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.

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 protection of semiconductor topographies is governed by the Law of 29 December 1988 on the Legal Protection of Topographies of Semiconductor Products.

Last modified 13 Jun 2024

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.

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.")

Last modified 13 Jun 2024

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.

Any signs (such as, but not limited to, names, designs, imprints, stamps, letters, numerals, shapes of goods or their packaging, colors and slogans) that may be represented graphically and may be used to distinguish the goods or services of a company are eligible to be registered as individual trademarks. However, signs solely comprising a shape which is imposed by the very nature of a product, which gives the product substantial value or which is necessary for obtaining a technical result may not be registered as trademarks.

Trademark protection requires the successful completion of a trademark registration process.

In order to be registered, the sign must have a sufficient "distinctive character." Such distinctive quality is not a constant but a variable. This means that a rather weak trademark at the time of registration may become a strong trademark through intensive advertising and enforcement, or, conversely and failing sufficient advertising and enforcement, that a strong trademark may become a weak trademark with a smaller scope of protection or even become the normal commercial description of a product or service for which it is registered as a result of the activity or inactivity of its owner, in which case the trademark will be declared as lapsed.

A registered trademark will give its owner an exclusive right to prevent any 3rd party, without its consent, from:

• Using in business a sign that is identical to the trademark for goods or services that are identical to those for which the trademark is registered.
• Using in business a sign that is identical or similar to the trademark because the goods or services covered by the trademark and the sign are identical or similar and there is a risk of confusion in the mind of the public because of the risk of association between the sign and the trademark.
• Using in business a sign which is identical or similar to the trademark for goods or services which are not similar to those for which the trademark is registered, where the trademark enjoys a reputation in the Benelux territory and where use of the sign without due cause would take unfair advantage of or be detrimental to the distinctive character or the reputation of the trademark.
• Using a sign for purposes other than those of distinguishing the goods or services, where use of the sign without due cause would take unfair advantage of or be detrimental to the distinctive character or the reputation of the trademark.

There is no Luxembourg trademark system per se. Luxembourg is party to the Benelux Convention, and as such, Benelux trademarks are in effect in Luxembourg alongside EU trademarks and international trademarks designating Benelux.

Trademarks are governed by the Benelux Convention on Intellectual Property of 25 February 2005 as approved by the Law of 16 May 2006, as amended.

The Directive (EU) 2015/2436 of the European Parliament and the Council of 16 December 2015 to approximate the laws of the Member States relating to trademarks has been implemented in Luxembourg through the Law of November 17, 2016 and the Law of July 20, 2018 approving the protocol amending the Benelux Convention in the field of intellectual property.

Furthermore, as far as EU trademarks are concerned, Regulation (EU) 2015/2424 of the European Parliament amending Council Regulation (EC) No 207/2009 on the Community trademark and Community Regulation (EC) No 40/94 on the Community trademark, and repealing Commission Regulation (EC) No 2869/95 on the fees payable to the Office for Harmonization in the Internal Market, has now come into force. Most notably, it included a name change for the traditional Community marks to European Union marks as well as a change from the traditional OHIM to EUIPO.

Also, the European Union trademark regime, which is applicable across all EU Member States, is regulated by Regulation (EU) 2017/1001 of the European Parliament and of the Council of June 14, 2017; Commission Delegated Regulation (EU) 2018/625 of March 5, 2018 supplementing Regulation (EU) 2017/1001 regulate the European trademark regime, which is applicable across all EU Member States; and Commission Implementing Regulation (EU) 2018/626 of March 5, 2018 lays down detailed rules for implementing certain provisions of Regulation (EU) 2017/1001.

Finally, on October 27, 2023 the Regulation (EU) 2023/2411 of the European Parliament and of the Council of October 18, 2023 on the protection of geographical indications for craft and industrial products and amending Regulations (EU) 2017/1001 and (EU) 2019/1753 (“Regulation”) was published.

This Regulation introduces a new EU intellectual property right, extending the protection for geographical indications (“GI”) to craft and industrial products. Previously, only agricultural products, wine and spirit drinks could enjoy EU GI protection, and only a few Member States had implemented a dedicated legal framework at national level to acknowledge and safeguard GI’s for craft and industrial products

The exclusive rights encompassed by a trademark are obtained by registration. An application for registration may be filed by anyone (eg, private persons, public authorities or companies) and does not need to be filed by the enterprise that will commercialize the trademark.

No protection to trademark owners is guaranteed without registration unless such unregistered trademarks are well known.

No specific provisions are foreseen in Luxembourg law with respect to co-ownership of trademarks.

Independently of the transfer or all or part of a business, a trademark may be transferred for all of some of the goods or services for which the trademark was filed or registered. A trademark may also be the object of a license for all or some of the goods or services for which the trademark was filed or registered.

• Compensation of material and non-material damages, which consist of:
  • Losses suffered, including costs and expenses imposed on it for the investigation and determination of the infringements and the inconveniences connected with the proceedings the trademark holder is forced to institute, loss of reputation, prejudice to the commercial value of the trademarks and loss of market share

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:

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.

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.
