The Intellectual Property Review: Portugal

Forms of intellectual property protection

In Portugal, there are two meanings of 'intellectual property' in both a broad and a strict sense. The former covers industrial property – patents, models, trademarks, logos, trade secrets, designations of origin and geographical indications – and the latter encompasses copyright and related rights. Therefore, for the sake of terminological simplicity, we will adopt the broad meaning of the expression throughout this chapter.

In the Portuguese legal system, provision is made for both more common intellectual property rights – patents, models, trademarks, logos, designations of origin, geographical indications and copyright – and less common rights, such as topographies of semiconductors and plant variety rights in the law. Finally, we have trade secrets or know-how, which, despite being well established in Portuguese legal practice – namely under unfair competition rules – were expressly included in legislation in December 2018 by Decree-Law No. 110/2018 to implement the EU Trade Secrets Directive.

The main legal instrument of protection is the Industrial Property Code (IPC), which was approved by Decree-Law No. 36/2003 and has been amended and updated by several legal acts.2

It was in these amendments to the IPC that the transposition into Portuguese law of the following legal instruments of the EU took place: Directive 98/44/EC of 6 July 1998 on the protection of biotechnological inventions; Directive 98/71/EC of 13 October 1998 on the legal protection of designs; Regulation No. 1768/92/EC of 18 June 1992 on the creation of a supplementary protection certificate for medicinal products; Regulation No. 1610/96/EC of 23 July 1996 on the creation of a supplementary protection certificate for plant protection products; EU Directive No. 2015/2436 of 16 December 2015 as regards trademarks; and EU Directive No. 2016/943 of 8 June 2016 as regards trade secrets.

Regarding the protection of copyright, this was laid down for the first time in 1927 in Decree-Law No. 13725 of 27 May 1927 (Regime of Literary, Scientific and Artistic Property). Later, the Code of Copyright and Related Rights was created by Decree-Law No. 46980 of 27 April 1966 and has undergone several changes since then.3

Although patents provide an important role in intellectual property rights, they do not present the main form of intellectual property protection in Portugal.

In 2021, 514 applications for the protection of industrial designs and 21,502 applications for the registration of trademarks and other distinctive trade signs, such as logotypes, were filed. However, only 2,124 applications for utility models, patents and complementary protection certificates were filed.4

Portugal is one of the EU countries with the highest number of trademark applications per one million inhabitants.

Recent developments

In accordance with the effort that is being made in the implementation of measures of access and simplification to the system of protection of trademarks and patents, and to ensure the compliance of the Portuguese legal system with the most recent EU Directives (No. 2015/2436 and No. 2016/943 concerning the harmonisation of trademarks and the protection of know-how and confidential information), they have been implemented by Decree-Law No. 110/2018 of 10 December 2018.

With regard to the harmonisation of trademarks, a more efficient and accessible system was created for companies and citizens, in terms of the speed of administrative procedures, predictability and costs, and in the definition of a set of rules for all trademark registrations, regardless of the trademark type.5

Regarding trade secrets, Decree-Law No. 110/2018 incorporates the transposition of the Directive on the protection of know-how and confidential information (trade secrets) against its illegal acquisition and use and disclosure by third parties, thereby protecting innovative companies and preventing the intellectual assets of these economic agents from being improperly used.

In addition to the inclusion of this topic in other articles of the IPC, the Decree-Law establishes the creation of five new articles on trade secrets. These new provisions concern the definition of trade secrets, the creation of a criminal offence in relation to their illegal attainment and disclosure and, consequently, the definition of what attainments and disclosures can be considered legally justified. A fine is also set for trade secret infringement, starting at €1,000 and potentially reaching up to €100,000. Finally, the law also makes provision for the preservation of evidence when trade secret damage is at stake.

Although the subject of trade secrecy is the main amendment, it is still important to mention another change foreseen in the Decree-Law.

This concerns the end of the ban on double patent protection in Portugal. Article 139(3) of the European Patent Convention gives Member States the freedom to decide whether an invention that is subject to a European and national patent can be doubly protected. This amendment allows for double protection, as was already possible in other countries such as Austria, Sweden and Norway.

