Korea is the world's fifth-largest patent applicant jurisdiction. KIPO (Korean Intellectual Property Office) processes more than 200,000 patent applications annually, with examination quality and efficiency that rank among the best globally. Yet many international IP firms' understanding of Korean practice stops at "refer the matter to a local Korean firm," with little grasp of what a 변리사 (Korean patent attorney) actually does day to day.

That knowledge gap carries real costs: missing the strategic window opened by the 분리출원 (Separated Application) institution introduced in April 2022, overlooking the 우선심사 (Priority Examination) expansion to 11 technology categories in February 2025, or miscalculating the 31-month PCT national phase deadline instead of 30 months.

This article reconstructs the complete 변리사 workflow from 발명신고서 (Invention Disclosure Form) to 특허로 submission, drawing on KIPO official guidance, PCT WIPO eGuide (Korea section), Kim & Chang IP practitioner documents, Pine IP materials, and the ICLG 2026 Korea chapter.

Target readers: International IP firm partners who need a systematic grasp of Korean practice; corporate IP directors responsible for cross-border patent strategy; Korean 변리사 professionals seeking to benchmark best practices.

1. Complete Filing Document Checklist

Korean patent filings fall into three tiers: always-required documents, conditionally-required documents triggered by specific circumstances, and optional documents.

Mandatory Documents (5 items)

No.	Document Name	Role	Notes
1	특허출원서 (Patent Application Form)	Main form: applicant, inventor, 발명 명칭, etc.	Contains PII (name, address, 법인번호/주민번호)
2	명세서 (Specification)	Core document recording the technical content of the invention	May be filed in English first; Korean translation due within 14 months
3	청구범위 (청구항) (Claims)	The core legal document defining the scope of patent protection	File at application or up to 14 months later
4	요약서 (Abstract)	Technical summary ≤200 Korean characters for KIPRIS publication	Non-sensitive; drafted by 변리사
5	도면 (Drawings)	Required if claims reference drawings; optional otherwise	File at application or supplement within 2 months

Conditionally Mandatory Documents (13 items triggered by circumstances)

No.	Document Name	Trigger	Deadline
6	대리인 위임장 (Power of Attorney)	Foreign applicant or corporate applicant engaging a 변리사	At filing or can be supplemented later
7	우선권 증명서류 (Priority Documents)	Paris Convention priority claim	Within 16 months from earliest priority date (waived via DAS for USPTO/JPO/EPO/CNIPA)
8	국내우선권 주장서 (Domestic Priority Claim)	Priority claim based on earlier domestic application (특허법 제55조)	Arises automatically if later application filed within 1 year of earlier application
9	외국어 명세서 번역문 (Foreign Language Translation)	English-language application filed first	Within 14 months of filing date
10	서열목록 (Sequence Listing)	Nucleic acid/protein sequence inventions	File simultaneously, XML format (WIPO ST.26)
11	공지예외주장 신청서 + 증명서 (Grace Period Claim + Certificate)	Pre-filing disclosure of the invention (특허법 제30조)	Request at filing or within amendment period; certificate within 30 days of filing

18	대표도 지정서 (Representative Drawing Designation)	Explicitly designating a representative drawing (optional)	At filing

Electronic filing practice: Korean patents are submitted through 특허로 (patent.go.kr). Applicants must first obtain a 특허고객번호 and register a 공동인증서. Electronic filing fee: 46,000 KRW; paper filing: 66,000 KRW. Documents are prepared in NKeditor or Web tools in XML/Korean format.

2. The 변리사 Claims First Drafting Workflow (10-Step Timeline)

Korean 변리사 practice aligns closely with US practice in following a Claims First (청구항 우선) approach. Below is the complete 10-step workflow from 발명신고서 receipt to 특허로 submission.

Phase	Steps	Typical Timing	Primary Output
Phase 0: Pre-Filing Preparation	Steps 1–3	D-30 to D-15	IDF analysis, prior art search report, filing strategy
Phase 1: Interview & Information Gathering	Step 4	D-14 to D-7	Inventor interview record, PII collection
Phase 2: Claims Drafting	Steps 5–6	D-7 to D-3	Independent + dependent claim draft, client review
Phase 3: Specification Drafting	Step 7	D-3 to D-1	Complete specification
Phase 4: QC + Filing	Steps 8–10	D-1 to D-Day	특허로 submission, application number receipt

Step 1: Receive and Analyze the 발명신고서 (Invention Disclosure Form)

The IDF is the workflow's starting point. The first task after receipt is to identify the technical core—not to begin drafting. Key questions at this stage:

Does the core technical feature satisfy 신규성 (novelty) and 진보성 (inventive step) under 특허법 제29조?
Are there § 101-equivalent risks (software, business methods)?
Does the inventor's timeline reveal any prior disclosures triggering a 공지예외주장 (Grace Period claim) obligation?
Would 실용신안 (Utility Model) be a better fit than 특허?

