`
`INTRODUCTION
`
`Pursuant to 35 U.S.C. § 313 and 37 C.F.R. § 42.107(a), Uniloc Luxembourg
`
`S.A. (“Patent Owner”) submits this Preliminary Response to the Petition for Inter
`
`Partes Review (“the Petition”) of U.S. Patent 7,804,948 (“the '948 Patent”) filed by
`
`Cisco Systems, Inc. (“Petitioner”).
`
`Petitioner has failed to prove that there is a reasonable likelihood that at least
`
`one of the claims challenged in the Petition is unpatentable. See 37 C.F.R. § 42.108(c).
`
`For several different reasons, Petitioner fails to meet this standard for any of the
`
`challenged claims. As non-exhaustive examples, Petitioner: (1) relies on a primary
`
`reference that expressly teaches away from the very limitations for which it is cited;
`
`(2) relies on a combination that changes the principle operation of the primary
`
`reference; and (3) fails to “specify where each element of the claim is found in the
`
`prior art patents or printed publications relied upon.” 37 C.F.R. § 42.104(b)(4). In
`
`view of the reasons presented herein, the Board should reject the Petition in its
`
`entirety.1
`
`
`1 Should the Board institute proceedings in this matter, Patent Owner does not
`concede the legitimacy of any arguments in the Petition that are not specifically
`addressed herein. Patent Owner expressly reserves the right to rebut any such
`arguments in its Patent Owner Response.

`
`
`
`II. BACKGROUND OF THE '948 PATENT
`
`A. Overview of System and Method for Initiating a Conference Call
`
`In general, the '948 Patent discloses and claims various embodiments for
`
`“initiating conference calls via an instant messaging system to reduce the effort
`
`required to initiate and manage the call.” Ex. 1001 at Abstract.
`
`As explained in the Background section of the '948 Patent, certain disclosed
`
`embodiments address “the problem of integrating telephony products into software.”
`
`Ex. 1001 at 2:33-34. Certain technologies, such as private branch exchange or “PBX,”
`
`were encumbered by multiple deficiencies. Id. at 2:33-47. For example, passing the
`
`correct telephony commands to the PBX was problematic because “no two PBX’s are
`
`alike.” Id. Further PBX technology often required “system integrators” and had
`
`reduced scalability opportunity. Id.
`
`Particular systems inefficiently required all users who wanted to join a
`
`conference call to dial in to a central number and enter a passcode, which inhibited
`
`setting up spontaneous conference calls and is subject to serious security risks. Id. at
`
`2:40-58. Other systems enabling host-initiated calls were also inefficient, for
`
`example, in that they typically required someone (such as the host) to separately join
`
`each participant to the call, such as by taking the time to dial or otherwise separately
`
`4
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`identify each conference participants. Id. 2:49-3:20. The above nonlimiting examples
`
`are among the various technological problems that certain embodiments of the '948
`
`Patent overcome.
`
`As disclosed in the specification of the '948 Patent, particular embodiments
`
`make novel use of instant messaging technology to trigger initiation of a host-initiated
`
`conference call. In the embodiment described with reference to Figure 1, for example,
`
`when a “conference call requester” desires to initiate a conference call, a network
`
`access device or “NAD” may efficiently respond to a single request by a “conference
`
`call requester” by generating and sending a “conference request message” that
`
`automatically identifies each of a plurality of potential targets. See, e.g., id. at 7:27-
`
`41; 9:48-67. The “conference request message” may identify multiple parties who are
`
`potential participants or “targets” to a conference call. Id.
`
`In certain instances, the identification of the parties and the initiation of the
`
`conference call may be automatic and at least partially based, for example, on a
`
`determination of the availability of the conference call targets, even if those targets
`
`are not registered with a conference call server. See, e.g., Id. at Figure 2 and
`
`accompanying description; 7:34-38 (“The [Instant Messaging or] IM service in
`
`communication with User A’s NAD could be implemented to be aware of the ongoing
`
`5
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`IM session, such that the software would determine the list of conference call targets
`
`from the list of parties presently in the IM session.”); 9:25-67. The “conference
`
`request message” may be received and processed at a server, for example, which may
`
`then initiate or request initiation of a conference bridge between the conference call
`
`requester and the conference call targets. See, e.g., Id. 6:51-59.
`
`B.
