DEFINITION

Classification: 530/389.3

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

(under subclass 389.1) Subject matter involving a polyclonal antibody or immunoglobulin 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 polyclonal antibodies or immunoglobulins 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 nonanti-idiotypic polyclonal antibodies or fragments thereof that bind immunoglobulins are proper for this subclass, unless the antibodies specifically bind lymphocyte-bound immunoglobulins, in which case the patents are proper for subclass 389.6.

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