608.04    New Matter [R-10.2019]

35 U.S.C. 132   Notice of rejection; reexamination.

  • (a) Whenever, on examination, any claim for a patent is rejected, or any objection or requirement made, the Director shall notify the applicant thereof, stating the reasons for such rejection, or objection or requirement, together with such information and references as may be useful in judging of the propriety of continuing the prosecution of his application; and if after receiving such notice, the applicant persists in his claim for a patent, with or without amendment, the application shall be reexamined. No amendment shall introduce new matter into the disclosure of the invention.

*****

37 C.F.R. 1.121   Manner of making amendments in applications.

*****

  • (f) No new matter. No amendment may introduce new matter into the disclosure of an application.

*****

In establishing a disclosure, applicant may rely not only on the specification and drawing as filed but also on the claims present on the filing date of the application if their content justifies it. See MPEP § 608.01(l).

While amendments to the specification and claims involving new matter are ordinarily entered, such matter (i.e., subject matter not present in the specification, claims, or drawings on the application filing date) is required to be canceled from the descriptive portion of the specification, and the claims affected are rejected under 35 U.S.C. 112(a).

When new matter is introduced into the specification, the amendment should be objected to under 35 U.S.C. 132  (35 U.S.C. 251  if a reissue application) and a requirement made to cancel the new matter. The subject matter which is considered to be new matter must be clearly identified by the examiner. If the new matter has been entered into the claims or affects the scope of the claims, the claims affected should be rejected under 35 U.S.C. 112(a)  because the new matter is not described in the application as originally filed.

A "new matter" amendment of the drawing is ordinarily not entered; neither is an additional or substitute sheet containing "new matter" even though provisionally entered by the TC technical support staff. See MPEP § 608.02(h).

The examiner’s holding of new matter may be petitionable or appealable. See MPEP § 608.04(c).

For new matter in reissue application, see MPEP § 1411.02. For new matter in substitute specification, see MPEP § 608.01(q). For new matter in a continuation or divisional application, see MPEP § 211.05.

Note: No amendment is permitted in a provisional application after it receives a filing date.

608.04(a)    Matter Not Present in Specification, Claims, or Drawings on the Application Filing Date [R-10.2019]

Matter not present on the filing date of the application in the specification, claims, or drawings that is added after the application filing is usually new matter. See MPEP §§ 2163.06 and 2163.07 for guidance in determining whether an amendment adds new matter, and for a discussion of the relationship of new matter to 35 U.S.C. 112(a)  or pre-AIA 35 U.S.C. 112, first paragraph. See MPEP § 2163.07(a) to determine whether added characteristics such as chemical or physical properties, a new structural formula or a new use are inherent characteristics that do not introduce new matter.

New matter includes not only the addition of wholly unsupported subject matter, but may also include adding specific percentages or compounds after a broader original disclosure, or even the omission of a step from a method. See In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976) and MPEP § 2163.05 for guidance in determining whether the addition of specific percentages or compounds after a broader original disclosure constitutes new matter.

In the examination of an application following amendment thereof, the examiner must be on the alert to detect new matter. 35 U.S.C. 132(a)  should be employed as a basis for objection to amendments to the abstract, specification, or drawings attempting to add new disclosure to that originally disclosed on filing. If new matter is added to the specification, it should be objected to by using Form Paragraph 7.28.

¶ 7.28    Objection to New Matter Added to Specification

The amendment filed [1] is objected to under 35 U.S.C. 132 (a) because it introduces new matter into the disclosure. 35 U.S.C. 132(a)  states that no amendment shall introduce new matter into the disclosure of the invention. The added material which is not supported by the original disclosure is as follows: [2].

Applicant is required to cancel the new matter in the reply to this Office action.

Examiner Note:

1. This form paragraph is not to be used in reissue applications; use form paragraph 14.22.01 instead.

2. In bracket 2, identify the new matter by page and the line numbers and provide an appropriate explanation of your position. This explanation should address any statement by applicant to support the position that the subject matter is described in the specification as filed. It should further include any unresolved questions which raise a doubt as to the possession of the claimed invention at the time of filing.

3. If new matter is added to the claims, or affects the claims, a rejection under 35 U.S.C. 112(a)  or pre-AIA 35 U.S.C. 112, first paragraph, using form paragraph 7.31.01 should also be made. If new matter is added only to a claim, an objection using this paragraph should not be made, but the claim should be rejected using form paragraph 7.31.01. As to any other appropriate prior art or 35 U.S.C. 112  rejection, the new matter must be considered as part of the claimed subject matter and cannot be ignored.

If the new matter has been entered into the claims or affects the scope of the claims, the claims affected should be rejected under 35 U.S.C. 112(a)  or pre-AIA 35 U.S.C. 112, first paragraph, on the ground that it recites elements without support in the original disclosure. See Waldemar Link, GmbH & Co. v. Osteonics Corp., 32 F.3d 556, 559, 31 USPQ2d 1855, 1857 (Fed. Cir. 1994); Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1560 (Fed. Cir. 1991)(A written-description question often arises when an applicant, after filing a patent application, subsequently adds "new matter" not present in the original application.); In re Rasmussen, 650 F.2d 1212, 211 USPQ 323 (CCPA 1981).

If subject matter capable of illustration is originally claimed and it is not shown in the drawing, the claim is not rejected but applicant is required to add it to the drawing. See MPEP § 608.01(l). Replacement drawings containing new matter should not be entered and the corrections necessary to obtain entry of the drawing(s) should be explained using form paragraph 6.37. See MPEP § 608.02(h).

For completeness of specification, see MPEP § 608.01(p). For trademarks and trade names, see MPEP § 608.01(v).

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.

608.04(c)    Review of Examiner’s Holding of New Matter [R-11.2013]

Where the new matter is confined to amendments to the specification, review of the examiner’s requirement for cancelation is by way of petition. But where the alleged new matter is introduced into or affects the claims, thus necessitating their rejection on this ground, the question becomes an appealable one, and should not be considered on petition even though that new matter has been introduced into the specification also. See also MPEP § 2163.06.
