Our patent and utility model practice covers prior art analysis, application drafting and prosecution in Korea, with overseas filings coordinated through local counsel.
SCOPE & APPROACH
Scope of work
From invention review and drafting to examination and registration, we handle patent and utility model matters in Korea. We coordinate overseas filings with local counsel, taking account of your disclosure timetable and market plans.
01
Invention analysis & prior art
We compare the invention with the prior art, assess the evidence for its technical contribution and identify the scope of protection to pursue.
02
Drafting & prosecution
We prepare specifications and claims, analyze office actions and develop responses and amendments informed by the prosecution history.
03
Korean filings & overseas coordination
We align patent and utility model filings with development milestones, planned disclosures and target markets, working with local counsel on overseas procedures.
Prepare for your consultation
A technical summary, drawings, prior art, existing filings and any disclosure or launch deadlines will help us assess the matter.

01
Patents: protecting technical inventions
Patents protect technical inventions relating to products or processes. Novelty, inventive step and adequate disclosure matter; the claims define the protection sought. Rights arise on registration and generally last 20 years from filing. Prior art and the planned disclosure or launch should inform the filing strategy.
Utility models cover devices involving the shape, structure or combination of articles, rather than methods themselves. Registration follows examination; the term is generally 10 years from filing. Compare the technical features, commercial life and required scope when choosing between a patent and a utility model.
Prepare the application, description, claims and necessary drawings, and check the applicant, inventors and priority details. For current Korean patent and utility model applications, examination generally must be requested within three years of filing. Respond to office actions through arguments and permitted amendments, then manage renewal fees and legal status after registration.
Accelerated examination and divisional applications
Accelerated examination changes the examination order for eligible applications supported by evidence; it does not relax patentability requirements. A divisional application separates subject matter within the original disclosure for independent examination. Assess the procedural stage, permitted filing period, added-matter limits and costs.