Obtaining protection

i Trademarks

Trademark protection is regulated by Title II, Chapter 4 of the IPC. Trademarks may consist of a sign or set of signs capable of being represented graphically – namely words, including names of persons, designs, letters, numbers, sounds, and the shape of the product or its packaging – provided that such signs are capable of distinguishing the goods or services of one undertaking from those of other undertakings. They may also consist of advertising phrases for the products or services to which they relate, provided that they have a distinctive character, regardless of the protection that is granted by copyright.

Anyone who has a legitimate interest in protection may apply for registration.6

The trademark registration application consists of an application form addressed to the National Institute of Industrial Property (INPI) and written in Portuguese and the payment of a fee. The application for registration is usually filed online because it is more efficient, expeditious and economically more advantageous for the applicant. In the application, in addition to the applicant's personal data, the name of the trademark and the goods or services for which the mark is being applied for must be indicated, as well as the type of trademark in question (verbal, combined, three-dimensional), the colours used in the sign (in these cases it is mandatory to file a graphic representation of the sign) and, finally, if the applicant wishes to claim priority over the right, the country, the first application for registration of the trademark, and the date and number of that application should also be presented.

The application is later published in the Industrial Property Bulletin. From the date of publication in the Bulletin there is a period of two months for any possible oppositions from third parties who are interested in filing them.

If no oppositions are filed, the INPI studies the file. This study consists of an examination of the trademark and its comparison with other trademarks and distinctive signs.

The registration is granted if, after the examination, no grounds for refusal have been detected and the opposition, if there was any, is considered unfounded.

In Portugal, the average time between the filing of the application and the decision – grant or refusal – is approximately four months.7

The trademark registration is valid for 10 years from the date of the application and can be indefinitely renewed for equal periods.

ii Industrial designs

The design regime is laid down in Title II, Chapter III of the IPC and is defined as the designation of appearance in whole or in part of a product resulting from the characteristics of lines, contours, colours, shape, texture or materials of the product itself and its ornamentation.

As far as the registration procedure is concerned, applications for designs are very similar to those for trademarks, differing only in some aspects.

One of the differences concerns the documentation to be attached to the application. In trademark applications, it is necessary to attach a graphic representation only in certain cases, whereas, in the case of designs, it is always mandatory to attach a graphic or photographic representation of the design.

Another difference concerns its description. The applicant, on their own initiative or by notification of the INPI, may submit a description, containing not more than 50 words per product, referring only to the elements appearing in the representations of the design or sample presented, omitting references concerning novelty, individual character or technical value of the design.

Once the application for registration has been submitted to the INPI, the formal requirements established in the same Chapter shall be examined within one month.

If there are no irregularities or if they are remedied, the application will be published for possible oppositions, and if there are no oppositions, the application will be granted.

The validity of the registration is five years from the date of the request and can be renewed for periods of five years, up to the limit of 25 years.

iii Patents

Patents are regulated by Title I, Chapter I of the IPC. Any new inventions involving an inventive step might be subject to protection if they are capable of industrial application, even where they concern a product composed of biological material or containing biological material or a process that allows the production, treatment or use of biological material. The IPC further states that any inventions, whether products or processes, in all fields of technology, and new processes for obtaining already known products, substances or compositions may be patented.

As for the procedure for registering a Portuguese national patent, it is similar to the procedures mentioned above except for a few additional peculiarities.

In addition to the application, the applicant must file a description of the object of the invention, the drawings necessary for the perfect understanding of the description, an abstract of the invention, and the patent claims of what is new and characterises the invention (i.e., the claims that define the requested scope of protection).

If the applicant does not have all the elements stated above at the time of the filing, they can submit a provisional patent application, delaying the delivery of these elements by up to a maximum of 12 months; in this way they ensure the priority of the patent application. This provisional application has to be converted into a definitive application; otherwise, the application will be considered withdrawn.

