The Patent Litigation Law Review: Brazil


Brazil has a civil law system. Its legal framework is composed of numerous ordinary laws, subject to the provisions of the Federal Constitution of 1988 (the Constitution). The protection and enforcement of patents is governed by the Industrial Property Law (Law 9279/96) (IP Law), a Federal Law. Brazil is a party to several international treaties, including: (1) the WIPO Paris Convention for the Protection of Industrial Property 1883 (Paris Convention); (2) the Patent Cooperation Treaty 1970; and (3) the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights 1994 (TRIPS).

Besides the IP Law, civil patent actions must comply with the standards of the Brazilian Civil Procedure Code (Law 13.105/15), while criminal patent proceedings follow the Criminal Procedure Code (Decree Law No. 3.689/41).

The normative rulings of the Brazilian Industrial Property Office (BPTO), the governmental body in charge of granting patents in Brazil, are also relevant to patent litigation.

Brazil recognises arbitration proceedings, which are governed by the Brazilian Arbitration Law (Law 9307/96) and also by the Civil Procedure Code. Brazil is a signatory of the UN Convention on the Execution and Enforcement of Foreign Arbitral Awards 1958, subject to the recognition of foreign awards by the Superior Court of Justice. As patent infringement cases usually arise from non-contractual relationships, arbitration proceedings are limited.

All proceedings in Brazil (both court and administrative) must be carried out in Portuguese, which is Brazil's official language. In arbitration proceedings, the parties can agree on a different language.

Although the law is the main source, Brazilian legal system also recognises jurisprudence, analogy, common customs and the general principles of law as methods of resolving disputes. The Brazilian Civil Procedure Code also allows parties to produce any evidence not forbidden by law.

Types of patent

The IP Law establishes the following types of patents: (1) patents of invention; and (2) utility models (industrial designs are not considered a patent in Brazil, but the litigation proceeding is quite similar).

A patent of invention must fulfil the following requirements: (1) novelty; (2) inventive step or non-obviousness; and (3) industrial utility.

Some subject matters are not considered as inventions (Article 10 of the IP Law), and others are not patentable (Article 18 of the IP Law).

The patent of invention will remain valid for a 20-year period, counted from the date of publication of the application. This period cannot be renewed. However, owing to the BPTO's backlog, the IP Law states that the validity of a patent of invention will be effective for at least 10 years, irrespective of the date of filing.

The patent administrative proceeding is very time-consuming. Currently, the average time to obtain a patent is about 10 to 12 years from the filing date.2

A utility model can be granted for an object of practical use, or part of it, if it:

  1. is susceptible to industrial application;
  2. has a new form or arrangement;
  3. involves an inventive act; and
  4. results in a functionality improvement in its use or manufacture.

Utility models remain valid for a 15-year period, counted from the date of publication of the application (this period is not renewable). The IP Law also states that the validity will never be less than seven years. The average time to attain a utility model is six to nine years.

Procedure in patent enforcement and invalidity actions

Patent infringement actions, for both civil and criminal proceedings, are filed before state courts. Some states (such as São Paulo and Rio de Janeiro) have lower civil courts and chambers specialised in corporate law, which also includes industrial property matters (such as patent litigation). Otherwise, the majority of judges are not familiar with these matters.

Patent invalidity actions are filed before federal courts, with the necessary participation of the BPTO as a defendant. For invalidity actions filed exclusively before the Federal Court of Rio de Janeiro, the court issued an Ordinance3 stating that the BPTO will figure, in principle, as a defendant. The BPTO has no jurisdiction over patent invalidity actions, which are decided exclusively by federal judges. If invalidity is granted, the BPTO will publish the cancellation of the patent in its Official Gazette. The parties are also allowed to hire their own technical assistants.

Only lawyers duly registered before the Brazilian Bar Association can represent parties before the courts.

