A European technology company discovered that a former distribution partner had filed a trademark application in Belgium covering the company's core brand name. The filing predated any formal termination notice. By the time the client sought legal advice, the IP registration was approaching final grant – and enforcement windows were narrowing.
Challenging a bad-faith trademark registration in Belgium requires initiating opposition proceedings before the relevant IP authority or pursuing a cancellation action through the courts. Supported by evidence that the applicant lacked genuine intent to use the mark and was aware of the original owner's prior rights. Belgian intellectual property legislation provides specific grounds for challenging registrations made in bad faith, and the process typically spans several months depending on the procedural route chosen. Securing interim protective measures can preserve the client's position while the principal challenge proceeds.
This case study outlines the strategy Ferraz & Whitmore applied, the complications encountered, and the lessons that translate directly to similar cross-border IP recovery matters.
Client profile and the challenge
The client was a mid-sized technology business headquartered outside Belgium, operating across several EU member states. Its brand had been in active commercial use for several years before the disputed filing occurred.
The former distribution partner had used its position to register the mark under a Nice classification (the international system for categorising goods and services in trademark applications) that closely mirrored the client's own product lines. The registration covered multiple classes, which widened the scope of potential harm.
The central challenge was timing. The opposition period under Belgian intellectual property legislation is strictly defined. Missing it shifts the matter from a relatively streamlined opposition process to a more resource-intensive cancellation action before the courts. The client came to us approximately three weeks before that deadline expired.
A secondary complication arose from the cross-border dimension. The client held rights in several jurisdictions but had not yet completed a formal trademark application in Belgium itself. This gap weakened the documentary foundation for the challenge and required immediate remediation in parallel with the opposition filing.
Legal strategy: rationale and sequence
The strategy rested on two simultaneous tracks. The first was an opposition filing on bad-faith grounds within the remaining window. The second was a protective filing of the client's own IP registration across the relevant Nice classes to establish a clear priority baseline going forward.
Bad-faith opposition proceedings in Belgium require the opposing party to demonstrate that the applicant had knowledge of the original owner's prior use and acted with intent to appropriate that goodwill. This is a higher evidential threshold than a simple likelihood-of-confusion argument. The team assembled commercial correspondence, distribution agreements, marketing materials, and invoices spanning the full commercial relationship – all of which established that the former partner had detailed knowledge of the brand and its market position.
The decision to pursue opposition rather than wait and file a cancellation action was deliberate. Opposition proceedings are handled administratively and move faster. A cancellation action before the Belgian courts, while available, would have extended the timeline by at least twelve to eighteen months and increased costs substantially. Speed mattered: the client was actively pursuing a funding round, and an unresolved IP dispute of this nature posed a material diligence risk.

Key milestones and complications encountered
The opposition was filed within the deadline, accompanied by a detailed evidentiary submission. Within six weeks of filing, the opposing party responded with a counter-claim alleging that the client had abandoned the mark in Belgium due to non-use. This introduced a parallel dispute that required separate documentation – specifically, evidence of genuine commercial use of the mark within the relevant territory during the preceding years.
Assembling that evidence across multiple jurisdictions took time. Belgian intellectual property legislation on non-use periods requires careful attention to territorial scope. Use of the mark in neighbouring EU states does not automatically satisfy the Belgian territorial requirement. The team worked with the client to identify Belgium-specific commercial activity: invoices issued to Belgian customers, trade press coverage, and website analytics showing Belgian user traffic.
A further complication arose mid-process when it became apparent that one class of goods in the contested trademark application had genuine ambiguity. the description used by the former partner overlapped with a category the client had never actively commercialised. The team made a tactical decision to narrow the scope of the opposition on that class rather than pursue an all-or-nothing position. Narrowing reduced the risk of a partial adverse finding that could have created unintended rights for the opposing party in that category.
The full opposition proceedings concluded within approximately nine months of the initial filing.

Transferable lessons for cross-border IP matters
File defensively before disputes arise. The single most significant vulnerability in this matter was the absence of a Belgian trademark registration at the time the former partner filed. An infringement claim is materially stronger when the claimant holds a registered right in the jurisdiction. Businesses operating through distribution partners in EU member states should conduct regular audits of their IP registration coverage across each territory. not only at the EU-wide level but at the national level where gaps may exist.
Timing is determinative in opposition proceedings. Belgium, like other EU jurisdictions, applies strict deadlines to the opposition window. Missing that window does not extinguish the right to challenge a bad-faith registration, but it shifts the matter to litigation – which is slower, more expensive, and less predictable. Monitoring third-party trademark applications in key markets through watch services is a cost-effective preventive measure that the majority of mid-sized businesses underutilise.
Bad-faith cases require documentary depth. A bad-faith ground in opposition proceedings is not self-proving. The evidentiary burden demands a coherent documentary record connecting the applicant to the original owner's prior use. Businesses entering distribution or agency relationships should ensure that contracts, correspondence, and operational records are retained systematically. In a bad-faith challenge, a commercial email thread from several years earlier can carry more weight than a formal legal declaration.
