Overview
Trademarks, and service (Trademark hereinafter) marks may be protected in the Republic of Korea under the Trademark Act; and for such protection, marks should be registered with the Korean Intellectual Property Office ("KIPO"). 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. There is no course of action against infringement of a well-known or famous unregistered trademark under the Trademark Act, but an action may be brought under the Unfair Competition Prevention Act.

* Filing an Application
(i) ApplicantAny person who uses or intends to use a trademark in the Republic of Korea may file an application for the registration of a trademark. Although the Korean Trademark Act adopts a registration system, not a use system, the applicant of a trademark application should have a bona fide intent to use his trademark in the Republic of Korea. Nonetheless, trademarks which will not actually be used are also registered. Such trademarks, however, will be subject to cancellation if they remain unused for three or more consecutive years after their registration.
(ii) Document RequiredFor a trademark application, the following documents should be submitted to KIPO:
(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) 10 specimens of the trademark (8cm x 8cm or smaller in size);
(c) if the right of priority is claimed, the priority document; and
(d) a power of attorney, if necessary
Only document (a) must be submitted at the time of filing the trademark application. The name of an executive officer of the applicant may be added later on the applicant's own initiative or in response to a notice of amendment issued from KIPO.
If the applicant fails to submit specimens of the trademark or power of attorney at the time of filing the trademark application, KIPO will issue a notice of amendment requesting the applicant to submit them, designating a time limit thereof. The priority document must be submitted within 3 months from the filing date in the Republic of Korea of the trademark application. This time limit cannot be extended
(iii) Designation of Goods/Services: Nice Classification
A person who desires to file a trademark application must designate goods/services on which the trademark is to be used in accordance with the Nice Classification of Goods or Services for the Purpose of Registration of Marks. The Republic of Korea adopted the Nice Classification as of March 1, 1998.

* Formal Examination
According to Article 2(1) of the Enforcement Regulation of the Trademark Act, the application will be returned to the submitter without any application number being assigned thereto and will be treated as if it had never been submitted in any of the following circumstances:
(i) where the kind of the application is not clear;
(ii) where the name or address of a person (or juristic person) who takes the procedure (i.e. the applicant) is not described;
(iii) where the application is not written in Korean;
(iv) where a specimen of the trademark is not attached to the application paper;
(v) where the designated goods/services are not described in the application paper; or
(vi) where the application is submitted, by a person who has no address or place of business in the Republic of Korea, without coming through a patent agent in the Republic of Korea.
Once the application has satisfied such requirements, KIPO assigns an application number and examines as to whether or not other formality requirements under the Trademark Act have been met. If anything is found missing or wrong, the Commissioner of KIPO will issue a notice of amendment requesting the applicant to supplement the missing data or amend it, and within specified a time limit. If the applicant does not comply with such request, the trademark application will be nullified.
