A number of laws may apply to commercial contracts depending on the type of contract and the industry involved. However, generally commercial contracts are governed by provisions contained in the Luxembourg Civil Code.

The Consumer Code in Luxembourg applies to business-to-consumer agreements, and the E-Commerce Law of 14 August 2000, as amended, applies to e-commerce transactions.

To qualify for copyright protection, a work must be original.

The same requirement of originality applies to the copyright protection of databases, which are considered original when they constitute the author's own intellectual creation by reason of the selection or arrangement of their contents.

There is no registration process for copyright protection; the author's right arises automatically with the creation. Mere ideas or concepts are not protected.

Copyrights are governed by the Law of 18 April 2001 on Copyright, Neighboring Rights and Databases, as amended.

In April 2019, the European Union adopted the Directive 2019/790 in order to adapt the existing framework of copyright and related rights to the digital age. This directive has yet to be implemented into Luxembourg law. A draft law No. 7847 is currently being discussed and, when adopted, should modify:

• The Law of 18 April 2001 on Copyright, Neighboring Rights and Databases, as amended
• The Law of 3 December 2015 on certain authorized uses of orphan works

Only natural persons (ie, individuals) who have created works may enjoy the status of an author, even where an author is an employee. However, there are some presumptions, such as those regarding the assignment of economic rights in computer programs, that automatically favor employers.

The Copyright Law includes a rebuttable presumption of authorship; the author is presumed to be the person under whose name the work is being disclosed.

Persons collaborating directly on the creation of a work become co-authors. Their copyright is indivisible. In these situations, the exercise of the right of co-authors is governed by agreement. Failing such agreement, no author may exercise this right in isolation, unless a court decision provides otherwise in case of a dispute. In a situation in which the contributions of the authors may be individually identified, those authors share the right to exploit their contribution in isolation provided that such exploitation is not done together with the contribution of another co-author and does not harm the joint work.

The economic rights of the author shall be freely assignable and transferable, in whole or in part, in accordance with the provisions of the Civil Code. In particular, they may be the subject of alienation or of an ordinary or exclusive license.

A specificity of Luxembourg copyright law is that it also allows the author to assign or transfer, in whole or in part, their moral rights to the extent that it is not prejudicial to their honor or reputation.

Given the implementation of the Directive 2004/48/EC of the European Parliament and of the Council of 29 April 2004 on the enforcement of intellectual property rights, right holders are entitled to similar remedies under most intellectual property laws in the European Union, which differ only slightly and which warrant both (interim and final) injunctive and monetary relief.

The possible civil and criminal remedies for copyright infringement are set out under Sections 8 and 9 of the Copyright Act.

Civil remedies are inter alia:

• Cessation of infringement
• Damages
• Publication and posting of judgment
• Daily monetary fine (articles 2059-2066 of the Luxembourg Civil Code)

Reference should also be made to the saisie-contrefaçon procedure (Section 8 of the Copyright Act), which allows a rights holder to enter, without prior warning but after authorization by the judge, the premises of an alleged infringer or an intermediary 3rd party in order to find evidence of and more information regarding infringements.

Criminal remedies are:

• Criminal fine
• Confiscation or destruction of infringing goods or goods that directly served the purpose of committing the infringements at hand
• In case of a bad-faith or fraudulent infringement, the sanction may include imprisonment
• Heavier sanctions in case of repeated infringement:
  • Possible combination of imprisonment and monetary fine
  • Permanent or temporary closure of the establishment ran by the condemned party for a maximum period of 5 years
  • Publication and posting of the judgment

The topography of a semiconductor product is protected if it is the result of its creator's own intellectual effort and is not commonplace in the semiconductor industry. Where the topography of a semiconductor product consists of elements that are commonplace in the semiconductor industry, it shall be protected only to the extent that the combination of such elements, taken as a whole, is the result of the creator's own intellectual effort and the combination is not commonplace in the industry. The protection extends solely to the topography and not to any concept, process, system, technique or encoded information embodied in the topography.

The rights holder has the exclusive and temporary right to reproduce and commercially exploit the topography (or import it to this end). The rights holder may, however, not assert this exclusive right (i) to prohibit reproductions of the topography that serve the sole purpose of analyzing or evaluating its techniques (ie, reverse engineering) and (ii) to act against any topography resulting from such analysis to the extent that it is the result of the creator's own intellectual effort and is not commonplace in the semiconductor industry.

