IP High Court Decision, 2022Heo1216 (Case Concerning Trademark)

The registered service mark at issue falls under the latter part of Article 34(1)12 and Article 34(1)13 of the Trademark Act in relation to the prior-used service mark, and therefore its registration must be invalidated (having acknowledged the invalidation grounds under the latter part of Article 34(1)12 and Article 34(1)13 of the Trademark Act, it is unnecessary to further examin the invalidation grounds under the former part of Article 34(1)(12), which is in an selective relationship).