If the application is submitted under regular circumstances, it will be published in the Industrial Property Bulletin 18 months from the date of submission (or at an earlier date at the request of the applicant), with the transcription of the abstract and international classification of patents. Once the publication has been made, any person may request a copy of the information contained in the application. After the deadline for oppositions has passed, and if none has been submitted, the INPI will take a decision within a month.

When the patent is granted, it is valid for a period of 20 years from the date of the application.

Applications for European patents may be filed not only at the European Patent Office but also at the INPI. Moreover, where the applicant for a European patent has their domicile or registered office in Portugal, the application must be filed with the INPI; otherwise, the patent will not have effect in Portugal unless the priority of an earlier application is claimed in Portugal.

These applications may be drawn up in any of the languages provided for in the European Patent Convention, in which case the applicant shall have one month from the date of the request to submit to the INPI the Portuguese translation of the description, claims and abstract, as well as a copy of the drawings, even if they contain no words to translate.

iv Copyright

Copyright is defined in Article 1 of the Code of Copyright and Related Rights as work. All intellectual creations of the literary, scientific and artistic domain that have been somehow externalised will be considered to be work. To be protected, the work must be original and, as a rule, the copyright will belong to the intellectual creator of the work.

The registration of copyright in most cases is not mandatory and therefore it will not be through registration that the right will be constituted. Its registration is therefore optional and will have declarative effects. This will not be the case unless unpublished work titles, newspaper headlines or periodical publications' titles are in question. In these situations, the registration will make the legal protection effective.

In the case of the registration of the right, the competent authority is the General Inspection of Cultural Activities, a department body attached to the Ministry of Culture.

The validity of copyright, as a rule, expires 70 years after the death of the intellectual creator.

Computer software is protected by copyright only, under Decree-Law No. 252/94 of 20 October 1994, which implemented EU Directive 91/250/EEC of 14 May 1991.

Enforcement of rights

i Possible venues for enforcement

Intellectual Property Court

In most cases, when there is an infringement of intellectual property rights, this infringement will be subject to civil law.8 In such cases, the action must be brought before the specialised court, namely the Intellectual Property Court.

Court of Criminal Jurisdiction

In addition to civil actions, there are also many cases of criminal offences for the infringement of intellectual property rights. When this happens, the competent court will be the criminal court of first instance. The most common cases of criminal offences are cases of product counterfeiting.

Arbitral Tribunal

The INPI is a partner of the Arbitration Tribunal (ARBITRARE), which presents itself as an institutionalised arbitration centre of national scope within the network of Portuguese arbitration centres supported by the state. The fact of ARBITRARE's existence means that many disputes are addressed to it through the INPI or even through the parties concerned. However, there is nothing to prevent other arbitral tribunals from being used.

ii Requirements for jurisdiction and venue

As noted above, the infringement of intellectual property rights might lead to civil or criminal action, thereby leading to the jurisdiction of the Intellectual Property Court or the Criminal Jurisdiction Court.

In Portugal, when the violation of the IP right is known, the first reaction of the applicant, either by themselves or through an agent, is generally to send a cease and desist letter to the infringer stating that they should cease the illegal actions under penalty of the applicant having to resort to the appropriate legal means to solve the problem. This notice is not mandatory but is an alternative means to avoid litigation. If, even after sending the cease and desist letter, the infringer continues to act illegally, the rights holder has the right to bring an action before the competent court. If, on the contrary, the offender accepts the notice, the parties may then try to reach an agreement (e.g., through arbitral tribunals).

In terms of consequences, the punishment of the offender can be determined according to three types of responsibilities.

Misdemeanour responsibility

The offender shall be punished with a fine of between €3,000 and €30,000, in the case of a legal person, and between €750 and €3,740, in the case of a natural person, when practising the following acts:

  1. unfair competition;
  2. use in their establishment advertisements, correspondence, products, or services or in any other way the name or insignia that constitutes a reproduction or imitation of a name, insignia or logo already registered by others;
  3. manufacturing, importing, acquiring, or keeping for themselves or for others constituent signs of registered trademarks, names, insignia, logotypes, designations of origin or geographical indications; and
  4. use in the name or insignia of their establishment or logotype the name or company name belonging to the applicant.