The exclusive right related to the protection of topographies of semiconductor products come into existence on the earlier of:

• The date on which the topography was first commercially exploited anywhere in the world
• The date on which the application for registration was filed in due form

This exclusive right expires after 10 years, calculated from the end of the calendar year during which the exclusive right came into existence.

Exclusive rights will no longer be enjoyed or will expire if an application for registration has not been filed with public authority within 2 years of its first commercial exploitation.

Where a topography has not been commercially exploited anywhere in the world within a period of 15 years from its first fixation or encoding, the exclusive rights may no longer commence unless an application for registration has been filed within that period.

Last modified 13 Jun 2024

The ownership of the exclusive right is granted to the creator of the topography of a semiconductor product. Where this topography is created by an employee in the course of their employment, the employer shall be deemed the creator, unless otherwise agreed in writing. Where this topography is created under a contract other than a contract of employment, the person who has commissioned the topography shall be deemed the creator, unless otherwise agreed in writing.

The exclusive rights are not granted automatically but require a registration; they are freely licensable and transferrable, including to the successors in title of the rights holder.

Compensation for infringement is governed by the same provisions of the legislation on patents for invention. (See "Patents – Remedies for Infringement.")

An invention is eligible for patent protection if it satisfies 3 conditions:

• It is new
  • An invention is new if it does not fall within the relevant state of the art –meaning everything made available to the public before the date of filing of the patent application.

The novelty of an invention is not jeopardized if the invention was disclosed to the public in the course of 6 months prior to the filing of the application and it is due directly or indirectly to (a) an obvious abuse in relation to the applicant or (b) the invention has been displayed at an exhibition organized by the public authorities or an official international exhibition. In the latter case, the applicant shall declare, when submitting their application, that the invention was actually disclosed during an exhibition and furnish a relevant certificate.

• Inventive 
  • It is inventive if it, in regard to the state of the art, is not obvious to a person skilled in the art.
• Capable of industrial application
  • Finally, the term "industrial application" must be understood very widely as being able to be made or used in any kind of industry, including agriculture.

Patent protection requires the successful completion of a patent application process.

• A priority right is granted by the person who has filed an application for a patent for the same invention. In order to benefit from this priority right, registrations must be carried out before the end of the 12th month following the date of filing of the first application. In addition, the applicant must make a "statement of priority" when applying.
• Such priority right provides that the date of priority shall be the date of filing the application.
• Any person who, in good faith, prior to the patent application or the priority date, possessed in Luxembourg a justified right in the prior use of the patented invention is entitled to continue the exploitation of the invention, for personal use, notwithstanding the existence of a patent granted to a 3rd party.

The patent shall confer on its owner the right to prevent all 3rd parties not having their consent:

• From making, offering, putting on the market or using a product that is the subject matter of the patent, or importing or stocking the product for those purposes.

• From using a process that is the subject matter of the patent or from offering the process for use in Luxembourg territory, or when the 3rd party knows, or it is obvious in the circumstances, that the use of offering of the process is prohibited without the consent of the owner of the patent.

• From offering, putting on the market, using, importing or stocking for those purposes the product obtained directly by a process that is the subject matter of the patent.

• Supplying or offering to supply, in Luxembourg territory, a person other than a person entitled to exploit the patented invention the means of implementing, in that territory, the invention with respect to an essential element thereof where the 3rd party knows, or it is obvious from the circumstances, that such means are suited and intended for putting the invention into effect.

Patents have a duration of 20 years from the date of filing of the patent application. Renewal is not possible.

Exploitation of the invention is not a prerequisite for maintaining patent protection. However, if the invention is not exploited in Luxembourg or any other Member State of the Agreement Establishing the WTO for a period of 4 years following the date of patent application or for a period of 3 years following the grant of the patent, a compulsory license may be granted following a request to the court.

