interest purposes.

These exceptions are interpreted within their legal limits. A quotation is not lawful simply because the user attributes the source. The quotation must satisfy the relevant requirements, including its purpose and proportionality. Similarly, an educational use is not automatically exempt merely because it takes place in a school, university, or online course.

The French Ministry of Economy’s guidance emphasises that exceptions must be assessed carefully and that moral rights remain relevant even where an economic-rights exception applies. economie.gouv.fr+1

2.9 Related rights

Copyright must be distinguished from related rights (droits voisins). These protect certain persons and organisations involved in the communication, performance, production, and dissemination of works.

Related-rights holders include performers, phonogram producers, audiovisual producers, and broadcasting organisations. A singer may have rights as a performer in addition to the author’s rights held by the composer and lyricist. A film may involve authors’ rights in the screenplay and direction, performers’ rights, and the producer’s related rights.

This layered structure explains why the lawful use of music, films, recordings, and other audiovisual content may require several permissions. Obtaining permission from one rights holder does not necessarily clear all the rights involved.

2.10 Copyright and digital content, software, and artificial intelligence

Digital technology has expanded the practical importance of copyright. Online publication, streaming, social media, digital libraries, software distribution, and artificial intelligence systems raise questions about reproduction, communication to the public, licensing, authorship, and exceptions.

Software is protected by copyright as a form of intellectual work, although the protection does not extend to abstract ideas, algorithms as such, or technical principles merely because they are implemented in code. Software licensing also involves contractual rules, and open-source software remains subject to the conditions of the applicable licence.

Artificial intelligence creates more complex questions. French copyright law continues to require a protected work and the relevant legal conditions of authorship and originality. A person who uses an AI system does not automatically acquire copyright in every output simply because they supplied a prompt. The question is whether the claimed work contains protectable human intellectual creation and whether the claimant can establish the necessary authorship and rights. Training uses, reproduction of protected material, and outputs that reproduce protected expression raise separate questions under French and EU law. These matters must be assessed under the applicable legislation and case law rather than by assuming that all AI-generated material is either automatically protected or automatically free of copyright constraints.

3. Trade Mark Law in France (Droit des marques)

3.1 Purpose and function of a trade mark

A trade mark is a sign used to distinguish the goods or services of one undertaking from those of other undertakings. Its central function is to identify commercial origin and enable consumers to recognise and distinguish products and services in the marketplace.

Trade marks also perform economic and reputational functions. They help businesses develop brand identity, maintain consumer confidence, differentiate products, and protect investments in marketing and commercial goodwill. For consumers, they can provide information about the source of goods and services, although a trade mark does not itself guarantee product quality.

French trade mark law is contained principally in the Intellectual Property Code, particularly the provisions governing the definition, registration, scope, and enforcement of trade marks. It is also substantially harmonised by EU legislation, especially Regulation (EU) 2017/1001 on the European Union trade mark and Directive (EU) 2015/2436 approximating the laws of Member States relating to trade marks.

3.2 What can be registered as a trade mark?

A sign may qualify as a trade mark if it is capable of distinguishing the goods or services of one undertaking from those of another and can be represented in the register in a manner that enables the competent authorities and the public to determine clearly and precisely what is protected.

Depending on the circumstances, registrable signs may include:

• Words, names, and combinations of letters.
• Slogans and expressions.
• Logos and figurative devices.
• Numbers and letters.
• Three-dimensional shapes.
• Colours or combinations of colours.
• Sounds.
• Certain forms of movement or multimedia signs.

The modern legal framework is not restricted to traditional word marks and graphic logos. Nevertheless, the sign must satisfy the legal requirements and must be represented with sufficient clarity in the application.

A company name, domain name, shop sign, or product label may have commercial importance without automatically being a registered trade mark. These forms of identification may receive protection under other legal rules, but their existence does not necessarily establish the same exclusive rights as a registered mark.

3.3 Conditions for registration

A trade mark must satisfy several substantive conditions.

Distinctiveness is fundamental. The sign must be capable of identifying the commercial origin of the relevant goods or services. A purely descriptive expression that simply identifies the nature, quality, purpose, or characteristics of the goods may be refused because competitors must remain free to use ordinary descriptive language.

Lawfulness and public policy also matter. A sign may be refused if it conflicts with applicable legal requirements, public policy, or accepted principles of morality.

Non-deceptiveness is required. A mark must not mislead the public, particularly as to the nature, quality, or geographical origin of goods or services.

Availability must also be considered. A sign may conflict with an earlier trade mark or another protected right. The applicant should therefore examine existing registrations and relevant earlier rights before filing.

A sign may be inherently distinctive for one category of goods but descriptive for another. The assessment is therefore made in relation to the goods and services specified in the application, not in the abstract.

3.4 Filing and registration through the INPI

A French national trade mark application is filed with the INPI. The applicant must identify the sign and specify the goods and services for which protection is requested. Those goods and services are classified under the Nice Classification, an international system used to organise products and services into classes.

The applicant should select the classes carefully. A registration does not grant an unlimited monopoly over a word or logo in every commercial context. The scope of protection is linked to the registered sign and the goods and services covered, subject to rules on similarity, reputation, and other relevant circumstances.

Following filing, the INPI examines the application and publishes it. Third parties may oppose registration on the basis of specified earlier rights. The INPI may also raise objections where the application fails to satisfy applicable legal requirements.

The opposition procedure is particularly important for existing rights holders. According to the INPI, opposition to a French trade mark application must generally be filed within two months of publication of the application. The procedure is conducted online and allows the parties to exchange written arguments. INPI+1

Registration should not be treated as a guarantee that no conflict exists. Some disputes emerge only after the mark is used commercially, and certain earlier rights may not be identified through a basic register search.

3.5 Scope of trade mark rights

The owner of a registered trade mark may generally prevent unauthorised third-party use of an identical or similar sign in commercial activities where the legal conditions for infringement are satisfied.

