being unpatentable over Anderson in view of Philips and
Johnson.
Reference is made to the brief and the answer for the
respective positions of the appellants and the examiner.
OPINION
The obviousness rejection of claims 1, 10 and 11 is
sustained, and the obviousness rejection of claims 2 through
7, 12, 13, 15 through 17, 19 through 25, 28 and 30 is
reversed.
Anderson discloses a high frequency electrodeless
fluorescent lamp (Figure 1) with a ferrite core for coupling
operating power to a light-emitting element in the lamp
(column 2, lines 5 through 7). Anderson states that “[o]ne of
the most important of the criteria in constructing lights in
accord with the present invention is that the ferrite rod be
chosen of a material which, at the operating frequency, has a
relatively low loss so as to transmit a maximum proportion of
power input thereto to the fluorescent envelope . . . .”
(column 4, lines 4 through 9). Since “heating losses with
the ferrite” are important to Anderson, he notes that “the
choice of an ideal ferrite for a particular lamp and for a
