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.
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.
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).
