Cumulative Claiming Not Permitted
Note:
A claim cannot refer to multiple preceding claims in the alternative.

35 U.S.C. 112(e), authorizes multiple dependent claims in applications as long as they are in the alternative form (e.g., “A machine according to claims 3 or 4, further comprising —”). Cumulative claiming (e.g., “A machine according to claims 3 and 4, further comprising —”) is not permitted. A multiple dependent claim may refer in the alternative to only one set of claims. A claim such as “A device as in claims 1, 2, 3, or 4, made by a process of claims 5, 6, 7, or 8” is improper. 35 U.S.C. 112 allows reference to only a particular claim. Furthermore, a multiple dependent claim may not serve as a basis for any other multiple dependent claim, either directly or indirectly. These limitations help to avoid undue confusion in determining how many prior claims are actually referred to in a multiple dependent claim.

Limitations of Multiple Dependent Claims Must Be Considered Separately
Note:
Each limitation in a multiple dependent claim must be considered separately, not as part of all referenced claims.

35 U.S.C. 112 indicates that the limitations or elements of each claim incorporated by reference into a multiple dependent claim must be considered separately. Thus, a multiple dependent claim, as such, does not contain all the limitations of all the alternative claims to which it refers, but rather contains in any one embodiment only those limitations of the particular claim referred to for the embodiment under consideration. Hence, a multiple dependent claim must be considered in the same manner as a plurality of single dependent claims. See Nested Bean, Inc. v. Big Beings Pty Ltd., IPR2020-01234, Paper 42 (Feb. 24, 2023).

Claim 11 — Claim 11 is a dependent claim which refers to two claims in the conjunctive (“1” and “9”) rather than in the alternative (“1” or “9”). This form is improper under 35 U.S.C. 112 and 37 CFR 1.75(c). Accordingly, since claim 11 is improper, an encircled number “1” is placed in the “Dep.” column opposite Claim 11.

Dependent Claims Must Reference Previous Claim
Note:
Examiners must ensure dependent claims reference a previous claim, add further limitations, and include all prior claim limitations.

When examining a dependent claim, the examiner should determine whether the claim complies with 35 U.S.C. 112(d), which requires that dependent claims contain a reference to a previous claim in the same application, specify a further limitation of the subject matter claimed, and include all the limitations of the previous claim. If the dependent claim does not comply with the requirements of 35 U.S.C. 112(d), the examiner should reject the dependent claim under 35 U.S.C. 112(d) as unpatentable rather than objecting to the claim. See Pfizer, Inc. v. Ranbaxy Labs., Ltd., 457 F.3d 1284, 1291-92, 79 USPQ2d 1583, 1589-90 (Fed. Cir. 2006) (holding a dependent claim in a patent invalid for failure to comply with pre-AIA 35 U.S.C. 112, fourth paragraph (now 35 U.S.C. 112(d))). Although the requirements of 35 U.S.C. 112(d) are related to matters of form, non-compliance with 35 U.S.C. 112(d) renders the claim unpatentable just as non-compliance with other paragraphs of 35 U.S.C. 112 would. For example, a dependent claim must be rejected under 35 U.S.C. 112(d) if it omits an element from the claim upon which it depends or it fails to add a limitation to the claim upon which it depends.

Requirement for Compliant Dependent Claims under 112(d)
Note:
A dependent claim must comply with the requirements of 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph to be considered patentable.

2. The U.S. Court of Appeals for the Federal Circuit indicated that although the requirements of pre-AIA 35 U.S.C. 112, 4th paragraph, are related to matters of form, non-compliance with pre-AIA 35 U.S.C. 112, 4th paragraph, renders the claim unpatentable just as non-compliance with other paragraphs of 35 U.S.C. 112 would. See Pfizer, Inc. v. Ranbaxy Labs., Ltd., 457 F.3d 1284, 1291-92, 79 USPQ2d 1583, 1589-90 (Fed. Cir. 2006) (holding a dependent claim in a patent invalid for failure to comply with pre-AIA 35 U.S.C. 112, 4th paragraph). Therefore, if a dependent claim does not comply with the requirements of 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, the dependent claim should be rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as unpatentable rather than objecting to the claim.

Fee Required for New Multiple Dependent Claims
Note:
The amendment adding new multiple dependent claims must be paid before it can be entered.

If a multiple dependent claim (or claims) is added in an amendment without the proper fee, either by adding references to prior claims or by adding a new multiple dependent claim, the amendment should not be entered until the fee has been received. In view of the requirements for multiple dependent claims, no amendment containing new claims or changing the dependency of claims should be entered before checking whether the paid fees cover the costs of the amended claims. The applicant, or the applicant's attorney or agent, should be contacted to pay the additional fee.

Improper Multiple Dependent Claims Require Fee
Note:
If a multiple dependent claim is improper, OPAP indicates it by placing an encircled ‘1’ in the Dep. Claims column and charges only one fee for such claims.

If any multiple dependent claim is improper, OPAP may indicate that fact by placing an encircled numeral “1” in the “Dep. Claims” column of form PTO/SB/07. The fee for any improper multiple dependent claim, whether it is defective for either not being in the alternative form or for being directly or indirectly dependent on a prior multiple dependent claim, will only be one, since only an objection to the form of such a claim will normally be made. This procedure also greatly simplifies the calculation of fees. Any claim depending from an improper multiple dependent claim will also be considered to be improper and be counted as one dependent claim.