Output: Internal analysis memo; list of questions to resolve in the inventor interview.

Step 2: 선행기술 검색 (Prior Art Search)

Database	Notes
KIPRIS (kipris.or.kr)	Domestic patent search; most authoritative KIPO public database
USPTO / Google Patents	US patent families for cross-reference
Espacenet	European patents, PCT search
J-PlatPat	Japanese patent comparison

The search results enable a preliminary assessment of 신규성 and 진보성 prospects, culminating in a 조사결과보고서 (search report).

Step 3: Filing Strategy Confirmation

Discuss and confirm with the client: 특허 vs 실용신안 choice; priority jurisdictions and timeline (KR only / PCT / Paris Convention route); number and scope of claims; whether to request 조기공개 (early publication); and whether the invention falls within the 우선심사 11 technology categories (see Section 4).

Step 4: 발명자 인터뷰 (Inventor Interview)

This is the highest-information-density step in the entire workflow. The 변리사 must systematically collect:

Inventor and Applicant Information (includes PII): Full name, 주민등록번호 (passport number for foreign inventors), address, nationality, institutional affiliation of all inventors; applicant type (법인/개인/중소기업/스타트업)—directly affects fee reductions; confirmation of employee invention assignment agreement (post-August 2024 amendment: automatic assignment if succession clause exists).

Technical Content: Core technical features; primary and alternative embodiments; key technical effects; drawing list.

Disclosure History and Timeline: Date of first completion; dates of any paper publication, conference presentation, or exhibition (for 공지예외주장 assessment); whether competing products are already on the market.

Government R&D Project: Whether this is a government-funded invention (기술이전법 제11조의2 notation obligation).

Output: Interview record; initial citation list analogous to an IDS; confirmed applicant information sheet.

Step 5: 독립청구항 초안 (Independent Claim Drafting)

This is the core of the Claims First workflow. Korean 변리사 draft in the following sequence:

Independent claim (독립항) first draft—covering only the core inventive features, as broadly as possible. Transition phrase options:
- "…을 포함하는 [물건/장치/방법]" — Open-ended (equivalent to "comprising"); broadest protection scope
- "…을 특징으로 하는 [물건/장치]" — Traditional Korean expression; may be interpreted more narrowly
- "…로 이루어진" — Closed-ended (equivalent to "consisting of"); narrowest scope
物件 claims + 방법 claims + 시스템 claims—drafted by category, since KR recognizes independent claims per category; recommended to cover all simultaneously.
종속항 (Dependent claims)—beginning with "제N항에 있어서," to reference prior claims, adding specific numerical values, materials, or structural elements.
다항인용다항 금지 rule check (critically important; see Section 3).

Output: Draft claims; send to client for review to confirm the protection scope covers the core innovation.

Step 6: Claims Finalization

Send the draft to the inventor/client to verify: technical accuracy; whether actual embodiments fall within the protection scope; whether important alternative embodiments have been omitted. Once confirmed, the claims are finalized.

Step 7: 명세서 작성 (Specification Drafting)

After the claims are finalized, drafting of the specification begins. Standard Korean 명세서 structure (별지 제15호서식):

Section	Key Content
【발명의 명칭】	Title of invention
【기술분야】	Technical field (단락번호 starts at 【0001】)
【발명의 배경이 되는 기술】	Background technology and prior art problems
【발명의 내용】	Invention content (heading only; no 단락번호)
【해결하려는 과제】	Technical problem to be solved
【과제의 해결 수단】	Solution means (corresponding to the claims)
【발명의 효과】	Technical effects and advantages
【도면의 간단한 설명】	Brief description of drawings
【발명을 실시하기 위한 구체적인 내용】	Detailed embodiment description
【청구범위】	Claims (separate section; no 단락번호)
【요약서】	Abstract (≤200 characters + representative claim)
【도면】	Drawing attachments

Step 8: 내부 QC 검토 (Internal Quality Control)

Critical pre-submission checklist:

청구항–명세서 term consistency (특허법 제42조 제4항 제1호: written description support requirement)
Verify 단락번호 completeness (【0001】 sequence integrity)
다항인용다항 금지 check (enforced since April 22, 2022)
한자/영문 병기 consistency
Confirm 대표도 designation

Step 9: 특허로 System Submission (Electronic Filing)

Upload via patent.go.kr: 출원서 + 명세서 (including 청구범위) + 요약서 + 도면 in XML format. Pay fees online and receive the 접수번호 (application number).