The strongest protection applies where an identical sign is used for identical goods or services. Protection may also extend to similar signs and goods or services where there is a likelihood of confusion, including a likelihood that consumers may believe that the products or services come from the same undertaking or economically linked undertakings.

Marks with a reputation may benefit from broader protection in certain circumstances, including against uses that take unfair advantage of, or cause detriment to, the distinctive character or reputation of the mark, even where the goods or services are not similar.

The assessment of infringement is contextual. Courts may consider the visual, phonetic, and conceptual similarities between signs, the nature of the goods or services, the relevant public, and the overall likelihood of confusion. A minor difference in spelling or graphic presentation does not necessarily prevent infringement.

3.6 Duration, renewal, and genuine use

A French trade mark registration lasts for ten years from the filing date and may be renewed indefinitely for successive ten-year periods. Renewal is not automatic: the owner must complete the prescribed procedure and pay the required fee.

The INPI states that renewal should ordinarily be requested during the year preceding expiry, with a further six-month grace period available after the expiry date subject to the applicable additional fee. INPI+1

Registration alone is not always sufficient to preserve a mark indefinitely. A trade mark may be vulnerable to revocation if it has not been put to genuine use in connection with the goods or services for which it is registered during the relevant continuous five-year period, unless proper reasons for non-use exist.

This rule prevents businesses from accumulating registrations for signs that they do not genuinely use while blocking competitors from adopting commercially legitimate names. Genuine use must be assessed in relation to the market and the relevant goods or services.

3.7 Trade mark transfers, licences, and coexistence

A trade mark is an intangible asset that may be transferred, licensed, inherited, or used as part of a wider commercial transaction. It may be included in the sale of a business, transferred separately, or licensed to another undertaking.

A licence may be exclusive or non-exclusive and may define territories, products, quality standards, duration, royalties, and conditions of use. A trade mark licence is particularly important in franchising, distribution, merchandising, and brand partnerships.

The parties should address quality control, authorised forms of use, responsibility for enforcement, and the treatment of improvements or variations. A poorly drafted licence can create uncertainty about who may take action against infringers and who bears the commercial consequences of misuse.

Coexistence agreements may also be used where businesses agree to operate with similar marks under defined conditions. Such agreements cannot override mandatory law or necessarily eliminate the rights of third parties, and their effectiveness depends on the circumstances.

3.8 French and European Union trade marks

Businesses operating beyond France may choose between a national French registration and an EU trade mark.

A French registration provides protection in France. An EU trade mark application filed with the European Union Intellectual Property Office (EUIPO) can provide unitary protection throughout the EU, subject to the rules governing registration, opposition, use, and invalidity.

The EU system is not simply a collection of separate national registrations. It creates a unitary right, meaning that certain decisions concerning validity or infringement may have effects across the EU territory. This can be advantageous for businesses with a genuinely European market, but it also means that an obstacle in one Member State may affect the application or validity of the EU trade mark more broadly.

International protection may also be sought through the Madrid System administered by the World Intellectual Property Organization (WIPO), which allows applicants to seek protection in designated territories through an international registration based on an appropriate basic application or registration.

4. Patent Law in France (Droit des brevets)

4.1 The purpose of patent protection

Patent law protects qualifying technical inventions. It is intended to encourage innovation by giving inventors a temporary exclusive right in exchange for public disclosure of the invention.

The patent system therefore involves a legal and economic exchange. The inventor discloses technical information in a patent application, allowing the invention to become part of the public technical record. In return, the patent holder obtains an exclusive right to prevent certain unauthorised commercial acts for a limited period.

A patent is not a general reward for creativity or commercial success. It protects a defined technical invention that satisfies statutory requirements. Nor does obtaining a patent automatically mean that the patent holder is free to manufacture or sell the invention: other patents, regulatory restrictions, safety requirements, and third-party rights may still apply.

4.2 Conditions of patentability

Under French law, an invention must generally satisfy three principal requirements: novelty, inventive step, and industrial applicability.

Novelty means that the invention must not form part of the state of the art before the relevant filing or priority date. The state of the art includes information made available to the public anywhere in the world through written or oral description, use, or any other means.

Public disclosure before filing can therefore be extremely damaging. An inventor who publishes technical details in a journal, presents them at a conference, places a product on the market, or describes the invention publicly before filing may destroy novelty. Limited statutory exceptions may apply in particular circumstances, but they should not be relied upon as a substitute for filing strategy.

Inventive step requires that the invention is not obvious to a person skilled in the relevant technical field, having regard to the state of the art. A minor or routine modification of an existing product may fail this requirement even if it is technically new in a narrow sense.

Industrial applicability means that the invention must be capable of being made or used in some kind of industry, including agriculture. The concept is broad but excludes subject matter that does not meet the statutory requirement.

The INPI identifies these three conditions as essential requirements for patentability. INPI+1

4.3 Excluded subject matter

Not every discovery, idea, or technical proposal can be patented.

French law excludes certain categories from patentability, including discoveries, scientific theories, mathematical methods, aesthetic creations, schemes and methods for performing mental acts, playing games, or doing business, and computer programs as such.

Methods of medical treatment of the human or animal body by surgery or therapy, and diagnostic methods practised on the human or animal body, are also subject to statutory exclusions, although products, substances, and compositions for use in such methods may be patentable where the legal conditions are met.

Inventions contrary to public policy or morality may be excluded. Certain biological subject matter is also subject to specific limitations.

The exclusion of computer programs as such does not mean that all inventions involving software are unpatentable. A computer-implemented invention may be patentable where it produces a technical contribution and satisfies the ordinary requirements. A mere abstract algorithm or business method implemented on a computer is not enough.

4.4 Filing a patent application

A French patent application is filed with the INPI. The application must identify the invention and contain a description sufficiently clear and complete to enable a person skilled in the relevant field to carry it out.

