Owner review 25, lane A: the 마주 and 두루 families (2026-10-14)

Status: Draft · Date: 2026-10-14 · Clearance of 마주, 두루 and their variants against the Dabusi / 다붓이 alternatives question. Not legal advice; a 변리사 must run the phonetic (칭호) search before any filing.

Owner, review 25 (verbatim). "Can also look into 마주, 두루, 어울 and their variants?" This lane covers 마주 and 두루. 어울 is another lane.

0. Verdicts

Word	Latin	Verdict	Why, in one line
마주 (face to face)	Maju	Blocked	Identical 마주 pending in KR classes 9, 42, 45 and 43; registered in 36 and 38; MAJU pending in US class 35; Maju Digital (DE, 9 and 35). Confirms review 19.
마주 (long-u spelling)	Majoo	Blocked	MAJOO filed in KR class 45 (same filer as 마주 class 45); Majoo is an established Indonesian POS software brand with an App Store app; majoo.com, .co, .kr taken.
마주침 (an encounter)	Majuchim	Risky	Identity-clear everywhere (KIPRIS 1 live row, a clinic; US 0; TMview 0; no app; every domain free), but it is a derivative of the blocked 마주 stem, reads as 마주 + 침 (saliva, acupuncture), and the 마주치다 sense includes "bump into". The 변리사 sound test against 마주 is the risk.
마주봄 (looking at each other)	Majubom	Risky	Registered 마주봄 in class 41 (주식회사 한평원, education and publishing) plus six more live in class 44; majubom.com, .kr, .co.kr taken; @majubom taken on YouTube.
마주해 (face it)	Majuhae	Risky	Clear on every register and every domain, but a bare verb form: weak as a name, ae breaks the vowel rule, and it still begins with the blocked 마주 stem.
두루 (all around, everyone)	Duru	Blocked	Identical 두루 (Duru) registered to 주식회사 두루두루 in classes 35, 36 and 41; 두루 registered in class 9 (비보존제약) and pending in class 9 (아즈모); duru.com, .app, .io, .kr, .co.kr taken; an app named 두루 커뮤니티 club exists in US and KR.
두루두루	Duruduru	Blocked	The same company owns 두루두루 and DURUDURU registered in classes 35, 36, 41, 42 and 45: every class we need but 9 and 38.
두루미 (a crane)	Durumi	Blocked	Identical 두루미 registered in class 42 (two holders), class 35 (a food seller), and 6/16/40/41; CJ Foodville holds 두루미분식 / DURUMI BUNSIK in class 9 (an ordering app) and 35, in the US as well; durumi.com, .io, .co, .kr and .co.kr all taken. Also a mascot noun.
두루 (variant spelling)	Doru	Risky	Koreans read Doru as 도루, "a stolen base" in baseball; US registrations (Doru Squad, class 41) and a Doru Pilates app; doru.com, .app, .io, .co, .kr taken.

Best usable word: none. No word in either family is Clear, and no word is Usable with conditions. The nearest are 마주침 and 마주해, which carry no identical live mark but sit on the blocked 마주 stem. Neither beats 다붓이, whose KIPRIS identity search is empty.

1. Method

All lookups ran 2026-10-14 from this sandbox with curl. Each service was paced at least 8 s apart, and no service refused except TikTok (section 5).

