DEFINITION

Classification: 435/337

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

(under subclass 332) Subject matter involving an animal cell which produces 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 cells producing monoclonal antibodies or fragments thereof that bind proteins, including enzymes, that are members of plasma "activation systems", such as the clotting system, the fibrinolytic system, the bradykinin system, and the complement system, are proper for this subclass.

(2) Note. Patents with disclosures to cells producing nonanti-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 343.1.

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