Civil liability

In addition to a fine, the offender may still be liable to compensate the rights holder for damage or losses and may be prohibited from practising certain activities.

The compensation will be calculated based on the profit obtained by the offender on the damage or loss of profit suffered by the injured party, taking into account the costs incurred in the protection, investigation and termination of the prejudicial conduct to their right. The rights holder may, in certain cases, be compensated for non-pecuniary damage.

The court, in its decision, may also determine accessory measures, such as temporary inhibition on the exercise of certain activities or professions, deprivation of the right to participate in fairs or markets, or the temporary or permanent closure of their establishment.

Criminal liability

In Portugal, the law provides for different types of sanctions depending on the type of crime committed.

A penalty of imprisonment of up to three years or a fine of up to 360 days will be applied to those who:

  1. manufacture the artefacts or products covered by the patent or utility model;
  2. employ or apply the means or processes that are the object of the patent or utility model;
  3. reproduce or imitate, totally or partially, a registered design, designation of origin or registered geographical indication;
  4. explore a registered design belonging to another;
  5. import or distribute products obtained by any of these modes;
  6. counterfeit, totally or partially, or by any other means reproduce a registered trademark;
  7. imitate a registered trademark, totally or partially, or its characteristic parts;
  8. use counterfeited or imitated marks or trademarks belonging to others; or
  9. use, in their products, services, establishment or company, a registered trademark belonging to another.

A penalty of imprisonment of up to 18 months or a fine of up to 120 days will be applied to those who sell, put into circulation or conceal counterfeit products.

A penalty of imprisonment of up to one year or a fine of up to 120 days will be applied to those who in bad faith obtain a patent, utility model or design registration that does not legitimately belong to them.

iii Obtaining relevant evidence of infringement and discovery

The Portuguese legal regime allows for certain types of evidence in court. Regarding intellectual property rights, the IPC expressly provides for measures to obtain evidence as well as measures to preserve evidence.

In respect of measures for obtaining evidence, when the evidence is in the possession, dependence or control of the opposing party or a third party, the interested party may request the court to have the evidence produced. At the time of the request to the court, the interested party must justify the existence by providing a sufficient summary of evidence of an infringement of the industrial property rights.

As regards measures for the preservation of evidence, these may be required whenever there is a breach or a fear that the third party will cause serious and difficult-to-repair damage to the industrial property right. Measures to preserve evidence may include a detailed description, with or without the taking of samples, or the actual seizure of the goods suspected of infringing industrial property rights and, when appropriate, the seizure of the materials and instruments used in the production or distribution of such goods, as well as the relevant documents.

iv Trial decision-maker

Since 2012, there has been a specialised court with jurisdiction to deal with intellectual property issues – the aforementioned Intellectual Property Tribunal. This court is currently composed of three judges specialised in intellectual property responsible for all litigation of first instance in intellectual property matters. This will not be the case if litigation is settled by alternative means.

v Structure of the trial

The procedure begins with the rights holder lodging an action before the court. These actions comprise the facts and the applicable law by which the infringement of the right is alleged. It is also at this time that the evidence is attached; however, there is nothing to prevent the court from subsequently requesting additional pieces of evidence. After the lodging of the action by the rights holder, the infringer may file a response to the action in the same terms as the author did.

After an initial assessment of the case by the judge, a preliminary hearing is usually scheduled and, normally, an attempt for the parties to reach an agreement is proposed by the judge. If there is no agreement, any existing irregularities of the process are resolved, the subject matter of the proceedings and themes of evidence are defined, and the process will then proceed to trial. It is during the trial that witnesses and experts are heard. Once the production of evidence has been completed and the final allegations have been handed down, the judge assesses the entire process and issues a decision. This decision is later published in the Industrial Property Bulletin.

vi Infringement

As mentioned above, when the rights holder sees their right threatened, they should propose an action. Although the action has to comply with the procedural requirements required by law (such as legitimacy, jurisdiction of the court, value of the case, among others), there is no obligation regarding its structure. However, the usual structure is a tripartite structure: facts that underlie the action, grounds of law and, finally, the requests (these are mandatory).

