How the OEPM Examines Trade Marks: The “No Ex Officio” Rule and the 2-Month Opposition Window

Spain’s trade mark examination system operates on a principle that surprises many applicants, particularly those coming from Latin American or U.S. systems where the registry actively blocks conflicting marks: the Spanish Patent and Trade Mark Office (Oficina Española de Patentes y Marcas, OEPM) does not refuse applications ex officio on relative grounds. This means that even if a new application is identical or confusingly similar to an existing registration, the OEPM will not block it unless the owner of the earlier mark takes action. Understanding this procedural reality — and the strict 2-month opposition window that accompanies it — is essential for anyone seeking to register or defend trade marks in Spain.

The Legal Framework: Ley 17/2001 (The Trade Mark Act)

Spain’s trade mark system is governed by Ley 17/2001 de Marcas (the Trade Mark Act), as amended by Royal Decree-Law 23/2018, which transposed EU Directive 2015/2436 into Spanish law. The examination procedure is designed to mirror the system used by the European Union Intellectual Property Office (EUIPO) for EU trade marks, ensuring that national Spanish marks are not subject to a more rigorous examination than EU-wide marks that produce identical effects in Spain.

The rationale, as stated in the Trade Mark Act’s preamble, is explicit: relative prohibitions protect private rights, and the defence of those rights should be left in the hands of the interested parties themselves, not imposed by the Administration. The interested parties enjoy full guarantees through the opposition procedure and through invalidation actions.

What the OEPM Does Examine: Absolute Grounds

The OEPM does examine applications ex officio for compliance with the absolute grounds for refusal set out in Article 5 of the Trade Mark Act. These include:

• Lack of distinctiveness: Signs that are devoid of distinctive character.
• Descriptiveness: Signs consisting exclusively of elements that describe the kind, quality, quantity, intended purpose, value, geographical origin, or other characteristics of the goods or services.
• Generic terms: Signs that have become customary in the current language or established practices of the trade.
• Deceptive marks: Signs that are liable to mislead the public as to the nature, quality, or geographical origin of the goods or services.
• Marks contrary to public order or morality.
• Protected emblems and insignia: State flags, official symbols, and similar protected designations.
• Marks incorporating another person’s name or portrait without consent.

If the OEPM identifies any absolute ground for refusal, it issues a provisional refusal (suspensión), and the applicant has one month to respond with arguments or to withdraw, limit, amend, or split the application.

What the OEPM Does Not Examine: Relative Grounds

This is the critical distinction. The OEPM does not refuse applications ex officio based on relative grounds — that is, based on the existence of prior trade mark rights. No matter how identical the new application is to an existing registration for the same goods, the OEPM will not block the application on its own initiative.

However, the OEPM does provide a courtesy notification. Upon publishing the application, the OEPM conducts an electronic search of the register and notifies the owners of potentially incompatible earlier rights that a new application has been filed. This notification is purely informational — it alerts the prior owner to the existence of the new application so they can decide whether to file an opposition. The OEPM will not take any action on their behalf.

This means that if the prior mark owner does nothing — ignores the notification, misses the deadline, or simply chooses not to oppose — the new application will proceed to registration, regardless of the conflict.

The 2-Month Opposition Window

Once the OEPM publishes the trade mark application in the Boletín Oficial de la Propiedad Industrial (BOPI) (the Industrial Property Official Gazette), a strict 2-month opposition period begins. During this window:

• Any party that believes its rights may be damaged can file an opposition. This includes holders of prior trade mark registrations, prior applications, well-known unregistered marks, copyrights, trade names, company names, or domain names.
• Oppositions may be based on relative grounds (prior conflicting rights under Articles 6–10 of the Trade Mark Act) or absolute grounds (Article 5).
• Public authorities, consumer associations, and national organisations may also submit written observations regarding absolute grounds, although they do not become parties to the proceedings.

Once an opposition is filed, the OEPM notifies the applicant and grants a one-month period to respond. The applicant has three main options:

• Respond with arguments: File a statement of grounds explaining why the opposition should be dismissed.
• Request proof of use: If the opposing mark has been registered for more than five years, the applicant can require the opponent to prove genuine use of their mark during the five years preceding the application or priority date. If the opponent fails to provide sufficient evidence within one month, the opposition is dismissed.
• Negotiate: Approach the opponent to explore coexistence, consent, or narrowing of goods and services.

