Appeal No. 1998-0871
Application No. 08/406,301
We consider Dunlap to fairly suggest to one of ordinary skill in the art the use of a tuner in a
VCR. We agree with the examiner that in the television art, the use of a TV tuner was a
well- known and a common input source to a VCR and that Lim is capable of displaying any
video input signal (col. 16, lines 32-37). In addition, we agree with the examiner that the selection of
video input signals in a VCR by a switching means is fairly taught by Dunlap. We are not persuaded by
appellants’ assertions that (brief, page 6) it would not have been obvious to one of ordinary skill in the
art to include the switching circuit of Dunlap into Lim so that more input selections can be provided to
the viewer because there would have been no motivation to augment the functions of Lim in that
particular direction, and that to piggy-back the tuner
of Dunlap onto the camcorder of Lim would have been beyond the farthest "imaginings"
[sic: imagination] of one of ordinary skill in the art. As we stated, supra, Lim teaches the
use of switching means (55a and 55b) for connecting the VCR (53 and 54) and camera (52) to
the projector and Dunlap discloses a VCR system in which a VCR (12) has multiple inputs including
both a TV tuner (20), for receiving signals from an antenna (fig. 2), and a camera (24); both of which
connect to VCR (12) and which may be displayed on a video output monitor by a switch (col. 2, lines
41-62). In light of the teachings of Dunlap, one of ordinary skill in the art would have a suggestion to
add a tuner and switching means to the system of Lim in order to increase the functionality of Lim’s
