teaches processing the parameters of the incoming frame to determine which
course of action to take, as well as to produce an outgoing frame for use by
an external circuit. (Findings of fact 6 and 9.) Additionally, we have found
that Ogawa teaches that the external circuit can be separated from the
receiving circuit by a firewall. (Finding of fact 11.) In light of these
findings, it is our view that Ogawa’s teachings amount to reading and
processing parameters of an incoming frame in a first network to produce an
outgoing frame for use in a second network. It follows that the Examiner
did not err in rejecting independent claim 1 as being anticipated by Ogawa.
As per claims 2 and 3, we have found that Ogawa teaches reading an
incoming parameter to extract the length and offset of the parameter prior to
processing the parameter. (Finding of fact 6, footnote 5.) It follows that the
Examiner did not err in rejecting claims 2 and 3 as being anticipated by
Ogawa.
As to claims 4 through 6, we have found that Ogawa teaches routing
the extracted parameters of an incoming frame to an encapsulation circuit
block and a data pipeline register block to process said parameters, as well
as to produce parameters for an outgoing frame to be used by an external
circuit, which may be separated from the receiving circuit by a firewall.
(Findings of fact 7 through 11.) It follows that the Examiner did not err in
rejecting claims 4 through 6 as being anticipated by Ogawa.
As to claim 7, we have found that Ogawa teaches at least two
processes including a counter process and a comparison process during
which the parameters of incoming frame are manipulated to produce
parameters for an outgoing frame for use in the external circuit. (Finding of
fact 9.)