The following can bring an infringement action:

  1. the patent holder;
  2. an exclusive or non-exclusive licensee (with powers to enforce the patent);
  3. distributors (with specific powers to enforce the patent); and
  4. any party that has a procedural interest to defend the patent (such as a commercial representative, franchisee, etc.) and is formally invested by the patent holder with the powers to defend the patent.

Invalidity actions can be filed by the BPTO or any party with 'lawful interest', who is defined as any party affected by the exclusivity given by the patent.

i Statutes of limitation

The patent owner will be barred from collecting damages for its unwarranted exploitation for five years following the occurrence of the infringement act, by express disposition of the IP Law. With respect to an inhibitory order, the term will be 10 years upon the occurrence of the infringement act. In certain cases, judges understand that the statute of limitations begins when the patent owner becomes aware of the infringement act. However, another doctrinal line understands that patent infringement is a constant act, so the statute of limitations period is continually renewed while illicit acts are practised, thus lengthening the end of the deadline for filing a lawsuit.

The Brazilian IP Law also establishes that a nullity action may be filed at any time during the validity of the patent.

ii Level of proof

The assessment of patent infringement is made through a technical comparison between the patent claims and the product, process or service put on the market by the infringer. The parties, their technical experts and the court expert present their technical reports. The judge is not obliged to follow the opinion of the court expert and can decide, based on other evidence attached to the records, as long as they explain the reasons for such adoption.

According to the most recent jurisprudence, the damages for patent violation are presumed (in re ipsa) once the patent violation is evidenced. The injured party will only need to prove the extent of the damages for the purposes of calculating the indemnity amount.

For granting of injunctions to compel the defendant to immediately cease exploitation of the patent, the patent owner must show the infringement beyond a reasonable doubt. Considering the technical aspects involved in patent infringement cases, injunctions are more difficult and granted only when the judge is convinced by the technical reports attached by the plaintiff.

In invalidity actions, the plaintiff must prove the lack of fulfilment of the legal requirements or the violation of any section of the IP Law by the patent. A court expert will be listened to, together with technical experts speaking on behalf of the parties. The BPTO will also bring its own technical opinion, based on its analysis during the administrative process.

There is no discovery in Brazil.

iii Amendments

Any claims amendments must be filed before the request for examination. According to the IP Law and BPTO Resolutions, after the request for examination of a patent application, amendments (voluntary or not) to the claim set that broaden the scope of the claimed subject matter will not be accepted and these amendments will be refused, even if just one claim was broadened.

iv Time and costs

Apart from the fees privately agreed between a party and its lawyer, the official fee for filing a lawsuit in Brazil varies from state to state and is around 1 per cent of the total value of the lawsuit, as indicated on the claimant's complaint. There are minimum and maximum caps on this fee, independent of the percentage.

In addition, there is a mandatory loss of suit fee, payable to the winning party's lawyer, fixed by the judge and ranged between 10 per cent and 20 per cent of the total value of the lawsuit.

There are additional non-regular expenses; for example, the remuneration of technical experts and fine for bad faith litigation.

To conduct a patent infringement or invalidity lawsuit in Brazil, that runs through all instances, we estimate that around US$150,000 could be spent. This amount will vary depending on the complexity of the case value and comprises the attorney fees, the court costs (as the official fee for filing a lawsuit, among other things), the official expert's and one particular expert's fees. If the case involves two or more technical evidences then the costs will be higher.

These fees (except for the fees privately agreed between a party and its lawyer) are recoverable from the losing party, at least in part. The judge will fix the sums due by the defeated party in the final decision.

Nowadays, as most courts have already adopted electronic proceeding, a lawsuit could last about one to two years to be judged in the first instance, depending on the level of proofs, the need to produce expert evidence, etc. At the court of appeals, the lawsuit could last another one to two years until a final decision. If the lawsuit is sent to the superior courts, the average time for a final judgment is about two to three years.

v Injunctions

There are two types of preliminary orders in Brazil: evidence-supported relief and urgent relief.

