Trademark dispute: MINI vs. DMINI

The Japan Patent Office (JPO) dismissed an opposition claimed by BMW against TM Reg no. 6798869 for wordmark “DMINI” in class 12 due to dissimilarity to and unlikelihood of confusion with a famous small car “MINI”.
[Opposition case no. 2024-900137, Gazette issued date: April 25, 2025]


DMINI

Mitsubishi Motors Corporation filed a trademark application for word mark “DMINI” in standard character for use on automobiles, motorcycles, bicycles, electric cars, hybrid electric cars, driverless cars and other goods in class 12 with the JPO on October 10, 2023.

The JPO examiner did not raise any objection in the course of substantive examination, and granted registration on March 29, 2024.

The mark “DMINI” was published on trademark registration gazette (TM Reg no. 6798869) for a post-grant opposition on May 7, 2024.


Opposition by BMW

Bayerische Motoren Werke GmbH (BMW) filed an opposition with the JPO on July 5, 2024 before the lapse of two-month statutory period counting from the publication date.

BMW requested the cancellation of the mark “DMINI” based on Article 4(1)(vii), (xi), and (xv) of the Japan Trademark Law by citing its owned earlier trademark registrations for wordmark “MINI” in class 12.

Allegedly, the cited mark has become famous among the relevant consumers to indicate a source of the world-famous small cars “MINI” that have been imported into Japan for more than the past six decades. BMW argued that the literal element “MINI” would be dominant in the opposed mark, taking into account the high degree of recognition of the cited mark “MINI” among the consumers. If so, both marks should be considered similar, or likely to cause confusion in relation to the goods in question.


JPO decision

From the produced evidence, the JPO Opposition Board found the cited mark “MINI” has acquired a remarkable degree of popularity and reputation among consumers to indicate the automobiles (small cars) manufactured by BMW.

However, the Opposition Board question similarity of the marks by stating that:

There is a difference in the presence or absence of the letter “D” at the beginning of each mark. The difference has a strong visual impact and is likely to create a different impression given the relatively short character structure of five and four letters respectively. Therefore, there is a low degree of visual similarity between the marks.

Secondly, there is a difference between in the overall sound of “DMINI” and “MINI” due to the presence or absence of the sound “D” at the beginning. It has a significant impact on the overall sound, given the short phonetic structure of four or two sounds, and thus the overall tone and aural impression are clearly different to the extent that a risk of confusion in pronunciation is not conceivable.

Thirdly, the opposed mark does not give rise to a specific meaning, whereas the cited mark has a meaning of “famous automobile brand owned by BMW”. If so, there will be any conceptual confusion.

Even if the cited mark “MINI” has become famous and the goods in question are highly related to the goods bearing the cited mark administered by BMW, given the facts that the term “MINI” is not a coined word and the low degree of similarity between “MINI” and “DMINI”, the Board has no reason to believe that the consumers are likely to confuse a source of goods bearing the opposed mark “DMINI” with BMW.

Based on the foregoing, the Board decided to dismiss the entire opposition and declared the validity of the mark “DMINI” as status quo.

LEPUS vs. LEPS

In an appeal decision, the Japan Patent Office (JPO) overturned the examiner’s rejection and decided to register trademark “LEPS” by finding dissimilarity to senior registration for mark “LEPUS” even if both marks designate similar goods in class 12.
[Appeal case no. 2019-6626, Gazette issued date: March 27, 2020]

LEPS

Applicant, GS Yuasa Corporation, filed a trademark application for term “LEPS” in standard character over solar batteries, power distribution or control machines, and apparatus, rotary converters, phase modifiers of class 12 on December 18, 2017 (TM application no. 2017-165431).

JPO examiner rejected the applied mark in contravention of Article 4(1)(xi) of the Trademark Law by citing senior trademark registration no. 3194818 for mark “LEPUS”

Article 4(1)(xi) is a provision to prohibit registering a junior mark which is identical with, or similar to, any senior registered mark.

LEPUS

Cited mark “LEPUS” (see below), owned by Mitsubishi Motors Corporation, has been registered since September 1996 over automobiles and their parts and fittings, two-wheeled motor vehicles, bicycles, and their parts and fittings, AC motors or DC motors for land vehicles in class 12.

On April 25, 2019, GS Yuasa filed an appeal against the rejection and argued dissimilarity of the marks.

Appeal Board decision

In the decision, the Appeal Board held that:

From appearance, even if both marks start with “LEP” and end with “S”, with or without “U” in the middle of a short word consisting of four or five letters would be anything but negligible. Because of it, the marks as a whole give rise to a distinctive visual impression in the minds of relevant consumers. Accordingly, both marks are unlikely to cause confusion from appearance.

Applied mark “LEPS” is pronounced as “le-ps”. In the meantime, cited mark “LEPUS” shall be “le-pəs”. The difference in the 2nd sound, “p” and “pə”, would be influential in the overall pronunciation given both marks aurally consist of just three sounds. Due to the difference, both sounds can be distinguishable in tone and linguistic feeling when pronounced at a time.

Conceptually, applied mark is incomparable with cited mark since both marks would not give rise to any specific meaning at all.

Based on the foregoing, the Board concluded: “applied mark “LEPS” would be deemed dissimilar to cited mark “LEPUS” from the global appreciation of the visual, aural and conceptual similarity of the marks in question, and based on the overall impression and association given by the marks to relevant traders and consumers with ordinary care“.

Consequently, the Board reversed the examiner’s rejection due to the dissimilarity of the marks even if the goods in question are similar and allowed registration of the applied mark (TM registration no. 6234714).