vii Time to a first-level decision

The time taken to reach a decision will depend on the type of action that has been proposed. When an action is brought before a court of criminal jurisdiction, the average decision time varies from a year and a half to three years. If it consists of an action of competence of the Intellectual Property Court, it is common to have a court decision up to six months from the date of the action.

viii Remedies

In the Portuguese law system, when transposing the Enforcement Directive,9 the legislature decided to regulate interim measures autonomously in the IPC and in the Code of Copyright and Related Rights. An article was then included in both with the following wording:

Whenever there is a violation or a fear of others causing serious and hard to repair damage to the industrial property right, the court may, at the request of the interested party, order the appropriate measures to:
a) inhibit any imminent infringement; or
b) prohibit the continuation of the violation.

In addition to precautionary measures, there are also evidence preservation measures, which are discussed above.10

ix Appellate review

The scarcity of available judicial resources obliged the national legislature to limit the admissibility of appeals, in particular appeals to the Court of Justice. Thus, it is possible to appeal the decision of the Intellectual Property Court to the court of appeal, but it will no longer be possible to appeal against this latter decision.

Appeals from the court of appeal will be admitted to the Supreme Court of Justice only under the civil procedural law, where appeals are always admitted to the Supreme Court. These situations are defined in the Portuguese Civil Procedure Code and are as follows:

  1. when the case is of a value higher than the jurisdiction of the court of appeal and the contested decision is unfavourable to the appellant in an amount above that court's jurisdiction; and
  2. regardless of the value of the cause and of loss, an appeal is always admissible:
    • when it is based on the violation of rules of international jurisdiction, on the rules of jurisdiction based on matter or hierarchy, or in the case of an offence of res judicata; and
    • in decisions rendered within the scope of the same legislation and on the same fundamental question of law, against the well-established jurisprudence of the Supreme Court of Justice.

x Alternatives to litigation


As mentioned above,11 arbitral tribunals have a relevant role in the area of intellectual property in Portugal. Arbitral tribunals appear to be the most used alternative to litigation in Portugal. In the Portuguese legal system, the judgment of an arbitral tribunal and the sentence issued by a court of law have the same legal force. If a party fails to comply with an arbitral decision, the opposing party is entitled to appeal to a court of first instance to execute the decision rendered by the arbitral tribunal. Arbitration proceedings have a maximum duration of 12 months.

Justices of the peace

Although arbitral tribunals are most often used, the interested parties may also resort to justices of the peace. However, justices of the peace are limited by the subject matter of the proceedings. These special instances have the competence to resolve only certain conflicts (e.g., those relating to contracts, property and consumption).

Usually, the procedure begins with the assignment of a mediator by the Ministry of Justice who will try to get the parties in conflict to reach an agreement. If this is not possible, the case is referred to a justice of the peace.12 The decision of the justice of the peace has the same value as a sentence of a traditional court. Finally, if the conflict has a value higher than €2,500, it will always be possible to appeal to a court of first instance to review the decision.


Lastly, mediation is possible. Once again, the resolution of the conflict is dependent on the parties, though there is also a mediator present. The difference between this alternative means of resolution is that, here, the mediator cannot decide; it is the parties themselves that must reach a decision together.

Trends and outlook

The social phenomenon of entrepreneurship is widespread across Europe; however, in recent years it has significantly increased awareness in Portugal of intellectual property and the importance of its protection. Along with the various initiatives that Portugal has been involved in,13 entrepreneurship has led to a greater awareness of the importance of protecting industrial property rights not only among companies and the public but also in the government. The measures created to ensure the effective protection of intellectual property rights are evidence of this.

Intellectual property is increasingly considered to be an asset both by the population and by companies, and a competitive advantage over third parties. A change has taken place in which intellectual property is assessed at its true value – as a business tool. Proof of this change of mentality can be seen in the changes proposed in the draft revision of the IPC, which, if approved, will greatly benefit the holders and future owners of intellectual property rights, giving them more means of defence, protection and reaction against infringements of their rights.
