Substantial examination shall be applied only to a trademark application that passes the formality examination. The substantial examination procedure considers all absolute and relative reasons for rejection.

When the examiner finds no grounds for rejection, the trademark application concerned is published in the Korean Trademark Gazette. When there is a reason for rejection, the applicant is entitled to a notification of the reasons for refusal and given an opportunity to submit a written statement of arguments against the reasons for refusal.
Within 30 days from the trademark publication date, any third party can file an opposition to the published mark. Once an opposition is filed, the trademark applicant is notified and will then be given an opportunity to file a response to the opposition.
It generally takes about 8 to 10 months from the filing date of a trademark application to receive an official communication from the examiner. Accordingly, a trademark registration may be granted within 12 to 15 months unless a further official action or opposition delays the process.
The term of a registered trademark is 10 years and may be renewed every 10 years.
