Appeal No. 1997-0888
Application 08/367,683
We agree with Appellants that Dvorzsak does not teach
using a double template to locate a single acquisition target.
A "template" is defined as an "overlay" and, therefore, a
double template to locate a single acquisition target requires
the two halves of the template pattern to be fixed with
respect to each other to overlay the target. For example, in
the example in the specification, the two templates are a
constant 10 rows apart (specification, page 14). Dvorzsak
determines the centroids of the positioning indicia 14 and 16
and identifies markable locations 12 relative to the
determined centroids. Because the document may be skewed at
an angle, the signatures 26 and 28 in Dvorzsak are a variable
distance apart depending on how much the coded document 10 is
rotated. Thus, the system first finds the centroid of one
pattern and then finds the centroid of the other pattern and
so uses two distinct single templates to locate two distinct
acquisition targets. That is, the two signatures 26 and 28
are not overlaid over the coded document 10 as a template, but
are overlaid separately over patterns 14 and 16, respectively.
The Examiner applies Ghazizadeh for the limitation of a
double template comprising two identical halves, as recited in