After the applicant’s response (or expiry of the response period), the OEPM issues its decision granting or refusing registration. The decision is published in the BOPI.

The Post-Registration Safety Nets

If a prior mark owner misses the 2-month opposition window, they are not without remedy — but the available options are more costly and complex:

• Invalidation proceedings before the OEPM: Since January 14, 2023, the OEPM has direct competence to hear administrative proceedings for the invalidation of registered trade marks. A prior mark owner can request that a conflicting registration be declared invalid based on relative grounds. This represents a major procedural shift — previously, invalidation actions could only be brought before the civil courts, which was significantly more expensive and time-consuming.
• Court proceedings: Civil courts retain jurisdiction over invalidation claims raised as counterclaims in infringement proceedings.

Why This Matters: The Practical Consequences

The no-ex-officio rule creates a system where the burden of policing the register falls entirely on existing trade mark owners. The OEPM will not protect your rights for you. This has several practical consequences:

• Monitoring is essential: If you own trade marks in Spain, you must actively monitor the BOPI for potentially conflicting applications. The 2-month opposition window is the most cost-effective point to challenge a conflict.
• The courtesy notification is not guaranteed: While the OEPM conducts an electronic search and notifies potentially affected owners, this is an automated process based on the registry data. If your contact details are outdated, or if the search algorithm does not capture the similarity, you may not receive a notification at all.
• Speed is critical: Two months is a relatively short opposition window compared to some jurisdictions. Once the window closes, the only options are invalidation or court proceedings — both more expensive and slower.
• Professional watch services: Most serious brand owners in Spain engage professional watch services that monitor the BOPI systematically and flag potentially conflicting applications in time to assess and act.

How This Differs from Other Systems

Applicants accustomed to systems like Chile (INAPI), Mexico (IMPI), or the United States (USPTO), where the registry actively examines and refuses applications on relative grounds, must adjust their expectations when filing or defending marks in Spain. In those systems, the examiner functions as a first line of defence for prior mark owners. In Spain, there is no first line of defence unless you create one yourself.

This approach is aligned with the EU trade mark system at the EUIPO, where EU trade marks are also not examined ex officio on relative grounds. The OEPM’s adoption of this model was a deliberate policy choice to ensure parity between national and EU-wide marks.

Strategic Recommendations

• Engage a professional watch service: This is non-negotiable for any serious brand owner in Spain. The no-ex-officio rule means the registry will not protect you — only you can protect yourself.
• Keep contact details updated at the OEPM: Ensure that your address for correspondence and representative details are current, so you receive the courtesy notification if a conflicting application is detected.
• Act within the 2-month window: Oppositions are the most efficient and cost-effective tool for blocking conflicting applications. Missing the deadline dramatically increases the cost and complexity of challenging a registered mark.
• Use the proof of use request strategically: If the opposing mark has been registered for more than five years, requiring proof of use can be an effective way to defeat or narrow the opposition.
• Consider the OEPM invalidation route: Since January 2023, administrative invalidation proceedings before the OEPM provide a faster and cheaper alternative to court action for marks that have already been registered.

Common Mistakes

• Assuming the OEPM will block conflicting marks: It will not. The no-ex-officio rule means your prior registration provides a right to oppose, not an automatic block.
• Relying solely on the OEPM courtesy notification: This is informational and not guaranteed. A professional watch service is the reliable safeguard.
• Missing the 2-month opposition deadline: The window is strict and non-extendable. Late action means resorting to invalidation or court proceedings.
• Ignoring the Spanish register because you hold an EUTM: EU trade marks and Spanish national marks coexist. A conflicting Spanish application must be opposed separately from any action regarding EU trade marks.
• Failing to request proof of use: When the opponent’s mark has been registered for over five years, the proof of use requirement is a powerful defence that applicants frequently overlook.

Key Takeaway

Spain’s no-ex-officio system for relative grounds places the responsibility for defending prior rights squarely on the shoulders of trade mark owners. The OEPM will examine absolute grounds and provide informational notifications, but it will not refuse an application simply because a conflicting mark exists on the register. The 2-month opposition window is the critical juncture — miss it, and the cost of challenging a registered mark rises significantly. For brand owners in Spain, proactive monitoring, timely opposition, and current registry details are not just good practice — they are the foundation of trade mark protection.
