Appeal No. 96-1990
Application 07/536,910
are performed to simulate different relative sizes in the
subpatterns of a character (Leung, pp. 38-39). Both shearing and
warping operations are performed no matter what the model symbols
are. Leung, alone, would not have reasonably suggested the
inputting of user selected defect class parameters and the
generation of defective pixel representations according to the
defect classes specified by the inputted defect class parameters.
We agree with the appellant (Br. at 10) that the claimed
invention permits the user to define his or her own defect model
and to generate defective pixel representations corresponding to
the defined model by selecting from among a number of defect
classes. Leung, on the other hand, does not disclose or suggest
user-selection of particular defect classes to tailor or
customize the output pixel representations to the desired or
preferred defect classes.
For the foregoing reasons, we reverse the rejection of
claims 6-34, 36-38 and 40-41 under 35 U.S.C. § 103 as being
unpatentable over Leung.
