Appeal No. 2000-0953 Page 4
Application No. 08/288,418
We will not sustain the rejection of claims 19 and 20
under 35 U.S.C. § 102(b).
To support a rejection of a claim under 35 U.S.C. §
102(b), it must be shown that each element of the claim is
found, either expressly described or under principles of
inherency, in a single prior art reference. See Kalman v.
Kimberly-Clark Corp., 713 F.2d 760, 772, 218 USPQ 781, 789
(Fed. Cir. 1983), cert. denied, 465 U.S. 1026 (1984).
Claims 19 and 20 read as follows:
19. A method of varying the scattering signature of
an antenna having at least one radiating element
fabricated at least in part from high temperature
superconducting material, comprising selectably varying
the temperature of at least a portion of the radiating
element of the antenna about the critical temperature of
said superconducting material to selectably vary the
resistance of said portion of said radiating element and
hence the overall pattern of energy emanating from said
antenna.
20. A method of varying the scattering signature of
an antenna having at least one antenna radiating element
fabricated at least in part from high temperature
superconducting material, said antenna being mounted on a
host platform, to enable said antenna to blend in with
the material of the host platform, comprising selectably
varying the temperature of at least a portion of the
antenna radiating element about the critical temperature
