Yves Saint Laurent Failed Opposition against USL monogram

The Japan Patent Office (JPO) did not support Yves Saint Laurent in their trademark opposition against TM Reg no. 6666672 for the “USL” monogram in class 25. The JPO found no similarity or unlikelihood of confusion with the famous “YSL” monogram.
[Opposition case no. 2023-900076, decided on January 18, 2024]

Opposed mark

Marusho hotta Co., Ltd. filed a trademark application for mark consisting of the “USL” monogram and a circle device (see below) in relation to outer clothing of class 25 with the JPO on August 18, 2022.

The applicant uses the mark on knitted wear, pants and caps as a logo of “UN-USELESS” brand.

The JPO examiner, without raising any objections, granted protection of the mark on January 25, 2023. Subsequently, the mark was published for post-grant opposition on February 6, 2023.

Opposition by Yves Saint Laurent

The renowned French luxury fashion house Yves Saint Laurent has filed a trademark opposition with the JPO on April 6, 2023 and claimed cancellation of the opposed mark in contravention of Article 4(1)(xi) and (xv) of the Japan Trademark Law by citing their earlier trademark registrations for the famous “YSL” monogram.

Yves Saint Laurent argued the monogram of opposed mark can be recognized a combination of three letters, “Y”, “S” and “L”. If so, the opposed mark has the same sound and spelling with the famous “YSL” monogram. Because of their close resemblance, consumers are likely to confuse a source of the goods bearing the opposed mark with Yves Saint Laurent.

JPO decision

The JPO Opposition Board had a view that relevant consumers with ordinary care would not conceive a combination of three letters, “Y”, “S” and “L” at the sight of the monogram of the opposed mark, but “U”, “S” and “L”.

Based on the finding, the Board held both marks are visually dissimilar by means of clear difference in the initial letter, font design and overall configuration. Aurally, there is a distinction between the ‘u’ and ‘y’ sounds at the beginning, and this contrast significantly affects the overall impression by taking account of a relatively short six-syllable structure. As both marks are meaningless, the concepts are incomparable.

If so, the Board has no reason to believe the opposed mark is similar to the YLS monogram and thus likely to cause confusion with Yves Saint Laurent even when used on the goods in question.

In conclusion, the Opposition Board determined that the opposed mark is not subject to Article 4(1)(xi) and (xv) and has therefore decided to dismiss the opposition entirely.

Lous Vuitton lost in a trademark battle over LV monogram

The Japan Patent Office (JPO) dismissed a trademark opposition against TM Reg no. 6685241 in class 18 and 25 filed by LOUIS VUITTON MALLETIER due to dissimilarity to and unlikelihood of confusion with the famous “LV” monogram.
[Opposition case no. 2023-900138, decided on January 12,2024]

Opposed mark

A Japanese individual filed a mark consisting of “MARU des VINTAGES”, “KYOJI MARUYAMA”, and a monogram-like device (see below) for use on bags, leather products, clothing, footwear and other in class 18 and 25 on July 22, 2022 with the JPO.

Seemingly, the device looks like a motif made by overlapping “V” and other characters, “LI”, “LA” or “M”.

In the course of substantive examination, the JPO examiner raised his objection just to confirm if the applicant has a consent from the person named “KYOJI MARUYAMA”.

Upon confirmation, the examiner granted protection of the mark on March 10, 2023 and the JPO published it for a post-grant opposition on April 7, 2023.

Opposition by Lous Vuitton

On June 7, 2023, just before the lapse of two-month opposition period counting from the publication date, LOUIS VUITTON MALLETIER filed an opposition with the JPO and claimed that the opposed mark shall be cancelled in contravention of Article 4(1)(xi) and (xv) of the Japan Trademark Law by citing IR no. 1127687 for the famous “LV” monogram in classes 18, 25 and others effectively registered in Japan since April 2014.

Article 4(1)(xi) is a provision to prohibit the registration of a junior mark that is identical with, or similar to, any senior registered mark.

Article 4(1)(xv) provides that a mark shall not be registered where it is likely to cause confusion with other business entities’ well-known goods or services.

Louis Vuitton argued the monogram-like device of opposed mark is confusingly similar to the world-famous “LV” monogram from a visual point of view. If so, relevant consumers are likely to confuse a source of the goods in class 18 and 25 bearing the opposed mark with Louis Vuitton even if the opposed mark contains distinctive literal elements, “MARU des VINTAGES”.

JPO decision

The JPO admitted a high degree of reputation and popularity of the LV monogram among relevant consumers as a source indicator of Louis Vuitton. The Opposition Board considered it unreasonable to assess similarity of mark simply by comparing respective mark in its entirety. The Board found the monogram-like device shall be a prominent portion of the opposed mark from visual impression.

