MPEP 608.01(n): Dependent and Multiple Dependent Claims

Answer in brief

MPEP 608.01(n) covers dependent claims, including multiple dependent claims that refer back to more than one earlier claim in the alternative. A multiple dependent claim may not serve as the basis for another multiple dependent claim, and it must refer to the earlier claims in the alternative only.

What MPEP 608.01(n) covers

Dependent claims must further limit the claim they depend from.

Proper form: "as in claim 1 or 2" or "as in any of claims 1–3" (alternative), not "as in claims 1 and 2" (cumulative).
A multiple dependent claim cannot depend on another multiple dependent claim.
A dependent claim that does not further limit, or that broadens, is rejected under 35 U.S.C. 112(d).
Multiple dependent claims carry an additional fee and count as the number of claims they refer to.

How examiners use it

Improper multiple dependent claims are objected to and not examined on the merits until corrected.

On the patent bar

A favorite fact pattern: decide whether a given claim set contains an improper multiple dependent claim, and how claims are counted for fees.
