Appeal No. 96-3687
Application 08/008,212
The subject matter relates to a method for the selective
adsorption of PCBs. Claim 9, the only independent claim, is
illustrative of the appealed claims and reads as follows:
9. A method for selective adsorption of PCBs comprising the
steps of:
mixing at least one proteinaceous material with a molar
excess of at least one PCB congener mixture forming a protein/PCB
congener mixture;
drying said protein/PCB congener mixture;
extracting each of said PCB congeners from said dried
protein/PCB congener mixture forming a biosorbent in the form of
an imprinted protein; and
contacting a PCB-containing environment with said imprinted
protein resulting in selective adsorption of said PCBs.
Appellant acknowledges in his brief that claims 9-17 stand
or fall together. Accordingly, we will limit our consideration
to independent claim 9.
The references relied on by the examiner are:
Mosbach 5,110,833 May 5, 1992
Mattingly et al. (Mattingly) 5,145,790 Sep. 8, 1992
Dabulis et al. (Dabulis), "Molecular Imprinting of Proteins and
Other Macromolecules Resulting in New Adsorbents," Biotechnology
and Bioengineering, John Wiley & Sons, Inc., Vol. 39, pages 176-
185 (1992).
Claims 9-17 stand rejected under 35 U.S.C. § 103 as
unpatentable over Mosbach or Dabulis in view of Mattingly. We
will not sustain these rejections. We agree with the appellant
