Girls' Generation Awarded Sole Use Of Name In Court
A 2007 court case came to an end this week, when the South Korean Supreme Court determined that Girls' Generation's public appeal is so great that the girl group's agency, SM Entertainment, had the sole use of the name "Girls Generation" while promoting the group. The lawsuit was brought about after a retailer registered the trademark ten days after Girls' Generation debuted in 2007 and SM Entertainment countered the trademark.

The Supreme Court determined that girl group's "high level of brand awareness" could lead to potential confusion from consumers, resulting in the decision that Girls' Generation alone could use their name.
