Trademarks and service marks(Trademark hereinafter) may be protected in the Republic of  Korea under the Trademark Act. The use of a trademark is not a prerequisite for filing an application for the registration of a trademark. Unregistered marks are not protected under the Trademark Act, although the owner of a well-known or famous mark is given some protection under the Trademark Act by way of preventing others from obtaining a trademark registration for an identical or similar mark.
1. Filing an Application
Document Required

(a) an application stating the following: the name and address of the applicant (including the name of an executive officer, if the applicant is a juristic person); the trademark; the designated goods and class thereof; the date of submission; and the country and filing date of the priority application, if the right of priority is claimed;

(b) if the right of priority is claimed, the priority document; and

(c) a power of attorney, if necessary.
2. Formality Examination
When a Trademark application is submitted to KIPO, it is checked to ensure that all requirements necessary to accord the application a filing date have been satisfied.
3. Substantial Examination
Unlike patent or utility model applications, trademark applications are automatically examined in order of their filing date. No request for examination is needed for the initiation of substantial examination. Furthermore, the Trademark Act does not provide for the expedited examination system which is available for patent, utility model and design applications.
4. Publication and Pre-Grant Opposition
If the examiner finds no ground for rejection of a trademark application, or he considers that the rejection has been overcome by the applicant's response (argument and/or amendment), he shall render a decision to publish the trademark application.


Once a trademark application is published in the official gazette, called the "Trademark Publication Gazette," any person may file an opposition within two months from the publication date. The two months period cannot be extended. A notice of opposition containing a brief statement on the grounds for opposition must be submitted within the two months period. Then, the opponent may amend, add or supplement the grounds for opposition within 30 days after the expiration of the two months period.
5. Rejection, Registration, Appeal and Trial
Rejection, Registration, Appeal and Trial procedure is same with those of patent.
6. Renewal
The duration of the protection of a trademark right is 10 years from the date of registration of the trademark, which may be renewed every 10 years. For the renewal of a trademark registration, an application for the renewal should be filed with KIPO.