Check	How (re-runnable)
Meaning	ko.wiktionary action=query&prop=extracts&explaintext=1&titles=<word> (it reproduces the 표준국어대사전 senses). 표준국어대사전 and 우리말샘 themselves were not reachable without an API key. The Naver dictionary API refused with HTTP 400. Foreign meanings below come from the TMview and iTunes rows plus my own knowledge and are marked where unverified.
KIPRIS	GET https://www.kipris.or.kr/khome/search/searchResult.do?tab=trademark (cookie jar), then POST https://www.kipris.or.kr/kdtj/grrt1000a.do?method=searchTM with queryText=<hangul>&expression=<hangul>&sortField=RANK&sortState=Desc&currentPage=<n>&numPerPage=30. 6 s between pages. Paging stopped when a full page had no title containing the word. Live = 출원, 공고, 등록.
USPTO	POST https://tmsearch.uspto.gov/prod-stage-v1-0-0/tmsearch, body {"query":{"bool":{"must":[{"match":{"wordmark":{"query":"<latin>"}}}],"filter":[{"term":{"alive":true}}]}},"size":100}. Returns only marks containing the word.
TMview	POST https://www.tmdn.org/tmview/api/search/results, browser User-Agent, Origin and Referer, "fNiceClass":["9","35","36","38","41","42","45"], "fTMStatus":["Registered","Filed"]. Worked on every call. Fuzzy on the Latin spelling.
iTunes	https://itunes.apple.com/search?term=<name>&country=us|kr&entity=software&limit=30, rows whose app name or seller contains the term. Google Play was not readable.
Domains .com, .app	https://rdap.org/domain/<name>.<tld>: 200 registered, 404 free. get<name>.com the same way.
Domains .io, .co, .kr, .co.kr	whois on port 43 (printf '<domain>\r\n' | nc whois.nic.io 43; whois.registry.co; whois.kr). The rdap.org 404s for .io and .co were wrong (they answered 404 for registered names), so these four come from whois only. rdap.kisa.or.kr answered 404 for everything and was discarded.
Handles	YouTube curl -A <browser UA> https://www.youtube.com/@<handle> (404 free, 200 taken). TikTok oembed https://www.tiktok.com/oembed?url=https://www.tiktok.com/@<handle>. The statusCode endpoint returned an empty body.

Classes checked: 9, 35, 36, 38, 41, 42, 45. A 변리사 must run the sound-alike search; KIPRIS and USPTO here match the spelling, TMview matches fuzzily.

2. 마주 and Majoo

Meaning (ko.wiktionary, which follows 표준국어대사전).

• Adverb 마주: "서로 똑바로 향하여" (face to face). Derives from Middle Korean 마조 (석보상절, 1447). Related verbs: 마주치다, 마주하다.
• Noun 馬主: a racehorse owner (the sense used by 한국마사회).
• 마주앙 (Majuang) is a household wine brand of 롯데칠성음료, with about 20 live marks, so Koreans hear "wine" in the neighbourhood of 마주.
• Malay and Indonesian maju means "forward, advanced"; Indonesian Majoo is a company name (POS software). Positive, but it ties the Latin to Indonesian businesses.
• Flagged in review 12: one letter from Maru, the owner's health app.

KIPRIS 마주. 7,157 rows; the first 630 (21 pages, ranked) were read, covering every exact title and compound the ranker surfaced. Nine live exact 마주 marks:

Mark	Status	Class	Holder	App no.
마주	공고	45	주식회사 씨피랩스	4020250095536
마주 (M)	출원	9	주식회사 스토어바	4020250103884
마주	출원	42	정혜린	4020260058162
마주	출원	43	정혜린	4020260058172

Compounds led by 마주 in our classes: 마주톡 (class 9, pending, AAC software), 마주친구 (9 and 42, pending, filed 2026-09-16), 마주앤드 (MAJU&, 9 and 38, pending), 마주:온 (30 and 35), 마주온 (41 and 42, 충청남도 교육감, registered), 마주로 / 마주쉼 / 마주옴 / 마주선 (class 45, pending, a cooperative's elder-care family), 마주이야기 and 마주스토리 (35 and 41), 마음마주 (41 and 44), 마주함 (41 registered, 45 pending). Class 41 and 45 are not clear either: the stem is crowded in every one of our classes.

TMview, Latin maju. 441 rows. Relevant: 마주 KR class 45 filed (씨피랩스); maju KR 41/44 registered (주식회사 마주심리상담소); 마주 KR 42 filed; MAJU KR 36 registered; MAJU US class 35 filed (Juan David Florian Moreno); maju DE classes 9 and 35 registered (Maju Digital GmbH & Co. KG); MAJU DIET CONCEPT in FR, WO (classes 9 and others). The remaining rows are Brazilian (Maju is a Brazilian nickname for Maria Julia, dozens of class 35 and 41 marks).

