When a mark is challenged as descriptive: what it costs to be wrong
A descriptiveness challenge does not just test a word. It tests whether the mark carries any distinctive value at all, and if it fails, the registration falls in full, not only the disputed part. The immediate cost is the loss of the sole right to stop identical use by competitors, backdated to the filing date.
The legal basis
Absolute grounds for refusal or invalidity of a European Union trade mark, including a lack of distinctiveness through pure description, sit within Regulation (EU) 2017/1001 (EUTMR). The regulation governs registration, opposition and invalidity for the unitary EU mark. It does not govern national registrations filed separately in Lithuania or Estonia, which follow their own national acts outside this entry.
What is actually at stake
Losing the argument over descriptiveness is rarely about the word alone. Marketing material, packaging, domain names and licence agreements are usually built around the registered sign. If the registration is cancelled, every downstream document referring to it as a protected mark needs correction, and any enforcement already started against a third party collapses with the right it relied on.
The exposure resembles what happens when a product must change mid-dispute in a different field: When the product is redesigned mid-dispute in practice, a change in the underlying asset forces a change in every contract referring to it, not only the register entry.
What to do, in order
The sequence below assumes the challenge has already been filed and a deadline is running.
- Instruct counsel to pull the full prosecution history and identify which goods or services classes are under challenge.
- Collect evidence of use predating the challenge: invoices, dated packaging, archived marketing material.
- Have counsel assess whether acquired distinctiveness through use can be argued as an alternative to defending the wording itself.
- Decide whether to defend the specification as filed or narrow it voluntarily to protect the strongest part of the registration.
- Where licence or supply agreements reference the mark, review who bears the risk of an invalid asset before the dispute becomes public — the same allocation question surfaces in When a customer demands unlimited liability: who decides and, and it is a negotiated term, not a default assumption.
- File the response within the deadline stated on the notice, not the date it was internally opened.
| Stage | Decides | Typical trigger |
|---|---|---|
| Response to notice | Applicant or registration holder, via counsel | Deadline on the notice |
| First-instance ruling | Opposition or Cancellation Division | Evidence filed by both sides |
| Appeal | Boards of Appeal | Party dissatisfied with first ruling |
| Judicial review | General Court of the European Union | Point of law contested |
Who decides
For a European Union trade mark, the challenge is heard by the European Union Intellectual Property Office. Opposition to a pending application goes to the Opposition Division; invalidity of a mark already on the register goes to the Cancellation Division. Either decision can be appealed to the Boards of Appeal, and a point of law can reach the General Court.
Two scenarios
If the mark was used extensively before filing: build the case on acquired distinctiveness rather than fighting the wording alone. Dated evidence of consistent commercial use often outweighs a purely linguistic argument.
If the challenge comes from a competitor entering the same descriptive space: narrowing the specification may preserve the core of the registration without a full contest, and it is usually faster than litigating the wording to a final ruling.
If the sign also appears in an investment or offering document: disputed status may need disclosure before the document is finalised. The evidentiary question mirrors When the offering document is questioned: who decides and — what matters is what was known and disclosed at the time, not what is discovered afterwards.
What this page does not cover
This page does not set out the substantive test for descriptiveness in a given language or market — that turns on how the relevant public perceives the sign, assessed case by case. It does not quantify the fee charged by the deciding office; fees are published in the office's own tariff and change independently of this material.

Verified: current text of Regulation (EU) 2017/1001 (EUTMR), the primary source for this entry. National implementing measures for Lithuania and Estonia sit outside this registry entry and are not covered here.
Where the question shifts from what the law requires to what can currently be established about a named asset, the report format follows a different logic, illustrated by Asset in Türkiye and the deadline.

FAQ
- What is the first step when a mark is challenged as descriptive?
- Identify the deadline stated on the notice and instruct counsel to pull the full filing history before drafting any response.
- Which deadline is already running?
- The response period set by the office issuing the challenge, counted from the date of the notice itself, not from the date it is opened internally.
- Who decides, and on what evidence?
- The Opposition or Cancellation Division of the European Union Intellectual Property Office decides, based on evidence of use and consumer perception filed by both sides; a point of law can reach the Boards of Appeal and, beyond that, the General Court.