An urgent relief is granted to protect a right that must be fully confirmed by a final decision. The urgent relief can be requested in advance of or during the lawsuit. The urgency must be contemporary with the filing of the lawsuit. The plaintiff will only request the granting of the urgent relief, without indicating the basis for the main proceedings in the first instance. After that, if the urgent relief is granted in advance, the plaintiff will have 15 days from the granting to start main proceedings to confirm the measure. In addition, the defendant will have the same deadline to appeal against the decision. If the defendant files no appeal, the decision will become final and unappealable, and the urgent relief will stabilise and become definitive, without the need for the plaintiff to file for main proceedings.

To obtain an urgent relief during the lawsuit, the claimant must start the main proceeding and request the judge to anticipate some parts of the final decision. The requirements for an urgent relief are:

  1. unequivocal evidence of the likelihood of the rights invoked;
  2. grounded fear of irreparable, or hardly repairable, injury (urgency); and
  3. the injunction requested cannot be irreversible.

Preliminary injunctions can be granted without hearing the other party (ex parte) when there is a real risk that this party can frustrate the hearing, or in cases where urgency is so great that it is not possible to wait for a hearing of the other party. The judge has discretion to require the posting of a bond or another fiduciary guarantee as a condition for the injunction.

In patent invalidation actions, it is also possible to request a preliminary injunction order to stay the effects of the patent until the issuance of a final decision. However, injunctions are rarely granted in these actions, as the existence of the right relies on the patent owner, who followed all administrative procedures for granting of the patent by the BPTO. Therefore, the patent is prima facie valid.

Finally, there is the evidence-supported relief, granted by the judge regardless of urgency, based on the following grounds:

  1. it is characterised as the abuse of the right of defence or manifest interest in extending the lawsuit by a party;
  2. when the allegations are proved only with documents and there is an identical precedent (this is very hard to admit in patent infringement actions, owing to the need to produce independent technical evidences); and
  3. when the initial petition is instructed with sufficient documentary evidence to prove the plaintiff's right, and the defendant does not present other evidence capable of generating reasonable doubt in the judge's conviction (this is also very hard to admit in patent infringement actions owing to the need to produce independent technical evidence).

Patent holders could face liability for threatening infringement proceedings if they falsely accuse the other party, bringing a lawsuit for an infringement that has not occurred, or even if they misrepresent the other party's customers. In this case, an indemnification action could be filed.

Substantive law

i Infringement

The patent protection is determined by its claims, and interpreted based on the specifications and drawings. Those claims must: (1) be substantiated in the specifications; (2) characterise the particulars of the application; and (3) define clearly and precisely the subject matter that is the object of the protection.

According to the IP Law, the patent owner has the right to prevent third parties from, without its consent, producing, using, offering for sale, selling or importing a product that reproduces the object of the patent and a process or a product directly obtained from a patented process. The patent holder also has the right to prevent third parties from contributing to infringing acts committed by others.

The assessment of patent infringement is usually made through a technical comparison between the patent claims and the product, process or service put on the market by the alleged infringer.

In those cases, the defendant should prove that they did not reproduce the object of the patent, taking into account all the independent claims and specifications of the patent. That argument should be confirmed by means of technical evidence stating that the defendant's products or services do not reproduce the object of the plaintiff's patent.

Criminal proceedings must be preceded by a preliminary search and seizure measure, conducted by two court experts who will prepare an expert report on the infringement. In such cases, the judge appoints a person to act as legal depositary of the products. If the report confirms the infringement, the judge will ratify the technical report and the patent owner can file a private criminal action (the public prosecutor cannot file criminal actions for patent infringement).

Under the Industrial Property Law (Law 9279/96), the penalties for criminal patent infringement include terms of imprisonment from one month up to one year, or fines, often replaced by alternative penalties, such as payment of low amounts or rendering of community services.

The crime of patent infringement is considered to have been committed when the infringement either does not affect all the claims of the patent or is restricted to the use of means equivalent to the object of the patent (doctrine of equivalents).4

ii Invalidity and other defences

Invalidity can be argued at any time as a defence strategy, and is a standard argument in patent infringement actions. However, the Superior Court of Justice held that the invalidity of a patent can only be argued through a specific invalidity action, to be filed before a federal court, with the necessary participation of the BPTO.

