Examiner Procedures for Addressing Deposit Issues
Note:
The examiner must follow specific procedures to address deposit issues, with the initial burden on the Office to establish the necessity of access to biological material.

37 CFR 1.809 sets forth procedures that will be used by the examiner to address a deposit issue. The burden is initially on the Office to establish that access to a biological material is necessary for the satisfaction of the statutory requirements for patentability under 35 U.S.C. 112. Once the Office has met this burden, the burden shifts to the applicant or patent owner to demonstrate that access to such biological material either is not necessary, or is already available, or that a deposit of such material will be made in accordance with these regulations.

Examiner Must Determine If Deposit Is Needed and Acceptable for Patent Purposes
Note:
The examiner must decide if a deposit is required in each patent application, reissue application, or reexamination proceeding, and whether any existing deposit meets the necessary criteria.

(a) The examiner shall determine pursuant to § 1.104 in each application for patent, application for reissue patent or reexamination proceeding if a deposit is needed, and if needed, if a deposit actually made is acceptable for patent purposes. If a deposit is needed and has not been made or replaced or supplemented in accordance with these regulations, the examiner, where appropriate, shall reject the affected claims under the appropriate provision of 35 U.S.C. 112, explaining why a deposit is needed and/or why a deposit actually made cannot be accepted.
