International Trademark Search: How to Check Your Brand Name for EU and US Markets?

Новини

Entering the international market is a major and ambitious step for any Ukrainian business. You are ready to adapt your product, set up logistics, and invest in marketing for European or American audiences. But is your main asset—your brand name—ready for this?

A name that is unique and protected in Ukraine may have long been occupied by a well-known company in Germany or a small startup in California. Ignoring this fact is the shortest path to financial losses, customs issues, and lawsuits. In this article, we, the BrandR team, will explain how to conduct “legal reconnaissance”: where and how to check your trademark before entering EU and US markets, and why this step is the most important investment in your international expansion.

Section 1: Why is Ukrainian registration not enough?

Many Ukrainian entrepreneurs, having successfully registered their trademark in Ukraine, mistakenly believe they have obtained some form of “international” protection or at least an advantage when entering foreign markets. This is a dangerous illusion. At the heart of all intellectual property law lies the fundamental principle of territoriality. Understanding this principle is the first and most important step in planning any international expansion.

Subsection 1.1: Territorial nature of TM rights

The principle of territoriality means that trademark rights granted by the government authority of one country are valid exclusively within the geographical borders of that country.

  • A certificate issued by UANIPIO (Ukrainian National Office for Intellectual Property and Innovations) grants you the monopoly right to use your TM only within the territory of Ukraine.
  • A certificate issued by the USPTO (United States Patent and Trademark Office) is valid only within the territory of the USA.
  • A certificate issued by the EUIPO (European Union Intellectual Property Office) is valid in all 27 EU member states, but does not apply, for example, in Switzerland, the UK, or the USA.

There is no single “global” trademark certificate. Your Ukrainian document has no legal force in Poland, Germany, or any other country. For every new territory you plan to enter, you must go through the verification and registration procedure again, in accordance with local legislation.

Subsection 1.2: Risks of entering a new market “blindly”

What happens if you ignore this principle and start selling goods or promoting services abroad without prior verification? You expose your business to a series of serious risks that can negate all your efforts. While you might make one of the «Top 5 mistakes in self-registration of a TM» when working in the domestic market and lose “only” the Ukrainian fees, on the international stage, financial and reputational losses grow exponentially. The main risks include:

  1. Customs issues: this is the first line of defense for rights holders. If the name on your product infringes on the rights of a local company, your shipment can be detained or even confiscated at the border at the request of the rights holder. This will lead not only to direct financial losses but also to missed delivery deadlines and loss of trust from partners.
  2. Immediate lawsuits: unlike Ukraine, where judicial practice can be slow, in EU countries and the USA, intellectual property rights are protected very strictly and quickly. A rights holder can go to court and obtain a preliminary injunction against any of your activities (sales, advertising, participation in exhibitions) within just a few days of your market entry.
  3. Loss of investment: the most significant blow to a business. Imagine you have invested tens of thousands of euros in:
    • Website translation and localization.
    • Launching advertising campaigns on Google and social media.
    • Adapting packaging and printing labels.
    • Warehouse rental and hiring staff.

If it turns out that you do not have the right to use your name, all these investments will be lost. You will have to conduct an urgent and expensive rebranding for that specific market.

Thus, the principle of territoriality is not a legal formality, but a harsh reality of international business. It means that your Ukrainian success and legal status do not give you any advantages or immunity abroad. Before entering each new market, you must treat your brand as if you are launching it from scratch and start with the most important step—a thorough international trademark search.

Section 2: Key databases for verification in the EU and USA

Once you realize the necessity of an international search, a logical question arises: where exactly should you look for information to assess your chances? Fortunately, there are powerful and publicly available online databases that allow you to conduct a basic self-search. This will help you filter out the most obvious conflicts and better prepare for a consultation with a specialist. Let’s look at the key resources for the European Union and US markets, as well as global tools.

Subsection 2.1: Verification in the European Union: EUIPO database

If your main goal is the European Union market, your primary tool for verification is the official EUIPO (European Union Intellectual Property Office) database. This office is responsible for registering EU trademarks (EUTM), which have one huge advantage—they are valid simultaneously in all 27 EU member states.

  • What it contains: this database includes all EU trademarks (EUTM) that have already been registered, as well as those pending registration. This allows you to see not only existing rights but also potential conflicts that may arise in the future.
  • How to search: the official EUIPO website has a powerful search tool called eSearch plus. For an initial check, it is enough to select the “Trade marks” section and enter your name in the search field. The system allows you to filter results by status (registered, applied, refused), Nice classification classes, and other parameters. It is recommended to search not only for exact matches but also for key parts of your name, as well as using different spellings.
  • Important nuance: two-tier protection system. TM protection in the EU is complex. In addition to pan-European TMs (EUTM), there are also national trademarks of each individual member state (e.g., Germany, France, Italy), which are registered with national offices. These rights coexist. This means there might not be a single European TM “Astra,” but there could be a national TM “Astra” registered with the German Patent and Trade Mark Office (DPMA) that will prevent you from operating specifically in the German market. Therefore, for a complete picture, in addition to the EUIPO database, it is necessary to check the national registers of the EU countries key to you, which significantly complicates self-searching.

