Appeal No. 1998-0988 Page 4
Application No. 08/268,861
Anticipation is established only when a single prior art
reference discloses, expressly or under the principles of
inherency, each and every element of a claimed invention as
well as disclosing structure which is capable of performing the
recited functional limitations. RCA Corp. v. Applied Digital
Data Sys., Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed.
Cir.); cert. dismissed, 468 U.S. 1228 (1984); W.L. Gore and
Assoc. Inc. v. Garlock, Inc., 721 F.2d 1540, 1554, 220 USPQ
303, 313 (Fed. Cir. 1983), cert. denied, 469 U.S. 851 (1984).
At pages 4-5 of the answer, the examiner applies Stefansky
to the elements of claim 1 and, up until the portion of claim 1
reciting “an actuator unlocking apparatus including:,” we agree
with the examiner’s analysis. Claim 1 requires that the
actuator unlocking apparatus include the supply of a
predetermined drive current and a second predetermined drive
current such that the currents are in opposite directions and
the second drive current is selected to stop motion caused by
the first drive current so that the actuator is stopped within
the data zone of the disk storage medium.
