In a recent appeal decision, the Japan Patent Office (JPO) upheld the examiner’s refusal to TM App no. 2024-134546 for wordmark “SHINOBI” after finding the designated game software similar to the cited electronic devices and display monitors.
[Appeal case no. 2025-9765, decided on May 22, 2026]
SHINOBI by SEGA
Sega Corporation, a Japanese video game company, filed an application to register the word mark “SHINOBI” in standard characters covering “game programs for mobile phones or computers; computer game software; virtual reality game software” in class 9 with the JPO on December 13, 2024 [TM App no. 2024-134546].
JPO Examination
On March 24, 2025, the examiner rejected the mark based on Article 4(1)(xi) of the Japan Trademark Law by citing IR no. 1659265 for word mark “SHINOBI” in relation to the goods of “Electronic devices for displaying, editing, recording, encoding, storing, transferring, transmitting or reproducing data, electronic data, video and audio excluding electronic devices for playing video games; display monitors; apparatus for the reproduction of sound or images” in class 9.
The examiner considered the goods similar despite the applicant’s contention that game software and electronic devices are fundamentally different products produced and sold by different industries.
To contest, SEGA filed an appeal against the rejection on June 24, 2025, and challenging the examiner’s finding of similarity between the goods.
Appeal Board decision
The Appeal Board reiterated the long-established principle that the similarity of goods does not depend on whether consumers would confuse the goods themselves.
Instead, the relevant question is whether the use of identical or similar trademarks on those goods would lead consumers to believe that the goods originate from the same commercial source.
In making that assessment, the JPO considered factors such as:
• production channels;
• sales channels;
• quality and characteristics;
• intended purpose;
• consumer groups; and
• the relationship between finished products and components.
Hardware and software as closely related goods
The Appeal Board first observed that the cited goods essentially covered general-purpose electronic devices such as computers and smartphones, as well as display monitors.
Game software, by its nature, is executed on computers, smartphones, and similar electronic devices. Display monitors are likewise commonly used when operating computer games.
Accordingly, the JPO found that the cited electronic devices and monitors are products used to run or utilize the applicant’s game software, creating a close commercial relationship between the goods.
Production and sales channels
The applicant argued that game software is typically produced by game developers, whereas computers and monitors are manufactured by electronics companies.
However, the JPO relied on marketplace evidence showing that certain businesses manufacture and offer both gaming software and computer-related hardware products.
The Appeal Board therefore concluded that the production sources may overlap.
The same reasoning was applied to sales channels.
According to the JPO, game software, computers, and display monitors are frequently sold through the same retail outlets, including large electronics stores. In many cases, the products are displayed in close proximity and may even be offered by the same supplier.
Purpose and consumers
The Board also emphasized that gaming monitors are widely marketed and sold specifically for gaming purposes.
Moreover, although the cited specification expressly excluded dedicated video game consoles, it still encompassed general-purpose computers and smartphones capable of running games.
As a result, both categories of goods may, in certain circumstances, share the same gaming-related purpose.
The Board further noted that the relevant consumers substantially overlap, since both goods target ordinary consumers who use computers and similar electronic devices.
Software and hardware: a relationship close to components and finished products
Notably, the Board also addressed the relationship between software and hardware.
While acknowledging that software and hardware are not literally a finished product and its component, the JPO nevertheless found them to be closely comparable to such a relationship.
Game software is installed on electronic devices and used in conjunction with monitors. In practice, the products function together as part of a single user experience.
This functional interdependence weighed heavily in favor of finding similarity.
Conclusion
Taking all relevant factors into account, the Appeal Board concluded that the designated game software and the cited electronic devices and display monitors constitute similar goods. The examiner therefore did not err in refusing the application under Article 4(1)(xi) of the Trademark Act.
