DEFINITION

Classification: 530/388.22

Binds receptor (e.g., transferrin receptor, Fc receptor, dihydropyridine receptor, IL-2 receptor, etc.):

(under subclass 388.2) Subject matter involving a monoclonal antibody or antigen-binding fragment thereof whose antigen-binding site(s) will combine with a free or micro-organism-associated receptor.

(1) Note. A receptor is a structure integral to a

micro-organism or released into the surrounding milieu that has binding specificity for a particular three-dimensional structural configuration of a molecule or portion thereof.

(2) Note. For the purpose of this subclass, an antibody is not considered a receptor. Patents disclosing non-anti-idiotypic monoclonal antibodies or fragments thereof that bind other immunoglobulins are proper for subclass 388.25, unless the monoclonal antibodies specifically bind lymphocyte-bound immunoglobulins, in which case the patents are proper for subclass 388.73.
