Appeal No. 1999-0444
Application No. 08/758,655
Again, in our opinion, one of ordinary skill in the art
would have been motivated by these advantages as taught by
Rubbo 494 to set the packer or/and fire the gun of Leutwyler
803, as modified by Ross '860 or Council '046 or Crawford
'642, with an acoustical signal or a pressure signal.
Appellants further argue that the examiner seeks to
combine Leutwyler with the other references without
considering the fact that Leutwyler 803 does not make any
suggestion of how the components of Leutwyler 803 would
operate without an electrical signal received from a wireline
configuration. This argument is not convincing. As is noted
by the examiner, it is well known in the art that when a
coiled tubing is utilized to run an electrically operated
downhole well tool, an electrical cable is provided inside the
coiled tubing so that electrical signals may be sent downhole
to actuate the well tool. Moreover, the secondary reference
to Rubbo ‘494 discussed above clearly shows that it is also
well known in the art to actuate a downhole tool by using a
pressure signal, a physical movement signal or an acoustical
signal or a combination thereof for various advantages as
