[Trademarks] IP High Court, Reiwa 6 (Gyo-Ke) 10101, “SCANTECH” (Presiding Judge Masuda)

Invalidation not established (Trademark Act Article 4(1)(x), (xv))

Well-known status of the cited “SCANTEC” mark: Not established

(1) Domestic market share

The plaintiff’s data concerned its products collectively, not the products bearing the cited mark alone.

Lower-priced “WEBSENSOR” and other products did not bear the cited mark and did not establish its well-known status.

(2) Google search results

A large number of search results does not, by itself, establish well-known status.

(3) Exhibition participation

Participation once or twice annually cannot be regarded as frequent; there was also no evidence of visitor numbers at the plaintiff’s booth.

(4) Newspaper and specialist-journal coverage

About 12 appearances over nearly 30 years (industry newspapers) and about 40 over 27 years (specialist journals) were sporadic, and detailed circulation figures were unknown.

(5) Patent specifications

Mention of a product name in patent specifications is not directly linked to well-known status.