`
`The '948 Patent Claims
`
`The '948 Patent issued with 66 claims. Of those, Claims 1, 23 and 51 are
`
`independent claims. The Petition challenges all independent claims and a majority
`
`(though not all) of the dependent claims. The challenged claims are all written in
`
`method form and recite the following preamble: “[a] method for initiating a
`
`conference call, comprising the steps of ….”
`
`Among other meaningful limitations that are missing from Petitioner’s
`
`proposed combination of references, independent Claims 1 and 23 recite “generating
`
`a conference call request responsively to a single request by the conference call
`
`requester, said conference call request identifying each of the potential targets for said
`
`conference call request.” Similarly, independent Claim 51 recites “generating a
`
`conference call request by the call requester responsively to a single requester
`
`6
`
`indication.”

`
`
`
`C.
`
`Prosecution History of the '948 Patent
`
`The '948 Patent issued from U.S. Application No. 11/019,655 (“the
`
`application”), filed Dec. 22, 2004, which claims the benefit of the U.S. Provisional
`
`Application No. 60/531,722 (the '722 application), filed on December 22, 2003.
`
`D.
`
`Petitioner Oversimplifies the Patented Technology
`
`Petitioner attempts to summarize the '948 Patent technology at pages 3-4 of the
`
`Petition. In doing so, Petitioner grossly oversimplifies the '948 Patent. For example,
`
`Petitioner entirely ignores the claimed advantages achieved at least in part through
`
`automatically generating a conference call request responsively to a single request by
`
`the conference call requester. These deficiencies (among others) are detailed below.
`
`III.
`
`INSTITUTION SHOULD BE DENIED BECAUSE PETITIONER FAILS
`TO ESTABLISH A REASONABLE LIKELIHOOD THAT AT LEAST
`ONE OF THE CHALLENGED CLAIMS IS UNPATENTABLE
`
`The Petition presents the following grounds, which are all based on a theory of
`
`obviousness. As Ground 1, Petitioner alleges obviousness of Claims 1, 2, 5, 6, 8, 12,
`
`18, 19, 21-25, 29, 30, 49-51, and 65-66 under 35 U.S.C. § 103 over Hamberg (Ex.
`
`1005) in view of Lamb (Ex. 1006). As Ground 2, Petitioner alleges obviousness of
`
`dependent Claims 7, 9, 10, 26, 36, 37, 52, and 53 over Hamberg (Ex. 1005) in view
`
`of Lamb (Ex. 1006) and Ludwig (Ex. 1007). As Ground 3, Petitioner alleges
`
`7
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`obviousness of dependent Claim 20 over Hamberg (Ex. 1005) in view of Lamb (Ex.
`
`1006) and Vassilovski (Ex. 1008).
`
`Petitioner has the burden of proof to establish they are entitled to their requested
`
`relief. 37 C.F.R. § 42.108(c). Because the Petition only presents theories of
`
`obviousness, Petitioner must demonstrate a reasonable likelihood that at least one of
`
`the challenged patent claims would have been obvious in view of the art cited in the
`
`Petition. Petitioner “must specify where each element of the claim is found in the
`
`prior art patents or printed publications relied upon.” 37 C.F.R. § 42.104(b)(4).
`
`Petitioner fails to meet this burden.2
`
`A. Claim Construction
`
`Pursuant to 37 C.F.R. § 42.100(b), and solely for the purposes of this review,
`
`Patent Owner construes the claim language such that the claims are given their
`
`broadest reasonable interpretation (“BRI”) in light of the specification of the '948
`
`Patent.3
`
`
`2 While certain deficiencies in the Petition are addressed herein, Patent Owner hereby
`expressly reserves the right to address other deficiencies of the Petition in a full
`Response (and with the support of its own expert) if an inter partes review is
`instituted.
`3 The standard for claim construction at the Patent Office is different from that used
`during a U.S. district court litigation for non-expired patents. See In re Am. Acad. of
`Sci. Tech Ctr., 367 F.3d 1359, 1364, 1369 (Fed. Cir. 2004). Uniloc expressly reserves
`8
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`
`As the Petition appears to recognize, the Specification provides, at the outset of
`
`the section entitled “Detailed Description,” a dictionary-like list of explicit
`
`“definitions” to “more readily describe the present invention.” Ex. 1001, 5:31-6:6.
