Appeal No. 96-3618
Application 08/004,598
is clearly identified. A cordless telephone meets the
definition of a "portable wireless telephone instrument."
Appellant argues that the Examiner has failed to provide
any explanation why one of ordinary skill in the art would
have been motivated to modify Hong and "a skilled artisan
would have to see a resulting benefit whose value would
clearly outweigh all the obvious drawbacks associated with so
modifying Hong, drawbacks such as: increased size, weight,
power drain, structural and functional complexities, cost,
spectrum requirements, etc." (3dRBr14). One skilled in the
art would have been motivated to modify Hong to achieve the
benefits of a telephone set that could also operate with a
cellular system, which benefits are evident from Gillig or
Kinoshita. One skilled in the art would also have been
motivated to modify either Gillig or Kinoshita to have
inductive recharging to provide more reliable charging as
taught in Hong. The fact that the modification may require
tradeoffs or have disadvantages evident to one of ordinary
skill in the art does not teach away from the modification
itself.
