6. Prohibited matter 

The provisions on the omission of prohibited matter within the meaning of Rule 48(1)(a) (see A‑III, 8.1 and F‑II, 7.2) also apply to drawings.

Statements or other matter of the type referred to in Rule 48(1)(c) (see F‑II, 7.4) that 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. Doing so introduces matter that is clearly irrelevant or unnecessary, which is expressly prohibited by Rule 48.
