Korean trademark application procedures are divided into formal examination and substantive examination:

Formal examination: the applicant submits the trademark application documents to the trademark registration office, and the trademark registrar examines the legality of the submitted application documents, trademark drawings, power of attorney and other related documents; Trademark documents that pass the examination will be awarded the application date and application number.

substantive examination: the trademark registrar examines the trademark itself to see whether the trademark conforms to the legal provisions and whether it is the same as or similar to the trademark applied for earlier. After the substantive examination is passed, the Intellectual Property Office will issue a notice of approval to the trademark that conforms to the law, and the trademark that has obtained the notice will be published in the official announcement. If no objection is raised within 31 days, the trademark will be approved for registration and a trademark registration certificate will be issued.
