`
`Case No. IPR2013-00246
`
`When the CAFC rejected Petitioner Sipnet’s claim construction arguments
`
`in the Sipnet Appeal, Sipnet effectively lost its IPR. In Sipnet’s Petition and Reply
`
`Brief, it provided no argument or evidence that WINS and NetBIOS disclosed the
`
`“is connected” limitations under Straight Path’s—and now the CAFC’s—
`
`construction. Instead, Sipnet chose to rely solely on its proposed “registered”
`
`construction, which the CAFC has now explicitly rejected: “[i]t is not a reasonable
`
`interpretation of the claim language, considering its plain meaning, to say that it is
`
`satisfied by a query that asks only for registration information, regardless of its
`
`current accuracy.” Sipnet at 7. Accordingly, because Sipnet’s entire IPR challenge
`
`is based on an incorrect claim construction, Sipnet has failed to meet its burden of
`
`proving invalidity as a matter of law.
`
`Indeed, Sipnet has effectively admitted its failure to carry it its burden in this
`
`IPR. On remand, Sipnet originally requested leave to file additional briefing so that
`
`it could present invalidity arguments under the now-controlling claim construction
`
`established in the Sipnet Appeal. (See Paper No. 68 at 2). But when the Board
`
`ordered that the additional briefing “shall not include any new evidence or any new
`
`argument” and further required Sipnet to “provide citations in the [requested]
`
`additional briefing to those portions of the previously existing record where the
`
`argument were originally introduced” (Paper No. 68 at 2-3), Sipnet informed the
`
`
`
`1
`
`
`
`
`
`Case No. IPR2013-00246
`
`Board that it would not be filing the requested additional briefing after all, thereby
`
`tacitly admitting that Sipnet had not previously presented any invalidity arguments
`
`or evidence under the now-controlling claim construction. (Exhibit 2052).
`
`Nor could Sipnet have reasonably presented any such argument or evidence,
`
`because all of the evidence of record establishes that the WINS and NetBIOS
`
`references do not teach the “is connected” limitations under the CAFC’s
`
`controlling claim construction.
`
`I.
`
`The CAFC’s Construction Of “is connected” Is Controlling
`
`It is undisputed that each challenged claim requires a determination of
`
`whether a process “is connected to the computer network” or some variation
`
`thereof, such as “currently connected to the Internet” or “on-line.” (R at 19-25;
`
`‘704 patent at claims 1-7, 32-42). For example, representative challenged claim 1
`
`is directed to a “computer program product” that (1) transmits to the server a
`
`“query as to whether the second process is connected to the computer network,”
`
`and (2) receives the second process’s network protocol address from the server
`
`“when the second process is connected to the computer network.” (R at 2, 4, 16-
`
`17, 19-20; ’704 patent at claim 1).
`
`In Sipnet, the CAFC construed the “is connected to the computer network”
`
`limitation “and the counterpart claim phrases that the parties agree bear the same
`
`
`
`2
`
`
`
`
`
`Case No. IPR2013-00246
`
`meaning . . . to mean ‘is connected to the computer network at the time that the
`
`query is transmitted to the server.’” Sipnet at 13 (emphasis added). There is no
`
`dispute that the CAFC’s construction is controlling here. See, e.g., Phonometrics,
`
`Inc. v. Westin Hotel Co., 350 F.3d 1242, 1244-1245 (Fed. Cir. 2003).
`
`II. WINS and NetBIOS Do Not Teach The “is connected” Limitations
`Under The CAFC’s Construction
`
`Unlike the challenged claims under the CAFC’s construction, WINS and
`
`NetBIOS do not describe any mechanisms for tracking or determining whether a
`
`computer (much less the claimed process) is connected to the computer network at
`
`the time of the query, nor do they describe any mechanism for sending the
`
`requested target’s address dependent on if that target is in fact connected to the
`
`computer network at the time of the query. (R at 2-3, 17, 31-46). Indeed, the art
`
`explicitly admits it cannot: “[a]ny name-to-IP address mapping registered with a
`
`WINS server can be provided reliably as a response to a name query. However, a
`
`mapping in the database does not ensure that the related device is currently
`
`running.” (Ex. 1004 at 72-74; R at 2-3, 17, 31-46).
`
`This is because whether a computer is online is not tracked or considered by
`
`the WINS and NetBIOS name servers. (Ex. 1004 at 64-70, 72-75; Ex. 1003 at 377-
`
`378, 394-398; R at 2-3, 17, 31-46). Rather, name servers have a different purpose,
`
`
`
`3
`
`
`
`
`
`Case No. IPR2013-00246
`
`i.e., enabling one computer to request another target computer’s IP address by
`
`name. (Ex. 1004 at 64-70, 72-75, 121; Ex. 1003 at 377-378, 394-398, 406; R at 17,
`
`31-32, 39-40). To this end, the WINS and NetBIOS name servers have two
`
`primary functions: (1) Registration, by which the name server ensures that two
`
`different computers do not claim the same name and (2) Resolution, by which the
`
`name server determines and returns a computer’s address when that address is
`
`requested using the computer’s name. (Ex. 1004 at 64-70, 72-75; Ex. 1003 at 377-
`
`378, 394-398, 406-409; R at 31-36, 39-44). In performing these functions, the
`
`WINS and NetBIOS servers do not check or rely on whether any particular
`
`computer (or process) is online. (Ex. 1004 at 64-70, 72-75; Ex. 1003 at 394-398,
`
`406-409; R at 2-3, 17, 31-46).
