[Trademark] 2023 (Gyo-Ke) 10087, “Sankin Kogyo” Case <Hibiku Shimizu>
The “Sankin” portion of the trademark at issue, “Sankin Kogyo” (standard characters), was widely known as indicating the goods of another company (the plaintiff's Japanese subsidiary).
“Sankin” can be observed separately.
⇒ It is identical to the cited invention “Sankin,” and the marks are similar overall (violation of Article 4(1)(xi)). In addition, there is a likelihood of confusion (violation of Article 4(1)(xv)).
Translator’s notes (editorial)
SOURCE TERMINOLOGY: The source says cited invention in its trademark-similarity conclusion. This is translated literally rather than silently changed to cited trademark. The exact Japanese mark is retained in the preserved Japanese source fields; English body uses romanization.