`
`“Claim terms should generally be given their ordinary and customary meaning, except
`
`‘1) when a patentee sets out a definition and acts as his own lexicographer, or 2) when
`
`the patentee disavows the full scope of a claim term either in the specification or during
`
`prosecution.’” ServiceNow, Inc., v. Hewlett-Packard Co., IPR2015-00699, Paper 12 at
`
`8 (Aug. 20, 2015) (quoting Thorner v. Sony Computer Entm’t Am. LLC, 669 F.3d
`
`1362, 1365 (Fed. Cir. 2012)).
`
`While explicit lexicography should govern, it is unnecessary to construe the
`
`terms Petitioner proposes to address the parties’ disputes. See Vivid Techs., Inc. v. Am.
`
`Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be
`
`construed that are in controversy, and only to the extent necessary to resolve the
`
`controversy.”). Petitioner’s failure to meet its threshold burden here does not turn on
`
`issues of claim construction. Nevertheless, Patent Owner addresses some example
`
`inconsistencies in the Petition with respect to claim construction.
`
`
`the right to argue a different claim construction in litigation for any term of the '948,
`as appropriate in that proceeding.

`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`
`1.
`
`“instant messaging” (all challenged claims)
`
`It is curious that Petitioner does not propose a construction for “instant
`
`messaging,” given that Petitioner seeks a particular construction of that term in
`
`co-pending litigation, admittedly in the hope it may help advance a non-infringement
`
`theory. Specifically, in litigation Petitioner seeks to define “instant messaging” as “a
`
`real-time messaging connection between multiple users.” The Petition, however, is
`
`conspicuously void of any explanation as to (1) why “instant messaging” must be
`
`construed in litigation yet requires no construction here, and (2) how the proposed
`
`combination of references allegedly satisfies Petitioner’s construction in the
`
`co-pending litigation. Failure to include such analysis in the Petition itself severely
`
`prejudices Patent Owner’s ability to offer a preliminary response; and such
`
`gamesmanship should not be rewarded.
`
`It hardly seems equitable that Petitioner could attempt to escape infringement
`
`in district court through an admittedly self-serving construction, and then leave the
`
`same term conveniently unconstrued and unanalyzed when the burden shifts to
`
`Petitioner in its attempt to invalidate the very same claims before the Board. The
`
`respective claim construction standards applied before the Board and in district court
`
`converge on the question of whether a claim term requires construction. Petitioner’s
`
`10
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`inconsistent positions are improper and unreasonable. Cf. Amazon.com, Inc. v.
`
`Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed. Cir. 2001) (“A patent may not,
`
`like a ‘nose of wax,’ be twisted one way to avoid anticipation and another to find
`
`infringement”) (citing White v. Dunbar, 119 U.S. 47, 51 (1886)). The Board should
`
`reject the Petition on this ground alone.
`
`2.
`
`“VOIP address” (Claim 20)
`
`While the Specification does not define the couplet “VOIP address,” the
`
`Specification separately defines both “VOIP” and “address.” As Petitioner
`
`acknowledges, the Specification defines “VOIP” as “Voice over Internet Protocol”
`
`and it defines “address” as “the identifier for where a participant to a conference call
`
`may be contacted.” Ex. 1001, 5:53-54 and 6:6. Concatenating those two explicit and
`
`agreed definitions together yields “a Voice-over-Internet-Protocol identifier for
`
`where a participant to a conference call may be contacted.” Id.
`
`Although it is unclear how it advances Petitioner’s obviousness theory, if at all,
`
`Petitioner appears to propose a narrowing construction for “VOIP address” that
`
`imports limitations from what Petitioner identifies as one of the “non-limiting
`
`examples of an address” disclosed in the Specification. Pet. at 8. Specifically,
`
`Petitioner departs from its acknowledged definition of “address” and, instead, seeks
`
`11
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`to further require additional qualifiers, such as “unique” and “communication path.”
`
`Not only is it impermissible to read in example embodiments as claim limitations,
`
`Petitioner’s construction is inconsistent with the broadest reasonable interpretation
`
`standard applicable here.
`
`B.
`
`Brief Summary of Cited References
`
`1.
`
`Overview of Hamberg (Ex. 1005)
`
`Petitioner neglects to mention to the Board that Hamberg was considered by
`
`the same Examiner during prosecution of a continuation application of the '948
`
`Patent. Although Petitioner curiously opted to cite to a different publication number
`
`(WO0221816), the Hamberg reference cited in the Petition and the Hamberg
`
`reference identified as U.S. Pub. No. 20040013254 on the face of the child U.S.
