MPEP GuidanceRecommendedAlways
[mpep-806-04-d-53d254fbff118d844c1261f9]
Generic Claim Must Read on Each View
Note:
A generic claim in an application must cover all illustrated species, but it may define only common elements across the views.

In an application presenting three species illustrated, for example, in Figures 1, 2, and 3, respectively, a generic claim should read on each of these views; but the fact that a claim does so read is not conclusive that it is generic. It may define only an element or subcombination common to the several species.

Generic Claim Requires Same Elements as Species Claims
Note:
A generic claim must include all limitations of the species claims it covers.

In general, a generic claim should require no material element additional to those required by the species claims, and each of the species claims must require all the limitations of the generic claim.

Allowability of Species Claims Based on Generic Claim
Note:
If a generic claim is allowable, claims to additional species that require all its limitations are also allowed if they depend on or include those limitations.

Once a generic claim is allowable, all of the claims drawn to species in addition to the elected species which require all the limitations of the generic claim will ordinarily be allowable over the prior art in view of the allowability of the generic claim, since the additional species will depend thereon or otherwise require all of the limitations thereof. When all or some of the claims directed to one of the species in addition to the elected species do not require all the limitations of the generic claim, see MPEP § 821.04(a).

Species Claims Not Requiring All Generic Limitations
Note:
When claims for species in addition to the elected species do not include all limitations of the generic claim, they are still considered allowable if the generic claim is valid.

Once a generic claim is allowable, all of the claims drawn to species in addition to the elected species which require all the limitations of the generic claim will ordinarily be allowable over the prior art in view of the allowability of the generic claim, since the additional species will depend thereon or otherwise require all of the limitations thereof. When all or some of the claims directed to one of the species in addition to the elected species do not require all the limitations of the generic claim, see MPEP § 821.04(a).
