Essential Guide to Trademarks in South Korea
Protecting Your Application with Brealant's Expertise

Legal Definition of a Trademark Office Action
A Notice of Preliminary Rejection is issued under the Trademark Act of Korea when a KIPO examiner identifies grounds for refusing an application, whether on absolute or relative grounds.
Purpose and Function of an Office Action
The notice gives you the chance to address the examiner's concerns — commonly a conflicting prior mark, lack of distinctiveness, or a classification issue — before a final refusal decision is issued.
Protecting Your Application
A well-argued response can resolve objections while preserving the broadest possible scope of protection for your brand, rather than conceding more than necessary.

Clear, Simple Steps to Overcome Your Office Action
In South Korea, a Notice of Preliminary Rejection sets out precisely why KIPO's examiner considers your application doesn't yet meet the requirements of the Trademark Act of Korea. Understanding exactly which ground has been raised — conflict with an earlier mark, lack of distinctiveness, or a classification issue — is the clearest way to build an effective response.
Safeguarding Your Application in South Korea — With Brealant by Your Side
An office action isn't a final rejection — it's an opportunity to persuade the examiner. Brealant's response strategy is built to resolve the objection while safeguarding the commercial value of your mark, rather than narrowing it more than necessary.
Limitations
What an Office Action Response Cannot Fix
A response is powerful, but it has boundaries applicants should understand
Fundamental Conflicts
A response can't remove a genuinely conflicting earlier mark from the KIPRIS register.
Missed Deadlines
Once the response deadline passes without a satisfactory response, the application proceeds to a final refusal decision.
Inherent Descriptiveness
Some marks are too descriptive to overcome through argument alone, without evidence of acquired distinctiveness through use.
New Grounds
A response can't pre-empt grounds the examiner hasn't yet raised, such as a later opposition.
Guaranteed Outcomes
No response guarantees acceptance — the examiner retains discretion on the final decision.
Brealant will give you a realistic assessment of your prospects before you commit to a response strategy.
What a Office Action Response Protects
A properly prepared office action response protects several things at once
Your Filing Date
Timely responses keep your original filing date and priority intact under Korea's first-to-file system.
Your Scope of Protection
Careful argument can avoid unnecessary narrowing of your goods and services.
Your Brand Elements
Evidence of use and distinctiveness can support keeping your mark as originally filed.
Your Investment
A resolved objection protects the time and cost already spent preparing your application.
Brealant's attorneys assess every option before recommending the response most likely to succeed.
Timeline for a Trademark Office Action in South Korea

Responding to an office action generally follows these stages
Notice Issued
KIPO issues the Notice of Preliminary Rejection once its examiner completes substantive examination and identifies grounds for refusal.
Response Preparation
Brealant prepares submissions, evidence, or amendments to address the objections raised.
Filing the Response
The response is lodged with KIPO before the statutory deadline.
Further Rejection or Acceptance
KIPO either accepts the application or issues a final rejection if the objections aren't resolved.
Applicants generally have two months from the notice date to respond, with extensions available on request, before a final refusal decision issues.
Understanding Office Action Costs in South Korea — Simplified with Brealant
Costs for an office action response depend on the nature of the objection
Official Filing Fees
KIPO charges no separate fee to file a response itself, though a modest official fee applies if you request an extension of the response deadline.
Professional fees
Brealant charges a fixed professional fee for preparing and filing the response, scaled to the complexity of the objection.
We quote this upfront once we've reviewed your examination report, so there are no surprises.

Frequently Asked Questions
Can I amend my application to overcome an objection?
In many cases yes — narrowing the goods/services list or amending non-substantive elements of the mark can resolve certain objections.
What happens if I don't respond to an office action in South Korea?
If the deadline passes without a response that satisfies the examiner, KIPO issues a final refusal decision and the application does not proceed to registration.
Can the response deadline be extended?
Yes, extensions are generally available on request, typically in additional one-month increments, subject to a modest official fee.
Can I appeal if KIPO issues a final refusal?
Yes, applicants can file an appeal with Korea's IP Trial and Appeal Board if the objection isn't resolved through the written response.
How long do I have to respond to a trademark office action in South Korea?
Applicants generally have two months from the date of the notice to respond, with extensions available on request.
Is there a difference between a preliminary refusal and a final refusal?
Yes — a preliminary refusal gives you the chance to respond and potentially overcome the objection, while a final refusal is issued only if the examiner remains unconvinced after that response.
What are the most common grounds for a preliminary refusal in South Korea?
Conflict with an earlier identical or similar mark, descriptiveness or lack of distinctiveness, and marks considered misleading or contrary to public order are among the most frequent grounds an examiner cites.
Can I submit evidence of acquired distinctiveness to overcome an objection?
Yes, in some cases evidence showing the mark has become distinctive through use in Korea can help overcome a descriptiveness objection, though the threshold for this evidence is fairly demanding.
How much does it typically cost to respond to an office action?
Cost depends on the complexity of the objection and the strength of the argument or amendment needed, and Brealant quotes this for your specific case before work begins.
Does responding to a KIPO office action require a Korean trademark attorney?
Foreign applicants must respond through a Korea-based trademark attorney or agent, which is one reason Brealant coordinates the response together with local counsel.
