Have you found a company or trademark with a name similar to your favourite? First establish exactly what the result represents, who owns it and how it relates to your plans. Then decide whether to search further, hand the information to a professional or choose a different name.
Similarity does not automatically mean a name is prohibited. Equally, saying “we differ by one word” does not resolve it. A check result is the beginning of an assessment, not a final verdict on whether you can use the name.
1. Establish what you have actually found
Separate findings by source:
- A company in the Commercial Register: the registered name of a particular business.
- A trademark or trademark application: a sign with a particular status, territory and list of goods or services.
- A brand online: a name actually used for a product, service or shop.
- A domain: a particular internet address, which may or may not lead to a business operating under the same name.
One entity can appear in several categories. For example, do not treat a domain you find as a complete description of its holder's rights, or replace a trademark search with a search for a company name.
Save the link, date of the check and exact spelling. If a result contains only a shortened name or an unclear summary, open the original record.
2. Gather the details relevant to each type of finding
A similar name in the Commercial Register
Find the full registered name, identification number (IČO) and whether the information is current or historical. For instructions on finding records and reading extracts, see how to search for a company name in the Czech Commercial Register.
For registered business names, Czech law prohibits names that could be confused with another business name or are misleading. This rule appears in Section 424 of the Czech Civil Code. Do not therefore end the check simply because no other company has exactly the same registered spelling.
A similar trademark
Record the registration or application number, owner or applicant, status, relevant dates, territory and specific goods or services. Do not stop at the class number and a preview of the logo. Follow the guide to checking trademarks before choosing a name.
In its guide to checking availability, EUIPO points out possible conflicts between similar signs for similar goods. However, an earlier registration does not in itself mean that another application cannot be filed. You need the full context to reach a specific conclusion.
A brand in use or a registered domain
Find out who operates it, what they offer and which market they serve. If the website is inactive or the details are unclear, record that uncertainty. Do not infer from an apparently abandoned page that all related rights have ceased to exist.
Alongside the legal question, consider practical confusion: will customers find someone else's website, write to a different address or associate your offer with another business? That can be a reason to choose a different name, even if the legal issue ultimately proves manageable.
3. Describe the similarity instead of relying on a feeling
Use these simple questions for your initial notes:
- Which words or parts are identical?
- How are the names pronounced?
- What meaning or association do they suggest?
- What have you added or changed?
- What does each business offer, and in which market is each name used?
Imagine a proposed name, Tichý kompas (“Quiet Compass”), and a result, Kompas studio (“Compass Studio”). These names are fictional illustrations; neither their existence nor their availability has been checked. The example is not intended to decide whether they can be used alongside each other.
A useful note would say: “Both names contain the word Kompas. The other part differs. We need to establish the exact sign, how it is used and the relevant rights.” Neither “we added Tichý, so it is fine” nor “they share one word, so we must discard the name” is a useful conclusion.
If you are uncertain, have the similarity of the whole sign and the significance of its parts assessed. Your own list of questions prepares the information; it does not replace a legal test.
What does not resolve the problem on its own
A different legal form or a generic word. Do not treat adding s.r.o. (the Czech limited liability company designation), studio or service as an automatic answer to possible confusion. What matters is an assessment of the particular name as a whole.
A different domain. Adding a hyphen or changing the extension changes the address. It does not, on its own, resolve a possible conflict over the name you want to use.
A different town. A different registered office is information about the entity, not universal confirmation that you can adopt a similar name.
A different trademark class. Read the list of goods and services and assess the actual relationship between the offers. Even a different sector is not always a complete answer: under specified conditions, the special protection of trademarks with a reputation can extend to dissimilar goods or services. EUR-Lex's summary of the EU trademark explains this principle.
Your own logo. Graphic design does not automatically resolve the issue of a similar word sign. If you intend to rely on it, submit the specific design for assessment.
4. Prepare the information needed for a decision
Before booking a consultation, collect your own proposal and the records you found. You can use this outline:
Our candidate: the exact name and any logo Intended use: company, brand, product or service Offer and markets: specific goods, services and countries Finding: exact sign, entity, record number and links Status and scope: what we know and what we could not establish Question: which similarities or rights need assessment Investment: what has not yet been commissioned and when we want to start
With a brief like this, a notary or lawyer can address a registered business name, and a trademark professional can address a trademark finding, in concrete terms. You do not need to give them your own legal conclusion.
When commissioning a service, check the difference between searching and assessment. For its informational searches, the Czech Industrial Property Office (ÚPV) explicitly states that they do not include an opinion on registrability or the risks of filing an application. A results list alone may therefore leave your main question unanswered.
5. Choose the next step
Is information missing? Complete the search. Do not reach a conclusion from an incomplete preview or an unavailable source.
Do you have a relevant legal concern? Resolve it before filing and making a substantial investment. A note saying “check later” is not a good basis for ordering packaging or launching a campaign.
Is the name difficult to distinguish in practice? Compare it with other candidates. You do not have to keep your favourite at any cost. Another proposal may work better when people recommend or search for your business.
Do you need to negotiate with a rights holder? First obtain advice on the appropriate approach. Do not automatically treat an informal reply saying “we do not mind” as settling every condition of use.
If you are choosing a replacement, return to the brief and develop distinct directions instead of adding letters to the same stem. See how to come up with a company name and choose candidates.
You can generate further ideas and run an initial check on OverNazev.cz. Then assess relevant findings according to their source and scope. The aim is to choose a name whose weaknesses you understand and have addressed before using it.
