`
`Reasons to Combine:
`

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`RING discloses communicating messages over a network. RING at Figs. 5 and 7, pp. 88,
`
`
`
`
`
`
`
`

`
`

`
`
`87 and 91. RING does not disclose aggregating payloads into a single aggregated message, but
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Van Hook discloses aggregating group messages into a single packet by bundling the packets.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Van Hook at 2. Van Hook states that “[t]he dominant effect of bundling is to reduce packet
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`rates. Additionally, bundling reduces bit rates because fewer packet headers are sent.”

`
`
`(e. g, “Application Gateway”)(AG)

`While RING does not explicitly disclose forming an aggregated message, it teaches that it
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`is advantageous to aggregate (e.g., “augment”) a client message payload (e.g., an "update

`
`
`
`
`
`
`

`
`PDU”) onto the WAN. Van Hook at 7. The other AGs on the WAN receive the aggregated
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`message (cg, “bundled packet”), unbundle it, and determine which hosts in the group (eg, “cell
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`set,” “Force ID” or “Exercise ID”) should receive the PDU. The AG then transmits the PDUs
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`individually to those recipient host computer in the group (e. g., “cell set”). Van Hook at Figures
`
`
`
`
`
`
`
`
`
`
`
`
`1 and 5; pp. 1, 2, 4, 6, 7.
`
`
`
`
`
`
`
`
`
`
`
`
`The recipient host computer does not w the aggregated message (e.g., “bundled
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`PDU”) because it us unbundled by an AG after being received from the WAN and before being
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`retransmitted to the host computer over the LAN. Van Hook at 7, section 4.6. Nevertheless,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Requester submits that the broadest reasonable interpretation of this element does not require
`
`
`
`
`
`
`
`
`
`
`
`receiving, by a recipient host computer, said aggregated message.
`
`
`
`Instead,
`
`
`
`
`
`the step of
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`“transmitting said aggregated message...” is performed when the AG transmits the bundled PDU

`
`CLAIM 2
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`The method of claim 1 wherein said time interval is a fixed period of time.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`RING discloses the method of claim 1 wherein said time interval is a fixed period of
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`time. RING at Abstract, pp. 85, 86, 87, 90 and 91.
`
`
`
`
`
`
`In particular, RING discloses that update
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`messages are exchanged by servers periodically, indicating messages are exchanged at fixed,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`regular intervals of time. RING at p. 87. Moreover, Van Hook discloses aggregation of packets
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`(e.g., “packets may be bundled together”) to avoid overloading computers. Van Hook at pp. 2
`and 7.
`
`
`CLAIM 4
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`The method of claim 1 further comprising the step of creating, by one of said
`
`
`
`
`
`
`
`
`
`
`
`
`plurality of host computers, said first message group by sending a first
`
`
`
`
`
`
`
`
`
`control message to said server Via said unicast network.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`RING discloses creating the first message group by sending a first control message to the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`server by the unicast network; for example, when a first player enters a “hexagonal shaped cell,”
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`they create a message group consisting of the first player and when other players enter the same
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`“hexagonal shaped cell,” they join the message group created by the first player. RING at p. 90-
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`91 . More specifically, the server creates the "hexagonal shaped cell," but the first player entering
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`the cell creates the first message group, which comprises the players in the cell. 1d. Therefore,
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`RING discloses the creation of the first message group when people enter the “hexagonal shaped
`
`
`
`cell.” Id.

`CLAIM 5
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`The method of claim 4 further comprising the step of joining, by some of said
`
`
`
`
`
`
`
`
`
`
`
`plurality of host computers, said first message group by sending control
`
`
`

`
`group.
`

`
`
`
`
`
`
`RING discloses additional host computers joining the first message group by sending
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`control messages (e.g., “update messages”) to the server indicating that they are joining the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`message group created by the first player. RING at pp. 89.

`CLAIM 6
`
`
`
`The method of claim 1 wherein said network is Internet and said server
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`RING discloses the method of claim 1 wherein the network is the Internet (eg, a wide—
`
`
`
`
`
`
`
`
`
`
`
`
`
`area network”) and the server communicates with a plurality of host computers (e.g., “client
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`workstations”) using a session layer protocol because RING discloses UDP/IP and application
`

`
`
`
`
`
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`uses the UDP/IP protocol, which is a member of the Internet Protocol Suite, the set of network
`

`
`
`
`
`
`protocols used for the Internet. RING at 89, 85, Fig. l 1.
`VI. CONCLUSION
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`The prior art documents presented in the above Request were either not previously
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`considered by the Office during prosecution of the ‘523 patent, or are now being presented in a
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`new light pursuant to MPEP § 2242 (II). None of the six claims of the “523 patent are patentable
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`over the prior art documents cited herein alone or in combination. While Requester has put forth
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`various combinations of the prior art, numerous other combinations are possible. The prior art
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`documents teach the subject matter of the “523 patent in a manner such that substantial new
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`questions of patentability for all six claims of the ‘523 patent are raised by this Request.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`In View of the foregoing, it is respectfully submitted that substantial new questions of
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`patentability of Claims 1—6 of Patent No. 5,822,523 are raised by this Request. Accordingly, the
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Office is requested to grant this Request and to initiate reexamination with special dispatch.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Claims l-6 should be reexamined, rejected under 35 U.S.C. §§ 102-103, and canceled pursuant
`
`
`
`
`
`
`to this Request.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`As an aid to the application of the presented prior art to claims of the ‘523 patent,
`
`
`
`
`
`
`
`
`
`corresponding claim charts are attached hereto.
`Enclosed is a credit card authorization to cover the fee for reexamination.
