It sometimes occurs that the drawings used for publication of the application are not those originally filed but are subsequently filed drawings, because the latter are more suitable for reproduction (for drawings filed under Rule 56, see A-II, 5 and sub-sections). In this case, the formalities officer in the Receiving Section will check that the subsequently filed drawings are identical to the originals.
However, the ultimate responsibility for ensuring that the subsequently filed drawings do not contain new technical information, which would conflict with Art. 123(2), rests with the Examining Division.
If the examiner considers that these drawings conflict with Art. 123(2), he should require the applicant to submit other drawings which correspond exactly in substance to the drawings originally filed.
It should be noted that it will not normally be possible under Art. 123(2) to add completely new drawings to an application, since in most cases a new drawing cannot be unambiguously derivable from the mere text of the description. For the same reasons amendments to drawings should be carefully checked for compliance with Art. 123(2).
