How Central Attack Can Weaken a Madrid Protocol Filing

Central attack is one of the most misunderstood risks in the Madrid Protocol. A business may believe it has secured trademark protection in 20, 30, or 40 countries through one international registration, only to discover that the whole structure still depends on what happens to the home application or registration during the first five years.

The short version is this: if the basic mark fails during the dependency period, the Madrid international registration can be cancelled or narrowed to the same extent across all designated countries.

That does not mean the Madrid System is unsafe or unsuitable. It remains an efficient route for many brands expanding internationally. The point is more practical: Madrid should be used with a clear view of the basic mark, the first five years, and the countries where losing protection would be commercially unacceptable.

What Does Central Attack Mean Under the Madrid Protocol?

A central attack happens when the basic application or basic registration behind a Madrid international registration ceases to have effect during the five-year dependency period.

Under the Madrid Protocol, an international registration is based on a national or regional trademark application or registration filed with the applicant's Office of origin. That home filing is known as the basic application or basic registration.

For the first five years from the date of the international registration, the international registration remains dependent on that basic mark. If the basic mark is refused, withdrawn, cancelled, revoked, invalidated, renounced, or otherwise loses effect for some or all goods and services, the international registration can be cancelled or limited in the same way.

That is why the term "central attack" is so powerful. One failure at the center can affect protection in every country designated through the Madrid filing.

The Madrid System Is Not One Worldwide Trademark

The Madrid System lets a trademark owner file one international application through WIPO and designate multiple Madrid member countries. It simplifies filing, renewals, certain recordals, and later management.

But it does not create one worldwide trademark.

Each designated country still examines the mark under its own national or regional law. A designated office may grant protection, issue a refusal, ask for changes to goods and services, or require local counsel to respond. This is why a Madrid filing should be understood as a centralized route to a bundle of country-by-country rights, not a single global registration.

For businesses still comparing filing options, iGERENT's guide on how to get an international trademark explains the broader international filing context.

Why the Basic Mark Matters So Much

The basic mark is the foundation of the Madrid filing. It may be a pending application or an existing registration, depending on the Office of origin and the filing strategy.

This creates a strategic question before filing internationally: is the basic mark strong enough to carry the international portfolio for five years?

Several issues can weaken that foundation:

• The mark is descriptive, generic, or weakly distinctive.
• The goods and services are too broad or vague.
• The basic application is still under examination and likely to receive objections.
• A third party is likely to oppose it.
• The basic mark covers goods or services that the business does not actually need.
• Ownership, renewal, or prosecution deadlines are not being carefully monitored.

Using a pending basic application can be efficient, but it can also increase risk. If the application is narrowed during examination, refused in part, opposed, or withdrawn, the international registration may have to follow that narrower path.

Central Attack Is Broader Than a Literal Attack

The phrase "central attack" sounds like a competitor must actively attack the basic mark. Sometimes that is exactly what happens. A third party may file an opposition or cancellation action against the home filing because it wants to collapse the Madrid portfolio linked to it.

But the risk is broader than that.

The international registration may be affected even when there is no dramatic courtroom battle. The basic mark can cease to have effect because of ordinary prosecution or portfolio events, including:

• Refusal by the Office of origin on absolute or relative grounds.
• Withdrawal or abandonment of the basic application.
• Narrowing of goods and services during examination.
• Non-renewal of the basic registration.
• Cancellation, revocation, or invalidation.
• Renunciation of the basic registration.

This is the part many SMBs miss. A Madrid portfolio can be damaged not only by an opponent's strategy, but also by a weak home filing, an overbroad specification, or missed administration.

Total vs. Partial Central Attack

Central attack can be total or partial.

A total central attack cancels the entire international registration. For example, if the basic application is finally refused for all goods and services within the dependency period, the international registration may be cancelled in full.

A partial central attack affects only part of the portfolio. For example, if the basic application originally covered "clothing" but is later narrowed to "casual pants and jackets," the international registration may also be narrowed across designated countries to reflect the reduced scope.

The commercial difference is huge. A total loss may require emergency filings in every important country. A partial loss may preserve the mark but remove the goods or services that mattered most to a planned launch.

Why the Five-Year Period Can Matter Even After Five Years

The international registration becomes independent from the basic mark after five years. That sounds reassuring, but timing needs careful attention.

If an opposition, cancellation, appeal, or court action started before the end of the five-year dependency period and later results in a final refusal, cancellation, revocation, or invalidation, the international registration can still be affected.

In practical terms, the risk does not always disappear on the fifth anniversary. A proceeding that began before that date can still produce consequences later.

That is especially important when acquiring a Madrid portfolio. Due diligence should not only ask whether five years have passed. It should also ask whether any relevant proceeding started during those five years and remains capable of affecting the basic mark.

What Happens Procedurally?

When the basic mark ceases to have effect in whole or in part, the Office of origin must notify WIPO's International Bureau. WIPO then records the cancellation or limitation in the International Register and notifies the holder and the designated offices.

