`
`INTRODUCTION
`
`A. No Rebuttal Testimony
`
`Petitioner’s Reply does not include any rebuttal testimony from an expert
`
`even though it could have. Practice Guide at 73. As a result, Petitioner’s Reply is
`
`based on attorney argument and the original Petition Declaration. More
`
`importantly, Dr. Rouskas’s POR Declaration and his deposition testimony stand
`
`unrebutted.
`
`
`
`
`
`B.
`
`Petitioner’s Attacks On Dr. Rouskas Are Baseless
`
`First, Petitioner cross-examined (deposed) Dr. Rouskas for two days. Exhibit
`
`1043. Dr. Rouskas testified at length regarding his opinions to the point that
`
`Petitioner’s counsel interrupted Dr. Rouskas because Petitioner believed that Dr.
`
`Rouskas’s testimony was too detailed. Id. at 265-66. Tellingly, Petitioner does not
`
`cite to any cross-examination question that Dr. Rouskas was not able to answer.
`
`Dr. Rouskas testified that the opinions expressed in his Declaration (Exhibit 2001)
`
`are his own and that he spent “anywhere between 80 and 100 hours” preparing his
`
`Declaration. Id. at 24-25.
`
`
`
`Second, Petitioner’s reliance on Hulu and Juniper Networks is inapplicable.
`
`Petitioner failed to provide a single example of how Dr. Rouskas’s testimony is
`
`“cursory or unsupported”. That the POR relies upon and incorporates Dr.
`
`Rouskas’s testimony is the norm in IPR practice. Doing otherwise risks exclusion.
`
`
`
`1
`
`
`
`Practice Guide at 35-36 (Ҥ 42.6(a)(3) prohibits incorporating arguments by
`
`reference from one document into another. Thus, parties that incorporate expert
`
`testimony by reference … risk having the testimony not considered by the
`
`Board.”).
`
`
`
`Finally, the rule of completeness shows that Dr. Rouskas did not contradict
`
`his Declaration testimony. Fed. R. Evid. 106. Indeed, Petitioner had four attorneys
`
`and its expert, Dr. Almeroth, attend in person Dr. Rouskas’s deposition. Exhibit
`
`1043 at 3-4. Petitioner’s five-person team huddled during breaks to review the
`
`real-time transcript in an effort to create out of context “sound bites” that Petitioner
`
`could use to distort Dr. Rouskas’s testimony by asking, re-asking, and asking again
`
`the same question in a manner that would never be allowed in a “live” trial. Of
`
`course, Petitioner’s Reply never addresses any one of PO’s objections to
`
`Petitioner’s “asked and answered” questioning scheme.
`
`Rather than trying to tarnish the reputation of a Distinguished Graduate
`
`Professor at N.C. State University, a better approach would have been to submit a
`
`rebuttal declaration from Dr. Almeroth who theoretically could have rebutted Dr.
`
`Rouskas’s testimony if it truly is so baseless. Exhibit 2008 at 1; Exhibit 1043 at 4.

`
`
`
`II. GROUND I – DIACAKIS DOES NOT OBVIATE CLAIMS 7, 10-12,
`22-24, 33-36, 38-41, 46, 49, 51-53, 55, 57-58, OR 64-66
`
`A.
`
`[7.0] Diacakis Does Not Teach A Network Based Portal (“NBP”)
`
`
`
`
`
`The Reply “first” argues that there is nothing to limit the claimed portal to a
`
`server or a website. Reply at 5. The POR shows that in the ʼ038 patent a “portal”
`
`and a “gateway” are used synonymously; and a “gateway” is a “networked server”.
`
`POR at 11-12. Petitioner’s Reply is incorrect and is not supported by any rebuttal
`
`expert testimony.
`
`Petitioner’s unsupported arguments are contradicted by Petitioner’s Reply
`
`Exhibit 1042, which states “[a] mobile portal is an Internet gateway that enables
`
`mobile devices to connect remotely ... typically via a Web browser interface.”
`
`Thus, Exhibit 1042 defines a “portal” as an Internet “gateway” and differentiates it
`
`from a web browser interface, which is only used to connect a device to the portal.
