Replacement Deposit Cannot Exceed Original Deposit Standards
Note:
A replacement deposit during the pendency of a patent application cannot be held to a higher standard than an original deposit, subject to conditions.

An applicant for patent may make a replacement deposit during the pendency of the application for any reason. The provisions of 37 CFR 1.805(f) recognize that since an original deposit may be made during the pendency of the application subject to the conditions of 37 CFR 1.809, a replacement deposit logically cannot be held to any higher standard or any further requirements.

Presumption of Identity Between Replacement and Original Deposits
Note:
The Office assumes the replacement deposit matches the original unless contrary evidence is presented.

37 CFR 1.805(e) indicates that the Office will apply a rebuttable presumption of identity between the replacement deposit and an original deposit where a patent making reference to the deposit is relied on during any Office proceeding. This means that where a replacement deposit is permitted and made, the examiner will assume that the same material as described in the patent is accessible from the identified depository unless evidence to the contrary comes to the attention of the Office.

An applicant for patent may make a replacement deposit during the pendency of the application for any reason.