A patent granted in violation of any provision of the IP Law could be declared null and void. The most common grounds are:

  1. non-fulfilment of the legal requirements: novelty; non-obviousness or industrial utility;
  2. lack of invention or utility model: according to Article 10 of the IP Law (see Section II);
  3. non-patentable subject matter: according to Article 18 of the IP Law (see Section II);
  4. lack of clear and sufficient description: according to Article 24 of the IP Law – 'The specification shall describe the subject matter in a clear and sufficient manner so as to enable a person skilled in the art to carry it out, and shall also indicate, to the extent applicable, the best mode of execution thereof';
  5. amendments after the examination: if the patent application is amended after the date of the examination request, it could be declared null (Article 32 of the IP Law); and
  6. exhaustion: the patent owner cannot block third parties when the product manufactured according to the patented technology is placed directly on the domestic market by the patent owner, or with his or her consent (national exhaustion). Also, imports by third parties of a product manufactured under a process or product patent shall likewise be allowed, considering that it has been placed on the foreign market directly by the patent owner or with his or her consent (international exhaustion).

Final remedies for infringement

The patent holder can seek some specific measures or orders to cease its violation.

i Permanent injunction

If the patent infringement is duly proved through the evidence produced during the lawsuit, the judge can grant a permanent injunction prohibiting the defendant from continuing to practise infringement acts; and condemn him or her to pay an indemnification. The final injunction must refer specifically to the acts of infringement, but can also affect suppliers and distributors of the infringing product. The effects of an injunction are limited to the defendant in the lawsuit, and cannot be opposed to third parties. Brazilian courts only have jurisdiction in Brazil; hence, an injunction only has effect on the national territory, but can be extended to other jurisdictions through rogatory letters.

ii Monetary remedies

According to the IP Law, the compensation can be calculated upon three different bases:

  1. the benefits that the patent infringer would have earned if the violation had not occurred;
  2. the benefits that the patent infringer actually earned; or
  3. the amount owed by the patent infringer to the patent holder under a hypothetical licence agreement signed between the parties.

The plaintiff can choose the most favourable criterion among the three above. Based on the chosen criterion, the judge will start a new phase of the lawsuit specifically to calculate the amount of the indemnification, and an accounting expert is often used to perform such analysis and calculations.

The plaintiff can also request indemnification for moral damages suffered by means of the patent infringement, when the plaintiff can prove that the company's business or reputation has been adversely affected by the infringement acts. However, moral damages are rarely granted in patent infringement cases.

There are no punitive damages in Brazil.

The indemnification values on infringement actions vary according to the nature of the patent, the time of violation, the economic capacity of the parties and their performance in the market. Thus, it is very difficult to provide statistics about the damages in patent infringement actions. According to the Brazilian Civil Code, the indemnity amount is calculated according to the extent of the damages, so the indemnity amount may vary depending on the specific case.

iii Delivery up or destruction of infringing goods

On infringement actions, the judge can also order the destruction of all illegal materials, matrices, moulds, negatives and other elements used to perpetrate the infringement acts. The judge can also order search and seizure measures to confiscate any machinery, equipment and device used for the infringement purposes.

iv Recall order

The judge can decide that the infringing party must withdraw from marketing all products, moulds and machines that unduly reproduce the patent. A recall order can be issued as a preliminary injunction or as a final decision, and the judge can impose a daily fine or other supporting measures in the event of non-compliance with the order.

The decisions will become enforceable only after the due service of the defending party and the attachment of the summoning letter to the case records.

