Patent Deposits

Deposit for the purposes of patent procedure

In 2013, the World Intellectual Property Organization (WIPO) designated the NCMA as an International Depositary Authority (IDA) for the deposit of biological material for the purposes of patent procedure under the Budapest Treaty. Deposits may be any algae (including single-celled microalgae and multicellular algae), aquatic and terrestrial protists, bacteria and archaea, and non-differentiated plant cells.  Please click here for our Business Overview and here for more detail on our Private Collection services (cryopreservation, annual culturing, etc.).

What we accept:

Any algae (including single-celled microalgae and multicellular algae), eukaryotic protists, bacteria, archaea, or viruses from any aquatic environments (including freshwater, brackish, marine, and hyper-saline), plant tissue cultures (terrestrial or aquatic) and seeds, and bacteria and fungi from terrestrial environments.


Requests for Release of Material under Patent Deposit

NCMA keeps all information about patent deposits confidential, and only releases material on the instruction of the depositor or in accordance with the requirements of the patenting process.

Budapest Treaty deposits

Every time a sample of your biological material is released, you will be officially notified of the name and address of the recipient.  Biological material is made available to those entitled to receive them under Rule 11 of the Treaty, i.e.:

  • The patent office(s) with which your application has been filed (11.1).
  • Anyone having depositors specific written authorization to receive a culture (11.2).
  • Anyone making their request on an official form on which the relevant patent office has certified that they are entitled to receive a culture and that the patent office has submitted directly to NCMA (Rule 33 EPC 11.3a).
  • In cases where the Expert Solution (Witness) clause has been requested at the time of application, sample will only be made available to a nominated exert - Rule 32 EPC (11.3a).
  • In certain cases, where a patent has been granted and published (e.g. in the US), no certification is required.  In these circumstances, incontrovertible evidence that the patent has been issued is required.  In these circumstances, incontrovertible evidence that the patent has been issued is required before a sample is released.

An expert witness is 1) any natural person provided that the requester furnished evidence, when filing the request, that the nomination has the approval of the applicant; 2) any natural person recognized as an expert by the President of the EPO.

The nomination of the expert witness must be accompanied by a declaration from the expert vis-a-vis the applicant in which he/she enters into the undertaking given pursuant to Rule 33 EPC until either the date on which the patent expires in all the designated States or, where the application has been refused, withdrawn or deemed to be withdrawn, until the date referred to in Rule 32(1)(b) EPC, the requester being regarded as a third party.
