Mistakes in EU trade mark registration cost more than anywhere else in intellectual property — a single application to EUIPO covers 27 countries at once, which means the price of an error scales across the entire Union immediately. Here are five common miscalculations that most frequently lead to refusal, partial revocation, or protracted litigation.
Skipping a Comprehensive Clearance Search Before Filing
EUIPO examines a sign only against its own database — the Office does not assess relative grounds for refusal on its own initiative. This means an application may pass examination and be registered without issue, and only afterwards encounter an opposition from the proprietor of an earlier national mark or even an unregistered sign with more than local significance — a trade name, a business identifier, a domain name.
The legal basis for such third-party claims is Article 8(4) EUTMR, which recognises rights in unregistered signs used in the course of trade. A comprehensive clearance search must therefore cover not only the EUIPO database but also the national registers of member states via TMview and eSearch plus, as well as domain names and trade names in the relevant jurisdictions.
In our experience, this is the step most commonly skipped by applicants filing without professional support: the assumption is that if EUIPO "let the application through," there are no conflicts. In reality, the absence of an objection at the examination stage guarantees nothing — third-party oppositions are filed after publication, within the fixed three-month window.
Not Using the Trade Mark in the Classes Claimed
The desire to cover as broad a list of Nice classes as possible "just in case" creates a long-term risk. After five years from the date of registration, any third party may file an application for partial revocation for non-use pursuant to Article 58(1)(a) EUTMR — and any classes for which the proprietor cannot demonstrate genuine use will be cancelled.
An important nuance: use is not required in every individual EU member state — what matters legally is genuine use within the Union, assessed in light of the actual market and the goods or services in question. This does not remove the need for discipline: the specification should be limited to the classes and terms the business genuinely plans to use, not those that "might come in handy one day." For more on the mechanism and the practice of Ukrainian and European courts, see our article on Trade Mark Revocation for Non-Use; for guidance on the logic of distributing goods across categories, see our article on the Nice Classification.
Underestimating the Strictness of EUIPO Deadlines
The registration procedure is governed by strict deadlines. Instruments such as continuation of proceedings and reinstatement of rights exist for exceptional cases in unilateral (ex parte) proceedings — but treating them as a safety net is risky: they are the exception, not the standard fallback.
Missing the deadline for responding to an examination objection or for submitting documents is most often fatal, resulting in the loss of the application for a purely formal reason rather than on the merits of the sign. Engaging an authorised representative who manages the deadline calendar and monitors correspondence with EUIPO eliminates this risk almost entirely.
An Incorrectly Formulated Priority Claim
Where an EUTM application is filed within six months of an identical earlier national filing — for example, in Ukraine — the applicant is entitled to claim convention priority and preserve the earlier date of protection. The right to such priority operates on the "triple identity" rule: the same applicant, the same sign, the same list of goods and services.
There is a point here that is frequently overlooked: priority cannot be based on an international registration as the primary basis — only on a national, regional, or already filed EUTM application (EUIPO Guidelines, Priority). An error on this point means losing the advantage of an earlier date — and this is critical if a competitor files a similar sign in the interval between the two applications.
Filing Without an Audit of Absolute Grounds
Unlike relative grounds, absolute grounds for refusal are examined by EUIPO on its own initiative and rigorously. This includes assessing whether the sign is descriptive — whether it merely names the goods or one of their characteristics — or deceptive, for example by indicating a geographical origin that does not correspond to reality.
Where a mark falls foul of these requirements, a refusal will arrive at the examination stage — and this means not only the loss of the official filing fee but also the time spent waiting for a decision. A legal audit of the sign before filing rather than after refusal is one of those rare steps that costs a fraction of the price of dealing with the consequences.

Що з цього випливає для стратегії реєстрації
Реєстрація торговельної марки ЄС — це інвестиція у правовий фундамент бізнесу, і більшість описаних ризиків усувається не додатковими витратами, а плануванням до подання заявки: пошуком колізій, реалістичним переліком класів, контролем дедлайнів і юридичним аудитом позначення. Дешевше на тиждень відкласти подачу заради перевірки, ніж роками захищати вже зареєстровану марку від оскарження чи часткового анулювання.