Subsection 2.2: Verification in the USA: USPTO database

To enter the extremely competitive but also very attractive market of the United States, you need to carefully check the USPTO (United States Patent and Trademark Office) database.

  • What it contains: the official USPTO database contains information on all federal trademarks that are registered, filed for registration, or have expired in the USA.
  • How to search: the USPTO website has a search system called TESS (Trademark Electronic Search System). It is quite complex for an untrained user. For beginners, it is best to use the “Basic Word Mark Search (New User)” option. Here you can enter your name and get a list of exact or similar matches. For deeper analysis, professionals use the “Free Form Search (Advanced Search)”, which allows you to build complex search queries using logical operators.
  • Important nuance: first-use principle. The US legal system has a key feature. In addition to the “first to file” principle, the doctrine of “first to use” in commerce also applies here. This means that even if a company has not registered its TM, but can prove (e.g., through invoices, advertising materials, reviews) that it has used this name in the market for a long time before you, it may have priority rights in its region (state). This significantly complicates the analysis, as you need to check not only the official register but also the general brand presence in the US market (via Google, business directories, etc.) to avoid conflicts.

Subsection 2.3: Global verification: WIPO Global Brand Database

This is the most powerful free tool for conducting a broad international search, which is ideal for initial screening. The Global Brand Database from WIPO (World Intellectual Property Organization) is a mega-database that aggregates data from dozens of sources in one place:

  • National registers of many countries around the world (including Ukraine, USA, Canada, UK, etc.).
  • Regional databases, such as EUIPO (EU) and ARIPO (Africa).
  • The database of international registrations under the Madrid System—these are applications filed for several countries at once through a single procedure.

Why is this tool useful? It allows you to check your name across dozens of jurisdictions with a single query. You can filter results by country, TM status, and Nice classes. It is an ideal tool to quickly assess how “occupied” your name is on a global level and identify the most obvious conflicts in different parts of the world. However, keep in mind that this is an aggregator, and sometimes data in it may be updated with a certain delay. Therefore, to get the most accurate and detailed information for a specific country, it is always better to additionally consult primary sources—national databases and EUIPO/USPTO databases.

Thus, for basic self-verification, there are powerful international tools such as the EUIPO, USPTO, and WIPO databases. They allow you to identify the most obvious conflicts and get a general idea of the situation. However, the volume of information in them is huge, interfaces are often complex for a non-specialist, and most importantly, the correct legal assessment of found similarities requires deep knowledge of international law and the practices of foreign offices.

Section 3: Features of international search: what to consider?

Conducting a search in international databases is only half the battle. Unlike checking in Ukraine, international TM search requires taking into account a much larger number of nuances that can fundamentally affect the result and success of your expansion. This is not just a check against more registers, but a comprehensive linguistic and legal analysis that takes into account the specifics of each individual market. Ignoring these features can lead to unexpected problems even if no direct matches are found in the databases.

Subsection 3.1: Language barrier and semantic similarity

This is one of the most important and least obvious features for an entrepreneur. Your name, which is unique and pleasant-sounding in Ukraine, may have a completely different meaning or evoke unwanted associations in another country.

  • Direct translation: it is necessary to check not only the transliteration of your name but also its translation into the language of the target market. If your Ukrainian TM “Syla” (Strength) is registered for energy drinks, you will not be able to enter the Spanish market with the name “Fuerza” or the German market with the name “Kraft” if similar registered marks already exist there.
  • Negative connotations and slang: this is an even more subtle problem. A word that has no subtext in the Ukrainian language may turn out to be a swear word, funny, or have a vulgar meaning in the slang of another language. A classic example is the attempt by the “Chevrolet” company to launch the “Nova” car in the Latin American market (which sounds like “no va” in Spanish—”doesn’t go”). Sales were a failure until they rebranded. Such linguistic verification is a mandatory part of international analysis.
  • Phonetic similarity to local words: your name might accidentally sound the same as a popular local word, which can create confusion or, conversely, help (if the association is positive), but this needs to be known in advance.

