Korean Office Action Response

SODAM prepares Korean office action responses by analyzing examiner reasoning, cited prior art, amendment options, translation consistency, and the applicant's commercial claim objectives.

Korean Office Action Responses: Key Points

The Notice of Grounds for Rejection

Before rejecting a Korean patent application, the examiner must notify the applicant of the grounds and set a period for submitting a written argument (Patent Act, Article 63(1)). Where the application has two or more claims, the notice must identify the rejected claims and state specific reasons for each (Article 63(2)). Examination is conducted by the Ministry of Intellectual Property (MOIP), the Korean patent office formerly known as the Korean Intellectual Property Office (KIPO). The response period is stated in the notice and may be extended on request (Article 15(2)), subject to MOIP rules; extension fees and the effect on later timing should be weighed when planning the response. Trademark and design applications follow a similar notice-and-response structure under their own statutes.

First and Final Notices: Different Amendment Limits

Korean practice distinguishes a first notice from a final notice. In response to a first notice, the applicant may amend the specification, claims, and drawings, provided the amendment stays within the matters described in the application as originally filed (Article 47(1) and (2)); for a foreign-language application, the final Korean translation is a further limit. A final notice is issued for new grounds caused by the applicant's own amendment, and claim amendments are then restricted to narrowing the claims, correcting clerical errors, clarifying unclear descriptions, or reverting an improper amendment (Article 47(3)). Identifying which type of notice has issued is therefore the first step in planning claim strategy.

Divisional Applications and Foreign Prosecution History

The response period is also one of the windows for filing a divisional application (Article 52(1)(i)); further windows open within three months after a decision of rejection or after a decision to grant, subject to the registration date (Article 52(1)(ii) and (iii)). Arguments that succeeded before other offices are useful background, but the Korean examiner applies Korean standards to the Korean claim wording, and statements made in a response can later be relied on when the claims are interpreted in an invalidation trial or an infringement dispute. SODAM therefore reviews foreign amendments and allowed claims against the Korean translation before proposing claim language, rather than carrying a foreign response over to Korea unchanged.

Key Issues We Review

  • Novelty, inventive step, clarity, support, unity, distinctiveness, or design registrability issues depending on the application type.
  • Korean amendment scope and consistency with the original disclosure.
  • Translation accuracy, claim terminology, and support in the Korean specification.
  • Potential effects on later invalidation, enforcement, or claim interpretation.

Documents and Information to Send

  • Office action, current claims, specification, drawings, and cited references.
  • Applicant instructions regarding commercially important features.
  • Foreign office actions, responses, amendments, and allowed claims where relevant.
  • Any proposed amendment or argument prepared by foreign counsel.
  • A signed power of attorney in favor of SODAM. An applicant with no domicile or place of business in Korea must act through a Korean patent administrator (Patent Act, Article 5).

Typical Stages and Deadlines

  1. Receipt. SODAM reports the notice in English with the deadline, the rejected claims, and an initial view of each ground.
  2. Strategy. Foreign counsel and SODAM agree on the arguments, any claim amendments, and whether a divisional application is needed.
  3. Filing. SODAM files the written argument and any amendment in Korean before the deadline, or requests an extension where needed.
  4. Next action. The examiner allows the application, issues a further notice, or issues a decision of rejection, after which re-examination or an appeal to the Board is available (Articles 67-2 and 132-17).

FAQ

Should foreign prosecution arguments be copied into Korea?
Not automatically. Korean examiner reasoning, cited references, claim language, and amendment constraints should be reviewed independently.
Can claim scope be preserved while responding?
Often, but the available path depends on the original disclosure, cited references, claim wording, and Korean amendment constraints.
Can SODAM review translation issues?
Yes. Translation consistency and terminology can affect examination, later amendments, and dispute positions, so they should be reviewed when material.
