First of all, you should know that since you are not the owner of these world-wide music labels, you are not authorized to enforce said trademarks in Brazil. In that case, I will tell the most suitable strategy for preventing such a trademark infringement.
1- First, if your country has an online trademark database which is open to public, please investigate if there exists any trademark registration of these world-wide music labels in Brazil.
2- If you encounter some trademark registrations in relevant sector, then find and save a copy of these registrations in your file.
3-Create a special Evidences of Infrigement file. Begin to collect all documents in order to prove the infringement. Examples: Record everything on which you see the music labels. Photographs of the company, products, invoices, advertisements, brochures etc. If it is possible also collect sample products on which the trademark is used. Even you can record telephone conversations showing the infringement. Please keep in mind that you should always record the date on the evidence.
4-Then inform the authorized distributor in Brazil (if exists) of the holder company of these world-wide labels and then inform the main company by e-mail or fax. Tell them you collected some evidences and can send an electronic copy to their company by e-mail.
5-If said famous music trademarks are not registered in Brazil, then the holders of these trademarks should base their claim on
Well-known marks ( Article 6bis of Paris Convention: As far as I know Brazil is party to the Paris Convention since 1884, therefore Brazil is responsible for protecting well-known marks, even if they are not registered)
Trade names (Article 8 of Paris Convention: A trade name shall be protected in all the countries of the Union without the obligation of filing or registration, whether or not it forms part of a trademark.)
6- As a result, you should convince the holders of these famous music trademarks that they must file a trademark infringement action against said company and you may assist them in every stage by supplying evidences.
This method takes time, but it always works:)