Step 10: Post-Filing Client Notification

Notify the client of: filing date (기준일) and application number; and subsequent key dates—scheduled publication date (18 months), 심사청구 3-year deadline, and PCT downstream timing.

3. Korea's Four Unique Drafting Format Requirements

These are the most distinctive differences between Korean patent practice and that of the US or Japan. Every practitioner involved in KR patent drafting must master all four.

1. 격식체 (Formal Register)—Mandatory Writing Style

Korean patent specifications use 공문서 격식체 (formal official document register) throughout:

Context	Correct Format	Incorrect Format
Specification narrative	`~한다`, `~이다`, `~된다`, `~있다`	`~합니다`, `~했다`, colloquial contractions
Claim ending (物件/Apparatus)	`…을 포함하는 XX` or `…로 이루어진 XX`	`…를 포함합니다`
Claim ending (Method)	`…하는 것을 특징으로 하는 방법` or `…하는 단계를 포함하는 방법`	`…하는 방법입니다`
Dependent claim reference	`제N항에 있어서,`	`제N항을 인용하며,`

2. 단락번호【0001】—Paragraph Numbering Rules

Rule	Detail
Scope of application	Every paragraph from the first paragraph of 【기술분야】 through 【서열목록 자유텍스트】
Format	Fullwidth brackets (전각 대괄호): `【0001】`, 4-digit Arabic numerals; ASCII `[ ]` not permitted
Section headings	Major headings such as 【발명의 내용】 and 【도면의 간단한 설명】 receive no paragraph number
Claims	Individual claims receive no paragraph number
Amendment rule	Existing numbers must be preserved; new paragraphs appended at the highest existing number+1; mid-sequence insertion not permitted
Legal significance	Used during examination to pinpoint amendment targets in OA responses

3. 한자/영문 병기 (Parallel Chinese Character/English Notation)

On the first occurrence of a technical term, use the following formats:

Chinese character notation: 반도체（半導體）, 광섬유（光纖維）
English notation: 인공지능（AI, Artificial Intelligence）, DRAM（Dynamic Random Access Memory）
Combined: 딥러닝（deep learning）

On subsequent occurrences, use only the Korean term without repeating the parallel notation. Already-naturalized loanwords (컴퓨터, 인터넷) may omit notation. Although not legally mandated, this convention is referenced in KIPO examination guidelines and court term-clarity assessments.

4. 다항인용다항 금지 (Multi-Multi Dependency Prohibition)

This is the April 20, 2022 rule change most likely to catch international practitioners off-guard:

Rule: A dependent claim that references multiple prior claims (a "multi-dependent claim," e.g., "제1항 또는 제2항에 있어서") cannot be referenced by another dependent claim using a multi-reference format (e.g., "제1항 내지 제4항 중 어느 한 항에 있어서").

In brief: A multi-dependent claim cannot itself serve as the basis of a further multi-reference dependency.

How to handle it: Expand multi-dependent claims into individual single-reference dependent claims, or redesign the claim hierarchy to avoid the violation.

4. Korea-Specific Patent Institutions

분할출원 vs 분리출원 (Divisional vs Separated Application, 2022 New Institution)

Comparison	분할출원 (특허법 제52조)	분리출원 (특허법 제52조의2, Effective April 2022)
When to file	While parent application is pending (before first OA, during OA response period, after final rejection, within 3 months before registration fee payment)	Within 30 days of the day the 특허심판원 dismissed the appeal against rejection
Prerequisite	None	Only some claims rejected; not applicable if all claims rejected
Purpose	Unity of invention violations; broader claims; strategic timing spread	Secure rights on non-rejected claims after appeal loss
Further splitting	Can divide again from a divisional application	Cannot further split/divide/convert from a separated application

Strategic selection:

Before appeal (while application is pending): use 분할출원
After losing an appeal: use 분리출원 to secure rights on non-rejected claims
Preventive strategy: file divisional applications in parallel with appeals; if appeal is lost, the pending divisional keeps the option alive

우선심사 11 Categories (Expanded February 19, 2025)

Fee for 우선심사 application: 200,000 KRW. After approval, expected time to first OA: approximately 2–4 months (vs. 12–16 months for standard examination).

