Procedural Risk in Greece Under Law 4679/2020: Office Actions, Opposition, Non-Use, Madrid

Trademark registrability in Greece is not determined solely by whether a mark is distinctive and clear of prior rights. Procedural risk plays a separate and often decisive role. An otherwise sound mark can fail because a formal office action is mishandled, because an opposition is not strategically defended, because an earlier right survives or collapses on proof-of-use, or because a Madrid designation triggers a provisional refusal on local formalities. For businesses and legal teams, understanding these procedural pressure points under Law No. 4679/2020 is critical to reducing both filing failure and later portfolio vulnerability.

The Legal Framework: Law No. 4679/2020

• Article 20: Governs initial examination stages.
• Article 21: Covers formal deficiencies and the opportunity to correct them.
• Article 22(1)(στ): Requires transliteration of non-Greek or non-Latin script where applicable.
• Article 24(3): Allows the examiner to raise absolute-ground objections and invite response or limitation within 30 days.
• Article 25(1): Sets the three-month opposition period after publication.
• Article 28: Establishes proof-of-use requirements for earlier marks in opposition and related proceedings.
• Article 29: Supports appeal routes from examiner decisions to the Administrative Trademark Committee as described in the guide.
• Article 30: Establishes the Administrative Trademark Committee.
• Article 32: Provides for judicial review before the administrative courts.
• Article 50: Provides for revocation of a registered trademark for non-use after five consecutive years.
• Article 52: Provides for invalidity actions based on absolute or relative grounds.

Procedural Risk Factors in Greek Trademark Practice

Greek trademark risk often arises in four recurring forms. First, office actions can terminate or weaken an application if formal or substantive objections are not handled within strict deadlines. Second, oppositions can block registration even where the office itself did not identify a relative-ground problem during examination. Third, non-use rules can deprive an earlier right holder of opposition leverage or can later expose a registration to revocation. Fourth, Madrid designations can fail on Greece-specific issues such as transliteration or substantive absolute-ground objections.

The standard applied by the Greek authorities is procedurally formal. Deadlines matter. Documentary completeness matters. Goods and services wording matters. And because the opposition system is active and proof-of-use has real force, applicants should think about procedural readiness long before publication.

What the Directorate of Trademarks and OBI Consider Procedurally Important

Office actions and examiner objections

Formal office actions under Article 21 typically concern missing information, unclear representation, defective classification, or missing transliteration. The applicant generally has 30 days to cure the defect. If the defect is not corrected, the application may be rejected or treated as abandoned without advancing to substantive review.

Substantive objections under Article 24(3) usually concern absolute grounds. The same short response culture applies: the applicant is generally given 30 days to respond, limit the goods and services, or present argument and evidence. In practice, the quality of the first response matters. Weak responses can lock the case into an unfavorable path and make appeal more difficult.

The office also expects applicants to comply with local script requirements. For multilingual marks, the Greek system pays attention not only to the mark as displayed but also to how it will be transliterated and understood. This is a recurring source of procedural friction for international filers.

Opposition practice

After acceptance and publication, Article 25 opens a three-month opposition period. Oppositions may be based on absolute or relative grounds. For absolute grounds, broader categories of parties, including associations, may have standing. For relative grounds, standing is limited to owners of earlier rights.

Opposition risk is heightened where:

• The specification is broad: more goods and services increase the number of earlier rights potentially affected.
• The mark is close to a crowded field: even if no exact-match conflict exists, similar earlier marks can emerge.
• The mark contains weak or descriptive elements: these may attract both absolute-ground and relative-ground challenges.
• The applicant lacks a litigation-ready record: poor file management can make it difficult to rebut claims quickly.

Oppositions are heard by the Administrative Trademark Committee. Fees are relatively modest according to the guide, which means the economic barrier to opposition is not high. Applicants should therefore assume that commercially important marks may be challenged.

Proof of use and non-use vulnerability

Article 28 proof-of-use is one of the most significant procedural risk filters in Greece. In opposition, the applicant may require the opponent to prove genuine use of the earlier mark if the mark is old enough. This can be outcome-determinative. An opponent with a dormant registration may lose standing for practical purposes if it cannot produce invoices, advertising, packaging, or other real-use evidence.

Article 50 creates the mirror-image risk for proprietors. Once a mark has been registered for five years, it becomes vulnerable to revocation if it has not been genuinely used for the registered goods or services. Partial revocation is also possible. For portfolio management, this means that registration alone is not a stable endpoint; ongoing use and evidence retention are essential.

