806.02(d) Abandonment of Multiple-Basis Applications
If an applicant fails to respond to an Office action or notice of allowance pertaining to only one basis of a multiple-basis application, the failure to respond will result in abandonment of the entire application, unless the applicant files a request to divide under 37 C.F.R. §2.87 and notifies the examining attorney that the request has been filed. See TMEP §§1110–1110.11(a) regarding requests to divide applications. If the failure to respond was unintentional, the applicant may file a petition to revive. See TMEP §§1714–1714.01(g) regarding petitions to revive.