`
`The definition of a portal in Exhibit 1042 is consistent with Dr. Rouskas’s
`
`testimony. Exhibit 1043 at 90:4-9, 91:10-15. As explained, when a user wishes to
`
`connect to a portal, they type the URL of the portal in the browser interface of their
`
`device and establish a connection to the portal which is a computer/server distinct
`
`from the user’s device. Id. at 80:7-81:22. Reply Exhibit 1041 also contradicts
`
`Petitioner’s attorney-only arguments as it defines a “portal” as a “platform,” not a
`
`user interface. Exhibit 1041.
`
`
`
`3
`
`
`
`Moreover, that a definition includes the term “interface” does not mean a
`
`“portal” is an interface. The term “interface” is used to indicate how a user
`
`accesses the portal (i.e., via a web browser interface), not what a portal is. A web
`
`browser (as in Petitioner’s definition) is an interface found on all client devices
`
`(computers, laptops, phones, etc.) whether those devices access a portal or not. As
`
`Dr. Rouskas explained, a user uses their device’s web interface to request content
`
`stored at the portal, not on the user’s device. The portal sends the content to the
`
`user’s device after it receives the request, and the content is simply displayed on
`
`the device via the web browser interface. Exhibit 1043 at 80:1-81:22.
`
`Regarding “hosting” a web page, the Petitioner’s exhibit expressly states that
`
`devices access the portal by “connect[ing] remotely ... typically via a Web browser
`
`interface.” Exhibit 1042. Since the devices use a “Web browser interface” they
`
`must necessarily connect to a website hosted at the portal. Id. In fact, the Figure in
`
`Petitioner’s Exhibit 1041 shows a “portal” that is consistent with PO’s evidence
`
`and Dr. Rouskas’s deposition testimony that a “portal” is not a “user interface” but
`
`rather at least includes the server hosting the site WWW.COMPANY.COM (a
`
`website), accessible by many:
`
`
`
`4
`
`
`
`
`
`Exhibit 1041 at 2. User RAY in the figure types the URL into his browser to
`
`connect to the server of the portal site; the server collects information from various
`
`sources at the site to present to user RAY via the web browser interface. Exhibit
`
`1043 at 80:7-81:22. “Portals represent an early paradigm shift for enterprises
`
`online, which was to build websites that were customer-centric, rather than
`
`business-centric. Ideally, a portal enables an enterprise to design sites and
`
`navigations that are based on the user’s needs, rather than an organizational
`
`structure that only makes sense internally.” Exhibit 1041 at 3 (emphasis added).
`
`Second, the Reply argues that PO incorrectly argues the ʼ038 patent defines
`
`“portal” as a “gateway” and that a gateway is always a “networked server.” Reply
`
`at 6-7. As shown above, however, Petitioner’s Exhibit 1042 also defines “portal”
`
`as a “gateway”. Indeed, Dr. Rouskas’s testimony that to a POSITA the word “or”
`
`in the specification means that “portal” and “gateway” are used synonymously is
`
`
`
`5
`
`
`
`unrebutted. POR at 11-12; Exhibit 1043 at 90:4-9, 91:10-15. Petitioner therefore
`
`failed to meet its burden of proof. 37 C.F.R. § 42.1(d); Practice Guide at 42.
`
`Third, the Reply argues that it is a “distinction without a difference” that the
`
`NBP and client devices have different functionalities because the NBP allows
`
`worldwide access to the user, whereas a client communication device is associated
`
`with a user. Reply at 8-9.
`
`Petitioner claims that “Diacakis’s client terminal connects a user to a
`
`network via the NBP.” This statement is wrong because (1) Diacakis only
`
`describes messages related to the management of P&A information, not direct
`
`communication between users, and (2) interface 112 (i.e., the Petitioner’s claimed
`
`NBP) cannot be used to send or receive user messages. Exhibit 1043 at 134:3-
`
`135:4 and 417:17-21. Petitioner conflates messages related to management of
`
`P&A information with direct messages between users. As Dr. Rouskas explained,
`
`and as Diacakis teaches, the Diacakis P&A system operates in a publisher-
`
`subscriber model. Exhibit 1043 at 141:5-142:12. When the profile of an individual
`
`changes, these changes are sent to the P&A server; the server then forwards the
`
`updated contact information to the subscribers. Id. However, the Diacakis system
`
`cannot be used by one user to call or send communication messages directly to
`
`another user. Id.