USPTO maju. 9 live. In our classes: MAJU class 35 (new application) and MAJU classes 9, 18, 21, 29, 30, 44 (MAJU DIET CONCEPT, new application). The rest are MAJU SUPERFOODS class 5 and a Malaysian restaurant class 43.

Majoo. USPTO: MAJOO registered, class 3 (an Inibiza skincare mark). TMview: MAJOO KR class 45 filed by 주식회사 씨피랩스, the same filer as the 마주 class 45 mark. Plus near rows (Majool, Majoon, MAMAJOO).

Nothing is a tennis or club app, but there are several exact-name apps in Finance and Health.

Domains. maju.com, maju.app taken; maju.io taken (Spaceship, expires 2026-12-03); maju.co taken (to 2027-03-07); maju.kr taken (ciel korea); maju.co.kr taken (Webbank); getmaju.com free. majoo.com, .co, .kr, getmajoo.com taken; majoo.app, .io, .co.kr free.

Handles. @maju and @majuapp free on YouTube; @majoo and @majooapp taken on YouTube. TikTok unreadable (section 5).

Verdict: Blocked (Maju and Majoo). Reasons: five identical pending or registered 마주 marks across classes 9, 36, 38, 42, 43 and 45, a pending identical MAJU in the US class 35, a registered Maju Digital in Germany classes 9 and 35, and the Majoo software company.

3. The other 마주 forms

마주침 / Majuchim

• Meaning. The nominal form of 마주치다 ("to meet by chance, to bump into", also "to clash"). ko.wiktionary has no 마주침 page, so I could not confirm it as a dictionary headword; treat it as a derived noun. Read as 마주+침, 침 is also "saliva" and "acupuncture needle".
• KIPRIS. 24 rows, all read. One live row containing it: 마주침한의원 (registered, class 44, 김희진, KR4020220084452). No other 마주침 title.
• TMview, USPTO, stores. TMview 0; USPTO 0; iTunes 0 in US and KR (Latin and Hangul).
• Domains. majuchim.com, .app, .io, .co, .kr, .co.kr and getmajuchim.com are all free. This is the only word in the lane with a fully free domain set.
• Handles. @majuchim and @majuchimapp free on YouTube.
• Verdict: Risky. Identity clear, but KIPO compares by sound and the first two syllables are the 마주 that is pending in classes 9, 42, 45 and registered in 36 and 38. Three syllables, an -chim ending that is awkward in English, and the "bump into" sense weaken it further.

마주봄 / Majubom

• Meaning. 마주 + 봄 ("looking face to face"); also "spring" in Korean (봄), which makes it a spring pun in Korean. Not a dictionary entry on its own.
• KIPRIS. 150 rows, 60 read (paging stopped after two pages without further title hits). Ten live marks contain it. Identical 마주봄: class 41 registered (주식회사 한평원, KR4020190022067: textbook publishing, online publishing, 교육업, 통신강좌); class 44 registered by 조가람 (KR4020210075257), 김민주 (KR4120160026667), 박준범 (KR4020240048825, dental) and pending by 전용우 (KR4020250237029, home nursing); class 44 published by 최경범. Compounds: 마주봄펫 (41, 35, 44), 마주봄한의원 (44).
• TMview. 마주봄 KR class 41 registered (한평원). USPTO 0. iTunes 0.
• Domains. majubom.com, .kr (Whois Domain Admin) and .co.kr (LEEINSUNG) are taken; .app, .io, .co and getmajubom.com are free.
• Handles. @majubom taken on YouTube (200), @majubomapp free.
• Verdict: Risky. An identical registered mark sits in class 41, a class we need. Its goods are education and publishing, so conflict is arguable but not safe.

마주해 / Majuhae

• Meaning. Informal "-해" form of 마주하다 ("to face, to confront"). A verb ending, not a noun.
• KIPRIS. 4 rows, 0 live containing it.
• TMview 0, USPTO 0. iTunes: Hangul KR 1 unrelated result (Adobe Firefly); Latin US 16 results, none named Majuhae; KR 0.
• Domains. majuhae.com, .app, .io, .co, .kr, .co.kr and getmajuhae.com all free.
• Verdict: Risky. Clear on the registers, but it shares the 마주 stem, the ae breaks the vowel rule, and a verb ending reads as a sentence, not a name.

