Is a Business Name Free? Register, Trademarks, Domains

You have found a name for your business and the .com is free. Good news, but it is only the beginning. A business name can be available as a domain or on Instagram while already being protected by someone else. Here is how to run a serious check, step by step.

This article is for information only and does not constitute legal advice. For full certainty, work with a qualified professional.

Notions Not to Confuse

People often talk about a business "name" as if it were one thing. In reality, several concepts coexist:

• **The company name** (legal or registered name) is the legal name of the entity. It appears in the articles of incorporation and is recorded in the company register.
• **The trade name** is the name under which the business operates and is known to customers. It can differ from the company name.
• **The shop sign** identifies a physical location, such as a storefront.
• **The trademark** is a sign registered with an intellectual property office (such as INPI in France, the EUIPO for the European Union or the USPTO in the United States) for specific goods or services. It grants an exclusive right to use the sign for those goods or services.

A company could therefore be legally named "Smith and Partners Ltd", trade as "Lumen Studio" and own the trademark "Lumen" for its lighting products. Each of these layers needs checking.

Prior Rights

Choosing a name means checking that it does not infringe on earlier rights, often called prior rights. These include:

• an existing registered trademark;
• a company name or trade name used before yours;
• a well-known shop sign in the relevant area;
• a domain name that is actually in use;
• in some cases, copyright or the name of a public body.

It is not only about identical names. The main risk is likelihood of confusion: a name that is visually, phonetically or conceptually similar, used for related activities, can be enough to cause trouble.

The Nice Classes

A trademark is not protected for everything, only for the goods and services listed when it was filed. These are organized according to the Nice Classification, which has 45 classes: 34 for goods and 11 for services.

In practice, a trademark registered for clothing generally does not prevent software from using the same name. However, well-known marks enjoy broader protection. When searching, focus on the classes that match your activity, without forgetting neighboring ones.

Step 1: The Company Register

Start by checking that no company already uses the name in your sector. Most countries offer an online company register search. In France, the national business register can be searched through INPI's online services and the official business directory.

Nomok queries the French company register and shows whether companies with an identical or similar name exist. A match does not automatically mean the name is off-limits: two businesses with the same name can coexist if their activities and locations are very different. But it is a signal worth analyzing.

Step 2: Trademark Databases

This is the most important step. Search:

• **your national trademark office** database (INPI for France, USPTO for the United States, and so on);
• **the EUIPO database** for European Union trademarks;
• **international databases** such as WIPO's if you target other countries.

Do not limit yourself to exact matches. Try spelling variants, plurals and similar-sounding names. Nomok gives you shortcuts to INPI and EUIPO searches for your name: these checks are marked "Check manually", because only a careful reading of the results allows you to draw a conclusion.

Step 3: Domains and Social Media

Once the legal ground is clear, check your name's availability on the domain extensions and social networks that matter to you. A name that is legally free but impossible to get online will force awkward compromises.

Why a Name Free on Social Media Can Still Be a Protected Trademark

This is a common mistake: "the Instagram handle is free, so the name is free." Platforms do not check trademark rights when an account is created. A trademark can have been registered for years without its owner ever opening a TikTok account or buying the .com.

Conversely, a taken account does not necessarily prevent you from using the name as a trademark. Online availability and legal availability are two separate questions.

When to Call a Professional

A personal search quickly rules out names that are clearly unavailable. But assessing likelihood of confusion is subtle. Before investing in a logo, website and printed materials, it is wise to consult a trademark attorney or intellectual property specialist. They can run an in-depth prior rights search and help you file your trademark.

In Summary

1. Distinguish between company name, trade name, shop sign and trademark.
2. Search the company register.
3. Look for identical and similar trademarks in the relevant classes.
4. Check domains and social networks.
5. Have your choice validated by a professional, then file your trademark.