`
`
`
`6
`
`
`
`Interface 112 cannot be used to send or receive any user messages and may
`
`only receive contact information from the P&A server. Hence it does not provide
`
`“worldwide access to the user.” As Dr. Rouskas explained, whether a user’s
`
`mobile phone allows worldwide access to that user is irrelevant, as the Petition
`
`does not point to the “mobile phone” as the claimed NBP, but rather argues that
`
`interface 112 of Diacakis is the claimed NBP. Exhibit 1043 at 415:23-416:6 and
`
`417:17-21. To communicate with other users (i.e., make or receive calls, emails,
`
`or IMs), a user must interact with specific application interfaces (i.e., the Phone,
`
`Email, or IM interface, respectively) that allow for the sending or receipt of user-
`
`to-user messages. Just because a phone allows worldwide access to a user does not
`
`imply that the interface 112 of Diacakis also provides worldwide access to the user
`
`because the interface 112 cannot be used for user-to-user communication.
`
`Further, as Dr. Rouskas explained, Diacakis uses double-headed arrows in
`
`Fig. 11 to denote bidirectional communication:
`
`
`
`7
`
`
`
`Exhibit 1007, Fig. 11. However, Diacakis expressly uses a single-headed arrow in
`
`Fig. 9 to denote communication only in the direction from the P&A server to the
`
`client device 22:
`
`
`
`
`
`Exhibit 1007, Fig. 9. Since Diacakis understood that double-headed arrows
`
`correspond to “bidirectional movement of communication” (Exhibit 1043 at 212:8-
`
`10), if Diacakis wanted to also indicate communication to the P&A server Diacakis
`
`
`
`8
`
`
`
`would have used a double-headed, not single-headed arrow. This is consistent
`
`with the teachings of Diacakis (Ex. 1007 at [0064]) that “the indicator module 110
`
`may receive availability information from one or more P&A management servers
`
`12 … for display by the user interface 112”. Nothing in Diacakis indicates that a
`
`user may use interface 112 to either receive or send communication messages to
`
`other users. Figure 9 expressly shows that interface 112 is only connected to the
`
`Indicator module 110 and only for displaying information that module 110 receives
`
`from the P&A server. Interface 112 is not connected to any module that can be
`
`used for user-to-user communication. Due to the single-headed arrow, Fig. 9 does
`
`not allow for any communication from interface 112, either to the P&A server or to
`
`other users, and hence it cannot be used for sending messages from a first user to a
`
`second user, as the claim requires. Finally, since modules 110 and 112 of Fig. 9
`
`only receive information from the P&A server, module 112 cannot receive user-to-
`
`user messages and hence it cannot allow “worldwide access” to the user. Exhibit
`
`1043 at 415:4-419:24.
`
`
`
`Fourth, the Reply argues that PO made a strawman argument “that only the
`
`sender’s device contains the NBP”. Reply at 8. Petitioner’s argument contains
`
`several incorrect statements. First, it states “[a]s the Petition explained, Diacakis’s
`
`users provide their contact information to a P&A server” which “is different from
`
`the NBP.” As Dr. Rouskas testified, the Diacakis P&A system operates in a
`
`
`
`9
`
`
`
`publisher-subscriber model. Exhibit 1043 at 140:10-141:3. When the profile of an
`
`individual changes, these changes are sent to the P&A server; the server then
`
`forwards the updated contact information to the users, i.e., to interface 112, for
`
`display. Hence, the contact information is indeed sent to Petitioner’s claimed
`
`NBP, interface 112, for display. Exhibit 1043 at 202:1-4.
`
`
`
`Second, the Reply incorrectly states “all users … use Diacakis’s [alleged]
`
`NBP to connect to Diacakis’s network.” Reply at 8. This is not true; as explained
`
`above, interface 112 may only receive messages from the P&A server. Hence, it
`
`even cannot be used to connect users to the P&A server.
`
`Third, Petitioner mischaracterizes PO’s argument and is incorrect in stating
`
`that “all users (including senders and recipients) use Diacakis’s NBP to connect to
`
`Diacakis’s network):
`
`
`
`10
`
`
`
`
`
`
`
`
`
`Reply at 8-10 (emphasis in original). Figures 1 and 9 do not indicate to a POSITA
`
`that “both senders and recipients use this interface.” First, interface 112,
`
`Petitioner’s claimed NBP, can only receive information from the P&A server (see
`
`above). Specifically, the interface 112 in Diacakis’s system is for a user to receive
`
`contact information of individuals they wish to contact: “Fig. 9 is a block diagram
`
`of the client terminal 22 … for realizing the single indicator described previously.
