Daiso filed a lawsuit for infringement of a service mark right against the user of a service mark, ‘Dasaso,’ by reason for the similarity of ‘Daiso’ and ‘Dasaso,’ and lost the first trial. AIP newly represented Daiso at appeal trial and won the trials at the Seoul High Court and the Supreme Court. This is a case that prohibited a company from taking advantage of a well-known brand and thereby engaging in unfair competition, and that protected a right-holder of a well-known service mark.
