Fast-Track Patent Examination in Korea: Granted in Months, Not Years

Korea is quietly one of the fastest major jurisdictions in which to get a patent granted — provided you use the expedited-examination system. This guide covers the current numbers, the government's 2026 acceleration drive, and — most usefully — the expedited-examination grounds that foreign applicants can actually qualify for.

2026: Korea's IP administration is racing to cut examination time

In its mid-2026 policy briefing, Korea's IP administration (MOIP — the Ministry-level successor to KIPO) announced a package of measures under the banner "changing the game of economic growth with IP." The parts that matter to filers:

• Examination backlog target: 14 months for patents (11.2 months for trademarks) by the end of 2026, through additional examiners and full-scale deployment of AI examination tools.
• Ultra-fast examination expanded for nationally important fields — first results within 1 month.
• Supporting ecosystem moves: overseas-patent support for 50 selected technologies, a ₩140bn IP monetization/transaction fund, IP finance expanded toward ₩13.3tn, an integrated IP search service covering patents/trademarks/copyright, and a substantially enlarged "technology police" unit (4 divisions / 61 investigators) focused on technology-leakage and trade-secret enforcement — a signal of how seriously Korea now polices IP.

Context for budgeting: on the normal route, examination currently begins on average about 18 months after the examination request (improving toward the 14-month target). The expedited route changes that picture completely.

Expedited (priority) examination: the numbers

Per KIPO statistics (Dec 2023), expedited cases averaged about 6 months from filing to registration. In our own practice, a well-prepared expedited case can be granted roughly 4–5 months from the Korean filing date — a speed few major offices can match, and a genuine strategic weapon when you need an enforceable Korean right quickly (e.g., an infringer or a licensing negotiation).

Grounds foreign applicants can actually use

Many of the two dozen statutory grounds are tied to Korean government programs, but several are fully open to foreign applicants:

• ① "Working the invention" (or preparing to) — the most broadly usable ground. If the applicant is commercially practicing the invention, or concretely preparing to (manufacturing, sales, licensing into Korea), the application qualifies. The catch: you must file an evidence package (statement of working with supporting documentation) that satisfies the examiner — and what counts as sufficient is a matter of practical experience. This is an E-BIRD specialty: we prepare the working-statement and supporting materials for you, and we have a long track record of these being accepted. Result: examination typically taken up 2–3 months after the request, with grant possible in about 4–5 months from filing in fast cases.
• ② Fourth-industrial-revolution technology fields — applications classified in designated tech classes covering AI, IoT, 3D printing, autonomous vehicles, big data, cloud computing, intelligent robotics, smart city, VR/AR, innovative pharmaceuticals, renewable energy, personalized healthcare, drones, next-generation communications, intelligent semiconductors, advanced materials, blockchain, smart manufacturing and next-generation biopharmaceuticals. If your invention sits in these fields (most of our inbound work does), expedited examination is available essentially as of right.
• ③ PPH and office-to-office arrangements — where Korea has an agreement with your home office (US, JP, CN, EP and many others) and the earliest dates align, work-sharing-based expedited examination is available, typically leveraging your existing allowance or search results. See our PPH guide for the requirements and documents.
• ④ PCT cases where KIPO acted as ISA — international applications searched by the Korean office qualify directly.
• ⑤ Other targeted grounds — carbon-neutral/green technology, pollution-prevention technology, semiconductors and national strategic technologies (per periodic notices), and third-party infringement of a published application.

What it costs and how we handle it

Two cost components, both fixed and published like everything else we do:

The band reflects the work involved: a classification-based request (e.g., a fourth-industrial-revolution technology field) sits at the lower end, while a "working the invention" evidence package — statement of working plus supporting documentation, prepared to examiner-accepted standard — sits at the upper end. When you engage us, your attorney's first comment (within 24 hours) includes a free assessment of which expedited ground your case can use and what evidence it would take, so you decide with the exact figure in front of you.
