On July 25, 2025, the Japan Patent Office (JPO) granted trademark registration for the three-dimensional (3D) shape of Ezaki Glico’s iconic “Pocky” cookie, recognizing that the shape had acquired distinctiveness in relation to chocolate confections in Class 30 [TM Reg. No. 6951539].
Ezaki Glico’s Pocky
Pocky, first introduced in 1966 by Ezaki Glico—one of Japan’s leading confectionery manufacturers—is a slender biscuit stick coated in chocolate, with the lower end intentionally left bare to allow for easy handling without getting chocolate on the fingers.

On March 13, 2024, MARKS IP LAW FIRM, acting as trademark counsel to Ezaki Glico, filed a 3D trademark application with the JPO for the shape of the Pocky cookie, covering confectionery in Class 30 [TM App. No. 2024-26132].

Acquired Distinctiveness
During the substantive examination, as anticipated, the JPO issued a Notification of Reasons for Refusal pursuant to Article 3(1)(iii) of the Japan Trademark Law. This provision bars registration of marks that consist solely of indications commonly used to designate, inter alia, the place of origin, quality, raw materials, intended purpose, shape (including packaging), price, or method/time of production or use.
In response, we submitted that the Pocky cookie’s 3D shape had, through long-standing and widespread use, come to function as a source identifier. Accordingly, it should qualify for exception under Article 3(2) of the Japan Trademark Law, which permits registration of marks otherwise barred under Article 3(1)(iii)–(v), provided that the mark has acquired distinctiveness among relevant consumers.
To substantiate the claim of acquired distinctiveness, we submitted extensive evidence, including market research targeting 1,036 men and women aged 16 to 79. Remarkably, 91.6% of respondents, when shown the 3D shape of the Pocky cookie without any accompanying text, identified it as “Pocky” or “Pocky chocolate” in response to an open-ended question.
JPO Decision
Following the submission of evidence and subsequent restriction of the designated goods to “chocolate confections” in Class 30, the JPO approved the registration on June 24, 2025 by admitting acquired distinctiveness of the 3D mark.

To date, the JPO has granted a total of eight registrations for the 3D shape of confectionery products. Of these, only two—prior to Pocky—were registered on the basis of acquired distinctiveness under Article 3(2). The Pocky case therefore represents only the third such registration in Japan and is particularly noteworthy given the simplicity and lack of ornamentation in the claimed product shape.
