Can an amendment after allowance introduce new matter under 37 CFR 1.312?

No, amendments after allowance under 37 CFR 1.312 cannot introduce new matter. As stated in MPEP 714.16: ‘No amendment may introduce new matter into the disclosure of an application after the filing date of the application.’ This rule applies to all amendments, including those after allowance. Amendments after allowance are typically limited to correcting formal matters or typographical errors. Any attempt to introduce new subject matter would be rejected and could potentially delay the issuance of the patent.
