image. Column 1, lines 32-50, of Bhaskaran makes it clear that the reference envisions
“electric circuit element symbols” being converted into digital data that can be input to
various CAD systems.
As the examiner recognizes [answer-page 4], Bhaskaran is “silent about specific
details regarding non-pictorial description.” Therefore, the examiner turns to Rostoker for
a teaching of “creating and verifying structural logic model of electronic design from
behavioral description including generation of logic and timing models comprising the step
of generating non-pictorial description and listing of the electronic circuits” [answer-page 5,
citing figure 2 and elements 205 (206?), 208, 210 and 212, as well as column 22, lines 45-
68 of the reference]. The examiner also relies on Rutenbar for disclosing “routing
techniques using serial neighborhood image analyzing system comprising the step of
generating interconnections among the inputs and outputs (column 4, lines 10-55)”
[answer-page 5].
The examiner then concludes that it would have been obvious to use the step of
generating a non-pictorial description, as described by Rostoker, and the generation of
input and output terminals of the logic components and all interconnections among them,
as taught by Rutenbar, in the system of Bhaskaran because the secondary references
“merely provide the details of most frequently used logic symbols and a