`
`… The indicator module 110 may receive availability information from one or
`
`more P&A management servers 12 and merge the contact information for each
`
`individual into a single indicator … for display by the user interface 112.” Exhibit
`
`1007 at Fig. 9, [0063]-[0064]. Exhibit 1043 at 419:6-13.
`
`
`
`Diacakis’s system will also have another interface (not shown in any figure
`
`of Diacakis) that allows the user to connect to the P&A server to provide their
`
`
`
`11
`
`
`
`contact information to the server and configure their profile and access groups.
`
`Exhibit 1007 at [0031], [0036]. But that interface is separate from interface 112.
`
`The Diacakis system must implement different interfaces, one for
`
`configuring the contact information, profiles, and access groups, and one for
`
`receiving contact information: the former is a configuration function while the
`
`latter is a digital phonebook (i.e., a Contacts app). Accordingly, Diacakis discusses
`
`the two interfaces separately. The configuration interface is discussed in paragraph
`
`[0036] within the section spanning paragraphs [0031]-[0037] that is concerned
`
`with user profiles and their configuration. Interface 112 is concerned with
`
`displaying the contact info related to the single indicator, and is discussed in
`
`paragraphs [0063]-[0064] within the section spanning paragraphs [0059]-[0068]
`
`that describe the Diacakis indicator. The fact that Diacakis discusses the two
`
`interfaces separately and expressly states that the embodiment of Fig. 9 only
`
`receives information from the P&A server specifically “for display by the user
`
`interface 112” indicates to a POSITA that interface 112 is not used for connecting
`
`users to the network. Exhibit 1007 at Fig. 9, [0031], [0036], and [0063]-[0064];
`
`Exhibit 1043 at 419:6-13.
`
`
`
`Fifth, regarding whether PO’s construction excludes a preferred
`
`embodiment (Fig. 7-12), the Reply argues that “because the patent’s figures are
`
`embodiments of the patent, they must include an NBP.” Reply at 10. Petitioner
`
`
`
`12
`
`
`
`completely fails to address the POR’s evidence explaining why Figs. 7-12 are not
`
`directed to the use of a NBP. POR at 19-21. Petitioner’s position that every issued
`
`claim must encompass every figure/embodiment of a patent is wrong as a matter of
`
`law. The fact is that PO’s evidence submitted after the Institution Decision shows
`
`that a POSITA would understand that the embodiments of Figs. 7-12 are not
`
`directed to NBP operations but are instead directed to client-side operations at a
`
`client device; and this post-institution evidence stands unrebutted. Id.
`
`
`
`Petitioner’s argument that “the client devices described by the ʼ038 Patent
`
`enable messages to be received, as annotated in Figure 7 below” is irrelevant and
`
`side-steps PO’s argument:
`
`
`
`13
`
`
`
`
`
`Reply at 11. Indeed, Figure 7 does not teach a POSITA the use of a NBP. POR at
`
`19-21. As evidenced in the POR:
`
`“Fig. 7 is a flow diagram of a personal call response process 200
`according to one embodiment of the invention. The personal call
`response process 200 is performed by an electronic device, such as a
`mobile communication device (e.g., mobile telephone).
`
`
`POR at 19-20. Similar language is used in describing Figures 8-12. POR at 20.
`
`Figures 7-12 concern how a recipient user interacting with their client device can
`
`respond to an incoming call or message. As a result, a construction that has the
`
`
`
`14
`
`
`
`NBP at a server distinct from the second user’s communication device does not
`
`exclude a preferred embodiment, if anything, it enables them. POR 20.
`
`
`
`B.
`
`[7.1] Diacakis Does Not Teach A “Prior Registration Process”
`
`The POR proves that Diacakis does not teach a POSITA the claimed
`
`registration process because a user in Diacakis does not go through a registration
`
`process with their contacts app. POR at 21-22. Petitioner’s Reply is incorrect and
`
`is not supported by any rebuttal evidence from the perspective of a POSITA. Reply
`
`at 12.
