Appeal No. 1999-1894
Application 08/847,804
fixed by the trap. When the trap circuit of coil 15 in Dörrie
is tuned to the mean operating wavelength 81 of the highest
frequency band it resonates at "a selected resonant frequency"
of 892.5 MHz. Claim 9 further recites "said first radiating
element having a length of less than a quarter wavelength at
said selected resonant frequency"; thus, the length of the
first radiating element is 81/4. There is a physical
relationship between the resonant frequency of the trap and
the length of the first radiating element. The Examiner errs
in interpreting a "selected resonant frequency" to refer to
something different than the resonant frequency of coil 15,
i.e., to an arbitrary frequency in the band not equal to the
resonant frequency of coil 15.
The Examiner further reasons that a length of less than a
quarter wavelength could happen naturally in a sample of
radiators as a result of tolerances (FR3-4). Appellants
respond that this does not address the claimed radiation
pattern of limitation (2) (Br11). Appellants further argue
that "less than a quarter wavelength" implies a sufficient
departure from a quarter wavelength to be outside a typical
tolerance range of a quarter wavelength design (RBr4).
