Proving Acquired Distinctiveness in Benelux: Why the Bar Is So High

In the Benelux trademark system, it is possible in theory to register a descriptive trademark if it has become distinctive through use. In practice, however, the standard for proving acquired distinctiveness in Benelux is exceptionally high.

The key reason is the unitary nature of Benelux trademarks: distinctiveness must be proven across the entire Benelux region, not just in one country.

1. What is “acquired distinctiveness”?

Acquired distinctiveness means that a trademark which was originally descriptive or non-distinctive has, through use, come to be recognized by consumers as identifying a single commercial source.

Instead of describing the goods or services, the mark now functions as a brand in the minds of the relevant public.

This concept exists to allow businesses to protect signs that have gained real marketplace recognition over time, despite their descriptive origins.

2. Why acquired distinctiveness matters in Benelux

Benelux trademark law allows descriptive marks to be registered only if the applicant can prove that the mark has acquired distinctiveness through use.

However, because a Benelux trademark is a unitary right, acquired distinctiveness must exist for the entire Benelux territory.

This makes Benelux significantly stricter than systems where national registrations can be pursued country by country.

3. The critical rule: all three countries must be covered

To succeed, the applicant must demonstrate consumer recognition in:

• Belgium
• The Netherlands
• Luxembourg

Proving acquired distinctiveness in only one country—such as the Netherlands—is not sufficient.

If the evidence shows that consumers in Belgium or Luxembourg do not recognize the mark as a brand, the application will fail for the entire Benelux region.

4. Why evidence from one country is not enough

Applicants often assume that strong evidence from the Netherlands can carry the application. This assumption is incorrect.

Because the Benelux trademark is indivisible:

• Distinctiveness must exist across the whole region
• Evidence must cover different consumer markets and languages
• Gaps in geographic coverage are fatal to the claim

Even overwhelming recognition in one country cannot compensate for lack of recognition in another.

5. What kind of evidence is required?

The burden of proof for acquired distinctiveness in Benelux is high and evidence must be strong, specific, and geographically complete.

Typical evidence includes:

• Market surveys covering all three Benelux countries
• Sales figures broken down by country
• Advertising and marketing expenditures per country
• Length and intensity of use in each territory
• Examples of media coverage and consumer recognition

General or aggregated EU-wide evidence is usually insufficient unless it clearly demonstrates recognition in each Benelux country.

6. Language and perception challenges

Benelux is multilingual, and consumer perception may differ across languages and regions.

This means:

• A mark may be understood descriptively in one language but not another
• Recognition must be proven among the relevant public in each country
• Evidence must reflect local market realities

These linguistic and cultural differences further increase the difficulty of proving acquired distinctiveness.

7. Why acquired distinctiveness claims often fail

In practice, many Benelux applications relying on acquired distinctiveness are refused because:

• Evidence is limited to one or two countries
• Sales or marketing presence is uneven across the region
• Consumer surveys do not cover all territories
• The mark remains descriptive to a significant portion of the public

The standard is applied strictly and consistently.

8. No fallback options if the claim fails

Unlike the United States, Benelux does not offer a Supplemental Register or similar fallback.

If acquired distinctiveness is not proven:

• The descriptive word mark is refused
• The application cannot proceed in reduced form
• The refusal applies to the entire Benelux region

This makes reliance on acquired distinctiveness a high-risk strategy.

9. Practical alternatives to relying on acquired distinctiveness

Because the evidentiary burden is so high, applicants often choose alternative strategies, such as:

• Filing a distinctive logo or figurative mark
• Adopting a more distinctive word mark from the outset
• Using the descriptive wording as marketing language rather than as a trademark

These approaches are often faster, more predictable, and less costly.

10. Key takeaway

Proving acquired distinctiveness in Benelux is possible in theory but difficult in practice.

The decisive rule is clear:

• Consumer recognition must be proven in Belgium, the Netherlands, and Luxembourg
• Evidence limited to a single country is not enough
• There is no fallback register if the claim fails

For most applicants, relying on acquired distinctiveness in Benelux is a high-bar, high-risk strategy that should be carefully evaluated before filing.
