On October 26, 2020, the Law Times reported that "Lee & Ko won an appeals case where its client, Haeundae Amso Galbijip, a beef rib restaurant in Busan, sought prohibition of unfair competition activities against Mr. A, whose restaurant in Yongsan-gu, Seoul used the same name as the plaintiff.”

Lee & Ko attorney Un Ho Kim, who was in charge of this case, remarked that “Despite the fact that the unauthorized use of menus, trade names, and brands of other restaurants in the food service industry is wrongful activity, it had not been regarded as a domain for legal judgment. As a result, original restaurants had to watch their achievements being appropriated by other restaurants without any means of recourse, and merely had to appeal to the other party’s sense of business ethics (sang-do). This ruling makes it clear that such unauthorized copying is an unfair act that is not allowed under the law.” Mr. Kim further added, “This legal precedent will help to establish fair competition in the food service industry.”
