A European consumer goods company had spent years building brand equity in its home market. When it moved into Brazil. It discovered a third party had already filed a trademark application for a nearly identical sign. covering overlapping product categories under the same Nice classification (the international system for categorising goods and services in trademark applications). Every month that passed without action deepened the risk of losing exclusive rights to the brand in one of Latin America's largest commercial markets.
This matter required a two-track enforcement strategy in Brazil: parallel opposition proceedings before the Instituto Nacional da Propriedade Industrial (INPI, Brazil's national IP registry) and a civil infringement claim before the federal courts. The combined approach preserved the client's priority position while creating direct commercial pressure on the third-party registrant. Resolution was achieved within approximately 30 months from first instruction.
This case study sets out the client's situation, the legal strategy selected, the key milestones and complications encountered, and three transferable lessons for businesses facing similar cross-border IP registration conflicts.
Client profile and the challenge
The client was a mid-sized European manufacturer of personal care products operating across several civil law jurisdictions. It held trademark registrations in the EU and in a number of other markets but had delayed its Brazilian IP registration application by approximately 18 months due to internal budget cycles.
During that window, a domestic Brazilian company – operating in overlapping product segments – had filed for registration of a sign that shared the client's word element and a broadly similar colour scheme. The filing covered multiple classes under the Nice classification system, including the classes most commercially critical to the client's planned Brazilian launch.
The challenge had two dimensions. First, Brazil operates a first-to-file system under its intellectual property legislation. Prior use abroad does not automatically confer priority. Second, the domestic registrant had not yet been granted registration; the application was still pending at INPI. That procedural window was decisive. It meant opposition proceedings were still available – but the deadline was measured in weeks, not months.
For cross-border IP registration strategy in Brazil, the firm's intellectual property practice in Brazil covers the full spectrum from filing through enforcement.
Legal strategy and rationale
The team selected a dual-track approach from the outset. Track one was an administrative opposition filed at INPI, challenging the pending trademark application on the grounds of likelihood of confusion and the client's well-known mark status in foreign markets. Track two was a civil infringement claim filed in the federal courts, targeting the third party's actual commercial use of the contested sign in the Brazilian market. conduct that had already begun ahead of registration.
The rationale for running both tracks simultaneously was deliberate. Administrative proceedings at INPI are thorough but slow; decisions often extend beyond 24 months. A civil claim, by contrast, can yield interim injunctive relief within weeks if the evidentiary threshold is met. The injunction, if granted, would interrupt the third party's commercial activities and alter the negotiating dynamic considerably.
Supporting evidence was assembled in three categories. The first was documentary proof of the client's prior use and registration in other jurisdictions, establishing the mark's international reputation. The second was consumer survey evidence commissioned in Brazil, demonstrating actual confusion risk in the relevant market. The third was commercial intelligence on the third party's use – specifically, promotional materials and distribution records showing active exploitation of the contested sign before any registration had been granted.
This evidence base served both tracks. At INPI, it supported the opposition on well-known mark grounds. Before the federal courts, it underpinned the infringement claim and the application for interim measures. The dual-track design meant that even if one route encountered procedural delays, the other continued to generate pressure.

Key milestones and complications
The opposition filing at INPI was submitted within the statutory window – approximately 60 days from the publication of the third party's application in the official gazette. Missing this deadline would have foreclosed the administrative route entirely. Meeting it required assembling certified translations of foreign registration certificates and notarised evidence packages within three weeks of instruction.
The federal court claim was filed shortly thereafter. An application for an interim injunction was presented on the basis of the fumus boni iuris (appearance of legal right) and periculum in mora (risk of harm from delay) standards under Brazilian civil procedure rules. The court granted a preliminary injunction within approximately six weeks of filing. This halted the third party's use of the contested sign in commercial channels pending a full hearing.
Two complications arose during the proceedings. The first was a counterclaim by the third party alleging that the client's own filing. submitted after the third party's application. was opportunistic and that the client lacked sufficient commercial presence in Brazil to assert well-known mark status domestically. This required supplementary evidence of the client's market activities, including evidence of parallel import volumes predating the dispute. The second complication was a procedural objection at INPI relating to the classification of goods in the client's opposition filing. A minor discrepancy between the Nice classification headings used in the opposition and those in the underlying foreign registrations required a formal clarification submission, causing a delay of approximately three months.
Despite these complications, the INPI opposition remained on track. The third party, facing both an active injunction and a pending administrative challenge, entered into settlement negotiations approximately 20 months into the proceedings.
For a comparable enforcement matter in a common law context, the firm's case study on trademark dispute enforcement in the United States illustrates how strategy differs across legal systems.
Transferable lessons
Three lessons emerge from this matter that apply broadly to cross-border trademark disputes involving Brazilian proceedings.
Lesson one: the opposition window is not negotiable. Brazil's IP registration system publishes pending applications in the official gazette, triggering a fixed opposition period. Businesses that monitor competitor filings in key markets – and instruct local counsel promptly – retain the ability to contest problematic applications at the administrative level. Those that act late lose this option entirely and are left with costlier and slower court-based remedies only.
Lesson two: civil and administrative tracks are complementary, not alternatives. Many international clients assume that filing an opposition at INPI is sufficient. In practice, administrative proceedings alone rarely create sufficient commercial pressure to bring the opposing party to the table. A parallel civil claim – particularly one that yields interim injunctive relief – changes the economics of the dispute for the opposing party. The combination of both tracks consistently produces faster resolution than either alone.
Lesson three: Nice classification precision matters from the first filing. The classification of goods and services must be consistent across all documents submitted in opposition proceedings. the foreign registrations. The opposition brief, and any supporting exhibits. Even minor descriptive variations between classification headings can trigger procedural objections. This is a technical but consequential detail. A lawyer in Brazil with trademark prosecution experience will identify these risks before filing, not after a formal objection has caused delay.
