The National Institute of Industrial Property (INPI), through Resolution INPI P-297/2026, approved new Regulations for the Administrative Resolution of Oppositions against trademark applications.

The new regulations seek to streamline and simplify the procedure, mainly through the automation of proceedings and the consolidation of evidentiary proceedings.

Among the main changes is the elimination of the separate evidence stage. Documentary or instrumental evidence must be submitted by the parties when they expand upon the grounds of the opposition or respond to the opposition, as applicable.

These regulations will apply to oppositions filed against new trademark applications filed on or after March 1, 2026, inclusive. On the other hand, oppositions filed against new trademark applications submitted on or before February 28, 2026, inclusive, will continue to be processed through completion under the previous procedure and the rules, stages, deadlines, and requirements applicable to them.