`
`A. WINS and NetBIOS do not track or rely on whether a computer
`is connected to the network.
`
`During Registration, a computer tries to register a name, and the name server
`
`then checks if another computer is already using that name. (Ex. 1004 at 64-70, 72-
`
`75; Ex. 1003 at 378, 394-400, 402-405, 412-414; R at 31-36, 39-44). If any
`
`computer previously registered that name, the server checks if that computer has
`
`relinquished its claim to (has “released”) that name. (Ex. 1004 at 64-68, 72-75; Ex.
`
`1003 at 378, 394-400, 402-405, 411, 412-414; R at 31-36, 39-44). During
`
`
`
`4
`
`
`
`
`
`Case No. IPR2013-00246
`
`Resolution, a first computer asks the name server for a second computer’s address
`
`using that second computer’s name (a “name query”); the server then searches its
`
`database for an address mapped to the queried name and, if a mapping exists,
`
`returns that address to the first computer. (Ex. 1004 at 64-70, 72-73; Ex. 1003 at
`
`395, 406-409, 415-417; R at 31-36, 39-44).
`
`At no time during Registration or Resolution does the WINS/NetBIOS name
`
`server try to determine if any computer is currently online. (Ex. 1004 at 64-70, 72-
`
`75; Ex. 1003 at 378, 395-400, 402-409, 411-417; R at 2-3, 17, 31-46).
`
`B. Whether a name has been released does not indicate whether any
`particular computer is connected to the computer network.
`
`Whether a computer has released a name is no indication of, and cannot be
`
`relied on to show, whether that computer is connected to the computer network
`
`under the CAFC’s construction. (Ex. 1004 at 64-70, 72-73; Ex. 1003 at 395, 406-
`
`409, 415-417; R at 31-36, 39-44). A computer that is offline can still have a
`
`registered, unreleased name. (Ex. 1004 at 72-75, 129-131, 148-149; Ex. 1003 at
`
`378, 394-400, 402-405, 411-414; R at 31-36, 39-44). Conversely, a computer that
`
`is online can release its name yet stay connected to the computer network. (Ex.
`
`1004 at 72-75, 129-131, 148-149; Ex. 1003 at 378, 395, 398, 400, 411; R at 31-36,
`
`39-44).
`
`
`
`5
`
`
`
`
`
`Case No. IPR2013-00246
`
`For example, a computer may have a permanent name that is never released,
`
`even when the computer is offline. (Ex. 1004 at 138-143; Ex. 1003 at 394, 396,
`
`411; R at 31-36, 39-44). Even a computer with a temporary name may go offline
`
`without releasing its name—which the references themselves admit is “common”
`
`and “occurs frequently”—and its name will stay unreleased until and unless a
`
`second computer attempts to register the same name and successfully challenges
`
`the first computer’s registration. (Ex. 1004 at 72-75, 129-131, 148-149; Ex. 1003 at
`
`378, 394-400, 402-405, 411-414; R at 31-36, 39-44).
`
`C. The WINS and NetBIOS name servers return a requested IP
`address regardless of whether the target computer is online or
`whether the queried name has been released.
`
`Just as the name server does not attempt to determine whether any computer
`
`associated with a queried name is connected to the network during Resolution, it
`
`also does not attempt to determine whether the queried name has been released.
`
`(Ex. 1004 at 64-68, 72-74; Ex. 1003 at 394-398, 406-409, 415-417; R at 31-36, 39-
`
`44). Once a name is mapped to an IP address, the name server will continue to
`
`provide that address in response to a name query—regardless of whether the target
`
`is online or the name has been released—until that name is removed all together
`
`from the database. (Ex. 1004 at 64-68, 72-74; Ex. 1003 at 395, 406-409, 415-417;
`
`R at 31-36, 39-44).
`
`
`
`6
`
`
`
`
`
`Case No. IPR2013-00246
`
`Thus, even if a name’s released status did somehow correspond to whether a
`
`computer was in fact online—and it does not—that name status has no effect on
`
`whether the name server will return a requested IP address. (Ex. 1004 at 64-68, 72-
`
`74; Ex. 1003 at 394-398, 406-409, 415-417; R at 31-36, 39-44).
`
`III. Conclusion
`For these reasons previously established in the IPR record, the Board should
