This case illustrates how the Japan Patent Office (JPO) evaluates trademark similarity where two marks may share the same pronunciation but differ in appearance and meaning. It demonstrates that phonetic similarity alone does not necessarily result in a finding of similarity under Article 4(1)(xi) of the Japanese Trademark Act.

1. Application Details

• Mark: GENIUS
• International Registration No.: 1630566
• Designated Goods: Goods in Classes 9 and 10, including computer hardware and software for cancer detection, diagnosis and treatment, laboratory apparatus for analyzing cells, and electronic medical imaging and image-processing apparatus.

2. Refusal by the JPO Examiner

The application was refused on two grounds:

• Article 6(1) – lack of clarity in part of the specification of goods; and
• Article 4(1)(xi) – similarity to prior registered trademarks.

The examiner cited the following earlier trademarks:

Cited Mark 1

• Registration No.: 4952239
• Mark: Stylized “Genius” with a device element
• Designated Goods: Goods in Class 9.

Cited Mark 2

• Mark: GEENIUS
• International Registration No.: 1041476
• Designated Goods: Goods in Classes 1, 5 and 10.

The examiner considered the applied-for mark to conflict with these earlier registrations under Article 4(1)(xi).

3. Appeal to the JPO Trial and Appeal Board

An appeal was filed against the refusal.

• Appeal No.: 2024-650051

The case arose from an international trademark registration designating Japan. The JPO had issued a provisional refusal, followed eventually by a final refusal, which was appealed to the JPO Trial and Appeal Board.

4. Decision of the Appeal Board

The JPO Appeal Board reversed the refusal.

(1) Clarity of the Designated Goods

The examiner had found that certain Class 9 goods, particularly electronic imaging and image-processing apparatus for cytology and histology, were not sufficiently clear.

The Board disagreed and found that the wording sufficiently identified the nature and scope of the goods. Accordingly, the application satisfied Article 6(1).

(2) Cited Mark 1

During the appeal proceedings, the registration for Cited Mark 1 had been surrendered and cancelled.

Therefore, the Article 4(1)(xi) refusal based on Cited Mark 1 was no longer applicable.

(3) Comparison of “GENIUS” and “GEENIUS”

The principal issue was therefore the comparison between:

• GENIUS – the applied-for mark; and
• GEENIUS – Cited Mark 2.

The Board found that GENIUS is a familiar English word meaning “genius”, giving rise to the pronunciation “GENIUS” and the concept of a genius or highly gifted person. In contrast, GEENIUS is not an established dictionary word in Japan and therefore conveys no specific concept.

In terms of appearance, the marks consist of only six and seven letters respectively, and the difference between “GE” and “GEE” at the beginning of the marks can therefore be clearly recognized.

In terms of pronunciation, the marks may both be pronounced “GENIUS” in Japanese. However, GEENIUS may alternatively be pronounced differently, in which case the initial sounds are clearly distinguishable.

Most importantly, the Board concluded that the common pronunciation did not outweigh the clear differences in appearance and concept.

Considering appearance, pronunciation and concept as a whole, the marks were therefore found not similar.

5. Outcome

The Board concluded that:

• the specification satisfied Article 6(1);
• the refusal based on Cited Mark 1 had been resolved because that registration had been cancelled; and
• GENIUS and GEENIUS were not similar under Article 4(1)(xi).

Accordingly, the original refusal was set aside, and the trademark GENIUS was allowed to proceed toward registration.

Key Point for Foreign Applicants

1. Identical pronunciation does not automatically mean similarity

Even where two trademarks may be pronounced identically in Japanese, the JPO will consider their appearance and meaning as part of the overall assessment.

2. Visual differences can be particularly significant for short word marks

Because GENIUS and GEENIUS are relatively short, the additional “E” near the beginning of GEENIUS was readily noticeable.

3. Conceptual differences can outweigh phonetic similarity

GENIUS has the familiar meaning “genius,” whereas GEENIUS was regarded as a coined term with no specific meaning. This conceptual difference contributed significantly to the finding of non-similarity.

4. The current status of cited registrations matters

A refusal under Article 4(1)(xi) may be overcome if the cited registration ceases to exist during the proceedings.

Practical takeaway

In Japan, phonetic identity alone is not decisive in determining trademark similarity.

Even where two marks may generate the same pronunciation, a refusal may be overcome when clear visual and conceptual differences outweigh the phonetic similarity. The GENIUS / GEENIUS decision is a useful example of the JPO’s overall assessment of appearance, pronunciation and concept rather than reliance on any single factor.
