Owner review 13 — rulings (2026-10-13)

Status: Active · Date: 2026-10-13 · Answers the owner's ask: can we actually use Madang, Duri, Dodam or Oreum? Evidence:

• stores, brands and meaning;
• domains and handles;
• trademarks.

Companion: review-12 rulings.

This is a knock-out search: it finds what blocks a name today. It is not a legal clearance opinion.

Verdicts

The classes searched are 9 (apps), 35 (club and membership administration), 41 (sports and club services) and 42 (software as a service).

Name	Trademarks	Stores and brands	Domains and handles	Verdict
Madang (마당)	No identical live mark in our classes in Korea, the US or the EU. 마당 lives only inside compounds (상상마당, 마당발, 한마당).	No app named Madang in the US, Korean or Japanese App Store. Hangul 마당 has one app with no ratings. Search results are crowded by Papua New Guinea.	.com parked since 1998 (price unread); .app is a live Korean community site; getmadang.com, madang.club and madang.tennis are free; @madangapp is free on X, YouTube, TikTok and Naver Blog.	Usable with conditions
Oreum (오름)	A 2025 OREUM filing (KR402025000033061, 066, 079) covers classes 9, 35 and 41. A 2026 OREUM filing and a registered 오름 cover class 35. In Korea the first to file wins.	The Oreum Network app holds the exact name in both stores (since 2026-06).	oreum.app is a live Jeju hiking-log app.	Blocked in Korea, unless the earlier filing is bought or lapses
Dodam (도담)	A pending DoDam filing (KR402025000234388, 2025) covers classes 9 and 42. A registered Dodam/도담 covers class 35. The US is clear.	Hangul 도담 apps are mostly for parenting.	The best domains: dodam.app and dodam.io are free.	Blocked in Korea for apps and software
Duri (두리)	Live DOORI and 두리 marks in classes 9, 35 and 42. Respelling does not help, because Korea compares marks by sound.	Six Latin Duri apps, two Doori apps and seven Hangul 두리 apps; the 두리요 nightlife app; 차두리 the footballer.	duri.com is a cosmetics store.	Risky

Respellings do not escape. Orum is blocked by Orum, the US sales-software company (orum.com, ORUM marks). Oroom has an EU class-41 mark and reads as "or room".

Madang: the conditions

1. Distinctiveness. A 변리사 should give an opinion on 마당 alone. As a word for a gathering or forum (토론마당, 놀이마당), Korea's examiners could call it weak for event and information services (class 41, parts of 35). The many registered 마당 compounds show it is accepted as part of a mark; they do not show it is accepted alone. If it is weak, a stylised logo mark or a compound reading is the usual remedy.
2. Read three Korean class-35 marks. E madang / 09 maDanG (봉성춘), OT MADANG (디엔디) and AROUND MADANG (어라운드): their goods lists were not read.
3. The web address.
   • Price madang.com at the parking page.
   • Otherwise use getmadang.com, with madang.club or madang.tennis as the short link.
   • Register @madangapp on the handle sites.
4. The two brands. Madang and Maru Health will read as siblings, since both name parts of a Korean house. That is a plus if you want one family and a cost if not.

What we could not check

• Google Play: its search page returns 0–1 results to a script, so the absences there prove nothing.
• WIPO's database and the Japan Patent Office: not reached.
• Instagram and Threads handles: not readable.
• Fees: the asking prices of parked domains, and a 변리사's search fee.
• Re-runs: my own re-run of the Korean and EU database searches was refused after the lane's queries. The blocking filings above carry their application numbers, so they can be confirmed in KIPRIS by number in minutes.

Costs to plan:

• KIPO electronic filing is about 52,000 KRW per class; sources conflict between 46,000 and 62,000.
• A Madrid filing costs a 653 CHF base fee, plus 460 CHF per class for the US and about 221 CHF for Japan.
• A US direct filing is 350 USD per class.

Open for you

1. Take Madang to a 변리사 for the distinctiveness opinion and a full clearance (I recommend it). Or have the attorney read the OREUM, DoDam and DOORI goods lists first, before dropping the other three.
2. The web address: price madang.com, or settle on getmadang.com?
3. Madang beside Maru Health: one family, or should one of the two change?
