SERAPIAN Successful in Registering iconic MOSAICO braided pattern as trademark

The Italian-based fashion house Stefano Serapian S.r.l. was successful in an appeal to overturn the examiner’s rejection of TM App no. 2022-131488 for the Serapian’s signature “Mosaico” leather pattern in Class 18.
[Appeal case no. 2023-16337, decided on December 17, 2025]


SERAPIAN MOSAICO

Stefano Serapian S.r.l. filed a trademark application for a braided pattern (see below) for use on bags, suitcases, tote bags, backpacks, key cases, porches, wallets, coin cases, and handbags in Class 18 with the JPO on November 17, 2022 [TM App no. 2022-131488].

The Serapian Mosaico pattern is known for its iconic hand-weaving technique, which dates back to 1947 and serves as an emblem of the Italian luxury brand, Serapian.


JPO Examination

On June 26, 2023, the examiner rejected the mark based on Article 3(1)(vi) of the Japan Trademark Law by finding that:

The applied-for mark represents a continuous and repetitive geometric pattern consisting of a white square with a vertical line in the middle and a black square in a diagonal position. As a whole, it will be perceived merely as a decorative background design. Besides, there is no distinctive element that identifies the source of the goods in question. Consequently, consumers are unable to recognize it as a source indicator due to its lack of inherent distinctiveness.

Serapian filed an appeal against the rejection on September 27, 2023, to dispute the inherent distinctiveness of the mark based on substantial use and advertising of the Mosaico collection in Japan since 2014.


JPO Appeal Board Decision

The JPO Appeal Board noted the following facts.

  • Founded in 1928, the applicant is known for its line of bags favored by the late British actress Audrey Hepburn. The applicant’s bags, which depict the applied-for mark and were designed in 1947, have been sold nationwide in Japan for over 10 years and have been distributed in Japan since 2014.
  • Major fashion magazines and online articles have featured the bags and their iconic “MOSAICO” pattern design.
  • The bags are also sold in major department stores and online malls. Despite being expensive and high-end goods, annual sales exceeded JPY 50 million in 2023 and JPY 9 million in 2024.
  • A discretionary survey by the Board did not reveal the actual use of a similar pattern by others.

Based on the foregoing, the Board found that relevant consumers and traders can distinguish the applicant’s goods from others based solely on the Mosaico pattern.

Therefore, since the applied-for mark is not subject to Article 3(1)(vi) of the Japan Trademark Law, the Board overturned the examiner’s rejection.

Serapian Loses Trademark Opposition against S device mark

The Italian-based fashion house Stefano Serapian S.r.l., known for its briefcases, handbags and purses opposed the registration in Japan of the trademark S logo owned by the Japanese company, Kabushiki Kaisha Overseas.

 

Opposed mark

Overseas filed an application to register S logo (see below) designating, among others, bags, purses, pouches and leather goods in class 18 on April 27, 2017. Going through substantive examination at the Japan Patent Office (JPO), it was registered on October 20 of that year (TM Reg no. 5990450).

Serapian Opposition

A trademark opposition proceeding filed on January 15, 2018, Serapian contended that opposed mark is confusingly similar to its registered famous “S” device mark (see below) by citing its owned IR no. 1117130 and thus shall be cancelled in violation of Article 4(1)(xi) and (xv) of the Japan Trademark Law.

 

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) provides that a mark shall not be registered where it is likely to cause confusion with other business entity’s well-known goods or services, to the benefit of brand owner and consumers.

Theoretically, Article 4(1)(xv) is applicable to the case where a mark in question is deemed dissimilar to well-known brand, but still likely to cause confusion because of a high degree of popularity and reputation of the brand.

 

The Ruling

The Opposition Board of JPO negated a certain degree of popularity and reputation of Serapian’s “S” device mark, stating that produced materials are insufficient and non-objective to demonstrate famousness of the cited mark.

Besides, the Board found that both marks are sufficiently distinguishable from appearance in view of overall configuration. From phonetic and conceptual points of view, it is apparent that respective mark would not be perceived as an alphabetical letter ‘S’, but a geometric figure device without any specific concept and pronunciation. If so, both marks would not give rise to similar appearance, sound and meaning at all.

Even if taking account of originality of “S” device mark, as long as it remains unclear whether Serapian “S” device mark has become popular among relevant consumers in Japan, the Board had no reason to admit a likelihood of confusion.

As a conclusion, the Board decided opposed mark is not subject to Article 4(1)(xi) and (xv) of the Trademark Law and dismissed the opposition accordingly.
