Foreign businesses and independent creators — YouTubers, designers, app developers, brands expanding into the Korean market — routinely make the same mistake: assuming that intellectual property rights established abroad automatically travel with them into Korea. Copyright largely does, thanks to international treaties. Trademark rights almost never do, and that gap catches out a striking number of foreign businesses right when they're gaining traction here.
→Copyright (저작권): Protected the Moment You Create It
Korea is a member of the Berne Convention and the WTO's TRIPS framework, so copyright protection (저작권, jeojakgwon) under the Copyright Act (저작권법, jeojakgwonbeop) generally exists automatically the moment a work is created — no registration required, whether you're Korean or foreign, and whether the work was created in Korea or abroad. If someone in Korea copies your software, translates your book without permission, reposts your video content, or rips off your original artwork, you generally have a copyright claim without needing to have registered anything first.
Registration with the Korea Copyright Commission (한국저작권위원회) is optional but useful — it creates a public record of your authorship and creation date, which becomes valuable evidence if ownership is later disputed, and it's a prerequisite for pursuing certain enhanced statutory damages in litigation.
→Trademark (상표권): First-to-File, Not First-to-Use
This is where foreign businesses get blindsided. Under the Trademark Act (상표법, sangpyobeop), Korea follows a first-to-file system — the legal right to a trademark (상표권, sangpyogwon) generally belongs to whoever registers it with the Korean Intellectual Property Office (특허청, KIPO) first, largely regardless of who used the mark first anywhere else in the world.
- A local party can legally register your brand name, logo, or product name in Korea before you do — sometimes deliberately, anticipating your market entry (a practice known as trademark squatting)
- Once registered, that party can block your own use of your own brand name in Korea, demand licensing fees, or sue you for infringing "their" mark
- Prior use abroad is not automatically a defense — Korean courts have recognized limited exceptions for marks that are already famous/well-known in Korea specifically, but that's a high bar, not a safety net for an ordinary business
In Korea, the trademark generally belongs to whoever files first — not whoever used it first.
→What Infringement Actually Looks Like
| Copyright Infringement (저작권 침해) | Trademark Infringement (상표권 침해) |
|---|---|
| Copying source code, designs, articles, photos, or video without permission | Using a name, logo, or slogan identical or confusingly similar to a registered mark, on related goods/services |
| Unauthorized translation or adaptation of a copyrighted work | Registering a domain name or business name built around someone else's registered mark |
| Reposting or redistributing content without a license | Selling counterfeit or knockoff goods bearing a registered mark |
→Enforcement Options if You've Been Infringed
- Cease-and-desist letter (내용증명, naeyongjeungmyeong) — often the first, fastest step, and frequently enough to resolve smaller cases without litigation
- Civil suit for damages and injunction — filed in the relevant district court, seeking both compensation and an order stopping continued infringement
- Criminal complaint — both copyright and trademark infringement can be prosecuted criminally in Korea, giving police and prosecutors, not just courts, a role in stopping ongoing infringement
- Customs recordal — registering your trademark with the Korea Customs Service (관세청) allows border seizure of counterfeit imports before they ever reach the market
→If You're the One Accused of Infringement
Foreign businesses also end up on the receiving end — sometimes fairly, sometimes because a competitor or a bad-faith registrant is using a Korean trademark registration as leverage. If you receive a cease-and-desist letter or infringement complaint in Korea, don't assume it's baseless just because you've used the mark for years elsewhere; check what's actually registered in Korea first, since that registration — not your history abroad — is usually what a Korean court will look at.
→What Foreign Businesses Should Do Before — Not After — Entering the Korean Market
- Run a trademark search with KIPO before launch to see whether your brand name, logo, or product name is already registered or pending in Korea
- File your own trademark application early — even before you're fully ready to launch — given how routinely squatters move faster than the actual brand owner
- Register copyright-sensitive work with the Korea Copyright Commission if it's commercially significant, to strengthen your evidentiary position later
- Keep dated records of creation (source files, drafts, timestamps) for any content or software you'd need to prove you authored first
- If you discover a conflicting registration already exists, get a Korean IP attorney to assess whether a cancellation or opposition action is realistic before you invest further in the Korean market
Intellectual property protection in Korea rewards whoever moves first on paper — not whoever built the brand first in reality. For a foreign business, that single structural difference is worth understanding well before a dispute forces you to learn it the hard way.
