Your Company Name Is Not Your Trademark (And the Difference Could Cost You Your Brand)

You have been trading under the same brand for two years. You registered the company. You own the domain. You are on every platform. And then a letter arrives.

A competitor has registered your brand name as a trademark. In your market. Legitimately.

This is not a hypothetical. It happens. And the reason it happens is that company name registration and trademark registration are two entirely different things — and most founders do not know that until it is too late.

What CRO registration actually gives you

When you register a company name with the CRO (Companies Registration Office) in Ireland, you get a registered company name. That is all.

The CRO is a registry of company names. Its job is to record that a legal entity was incorporated on a particular date. It does not grant any exclusive rights to use that name in the marketplace. It does not stop another company from trading under a similar name. And it does not prevent a third party from registering your brand as a trademark.

The CRO itself notes this. Its own guidance states that applicants should check whether their proposed name conflicts with an existing trademark before proceeding — because the two systems operate independently.

The same is true in the UK. Companies House registers company names. It does not confer trademark rights. A name that passes Companies House clearance may still conflict with an existing trademark. And a name you have registered at Companies House may still be registered as a trademark by someone else.

What a trademark gives you that a company name does not

A trademark is a registered right to use a particular name, logo, or mark in connection with specific goods and services in a specific territory.

Once registered, a trademark gives you:

• The legal right to stop others from using confusingly similar marks in your market

• A basis to pursue infringement if someone copies your brand

• A registered property that can be licensed, valued, or transferred

A CRO registration gives you none of that. Neither does a Companies House registration.

How this plays out in practice

Consider a scenario we see regularly. An Irish founder registers a company in 2022. They choose a distinctive brand name, build a website, grow a customer base, get some LinkedIn traction. In 2024, they receive a letter from a solicitor representing a competitor who registered the same brand name as an Irish trademark — before the founder thought to do it.

The competitor did nothing wrong. They identified an unregistered mark in a growing market and registered it. That is exactly what trademark law is designed to allow.

At that point, the founder's options are limited. They can challenge the registration — but that requires showing the mark was in prior use and that the registration was filed in bad faith, neither of which is straightforward. They can negotiate. Or they can rebrand.

None of those options is cheap. None of them is quick. And all of them could have been avoided for the cost of a trademark clearance search and a filing fee.

The Ireland and UK dimension

If your business operates in both Ireland and the UK — or if you plan to — the trademark position is more complicated than it used to be.

Before January 2021, an EU trademark (EUTM) registered through the EUIPO covered the entire European Union, including the UK. Since Brexit, an EUTM covers EU member states only. The UK is no longer included.

That means Irish founders who filed an EUTM and then expanded to the UK may have no UK trademark protection. A founder with an EUTM, no UK trademark, and a growing UK revenue stream is carrying a brand risk that is easy to fix before it becomes a problem.

What the check costs vs. what rebranding costs

A trademark clearance search — checking whether your intended mark is free to use in Ireland and the UK — takes a few hours of professional time. A basic trademark application in one jurisdiction typically costs a few hundred euro or pounds, excluding professional fees.

Rebranding a company that has been trading for two or more years costs significantly more. New company registration, domain migration, website redesign, updated marketing materials, client communications, updated legal documents. And the intangible cost: rebuilding brand recognition from zero.

An IP audit surfaces trademark status as a standard output item. Not to sell you a trademark filing — but to show you where you stand, what you have, and what gaps exist, so the decisions you make from that point are informed ones.