The application generally includes:

• A description of the invention.
• One or more claims defining the protection sought.
• Drawings where necessary.
• An abstract.
• The relevant applicant and inventor information.

The claims are particularly important because they define the legal scope of the patent. The description explains the invention and supports the claims, but the patent’s enforceable boundaries cannot be determined simply by looking at the commercial product or the general idea behind it.

The patent application is examined under the applicable statutory framework. The INPI conducts the relevant searches and examination procedures and may raise objections. The applicant may have to amend claims or respond to observations before grant.

Patent applications are generally published after the prescribed period, commonly 18 months from the filing or priority date. Publication makes the technical disclosure accessible to the public, even though the final scope and status of the application may still be subject to further proceedings.

4.5 Ownership of inventions and employee inventions

Ownership is a central issue in patent law, particularly where inventions arise in employment, research institutions, universities, or collaborative commercial projects.

French law contains a specific regime for employee inventions under Article L611-7 of the Intellectual Property Code. The legal treatment depends on the circumstances in which the invention was made.

Mission inventions are inventions made by an employee in the performance of an inventive mission corresponding to the employee’s actual duties, or in the context of studies or research expressly entrusted to the employee. These generally belong to the employer, subject to the employee’s right to additional remuneration under the applicable rules.

Non-mission inventions that are attributable to the employer may arise outside the employee’s assigned inventive duties but through the use of the employer’s resources, knowledge, or activities in circumstances defined by law. The employer may have a statutory right to claim ownership or certain rights, subject to the relevant conditions and financial consequences.

Non-attributable inventions generally belong to the employee where they do not fall within the preceding categories.

The classification is fact-sensitive. Employment contracts, job descriptions, research instructions, laboratory access, use of company resources, and the relationship between the invention and the employer’s activities may all be relevant. A contract cannot simply ignore the statutory employee-invention framework.

4.6 Scope and duration of patent rights

A patent gives its owner the right to prevent certain unauthorised acts involving the patented invention. Depending on whether the patent concerns a product or a process, prohibited acts may include making, offering, placing on the market, using, importing, or possessing a patented product for those purposes. For process patents, protection may also extend to the use of the process and certain products obtained directly through it.

The rights are limited by the claims, statutory exceptions, and the territorial scope of the patent.

A French patent generally lasts for 20 years from the filing date, provided that the required renewal fees are paid. It cannot ordinarily be renewed indefinitely. Certain pharmaceutical and plant-protection products may qualify for supplementary protection certificates, which provide additional protection under a separate legal regime to compensate, within defined limits, for time lost through regulatory authorisation procedures. Direction générale des Entreprises+1

4.7 Exceptions and limitations to patent rights

Patent rights are subject to statutory limitations. These may include certain private and non-commercial acts, experimental acts relating to the subject matter of the patented invention, specified activities involving medicines prepared in pharmacies under the relevant conditions, and other legally defined exceptions.

The experimental-use exception is particularly important in research and development. It does not mean that every commercial activity described as research is automatically exempt. The nature and purpose of the activity, the statutory wording, and the relevant circumstances must be examined.

Compulsory licences and other mechanisms may also apply in defined situations. They reflect the principle that patent rights, although exclusive, are not necessarily absolute where public interest and statutory conditions justify intervention.

4.8 Patent infringement and remedies

Patent infringement (contrefaçon) occurs where a person carries out an act prohibited by the patent rights without the required authorisation and without benefiting from an applicable exception or defence.

A patent owner may seek judicial relief, including:

• An injunction prohibiting continued infringement.
• Damages for the harm suffered.
• Measures concerning infringing products and materials.
• Publication of the judgment in appropriate circumstances.
• Evidential measures to establish the infringement.

French law provides a procedure known as saisie-contrefaçon, which can allow a rights holder, subject to judicial authorisation and procedural safeguards, to obtain evidence of alleged infringement. It can be a powerful mechanism in technical disputes, but it must be used within the statutory framework.

Patent infringement litigation is centralised in specialised judicial courts. Article L615-17 of the Intellectual Property Code provides for exclusive jurisdiction in specified judicial courts for civil actions and claims relating to patents, subject to the statutory exception for certain challenges to administrative acts. The Paris Judicial Court has a central role in patent litigation. Légifrance+1

A patent may also be challenged on validity grounds. Infringement proceedings can therefore involve complex questions about claim interpretation, novelty, inventive step, disclosure, ownership, and the technical evidence needed to establish infringement.

4.9 French, European, and unitary patent protection

An inventor seeking protection beyond France has several possible routes.

A French national patent provides protection in France. A European patent application filed under the European Patent Convention is examined by the European Patent Office. Once granted, the traditional European patent generally takes effect as a bundle of national rights in the states where the relevant requirements are fulfilled.

The unitary patent system adds a further option for participating EU Member States. A European patent may be given unitary effect, subject to the applicable conditions and territorial participation. The Unified Patent Court provides a common judicial framework for participating states and has jurisdiction over relevant disputes within its competence.

The European patent system and the EU unitary patent system should not be confused. The European Patent Convention is not an EU instrument, and not every European Patent Convention member is an EU Member State. A European patent may therefore cover territories outside the EU, while unitary effect applies only within the participating EU framework.

For businesses, the appropriate route depends on markets, costs, enforcement strategy, the nature of the invention, and the territories in which protection is commercially necessary.

5. Industrial Designs (Dessins et modèles)

5.1 What industrial design law protects

Industrial design law protects the visual appearance of a product, rather than its technical function. The appearance may result from the product’s lines, contours, colours, shape, texture, materials, ornamentation, or combination of visual features.

The subject matter can include furniture, clothing, packaging, household products, industrial equipment, digital icons, graphic symbols, and many other forms of product appearance. Protection may relate to the whole product or only to a part of it.