The initial determination, for fee purposes, as to whether a claim is dependent must be made by persons other than examiners; it is necessary, at that time, to accept as dependent virtually every claim which refers to another claim, without determining whether there is actually a true dependent relationship. The initial acceptance of a claim as a dependent claim does not, however, preclude a subsequent holding by the examiner that a claim is not a proper dependent claim.

Dependent Claim Must Refer to Previous Claim
Note:
A dependent claim must only refer to a previously set forth claim.

Pursuant to 35 U.S.C. 112 and 37 CFR 1.75(c), a claim in dependent form must refer only to a claim or claims previously set forth. The following procedures are to be followed by examiners when faced with claims which refer to numerically succeeding claims:

Conjunctive Dependent Claims Prohibited
Note:
Claims must not refer to multiple claims in conjunctive form; instead, use the alternative form.

Claim 11 — Claim 11 is a dependent claim which refers to two claims in the conjunctive (“1” and “9”) rather than in the alternative (“1” or “9”). This form is improper under 35 U.S.C. 112 and 37 CFR 1.75(c). Accordingly, since claim 11 is improper, an encircled number “1” is placed in the “Dep.” column opposite Claim 11.

Dependent Claim Must Comply With 112(d)
Note:
A dependent claim must reference the previous claim, add a further limitation, and include all limitations of the previous claim to be patentable.

When examining a dependent claim, the examiner should determine whether the claim complies with 35 U.S.C. 112(d), which requires that dependent claims contain a reference to a previous claim in the same application, specify a further limitation of the subject matter claimed, and include all the limitations of the previous claim. If the dependent claim does not comply with the requirements of 35 U.S.C. 112(d), the examiner should reject the dependent claim under 35 U.S.C. 112(d) as unpatentable rather than objecting to the claim. See Pfizer, Inc. v. Ranbaxy Labs., Ltd., 457 F.3d 1284, 1291-92, 79 USPQ2d 1583, 1589-90 (Fed. Cir. 2006) (holding a dependent claim in a patent invalid for failure to comply with pre-AIA 35 U.S.C. 112, fourth paragraph (now 35 U.S.C. 112(d))). Although the requirements of 35 U.S.C. 112(d) are related to matters of form, non-compliance with 35 U.S.C. 112(d) renders the claim unpatentable just as non-compliance with other paragraphs of 35 U.S.C. 112 would. For example, a dependent claim must be rejected under 35 U.S.C. 112(d) if it omits an element from the claim upon which it depends or it fails to add a limitation to the claim upon which it depends.

Non-Compliance with Pre-AIA 112, 4th Paragraph Renders Claim Unpatentable
Note:
If a dependent claim fails to comply with the requirements of pre-AIA 35 U.S.C. 112, 4th paragraph, it should be rejected as unpatentable rather than objected to.

2. The U.S. Court of Appeals for the Federal Circuit indicated that although the requirements of pre-AIA 35 U.S.C. 112, 4th paragraph, are related to matters of form, non-compliance with pre-AIA 35 U.S.C. 112, 4th paragraph, renders the claim unpatentable just as non-compliance with other paragraphs of 35 U.S.C. 112 would. See Pfizer, Inc. v. Ranbaxy Labs., Ltd., 457 F.3d 1284, 1291-92, 79 USPQ2d 1583, 1589-90 (Fed. Cir. 2006) (holding a dependent claim in a patent invalid for failure to comply with pre-AIA 35 U.S.C. 112, 4th paragraph). Therefore, if a dependent claim does not comply with the requirements of 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, the dependent claim should be rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as unpatentable rather than objecting to the claim.

Multiple Dependent Claims Must Be In Alternative Form
Note:
Claims must be in the alternative form, referring to only one set of claims and not serving as a basis for other multiple dependent claims.

35 U.S.C. 112(e), authorizes multiple dependent claims in applications as long as they are in the alternative form (e.g., “A machine according to claims 3 or 4, further comprising —”). Cumulative claiming (e.g., “A machine according to claims 3 and 4, further comprising —”) is not permitted. A multiple dependent claim may refer in the alternative to only one set of claims. A claim such as “A device as in claims 1, 2, 3, or 4, made by a process of claims 5, 6, 7, or 8” is improper. 35 U.S.C. 112 allows reference to only a particular claim. Furthermore, a multiple dependent claim may not serve as a basis for any other multiple dependent claim, either directly or indirectly. These limitations help to avoid undue confusion in determining how many prior claims are actually referred to in a multiple dependent claim.

Examiner Form Paragraphs

Examiner form paragraphs are standard language that you might see in an Office Action or communication from the USPTO. Examiners have latitude to change the form paragraphs, but you will often see this exact language.

¶ 7.45 ¶ 7.45 Improper Multiple Dependent Claims
¶ 7.36 ¶ 7.36 Statement of Statutory Basis, 35 U.S.C. 112(d) and Pre-AIA 35 U.S.C. 112, Fourth Paragraph
¶ 6.18 ¶ 6.18 Series of Singular Dependent Claims

A series of singular dependent claims is permissible in which a dependent claim refers to a preceding claim which, in turn, refers to another preceding claim.

A claim which depends from a dependent claim should not be separated by any claim which does not also depend from said dependent claim. It should be kept in mind that a dependent claim may refer to any preceding independent claim. In general, applicant’s sequence will not be changed. See MPEP § 608.01(n) .

¶ 7.43 ¶ 7.43 Objection to Claims, Allowable Subject Matter

Claim [1] objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
