Appeal No. 93-3623 Page 15
Application 07/629,690
meets at least the second, alternative, basis for finding
analogousness. In re Deminski, 796 F.2d 436, 442, 230 USPQ 313,
315 (Fed. Cir. 1986). On balance, we find Appellant's conclusory
statement to be unpersuasive.
Teachings of the art as a whole
42. We find that Urdea alone or in view of Hrdina or
Johnson would have taught a person having ordinary skill in the
art the use of peptide-coated discrete particles, preferably made
of silica, as the solid-phase support in a reactor.
D. Longitudinal, hydrophobic membrane
43. Claim 9 (the second contested embodiment, Fig. 10)
requires
at least one strip of hydrophobic membrane bearing a
peptide sample, said strip being positioned in said
cylindrical reaction chamber with its longitudinal axis
substantially parallel to the longitudinal axis of said
chamber.
44. Hood is directed to an apparatus for the sequential
degradation of peptides. (1:11-16.) It teaches the use of a
solid matrix to support the sample. (7:16-26.) The matrix may
be a thin film on the walls of the reaction chamber (Fig. 18A) or
a porous sheet mounted transversely across the chamber (Fig. 6A).
