In several cases, a trade mark cannot be registered, even if it has sufficient distinctiveness, because there is an identical or similar trade mark previously registered or applied for to distinguish the same goods or services. Even though the Trade Mark Law does not specifically use the terms "confusion or likelihood of confusion", its main purpose is to avoid this situation. Section 3 of the Law says that a trade mark identical or similar to one previously registered or applied for to distinguish the same goods or services cannot be registered.
