Appeal No. 1998-0403
Application No. 08/536,232
The Prior Art
In Figure 1, Okado discloses a bridge type power
converter having high side switching devices 51, 53, and 55
and low side switching devices 42, 44, and 46. Diodes are
electrically coupled in parallel with the high and low side
switching devices.
Opinion
After consideration of the positions and arguments
presented by both the examiner and the appellant, we have
concluded that the rejection should not be sustained.
The examiner states “[i]t would have been obvious to one
having ordinary skill in the art at the time the invention was
made to configure the circuit’s diodes to be physically
adjacent to the switching devices since it was known in the
art that to have diodes coupled in parallel to switching
devices and simply rearranging the physical layout of the
circuit but with the same circuit connections is well within
the abilities of the one of ordinary skill in the art.”
(Answer, page 5). The examiner has given no reason why one of
ordinary skill in the art would have rearranged the structure
of Okado in the manner claimed by appellant. The mere fact
