A European technology business had spent several years building brand recognition across multiple markets. When a competitor in Norway began trading under a name that was nearly identical. and in overlapping Nice classification categories. the client faced a clear choice: act decisively or watch the IP registration window close permanently.
This case study examines a cross-border trademark dispute resolved in Norway, involving an infringement claim against a locally registered mark. The matter required coordinated action under Norwegian intellectual property legislation and the broader European IP registration system. Proceedings were concluded within approximately fourteen months of initial instruction.
The following account sets out the client profile, the legal strategy adopted, key milestones in the proceedings, complications encountered, and three transferable lessons for businesses facing comparable cross-border IP conflicts.
Client profile and the challenge they faced
The client was a mid-sized technology company headquartered outside Norway. It held a registered trademark in its home jurisdiction and across several EU member states. It had not, however, completed a direct trademark application in Norway – a non-EU country governed by its own intellectual property legislation under the Patentstyret (Norwegian Industrial Property Office) system.
The competitor had filed a trademark application in Norway approximately eight months before the client engaged our firm. The application covered goods and services within the same Nice classification classes as the client's core products. Publication had occurred and the opposition window was still open – though barely. Without prompt action, the competitor's mark would proceed to registration unchallenged. Once registered, reversing that position would require considerably more time, cost, and procedural effort.
The client's business in Norway was growing. Losing the right to use its own mark in that market – or facing an infringement claim from a newly registered holder – would have had direct commercial consequences. The situation demanded immediate assessment and a structured enforcement strategy.

Strategy: opposition proceedings as the primary instrument
The team conducted an initial assessment within the first week of instruction. Three paths were available: file opposition proceedings before the Patentstyret, initiate a direct infringement claim before the Norwegian courts, or negotiate a coexistence agreement with the competitor.
Litigation was assessed as premature. The competitor's mark had not yet reached registration. Pursuing court proceedings at that stage would have been procedurally inefficient and disproportionate to the risk level. A coexistence agreement was considered but set aside as a parallel option – the client's commercial interests required exclusivity, not shared use.
Opposition proceedings were the correct primary instrument. Under Norwegian intellectual property legislation, a party with prior rights may oppose a pending trademark application within a defined period following publication. The client's earlier registrations in its home jurisdiction and across EU member states provided a strong evidentiary foundation for a priority argument. The key question was whether those prior rights would be recognised as sufficient grounds under Norwegian law.
The strategy rested on three pillars. First, establish prior use and prior registration as grounds for the opposition. Second, demonstrate the likelihood of confusion arising from the visual and conceptual similarity of the marks. Third, show overlap in the relevant Nice classification categories to reinforce the likelihood of confusion argument.
The opposition filing was submitted within the statutory period. Supporting documentation included certified copies of the client's existing registrations, evidence of market presence and prior use, and a detailed comparison of the competing marks across the relevant classification categories.
Key milestones and complications encountered
The Patentstyret acknowledged receipt and assigned the matter for examination. The procedural timeline from filing to first substantive decision ran approximately nine months. During that period, the competitor filed a detailed response contesting the opposition on two grounds: that the marks were sufficiently distinct, and that the client lacked genuine use in the Norwegian market.
The genuine use challenge was the more serious complication. Norwegian intellectual property legislation requires that a mark be put to genuine commercial use in the relevant territory to sustain enforcement rights. The client had conducted business in Norway through a distribution arrangement rather than a direct presence. The competitor argued this was insufficient to establish genuine use.
The response required documentary evidence of the distribution activity: invoices addressed to Norwegian customers, marketing materials in Norwegian, and correspondence demonstrating the client's brand was actively promoted under the disputed mark. Assembling this evidence retrospectively was time-consuming. Several documents required translation and notarisation to meet evidentiary standards.
A secondary complication arose from the classification overlap. The competitor argued that certain goods in the relevant Nice classification categories were distinct enough to avoid confusion. The team prepared a detailed comparative analysis of the goods and services, referencing the classification guidance applied by the Patentstyret and the broader European IP registration practice under the EUIPO system. which. While not binding in Norway, is frequently consulted as persuasive authority.
The Patentstyret ultimately upheld the opposition. The competitor's trademark application was refused registration. The decision rested primarily on the likelihood of confusion, supported by the client's demonstrated prior rights and the documented evidence of genuine use through the distribution channel.

Transferable lessons for cross-border trademark matters
Lesson one: non-EU jurisdictions require independent registration. A registered mark within the EU does not automatically extend protection to Norway, Switzerland, or other non-EU European states. Businesses expanding into these markets frequently assume their EU-wide registrations provide sufficient coverage. They do not. A direct trademark application – or an international application through the Madrid System designating Norway – is necessary to secure enforceable rights on Norwegian territory. Delaying this step creates the gap that a competitor can exploit.
Lesson two: opposition proceedings are time-critical. The window to file opposition proceedings after a competing mark is published is fixed and short. Missing it does not end the dispute – but it changes its character significantly. Post-registration challenges require a cancellation action, which carries a higher evidentiary burden and longer proceedings. Acting within the opposition window is almost always more cost-effective than pursuing cancellation after the fact.
Lesson three: genuine use evidence must be maintained proactively. Businesses operating in foreign markets through intermediaries – distributors, agents, licensees – are particularly exposed to genuine use challenges. Courts and IP offices in Norway and across Europe apply a substantive test: use must be real, commercial, and traceable to the mark holder. Maintaining organised records of invoices, marketing materials, and distribution correspondence in each jurisdiction is not merely good practice. It is the evidentiary foundation on which enforcement rights depend.
