`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`I, Dr. Leonard J. Forys, declare as follows:
`
`1.
`
`This declaration supplements my declaration (Ex. 1003) submitted
`
`with Apple’s Petition in IPR2017-00222. For the sake of brevity, I rely on and
`
`confirm the facts and opinions contained in my Declaration dated November 14,
`
`2016 – Ex. 1003. My qualifications and background information can be found in
`
`my original Declaration. (Ex. 1003 ¶¶1-2, 6-53.)
`
`2.
`
`I am making this declaration to respond to certain arguments raised by
`
`Uniloc USA Inc. and Uniloc Luxembourg S.A., (“Uniloc” or “PO”) in its Patent
`
`Owner Response (“POR”) and the declaration of William C. Easttom II (Ex.
`
`2001) submitted therewith. In view of Uniloc’s and Mr. Easttom’s arguments, it is
`
`still my opinion that all of the claim elements in the ’723 patent are taught or
`
`suggested by Vuori alone or in combination with Malik and the other prior art
`
`references presented in the Grounds of the Petition. In my opinion, Uniloc’s
`
`arguments rely on overly narrow interpretations of the claim elements, inaccurate
`
`explanations of the prior art references, and unfounded concerns about the
`
`combinations of prior art references that inflate potential “detriments” and ignore
`
`an artisan’s understanding of design tradeoffs. My opinions are set forth below.

`
`
`II. Response to Uniloc’s Patent Owner Response and Mr. Easttom’s
`Declaration
`
`6.
`
`I address certain portions of Uniloc’s POR and Mr. Easttom’s
`
`Declaration below. Failure to address any statement or argument presented by
`
`Uniloc or Mr. Easttom should not be viewed as an acquiescence to or agreement
`
`with that statement or argument.
`
`A. The term “list” means a list of “one or more nodes.”
`As I mentioned in my original Declaration, I have applied the plain
`7.
`
`and ordinary meaning of the claim terms as understood to a POSITA at the time of
`
`invention. (Ex. 1003, ¶101.) Uniloc’s attempt to limit the term “list,” as recited in
`
`claim 1, to “more than one,” is inconsistent with the plain and ordinary meaning
`
`of the term “list.” In fact, Uniloc’s proposed definition is well outside what a
`
`POSITA would have understood the term to mean in light of the specification.
`
`Further, Mr. Easttom’s analysis, hinges on the faulty construction, which is
`
`divorced from the plain and ordinary meaning of the terms at issue.
`
`8.
`
`The recited “list” includes the recorded connectivity status of one or
`
`more nodes. The Board stated:
`
`Patent Owner’s argument appears to take an overly narrow view of
`the term to mean that the ‘list of the recorded connectivity status’
`must include the connectivity status of more than one node. Patent
`Owner cites no factual support in the record for its argument that the
`scope of the term excludes a singular value. Furthermore, based on
`
`
`
`- 5 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`our review of the ’723 patent, the specification seems to contradict
`Patent Owner’s argument.
`
`(Institution Decision, 17-18, emphasis added.)
`
`9.
`
`Based on the ’723 specification, the term “list” must include the
`
`connectivity status of “one or more nodes.”
`
`10. Uniloc argues that “[a] plain reading of the claim language itself …
`
`unambiguously resolves this issue” and that without the “modifying phrase ‘one
`
`or more’… the transmitted ‘list’ must have the recorded connectivity status for
`
`multiple ‘nodes’” (POR, 8-9.) This fails to take into account that the ’723 patent
`
`specification consistently refers to a list as having “one or more” items: “a list of
`
`one or more IVM recipients” (’723 patent, 8:52-56 and 16:61-63) and “[t]he IVM
`
`client 208 displays a list of one or more IVM recipients on its display 216,
`
`provided and stored by the local IVM server 202” (Institution Decision, citing
`
`’723 patent, 7:61-63). So a POSITA would have understood that a “list” in this
`
`patent, under its broadest reasonable interpretation (BRI), encompasses “one or
`
`more” items.
