In a trademark opposition contesting the validity of the mark “CHANDLER,” the Japan Patent Office (JPO) dismissed the oppositions claimed by Group Authentic, LLC and David Chandler.
[Opposition case nos. 2023-900161, 2023-900212, and 2023-900213, decided on July 18, 2024]


Opposed mark

La Potencia LLC filed three trademark applications with the JPO on September 6, 2022 for the wordmark “CHANDLER”, “CHANDLER BATS,” and a composite mark consisting of the word “Chandler” in script with a “C” shaped design representing a bat knob inside for use on various goods and retail or wholesale services related to baseball in Classes 9, 18, 25, 28 and 35.

The marks were all granted for registration and published for post-grant opposition accordingly.


Opposition by David Chandler

Group Authentic, LLC and David Chandler jointly filed a trademark opposition against the marks before the lapse of two months from the publication date at the JPO.

In the opposition, they argued “Chandler” has been highly known in relation to baseball bats to indicate a name of David Chandler who has manufactured hundreds of models of baseball bats for Major League Baseball players since 2009. The opposing parties has no intention to give a consent for La Potencia LLC to register the opposed marks in Japan. Under the circumstance, the opposed mark shall be cancelled in contravention of Article 4(1)(vii) and (viii) of the Japan Trademark Law.

Article 4(1)(vii) prohibits any mark likely to cause damage to the social and public interest and disrupt the order of fair competition from registration.

Article 4(1)(viii) is a provision to prohibit registration of trademark that contains the representation or name of any person, famous pseudonym, professional name, or pen name of another person, or famous abbreviation thereof.


The JPO decision

The JPO Opposition Board found that the mere fact and documents regarding the USPTO’s rejection of US App Nos. 97313019, 97312938, and 97313467 for the opposed marks by the USPTO were insufficient to establish a high degree of popularity and reputation of the mark “Chandler” as an abbreviation of Mr. David Chandler.

Based on the above finding, the Board has no reason to believe a lack of the consent would cause damage to the social and public interest and disrupt the order of fair competition.

To the extent that insufficient evidence has been produced to establish that the mark “Chandler” is famous as an abbreviation of Mr. David Chandler, it is inadmissible to find that the opposed marks contain a famous abbreviation of a living person.

In light of the foregoing, the Board decided the opposed marks shall not be cancelled based on Article 4(1)(vii) and (viii), and dismissed the entire oppositions.
