The Japan Patent Office (JPO) dismissed an opposition filed by Comité Interprofessionnel du Vin de. Champagne (C.I.V.C.) against TM Reg no. 6843113 for wordmark “yes no champagne” in Class 33 by stating that Japanese ownership of the contested mark would neither harm the friendly relationship between Japan and France, nor public sentiment.
[Opposition case no. 2024-900238, decided on June 24, 2025]
YES NO CHAMPAGNE
ZERU Co., Ltd. filed a trademark application for word mark “yea no champagne” and its Japanese transliteration arranged in two lines (see below) for use on wines in Class 33 with the JPO on November 16, 2023. [TM App no. 2023-133081]

On May 31, 2024, the JPO examiner issued an office action based on Article 4(1)(xvi) and (xvii) of the Japan Trademark Law.
Article 4(1)(xvi) prohibits registering a mark that could mislead consumers about the quality of the goods.
Article 4(1)(xvii) prohibits the registration of any mark comprised of a mark indicating the place of origin of wines or spirits from the World Trade Organization member that has prohibited its use on wines or spirits not originating from its region.
Since, the applicant restricted the designated goods in Class 33 to wines with the protected appellation of origin “Champagne” as a response to the office action, the JPO examiner granted registration of the mark. Subsequently, the mark was published for post-grant opposition on September 20, 2024.
Opposition by C.I.V.C.
On November 21, 2024, just before a lapse of the two-month statutory opposition period, Comité Interprofessionnel du Vin de. Champagne (C.I.V.C.) filed an opposition and claimed cancelation of the contested mark based on Article 4(1)(vii) of the Trademark Law.
Article 4(1)(vii) provides that a mark shall not be registered if it is likely to cause damage to public policy.
In the opposition brief, the C.I.V.C. argued that any mark containing the term “Champagne” should not be owned by an entity with no connection to or place of business in the region. Such ownership would likely to lead to free-riding on a famous geographical indication, diluting its source-identifying value and ultimately dishonoring France and its citizens, contrary to international faith.
JPO decision
The JPO Opposition Board admitted the remarkable reputation of the geographical indication “Champagne” among the general public, which was acquired through substantive use and marketing efforts made by the C.I.V.C. and other relevant organizations. The Board also found that the term “Champagne” and Champagne wines are cultural products of France and of extremely high significance to the country and its citizens.
Meanwhile, the Board noted that champagne wines are widely distributed in Japan, and that relevant traders commonly use the term “champagne” to refer to the wines.
Taking account of long-lasting trade practice that the term “Champagne” has been commonly used among traders of the goods in question, it would not anything but disorder public policy or moral to use the contested mark that contains the term “Champagne” in connection with wines with the protected appellation of origin “Champagne.”
If so, the Board finds no reason to believe that registration and use of the contested mark by the applicant is likely to harm the friendly relationship between Japan and France or public sentiment.
Based on the above findings, the Board made a decision to dismiss the opposition entirely.