Madrid provisional refusals

International registrations designating Greece are examined under the same substantive law. A Madrid designation can receive a provisional refusal for descriptiveness, lack of distinctiveness, deceptive character, conflict with earlier rights, or formal defects. Greece-specific formal issues include transliteration under Article 22(1)(στ). The practical consequence is that WIPO-level filing regularity does not eliminate local Greek requirements.

Madrid refusals should be treated with the same seriousness and timing discipline as national office actions. The response often requires local legal analysis even if local representation is not always formally mandated by the guide.

Key Case Law

No leading Greek cases have been published in the source guide with full citation details specifically on office-action practice, opposition procedure, non-use revocation mechanics, or Madrid provisional refusals under Law No. 4679/2020. Where the guide does not confirm a citation, no leading cases have been published.

The Procedure for Responding to Office Actions, Oppositions, Non-Use Challenges, and Madrid Refusals

1. Formal office action response

Upon receiving a formal deficiency notice under Article 21, correct the defect within the usual 30-day period. Typical cures include rewording goods, supplying a clearer mark representation, or filing the necessary transliteration. Confirm that the correction fully addresses the issue rather than partially responding.

2. Substantive office action response

If the examiner raises an absolute-ground objection under Article 24(3), prepare a response that is both legal and factual. Options include limiting the specification, arguing consumer perception, emphasizing distinctive figurative elements, or presenting Article 4(2) evidence where applicable. File within the 30-day period.

3. Appeal from examiner refusal

If the application is refused, appeal to the Administrative Trademark Committee within the period stated in the guide, generally 60 days from notification. The appeal should identify legal errors, factual errors, and any relevant evidence overlooked or insufficiently weighed.

4. Opposition defense

When an opposition is filed, first classify it: absolute grounds, relative grounds, or both. For relative grounds, examine whether Article 28 proof-of-use can be invoked against the earlier mark. Then prepare a structured defense on standing, similarity of marks, similarity of goods, the strength of the earlier right, and any market distinctions.

5. Non-use cancellation defense

If a mark is attacked under Article 50, assemble genuine-use evidence covering the five-year period and the goods or services actually used. Evidence should show use in commerce in Greece and should be organized by date and product category. If the mark has only been used for part of the register, assess whether partial revocation should be conceded strategically.

6. Madrid provisional refusal response

For a provisional refusal of a Greek designation, review whether the issue is formal, absolute, or relative. Cure local formalities such as transliteration immediately. For substantive issues, prepare a Greece-specific response grounded in Law No. 4679/2020 rather than generic WIPO argument.

7. Judicial review

Where the Administrative Trademark Committee issues an adverse decision, the next step is judicial review before the administrative courts within the applicable statutory deadline indicated in the guide.

Strategic Recommendations

• Recommendation: Calendar every Greek deadline from the date of notification, not from internal circulation. The 30-day and three-month periods are short and operational delay is a common source of avoidable loss.
• Recommendation: Build a use-evidence archive from launch. Sales records, invoices, product photos, advertising, and website captures can become decisive under Article 28 and Article 50.
• Recommendation: For important filings, prepare opposition defenses before publication by mapping likely earlier rights and the use status of potential opponents.
• Recommendation: Review Madrid filings for Greece-specific script and specification issues before designation, especially where non-Latin wording is involved.
• Recommendation: Use specification drafting as a risk-control tool. Narrow, commercially accurate identifications reduce both office objections and opposition surface area.
• Recommendation: In appeals, present a coherent procedural narrative. Greek tribunals respond better to structured statutory argument than to broad assertions of commercial fairness.

Common Mistakes

• Mistake: Treating office actions as administrative housekeeping rather than substantive risk events. In Greece, missed or weak responses can end the application quickly.
• Mistake: Failing to request proof of use against an older earlier mark in opposition. This can leave a strong procedural defense unused.
• Mistake: Assuming that once registered, a mark is secure indefinitely. Article 50 non-use revocation is a real portfolio risk after five years.
• Mistake: Using Madrid as a filing shortcut without checking Greek transliteration and local distinctiveness concerns. Provisional refusals often arise from country-specific details.
• Mistake: Keeping poor evidence of use. Unorganized or undated evidence can fail even where genuine commercial use exists.

Key takeaway: In Greece, procedural discipline is as important as substantive registrability. Applicants and proprietors should manage office actions, opposition timing, proof-of-use strategy, and Madrid local requirements proactively, because procedural missteps can defeat even commercially strong marks.
