determining a disposition of the starting vertex relative to said predetermined coordinate axis;
determining the polygon is a simple convex polygon in response to the number of direction
changes being less than or equal to two if the starting vertex is disposed between two other vertices
relative to said predetermined coordinate axis and determining the polygon is a simple convex polygon
in response to the number of direction changes being equal to one if the starting vertex is not disposed
between two other vertices relative to said predetermined coordinate axis; and
using alternate function means to display the polygon in the computer system in response to the
step of determining whether the polygon is a simple convex polygon.

Beauregard et al. [Beauregard]4,962,468 Oct. 9, 1990
Claims 1, 6-8 and 13-23 stand rejected under 35 U.S.C. 103 as unpatentable over Beauregard.1
Reference is made to the briefs and answer for the respective positions of appellants and the
examiner.

comments of appellants and the examiner in the briefs and answer, respectively, it is clear that the
rejection of these claims is appealed by appellants and that claims 22 and 23 stand rejected under 35
U.S.C. 103 along with the rest of the claims and we will treat them as such.