No.	Technology Category	Content
1	AI (인공지능)	Applications where AI technology is the primary CPC classification
2	Biotech (바이오 기술)	Biotechnology-related primary classifications
3	Advanced Robotics (첨단 로봇)	Advanced robotic technologies
4	Semiconductors (반도체)	Materials/components/equipment/manufacturing/design (expanded 2025)
5	Display (디스플레이)	Display technologies
6	Secondary Batteries (이차전지)	Materials/components/equipment/manufacturing/BMS/recycling (expanded 2025)
7	Hydrogen Economy (수소경제)	Hydrogen/ammonia, next-generation nuclear (SMR), advanced mobility (EV/hydrogen vehicles)
8	Carbon Neutrality/Green Tech (탄소중립/녹색기술)	Renewable energy (solar/wind/hydro/tidal/geothermal) + green-certified technologies
9	SMEs (중소기업)	Inventions that SMEs are practicing or preparing to practice
10	Startups (스타트업)	Companies within 3 years of founding
11	National Strategic Technologies (국가전략기술)	Government R&D project outputs; specialized research institution applications

심사청구 3-Year Deadline (Enforced since March 2017)

Deadline: Within 3 years of filing date (or international filing date) for applications filed on or after March 1, 2017 (prior applications: 5 years)
Consequence if missed: Application deemed withdrawn (취하 간주); automatically extinguished
심사청구료: Base 166,000 KRW + 51,000 KRW per claim (standard applicant); SMEs/individuals receive a 70% reduction
Strategy: File 심사청구 simultaneously with the application when rapid rights acquisition is needed; time it strategically within the 3-year window when monitoring competitive technology

실용신안 vs 특허 Selection

Comparison	특허	실용신안
Protected subject matter	Devices, methods, systems	Devices (articles) only—method applications not accepted
Requirements	신규성 + 진보성 + 산업상 이용가능성	신규성 + 산업상 이용가능성 (lower inventive step threshold)
Examination	Substantive examination	Formal examination → registration; substantive assessment via 기술평가서 system
Protection period	20 years from filing date	10 years from filing date
심사청구료	Base 166,000 KRW + 51,000 KRW/claim	Base 71,000 KRW + 19,000 KRW/claim (cheaper)
변리사 selection guide	Core original technology; method claims needed; long-term protection	Improvement technology; fast registration; method claims unnecessary; cost savings

PCT National Phase Entry (31-Month Deadline)

Item	Detail
National phase entry deadline	31 months from earliest PCT priority date (특허법 제199조; PCT Art. 22(3))
Translation filing	Korean translation (specification, claims, drawing text, abstract) must be filed by the 31-month deadline
심사청구	Within 3 years of international filing date (same as domestic applications)
Rights recovery	KIPO does not accept national phase deadline extensions or rights recovery requests (unlike US and JP—no remedy available)
Fee reduction	If KIPO was the International Searching Authority, 심사청구료 reduced 70%
Translation caution	Translation exceeding scope of original text triggers amendment order; translation errors are the applicant's responsibility

외국어서면출원 (English-First Filing, 특허법 제42조의3)

Permitted language: English (Korea accepts English-language specifications directly)
Filing date secured: Filing with an English specification secures the Korean filing date
Translation filing: Korean translation due within 14 months of filing date; failure to file results in deemed withdrawal (취하 간주)
Translation status: The translation serves as the Korean specification; amendment scope is determined based on the translation (Korean text)
Strategic use: When urgently needing to secure a filing date, file in English first → complete Korean translation within 14 months

PPH (Patent Prosecution Highway)

KIPO's PPH network covers USPTO, JPO, EPO, and CNIPA (IP5 PPH), plus Vietnam and most Global PPH members.

PPH outcomes: Fee 200,000 KRW; processing ~5 months (vs. ~21 months standard); allowance rate 89% (vs. 66% standard); over 30% of PPH cases allowed after just one OA.

PPH requirements: Foreign office has allowed at least one claim; Korean claims are the same or narrower than the allowed foreign claims; 심사청구 is complete.