`
`11.
`
`In addition to being overly narrow, Uniloc’s analysis is incomplete.
`
`For example, Uniloc argues that the omission of the modifying phrase “one or
`
`more” confirms that “the transmitted ‘list’ must have the recorded connectivity
`
`status for multiple ‘nodes.’” (POR, 9.) Uniloc’s analysis fails to identify other
`
`
`
`- 6 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`modifying phrases that are also omitted from the claim. For example, if the ’723
`
`patent inventor truly intended the transmitted list to include the recorded
`
`connectivity status for “multiple nodes,” as Uniloc argues, notably missing from
`
`the claim language are phrases including “more than one” or “a plurality of...”
`
`12. Because under the Patent Owner’s argument the claim is ambiguous
`
`and does not define the term “list” with a modifying phrase, the term must be
`
`interpreted according to its BRI in light of the specification.
`
`13. Uniloc further argues that, “[v]iewing Claim 1 as a whole further
`
`confirms that the phrase ‘one or more’ was explicitly recited when the intent was
`
`to encompass both the singular and plural form of a term.” (POR, p. 8.) Uniloc’s
`
`analysis is, again, incomplete. Looking at claim 1 as a whole, and even just the
`
`limitation as a whole, reveals that the claim recites the phase “a list of the
`
`connectivity status of each of the nodes in the sub-set.” The term sub-set is not
`
`defined by the ’723 patent, but a POSITA would have understood that the term
`
`sub-set means a smaller part of larger set. That is, a POSITA would have
`
`understood that the “sub-set of nodes” could be a single node. In such a case, the
`
`list of “the connectivity status of each of the nodes in the sub-set” could
`
`reasonably include only one node, because the sub-set contains only one node.
`
`Thus, under BRI the term “list” must include the connectivity status of “one or
`
`more nodes.” The Uniloc position would not consider a network composed of
`
`
`
`- 7 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`only two subscribers as being within the scope of the claims. However, nothing in
`
`the ‘723 patent prohibits such a situation.
`
`14. Finally, Uniloc provides that “[i]t is significant that ‘nodes’ is recited
`
`in the plural in the phrase ‘each of the nodes in the sub-set.’ Use of the plural form
`
`of ‘nodes’ in that context confirms the ‘list’ must record the connectivity status of
`
`more than one node.” (POR, 8.) Yet the specification refers to a list as having
`
`“one or more” items – and in each case the “one or more” items are identified in
`
`plural form. Thus, Uniloc’s argument falls short because the recitation of nodes
`
`(in plural form) is consistent with the ’723 patent’s disclosure of a “list of one or
`
`more” items (in plural form).
`
`15.
`
`In view of the foregoing, the term “list” encompasses “one or more.”
`
`B. Vuori’s SVM watcher is user-facing, therefore Vuori teaches or
`suggests “transmitting a signal to a client including a list of the
`recorded connectivity status…”
`
`16. Mr. Easttom argued that Vuori’s “SVM watcher 256 is not a user-
`
`facing ‘client’ and thus does render obvious the claimed ‘transmitting’ step.”
`
`(POR, 12; Ex. 2001, ¶29.) But Vuori’s SVM watcher is user-facing and does
`
`distribute connectivity status on a line to the user. The directional arrows of
`
`Vuori’s Figure 7 are not dispositive, Vuori expressly
`
`teaches two-way
`
`communication. Vuori teaches that a user interacts with the system using an
`
`SVM watcher UA, suggesting two-way communication. Vuori further teaches that
`
`
`
`- 8 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`“[a] user agent is purely coupling between a principal and some core entity of
`
`the system” including the SVM watcher 256. The term coupling, as applied in
`
`Vuori, indicates that the SVM watcher is coupled to the user agent, suggesting
`
`that the SVM watcher is indeed user-facing. The presence status is distributed so
`
`that it can be “interpretable by programs or by persons,” suggesting a person
`
`may view and thus interpret shared presence status information. Vuori’s
`
`description of a buddy list is evidence that the SVM watcher is user-facing
`
`because the sender determines whether the intended recipient is available by
`
`means of a presence service. Each of the foregoing reasons is evidence that
`
`Uniloc’s arguments fall short.
