A technology-driven consumer brand had spent several years building recognition across two EU markets. Then its team discovered a competitor was using a near-identical mark on overlapping goods in Ireland. goods that sat squarely within the same Nice classification (the international system for categorising goods and services in trademark applications). The window to act was narrowing. Every month of inaction allowed the competing mark to accumulate goodwill in the Irish market, reducing the leverage available to enforce rights and increasing the cost of any eventual remedy.
This matter involved a cross-border trademark infringement claim pursued through Irish intellectual property legislation and EUIPO proceedings. The client held a registered EU trademark covering relevant Nice classification categories, while the opposing party had filed a national Irish trademark application for a confusingly similar sign. The strategy combined opposition proceedings before the relevant registry with parallel infringement proceedings in Ireland, ultimately resolving the conflict before full trial.
This case study outlines the client profile, the strategic choices made, key milestones, the complications encountered, and three transferable lessons for businesses facing analogous cross-border IP disputes.
Client profile and the challenge
The client was a European technology company with operations across Ireland, Portugal, and the Netherlands. Its core product – a software-enabled consumer service – was registered under a distinctive word mark at the EUIPO level. The mark had been in active use for several years and covered clearly defined categories under intellectual property legislation governing trademark registration.
The challenge arose when the client's Irish distribution partner flagged a new entrant operating under a similar name and logo. The competitor had filed a national trademark application in Ireland, sought IP registration in overlapping service categories, and had already begun marketing activity. The confusing similarity was not merely visual. The marks shared phonetic and conceptual elements that created a genuine likelihood of association in the relevant consumer segment.
The client's immediate concern was market dilution. Secondary concerns included the risk that the Irish application, if granted, would harden the competitor's position and complicate any future EU-wide enforcement. For companies with cross-border brand exposure, the cost of delayed enforcement is rarely abstract. Lost market position is difficult to recover once a competing sign has been used openly for an extended period.
Our intellectual property practice in Ireland was engaged to assess the enforceability of the client's rights and design a response strategy.
Strategy chosen and rationale
The team identified two concurrent tracks. First, formal opposition proceedings were filed against the pending Irish trademark application before the relevant national registry. The opposition relied on the client's prior EU trademark rights, the similarity of the marks, and the identity of the covered goods and services under the applicable Nice classification categories. Under Irish intellectual property legislation, an EU trademark registration constitutes a valid earlier right for opposition purposes. This made the client's position technically strong from the outset.
Second, a formal letter before action was directed to the competitor, asserting infringement of the EU trademark and demanding cessation of use in Ireland. The letter was framed to open a negotiation channel while preserving the right to commence infringement proceedings before the Irish courts if the matter was not resolved.
The rationale for the dual-track approach was deliberate. Opposition proceedings alone address registration but not ongoing use. Infringement proceedings alone, without the opposition, would leave the competitor's application in place – potentially creating a parallel right that could complicate enforcement in later phases. Running both tracks in parallel applied pressure on both the legal and commercial fronts simultaneously.
For businesses operating across EU and national trademark systems, understanding how EUIPO rights interact with national proceedings is essential. Related considerations for technology-sector clients in Ireland – where brand and product identity increasingly intersect with platform and AI-related questions – are addressed in our AI and technology law practice in Ireland.
Key milestones and complications encountered
The opposition was filed within the statutory opposition period following publication of the Irish application. Evidence of the client's prior use and the strength of the EU trademark was assembled and submitted in support. The registry accepted the opposition as admissible and notified the applicant.
The first complication arose at the evidence stage. The competitor challenged the client's proof of genuine use of the EU trademark, arguing that the mark had not been used in a form that preserved its distinctive character. This is a standard defensive tactic in opposition proceedings. Additionally, it required the client to produce commercial documentation. invoices. Marketing materials. Additionally, web analytics. demonstrating consistent, bona fide use across multiple EU territories during the relevant period.
The second complication was geographic. Key witnesses with direct knowledge of the client's Irish market activity were based in the Netherlands. Coordinating their statements across jurisdictions added time to the evidence preparation phase.
Concurrent with the opposition, the competitor's legal representatives responded to the letter before action. They did not concede infringement but indicated a willingness to discuss commercial resolution. Negotiations extended over several weeks. The competitor ultimately agreed to rebrand its Irish operations, withdraw the trademark application, and refrain from using the contested sign in Ireland. The settlement was documented through a formal agreement that included a standstill provision and a reasonable transition timeline.
The matter resolved without full trial. The opposition proceedings were withdrawn following the settlement, and the competitor's application was removed from the register.

Transferable lessons for cross-border trademark matters
Act before registration crystallises. In this matter, the competitor's Irish application had not yet been granted when proceedings commenced. Opposition proceedings are significantly more cost-effective than post-registration cancellation actions. Once a mark is registered and has been used openly for an extended period, the legal burden shifts. Businesses with EU trademarks should monitor national filings in key markets on a routine basis. The Irish register, like other EU member state registries, publishes applications at the point of acceptance – which triggers the opposition window.
Use the prior rights architecture of EU trademark law. A registered EU trademark is a powerful instrument in Irish opposition and infringement proceedings. Under the relationship between EU intellectual property legislation and national Irish trademark law, EU registrations take effect as earlier rights capable of blocking conflicting national applications. Businesses that have invested in EU-level trademark application and IP registration across broad Nice classification categories hold a structurally stronger position in national disputes than those relying solely on national marks or unregistered rights.
Dual-track pressure produces faster resolution. The combination of opposition proceedings and a formal infringement claim created conditions for negotiated settlement. Neither track alone would have applied sufficient pressure across both the registration and commercial dimensions. Practitioners working on cross-border trademark matters consistently find that parallel proceedings – properly coordinated – tend to produce earlier resolution than sequential approaches. This is particularly relevant for technology businesses, where brand exposure spans multiple jurisdictions and delay directly affects revenue.
