The current trademark regulations in Brazil are mainly based on the Intellectual Property Law, which came into effect on May 15, 1997. The Brazilian Industrial Property Office is responsible for managing trademark affairs, and the official language is Portuguese. Trademark exclusive rights need to be obtained through registration. Trademark registration is not mandatory, but in order to protect the trademark or renew it, it must be registered in accordance with the law. The Brazilian trademark registration adopts the principle of "application first".

Currently, Brazil adopts the Nice Classification 11th edition of product and service descriptions and does not accept applications for multiple categories in one form. The elements that can be registered as trademarks in Brazil include: text, name, graphics, letters, color, three-dimensional logo, etc.

1. Non traditional markers such as music clips, sounds, and colors cannot be registered in Brazil.
2. Prohibited by law from being registered as a trademark;
3. The design of the trademark design applied for registration must not include government, official, public, ethnic, national characteristic badges, military insignia, markings, decorations, flags, or other designs that are identical or similar, whether they are domestic, foreign, or international;
4. There are no separate letters, numbers, or dates in the design of the trademark application, unless they have sufficient distinctiveness;
5. The design of the applied trademark design must not contain any text, graphics, or combinations that violate moral and customary standards, widely accepted behavioral standards, personal aggression, or insult religious customs and respected and praised emotions and beliefs;
6. The design of the registered trademark design cannot include the names and abbreviations of public institutions and their agencies that do not require trademark registration;
7. The design of the trademark design applied for registration cannot contain official or officially certified names, marks, and prizes used in art, culture, sports, society, economy, technology, or politics, as well as designs that can easily cause confusion by imitating the above names, marks, and prizes, unless the relevant parties and organizations provide corresponding authorization and authorization certificates;
8. The design of the trademark design applied for registration shall not have designs that imitate or replicate the titles, bonds, currencies, or notes of the federal, state, city, county, or regional governments of Brazil or other countries;
9. The design of a registered trademark design cannot include the name and signature of an individual, well-known pen names and nicknames, family names or portraits of others, or the name of an individual or group artist, unless the consent or permission of the corresponding rights holder or their heirs is obtained.

The Brazilian trademark is valid for 10 years after registration, starting from the date of registration; Renewal can be processed one year before the expiration date, with a grace period of 6 months; The renewal period is 10 years.

The invalidation or revocation application after trademark registration can generally be filed based on the following reasons:
1. Violating relevant laws and regulations;
2. Malicious registration;
3. If a trademark is not actually used in the country for five consecutive years after registration, anyone may apply for revocation; Except for force majeure.
Trademark revocation applications can be submitted to the Brazilian Industrial Property Office, which generally takes 2-3 years under current examination conditions.

The examination of trademark transfer by the Brazilian Intellectual Property Office is the same as that of the original applicant, without considering the registration status at the time of application, whether the application materials are complete or meet the requirements, only examining whether the applied trademark meets the registration conditions. The announcement period for trademark transfer is six months. If the applicant decides to transfer the trademark, they must submit an application three months before the expiration of the announcement period, otherwise they will not be approved.
