A European consumer goods company arrived in Brazil ready to launch. Its brand had traded across five countries for over a decade. Then it discovered that a local entity had already filed a trademark application for an identical mark. under the same Nice classification (an internationally standardised system for categorising goods and services in trademark applications). months before the European company had begun its Brazil entry process. Market entry stalled. Distribution agreements were suspended. Every week without resolution meant lost revenue and a competitor consolidating brand recognition in the client's name.
IP portfolio recovery in Brazil centres on challenging a bad-faith IP registration before the Instituto Nacional da Propriedade Industrial (INPI, Brazil's national industrial property office). The process involves administrative opposition proceedings and, where necessary, nullity actions before the federal courts. Resolution typically spans one to three years depending on complexity and whether litigation is required.
This case study covers the client's situation, the legal strategy chosen, key milestones, complications that arose, and three transferable lessons for international businesses facing similar IP registration challenges in Brazil.
Client profile and the challenge presented
The client was a mid-sized European manufacturer with registered trademarks in the EU, the United Kingdom, and two Latin American markets. Brazil represented its single largest growth target. The company had invested in packaging adaptation, regulatory compliance, and local distributor negotiations before discovering the conflicting registration.
The local entity holding the Brazilian trademark application had no commercial history in the relevant product category. It operated in an unrelated sector and had filed applications across multiple Nice classifications – a pattern consistent with what Brazilian intellectual property legislation describes as bad-faith filing behaviour. The registrant appeared to be a trademark troll: an entity that files marks in anticipation of foreign brand owners entering the market, with the intention of extracting a settlement.
The client faced a binary choice. It could negotiate a purchase of the conflicting application, accepting the troll's terms and setting a precedent for future leverage. Or it could challenge the registration directly through opposition proceedings and, if necessary, a nullity action. The second path carried risk – Brazilian IP proceedings move slowly – but it preserved the client's commercial position and deterred similar conduct in other categories.
Legal strategy: opposition, evidence, and parallel pressure
The strategy rested on three simultaneous tracks. First, the team filed a formal opposition with the INPI before the application reached the publication-and-grant stage. The opposition relied on the client's prior use of the mark internationally, supported by documentation showing the mark had acquired reputation in markets adjacent to Brazil before the local filing date.
Second, counsel prepared a bad-faith nullity petition as a contingency. Brazilian intellectual property legislation permits the filing of a nullity action before the INPI or the federal courts when a registration was obtained through conduct that violates good faith principles. The petition documented the registrant's filing pattern across multiple Nice classifications and product categories – none related to its declared business activity.
Third, the team sent a formal cease-and-desist letter to the registrant's known commercial contacts, signalling that an infringement claim was being prepared if the registrant attempted to use the mark commercially. This step was calculated to impose reputational cost on the registrant without initiating litigation prematurely.

Key milestones and complications encountered
The opposition was filed within the statutory window. The INPI acknowledged receipt and opened a response period for the registrant. The registrant submitted a defence arguing priority of filing date and disputing the client's claimed international reputation.
The first complication arose at the evidence stage. The client's international trademark registrations predated the Brazilian filing, but Brazilian intellectual property legislation does not automatically accord priority based on foreign registrations alone. The team had to document market presence. through export invoices, distributor correspondence, press coverage, and trade fair participation – to establish that the mark had become associated with the client in the relevant commercial context.
The second complication was administrative delay. INPI proceedings in Brazil can extend beyond expected timelines. The opposition examination took several months longer than projected. During this period, the registrant filed a parallel trademark application in a related Nice classification – an attempt to broaden its position before the original opposition was resolved.
The team responded by filing a second opposition against the parallel application and escalating the bad-faith nullity argument to encompass both filings. The pattern of conduct across multiple applications strengthened the bad-faith characterisation under Brazilian intellectual property legislation.
Businesses facing comparable cross-border IP challenges. particularly those involving technology-adjacent brands. may also find relevant strategic context in the firm's work on AI and technology law matters in Brazil. There. Overlapping IP and regulatory questions frequently arise.
The registrant ultimately withdrew both applications before the INPI issued its examination decision. The withdrawal came after the second opposition was filed and after the bad-faith nullity petition was formally served. The client then filed its own trademark application, which advanced through examination without opposition.
Transferable lessons for cross-border IP matters
File early, even before market entry. The client's delay in filing a Brazilian trademark application created the window the troll exploited. Brazilian intellectual property legislation operates on a first-to-file principle. A foreign company's prior international use provides grounds for challenge, but it does not substitute for a local filing. Engaging a lawyer in Brazil to file defensively – before public announcements, distributor agreements, or regulatory submissions – eliminates the exposure entirely. Engaging a law firm in Brazil with cross-border IP experience ensures that Nice classification decisions align with the company's commercial roadmap, not just the minimum required for the immediate launch category.
Document international reputation continuously. The evidentiary burden in a bad-faith opposition or nullity action falls on the challenger. The client had the underlying facts – genuine prior use, established reputation, international registrations – but the documentation was dispersed across business units. Assembling the evidence package required weeks of internal coordination. Companies with active cross-border expansion programmes benefit from maintaining a centralised IP evidence repository: export records, distributor agreements, marketing materials, and press coverage organised by jurisdiction and date.
Use the parallel pressure track deliberately. The cease-and-desist letter to the registrant's commercial contacts accelerated the matter. Trademark trolls operate as commercial actors. When the cost of holding a challenged registration rises – through legal exposure, reputational risk among potential buyers, and the prospect of an infringement claim – many registrants reassess the economics of continued opposition. This does not mean threatening litigation without intent to follow through. It means structuring communications so that the registrant understands the full cost of the position it has taken. Combined with a well-documented INPI opposition, this approach can resolve matters before a federal court nullity action becomes necessary.
