No Deposit During Pendency Bars Certificate of Correction
Note:
A patent cannot be corrected if no deposit was made before or during the application's pendency.

A request for a certificate of correction of a patent under 37 CFR 1.805(b) and 37 CFR 1.805(c) will not be granted where no original deposit was made before or during the pendency of the application which matured into the patent. A patent defective because of lack of a necessary deposit is necessarily fatally defective for failure to comply with the first paragraph of 35 U.S.C. 112. Reissue is not available in such cases. See In re Hay, 534 F.2d 917, 189 USPQ 790 (CCPA 1976).

Certificate of Correction Required for Replacement or Supplemental Deposits
Note:
A certificate of correction under 37 CFR 1.323 must be requested and meet the terms of 37 CFR 1.805(b) and (c) before a replacement or supplemental deposit can be accepted.

A replacement or supplemental deposit made in connection with a patent, whether or not made during the pendency of an application for reissue patent or a reexamination proceeding or both, shall not be accepted unless a certificate of correction under 37 CFR 1.323 is requested which meets the terms of 37 CFR 1.805(b) and 37 CFR 1.805(c) for replacement or supplemental deposits.
