Under Armour

The Japan Patent Office (JPO) dismissed the opposition filed by Under Armour, Inc. against TM Reg no. 6839569 for the stylized mark “ARMOURIN” in Classes 25 and 28 due to dissimilarity to and unlikelihood of confusion with earlier registrations for the mark “UNDER ARMOUR”.
[Opposition case no. 2024-900229, decided on July 2, 2025]

ARMOURIN

The contested mark (see below) was filed by AMH LO INC., a U.S. company, in connection with apparel and footwear, including golf shoes, in Class 25; and sporting articles, inter alia golf clubs, golf equipment, in Class 28, with the JPO on December 26, 2023 [TM App no. 2023-143646].

The JPO examiner, as a result of substantive examination, granted protection of the mark on August 6, 2024 without issuing an office action.

After registration, the mark was published in the gazette for a post-grant opposition on September 9, 2024.

Opposition by Under Armour

Under Armour, Inc., a U.S. sports apparel company, filed an opposition against the mark “ARMOURIN” with the JPO on November 8, 2024, and claimed cancellation based on Article 4(1)(xi) and (xv) of the Japan Trademark Law due to the similarity to and likelihood of confusion with their earlier registrations for the word mark “UNDER ARMOUR”.

Under Armour argued the contested mark contains the term “ARMOUR” that has become famous among relevant consumers of the goods in question and played a prominent role in identifying a commercial source of the goods bearing the cited mark. Therefore, the contested mark should be considered similar to the cited mark “UNDER ARMOUR” and likely to cause confusion with the opposer’s business when used on the goods in question.

The JPO decision

Article 4(1)(xi) – Similarity of mark

The JPO Opposition Board found that the contested mark does not give rise to any specific meaning as a whole.

Regarding the cited mark “UNDER ARMOUR”, the Board observed that there is reason to dissect the term “UNDER” and “ARMOUR” into individual parts from visual and conceptual points of view.

Global assessment suggests there is no similarity in appearance and sound. Besides, a conceptual comparison is neutral as neither the contested mark nor the cited mark has a clear meaning. Therefore, the marks are dissimilar, even if the goods in question are the same as those cited, by taking account of the overall impression, memory, and association created in the minds of relevant consumers.

Article 4(1)(xv) – Likelihood of confusion

The Board negated a famousness of the cited mark “UNDER ARMOUR” because the opposer failed to provide sufficient objective evidence of actual sales amount and advertising in Japan.

Bearing in mind that the contested mark has a low degree of similarity to the cited mark, there is no reason to believe that relevant consumers will confuse the source of the goods in question bearing the contested mark with Under Armour, the Board noted.

In the light of the foregoing, the Board dismissed the opposition and declared the contested mark valid as status quo.

The Opposition Board of the Japan Patent Office (JPO) dismissed an opposition filed by Under Armour Incorporated, an American sporting goods manufacturer which supplies athletic and casual apparel, as well as footwear, against trademark registration no. 5924494 for the “H” device mark designating apparels, footwear, headgear, gloves, cycling wears in class 25.

Under Armour logo

In an opposition, Under Armour claimed trademark registration no. 5924494 violates Article 4(1)(x), (xi), (xv) and (xix) of the Japan Trademark Law by citing a senior trademark registration no. 4701254 for the Under Armour logo (see below in left). Cited registration has been effectively registered since 2003 by designating clothing, footwear, sportswear, sports shoes in class 25.

Opposed mark

Opposed mark was applied for trademark registration on August 26, 2016 in the name of AGEAS INC. (USA) covering various goods in class 25 (see above in right).

Without any refusal notice from the JPO, opposed mark was granted for registration on January 16, 2017, and published in gazette for opposition on March 21, 2017.

Subsequently, Under Armour filed an opposition in May.

Opposition grounds

Article 4(1)(x) prohibits to register a trademark which is identical with, or similar to, other entity’s well-known mark over goods or services closely related with the entity’s business.
Article 4(1)(xi) is a provision to refrain from registering a junior mark which is deemed identical with, or similar to, any senior registered mark.
Article 4(1)(xv) prohibits to register a trademark which is likely to cause confusion with a business of other entity.
Article 4(1)(xix) prohibits to register a trademark which is identical with, or similar to, other entity’s famous mark, if such trademark is aimed for unfair purposes, e.g. gaining unfair profits, or causing damage to the entity.

To sum up, Under Armour wins if the Under Armour logo is considered confusingly similar to opposed mark. Meanwhile, even if the Under Amour logo obtains a high degree of popularity and reputation among relevant public in Japan, the opposition is overruled as long as both marks are dissimilar and unlikely to cause confusion.

Board decision

The Opposition Board admitted a high degree of popularity and reputation of the Under Armour logo as a source indicator of opponent among relevant consumers in the fields of sports.

In the assessment of mark appearance, the Board concluded:

“It is apparent that respective mark gives rise to a diverse visual impression in the mind of consumers because of different configuration. Opposed mark can be perceived as a device deriving from ‘H’. In the meantime, the cited mark as a device consisting of ‘U’ and upside-down ’U’. Besides, from phonetical and conceptual points of view, there exists no element to find similarity of the marks. Based on the foregoing, both marks shall be less likely to cause confusion due to a remarkable degree of visual difference.”

As a conclusion, the Board decided opposed mark is not subject to Article 4(1)(x), (xi), (xv) and (xix) of the Trademark Law, and admitted to continue a status quo.