`
`
`
`Petitioner argues that Diacakis teaches a “prior registration process by the
`
`first user regarding the use of the network-based portal” because a subscriber
`
`subscribes to the second user. Reply at 12. However, Diacakis teaches that clients
`
`are “subscribers of the individual’s information.” Exhibit 1007 at [0029]. Even
`
`assuming that a subscription process is equivalent to a registration process, the
`
`subscription is not “regarding the use of” the interface 112 (Petitioner’s alleged
`
`NBP) on the subscriber’s (the first user’s) device, but regarding a different
`
`individual’s (the second user’s) contact information. As the POR states, interface
`
`112 is an application on the subscriber’s device and “they simply open it and use
`
`it.” POR at 22. Even before a user subscribes to the information of any individual,
`
`i.e., before going through any subscription process, they would open and use
`
`interface 112 on their device.
`
`
`
`15
`
`
`
`C.
`
`[7.3] The Diacakis Indicator Is Not Used To Send Or Receive
`Messages Between Users
`
`The POR proves that the Diacakis indicator is not used to send or receive
`
`
`
`user-to-user messages. POR at 22-25. Petitioner’s Reply argument is incorrect and
`
`is not supported by any rebuttal evidence from the perspective of a POSITA. Reply
`
`at 14. Diacakis expressly teaches that “the single summary indicator may be a
`
`summary of the individual’s availability” and hence, as the POR states, the
`
`“indicator is not for, and cannot be used to, receive messages.” Exhibit 1007 at
`
`[0059]; POR at 23.
`
`According to Diacakis “the single summary indicator contain[s] several
`
`different icons or states, .... the icons may indicate types of data the individual is
`
`available to receive such as, for example, text files audio files ….” As the POR
`
`explains, when a user selects indicator “Jonathan” in Fig. 8 of Diacakis, the
`
`availability information of contact “Jonathan” is shown in the left-hand side of Fig.
`
`8 and no communication transpires. Exhibit 1007 at [0059]; POR at 23-24.
`
`
`
`Petitioner’s Reply does not contest PO’s arguments that (1) a POSITA
`
`would understand that “Jonathan” may not be used to “receive [any] messages”, let
`
`alone “all of the communications”, or (2) if a user selects “Jonathan” no
`
`communication transpires. POR at 23-25. Petitioner’s failure to address these
`
`points is an admission that Ground I of the Petition should be denied.

`
`
`
`
`
`
`
`D.
`
`[7.5] Diacakis’s P&A System Does Not Teach Or Support Sending
`Messages Between Two Users
`
`The POR proves that Diacakis’s P&A system does not teach or support
`
`sending messages between users. POR at 22-25. Petitioner’s Reply argument is
`
`incorrect and is not supported by any rebuttal evidence from the perspective of a
`
`POSITA. Reply at 12-15.
`
`
`
`Petitioner accurately characterizes the Diacakis system as a “digital
`
`phonebook.” Reply at 14. As Dr. Rouskas explained, Diacakis expressly limits the
`
`scope of the invention (i.e., the P&A management system) to two primary and two
`
`secondary functions that are unrelated to user-to-user communication. Exhibit
`
`1043 at 134:9-135:4; 201:22-202:17. The two primary functions are: (i) “to collect
`
`information from multiple sources to determine the presence and ... the availability
`
`of a given person” and (ii) to “distribute the availability information of a given
`
`person to interested individuals on a selective basis.” Id. The two secondary
`
`functions are (i) “to configure access control settings” and (ii) “to store user
`
`information to enable the use of the presence and availability management service
`
`regardless of the user's network device.” Id.
`
`Dr. Rouskas further explained that Fig. 8 of Diacakis shows the information
`
`displayed by interface 112 (the alleged NBP). Exhibit 1043 at 201:22-202:17. This
`
`information includes a list of names and their contact, presence, and availability
`
`information, which is what the Diacakis system manages. Therefore, it is a “digital
`17
`
`
`
`
`
`phonebook.” Reply at 16; Exhibit 1007 at [0006]-[0007], [0056], and [0064]; and
`
`Exhibit 1043 at 134:9-135:4, 201:22-202:17.
`
`The fact that Diacakis may disclose that a user may communicate with
`
`another user is irrelevant. Contrary to Petitioner’s attorney argument, “a system
`
`that actually allows a user to make a communication” is not shown in Fig. 11:
`
`
`
`Reply at 12. Rather, Fig. 11 simply shows “relay hosts” that relay (i.e., forward)
`
`messages. Exhibit 1007 at [0072]-[0073]. As Dr. Rouskas explained, message
`
`forwarding takes place every time a user, e.g., makes a call, and the Diacakis
`
`system is not involved in the initiation of the call. Exhibit 1043, 421:18-422:2 and
`
`422:19-423:6. There is nothing in Diacakis, within Figure 11 or elsewhere, that
`
`teaches, or even implies, that the Diacakis P&A system may be used to initiate or
`
`carry out user-to-user communication. Id.
