Application No. 08/979,069
re Mattison, 509 F.2d 563, 565, 184 USPQ 484, 486 (CCPA
1975)).
Here, claims 20 and 21 specify in pertinent part the
following limitations: "zooming from a first bounding
rectangle for the selected block of text at a source location
to a second bounding rectangle for the selected block of text
at the destination location ...." The specification describes
the zooming as follows.
[T]he zoom starts with a bounding rectangle 100
displayed near the source location. Two or more
rectangles are displayed on monitor 12 at a time,
each successive rectangle more closely approaching
the dimensions and final location of bounding
rectangle 104. Figure 4C attempts to illustrate
this idea. The dimensions of intervening rectangle
106 differ slightly from those bounding rectangle
100, just starting to approach those of bounding
rectangle 104. Similarly, the dimensions of
intervening rectangle 108 differ from those of
intervening rectangle 106, approaching more closely
the dimensions of bounding rectangle 104. The zooms
ends with the display of bounding rectangle 104 near
the destination location.
(Spec. at 14-15.) Reading the claims in light of the
specification, the limitations require that zooming begins
with the display of a first bounding rectangle for a selected
block of text at a source location and ends with the display
