Sierra Leone is a party to the Madrid System for International Registration of trade marks and the Paris Convention for Protection of Industrial Property. It is possible to claim priority under the Paris Convention.
Although Sierra Leone is a signatory to the Madrid System it has not amended its national legislation to give effect to the provisions of the Madrid system and it is therefore questionable whether international registrations designating Sierra Leone are enforceable in Sierra Leone.
Sierra Leone follows a single class filing system in terms of the old British 50 class classification. Registration of service is currently not possible.
Sierra Leone has passed legislation adopting the Nice Classification and providing for the registration of service marks but the legislation is not yet in effect.
The total time from filing to registration is approximately 24 months. Trade mark applications are examined for compliance with formal requirements only and are published in the official gazette after acceptance. Trade marks may be opposed within 3 months from the date of publication.
