Only the proprietor of a registered trade mark may take steps to protect his mark under the Nigeria Trade Marks Act. Investment in innovation and goodwill in one’s trading name may be wasted unless one takes steps to protect oneself against competitors seeking to take unfair advantage of another’s efforts or reputation.
An unregistered trademark in Nigeria which has been long in use and is widely known to be the mark of a trademark owner may only be protected in a common law action for passing off. Legal consequences and remedies available for enforcing a trade mark in Nigeria include action for passing off, damages, infringement and opposition to registration or rectification of a trade mark.
