How are minor drawing corrections handled during patent prosecution?

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.

Minor drawing corrections during patent prosecution are typically handled as follows:

• The examiner may not object to or require correction of minor drawing informalities.
• These minor issues can be pointed out to the applicant in an Office action or interview.
• The applicant can choose to correct these minor issues before allowance.

As stated in MPEP 608.02(p): “Minor drawing corrections will not be objected to by the examiner or required to be corrected by the applicant.”
