Generally, the Receiving Section will deal with matter falling under category 1(a) and may have dealt with matter obviously falling within category 1(b), but if any such matter has not been so recognised and has therefore not been omitted from the publication of the application, it is required to be removed during examination of the application together with any other prohibited matter. The applicant is informed of the category under which matter is required to be removed.[Rule 48(2); Rule 48(3); ]
