Certificate of Deposit

Two copies of the Certificate of deposit is provided to the depositor after the material is tested and found to be viable. A patent deposit number is assigned at this time. The deposit date is the date ATCC receives viable material and its associated completed deposit form, following authorization of shipment from ATCC.

  • If the material is found nonviable, a deposit date is not issued, and no patent deposit number is assigned. For nonviable material, ATCC provides a Certificate of Nonviability (form BP/9).