The distinction between design protection and patent protection is important. A patent protects a qualifying technical invention. A registered design protects the appearance of a product. A chair’s original mechanical adjustment system might be protected by a patent, while its distinctive external shape might be protected as a design.

5.2 Conditions for design protection

A registered design must generally be new and possess individual character.

A design is new if no identical design has been made available to the public before the relevant date, subject to the applicable statutory rules and disclosure exceptions.

Individual character means that the overall impression produced on the informed user must differ from the overall impression produced by earlier designs. The assessment takes account of the designer’s degree of freedom in developing the design. Where technical constraints leave little freedom, relatively small differences may carry greater significance than they would in a field where designers enjoy considerable freedom.

Design law does not protect features of appearance that are solely dictated by technical function. It also contains specific rules concerning features that must be reproduced in their exact form and dimensions to permit the product to be mechanically connected to or placed in, around, or against another product, subject to statutory exceptions.

5.3 Registration and duration

A French design application is filed with the INPI. The applicant must provide representations of the design that clearly identify the appearance for which protection is sought. The quality and consistency of these representations are important because they help determine the scope of the right.

A registered French design is protected for an initial period of five years. It may be renewed in successive five-year periods up to a maximum total term of 25 years, subject to the required formalities and fees. Insee+1

A design registration does not necessarily protect every feature of a product. Its scope depends on the design as represented and the applicable legal rules. Businesses should therefore consider carefully whether they need to register the whole product, selected components, variations, or a collection of related designs.

5.4 Unregistered design protection and copyright overlap

French and EU law also recognise certain forms of unregistered design protection, although their conditions and duration differ from registered design rights.

At EU level, an unregistered Community design generally provides protection for three years from the date on which the design was first made available to the public within the European Union. It principally protects against deliberate copying rather than every independent creation of a similar design.

A product’s appearance may also qualify for copyright protection if it satisfies the originality requirement. The two systems protect different legal interests and apply different tests. A design may therefore benefit from both copyright and design protection, although the existence and scope of each right must be assessed independently.

This overlap can be particularly relevant to fashion, furniture, industrial design, graphic creation, and applied art. It should not be assumed that every commercially attractive product shape is automatically protected by copyright.

5.5 Design infringement and enforcement

The owner of a registered design may prevent unauthorised commercial use of a design that does not produce a different overall impression on the informed user, within the scope of the relevant right and subject to statutory limitations.

Infringing conduct may include manufacturing, offering, marketing, importing, exporting, or using products incorporating the protected design, depending on the applicable legal rules.

The rights holder may seek injunctions, damages, evidential measures, and other remedies available under the Intellectual Property Code. As with other intellectual property rights, enforcement requires evidence of ownership, the protected subject matter, the alleged infringing acts, and the relevant territorial and temporal scope.

6. Trade Secrets (Secret des affaires)

6.1 The nature and purpose of trade secret protection

Trade secret protection is different from copyright, trade mark, patent, and design protection. It does not depend on a formal registration or grant by a public authority. Instead, it protects certain commercially valuable information against unlawful acquisition, use, or disclosure, provided that the information satisfies the statutory requirements and the holder has taken reasonable steps to preserve its secrecy.

In France, the principal rules are contained in Articles L151-1 and following of the Commercial Code. They were introduced by Law No. 2018-670 of 30 July 2018, implementing Directive (EU) 2016/943 on the protection of undisclosed know-how and business information against their unlawful acquisition, use, and disclosure.

Trade secrets may include manufacturing processes, formulas, technical specifications, research results, source code, algorithms, business strategies, pricing models, supplier information, customer databases, marketing plans, and other confidential commercial or technical knowledge.

Not every piece of confidential information is a trade secret in the statutory sense. The legal requirements are specific and cumulative.

6.2 The three statutory conditions

Article L151-1 of the Commercial Code provides that information qualifies for protection as a trade secret where three conditions are satisfied:

1. It is not generally known or readily accessible to persons familiar with the type of information in the relevant field, either in itself or in the precise configuration and arrangement of its elements.
2. It has actual or potential commercial value because it is secret.
3. Its lawful holder has taken reasonable measures, having regard to the circumstances, to preserve its secrecy. Légifrance+1

These conditions distinguish legally protected trade secrets from information that a business merely prefers not to disclose.

Secrecy does not require that only one person know the information. Employees, contractors, advisers, suppliers, or business partners may have authorised access without destroying protection, provided that access is controlled and the information is not generally known or readily accessible.

Commercial value may be actual or potential. A confidential manufacturing technique may reduce production costs. A customer database may provide a competitive advantage. Research findings may save a competitor years of development. The information need not already generate revenue, but its secrecy must have commercial significance.

Reasonable protective measures are essential. The holder should be able to demonstrate that it took appropriate steps to preserve confidentiality. The level of protection expected depends on the nature of the information, the size of the organisation, the commercial context, and the risks involved.

6.3 Reasonable measures to preserve secrecy

Businesses should treat trade secret protection as an organisational and contractual responsibility, rather than relying solely on the statutory definition.

Reasonable measures may include:

• Confidentiality agreements with employees, consultants, suppliers, and commercial partners.
• Access restrictions based on professional need.
• Password protection, encryption, and secure storage.
• Internal classification of confidential information.
• Employee training and confidentiality policies.
• Secure procedures for transferring documents and technical data.
• Restrictions on copying, downloading, and external disclosure.
• Exit procedures for employees and contractors who have had access to sensitive information.
• Clear contractual arrangements for research, development, outsourcing, and joint ventures.

The law does not prescribe one universal security system. A small business may reasonably use measures different from those expected of a large pharmaceutical company or technology enterprise. The important question is whether the measures are reasonable in the circumstances and whether they demonstrate a genuine effort to maintain secrecy.

A business that leaves commercially valuable information freely accessible to the public, distributes it without restrictions, or fails to control access may find it difficult to establish the statutory conditions.

