Registering a trademark isn't mandatory, but failing to do so can have serious consequences for your business. In Spain and the European Union, the system operates on a key principle: whoever registers first, gets the rights.
In this article I explain, in a clear and up-to-date way, what risks you run if you do not register your trademark, both at the national and European levels.
1. You will not have exclusive rights over your brand
The biggest problem is this:
-Your brand won't really be "yours"“
In Spain, only registration with the Spanish Patent and Trademark Office (OEPM) grants the exclusive right of use.
This means that if you don't register:
-Any other company can use the same name
-You cannot legally prevent its use
-Your brand is left completely unprotected
-Even if you've been using it for years, that doesn't guarantee you exclusive rights.
2. Someone else can register your trademark before you do.
This is one of the most dangerous risks.
If you don't register your trademark:
-A third party can do it first
-And become the legal owner
Then:
-They could force you to stop using your own name
-You would have to change your branding, website, social media, etc.
-You could lose your entire investment
This happens because the system works by registration priority (first to file).
3. You can be sued and have to pay damages
Imagine you use a name without registering it… but a similar trademark already exists.
Consequences:
-Lawsuits for infringement
-Financial compensation
-Withdrawal of products or services
-Even legal sanctions
-The owner of a registered trademark can demand that you stop using it and claim damages.
4. You will not be able to grow or expand safely
If you don't register your trademark:
-You will not be able to expand to other cities or countries
-You might encounter conflicts growing up
-Even if you have used a brand before someone else, you could only have a limited right in your local area, with no possibility of expansion.
5. In the European Union the risk is even greater
In the EU, the trademark system is more competitive and faster.
Current data:
In 2025, approximately 197,000 trademarks were registered in the EU.
This implies:
-A lot of competition
-Higher probability of someone registering your name
-International conflicts
If you don't register at the European level, someone can do it in another country and block you.
6. You can lose your brand overnight
No registration required:
-You have no real legal protection
This means that:
-You can't prevent copies
-You can't control the use of your brand
-You can lose it completely
In fact, you could be forced to abandon your brand immediately if it conflicts with a registered trademark.
7. Your business loses value
An unregistered trademark:
-It can't be sold easily
-It cannot be licensed
-It does not generate real assets
In business terms:
-It is not a legally sound asset
This directly affects:
-investors
-sale of company
-growth
8. You will not be able to defend yourself against copies
If someone copies your brand:
No registration required:
-You can't easily make a claim
-You cannot prevent the use
-You cannot demand compensation
In contrast, a registered trademark allows for the initiation of legal action, including civil or criminal proceedings.
9. Key differences: Spain vs European Union
Spain's European Union aspect
OEPM EUIPO Registration
Protection Only in Spain In the 27 EU countries
Unregistered Risk High Very high
Medium Competition Very High
Conclusion:
Spain → local risk
EU → global risk
10. Are there any unregistered protections?
Yes, but very limited.
You can try to defend:
-previous use
-unfair competition
But:
❌ It's difficult
❌ expensive
❌ does not guarantee success
In general, an unregistered trademark has almost no real legal protection.
CONCLUSION: Is it worth registering a trademark?
Yes, absolutely.
Not registering your trademark implies:
❌ Lose rights
❌ Taking legal risks
❌ limit your growth
❌ jeopardizing your business
While registering it gives you:
✔️ exclusivity
✔️ legal protection
✔️ business value
✔️ Security to grow