`
`Patent No. 8,571,194 (“the '194 Patent”) are one and the same.
`
`Patent Owner defers to the description of Hamberg provided during
`
`prosecution of the child application that issued as the '194 Patent:
`
`Hamberg discloses a conference call established between a pre-
`defined group. A server sets up a conference call between the
`subscribers registered with the server as active in a subscriber group.
`(See the Abstract of Hamberg). More specifically, the conference call
`is set up between persons registered to the group at the conference call
`server which establishes the conference call. (See paragraph 25 of
`Hamberg).
`
`
`12
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`
`At least access rights of users, e.g., user names and passwords,
`are required by Hamberg’s registration. Moreover, Hamberg discloses
`that all group members have the right to register as active or inactive
`by sending a special Login message. (See paragraph 16 of Hamberg).
`Hamb[e]rg thus requires an active registration of each subscriber with
`the group at the server establishing a conference call so that the
`conference call can be set up between the registered subscribers.
`
`See Applicant Arguments and Remarks dated July 9, 2012, U.S. Patent Appl. No.
`
`12/907,550 (underlining original).
`
`2.
`
`Overview of Lamb (Ex. 1006)
`
`Petitioner relies on Lamb for its “CONF.NOW” button and “call” button
`
`features. The sole description in Lamb of the “CONF.NOW” button is as follows:
`
`Further note the “CONF.NOW” feature 679-2 of the interface 250. This
`feature allows the user of interface 250 to create a conference at the
`current moment (though in this example, there is already a conference
`underway). This feature was used to create the current conference
`between the user of the user client interface 250 and the other
`participants JOE, SUE, SETH and BILL.
`
`Ex. 1006 at 60:37-43. The paragraph preceding that disclosure in Lamb explains that
`
`the user client interface 250 shown in Fig. 12 shows “selectable participants,”
`
`including JOE, SUE, SETH, and BILL (among others). Id. at 60:18-36. Contrary to
`
`what the Petition suggests, therefore, the process in Lamb for starting a conference
`
`call requires not only pressing the “CONF.NOW” button, but also manually selecting
`
`each one of the participants to be joined to the call.
`
`13
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`
`Moreover, the subsequent paragraph describing “the feature 679-3 ‘FUTURE
`
`CONF.’” states that after that feature/button is selected, “the user is prompted for the
`
`names and a time when the future call is to be set up.” Id. at 60:44-54. While Lamb
`
`is silent as to precisely what happens when “CONF.NOW” is pressed, presumably
`
`that button operates the same way—i.e., after the “CONF.NOW” button is pressed,
`
`the user is prompted to choose between the “selectable participants.” Regardless of
`
`the order of events, it is significant that Lamb’s process for creation of a conference
`
`call requires multiple user actions, including not only a feature/button selection but
`
`also separately selecting each one of the names to be included in the call.
`
`Lamb similarly describes the “call” button feature as follows:
`
`[A] user agent can easily be configured to initiate a large conference
`call with many members (i.e., participants on the connection-based
`telephone network) via the user simply clicking on a conference call
`button in his or her browser. The agent can be preconfigured with the
`appropriate people
`to have
`joined
`in
`the call and
`the
`telecommunications hosting server can control the telecommunications
`network server to setup the required call connections.
`
`Id. 16:25-33 (emphasis added). Lamb further describes the “preconfigured” aspect of
`
`the group to be joined to the call with the following disclosure:
`
`[T]his feature of the invention allows for instance, a manager of a
`number of employees to schedule a conference call with all or some of
`his or her employees at a specified time. The manager can instruct his
`or her user agent 301-1 to send general inter-agent messages to each
`
`14
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`
`employee user agent 301-2 through 301-N to schedule each employee
`for the call as a certain time. The manager simply needs to select the
`employee names from that manager's user client interface 250 and then
`select the conference call feature (as explained with respect to FIG. 12).
`
`Id. at 54:53-63.
`
`C.
`
`Teachings Away from Missing Limitations Prevent a Finding of
`Obviousness
`
`Petitioner alleges invalidity of claims 1, 2, 5, 6, 8, 12, 18, 19, 21-25, 29, 30,
`
`49-51, and 65-66 as allegedly obvious over WIPO Application Publication No.
