The Korean Patent Court has been increasingly using survey results as evidence to establish the distinctiveness of a trade mark. Distinctiveness is a requirement for registration and is often one of the main issues in trade mark infringement disputes. Until recently, the Korean Patent Court was reluctant to accept surveys as evidence to support distinctiveness, even though surveys may be the best method to show consumers' recognition of a trade mark. A main reason for the reluctance of the Patent Court was because the Court often found the surveys were designed to favour the plaintiff and could be interpreted many different ways.
