CD Laboratories and JR Centres can be established for all topics for which companies have a need for research. The funding programmes of the CDG do not impose any guidelines or restrictions on the themes. Nevertheless, a certain cluster of themes has developed over the years. Close collaboration of research units within a cluster is encouraged by the CDG but not demanded. Competition considerations of the respective commercial partners also play a role in this.
The research topics can be allocated to any of seven clusters.
