DEFINITION

Classification: 530/391.9

Conjugated via a specifically-identified linking group, coupling agent, or conjugation agent:

(under subclass 391.7) Subject matter involving a monoclonal or polyclonal antibody or immunoglobulin or fragment thereof that is conjugated via a linking group, coupling agent, or conjugation agent that is specifically identified in the claims by name or chemical structure.

(1) Note. Claim language such as "an antibody covalently bonded to a toxin" or "an antibody bound covalently to a toxin" is not intended for this subclass, but is proper for subclass 391.7. Claim language such as "an antibody bound by a disulphide bond to a toxin" or "an antibody bound by an amide bond to a toxin" is proper for this subclass because it describes the type of linkage between the antibody and the substance to which it is linked.