`
`WO0221816 to Hamberg (“Hamberg”) (Ex. 1005) in view of U.S. Patent No.
`
`6,747,970 to Lamb, et al. (“Lamb”) (Ex. 1006). At a minimum, however, the
`
`references (even if combined) fail to disclose or suggest each independent claim
`
`element. Moreover, both references teach away from the proposed combinations.
`
`Accordingly, a prima facie case of obviousness has not been established and
`
`institution of the Petition should be denied.

`
`Overview of Applicable Law
`
`A patent is obvious “if the differences between the subject matter sought to be
`
`patented and the prior art are such that the subject matter as a whole would have been
`
`obvious at the time the invention was made to a person having ordinary skill in the
`
`art to which said subject matter pertains.” 35 U.S.C. § 103(a). An obviousness

`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`determination must be based on four factual inquiries: (1) the scope and content of
`
`the prior art; (2) the differences between the claims and the prior art; (3) the level of
`
`ordinary skill in the art; and (4) objective indicia of nonobviousness. KSR Int’l Co.

`
`City, 383 U.S. 1, 17-18 (1966)).
`
`If a single limitation of a claim is absent from the prior art, the claim cannot be
`
`considered obvious. See CFMT, Inc. v. YieldUp Int’l Corp., 349 F.3d 1333, 1342

`institute an inter partes review under 35 U.S.C. § 103 where prior art did not disclose
`
`all claim limitations).
`
`“It is improper to combine references where the references teach away from
`
`their combination.” In re Grasselli, 713 F.2d 731, 743 (Fed. Cir. 1983). A prior art
`
`reference teaches away from the claimed invention when a person of ordinary skill,
`
`upon reading the reference, “would be led in a direction divergent from the path that
`
`16
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Prior
`
`art also teaches away when it “criticize[s], discredit[s], or otherwise discourage[s]
`
`investigation into the claimed invention.” See DePuy, 567 F.3d at 1327. Additionally,
`
`“a reference teaches away from a combination when using it in that combination
`
`would produce an inoperative result.” See In re ICON Health & Fitness, Inc., 496
`
`F.3d 1374, 1382 (Fed. Cir. 2007).
`
`Furthermore, the claims cannot be obvious in light of a combination of
`
`elements that changes the principle operation of the prior art reference being applied.
`
`In re Ratti, 270 F.2d 810, 813 (CCPA 1959) (If a proposed modification or
`
`combination of the prior art would change the principle of operation of the prior art
`
`device being modified, then the teachings of the references are not sufficient to render
`
`the claims prima facie obvious.”).
`
`2.
`
`The proposed combination fails to disclose and teaches away
`from “generating a conference call request responsively to a
`single request by the conference call requester”
`
`As recited in independent Claims 1 and 23, the recitation “generating a
`
`conference call request responsively to a single request by the conference call
`
`requester” requires a specific arrangement of distinct elements that the Petition
`
`overlooks. Each claim expressly distinguishes the “single request by the conference
`
`17
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`call requester” from the “conference call request” which, instead, must be generated
`
`(i.e., by the Network Access Device or “NAD”) responsively to that single request.4
`
`Petitioner attempts to combine disparate references in a manner that would
`
`require the conference call requester to not only provide the “single request,” but also
`
`to nonsensically respond to her own request by generating the “conference call
`
`request” as well. Not surprisingly, the cited references teach away from such an
`
`untenable combination. Accordingly, the Petition should be denied in its entirety.
`
`Petitioner alleges that “pressing the ‘Call’ or ‘CONF. NOW’ button [in Lamb]
`
`is a single request by the conference call requester” and that “the CALL ALIAS
`
`message [in Hamberg] is a conference call request.” Pet. at 33 (emphasis original).
`
`Petitioner’s proposed combination admittedly relies on “the mobile stations or
`
`workstations [of Hamberg to] respond to a press of the ‘Call’ or ‘CONF.NOW’
`
`button by generating a CALL ALIAS message.” Id. at 33-34. Petitioner’s theory fails
`
`for at least four independent reasons.
`
`First, Lamb does not disclose that use of its “call” or “CONF.NOW” features
`
`requires only a single request by the conference call requester. On the contrary, as
`
`
`4 Independent Claim 51 similarly recites “generating a conference call request by the
`call requester responsively to a single requester indication.”
