Application No. 08/852,681
§ 102(e) as being anticipated by Zurbuchen '251.
A claim is anticipated only if each and every element as
set forth in the claim is found, either expressly or
inherently described, in a single prior art reference.
Verdegaal Bros. Inc. v. Union Oil Co., 814 F.2d 628, 631, 2
USPQ2d 1051, 1053 (Fed. Cir.), cert. denied, 484 U.S. 827
(1987). The law of anticipation does not require that the
reference teach what the appellants are claiming, but only
that the claims on appeal "read on" something disclosed in the
reference (see Kalman v. Kimberly-Clark Corp., 713 F.2d 760,
772, 218 USPQ 781, 789 (Fed. Cir. 1983), cert. denied, 465
U.S. 1026 (1984)).

glass-fiber-reinforced plastic material with box-type
ratcheting inserts molded at opposite ends of the body. The
body includes layers of random discontinuous
glass-fiber-reinforced plastic material and a band of