6.4 Unlawful acquisition, use, and disclosure

Trade secret protection is directed against unlawful conduct, not against every form of competition or independent discovery.

Unlawful acquisition may occur through unauthorised access, appropriation, copying, or other conduct contrary to honest commercial practices. It may also arise where a person obtains information through a breach of a confidentiality obligation or another duty restricting its use or disclosure.

Unlawful use or disclosure may occur where a person has acquired a trade secret unlawfully or uses or discloses it in breach of a contractual or other duty not to do so. A person may also incur liability where they knew, or in the circumstances ought to have known, that the information originated from an unlawful act.

The rules can apply to persons and businesses further down a commercial chain. A competitor that receives information from a third party may face liability if the statutory knowledge requirements are satisfied, even if it did not personally steal the information.

6.5 Lawful acquisition and the limits of protection

Trade secret law does not create a monopoly over information in the same way as patent law. Certain forms of acquisition and use remain lawful.

Independent discovery or creation is generally lawful. A competitor may develop the same manufacturing method through its own research, provided that it does not unlawfully obtain or use another business’s protected information.

Observation, study, disassembly, or testing of a product that has been made available to the public or is lawfully possessed may also be lawful in circumstances recognised by the statute, provided that the person acquiring the information is not subject to a valid duty restricting such acquisition.

This is important for reverse engineering. Trade secret protection does not automatically prevent a competitor from examining a lawfully acquired product and discovering how it works. Contractual restrictions, other intellectual property rights, regulatory rules, and the circumstances of acquisition may nevertheless affect the analysis.

The distinction between unlawful appropriation and legitimate competition is fundamental. Trade secret law protects confidential commercial knowledge against dishonest acquisition and misuse; it does not grant an exclusive right over information that others independently develop or lawfully discover.

6.6 Exceptions and protected disclosures

Trade secret protection is subject to important exceptions designed to preserve freedom of expression, information, public-interest reporting, and lawful conduct.

Article L151-8 of the Commercial Code provides, among other things, that trade secret protection cannot be invoked in certain circumstances involving freedom of expression and communication, including press freedom, or the disclosure in good faith of unlawful activity, misconduct, or wrongdoing in order to protect the general interest. The statutory framework also addresses the exercise of employee and whistleblower rights. Légifrance+1

The protection of trade secrets must therefore be balanced against other legally recognised interests. An employer cannot assume that every disclosure of internal information is unlawful simply because the information has been labelled confidential. Equally, the existence of a public-interest exception does not create a general right to disclose any confidential business information for any purpose.

The circumstances, the purpose of disclosure, the good faith of the person concerned, and the relevant statutory conditions are all significant.

6.7 Remedies for trade secret misappropriation

The lawful holder of a trade secret may seek judicial measures against unlawful acquisition, use, or disclosure.

Depending on the circumstances, remedies may include:

• Prohibitions on continued or threatened unlawful use or disclosure.
• Measures to prevent infringing goods from being produced, offered, placed on the market, imported, or exported.
• Withdrawal or destruction of certain infringing materials or goods.
• Damages reflecting the harm caused by the unlawful conduct.
• Measures to preserve confidentiality during litigation.

The courts must take account of the need to protect the trade secret during proceedings. A claim about confidential information can create a practical difficulty: the claimant may need to prove the existence and misuse of the information without making it public through the litigation itself. French procedural rules therefore provide mechanisms intended to protect confidential material in appropriate circumstances.

Trade secret protection is particularly useful where disclosure through a patent application would be commercially undesirable or where the information is not patentable. However, it is inherently more fragile than a registered exclusive right. Once information becomes generally available, its secrecy-based protection may be lost.

7. Other Forms of Intellectual Property and Related Protection

The principal rights considered above do not exhaust the forms of protection available under French law. Businesses and creators may also rely on several additional mechanisms.

7.1 Geographical indications

Geographical indications identify products whose qualities, reputation, or characteristics are linked to a particular geographical origin. They protect the connection between a product and the place with which it is associated.

French law has a long tradition of geographical-origin protection, especially in relation to agricultural products, foodstuffs, wines, and spirits. The European Union has developed extensive systems of protected designations of origin and protected geographical indications.

French law also provides for geographical indications protecting certain industrial and artisanal products. The INPI is responsible for homologating these indications within its statutory remit, while agricultural and food-related systems operate under their own national and EU frameworks. Direction générale des Entreprises+1

Geographical indications are not simply private brands. They protect a collective connection between a product, a defined geographical area, and specified production or quality characteristics. Their use is governed by product specifications and the relevant legal conditions.

7.2 Plant variety rights

Plant variety rights protect qualifying new plant varieties. In France, this field is governed by specific legislation and operates alongside the EU Community plant variety rights system administered by the Community Plant Variety Office.

The protection is distinct from ordinary patent protection because it is adapted to the biological and agricultural characteristics of plant varieties. Applicants must satisfy the relevant criteria, including distinctness, uniformity, stability, and novelty under the applicable system.

7.3 Semiconductor topographies

The Intellectual Property Code also provides protection for certain original topographies of semiconductor products. This protection concerns the three-dimensional arrangement of elements and interconnections in integrated circuits, rather than the abstract function of the circuit.

It reflects the specialised nature of semiconductor design and the economic importance of protecting the investment involved in developing complex integrated circuit layouts.

7.4 Domain names, company names, and unfair competition

A domain name, company name, trade name, or commercial sign may be protected through legal mechanisms other than trade mark registration.

For example, the unauthorised use of a business identifier may, depending on the circumstances, constitute infringement of an earlier trade mark, an act of unfair competition, or a form of parasitic conduct under general civil liability principles.

French courts may apply Articles 1240 and 1241 of the Civil Code where a claimant establishes fault, damage, and a causal link. These provisions do not create a substitute trade mark registration system. Rather, they may address wrongful conduct that causes harm beyond, or independently of, the infringement of a registered intellectual property right.

