How do I deposit?

How do I deposit biological material?

The first step in depositing biological material for patent purposes is to contact the ATCC Patent Depository to initiate completion of one of the forms below:

  • Budapest Treaty Deposit Form (BP/1) must be completed for deposits to meet the requirements of The Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure.
  • Non-Budapest Treaty Deposit Form (34) must be completed for all other patent deposits. It is not necessary to complete Form 34 if you complete the BP/1 form. If both forms are completed, the BP/1 form supersedes Form 34.

Complete identification of patent deposit material is required by the depositor for each deposited item to ensure that ATCC is aware of all characteristics that may impact regulatory compliance in their handling, storage, and distribution. This information must be included on the BP/1 form or Form 34, or appended as necessary. There is an additional information form for depositing a virus.

ATCC will review the forms to ensure that all required documentation and any necessary regulatory permits are in place. If you do not contact ATCC prior to shipping your biological materials, there will be delays in processing your patent deposit, or return or destruction of your materials to comply with regulatory restrictions. Following review of the BP/1 form or Form 34, ATCC will provide further instructions for shipment and depositing.
