A European consumer goods brand discovers that a nearly identical mark has been actively used in Hungary for over two years – covering the same goods category and reaching the same retail channels. The window for straightforward administrative remedies has not closed, but every additional month of inaction allows the infringing mark to accumulate local goodwill. Acting decisively at this stage is not optional; it is the difference between recovering full market position and accepting a permanent compromise.
This matter involved a cross-border trademark infringement claim filed before Hungarian intellectual property authorities, combining opposition proceedings with a parallel civil enforcement action. The client held a registered EU trade mark with priority over the contested sign, and Hungarian intellectual property legislation provided a clear basis for both the administrative and judicial tracks. Resolution required coordinating two concurrent procedures across a period of approximately fourteen months.
This case study sets out the client profile, the strategic choices made, the key milestones and complications encountered, and the transferable lessons applicable to similar cross-border disputes in Hungary and the wider EU.
Client profile and the challenge
The client was a mid-sized consumer goods company headquartered in Western Europe, operating across multiple EU markets. Its core brand had been registered as an EU trade mark for several years. The mark covered goods within a specific Nice classification category – a classification system used internationally to group goods and services for trademark application purposes.
The problem surfaced during a routine trademark watch report. A Hungarian entity had filed a national trademark application for a sign that was visually and phonetically similar to the client's EU mark. The application had progressed through the Magyar Szabadalmi Hivatal (Hungarian Intellectual Property Office) without triggering an automatic block, because the Office does not examine relative grounds on its own initiative under Hungarian intellectual property legislation. That task falls to the senior mark holder.
The client faced two compounding risks. First, if the Hungarian application proceeded to registration, cancellation proceedings would be required – a slower and costlier route than opposition. Second, the local entity had already begun using the contested sign in commerce, meaning every passing week deepened market confusion and potentially strengthened the third party's position in any future use-based argument.

Legal strategy and rationale
The team identified three available instruments. The first was an opposition filed with the Hungarian Intellectual Property Office to block the pending trademark application before registration. The second was a civil infringement claim before Hungarian courts to obtain an injunction and damages for the period of unlicensed use already occurring. The third was a potential EU-level cancellation action, held in reserve if the national application had already converted to registration before the opposition deadline was reached.
The opposition track was selected as the primary vehicle. It offered a faster and more cost-proportionate route than litigation for the registration question. Critically, a successful opposition would prevent the opposing party from acquiring any registration – removing the strongest defensive argument available to an infringer. Simultaneous civil proceedings were launched to address the ongoing use and to preserve the client's right to damages during the administrative phase.
The decision to pursue both tracks concurrently rather than sequentially was deliberate. Waiting for the opposition result before filing civilly would have allowed additional months of infringing use to accumulate. Under Hungarian intellectual property legislation, the civil court was able to grant provisional injunctive relief on the basis of the EU mark alone, without waiting for the administrative outcome. That injunction was sought and obtained at an early stage, halting distribution of the infringing goods within Hungary.
The strategy also accounted for the cross-border dimension. The infringing entity had supply relationships in two other Central European markets. Coordinating the Hungarian action with parallel monitoring in those jurisdictions – while keeping the primary proceedings focused and efficient – required careful scoping.

Key milestones and complications encountered
The opposition was filed within the statutory window. The Hungarian Intellectual Property Office accepted the filing and notified the applicant, opening a cooling-off period during which settlement negotiations are encouraged. Those negotiations revealed a complication: the opposing entity argued that its use predated the client's awareness of the Hungarian market, and it produced commercial documents in support. This use-based argument required the client to prepare a detailed chronology of its own EU mark's priority date and territorial coverage.
The Office's examination of relative grounds required the client to demonstrate likelihood of confusion. This involved submitting evidence of visual and phonetic similarity, analysis of the relevant Nice classification goods, and a comparison of the marks' respective market positions. The IP registration record of the EU mark – confirmed through the EUIPO database – provided the anchor for the priority argument.
The provisional injunction in the civil proceedings presented its own complication. The opposing party challenged the injunction, arguing that the client had not demonstrated genuine use of the EU mark in Hungary. This is a recognised vulnerability in EU mark enforcement at national level: a mark registered at EU level but not actively used in a specific member state can face a non-use defence. The team countered by producing evidence of the mark's use in neighbouring markets and documenting the client's active distribution plans for Hungary. The court maintained the injunction, though it required a security deposit as a condition for continued interim relief.
Settlement negotiations resumed after the injunction was confirmed. The opposing party, now facing both an opposition and an injunction, agreed to withdraw its trademark application and cease use of the contested sign within Hungary. The civil proceedings were stayed by agreement, preserving the client's right to damages claims should any future breach occur. For comparison with a similar matter handled in another EU jurisdiction, the trademark dispute case study for Portugal illustrates how the strategic approach adapts across civil law systems.
Transferable lessons for cross-border trademark matters
Three principles from this matter apply directly to comparable cross-border IP disputes within the EU.
Act before registration, not after. Opposition proceedings – filed before a conflicting application reaches registration – are significantly faster and less expensive than post-registration cancellation. The cost and duration gap between the two routes is substantial. Any business holding EU or national marks should maintain an active trademark watch programme covering all jurisdictions where commercial activity is planned or ongoing. The moment a conflicting application appears, the opposition window defines the available strategy.
Secure interim relief early and document use. An EU trade mark provides broad territorial coverage, but enforcement at national level requires demonstrating either use or genuine market presence in the relevant jurisdiction. Injunctive relief can be obtained on the basis of an EU mark alone, but an opposing party will frequently raise a non-use challenge. Building and preserving evidence of use – sales data, distribution agreements, marketing materials, import records – is an ongoing obligation, not a pre-litigation task. Practitioners handling infringement claims in Hungary note that courts apply this requirement rigorously in interim proceedings.
Coordinate administrative and civil tracks from the outset. Waiting for an administrative outcome before filing civilly allows ongoing infringement to continue and can weaken a damages claim. Running both tracks in parallel maximises pressure, produces earlier injunctive relief, and often accelerates settlement. The coordination requires careful case management to avoid inconsistent positions, but the strategic benefit outweighs the additional complexity in most cross-border matters of this type.
