What is Madrid Protocol?

International5 min readUpdated Mar 25, 2026

An international treaty that enables trademark owners to seek protection in multiple countries through a single application filed via WIPO.

The Madrid Protocol, formally known as the Protocol Relating to the Madrid Agreement Concerning the International Registration of Marks, is an international treaty administered by the World Intellectual Property Organization (WIPO) that provides a centralized system for registering trademarks in multiple countries through a single application. Adopted in 1989 and entering into force in 1996, it has become the primary mechanism for international trademark protection, with over 110 contracting parties covering the vast majority of the world's major commercial markets.

Under the Madrid Protocol, a trademark owner who has filed or registered a mark in their home country (the "office of origin") can file an international application through that office, designating any number of member countries where they seek protection. WIPO conducts a formal examination of the international application and, if it meets the requirements, registers the mark on the International Register and notifies each designated country. Each designated country then examines the application according to its own national law and has a defined period (typically 12 or 18 months) to refuse protection. If no refusal is issued within that period, the mark is protected in the designated country as if it had been registered directly with the national office.

The Madrid Protocol offers several advantages over filing separate national applications in each country. It consolidates the filing process into a single application, in a single language, with a single set of fees payable to WIPO. It also provides a centralized management system for renewing, recording changes, and expanding protection to additional countries throughout the life of the registration.

Why It Matters

For businesses operating internationally or planning to expand across borders, the Madrid Protocol dramatically simplifies and reduces the cost of building a global trademark portfolio. Without it, seeking protection in, say, 20 countries would require engaging local counsel in each jurisdiction, filing 20 separate applications in up to 20 different languages, and managing 20 distinct registration timelines and renewal deadlines. The complexity and expense of this process can be prohibitive, particularly for small and medium enterprises.

The Madrid Protocol makes international protection accessible by allowing a single filing to cover multiple jurisdictions simultaneously. The cost savings are significant, as WIPO's fee structure is generally lower than the combined cost of individual national filings, and the reduction in administrative overhead further reduces the total cost of building an international portfolio.

However, the Madrid Protocol has important limitations that brand owners must understand. The most significant is the "central attack" vulnerability: during the first five years, the international registration is dependent on the home registration. If the home registration is cancelled or narrowed for any reason, the international registration is affected correspondingly in all designated countries. After five years, the international registration becomes independent of the home registration. Additionally, not all countries are members of the Madrid Protocol, and designated countries retain the right to refuse protection based on their national examination standards.

How Signa Helps

Signa provides comprehensive support for Madrid Protocol filings through its API, offering access to trademark data across 200+ offices including WIPO and all major Madrid Protocol member countries. Before filing an international application, brand owners can use Signa's search capabilities to conduct clearance searches in each target jurisdiction, identifying potential conflicts that could lead to refusals.

After filing, Signa's monitoring service tracks the status of the international registration and its designated country protections, alerting brand owners to refusals, oppositions, or other actions that require a response. This is particularly valuable because the consequences of missing a response deadline in a designated country can be the loss of protection in that market.

Signa's data also enables brand owners to monitor the Madrid Protocol activity of competitors and potential infringers, providing intelligence about where competitors are seeking protection and whether any conflicting international registrations are being filed.

Real-World Example

A Danish design studio has successfully registered its furniture brand in Denmark and wants to expand sales to the United States, Japan, China, Australia, and the United Kingdom. Rather than engaging local trademark attorneys in each country and filing five separate applications, the studio files a single international application under the Madrid Protocol through the Danish Patent and Trademark Office, designating all five target countries.

WIPO registers the mark on the International Register and notifies each designated office. Over the following months, four of the five countries accept the protection without objection. China issues a provisional refusal based on a similar existing registration for related goods. The studio's attorney responds to the refusal with evidence of the mark's distinctiveness and the differences from the cited registration, and after examination, the Chinese office grants protection.

The entire process is managed through a single international registration, with one renewal date and centralized recordal of any changes. The studio estimates that the Madrid Protocol route saved approximately 40 percent in filing costs and significantly reduced the administrative burden compared to filing separate national applications in each country.