Other types of patent proceeding

i Compulsory licence

It is very difficult to obtain the compulsory licence of a patent in Brazil. Under the IP Law, to date, there has been only one case concerning an HIV drug. Compulsory licences can be applied against a patent granted in Brazil in the following events:

  1. abusive exercise of the patent rights or abusive exercise of economic power duly evidenced and declared by an administrative or judicial decision;
  2. lack of exploitation of the patent in Brazil (except in case of economical infeasibility to do so, a situation in which the importation of the product will be authorised);
  3. commercialisation that is insufficient to meet market demand;
  4. a situation involving dependent patents; and
  5. national emergency or public interest events declared by the Brazilian government.

A compulsory licence based on items a to d can only be requested by one with a legitimate interest in its exploitation, and that shows technical and economic capacity to efficiently exploit the patent within the Brazilian market.

The interested party must submit a request to the BPTO, by proposing the licence terms and conditions. The BPTO will notify the patent owner, who must reply within 60 days. Once all the information required for the analysis of the pleading is gathered by the BPTO, it will decide as to whether the compulsory licence should be established and, if the parties does not reach an agreement on the remuneration (royalties) owed to the patent owner, the BPTO will determine such amount based on the circumstances of the case and the economic value of the licence.

ii Border measures

According to the IP Law: '[T]he customs authorities, ex officio or at the request of an interested party, may seize, at the time of clearance, any products carrying falsified, altered or imitated marks or otherwise bearing a false indication of source'. Despite the express mention of trademarks, this Article is also applied to patents. Therefore, there is a legal basis to require a preliminary injunction seeking the blocking of products at the border.

The judge can send an official letter to the customs authorities to block the entry of counterfeit products in Brazil. In patent infringement cases, however, this analysis by Customs is difficult because it is very technical. The common procedure in Brazil is to send a sample of the product seized by Customs to the trademark or patent owner, to ascertain whether or not there is a violation of its rights.


The unsuccessful party has several routes of appeal according to the Brazilian Civil Procedure Code. Each kind of appeal has a particular object, which could be the reform, the invalidation, the clarification or the integration of a judicial decision. The most common appeals are as follows.

i Interlocutory appeal

These are filed against decisions that do not close the proceeding, but only decide on incidental issues (named interlocutory decisions), such as decisions that grant or deny preliminary injunction requests. The interlocutory appeal will be sent to the respective court of justice and the case records will be sent to a reporting judge. The appellant can ask for the granting of a staying effect. For this, the appellant must prove that the interlocutory decision could cause him or her serious damage, and demonstrate the urgency of the case. The merit of this sort of appeal is judged around six months from the filing date, but this deadline could be extended or reduced depending on the complexity of the case, the court in charge of analysing the appeal, etc. The official fee for filing an interlocutory appeal varies from state to state. In some locations, the filing is free of costs, but in other places, there are official fees that may vary from 1 per cent up to 5 per cent of the total value of the lawsuit.

ii Motions for clarification

These are filed against any decision rendered during the lawsuit, in any instance. This sort of appeal must have as its object the clarification of any addition, omission, lack of clarity or contradiction in the appealed decision. The same judge or court that rendered the challenged decision will judge the motion. The motion for clarification is judged more quickly, in about one to three months from the filing date, depending on the judge or court in charge of analysing it. There are no official fees to file a motion for clarification.

iii Appeals against a final first instance decision

These are filed seeking to overturn the final first instance decision. The appeal will be sent to the respective court of appeals, where it will be decided by three judges, and all the issues discussed at first instance could be re-analysed.

iv The appeals phase

In general, appeals have a staying effect. There are some exceptions, such as appeals against decisions that involve injunction reliefs, when the staying effect is not granted automatically. Nevertheless, the appellant can ask for the granting in a separate motion that will be examined by the reporting justice in charge of the appeal's judgment.

The main object of an appeal is to reform or invalidate the first instance decision. It is possible to raise all the arguments on the merits already raised at first instance. The final decision is adopted by a majority vote. It is difficult to predict the exact time frame, but an appeal is usually judged in about one to two years from being received by the court of appeals. However, this deadline can be extended or reduced depending on the specific court and the complexity of the case.

