Relevance of Brazil

Brazil is among the ten largest world economies and plays an important role as a commercial partner in the MERCOSUR and in the international scenario.

The country is a vital market for those willing to develop and maintain a global intellectual property portfolio.

Failing to accurately protect intellectual property rights may prevent a company from obtaining the full commercial value of its assets and in many cases getting involved in lengthy and expensive litigation. With a modern law enacted in 1997 and a strong legal system, Brazil provides effective legal tools for those seeking protection for their intellectual property assets.

Brazil is a member of the TRIPS, Paris Convention for the Protection of Industrial Property, Patent Cooperation Treaty (PCT), Berne Convention for the Protection of Literary and Artistic Works, and Madrid Agreement for the Repression of False or Deceptive Indications of Source on Goods.
