Subject matter not provided for in other groups of this subclass
Definition statement

This place covers:

This group is residual to the whole of the subclass, i.e. it covers subject matter which falls under the scope of G06N and which is not covered by its groups.

Therefore this main group should be rarely used or not used for classification.

Whenever a new computing technology is identified, which is not covered by the other main groups of G06N, it is recommended to create a new subgroup here for that new subject.

{Molecular computers, i.e. using inorganic molecules (using biomolecules G06N 3/002)}
Definition statement

This place covers:

Systems where the computational elements are implemented on the molecular level using inorganic molecules e.g. molecular switches.

Relationships with other classification places

Classification in this group is not expected when computational elements implement quantum computers.
