Failure to Replace Deposit Treats Application as No Deposit Made
Note:
If a deposit is necessary for compliance with 35 U.S.C. 112 and not replaced, the application or patent will be treated as if no deposit was made in any Office proceeding.

37 CFR 1.805(d) sets forth the Office position that the failure to make a replacement deposit in a case pending before the Office, for example a reissue or reexamination proceeding, where a deposit is considered to be necessary to satisfy the requirements of 35 U.S.C. 112, shall cause the application or patent involved to be treated in any Office proceeding as if no deposit were made. The provisions of 37 CFR 1.805(g) indicate that a replacement need not be made where, at the point in time when replacement would otherwise be necessary, access to the necessary biological material was otherwise available. For example, a replacement deposit would not be required under the circumstances where access to the necessary biological material was established through commercial suppliers.