Unitary Patent System

Regulations (EU) No. 1257/2012 and No. 1260/2012 of 17 December 2012 implementing enhanced cooperation in the area of the creation of unitary patent protection set up the European Unitary Patent System. These regulations entered into force on 20 January 2013 and are applicable since June 1, 2023 which is the entry into force of the Agreement on a Unified Patent Jurisdiction establishing the Unified Patent Court

To date, 17 Member States have ratified the UPC Agreement (including the 3 Member States with the highest number of European patents in force in 2012: Germany, France and Italy). It is expected that further Member States will ratify the UPC Agreement in the coming years.

The unitary patent system makes it possible to get patent protection in up to 24 EU Member States by submitting a single application with the European Patent Office, thus simplifying the procedure and making it more affordable for applicants.

The Unified Patent Court (UPC) is an international court established by the participating EU Member States to deal with infringement and validity cases of unitary patents as well as European patents, thus eliminating costly parallel proceedings and increasing legal certainty. The unified patent jurisdiction will consist of a first level court in Paris (with a section in Munich) and a court of appeal in Luxembourg, as well as local divisions in several countries. From June 1, 2023, and for a transitional period of at least seven years, national courts will continue to have concurrent jurisdiction for "classic" European patents and supplementary protection certificates.

 The UPC's Court of Appeal and Registry are based 1, rue du Fort Thüngen, L-1499 Luxembourg, in the immediate vicinity of the Court of Justice of the European Union and the European Public Prosecutor's Office, thus reinforcing Luxembourg's position as the European Union's judicial center.

The Patents Law provides that the patent rights are owned by the inventor or their successor in title.

In case of joint ownership, each co-owner has a personal right to exploit the invention or give non-exclusive licenses if they compensate the other owner(s). An exclusive license may, however, only be granted with the consent of all co-owners. Each co-owner may act against infringement actions or assign any rights of the patent, but they must notify the other co-owners thereof. In the latter event that one of the co-owners wishes to assign their share, the other co-owners have a pre-emption right over the proposed assignment for a 3-month period from the moment they have been informed of the intention to assign. In addition, the co-ownership regime as specified in the Luxembourg Civil Code (815 et seq.; 1973a-1 et seq and 883 et seq) is not applicable to patent co-ownership.

If a patent application is submitted only by 1 owner without the involvement of the other joint owner(s), the other joint owner(s) may initiate legal proceedings requiring the transfer of the patent or the patent application as joint owner.

The possible remedies for infringement are set out under title IX "Trademark counterfeiting" of the Patent Act:

• Cessation of infringement (provisional or permanent), possibly accompanied by the penalty of a daily fine
• Publication of the judgment
• Damages to make good the harm caused
• Confiscation or destruction of infringing goods and of the instruments, devices or means specifically intended for committing the infringement

Reference should also be made to the description and saisie-contrefaçon procedures (Article 79 of the Patent Act), which respectively allow for:

• The drawing up of a detailed description of the allegedly infringing articles and the instruments that have served to commit the alleged infringement by a sworn expert.

• The unexpected seizure of allegedly infringing articles and the instruments that have served to commit the alleged infringement.

Both procedures serve the purpose of gathering evidence of and more information regarding infringements and may not exceed a period of 3 months from notification of the order to the person or to their domicile.

Since July 2, 2019, trade secrets are explicitly regulated in Luxembourg through the Law of 26 June 2019 on the protection of undisclosed know-how and commercial information (business secrets) against unlawful acquisition, use and disclosure.

To respond to the need for harmonization across borders, the Directive (EU) 2016/943 of the European Parliament and of the Council of June 8, 2016 on the protection of undisclosed know-how and business information (trade secrets) against their unlawful acquisition, use and disclosure brought both a common definition for trade secrets as well as more legal clarity as to the conditions guaranteeing the protection of a trade secret across the European Union.

The Law of 26 June 2019 on trade secrets (Trade Secrets Act) has finally transposed the abovementioned directive. While trade secrets used to be defined by case law, the new law now provides a legal definition of trade secrets, thereby allowing for further legal stability.

As provided by the directive, the Trade Secrets Act defines a "trade secret" as "information which meets all of the following requirements:

• It is secret in the sense that it is not, as a body or in the precise configuration and assembly of its components, generally known among or readily accessible to persons within the circles that normally deal with the kind of information in question.
• It has commercial value because it is secret.
• It has been subject to reasonable steps under the circumstances, by the person lawfully in control of the information, to keep it secret.