`
`17. Uniloc appears to argue that the arrows of Figure 7 indicate that the
`
`presence information is distributed only to the SVM watcher 256 and is not
`
`distributed to a “‘user agent’ or ‘UA’ device (276, 278) of either end user.” (POR,
`
`12.) Uniloc’s reliance on the “directional communication arrows in Figure 7” fails
`
`to consider Vuori’s entire disclosure. A POSITA would have understood that the
`
`direction of the arrows illustrated in the Figure are not dispositive and do not
`
`exemplify the only embodiments described in Vuori.
`
`18. Vuori’s SVM watcher is further illustrated in Figure 8.
`

`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`
`“As shown in FIG. 8, according to an adaptation of RFC 2778, there
`are two kinds of SVM watchers, called SVM fetchers 258 and SVM
`subscribers 260. An SVM fetcher 258 simply requests the current
`value of some SVM presentity's presence information from the
`presence service 248. In contrast, an SVM subscriber 260 requests
`notification from the SVM presence service 248 of (future) changes in
`some SVM presentity's presence information. A special kind of SVM
`fetcher is one that fetches SVM presence information on a regular
`basis. This is called an SVM poller 262.”
`
`(Vuori, [0044], emphasis added.) As is known in the art, “requesting,” “fetching,”
`
`and “polling” are done by sending messages from a device 258 (SVM Watcher) to
`
`device 248 (SVM presence service), thus in the opposite direction from the
`
`indicated arrow in Figure 7. Thus, because Vuori’s SVM watchers are capable of
`
`requesting, fetching, and polling information, it suggests two-way communication
`
`and/or data transfer. That is the plain and ordinary meaning of the term “interact.”
`
`And the SVM watcher’s requesting, fetching, and polling information show that
`
`the arrows of Figure 7 are not dispositive, as Mr. Easttom seems to suggest.
`
`
`
`- 10 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`19. Figure 7 shows each user agent is associated with a principal. As
`
`described in Vuori, the term “principal” refers to “people, groups and/or software
`
`in the ‘real world’ outside of the system that use the system as a means of
`
`coordination and communication.… A principal interacts with the system via one
`
`of several user agents (UAs) such as shown in FIGS. 7 and 9.” (Vuori, [0046].)
`
`Vuori therefore suggests that when a principal interacts with the system via a user
`
`agent, he/she is engaging in a two-way communication and/or data transfer –
`
`because that is the plain and ordinary meaning of the term “interact.” Thus, a
`
`POSITA would have understood that the described interaction indicates that the
`
`SVM watchers are user-facing because data, including connectivity information,
`
`may be distributed to and from the user agents via the described interaction.
`
`20. Vuori further teaches that “[a] user agent is purely coupling between a
`
`principal and some core entity of the system (SVM inbox 274, SVM sender 272,
`
`SVM presentity 254, SVM watcher 256). It will therefore be understood that the
`
`simple examples shown in RFC 2778 are applicable to the SVM service of the
`
`present invention.” (Vuori, [0046].) The term coupling, as applied in Vuori,
`
`indicates that the SVM watcher is “coupled” to the user agent. When two entities
`
`are coupled, as the user agent and SVM watcher 256, a POSITA would
`
`understand that the disclosed coupling suggests a two-way communication
`
`
`
`- 11 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`between the user agent and SVM watcher 256. Thus, Vuori teaches or suggests
`
`that the SVM watcher is indeed user-facing.
`
`21. Evidence that the SVM watcher is indeed user-facing, and that Mr.
