Korean Patent System vs. US and European Patent Systems
This article compares key differences between the Korean, US, and European patent systems, covering topics such as grace periods, novelty standards, patentable subject matter, examination procedures, and opposition systems, highlighting how each jurisdiction's unique rules affect patent strategy for applicants.
Background
- South Korea has one of the world's busiest patent offices (KIPO) and is a major player in high-tech industries (semiconductors, displays, batteries, telecoms). Understanding how its patent system differs from the US (USPTO) and European (EPO) systems matters for global companies filing there.
- Key differences covered: Korea runs a "first-to-file" system (like Europe but unlike the US pre-2013), has faster examination timelines, publishes applications earlier (18 months from filing, like Europe), and treats utility models (a second-tier protection for incremental inventions) more actively than the US or Europe.
- Korea's patent office also conducts expedited examination (for commercial use or startup applicants) and has a unique "3-track" system allowing applicants to choose examination speed. Post-grant opposition procedures also differ from the US and Europe.
