Advertisement of application
18.  When an application for registration of a trade mark has been accepted, whether absolutely or subject to conditions or limitations, the Registrar shall as soon as possible after its acceptance cause the application as accepted to be advertised in the prescribed manner. The advertisement shall set forth all conditions and limitations subject to which the application has been accepted:
     Provided that the Registrar may cause an application for registration of a trade mark to be advertised before acceptance if it is made under section 10(1)(e) or in any other case where it appears to him that it is expedient by reason of any exceptional circumstances to do so, and where an application has been so advertised the Registrar may, if he thinks fit, advertise it again when it has been accepted but shall not be bound to do so.