4. 두루 and its variants

Meaning (ko.wiktionary).

• Adverb 두루: "일반적으로 널리" (broadly, all around, without omission), as in 두루 능통하다. Related: 두루두루, 골고루, 널리.
• 두루미: the crane (두루미과, the bird); also a long-necked jug (두루미병).
• Neighbouring words Koreans hear: 두루마리 (a roll, toilet-paper roll), 두루마기 (a coat), 두루치기 (a stir-fry dish; the food collision is live in the registry, below).
• 두루누리: the government's social-insurance support for small firms; 두루누비: the 한국관광공사 walking-trail brand (registered, class 41; an app with 170 ratings in KR).
• Turkish duru means "clear, pure" and is a common Turkish given name (from review 12; positive but a Turkish word). The soap brand DURU (Evyap, Turkey) is registered in many classes. Romanian Doru is a common male name. These are my knowledge and the TMview owners, not a dictionary read.
• Rhymes with Maru (review 12 mark-down).

KIPRIS 두루. 1,594 rows; 810 (27 pages) read; 266 live marks contain the string, mostly 두루치기 food and 두루마리 compounds. Exact 두루 live: 13 marks, in classes 7, 9, 12, 16, 20, 35, 36, 39, 40 and 41. In our classes:

KIPRIS 두루두루. 148 rows, all read. Live: 두루두루 and DURUDURU registered by 주식회사 두루두루 in classes 35, 36, 41, 42, 45 (ten registrations: 4020190057580 / 81 / 82 / 84, 4120150034195 / 96 / 98 / 200, 4119990000713, 5120100000476). Classes 9 and 38 are not held.

KIPRIS 두루미. 126 rows, all read. Live exact 두루미: class 42 (김완겸, KR4520010003938; 박의준, KR4020180091321 in 42 and 45), class 35 (안은솔, KR4020240025524), classes 6/16/40/41 (주식회사 레즐러, KR4020180087363).

Verdicts.

• 두루 / Duru: Blocked. Identical registered 두루 (Duru) in class 41, 35 and 36 (one company), two class 9 marks, a same-category app, no free common domain for the .com/.app/.io set, Turkish brand heft (DURU soap, DURU bulgur) in many registers.
• 두루두루 / Duruduru: Blocked. The same company registered the exact word in five of our seven classes.
• 두루미 / Durumi: Blocked. Identical registered 두루미 in class 42 twice; CJ Foodville holds a class 9 ordering-app mark; domain set taken; the crane is a mascot noun, which the review 16 brief excludes.
• Doru: Risky, not recommended. The Latin spelling is read 도루 ("stolen base") by Koreans, which also means the brand pronounces as a baseball word. US Doru Squad (class 41) and a Doru Pilates app also exist. It does not escape the 두루 conflicts, since KIPO compares by sound and 도루 and 두루 are close.

5. Limits of this lane

• TikTok refused or timed out on every oembed call (429, 503, 504). The statusCode JSON endpoint returned an empty body. TikTok availability is therefore unknown for every handle. YouTube is the only handle result.
• YouTube HTTP 200 means a page exists, which can be a channel or a redirect to a generic page; I did not read bodies.
• 표준국어대사전 and 우리말샘 were not queried directly; the senses come from ko.wiktionary. 마주침 could not be confirmed as a headword.
• KIPRIS depth. 마주 (7,157 rows) was read to row 630, 두루 (1,594) to row 810, 마주봄 (150) to row 60, because the ranker lists exact titles first and paging stopped when a full page held no title with the word. 두루두루, 두루미, 마주침 and 마주해 were read in full. For 마주 and 두루 the live-exact list is a floor.
• Google Play, Naver, Instagram and other handles were not checked.
• Sound-alikes (칭호). Not tested beyond TMview's fuzzy Latin. 마주/마준, 두루/도루/뚜루 and similar need the 변리사.

Usable

None. Every word in the 마주 and 두루 families is Blocked or Risky.

Nearest, for completeness (not recommended): 마주침 / Majuchim and 마주해 / Majuhae, identity-clear with all domains free but built on the blocked 마주 stem.