`
`
`
`18
`
`
`
`
`
`That the Diacakis’s P&A system does not teach or support sending messages
`
`between two users is also evidenced by the fact that all embodiments of a P&A
`
`server/system in Diacakis are limited to the exchange of P&A information. As
`
`explained below, no embodiment provides even a hint or indication that the
`
`Diacakis system may be used for user-to-user communication. Id.
`
`Figure 1 of Diacakis and the accompanying discussion clearly show that the
`
`P&A server 12 consists of a presence detection engine, an availability management
`
`engine, and a profile database, and its function is to receive profile information
`
`from clients and forward P&A information to subscribers in a publisher-subscriber
`
`model. Exhibit 1007 at Fig. 1 and [0024]-[0031]. There are no components for
`
`enabling or carrying out direct user-to-user communication and no such
`
`communication is indicated in Fig. 1 as the P&A server is shown connected to a
`
`single client terminal. Id. Figure 3 of Diacakis and the corresponding text only
`
`show and discuss the configuration of profiles stored at the P&A server and the
`
`transmission of the P&A information (including contact information, as shown in
`
`Fig. 8, [0056] and [0064]) to subscribers at various access groups. Again, no user-
`
`to-user communication is indicated or implied. Exhibit 1007 at Fig. 3 and [0033]-
`
`[0037].
`
`Figure 4 of Diacakis and the accompanying text again show that the P&A
`
`server 1) only collects P&A information from the clients and 2) only transmits
`
`
`
`19
`
`
`
`availability information (including contact information, as explained above) to the
`
`subscribers. There are no diagrams or discussion of any components used for user-
`
`to-user communication. Exhibit 1007 at Fig. 4 and [0038]-[0048].
`
`Figure 5 is a “diagram of the process flow of the P&A management server
`
`12 according to one embodiment” of Diacakis; in other words, the figure describes
`
`the main functionality and operation of the P&A server in Diacakis. Exhibit 1007
`
`at Fig. 5 and [0049]. The process shown in the figure and described in the
`
`corresponding text involves the processing of user profiles along with presence and
`
`availability information, and the distribution of availability information (including
`
`contact information, as explained above) to subscribers. The process provides no
`
`evidence whatsoever that the P&A server may initiate or carry out user-to-user
`
`communication as part of its functionality. Exhibit 1007 at Fig. 5 and [0049]-
`
`[0050].
`
`Figure 6 of Diacakis shows another embodiment of the P&A server that
`
`differs from the embodiments in Figs. 1 and 4 only in that it includes an adaptive
`
`feedback module 100. Exhibit 1007 at Figs. 1, 4, 6, and [0051]. “The adaptive
`
`feedback module 100 may determine whether the individual’s availability
`
`information is, for example, inaccurate or unusable” and hence this embodiment
`
`does not add any capabilities or functions for user-to-user communication. Exhibit
`
`1007 at [0052].
`
`
`
`20
`
`
`
`Figure 7 and the corresponding text describe the process flow of the P&A
`
`server according to the embodiment of Fig. 6. Exhibit 1007 at Figs. 6-7 and
`
`[0054]-[0055]. As with Fig. 5 above, the process of Fig. 7 is limited to the
`
`processing and distribution of presence and availability information based on user
`
`profiles and provides no teaching or even a hint that the P&A server is used for
`
`user-to-user communication. Id.
`
`As discussed above, Fig. 9 and the accompanying text expressly demonstrate
`
`that the indicator module 110 and user interface 112 only receive availability
`
`information from the P&A server, Exhibit 1007 at Fig. 9, [0063], [0068]. There is
`
`no teaching or indication that modules 110 or 112 are used to receive or send any
`
`user-to-user messages. Id.
`
`Figure 10 “is a diagram of the process flow through the indicator module
`
`110;” that is, the figure describes the functionality and operation of the indicator
`
`module 110. Exhibit 1007 at Fig. 10 and [0065]. Figure 10 and the corresponding
`
`text make clear that the indicator module 110 only receives, processes, and
`
`displays availability information including contact information, as explained
`
`earlier) of each individual to which the user subscribes. Exhibit 1007 at Fig. 10
`
`and [0065]-[0067]. Therefore, as explained above, the Diacakis indicator is not
`
`used to send or receive user-to-user messages.
