What happens if patent drawings don’t comply with MPEP requirements?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

If patent drawings do not comply with the requirements set forth in MPEP 608.02(d), the following process occurs:

1. The examiner will require additional illustration
2. A notice will be sent to the applicant
3. The applicant will have at least two months from the date of the notice to submit corrected drawings
4. Corrections must comply with 37 CFR 1.81(d)

According to the MPEP: Where the drawings in a nonprovisional application do not comply with the requirements of paragraphs (a) and (b) of this section, the examiner shall require such additional illustration within a time period of not less than two months from the date of the sending of a notice thereof. This process ensures that all necessary details are properly illustrated before the application can proceed.
