Appeal No. 95-4968
Application 08/074,518
to correspond to the structure that performs the induction field
calculation described in the Appellant's specification.
Our reviewing court has stated in In re Donaldson Co. Inc.,
16 F.3d 1189, 1193, 29 USPQ2d 1845, 1848 (Fed. Cir. 1994) that
the "plain and unambiguous meaning of paragraph six is that one
construing means-plus-function language in a claim must look to
the specification and interpret that language in light of the
corresponding structure, material, or acts described therein, and
equivalents thereof, to the extent that the specification
provides such disclosure." We find that Appellant's Figure 1
discloses the field of induction calculating means as block 2 and
Appellant discloses that field of induction calculating means
calculates the field of induction by the process described on
pages 8 and 9 of the Appellant's specification. In particular,
the field of induction at a point 30, shown in Figure 3, is
calculated based on an analogy to an electric field experienced
at a point (30) resulting from unit charges at a series of other
points (31-37). The points 21-37 of Figure 3, which are the
pixels which form the character to be recognized, are treated as
if they had a unit charge which contributes to a field inducted
at point 30 by all such unit charges. The summation of the