However, the Board negated similarity between the device and the LV monogram by stating that:

Even if the device undoubtedly contains the letter “V” in its composition, it is impossible to specify what represents as a whole. Due to the reason, there is clear distinction in configuration, overall impression between two devices. If so, the Board has a reason to believe there is no likelihood of confusion in appearance.

The LV monogram gives rise to a sound of ‘elˈviː’ and a meaning of “Louis Vuitton”. In the meantime, the opposed device would not have any specific sound and meaning. Therefore, it is obvious that two devices are dissimilar from aural and conceptual points of view.

In view of a low degree of similarity between the monogram-like device and the “LV” monogram, difference caused by distinctive literal elements “MARU des VINTAGES”, “KYOJI MARUYAMA” of the opposed mark, the Board found relevant consumers are unlikely to confuse or associate the goods in question bearing the opposed mark with Lous Vuitton.

Based on the foregoing, the Opposition Board concluded the opposition’s arguments groundless and decided to dismiss the entire opposition.


In a recent administrative decision, the Appeal Board of Japan Patent Office (JPO) disaffirmed the examiner’s refusal and held a composite mark, consisting of words “PERFECT GEAR AGENCY” and a monogram “PGA”, is dissimilar to the senior registered word mark “PGA” owned by Professional Golf Association.
[Appeal case no. 2019-10638, Gazette issued date: September 25, 2020]


Disputed mark, see below, was applied for registration in relation to retail or wholesale services for various goods, e.g. foods and beverages, footwear, bags, automobiles in class 35 on January 24, 2018.

The disputed mark consists of the “PGA” monogram and the words “PERFECT GEAR AGENCY” on the right. The initial letter of the respective term is colored in red. Apparently, the monogram comes from an initial letter of each word “PERFECT”, “GEAR” and “AGENCY”.

JPO Examiner rejected the disputed mark by citing several senior trademark registrations for a wordmark “PGA” in various classes owned by Professional Golf Association.

In Japan, retail or wholesale service in respect of specific goods is deemed similar to the goods or its equivalent. For example, retail service in respect of sporting goods (class 35) and sporting goods (class 28) is deemed similar.

That being the case, the applicant filed an appeal against the refusal and contended dissimilarity of the mark.

JPO decision

The Appeal Board found that the “PGA” monogram and words “PERFECT GEAR AGENCY” can be separably seen from a visual point of view. Besides, the “PGA” monogram per se does not give rise to any specific meaning. It is unknown whether relevant Japanese consumers have been familiar with the words “PERFECT GEAR AGENCY” as a whole. If so, the words do not give rise to a specific meaning as well.

By taking account of the above, the Board pointed out the disputed mark shall be pronounced as “PERFECT GEAR AGENCY”, but has no meaning.

Based on the foregoing, the Board concluded the refusal shall be disaffirmed since the examiner erroneously found that the disputed mark gives rise to a pronunciation of “PGA” from the “PGA” monogram.

Louis Vuitton victory in trademark battle for remake use

In a trademark battle involving famous Louis Vuitton Monogram for remake use, the Japan IP High Court ruled in favor of Louis Vuitton and ordered appellant to pay 1.7 million JP-Yen for damages on October 23, 2018.

Custom-made Remake

Appellant has produced shoes, caps and other fashion items by making use of material of secondhand Louis Vuitton goods (see below) and promoted the items as a custom-made remake, e.g. LOUIS VUITTON REMAKE DENIM CAP/BLUE, through internet.

Unfair Competition Prevention Act

Louis Vuitton filed a lawsuit and demanded to stop selling the items as well as payment for the damage on the grounds that appellant’s act constitutes unfair competition under Article 2(1)(ii) of the Japan Unfair Prevention Act.

Article 2(1)(ii) of the Unfair Competition Prevention Act is a provision to prohibit any person from using a famous source indicator of another person without permission.


Appellant argued they become popular among relevant consumers as a business entity to produce a custom-made remake from secondhand of genuine brand. If so, since consumers are fully aware that the items are remake, neither faked goods nor brand-new article, confusion is unlikely to happen in the mind of consumers. Besides, appellant insisted as long as the Louis Vuitton Monogram is not used as a source indicator but design, the Unfair Competition Prevention Act is not applicable to the items.

IP High Court decision

The IP High Court decisively dismissed appellant’s allegations and decided the monogram on the items still plays a role of source indicator in view of remarkable reputation of Louis Vuitton Monogram. It can be easily presumed that average consumers at sight of the items shall conceive Louis Vuitton. Even if the items are sold as a custom-made remake or with any description to appeal the items made from secondhand, such facts will not affect the decision on the merit.
[Heisei 30 (Ne)10042]

The Unfair Competition Prevention Act is essential to the case where actual confusion would not happen in fact regardless of unauthorized commercial use of famous brand.
