811 Time for Making Requirement - 800 Restriction in Applications Filed Under 35 U.S.C. 111; Double Patenting
811 Time for Making Requirement
37 CFR 1.142(a), second sentence states: "[i]f the distinctness and independence of the invention be clear, such requirement will be made before any action upon the merits; however, it may be made at any time before final action in the case at the discretion of the examiner." This means the examiner should make a proper requirement as early as possible in the prosecution, in the first action if possible, otherwise, as soon as the need for a proper requirement develops.
Before making a restriction requirement after the first action on the merits, the examiner will consider whether there will be a serious burden if restriction is not required.
