Sufficiency of disclosure and Rule 56

Under Rule 56, missing parts may be withdrawn in order to maintain the original filing date, and these parts are then deemed to be no longer part of the application (see also A‑II, 5.4.2 and 5.5, C‑III, 1, and H‑IV, 2.3.2).

In this case, the examiner must carefully evaluate whether the invention is still sufficiently disclosed without relying on the technical information contained in the withdrawn missing parts. Should the examiner reach the conclusion that the requirements of Art. 83 are not satisfied, a corresponding objection is raised. Ultimately, the application may be refused for lack of sufficient disclosure (see F‑III, 3 to 5).
