§113. Drawings

The applicant shall furnish a drawing where necessary for the understanding of the subject matter sought to be patented.

Drawings submitted after the filing date of the application may not be used (i) to overcome any insufficiency of the specification due to lack of an enabling disclosure or otherwise inadequate disclosure therein, or (ii) to supplement the original disclosure thereof for the purpose of interpretation of the scope of any claim.
