Sudan 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 Sudan 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 Sudan are enforceable in Sudan.
Sudan follows a single class filing system and recognises both goods and service classes in terms of the 9th edition of the Nice Classification.
The total time from filing to registration is approximately 24 months. Trade mark applications are examined for compliance with formal and substantive requirements and are published in the official gazette after acceptance. Trade marks may be opposed within 8 months from the date of publication.
