`
`NOT
`DISPUTED
`
`63. A method of processing a packet comprising:
`selecting an output interface to which to forward the
`packet;
`determining forwarding permission for the packet, wherein
`the determining comprises
`matching one or more characteristics of said packet
`with one or more access control specifiers in at
`least one access control element;
`processing said packet based on said forwarding
`permission;
`wherein, the selecting step is performed in parallel with the
`determining step.

`

`Cisco’s Arguments For The “Determining . . .” Step
`
`Cisco:
`• Spinney discloses only “determining forwarding
`permission” based on lack of a match, not an affirmative
`match
`• Spinney discloses only that the CAM contains “items,”
`not “one or more access control specifiers”
`• The claimed “access control specifiers” must be access
`control lists (“ACLs”)
`• Spinney’s controller alone is the claimed “access control
`element” so the “access control specifiers” in the CAM
`are not “in” the “access control element”

`Spinney Discloses “Determining Forwarding
`Permissions” Based On A Match As Claimed
`
`Cisco:
`“To the extent the
`‘filtering’ described in
`Spinney relates to the
`dropping of a packet,
`that would at best be
`based on lack of a
`match . . . there is no
`disclosure of filtering
`based on affirmative
`match in the CAM.”

`

`Claim 63 Does Not Require
`“Access Control Specifiers” To Be ACLs
`
`63. A method of processing a 
`packet comprising:
`
`selecting an output interface to 
`which to forward the packet;
`
`determining forwarding 
`permission for the packet, wherein 
`the determining comprises
`
`matching one or more 
`characteristics of said packet 
`with one or more access 
`control specifiers in at least one 
`access control element;
`
`processing said packet based on 
`said forwarding permission;
`
`wherein, the selecting step is 
`performed in parallel with the 
`determining step. 
`
`Ex. 1001 (853 patent) at Claim 63
`
`Institution Decision (Paper No. 8) at 11
`
`Q: Is it your view that claim 63
`requires access control lists?
`
`A: No. Not specifically access
`control lists. I don’t believe
`that that’s language in the
`claim. And I don’t think I’m
`saying that in paragraph 136.

`Assignor Estoppel
`
`“Under the AIA, ‘a person who is not the owner of a patent
`may file with the Office a petition to institute an inter partes
`review of the patent.’ 35 U.S.C. § 311(a) (emphasis added).
`Consequently, under the statute, an assignor of a patent, who
`is no longer an owner of the patent at the time of filing, may
`file a petition requesting inter partes review. This statute
`presents a clear expression of Congress’s broad grant of the
`ability to challenge the patentability of patents through inter
`partes review.”