8. Ownership, Contracts, and Commercial Exploitation of Intellectual Property

8.1 Intellectual property as a business asset

Intellectual property rights can be among the most valuable assets of a business. A company’s value may depend heavily on its software, trade marks, patents, product designs, copyright portfolio, technical know-how, or confidential customer information.

These assets may be exploited directly or through licensing, assignment, franchising, distribution, research partnerships, technology transfer, or other commercial arrangements.

For this reason, businesses should identify and document the intellectual property they own or use. A company that cannot establish ownership of the software, logo, website content, product design, or technical invention on which its business depends may face difficulties when seeking investment, selling the business, entering commercial partnerships, or enforcing its rights.

8.2 Assignment and licensing

An assignment transfers ownership of specified intellectual property rights. A licence authorises another person to use rights under defined conditions while ownership remains with the rights holder.

The legal requirements differ according to the type of right. Copyright transfers are subject to specific formal requirements. Trade mark, patent, and design assignments and licences must comply with the relevant provisions of the Intellectual Property Code and may be recorded in the appropriate registers to ensure their effectiveness against third parties under the applicable rules.

A well-drafted agreement should identify:

• The rights covered by the transaction.
• The territory in which the rights may be exercised.
• The duration of the assignment or licence.
• The permitted uses and commercial activities.
• Whether the licence is exclusive or non-exclusive.
• The remuneration, royalties, or other financial arrangements.
• The rights and responsibilities of the parties in relation to enforcement.
• Confidentiality and security obligations.
• The consequences of termination and any continuing rights.

The scope of the agreement should be clear. A general reference to ownership of a project or delivery of a product does not necessarily settle every intellectual property question.

8.3 Intellectual property in employment and commissioned work

Employment and commissioned-work arrangements create recurring disputes about ownership.

A company may pay an employee to develop a product, a freelancer to design a website, or a consultant to create technical documentation. The fact that the company paid for the work does not necessarily establish that it owns all resulting intellectual property.

The parties should identify the relevant rights at the beginning of the relationship. For inventions, the statutory employee-invention regime must be considered. For software, the special statutory rule on employee-created software may apply. For other copyright works, the ordinary authorship and transfer rules are relevant.

Businesses should also consider the position of subcontractors, temporary workers, external designers, and independent developers. A company may receive deliverables from a contractor without obtaining every intellectual property right necessary to use, modify, distribute, or commercialise them.

8.4 Due diligence and intellectual property portfolios

Intellectual property due diligence is particularly important in mergers, acquisitions, investment transactions, and technology partnerships.

A review may examine:

• Whether registrations are valid and current.
• Whether renewal fees have been paid.
• Whether the correct person or entity owns the rights.
• Whether employee and contractor assignments are effective.
• Whether third-party licences restrict commercial use.
• Whether open-source software obligations have been respected.
• Whether trade secrets are adequately protected.
• Whether infringement disputes or threats exist.
• Whether the business has freedom to operate in the relevant markets.

A registration certificate is only one part of the picture. The practical value of an intellectual property portfolio depends on the scope, validity, ownership, enforceability, and commercial usefulness of the rights.

9. Intellectual Property Infringement and Enforcement in France

9.1 The concept of infringement

The French term contrefaçon is used for infringement of several intellectual property rights. Its precise legal meaning depends on the right involved.

Copyright infringement may result from unauthorised reproduction, representation, adaptation, or other exploitation of a protected work. Trade mark infringement may involve unauthorised use of an identical or similar sign in circumstances prohibited by trade mark law. Patent infringement concerns acts falling within the exclusive rights conferred by a valid patent. Design infringement involves unauthorised use of a protected design within the relevant legal scope.

The claimant must establish the existence and ownership of the right, the protected subject matter, the relevant acts, and the absence of an applicable authorisation or exception. The details differ significantly between the regimes.

9.2 Civil remedies

Civil enforcement is central to intellectual property protection. A rights holder may seek an injunction to stop unlawful conduct, damages to compensate for harm, and other measures provided by the applicable legislation.

Damages may take account of relevant factors such as the negative economic consequences of infringement, lost profits, the profits made by the infringer, and non-economic harm where recognised by the applicable rules. In certain circumstances, the court may consider a lump-sum method of assessing damages under the Intellectual Property Code.

Injunctions can be especially important where continued infringement would undermine the commercial value of the right. A court may also order measures concerning infringing goods, including withdrawal from commercial channels or destruction, where the statutory conditions are met.

9.3 Evidential measures and saisie-contrefaçon

Intellectual property disputes can be difficult to prove. Infringing products may be concealed, online activity may be rapidly altered, and technical information may be held exclusively by the alleged infringer.

French law provides for saisie-contrefaçon, a specialised evidential procedure that can enable a rights holder to obtain evidence of alleged infringement. Depending on the circumstances and the relevant statutory provisions, the measure may involve a detailed description, physical seizure, or collection of documents and information.

It is not a general investigative power. It requires compliance with procedural safeguards and the relevant authorisation requirements. A claimant must also respect the limits of the order and the rights of the person against whom the measure is directed.

9.4 Criminal liability

Certain intellectual property infringements may also constitute criminal offences. The Intellectual Property Code provides criminal penalties for specified acts of infringement, including forms of copyright and industrial property counterfeiting.

Criminal enforcement may be particularly relevant where infringement is organised, commercial in scale, or associated with the production and distribution of counterfeit goods. Customs authorities also play an important role in identifying and detaining suspected counterfeit products at the border under the relevant national and EU procedures.

The existence of criminal provisions does not mean that every intellectual property dispute is criminal. Many disputes concern ownership, licensing, contractual interpretation, scope of protection, or the validity of a right and are resolved through civil proceedings.

