Appeal No. 2000-0672
Application 08/838,027
the stored values disclosed by Drebinger relate to a relative
value delays between two receivers. See Brief, page 3, lines 2-5
and page 4, lines 9-10.
The Examiner, in reference to Drebinger’s Figure 5, argues
that Drebinger teaches a stored correction value (k = tf2 - tf1)
that is a function of tf2 and tf1, which are transit time delays
in the receiving station and in the lines or cables. See Answer,
page 5, lines 2-4. The Examiner argues that the value of k is
associated with a corresponding receiver stage delay since it is
a function of both the transit time delays associated with both
receivers. See Answer, page 5, lines 5-6.
Anticipation requires that each and every element of the
claimed invention be disclosed in a single prior art reference.
See In re King, 801 F.2d 1324, 1326, 231 USPQ 136, 138 (Fed. Cir.
1986) and Lindermann Mashinenfabrik GMBH v. American Hoist &
Derrick Co., 730 F.2d 1452, 1458, 221 USPQ 481, 485 (Fed. Cir.
1984).
We find that Drebinger does not teach the limitation of
storing a “signal delay associated with one or more receiver
stages of the corresponding positioning radio receiver,” as being
claimed by the Appellants. Appellants refer to signal delay