Subsection 3.2: Different legal systems and practices

Although the foundations of intellectual property law are similar in many countries, the devil, as always, is in the details. Approaches to assessing designations, procedural requirements, and judicial practice can differ significantly. This complicates self-analysis, just as confusion in basic concepts often leads entrepreneurs to not understand exactly what they need to protect. We wrote in detail about the differences between these key elements in the article «Trademark, brand, logo: what is the difference?». In international registration, these differences become even more critical.

  • Criteria for descriptiveness: a word that is considered fanciful in Ukraine may be deemed descriptive in an English-speaking country if it is such in the English language. For example, the name “Clever” for educational services is highly likely to be refused in the USA or the UK as descriptive, whereas in Ukraine it might have a chance of registration.
  • Practice of assessing similarity: the level of “strictness” of experts in different offices varies. What EUIPO might recognize as dissimilar designations, a more conservative office in another country might consider similar to the point of confusion. This requires knowledge not only of laws but also of the current practice of a specific office.
  • Specifics of US legislation: as we have already mentioned, in the USA, in addition to registration, the fact of first use in commerce plays a huge role. This means that your rights can be challenged not only by the owner of a registered TM but also by a company that can prove it used a similar name in the market before you, even without having a registration.

Thus, international search is not just expanding the geography of the check. It is a comprehensive linguistic, cultural, and legal analysis that requires taking into account the specifics of each individual market. Underestimating these features can lead to failure even if your name looks “clean” at first glance.

Section 4: Why is a specialist necessary for international search?

After familiarizing yourself with the main databases and the features of international analysis, it becomes obvious that self-searching on a global level is an extremely complex, time-consuming, and risky task. Trying to save money at this stage can lead to strategic miscalculations that will negate all efforts to enter new markets. Engaging a professional lawyer or patent attorney to conduct an international search is not a luxury, but a rational business necessity that ensures accuracy, efficiency, and reliability.

Subsection 4.1: Saving your most valuable resource—time

Imagine you need to conduct a thorough search in three key EU countries, the pan-European database, and the US database. This means you will have to:

  • Understand the interface and search logic of five different, often non-intuitive, systems.
  • Conduct a search in each database using dozens of variations of spelling, transliteration, and translation of your name.
  • Analyze hundreds or even thousands of found results, trying to distinguish relevant from irrelevant ones.
  • Try to understand the legal status of each found TM.

Performing this task independently can take an untrained person weeks of painstaking work, and even then, there will be no certainty about the completeness and correctness of the results. A specialist who has experience and specialized software performs this work much faster and more efficiently, freeing up your time for solving strategic business tasks.

Subsection 4.2: Professional report and objective risk assessment

The main difference of a professional approach lies not in the number of results found, but in the quality of their analysis. Instead of a set of incomprehensible links and screenshots, you receive a structured, understandable written report, which is the basis for making an informed decision.
Such a report usually includes:

  • List of identified conflicting TMs for each country, with detailed information about their owners, classes, and status.
  • Analysis of the degree of similarity and the probability that the examination of the relevant office will recognize your designations as similar.
  • General conclusion about the level of risk for each jurisdiction (low, medium, high).
  • Clear recommendations: For example, “Entering the German market is not recommended due to the high risk of conflict, the Polish market is possible provided a consent letter is obtained, the French market has minimal risks.”

This gives you not just information, but its expert interpretation, which allows you to make the right business decision.

Subsection 4.3: Developing an international registration strategy

Search is only the first step. The next is developing an optimal strategy for protecting your brand abroad. And here, the help of a specialist is indispensable. Based on the search results and your business goals, BrandR specialists will help you choose the best path:

  • National applications: file separate applications in each priority country. This is advisable if you are only interested in 1-2 countries.
  • Regional application: file a single application for a European Union trademark (EUTM) to obtain protection in 27 countries at once.
  • International procedure: use the Madrid System, which allows you to extend protection to several countries at once (e.g., EU, USA, UK) based on your Ukrainian application or registration through a single procedure.

Choosing the right strategy allows you to significantly optimize costs and time for obtaining international protection.

Thus, turning to professionals to conduct an international TM search is not an additional expense, but an investment in accuracy, efficiency, and strategic planning. It allows you to get an objective picture of risks, avoid fatal mistakes at the start of international expansion, and develop the right legal protection strategy that will meet your global ambitions.

Conclusion

Entering the international arena is an exciting but extremely responsible step for any business. And it should start not with logistics or marketing, but with legal “reconnaissance”—a thorough international check of your trademark.

As we have found out, a Ukrainian certificate is not valid abroad, and self-searching in international databases is complex and risky. Underestimating the linguistic and legal features of each market can lead to loss of investment, lawsuits, and the complete failure of your expansion. A professional international search is not a luxury, but a necessary foundation on which the safety and success of your business on a global scale depend.
