Appeal No. 1999-0084
Application No. 08/448,854
Mack for the handover method of Menich et al. The
Appellant [sic] respectfully submits that the
teaching of Mack is completely unrelated to a
handover process and can not be combined with the
teaching of the Menich et al [reference], which
relates to the handover process. Therefore, there
is no valid basis for combining the teaching of Mack
with that of Menich et al. and such combination
clearly amounts to improper use of hindsight.
We agree with appellants’ argument that the skilled
artisan would not have looked to the stationary remote station
teachings of Mack to modify the mobile station handover
teachings of Menich. Turning to Toriyama, we likewise agree
with the appellants’ argument (brief, page 8) that
“[e]xpanding the coverage area of a cordless phone has no
relevance to enlarging the overlapping regions of a cellular
system for a handover process.”
