Show the answer and explanation

Answer: A. May 11, 2026, with the missing parts to follow

Answer: May 11, 2026, with the missing parts to follow. Since the Patent Law Treaties Implementation Act, a nonprovisional utility application gets a filing date on the date a specification, with or without claims, is received, along with any drawings required. The Office will send a notice requiring the missing claims, fees and oath or declaration, with surcharges as applicable (37 CFR 1.53(b), (f); MPEP 601.01(a)). Why not the others: - A claim required: claims are no longer needed for a utility filing date. - Fees: fees may be paid later with a surcharge. - The oath date: the oath or declaration can be filed later. - Conversion to a provisional: the application keeps its nonprovisional filing date; no conversion is needed. Rule: A utility nonprovisional's filing date needs a specification (claims optional) and any required drawings. Source: MPEP § 601.01(a) (9th ed., Rev. 01.2024); 35 U.S.C. 111(a); 37 CFR 1.53(b), (f); as at Oct 2026

Common mistake

Applying the pre-2013 rule that a nonprovisional needed a claim for a filing date.