This definition is close to the definition of Section 39(2) of the TRIPS Agreement:

Reference should also be made to Section 1 (i) of the Commission Regulation (EC) 316/2014 of 21 March 2014 on the application of Article 101(3) of the Treaty on the Functioning of the European Union to categories of technology transfer agreements: "know-how" means a package of practical information resulting from experience and testing which is:

• Secret – that is, not generally known or easily accessible.
• Substantial – that is, significant and useful for the production of the contract products.
• Identified – that is, described in a sufficiently comprehensive manner so as to make it possible to verify that it fulfills the criteria of secrecy and substantiality.

While remedies for trade secret infringements used to be governed by tort law (article 1382 of the Civil Code), unfair competition law (Competition Act of 23 October 2011) and general criminal law (article 309 of the Criminal Code), as well as contract law (article 1134 of the Civil code) under the Trade Secrets Act, the trade secret holder may make use of measures and remedies, such as:

• Prohibitory injunctions
• Damages
• Corrective measures (eg, the destruction of the infringing goods)

As for most European jurisdictions, competition rules prevail over contractual arrangements. Licenses of trade secrets are subject to Commission Regulation (EC) 316/2014 of March 21, 2014 on the application of Article 101(3) of the Treaty on the Functioning of the European Union to categories of technology transfer agreements. Such licenses are exempted from the application of Article 101(1) of the treaty in case the parties' joint market share does not surpass certain thresholds and if the licensed technology rights have not expired, lapsed or been declared invalid or, in the case of know-how, for as long as the know-how remains secret, except if the disclosure of the know-how is the result of an action by the licensee (in which case the exemption shall only apply for the duration of the agreement). In any case, trade secrets licenses containing any of the hardcore restrictions listed in Section 4 of aforementioned regulation are not exempted.

Copyright

In case of a work commissioned by 3rd parties or works created by an employee in the performance of their tasks or upon instructions given by the employer, the employer or the commissioner is to be considered the assignee of the economic rights if the parties have expressly agreed to this in writing.

The original author retains the moral rights on the work but is in principle entitled to transfer them in whole or in part.

Patent

When the inventor is an employee and unless the parties have expressly agreed otherwise in writing, patent rights belong to the employer:

• When an industrial invention is made during the performance or fulfillment of the employment contract, whereby the inventive activity is deemed the objective and the employee is paid to invent and make researches
• When an industrial invention is made through the knowledge or use of technics or specific means to the employer or data procured by the employer

When a contract is drafted by 1 party and the other party merely has the opportunity to accept it (ie, the contract is not negotiated), some provisions must be specifically approved in writing by the other party in order to be enforceable against the party that has not drafted the agreement. Such provisions include those relating to limitation of liability, time limits, exclusivity, withdrawal rights and choice of venue.

For contracts approved online, it is a common practice to contemplate a second checkbox to specifically approve the relevant clauses. However, such second tick is not deemed sufficient, and consequently there is the risk that users challenge the enforceability of the provisions mentioned above while the other terms of the contract will remain valid.

Until mid-2016, the use of electronic signatures in the European Union was governed by Directive 1999/93 on a Community framework for electronic signatures (E-Signature Directive) as transposed into the national laws of 28 Member States of the European Union.

The Regulation (EU) No 910/2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC (eIDAS Regulation) was adopted in July 2014 and has been effective as of July 1, 2016. This eIDAS Regulation aims to provide more predictable regulatory environment and is directly applicable in all Member States of the European Union without having to be transposed in national legislation.

On November 8, 2023, the European Commission endorsed the provisional political agreement of the European Parliament and the Council of the EU including the key elements of the proposal for a legal framework for a European Digital Identity, also called eIDAS 2.0. This new version of the Regulation 910/2014 of July 23, 2014 aims to strengthen security and user confidence in digital interactions within the EU, and to create a digital environment that is both reliable and fluid.

Indeed, with the eIDAS 2.0 Regulation, it will now be possible to have a unique and recognized means of identification within the European Union. This will apply not only to identity documents, but also to all attributes (such as nationality, age or marital status) used to authenticate a person remotely.
