Depositing patent cultures

We deposit patent cultures for over 30 years in accordance with the rules of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure.

The Czech Collection of Microorganisms has the status of an International Depositary Authority for patent cultures deposited under the Budapest Treaty, which was granted to the CCM by the World Intellectual Property Office (WIPO) in Geneva in 1992.

The CCM accepts the following microorganisms for patent deposit:

1. Bacteria
2. Fungi
3. Yeasts

We only accept species of microorganisms that can be cultivated on commonly used culture media under common conditions and can be stored by lyophilization (another method of storage is possible only upon agreement with the CCM) and belong to risk group 1 or 2 according to the WHO.


Patent cultures are maintained in the form of lyophilized ampoules and stored in liquid nitrogen at the same time.

How to proceed?

Contact the CCM staff ( before sending cultures of microorganisms for deposition. Upon agreement, you will be requested to fill in the appropriate forms, which you will send together with the culture to our address.
