The mark is one of the most valuable properties of your Company.  It is through mark that your clients will identify you and the consumers will choose your products or services. The mark is the sign utilized to identify and distinguish a product or a service. The right on the mark in Brazil is acquired through its registration with the competent Administration authority.  The registration of a trademark is of great importance since provided it is registered, no other company in Brazil, dedicated to the same field of activity, may use it without your express permission.


Care with the trademark begins with obtaining its registration. After the registration is granted, it is necessary to keep it in force by renewing it every 10 years.    During the whole validity period of the registration it is necessary to stay alert in order to prevent the registration of an identical or similar trademark, one that reproduces it even partially or with an addition, or the occurrence of imitations that may confound the consumer, leading him to buy the good of a competitor while he thinks it is your good or, even, leading him to associate trademarks of others with yours.  Our office takes charge of the registration prosecution of your trademark, from the moment of your choice, when, through the analyses of possible priorities, it is verified the registrability of the application.   After that, we take charge of all proceedings required to obtain the actual registration of the feasible trademark. After the grant of the registration, we take care of the maintenance and defense of your trademark.



The letters patent entitles its owner the right to explore, with exclusivity, the object of the invention, and to impede others from producing, commercializing or importing the object of the patent, while it is in force, without the owner’s permission.   The patent of invention is in force for a twenty (20)-year term counted as of the filing date of the application and the appropriate moment for applying for a patent is soon after the conclusion of the invention, even before its disclosure.


The care of your patent of invention or utility model does not end upon obtaining the Letters Patent.  It is necessary, as of the beginning of the third year, counting from the filing date, to attend to the payment of the yearly renewal fee.  In addition, a permanent monitoring is essential in order that others do not attempt to patent something similar or something based on your invention and also to prevent others from reproducing the object of your patent or in case this happens, proper remedies should be adopted.
