Appeal No. 2003-1046
Application 09/100,934
embodiment utilizing a 7-digit integer data file 24 which has a
YYYYDDD format. As shown in figure 6, May 2, 1998 shown in the
YYYYDDD format is 2000122. See page 8 of the specification.
Referring to figure 5, the procedure performed when adding days
to a certain date is illustrated. In step S3, the system
determines whether the last three integers in the file is in
excess of 365 or 366 in the event of a leap year. In such case,
the system adds 635 to the number, as shown in step S4. See
page 7 of Appellant’s specification. In the case of subtracting
days from a date, a similar procedure is used. See page 8 of
Appellant’s specification.
Independent claims 5 and 6 present in the application are
reproduced as follows:
