DEFINITION

Classification: 530/388.25

Binds plasma protein, serum protein, or fibrin (e.g., clotting factor, fibrinolytic factor, complement factor, immunoglobulin, apolipoprotein, 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 plasma protein, serum protein, or with fibrin.

(1) Note. Patents with disclosures to monoclonal antibodies or fragments thereof that bind proteins, including enzymes, that are members of plasma "activation systems"--including the clotting system, the fibrinolytic system, the bradykinin system, and the complement system--are proper for this subclass.

(2) Note. Patents with disclosures to non-anti-idiotypic monoclonal antibodies or fragments thereof that bind immunoglobulins are proper for this subclass, unless the monoclonal antibodies specifically bind lymphocyte-bound immunoglobulins, in which case, they are proper for subclass 388.73.

(3) Note. See Patent Classification Definitions for Class 530, subclasses 380+, for examples of plasma and serum proteins.
