Appeal No. 1997-4025
Application 08/340,958
Yoshida’s threshold value is obtained by reducing a
highest input signal (col. 3, line 67 - col. 4, line 3; col.
4, lines 19-29). Yoshida does not determine a minimum
exposure level, based upon the number and position of ON
defects, to be added to all exposure level values as recited
in appellants’ claim 1.
The examiner has not pointed out where the applied
references disclose or would have fairly suggested, to one of
ordinary skill in the art, determining a minimum exposure
level, based upon the number and position of ON defects, and
adding the minimum exposure level to all of a latent image as
required by appellants’ claim 1. Consequently, the examiner
has not carried his burden of establishing a prima facie case
of obviousness of the method in appellants’ claim 1. The
examiner’s rejections, therefore, are reversed.
DECISION
The rejections of claim 1 under 35 U.S.C. § 103 over
Tokuhara in view of Henley, Mochizuki, Endo, Yoshida and
Florence, and over Tokuhara in view of Henley, Noguchi, Endo,
Yoshida and Florence, are reversed.
