What is Form Paragraph 13.01 used for in patent examination?

Form Paragraph 13.01 is used by patent examiners to require a rewritten specification when interlineations, cancellations, or amendments could lead to confusion. According to MPEP 1302.02:

“Form paragraph 13.01 should be used when making such a requirement.”

The form paragraph typically states:

“The interlineations or cancellations made in the specification or amendments to the claims could lead to confusion and mistake during the issue and printing processes. Accordingly, the portion of the specification or claims as identified below is required to be rewritten before passing the case to issue. See 37 CFR 1.125 and MPEP § 608.01(q).”

This standardized language helps examiners communicate the need for a rewritten specification efficiently.
