USPTO to Clarify Guidance on Written Description of Antibodies

The memorandum points to Amgen for stating that the “newly characterized antigen” test could not stand because it contradicted the quid pro quo of the patent system whereby in order to obtain a patent one must describe an invention (the antibody, not the antigen recognized by the antibody). The memorandum states that in view of Amgen, “adequate written description of a newly characterized antigen alone should not be considered adequate written description of a claimed antibody to that newly characterized antigen, even when preparation of such an antibody is routine and conventional.”
