corrected for timing synchronization errors (col. 31, lines 65-
68).
We find Appellants’ arguments distinguishing the claimed
using a coarse position in a GPS to determine an accurate
position over Cisneros’ clock error correction to be persuasive.
As discussed above, what the Examiner characterizes in Cisneros
as the use of the coarse position is actually the correction of
the synchronization of the GPS clock with that of the UBS.
Although the clock error correction signal improves the GPS
accuracy, it is not a coarse position signal that may be used by
the GPS for accurate position of the mobile terminal.
Additionally, the Examiner neither points to any specific portion
of Cicneros for obtaining a coarse position that may be used by
GPS for accurate positioning, nor do we find that the clock error
correction signal of Cicneros reads on the recited features.
We also note that although the Examiner apparently expects
that this panel rely on additional portions of the reference to
buttress the Examiner’s position (answer, page 19), we remind the
Examiner that as a general principle, the initial burden of
establishing reasons for unpatentability rests on the examiner.
