A European software company enters a new Central European market – only to discover that a local reseller has already filed a trademark application covering its brand name in Hungary. The registration was filed months before the company formalised its own IP strategy in the region. Blocking it could take a year or more. Not acting at all means ceding brand control in a jurisdiction the company has chosen as a growth market.
IP portfolio recovery in Hungary involves challenging a trademark or other IP registration that was filed without the genuine owner's consent. typically through opposition proceedings or a cancellation action before the Szellemi Tulajdon Nemzeti Hivatala (Hungarian Intellectual Property Office, HIPO). The primary ground for challenge is bad faith at the time of filing, supported by evidence of prior use or prior knowledge. Proceedings before HIPO typically span six to eighteen months, depending on procedural complexity and whether the matter escalates to appeal.
This case study outlines how Ferraz &. Whitmore approached such a matter: the client's situation, the legal strategy selected, key milestones. Complications that arose along the way. Additionally, three transferable lessons for businesses facing comparable challenges across Central and Eastern Europe.
Client profile and the challenge
The client was a mid-sized technology company headquartered in Western Europe. It had built a recognised brand in its home market over several years. When it began expanding eastward, it relied initially on a distribution agreement with a Hungarian reseller.
That relationship broke down. Shortly before the formal termination, the reseller filed a trademark application at HIPO covering the client's core brand identifier across several Nice classification classes. including those directly relevant to its software products and professional services. The application had already passed the publication stage. The client had approximately sixty days from the date of publication to file opposition proceedings.
The core challenge was twofold. First, the client had no prior Hungarian trademark registration of its own. Its EU-wide IP registration existed, but its geographic scope and priority date required careful analysis. Second, the reseller's filing was tactically sophisticated: it covered not only the primary mark but also a stylised variant, reducing the client's room to operate under an alternative branding approach.

Legal strategy: opposition and bad-faith cancellation in parallel
The team identified two concurrent legal instruments available under Hungarian intellectual property legislation and the EU trademark regime.
The first was a formal opposition to the pending trademark application at HIPO. This was time-critical: the opposition window was already running. The grounds relied on the client's earlier EU trademark registration and demonstrated prior use in markets geographically proximate to Hungary. Opposition proceedings in Hungary follow a structured written procedure. Both parties submit observations; HIPO issues a decision. The process typically concludes within eight to twelve months at first instance.
The second instrument was a bad-faith cancellation action. Under Hungarian intellectual property legislation, a registration – or a pending application – may be challenged on the basis that the applicant acted in bad faith at the time of filing. Bad faith in this context means the applicant had knowledge of the genuine owner's prior rights and filed with the intention of exploiting or blocking them. The evidentiary threshold is substantive. Courts and HIPO expect documentary evidence of the prior relationship, communications demonstrating knowledge, and a chronological record establishing when that knowledge arose.
The team assembled a file of correspondence between the client and the reseller spanning several years. This included product delivery records, co-branded marketing materials, and internal emails in which the reseller expressly referenced the client's brand. That evidence formed the backbone of the bad-faith argument.
Running the opposition and the cancellation action in parallel carried a procedural rationale: if the opposition succeeded, the application would be refused. If the application had already proceeded to registration before a decision was reached, the cancellation action would remain the operative remedy. Pursuing both tracks simultaneously avoided the risk of losing the opposition window while waiting for a cancellation outcome.
Key milestones and complications
The opposition was filed within the statutory deadline. HIPO acknowledged the filing and set an initial response period for the applicant. The reseller contested the opposition on procedural grounds, arguing that the client's EU trademark registration did not establish sufficient reputation in Hungary specifically. This is a recognised line of argument under Hungarian practice: the domestic effects of an EU registration are acknowledged, but evidence of actual commercial presence or consumer recognition in Hungary can strengthen the position considerably.
The first significant complication arose at this stage. The client's commercial footprint in Hungary at the time of the reseller's filing was limited. Most of its documented activity had taken place through the reseller itself – meaning the reseller had, paradoxically, contributed to building the very brand it was now attempting to capture. The team reoriented the evidentiary file to emphasise this dynamic. Hungarian intellectual property legislation addresses situations where a former business partner exploits brand familiarity acquired through the commercial relationship. This reframing proved important.
A second complication was the classification coverage of the disputed application. The reseller had filed across multiple Nice classification classes, some of which the client did not actively use. Hungarian opposition proceedings allow the opponent to challenge the application in full or in part. A partial challenge – limited to the classes where genuine conflict existed – carried lower evidentiary burden but left residual exposure in peripheral classes. The decision was made to challenge the full application, accepting the higher burden in exchange for comprehensive recovery.
HIPO issued a decision upholding the opposition in the contested classes. The applicant appealed. The appeal prolonged the matter by approximately six months. The bad-faith cancellation action, filed concurrently, was still pending at the time of the appeal decision. The appeal body affirmed the opposition outcome. The cancellation action was subsequently withdrawn as moot, given that the application had been refused in full.

Transferable lessons for cross-border IP matters
File early, across all relevant jurisdictions. The single most consequential factor in this matter was the client's delay in registering its mark at the national level in Central European markets. An EU trademark registration provides a foundation, but national filings add a layer of direct protection and simplify opposition standing before domestic IP offices. In markets where distribution agreements are in place, filing should occur before – not after – the commercial relationship is established.
Treat the distribution agreement as an IP instrument. A well-drafted distribution or reseller agreement should contain explicit provisions restricting the counterparty from filing any trademark application or domain registration that incorporates the licensor's marks. It should also include an obligation to cooperate in IP registration and, upon termination, to transfer any inadvertently held registrations. Absent such clauses, the licensor's only recourse is litigation – which is slower, costlier, and less certain.
Parallel proceedings carry strategic value. Running an opposition and a cancellation action simultaneously increases procedural resilience. If one track is delayed or fails on technical grounds, the other remains operative. This is particularly relevant in jurisdictions where procedural timelines are difficult to predict. The additional cost of dual proceedings is generally modest relative to the commercial exposure of losing brand control in a growth market.