`18
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`explained above in the overview of Lamb, the use of either feature requires multiple
`
`requests, including not only selection of the feature/button itself, but also separately
`
`selecting each one of the names to be included in the conference call. Accordingly,
`
`Lamb teaches away from this missing limitation.
`
`Second, Hamberg does not disclose, and in fact teaches away from, requiring
`
`its “mobile stations or workstations” to generate the “CALL ALIAS” message.
`
`Hamberg expressly distinguishes its alternative “CALL ALIAS” embodiment from
`
`its preferred “CALL” embodiment at least in that the sender of the “CALL ALIAS”
`
`text message must manually input within that message the names of each one of the
`
`group members with whom she wants to converse. Ex. 1005 at 6, lines 27-32. In the
`
`context of a “CALL ALIAS” text message, the word “ALIAS” “represents the names
`
`of the group members.” Id. For example, if “the conference call is to be established
`
`with the members LISA, HENRY and ANN,” then to invoke the “CALL ALIAS”
`
`functionality the sender must manually input the text message “CALL LISA HENRY
`
`ANN.” Id.
`
`In other words, Hamberg’s “CALL ALIAS” is only invoked when the sender
`
`manually inputs (as part of the “CALL ALIAS” text message) each one of the
`
`separate alias names she wants joined to the call. Accordingly, Hamberg not only
`
`19
`
`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`fails to disclose that its “mobile stations or workstations” generate the manually
`
`inputted “CALL ALIAS” text message, Hamberg also teaches away from any
`
`combination requiring such a modification. See, e.g., In re Kahn, 441 F.3d 977, 990
`
`(Fed. Cir. 2006) (“A reference may be said to teach away when a person of ordinary
`
`skill, upon reading the reference, would be discouraged from following the path set
`
`out in the reference, or would be led in a direction divergent from the path that was
`
`taken by the applicant.”) (quoting In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994)).5
`
`Third, even if it were appropriate to combine the cited teachings of Hamberg
`
`and Lamb, such a combination fails to disclose the missing limitations. If combined,
`
`the purported “conference call request” would necessarily rely on multiple distinct
`
`requests by a conference call requester, including not only the feature/button press
`
`and the manual selection of each one of the participants in Lamb, but also each one
`
`
`5 Although the Petition does not allege (and has therefore waived) a theory that
`Hamberg’s preferred “CALL” message satisfies the responsive “conference call
`request,” such an argument would have been equally futile. A simple “CALL” text
`message, as described in Hamberg, does not identify “each of the potential targets for
`said conference call request,” as further required by Claim 1. On the contrary,
`Hamberg discloses that after the server-side receives the generic “CALL” text
`message, the server-side must then determine, exclusively using server-side
`information extraneous to the “CALL” text message itself, which members have an
`“active status” registered with the server and therefore should be included in the
`conference call. See, e.g., Ex. 1005 at 6-7.
`20

`
`
`

`
` IPR2017-000058
`U.S. Patent No. 7,804,948
`
`
`
`of Hamberg’s multiple, manually-inputted alias names. A combination requiring the
`
`requester to make multiple, and potentially duplicative requests would vitiate a key
`
`technical benefit emphasized at length in the Specification and unambiguously
`
`reflected in the claim language as “…a single request by the conference call
`
`requester.”
`
`Finally, it is also significant that Claim 1 recites an explicit interrelationship
`
`between the “conference call request” and the “single request by the conference call
`
`requester”–i.e., the former must be generated responsively to the latter. The Petition
`
`points to two unconnected requests found in disparate references; and in a futile
`
`attempt to tie those unrelated requests together, the Petition relies on nonsensical
`
`hindsight reconstruction (as explained above) rather than providing sufficiently
`
`articulated reasoning, with rational underpinning, in view of what the cited references
`
`actually disclose.
`
`Each one of the foregoing reasons provides an independent and fully
`
`dispositive basis to deny the Petition in its entirety as failing to present a prima facie
`
`case of obviousness.

`3.
`
`The proposed combination fails to disclose and teaches away
`from “said conference call request identifying each of the
`potential targets for said conference call request”
`
`Petitioner also overlooks limitations within “said conference call request
`
`identifying each of the potential targets for said conference call request,” as recited
`
`in independent Claims 1 and 23. The missing limitations must be understood in the
`
`context of how the claim further defines “the potential targets.” That limitation has
`
`antecedent basis in the claim language, “a plurality of p
