pattern of void areas, including an objective of providing a
durable, nonwoven fabric characterized by conformability to
wiping surfaces (Abstract; col. 2, ll. 23-27; and col. 4, ll. 55-58);
(2) Greenway discloses that the art has recognized that fiber
orientation within nonwoven web materials employed in fluid
entangling processes correlates to physical properties; and the
invention is directed to a fluid entangling process which obtains a
higher degree of fiber entanglement with consequent improved
fabric texture and tensile characteristics (col. 1, ll. 49-52; and col.
2, ll. 9-13);
(3) Greenway discloses that the entangling member is formed from a
plate including a plurality of generally circular apertures, with
baffle members having a radiused curvature which define
apertures having a “frusto-conical” configuration, thus resulting in
a textile-like fabric pattern in which an array of dense nodes are
connected by a diamond shaped pattern of interstitial fibers (col. 2,
ll. 52-60; col. 3, ll. 3-13; see Figs. 4D, 5A, and 5B, with
accompanying text at col. 6, ll. 12-23);
(4) Greenway exemplifies the use of square and frusto-conical
entangling members (see Figs. 6A and 6B; col. 7, ll. 1-4), while
teaching that “other geometric configurations … may be
employed” (col. 13, ll. 12-16);
(5) Appellants teach that the Average Height Differential is the height
of the raised regions above the recessed regions, while the channel