12-Month 공지예외 (Grace Period) and Mandatory Explicit Claim

Comparison	Korea (KR)	United States (US)	Japan (JP)
Period	12 months	12 months	12 months
Claim method	Must explicitly claim; submit request at filing or within amendment period; certificate within 30 days of filing	Post-AIA: automatic application, no explicit claim needed	Written submission at filing + certificate within 30 days
Applicable disclosures	Only the applicant's own disclosures (third-party disclosures excluded)	Disclosures by inventor or those who obtained from inventor	Disclosures by the person entitled to obtain the patent
Risk	Failure to claim: your own disclosure counts as prior art	Automatic protection	Various exceptions apply

5. Korean Patent Act Key Provisions Quick Reference

우선심사 application fee	200,000 KRW	60,000 KRW	—
PPH application fee	200,000 KRW	60,000 KRW	No PPH fee

7. AI Tool Positioning in the Korean 변리사 Workflow

Based on a deep review of KIPO practice, here is a precise delineation of what AI tools can and cannot do in a 변리사's workflow.

Where AI Can Provide Deep Assistance

Function	Description	Priority
명세서 기재요건 verification	Automated check of 특허법 제42조 제3항 (실시가능) and 제4항 제1호 (뒷받침) compliance	Core
격식체 consistency check	Verify `~한다`/`~이다` formal endings throughout; claim ending format consistency	Core
한자/영문 병기 auto-suggestion	On first occurrence of technical terms, suggest parallel Chinese/English notation; warn on redundant repetition	High
다항인용다항 detection	Automatically detect and flag dependent claims that violate the multi-multi prohibition	Core
단락번호【0001】auto-insertion	Sequentially number every paragraph of the specification; enforce fullwidth bracket format	Core
대표도 selection guidance	Recommend the optimal representative drawing by invention type (flowchart vs. block diagram)	High
우선심사 eligibility diagnosis	Automatically assess whether the technical field falls within the 11 priority examination categories	High
분리출원 vs 분할출원 decision support	Guide strategic option selection based on current stage (pending vs. post-appeal)	Medium
Fee calculation (2025 schedule)	Compute 심사청구료 based on claim count; apply entity-tier reductions	Medium
공지예외주장 check	Based on disclosed history, flag Grace Period claim requirement and deadline	High
PCT 31-month deadline calculator	Auto-calculate national phase entry deadline from priority date	High
Term consistency check	Verify that the same component uses identical terminology across specification and claims	Core

What AI Must Not Touch (변리사-Exclusive Domain)

Task	Reason
Inventor signatures / original power of attorney	Legal signature act; 변리사 must perform directly
Original SME certificate / startup certificate submission	Direct transaction with issuing authority; official documents
Official 특허로 submission using account credentials	Certificate-based electronic filing; performed by 변리사 or applicant directly
Storing/processing inventor PII (주민번호, etc.)	Subject to Korean Personal Information Protection Act
Employee invention compensation calculation / rights determination	Legal judgment; 변리사/법률가 domain
Patent validity opinions (FTO, infringement analysis)	Legal advice; requires registered 변리사 signature

About CNIPA.AI: We focus on assisting 변리사 in completing the most time-consuming core work—"technical content drafting"—from 발명신고서 information extraction to claims initial draft generation, specification section writing, 격식체 rule checking, 단락번호 auto-insertion, and 다항인용다항 violation detection. Filing documents containing inventor PII (such as 주민등록번호) are processed within the 변리사's own systems and never enter the CNIPA.AI platform.

8. Conclusion

A Korean 변리사's work is about finding the optimal path between KIPO's rigorous format requirements (격식체, 단락번호, 한자병기), unique institutional designs (분리출원, 11-category 우선심사, PCT 31-month deadline, 외국어서면출원), and a deep understanding of the technical subject matter.

The April 2022 다항인용다항 prohibition, the February 2025 expansion of 우선심사 to 11 categories, and the 2025 amendment adding "export" acts to the scope of 특허권 효력—all are practice updates that international IP firms must track in real time.

The Claims First drafting philosophy applies equally in Korea. Precise execution of 격식체 and correct 단락번호 injection are baseline quality requirements. Fully leveraging AI assistance on those automatable, rule-based tasks is a realistic path to efficiency gains for every 변리사—while legal judgment and PII handling must always remain within the 변리사's own control.
