Belgium does not run its own national trademark register. For a Belgian business, "national" protection means a Benelux trademark.
One mark for three countries
Belgium, the Netherlands and Luxembourg pool their trademark system in the Benelux Office for Intellectual Property (BOIP). A single Benelux filing protects the mark across all three — there is no Belgium-only registration. Applications can be made in the region’s working languages.
Scaling up: EU and beyond
For protection throughout the EU, the EU trade mark (EUTM) via the EUIPO is the one-stop option; the Madrid Protocol extends a mark to non-EU markets.
Process and term
You file by class under the Nice Classification; BOIP checks absolute grounds, publishes, and allows an opposition by earlier-rights holders. Protection lasts ten years, renewable.
For foreign brand owners
If your market is only Belgium, you still register the whole of Benelux — worth weighing against an EUTM. A verified Belgian colleague can advise the scope and file it.
