The provisions as to the omission of prohibited matter within the meaning of Rule 48(1)(a) (see III, 8.1 and C-II, 7.2) also apply to drawings.

Statements or other matter of the type referred to under Rule 48(1)(c) (see C-II, 7.4) which are likely to appear in drawings are in particular various kinds of advertising, e.g. where the applicant includes in the drawing obvious business or departmental markings or a reference to an industrial design or model, whether registered or not. By doing so, matter would be introduced which is clearly irrelevant or unnecessary, which is expressly prohibited by Rule 48.
