The Office action making the restriction requirement final also ordinarily includes an action on the merits of the claims of the elected invention. See 37 CFR 1.143. In those applications wherein a requirement for restriction is made via telephone and applicant makes an oral election of a single invention, the written record of the restriction requirement will be accompanied by a complete action on the merits of the elected claims. See MPEP § 812.01. The restriction requirement should be made final as soon as reasonably possible. If the election is made with traverse, it is proper to make the restriction requirement final after consideration of the reasons for traversal. See MPEP § 821.01.
