Appeal No. 96-3101
Application 08/020,570
Appellant’s invention relates to a circuit arrangement
having an array of electrical circuits (21) for forming a
reversible image on a printing form (2) in a printing machine.
The printing form has a surface matrix (1) in which discrete
regions or image points (3) define the image. Each electrical
circuit is associated with a separate region or image point in
the surface matrix. According to appealed claim 1, the only
independent claim on appeal, each electrical circuit includes
at least one threshold value switch (R1, R2 or R3). Claim 1
recites that the resistance of the threshold value switch is
varied between low and high resistance states by a triggering
operation to activate and deactivate the associated region or
image point in the matrix.
A copy of appealed claim 1, as this claim appears in
the appendix to appellant’s brief, is appended to this
decision.
The following reference is relied upon by the examiner
as evidence of obviousness in support of his rejection under
35 U.S.C. § 103:
