The Demeter trademark may only be used by enterprises and businesses which have a valid contract with the authorised organisation, or a valid agreement covering membership rights to use the trademark (e.g. producers in a regional working group).
The use of the Biodynamic name on products, or material relating to products that is not linked to one of the above mentioned trademark forms is not allowed.
Every use of the word Demeter, and/or one or more of the registered Demeter trademarks in any form, is seen as usage of the trademark. It is also considered use if the impression has been created in the public domain (i.e. in the eyes of consumers) that the products are Demeter.
