Appeal No. 98-2357
Application 08/772,336
diameter of Tugwood's coil is larger than the width of the
strap, the strap can obviously be pulled through the coil, it
is well settled that in order to establish a prima facie case
of obviousness the prior art teachings must be sufficient to
suggest to one of ordinary skill in the art making the
modification needed to arrive at the claimed invention. See,
e.g., In re Lalu, 747 F.2d 703, 705, 223 USPQ 1257, 1258 (Fed.
Cir. 1984). Here, there is no such suggestion to make the
inner diameter of Tugwood's coil larger than the width of the
strap.
With respect to claim 9, we have carefully reviewed the
teachings of Staude but find nothing therein which would
overcome the deficiencies of Tugwood and Cook that we have
noted above.
