How does an examiner acknowledge receipt of replacement drawing sheets?

Examiners have several methods to acknowledge the receipt of replacement drawing sheets:

1. Using Form Paragraph 6.37
2. Using Form PTOL-324
3. Using the PTOL-326 Office Action Summary

The MPEP 608.02(h) provides the following example of Form Paragraph 6.37:

“The drawings were received on [1]. These drawings are [2].”

In this form paragraph, the examiner would insert the date of receipt in [1] and either ‘acceptable’ or ‘unacceptable’ in [2]. If the drawings are unacceptable, the examiner must provide an explanation, which may include identifying any drawings not entered due to new matter and explaining necessary corrections for resubmission.
