608.04(b) New Matter by Preliminary Amendment [R-10.2019]
A preliminary amendment present on the filing date of the application (e.g., filed along with the filing of the application) is considered a part of the original disclosure. See MPEP § 714.01(e) and § 602. A preliminary amendment filed after the filing date of the application is not part of the original disclosure of the application. See MPEP § 608.04(a). For applications filed on or after September 21, 2004, the Office will automatically treat any preliminary amendment under 37 CFR 1.115(a)(1) that is present on the filing date of the application as part of the original disclosure. Applicants can avoid the need to file a preliminary amendment by incorporating any desired amendments into the text of the specification, even where the application is a continuation or divisional application of a prior-filed application. Applicants are strongly encouraged to avoid submitting any preliminary amendments so as to minimize the burden on the Office in processing preliminary amendments and reduce delays in processing the application.
