1.1 Technical drawings 

All types of technical drawings are considered drawings within the meaning of the EPC; these include, for instance, perspectives, exploded views, sections and cross-sections, details on a different scale, etc. Drawings also cover "flow sheets and diagrams", which include functional diagrams and graphic representations of a given phenomenon expressing the relationship between two or more magnitudes.

Other graphic forms of presentation – chemical and mathematical formulae and tables – may also be included in the description, claims or abstract but are not subject to the same requirements as drawings (see Art. 2(8) of the decision of the President of the EPO dated 25 November 2022). These are dealt with in A‑IX, 11. If they are nevertheless submitted as drawings, they are subject to the same requirements as drawings.
