Appeal No. 98-2792
Application 08/516,257
portion (30) of which is a semi-permeable membrane that is
permeable to the analyte (e.g., glucose). Receptor material
(35, e.g., Con-A) is disposed within the chamber and, more
particularly, is coated on the inner wall of the portion (30)
thereof. The receptor material is capable of chemically
interacting with the analyte. As can be seen in Figure 5b,
light (40) entering the chamber (28) will not be blocked from
impinging on the analyte or receptor material by a chamber
dividing wall restricting passage of said light. Thus, we
conclude that appellant’s claims 15 and 16 on appeal are
readable on the sensor unit of Schultz (Figures 5a, 5b) and
that the subject matter of appellant’s claims 15 and 16 is
therefore anticipated by Schultz.
Appellant’s argument (brief, page 6) that Schultz
does not disclose a sensing unit which is adapted for use with
a remote detection means, because the optical fiber (32) in
Schultz is physically part of and cooperates in defining the
chamber (28), is not persuasive. The sensing unit (26) of