9.5 Limitation periods and jurisdiction

Limitation periods vary according to the legal action and the right concerned. For patent infringement, Article L615-8 of the Intellectual Property Code provides a five-year limitation period running from the day on which the rights holder knew or ought to have known the last fact enabling the action to be exercised. Légifrance+1

Jurisdiction is also specialised in several areas. Patent litigation is centralised in designated judicial courts, with the Paris Judicial Court playing a central role. Appeals against certain INPI decisions are assigned to the competent courts under the applicable procedural rules. Trade mark, design, and copyright disputes are also subject to specialised jurisdictional provisions.

The distinction between judicial and administrative jurisdiction remains relevant. The INPI performs administrative functions in registration and opposition procedures, while courts determine civil claims and other disputes within their statutory jurisdiction. A challenge to an administrative decision is not necessarily the same as an infringement action between private parties.

9.6 Online infringement and cross-border enforcement

Digital infringement can involve websites, social media platforms, online marketplaces, file-sharing systems, streaming services, and international hosting arrangements.

The territorial nature of intellectual property rights can make enforcement difficult where the claimant, infringer, platform, server, and audience are located in different countries. The relevant court may need to consider jurisdiction, applicable law, territorial effects, and the recognition or enforcement of judgments.

EU law provides mechanisms that facilitate cross-border judicial cooperation and the enforcement of certain intellectual property rights. The Digital Services Act also forms part of the wider regulatory framework governing online intermediary services, although it does not replace the substantive rules of copyright, trade mark, patent, or design law.

Rights holders should preserve evidence of online infringement, including dates, URLs, screenshots, transaction records, and relevant communications. The legal significance of each item depends on the nature of the claim and the applicable procedural rules.

10. The Relationship Between Intellectual Property Rights

10.1 Cumulative protection

A single commercial product may benefit from several forms of intellectual property protection.

Consider a company that develops a new electronic device. Its technical operating mechanism may be protected by a patent. Its external appearance may qualify for design protection. Its brand name and logo may be registered as trade marks. The software installed on the device may be protected by copyright. Confidential manufacturing processes may qualify as trade secrets.

These rights are complementary rather than interchangeable. Each protects a different legal interest and has different conditions and limits.

A business should therefore avoid relying on a single intellectual property right where several forms of protection may be available. A patent may expire after a limited period, while a trade mark can potentially be renewed indefinitely. Copyright may protect software expression, but not every underlying technical concept. Trade secret protection may preserve confidential know-how, but only while the statutory conditions remain satisfied.

10.2 Choosing the appropriate form of protection

The appropriate legal strategy depends on the nature of the creation and the business objective.

• A novel technical solution may be suitable for patent protection if it satisfies the patentability criteria.
• A product’s visual appearance may be protected through design registration and, where appropriate, copyright.
• A name or logo used to identify goods or services may be protected by trade mark registration.
• A book, article, photograph, film, or software program may qualify for copyright protection.
• Confidential technical or commercial information may be protected as a trade secret if secrecy is maintained and the statutory conditions are met.

The choice is not always straightforward. Patent disclosure may be commercially undesirable where the invention can be kept secret and independently protected through confidentiality measures. Conversely, trade secret protection may be insufficient where competitors can easily reverse-engineer a product once it enters the market.

The decision should take account of the expected commercial life of the innovation, the likelihood of independent development, the cost of registration and enforcement, the territories involved, and the ability to preserve confidentiality.

10.3 Intellectual property and competition

Intellectual property law grants exclusive rights, but it does not remove the application of competition law. The existence of a patent, trade mark, or copyright does not automatically justify every form of commercial conduct.

EU and French competition law may become relevant where licensing arrangements, collective conduct, market power, or contractual restrictions distort competition. The exercise of intellectual property rights must therefore be considered alongside the applicable rules on restrictive agreements, abuse of dominance, and other competition concerns.

The legal system seeks to balance innovation incentives with market access, consumer interests, and the preservation of fair competition. Intellectual property is intended to reward and encourage creation, not to create an unrestricted licence to engage in anti-competitive conduct.

12. Frequently Asked Questions

1. What is intellectual property law in France?

French intellectual property law protects original creative works, inventions, distinctive commercial signs, product designs, and qualifying confidential business information. Its principal statutory framework is the Intellectual Property Code, with trade secret protection primarily contained in the Commercial Code.

2. Does copyright protection require registration in France?

No. Copyright arises automatically when an original intellectual work is created. Registration is not required, although authors may use deposits, dated records, contracts, and other evidence to establish authorship and the date of creation.

3. What works are protected by French copyright law?

Protected works may include novels, articles, poems, music, films, photographs, paintings, sculptures, architecture, illustrations, software, and other original forms of expression. The work must satisfy the originality requirement.

4. Does copyright protect ideas?

No. Copyright protects the original expression of an idea, not the abstract idea itself. General themes, methods, concepts, facts, and principles are not protected merely because someone first expressed or discussed them.

5. What are moral rights under French copyright law?

Moral rights protect the personal relationship between the author and the work. They include rights concerning attribution, disclosure, respect for the work, and withdrawal or reconsideration under statutory conditions. They are generally perpetual and cannot be transferred in the same way as economic rights.

6. How long does copyright last in France?

The ordinary economic-rights term is the author’s lifetime plus 70 years, calculated according to the statutory calendar-year rules. Specific provisions apply to collaborative, audiovisual, anonymous, pseudonymous, and collective works.

7. Can a company own copyright in a work created by a freelancer?

Yes, where the relevant rights have been validly transferred to the company. However, payment for the work does not automatically transfer all copyright. The agreement should identify the rights transferred and the scope of exploitation.

8. Does an employer automatically own every work created by an employee?

No. French law has specific rules for certain categories, including software and employee inventions, but there is no universal rule transferring every copyright work created during employment to the employer.

9. What is a trade mark?

A trade mark is a sign that distinguishes the goods or services of one undertaking from those of other undertakings. It may consist of a word, name, logo, slogan, sound, shape, or another qualifying sign.

