A European consumer goods brand had built considerable recognition in its home market. Its entry into Mexico brought an unexpected obstacle: a local entity had filed a near-identical trademark application covering the same goods in the same Clasificación de Niza (Nice classification). Without prompt action, the client risked losing its ability to operate under its own name in one of Latin America's largest markets – and the window for intervention was narrowing.
This case study examines how a cross-border trademark dispute in Mexico was resolved through a structured enforcement strategy combining opposition proceedings before the Instituto Mexicano de la Propiedad Industrial (Mexican Institute of Industrial Property. Known as IMPI) and a parallel infringement claim. The client's IP registration rights were ultimately secured within approximately fourteen months. The matter illustrates how early procedural choices determine whether a foreign brand retains market access in Mexico.
The following sections cover the client profile, the strategy rationale, key milestones, complications encountered, and three transferable lessons for businesses facing comparable cross-border IP disputes.
Client profile and the challenge
The client was a mid-sized European company in the consumer goods sector, operating in several EU jurisdictions and beginning its expansion into Latin America. Its brand had been registered in its home country for several years. However, it had not filed a trademark application in Mexico prior to announcing its market entry publicly.
A local distributor – with whom preliminary commercial discussions had taken place – had registered a nearly identical mark in Mexico. The registration covered the same goods under the relevant Nice classification. The local party had proceeded to use the mark commercially, creating consumer confusion and blocking the client's own IP registration efforts through IMPI.
The client faced two simultaneous risks. First, if the local mark proceeded to full registration, the client would be unable to use its own brand name in Mexico without risk of an infringement claim being brought against it. Second, commercial momentum was being lost while the dispute remained unresolved. For a brand entering a new market, that lost time translates directly into lost revenue and eroded first-mover positioning.
Our team at Ferraz & Whitmore was engaged to design and execute a strategy that would address both the administrative and civil dimensions of the dispute. Our intellectual property practice in Mexico provided the procedural and substantive foundation for the approach described below.
Strategy chosen and key milestones
The core of the strategy rested on two coordinated tracks. The first was an opposition proceeding before IMPI. Mexican intellectual property legislation allows a party with prior rights – including rights established through use or registration in another jurisdiction – to challenge a pending trademark application before it achieves full registration status. Filing the opposition within the statutory window was the immediate priority.
The second track was a civil infringement claim, filed in parallel. This served two purposes. It created legal pressure on the local party and put commercial partners in Mexico on notice that the disputed mark was subject to challenge. It also preserved the client's options in the event the IMPI opposition did not succeed within the anticipated timeframe.
The key milestones proceeded as follows. Within the first two weeks, the opposition was filed with IMPI, supported by evidence of prior use, the client's existing registrations in the EU, and documentation of the commercial relationship with the local distributor. Within six weeks, the civil infringement claim was formally initiated. By the fifth month, IMPI issued a preliminary procedural decision confirming the admissibility of the opposition. By month ten, the civil proceedings had produced an interim measure restricting the local party's active use of the contested mark in trade materials. By month fourteen, IMPI ruled in the client's favour, rejecting the local party's trademark application. The civil matter was subsequently resolved through a negotiated settlement.
For businesses facing analogous disputes in the United States, the comparable enforcement dynamics in U.S. trademark proceedings offer useful context on how opposition and infringement strategies interact in common law systems.
Complications encountered and how they were addressed
Three complications arose during the proceedings that required strategic adjustment.
The first was evidentiary. IMPI's assessment of prior rights in cross-border matters requires documented proof of use or registration that meets specific formal standards under Mexican intellectual property legislation. The client's EU-based certificates needed notarisation, apostille, and certified translation before they could be submitted. Delays in obtaining these documents from two different EU member states created a near-deadline situation. The team coordinated directly with local notarial authorities to accelerate the process without compromising document integrity.
The second complication arose from the local party's counter-arguments. The opposing party claimed that the client's mark, as used in the EU, had a distinct stylised element that rendered it insufficiently similar to the mark filed in Mexico. This argument required a detailed comparative analysis of the marks across visual, phonetic, and conceptual dimensions – a standard applied under IMPI adjudication practice. The submission addressed each dimension methodically, drawing on established IMPI decision patterns in similar Nice classification disputes.
The third complication was procedural timing in the civil track. Mexican civil procedure rules permit injunctive-type interim measures, but the threshold for obtaining them requires demonstrating both likelihood of success and irreparable harm. Establishing irreparable harm for a brand that had not yet formally launched in Mexico required a forward-looking commercial analysis rather than a record of actual losses. This was presented through market entry documentation, signed distribution agreements, and evidence of consumer recognition surveys conducted in border regions where the brand had limited prior visibility.

Transferable lessons for cross-border trademark matters
Lesson one: File early, regardless of launch timing. The single most consequential decision in this matter was not made in the proceedings – it was made, or rather deferred, before they began. The client's failure to file a trademark application in Mexico prior to announcing its market entry created the vulnerability that the local party exploited. Mexican intellectual property legislation, like most civil law systems in Latin America, operates on a first-to-file basis. Prior use in another jurisdiction confers some rights, but asserting them is costly and uncertain compared to holding a registered mark. The lesson is simple: IP registration in target markets should precede public commercial activity, not follow it.
Lesson two: Opposition proceedings and civil litigation are not alternatives – they are complements. A purely administrative strategy through IMPI carries procedural risk. Timelines can extend, and outcomes are not certain. Running a parallel civil track, even at modest intensity, creates leverage. It signals resolve to the opposing party, opens the door to interim relief, and may accelerate settlement. The combination proved decisive here: the interim measure obtained in the civil proceedings effectively neutralised the local party's commercial use of the mark while IMPI completed its assessment.
Lesson three: Evidence preparation is the longest lead-time item. In cross-border disputes before IMPI, the strength of a party's position depends heavily on the quality and admissibility of its documentary evidence. Foreign certificates, translations, and apostilles require significant preparation time. Parties that underestimate this risk find themselves filing incomplete records or missing procedural deadlines. Engaging a lawyer in Mexico with cross-border experience – specifically one familiar with IMPI's evidentiary standards – at the earliest possible stage reduces this risk materially. A law firm in Mexico that regularly handles opposition proceedings will have established workflows for the documentary preparation phase that a generalist adviser may lack.
