Validate your European Patent in Spain

If you want your European patent to be enforceable in Spain, you must do so by validating the European patents in Spain after grant. Spain is not part of the Unitary Patent system, so validation of the European patents in Spain is the only way to obtain patent protection in Spain when there is a granted European patent.

European Patent Protection: How It Works

A European patent granted by the European Patent Office (EPO) can provide protection in up to 39 EPC member states through a single centralised procedure.

However, once granted, a European patent does not automatically take effect in these countries. To obtain protection, you must either:

Validate the EP patent in the countries where you seek protection, and/or
Request a Unitary Patent (for participating states only).

What are Validations of European Patents in Spain?

Validation is the legal process required for a granted European patent to take effect in Spain, which must be conducted within a specific time window.

Why Validation is Mandatory in Spain

Spain is not part of the Unitary Patent system. This means that validating your European patent in Spain is the only way to secure enforceable patent rights in the country.

If your European patent is not validated in Spain, you have no patent protection in this market.

Requirements and Deadlines for Validating a European Patent in Spain

To validate a European patent in Spain, the following must be completed:

Payment of official Spanish Patent and Trademark Office (SPTO) fees. The fees are EUR 278.28 plus EUR 11.19 for each page of the translation over 22, including the pages of the figures regardless of whether they include translated text.
Preparation and submission of a full Spanish translation of the European patent specification, which does not include the abstract.
Appointment of a Spanish-based legal representative or a Spanish Patent and Trademark Attorney.

Deadlines and Extensions of Time

The validation must be completed within 3 months of the publication of the grant of the European patent.

A 2-month term extension can be requested during the initial 3-month window. This extension does not require payment of any official fee, but it must be formally approved by the SPTO before the original deadline expires, thus it must be approved within the 3-month window.

What Happens if the Deadline is Missed?

If validation is not completed in time, the patent will not take effect in Spain, and protection may be lost.

The only means of redress are a re-establishment of rights, which may not be granted by the SPTO.

Why the Spanish Translation is Critical

The scope of protection in Spain is defined by the Spanish translation, not the original text of the European patent as granted. Errors can limit rights, expose the invention, and cannot fully restore protection retroactively.

A mistranslation can:

Narrow or alter the scope of your patent rights.
Expose your invention to exploitation by third parties.
Require costly corrections that do not retroactively restore lost rights.
Allow competitors to continue using your invention if they relied on the incorrect translation.

In short, a poor translation can permanently weaken your patent protection in Spain.

Validation in Spain vs Unitary Patent

Applicants often combine a Unitary Patent with validation in Spain because, if a Unitary Patent is being sought to extend the protection of the European patent in all 18 participating states, a Spanish translation may be filed with the European Patent Office and also be used for validation in Spain.

When applying for a Unitary Patent, it is necessary to submit to the EPO a translation of the granted European patent into the national language of one of the EPC member states, such as Spain. Therefore, if the patent is translated into Spanish for the Unitary Patent or for validation in Spain, the same translation can also be used for the other procedure.

According to the Unitary Patent statistics provided by the EPO, a Spanish translation is filed in more than 30% of Unitary Patent requests. Given that the Spanish market is potentially attractive for most inventions, translating into Spanish is advisable to reduce the costs of a potential validation in Spain.
