Why a Trademark Search is Critical Before Filing
A similarity search is an analysis of the IP office database for identical or similar marks within your Nice classification classes, acting as a reliable insurance policy for your budget against refusals and lawsuits. Professional trademark registration always begins with such an audit to identify risks before paying government fees.
Algorithm for searching similar marks
An effective search methodology is based on the sequential analysis of state registers and the proper filtering of business categories. We will examine in detail the technical aspects of working with databases and the principles of selecting homogeneous goods according to your business model.
Filtering by Nice Classification
Filtering results by selected Nice classes is not just a way to shorten the list of found marks, but a strategic tool for risk assessment. When conducting a trademark search by Nice classes, we focus on those market segments where your brand will actually operate. Searching in all 45 classes simultaneously often creates “white noise”: you see hundreds of similar names in metallurgy or pharmaceuticals that in no way interfere with your clothing store or IT service. The lawyer’s main task here is to filter out irrelevant matches and focus on conflict zones.
The algorithm for a preliminary search by category looks like this:
- Defining the core: identifying the primary class (for example, class 25 for footwear manufacturing).
- Analysis of related niches: mandatory checking of classes where services may overlap (for example, class 35 for the retail sale of that same footwear).
- Assessing name “availability”: if an identical mark is found in your class, we analyze its registration date and status (whether the certificate’s validity period has expired).
If matches are found in the selected category, a specialist will help adjust the application strategy. Professional trademark registration involves choosing wording for the list of goods and services that minimizes the risk of refusal and leaves room for business scaling without infringing on the rights of third parties.

Criteria for the similarity of goods and services
Understanding the principles of homogeneity allows you to precisely define the scope of your brand’s protection. In the following subsections, we will examine the legal logic of comparing goods and the specifics of formulating a list for the successful completion of an examination.
Homogeneity Determination Table
Within the analysis of criteria for the similarity of goods and services, the key concept is homogeneity. This is a legal term meaning that a consumer may perceive goods from different manufacturers as originating from the same source due to their functional similarity or shared distribution channels. Even if the names are not identical, but merely similar, an overlap in the area of use can become a fatal obstacle to registration.
To independently assess the risks of overlap with already registered marks, you should refer to the following comparison table:
| Evaluation Criterion | High-risk indicators (homogeneity) | Low-risk indicators |
|---|---|---|
| Purpose | Goods satisfy the same need (e.g., coffee and tea). | Goods have completely different functions (e.g., footwear and computers). |
| Consumer | Shared target audience (e.g., professional builders). | Different segments (e.g., children’s toys vs. industrial equipment). |
| Sales Channels | Sold on the same shelves or in specialized departments. | Sold through fundamentally different networks or platforms. |
It is worth remembering that the conclusion regarding homogeneity is always individual. For example, under certain conditions, software (Class 9) and software development services (Class 42) may be considered homogeneous, but this depends on the specifics of the particular application. A thorough trademark search before paying fees will help minimize the risk of refusal. Now, let’s move on to how to technically adapt standard category names to the actual needs of your business.
Legal nuances of formulating a list
Formulating a list of goods and services is a strategic stage where the precision of wording directly impacts the successful registration of a trademark. To avoid conflicts, use a preliminary adaptation algorithm:
- Activity analysis: Identify 5–7 critical items for which you are actively trading or providing services.
- Narrowing categories: Replace general terms (e.g., “software”) with specific, targeted wording (e.g., “downloadable mobile applications for financial monitoring”).
- Strategic buffer: Add 2–3 related items that have potential for brand development.
| Similarity criterion | Risk in formulation | Minimization method |
|---|---|---|
| Homogeneity | Goods from different classes are recognized as similar (e.g., classes 29 and 32) | Clear differentiation of purpose and distribution channels in the description |
| Phonetics/Visuals | High probability of overlap with existing marks | Refining the product specification to exit the competitor’s “legal corridor” |
If a similar brand is found in the chosen class, assess whether your goods belong to the “homogeneous” category. If so, try to further detail the list, excluding items that overlap with the competitor. Remember that in the official Nice Classification, you can always find clarifications that will help distinguish your activities from those of existing rights holders.
Action plan for detecting similarities
Discovering a similar brand during a search is not a verdict, but merely a signal to adjust your strategy. Let’s look at the options for action that allow you to legally bypass obstacles and successfully complete the registration process for your own trademark.
Protection Strategy Checklist
Preliminary analysis allows for the identification of potential conflicts before filing an application, which is critical because government trademark registration fees are non-refundable in the event of a refusal. Professional verification involves an in-depth search of IP Office databases and an analysis of legal risks, which helps avoid refusal during the substantive examination.
