Introduction

The system of international registration of marks is governed by two treaties: the Madrid Agreement Concerning the International Registration of Marks, which dates from 1891, and the Protocol Relating to the Madrid Agreement, which was adopted in 1989, entered into force on December 1, 1995, and came into operation on April 1, 1996. Common Regulations under the Agreement and Protocol also came into force on that date. The system is administered by the International Bureau of WIPO, which maintains the International Register and publishes the WIPO Gazette of International Marks.
Members
Till January 15, 2014, in total 92 states become party to Madrid Union. 
Who May Use the System
An application for international registration (an “international application”) may be filed only by a natural person or a legal entity which has a real and effective industrial or commercial establishment in, or is domiciled in, or is a national of China, or who has such an establishment in, or is domiciled in, the territory of an intergovernmental organization which is a party to the Protocol, or is a national of a Member State of such an organization.
The Madrid system of international registration cannot be used by a person or legal entity which does not have the necessary connection, through establishment, domicile or nationality, with a member of the Madrid Union. Nor can it be used to protect a mark outside the Madrid Union.

Examination and Refusal of Protection

The Office of a designated Contracting Party examines the international registration in exactly the same way as an application filed directly. If grounds for objection are found during the ex officio examination, or if an opposition is filed, the Office has the right to declare that protection cannot be granted to the mark in that Contracting Party.
Any provisional refusal must be notified to the International Bureau by the Office of the Contracting Party concerned within the time limit specified in the Agreement or Protocol. This standard time limit is 12 months. A Contracting Party may however declare that, when it is designated under the Protocol, this time limit shall be replaced by 18 months. A Contracting Party that has made this declaration may further declare that a provisional refusal based on an opposition may be notified even after the expiry of this 18-month period.
Required Documents:
1,Mark logo
2,POA (signed and stamped by the applicant)
3,Copy of <trademark registration certificats > or <trademark filing receipts> from Chinese IPO
4,Copy of Business License or identification card
5, If there are change, assign or renewal regarding basic registration or application in domestic, copies of the prove documents shall submit the same.

Advantages of the System

International registration has several advantages for the owner of the mark. After registering the mark, or filing an application for registration, with the Office of origin, he has only to file one application, in one language, and pay one fee instead of filing separately in the trademark Offices of the various Contracting Parties in different languages and paying a separate fee in each Office. Moreover, the holder does not have to wait for the Office of each Contracting Party in which protection is sought to take a positive decision to register the mark; if no refusal is notified by an Office within the applicable time limit, the mark is protected in the Contracting Party concerned. In some cases, the holder does not even have to wait the expiry of this time limit in order to know that the mark is protected in a Contracting Party, since he may, before the expiry of the time limit, receive a statement of grant of protection from the Office of that Contracting Party.
A further important advantage is that changes subsequent to registration, such as a change in the name or address of the holder, or a change (total or partial) in ownership or a limitation of the list of goods and services may be recorded with effect for several designated Contracting Parties through a single simple procedural step and the payment of a single fee. Moreover, there is only one expiry date and only one registration to renew.
International registration is also to the advantage of Trademark Offices. They do not need to examine for compliance with formal requirements, or classify the goods or services, or publish the marks. Moreover, they are compensated for the work that they perform; the individual fees collected by the International Bureau are transferred to the Contracting Parties in respect of which they have been paid, while the complementary and supplementary fees are distributed annually among the Contracting Parties not receiving individual fees, in proportion of the number of designations made of each of them.
