The Japan Patent Office (JPO) reversed the examiner’s rejection of TM App no. 2023-61383 for composite mark “PCA” filed by Porshe Japan on account of dissimilarity to earlier trademark registrations for word mark “PCA”.
[Appeal case no. 2024-3079, decided on February 17, 2025]
PREMIUM CHARGING ALLIANCE “PCA”
Porsche Japan K.K., a wholly-owned subsidiary of Porsche AG as an official distributor of Porsche vehicles in Japan, filed trademark application for composite mark “PCA” as shown below with the JPO for use on ‘compute programs’ in class 9 and ‘computer software design; computer programing; maintenance of computer software; providing computer programs on data networks’ in class 42 on June 5, 2023.

Porsche Japan has launched a project to expand the network of 150kW fast charging stations across Japan by forming an alliance with Audi in April 2022. The applied mark is used to indicate the project.
JPO examination
On November 21, 2023, the JPO examiner rejected the applied mark due to a conflict with earlier trademark registration nos. 1738222, 5762134 and 5764544 for word mark “PCA” in class 9 and 42 owned by PCA Corporation based on Article 4(1)(xi) of the Trademark Law.

In the refusal decision, the examiner stated that the element “PCA” in the upper line of the applied mark is dominant in the overall visual impression. If so, the applied mark is confusingly similar to the cited marks, even though there is a difference in appearance, since both marks give rise to the same sound.
Porsche Japan filed an appeal against the rejection on February 21, 2024, requesting that the decision be set aside.
Appeal Board decision
The JPO Appeal Board found the applied mark should not be dissected into individual parts from its overall configuration. Relevant consumers would recognize the term “PCA” in the upper line as an abbreviation of the term “PREMIUM CHARGING ALLIANCE” in the lower line. Both the term “PCA” and “PREMIUM CHARGING ALLIANCE” would not give rise to any specific meaning.
In assessing similarity of the marks, the Board held there is no clear distinction in appearance between the marks as a whole. Phonetically, the applied mark is dissimilar to the cited marks on account of the sound arising from the term “PREMIUM CHARGING ALLIANCE”. The conceptual aspect does not have impact on the assessment of similarity, since both marks are meaningless.
Based on the above findings, the Board found the examiner erroneously applied Article 4(1)(xi) and declared registration of the applied mark due to dissimilarity to the earlier mark “PCA”.