`
`
`
`21
`
`
`
`Figure 11 is not an embodiment of a P&A server. The figure depicts client
`
`devices 22 and 140, relay hosts 142a and 142b, domain name servers 144 and 146,
`
`resolver 148, and IP address database 150, but no P&A server. Exhibit 1007 at Fig.
`
`11 and [0072]-[0076]. Therefore, Fig. 11 does not provide any teaching that the
`
`Diacakis P&A server and system is used for user-to-user communication. Id.
`
`Petitioner therefore failed to meet its burden of proof. 37 C.F.R. § 42.1(d); Practice
`
`Guide at 42.
`
`
`
`E.
`
`[7.8] Diacakis Teaches That Contact Information Is Provided
`
`The POR proves that Diacakis teaches a POSITA that contact information is
`
`provided. POR at 27-35. First, for the reasons set forth in the POR, the negative
`
`limitation of contact information not provided is inconsistent with an interpretation
`
`that the NBP is within the sender’s device in Diacakis. POR at 27-28. The
`
`unrebutted evidence shows that in Diacakis if the second user receives a message
`
`from the first user, the first user has the second user’s contact information to send
`
`the message. Id.
`
`
`
`Second, regarding Judge Chang’s opinion that Diacakis does not teach the
`
`negative limitation, the Reply asserts that “[n]either the POR nor the Rouskas
`
`Declaration provides any additional analysis or evidence related to those already-
`
`considered views.” Reply at 16. The POR and Rouskas Declaration did not exist at
`
`the time of the Institution Decision, so it was impossible for the arguments and
`
`
`
`22
`
`
`
`evidence set forth in the POR to have been “already-considered”. In fact, the
`
`Board recognized in its Institution Decision that it was not able to fully consider
`
`the PO’s position until the record is complete. Institution Decision at 19. Now that
`
`the POR has shown that Diacakis does not teach the negative limitation, the Board
`
`should agree with Judge Chang’s opinion and deny Ground I. Indeed, the POR’s
`
`evidence is unrebutted.
`
`
`
`Third, without any citation, or evidence from a POSITA, the Reply posits
`
`“the Diacakis system does not provide contact information simply because one
`
`user contacts another; rather, it determines whether or not to provide information
`
`subject to the recipient’s preferences.” Reply at 16. In contrast, the POR sets forth
`
`many unrebutted examples of Diacakis teaching that the contact information not
`
`only is provided, but is displayed to the user, including Figs. 2, 3, and 8. POR at
`
`29-32.
`
`
`
`That the server “takes into account [the recipient’s] preference setting for the
`
`subscriber’s access group” does not imply that the server “determines whether or
`
`not to provide information subject to the recipient’s preferences,” as Petitioner
`
`argues. Reply at 16. Rather, consistent with Diacakis’s teachings on “access
`
`groups”, the quoted sentence simply recognizes that if, say, the “Normal” access
`
`group does not have access to, e.g., the IM address, then the server will not provide
`
`
`
`23
`
`
`
`it; but will provide the telephone, voicemail, and email addresses to which the
`
`“Normal” group has access. Exhibit 1007 at [0032]-[0037] and Figs. 2, 3.
`
`
`
`Diacakis does not include any embodiment in which an access group is not
`
`provided any contact information but still can communicate with a recipient. All
`
`embodiments differentiate among access groups only in that each has access to
`
`different pieces of a recipient’s contact information. Exhibit 1007 at [0032]. In
`
`fact, Diacakis expressly defines a “Blocked access level” as “persons” who
`
`“receive not [sic] contact information at all.” Id. But persons in the “Blocked”
`
`level cannot contact the recipient. Therefore, Petitioner’s attorney argument that
`
`the Diacakis system allows a user who receives no contact information to
`
`communicate with a recipient is baseless and not supported by any POSITA
`
`evidence.
`
`
`
`Fourth, PO does not conflate two techniques that allow Diacakis’s users to
`
`control their interactions. Reply at 17. PO never claimed that Petitioner relies on
`
`the blocking feature of Diacakis. PO simply pointed out that Diacakis clearly
`
`teaches that only “blocked” persons receive no contact information and that
`
`“blocked” pers
