If you run a global business, protecting one mark across Korea, the US, Japan, and China is a recurring task. The four economies are big enough — and the counterfeiting risk in some of them high enough — that they tend to travel together in any portfolio. Yet filing, examination, opposition, and renewal procedures differ in important details. This article puts the headline numbers from USPTO, JPO, CNIPA, and Korea's KIPO into one table and walks through what foreign applicants need to know.
Side-by-side numbers
| Item | Korea (KIPO) | US (USPTO) | Japan (JPO) | China (CNIPA) |
|---|---|---|---|---|
| File-to-register avg. | 10-14 months | ~11.7 months | 7-9 months | 12-18 months |
| Expedited | Yes (~2 months) | No formal scheme | Optional accelerated | No formal scheme |
| Opposition window | 2 months from gazette | 30 days post-publication (extendable) | 2 months from registration gazette | 3 months from gazette |
| Renewal window | 12 months before-to-deadline | §8 at 5-6, §8+§9 at 9-10, then 10y | 6 months before-to-deadline | 12 months before-to-deadline |
| Use requirement | 3-yr non-use cancellation | §8 declarations of use mandatory | 3-yr non-use cancellation | 3-yr non-use cancellation |
| Foreign-applicant rep | Required | Required (US-licensed atty) | Required | Required |
| Term | 10 years (renewable) | 10 years (renewable) | 10 years (renewable) | 10 years (renewable) |
Korea (KIPO)
10-14 months from filing to registration on average. With the right grounds (use, intent-to-use, third-party warning), expedited examination compresses the path to about two months. Opposition window is two months from gazette. Renewal opens 12 months before the deadline; a six-month grace period after expiry allows late renewal with a surcharge, and the right lapses thereafter. Of the four jurisdictions, Korea has the most developed expedited path.
US (USPTO)
Per the USPTO Trademarks Dashboard, FY2025 figures show ~5.6 months to first action and ~11.7 months end-to-end. The US is a use-based system: 1A applications (already in use) differ from 1B (intent-to-use), and 1B requires a Statement of Use before registration. Maintenance also differs sharply — a §8 use declaration at 5-6 years, §8+§9 at 9-10 years, then 10-year cycles. Missing a declaration is fatal.
Japan (JPO)
JPO is the fastest of the four: ~6-7 months to first office action and ~7-9 months to registration. Opposition runs two months from registration gazette. Foreign-resident applicants get a standard three-month OA response window plus 1+2 months of paid extensions. Foreign residents cannot file directly with the JPO — a Japanese attorney is mandatory.
China (CNIPA)
Filing-to-registration runs 12-18 months. The opposition window is the longest at three months from publication, so post-filing certainty arrives later. From 2024, CNIPA tightened examination quality and registrations fell about 29% versus 2023, while opposition and invalidation case loads grew. Renewal opens 12 months before expiry, with a six-month grace period at additional fee.
Strategy for foreign applicants
All four jurisdictions require local representation. The lowest-friction way to manage four countries is the Madrid Protocol — Korea, the US, Japan, and China are all members, so a single international application can extend to all four, and follow-on changes (renewal, ownership, address) can be done centrally. Local agents are still needed for office actions and oppositions.
Where to start depends on market priority, existing rights, and budget. If Korea hosts your headquarters or production and you need all four, a Korean base + Madrid is efficient. If the US is the #1 market, a direct US filing may be quicker. China should be filed early regardless of market entry timing, because of squat-registration risk.

Frequently asked questions
Madrid or direct national filings?
Madrid wins when several countries are needed at once or follow-on management matters (renewal, ownership transfer, address change). It is also typically cheaper across multiple countries. Direct filings can win when a single country is the only target or local refusals are a likely fight. For China, even via Madrid, you still want a separate Chinese-character filing for full coverage.
Are the rights identical once granted across all four?
Each right is independent and is interpreted under that country's law. The US emphasizes use, Japan and Korea center on registered goods/services, China leans on the registered visual mark. Run infringement analyses country by country — a registration in one country does not auto-define rights in another.
Can I manage all renewals from one calendar?
Renewal mechanics differ enough that you need different reminders and document checklists. The US adds §8 use declarations; Japan and China start their windows 6-12 months out. IP-management platforms — iphere among them — keep all four jurisdictions on one calendar and reduce miss risk substantially when you operate across all four.