10. Where are French trade marks registered?

French national trade marks are registered through the INPI. Applicants seeking protection throughout the European Union may instead apply for an EU trade mark through the EUIPO.

11. How long does a French trade mark last?

A French trade mark registration generally lasts ten years and may be renewed indefinitely for successive ten-year periods, provided the required formalities and fees are completed.

12. Can a trade mark be lost through non-use?

Yes. A trade mark may be vulnerable to revocation where it has not been put to genuine use for the relevant goods or services during the statutory five-year period, unless proper reasons for non-use exist.

13. What is the difference between a trade name and a trade mark?

A trade name identifies a business or commercial undertaking, while a trade mark distinguishes particular goods or services. They may overlap in practice, but their legal functions and methods of protection are not identical.

14. What is a patent?

A patent is an exclusive industrial property right granted for a qualifying technical invention. It allows the holder to prevent certain unauthorised commercial acts involving the invention for a limited period.

15. What are the conditions for obtaining a French patent?

An invention must generally be new, involve an inventive step, and be capable of industrial application. It must also fall within patentable subject matter and satisfy the applicable disclosure and application requirements.

16. Can an abstract idea or business method be patented?

Not merely because it is commercially useful or innovative. Abstract ideas, mathematical methods, and business methods as such are excluded. A computer-implemented invention may nevertheless qualify where it makes a relevant technical contribution and satisfies the other patentability requirements.

17. How long does a French patent last?

A French patent generally lasts 20 years from its filing date, subject to payment of renewal fees and the applicable legal conditions. Certain regulated products may qualify for supplementary protection certificates.

18. Should an inventor publish an invention before filing a patent application?

Generally, no. Public disclosure may destroy novelty and prevent a valid patent from being granted. Inventors should consider filing strategy before publishing, presenting, demonstrating, or commercially disclosing the invention.

19. What happens when an employee creates an invention?

Article L611-7 of the Intellectual Property Code distinguishes mission inventions, certain attributable non-mission inventions, and non-attributable inventions. Ownership and remuneration depend on the statutory category and the circumstances of creation.

20. What do industrial designs protect?

Industrial designs protect the visual appearance of products, including their shape, contours, colours, texture, materials, and ornamentation. They do not ordinarily protect technical functions as such.

21. How long does design protection last in France?

A registered French design is initially protected for five years and may be renewed in successive five-year periods up to a maximum of 25 years.

22. Can a product design also be protected by copyright?

Yes, if the design satisfies copyright’s originality requirement. Design protection and copyright protection have different conditions and may coexist.

23. What is a trade secret under French law?

A trade secret is information that is not generally known or readily accessible, has commercial value because it is secret, and is protected by reasonable measures taken by its lawful holder to preserve confidentiality.

24. Are customer databases and business strategies protected as trade secrets?

They may be, provided that they satisfy the statutory conditions. Their confidential nature alone is insufficient: they must also have commercial value arising from secrecy and be subject to reasonable protective measures.

25. Is reverse engineering illegal in France?

Not automatically. Certain forms of observing, studying, disassembling, or testing a lawfully acquired product may be permitted under trade secret law. Contractual restrictions and other intellectual property rights may nevertheless affect the legality of the activity.

26. Can a former employee use confidential information from a previous employer?

The answer depends on the information, how it was obtained, the employee’s contractual and statutory obligations, and whether the information qualifies as a trade secret. General professional experience and skills should be distinguished from unlawfully retained or disclosed confidential business information.

27. Can trade secret protection prevent whistleblowing?

Not in every circumstance. French law recognises exceptions protecting specified disclosures made in the public interest, including certain disclosures of unlawful activity or misconduct in good faith and under the applicable statutory conditions.

28. What is the difference between a patent and a trade secret?

A patent protects a qualifying invention through a registered exclusive right in exchange for public disclosure. A trade secret protects qualifying confidential information against unlawful acquisition, use, and disclosure, provided that secrecy is maintained. A patent has a defined statutory term; trade secret protection may continue while its conditions remain satisfied.

29. What happens if someone infringes intellectual property rights in France?

Depending on the right and the circumstances, the rights holder may seek injunctions, damages, evidential measures, withdrawal or destruction of infringing goods, and other statutory remedies. Certain infringements may also result in criminal liability.

30. Can intellectual property rights be transferred or licensed?

Yes. Copyright, trade marks, patents, and designs may be assigned or licensed subject to their respective legal requirements. Trade secrets may also be made available through contractual arrangements that regulate access, use, and confidentiality.

Conclusion

French intellectual property law provides a comprehensive framework for protecting creativity, technical innovation, commercial identity, product appearance, and confidential business knowledge. Its different branches reflect the fact that intellectual and commercial value can arise in many forms: a novel may derive value from its original expression, a pharmaceutical product from its technical invention, a consumer product from its design, a business from its brand, and a technology company from confidential algorithms or development methods.

The legal framework is not based on a single universal right. Copyright, trade marks, patents, industrial designs, and trade secrets protect different interests, arise under different conditions, and operate for different periods. Understanding those distinctions is essential to determining what protection is available, who owns it, how it may be exploited, and what remedies may be pursued when it is unlawfully used.

France combines a strong tradition of authors’ rights with a developed industrial property system and an increasingly integrated European framework. The INPI, the French courts, EU institutions, the European Patent Office, and international organisations all contribute to the protection and administration of intellectual property rights. For authors, inventors, businesses, researchers, and creators, the practical challenge is not merely to obtain protection, but to select the appropriate rights, establish ownership, preserve evidence, comply with registration and contractual requirements, and enforce those rights proportionately.

Intellectual property law ultimately seeks to reconcile two important objectives: encouraging individuals and enterprises to create and innovate, while ensuring that exclusive rights do not become an unjustified barrier to competition, access to knowledge, cultural development, or the public interest. That balance is central to the modern French system and to the wider European and international framework within which it operates.