New evidence can be brought at the appeal phase. However, some requirements must be fulfilled. For example:

  1. new evidence cannot be an indispensable document that should have been presented with the complaint;
  2. new evidence cannot be presented at the appeal phase as a bad faith strategy; and
  3. the counterparty must have the opportunity to access the new evidence and to present its manifestation about it.

Usually, at patent infringement or invalidity lawsuits, it is quite common to present a legal opinion drafted by a specialist in patents to strengthen the appellant arguments.

There are also the appeals against second instance decisions (named special appeals) that can be directed to the Superior Court of Justice (STJ) for judgment. Special appeals are only admitted when one of the following specific requirements are met: (1) clear violation of federal law provisions; or (2) different interpretations of the same issue by second instance courts.

Also, the special appeal cannot seek to discuss again the facts and evidence already presented and discussed at the lower instances (for this reason, it is difficult to admit the delivery of a special appeal to the STJ). If the special appeal is admitted, it will take two more years for the STJ to issue a decision. A final decision could take about two to three years to be issued.

The year in review

In April 2020, considering the covid-19 pandemic, some bills about patents' compulsory licensing (Bills No. 1.184/20, 1.320/2020 and 1.462/2020) were published at Brazil's House of Representatives. The main purpose of those bills is to modify Article 71 of the IP Law to expedite the compulsory licensing proceeding when a public health emergency is declared by the World Health Organization or competent national authority.

The IP Law, in its Article 71, currently provides the issuance of the patent's compulsory licence, as described in Section VI, in cases of national emergency or public interest. Therefore, some specialists understand that the pandemic can be considered a 'national emergency' and, because of that, the presented bills are unnecessary.

Bill No. 1.184/20 proposes the granting of the compulsory licence for the exploitation of patents during the health emergency provided for in the law relating to measures to contain the virus, while Bill No. 1.320/20 proposes the modification of the IP Law to expressly provide that BPTO must publish all patents and patent requests related to the specific health emergency, and also register the granting of the compulsory licence in the corresponding administrative procedure. On a similar note, Bill No. 1.462/20 proposes an alteration on the IP Law to authorise, automatically, the temporary and non-exclusive use, by the state or by private companies, of products or processes protected by patents in the context of the specific health emergency. None of those bills were voted yet but, as mentioned, it is unlikely that the House of Representatives will approve them, considering that the current IP Law provisions already authorise the compulsory licence in the context of a health emergency such as the covid-19 pandemic.


There are ongoing discussions about the (un)constitutionality of the paragraph of Article 40 of the IP Law that allows the extension of the patent term in case of delay in the examination of the application by the BPTO. That is because the BPTO often takes more than 10 years, which is the minimum period of validity of the patent (Article 40, IP Law) to grant an application. As a consequence of this legal provision, after 10 years, the period of time that BPTO takes to analyse the application is added to the total period of validity.

Considering that the maximum period of validity of the patent is 20 years, according to the above-mentioned Article 40 of the IP Law, if the BPTO took 20 years to analyse an application, the patent owner would still have the right to explore the patent for 10 more years, which would result in the use of the patent for more than 30 years in total (and that is not allowed considering the maximum period of validity).

This matter is being discussed in the context of the Direct Unconstitutionality Action No. 5529, which aims to declare unconstitutional the paragraph of Article 40 (IP Law), which will soon be judged by the Brazilian Supreme Court.

If the Supreme Court takes into consideration that TRIPS provides that no inventor of the signatory countries should have the legitimate expectation of exploring the patent protection for over 20 years, the legal provision will probably be declared unconstitutional.

Another alternative to this problem, which we defend, would be an amendment in the IP Law to provide that, if the application is not reviewed by the BPTO in 10 years, the patent should be considered granted.

4 According to the 'doctrine of equivalents', an infringement may occur if some characteristic or element of a product or service used by an unauthorised third party can be considered technically equivalent to the characteristic or elements of the claims of the patent. Courts also recognise the doctrine of equivalents in civil actions, as the IP Law allows the party to pursue applicable civil actions.