For the holder, the practical result may be sudden and disruptive:

• The scope of the international registration may be narrowed.
• Protection in designated countries may no longer be available for affected goods or services.
• Local filing decisions may need to be made quickly.
• Budgets may shift from centralized Madrid management to separate national or regional filings.

This is why central attack is not just a legal concept. It can become an operations problem, a launch problem, and a budget problem at the same time.

Transformation: The Emergency Remedy

The Madrid Protocol includes an emergency mechanism called transformation.

If the international registration is cancelled because of central attack, the holder may file national or regional applications in the affected designated countries and keep the original international registration date or priority date, if the requirements are met.

Transformation is useful because it may preserve priority. But it is not a simple reset button.

Key limits include:

• The transformed applications generally must be filed within three months from the cancellation.
• The applications must be for the same mark.
• The goods and services must be covered by the cancelled international registration for the country concerned.
• Each national or regional office applies its own local rules.
• Local filing fees, local counsel, translations, and prosecution costs may apply.

Transformation can save a portfolio from total priority loss, but it is expensive and administratively heavy. For a business that designated many countries, it can turn one centralized filing into a fast, multi-country rescue operation.

Case Study: LEGO v. LEPIN and the Practical Limits of Central Attack

The LEGO v. LEPIN dispute shows why central attack is powerful in theory, but sometimes messy in practice.

According to the Kluwer Trademark Blog analysis of LEGO Juris A/S v. Shantou Chenghai Longjun Toy Factory, the LEPIN logo was filed in China and used as the basis for a Madrid international registration designating 47 countries. LEGO opposed the Chinese basic application. The opposition was upheld, a review was dismissed on May 24, 2019, and the decision reportedly became final in June 2019.

In theory, success against the Chinese basic mark should have triggered central consequences for the Madrid registration. The practical problem was procedural follow-through. The Kluwer analysis reported that the final decision had not been promptly reported to WIPO, meaning LEGO still had to continue challenging designations around the world despite having succeeded against the basic mark.

The lesson is not that central attack is useless. It is that central attack depends on procedure. A successful challenge against the basic mark may still require active monitoring, communication with the Office of origin, and continued local enforcement until WIPO records the relevant change.

For businesses defending a Madrid portfolio, the lesson is equally important: do not assume a problem is contained because it starts in one country. A basic mark dispute can become international quickly.

When the Madrid System Still Makes Sense

None of this means Madrid is a bad route.

For many businesses, the Madrid System remains efficient, especially when:

• The mark is distinctive and likely to survive examination.
• The basic mark is already registered or close to secure.
• The business wants protection in several Madrid member countries.
• Centralized renewal and portfolio management are valuable.
• The designated countries are commercially relevant but not all mission-critical.

The smarter conclusion is that Madrid should be used strategically. It is often excellent for broad expansion, but weaker as a one-size-fits-all answer where a few countries are so important that any loss of protection would be unacceptable.

Practical Ways to Reduce Central Attack Risk

Businesses can reduce central attack risk before filing, during the dependency period, and during portfolio transactions.

Before filing:

• Use a registered basic mark when possible, rather than relying only on a pending application.
• Choose a strong, distinctive mark that is likely to survive examination.
• Run clearance searches before filing the basic application.
• Avoid overbroad or vague goods and services.
• Align the basic mark with the goods and services that matter commercially.
• Consider direct national or regional filings in mission-critical countries.

During the first five years:

• Monitor the basic application or registration closely.
• Track office actions, oppositions, appeals, renewals, and ownership changes.
• Keep evidence of use where use may matter.
• Review any narrowing of goods and services for international impact.
• Prepare a transformation plan for high-value countries before a crisis.

When acquiring or auditing a portfolio:

• Check the international registration date.
• Confirm whether the five-year dependency period has expired.
• Review the status of the basic mark.
• Look for proceedings that began during the dependency period.
• Check whether any partial limitation has already affected the international registration.

The goal is not to eliminate every risk. The goal is to know where the dependency risk sits and decide whether Madrid, direct filings, or a hybrid strategy fits the business reality.

FAQ

What is central attack under the Madrid Protocol?

Central attack is the loss or limitation of an international registration because the basic application or basic registration fails during the five-year dependency period, or because a proceeding started during that period later produces a final adverse result.

Does central attack only happen when a competitor attacks the basic mark?

No. The term can be misleading. The same result can follow from refusal, withdrawal, abandonment, non-renewal, narrowing of goods and services, cancellation, revocation, invalidation, or renunciation of the basic mark.

What is transformation after a central attack?

Transformation lets the holder file national or regional applications in affected designated countries while keeping the original international registration date or priority date, if the requirements are met and the applications are filed within three months.

How can businesses reduce central attack risk?

Businesses can reduce risk by using a strong registered basic mark when possible, avoiding vague goods and services, monitoring the basic mark during the first five years, and considering direct filings in countries where protection is business-critical.
