In the administrative litigation regarding the invalidation of the device mark No. 8262105 of C&S Paper Co., Ltd., the Supreme Court overturned the second-instance judgment, ultimately affirming the mark's distinctiveness and clarifying the core principles for determining inherent distinctiveness in marks. The retrial applicant, C&S Paper Co., Ltd. (hereinafter referred to as "C&S Paper"), owns the mark No. 8262105 for logo with colour claim.