The verification algorithm is based on assessing phonetic, visual, and semantic similarity, as well as the principle of “homogeneity.” Goods are considered homogeneous if a consumer might mistakenly believe they are produced by the same manufacturer due to shared purpose or distribution channels.
| Criterion | What we analyze | Risk example |
|---|---|---|
| Visual | Style, colors, font | Similarity in the design of a graphic element |
| Phonetic | Sound of the name | Similarity in pronunciation leading to confusion |
| Semantic | Meaning, translation | Use of words with identical meanings |
How to minimize risks after a search
Successful brand registration begins not with the submission of documents, but with an in-depth risk analysis, where a trademark search across Nice Classification classes serves as the primary safeguard against future litigation. To avoid clarification requests from the IP Office (UANIPIO) examiners, it is important not to simply copy standard category headings, but to adapt the list to actual goods—for example, narrowing the broad concept of “clothing” to specific niches if similar trademarks are already present in the chosen class. If you operate in the fashion industry, I recommend studying separately which Nice Classification classes to choose for clothing to ensure the brand has the maximum level of protection without unnecessary expenses.
When conflicting marks are identified during the search phase, the most effective strategy is differentiation through detailed wording of the list or obtaining a letter of consent from the owner of the previously registered mark. Understanding how to properly select Nice Classification classes allows you not only to save on government fees but also to create a legal foundation for scaling your business without the fear of being refused due to the “homogeneity” of goods. A well-prepared application is your peace of mind and an asset that will work for the company’s reputation for decades.
Frequently Asked Questions
Is it possible to register a trademark if a similar one already exists in the registry but for a different type of activity?
Yes, this is entirely possible thanks to the principle of specialty, upon which the International Classification of Goods and Services (Nice Classification) is based. Legislation allows for the coexistence of identical or similar trademarks if they are used for goods or services that do not overlap and do not mislead the consumer.
However, it is important to consider the following:
- No likelihood of confusion: The consumer should not think that your goods and the goods of another company originate from the same source.
- Brand fame: If a “well-known” trademark exists (e.g., Apple or Coca-Cola), its protection may extend even to classes where it is not registered.
- Related niches: If you are registering in a related field, the examination may deem your goods to be homogeneous, which will lead to a refusal.
What is a “Letter of Consent” and how does it help with registration?
This is an official document in which the owner of a previously registered similar trademark grants their consent for the registration of your designation. It is one of the tools that allows you to overcome a preliminary refusal based on the results of an examination.
Key aspects of using a letter of consent:
- It is not a guarantee of registration, but it significantly increases the chances, as it indicates that the owner of the existing TM does not see this as an infringement of their rights.
- The document must clearly define the conditions of coexistence (for example, restrictions regarding territory or specific subcategories of goods).
- The IP office expert still conducts their own verification: if there is a risk of misleading the public (for example, in the field of food safety or pharmaceuticals), even the presence of a letter of consent may not save the situation.
How does the use of a domain name affect trademark protection?
It is important to understand that registering a domain name does not grant you trademark rights. You may use a domain for years, but without a registered trademark, you are not protected against someone else filing for the same name and subsequently demanding the transfer of your domain through the courts.
Trademark registration provides the following advantages:
- You gain the exclusive right to use the designation in commercial activities, which serves as a stronger argument when defending a domain (for example, in UDRP proceedings).
- It serves as the “foundation” for intellectual property: you can sell the trademark, license it for use, or contribute it as an intangible asset to the company’s authorized capital.
What are the risks of changing a logo or name during registration?
Changing designation elements during the registration process is a complex procedure that is effectively equivalent to filing a new application. According to the legislation of Ukraine:
- You can only make minor corrections that do not change the essence of the trademark (for example, correcting a typo).
- If you change the logo graphics or add new words, you will have to file a new application and pay all state fees again.
Tip: Always conduct an in-depth preliminary search of the exact final version you plan to submit to avoid the need for changes during the examination stage.
Why is it important to detail the list of Nice Classification goods rather than just copying class names?
Copying the entire list of goods and services for a specific class “just in case” is a strategic mistake that increases the chances of encountering existing trademarks. Every additional item in an application is a potential conflict.
The correct strategy is to narrow down the list:
- Focus on reality: Specify only those items that you actually produce or provide.
- Specification: Instead of the broad term “Clothing” (Class 25), it is better to specify “yoga clothing made from eco-friendly materials.” This helps to differentiate your brand from those that already occupy the general clothing niche.
- Risk reduction: The more narrowly the list is formulated, the less likely it is that the examination will find a “similar mark” in the database.
