fibers.” Id. From these findings, the examiner concludes
that it would have been obvious to one of ordinary skill in
the art to combine the length-to-width aspect ratio as taught

ordinary skill in the art, or the nature of the problem to be
solved. See In re Dembiczak, 175 F.3d 994, 999, 50 USPQ2d
1614, 1617 (Fed. Cir. 1999); In re Jones, 958 F.2d 347, 351,
21 USPQ2d 1941, 1943-44 (Fed. Cir. 1992). The showing of the
suggestion, reason or motivation must be clear and particular.