`
`Easttom’s conclusions are misguided, can be found in Vuori’s description of the
`
`term “status.” For example, Vuori teaches that each “element comprises a status
`
`marker 298, 300 (which might convey information such as on-line/off-
`
`line/busy/away/do not disturb).… Status can be interpretable by programs or by
`
`persons and can consist of single or multiple values as spelled out in the IETF
`
`model of RFC 2778.” (Vuori, [0047], emphasis added.) For status information to
`
`be interpretable by a person, the status information must be transmitted to a device
`
`capable of, e.g., displaying the information (or otherwise informing them) for the
`
`person to see. Thus, Vuori discloses or suggests that the status (i.e. connectivity)
`
`information is available to a person and that the SVM watcher is user-facing.
`
`22. The term “buddy list” was a well-known term in the art. Vuori
`
`describes the term buddy list in the context of a sender determining whether or not
`
`the potential recipient is available to receive a message. (See Vuori [0035]).
`
`Specifically, “the sender first determines whether the intended recipient is
`
`available by means of a presence service and the intended recipient has
`
`effectively acquiesced to availability by previously joining a ‘buddy list’ or
`
`otherwise subscribing to the service.” The first thing to note is that the term
`
`
`
`- 12 -
`
`
`
`
`
`
`
`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`“buddy list” is in quotations which suggest that it is a term of art. The applicant
`
`provides “joining a ‘buddy list’” as an example for subscribing to a presence
`
`service. Vuori’s presence service
`
`tracks presence
`
`information
`
`including
`
`information such as whether a user is on-line/off-line/busy/away/do not disturb.
`
`(Vuori, [0047].) So a sender is able to determine whether an intended recipient is
`
`available because the recipient has acquiesced to availability by previously joining
`
`a buddy list. That is, the connectivity information of a potential recipient
`
`connected to the network is distributed to the sender. (Vuori, [0035] and [0047].)
`
`23. Vuori additionally teaches:
`
`An SVM presence service 248 serves to accept SVM presence
`information e.g. on a line 250, store it, and distribute it, e.g., on a
`line 252. An SVM presentity 254 is a client that provides the presence
`information on the line 250 to be stored and distributed. Another set
`of clients called SVM watchers such as an SVM watcher 256 in FIG.
`7, receives SVM presence information on the line 252 from the SVM
`presence service 248.
`
`(Id., [0043], emphasis added.)
`
`24. Again, according to Vuori, when a user joins a buddy list, he/she
`
`acquiesces in their availability information being shared with others, using, for
`
`example, Vuori’s presence service. Thus, a user’s availability is stored and
`
`distributed to the clients associated with the buddy list that the potential recipient
`
`has joined. A POSITA would have understood that by joining a “buddy list,” a

`
`user allows his/her presence information (i.e. connectivity) to be transmitted to all
`
`of the nodes associated with the buddy lists he/she has joined. (Ex. 2002, Forys
`
`Deposition, 73:7-11.) That is, the “buddy list” is not a list belonging to the
`
`recipient, but rather it belongs to the sender who is able to see which recipients are
`
`available.
`
`25. A POSITA would have understood that Vuori’s SVM watcher is user-
`
`facing and that Vuori teaches distributing the presence information because, as the
`
`Board agreed, “[d]istributing connectivity information ‘on a line’ means to
`
`distribute the information to other users connected to the network,” as recited in
`
`claim 1. (Institution Decision, 17-18.)
`
`26. Even if the Board determines that the term “list” requires connectivity
`
`status of more than one node, a POSITA would have understood that Vuori still
`
`teaches the “transmitting” feature of claim 1, including a “list of the recorded
`
`connectivity status for each of the nodes in the sub-set corresponding to the
`
`client.” For example, Vuori determines the availability of one or more recipients,
`
`and “[t]he user 10 then uses the menu key to select one or more intended
`
`recipients…” (Vuori, [0033].) And “[t]he SVM is then sent to an SVM service
`
`center. This could be a short message service (SMS) service center which
`
`determines the availability of the one or more intended recipients.” (Vuori,
`
`[0034].) To the extent Uniloc or Mr. Easttom may argue that the short message

`
`service center is different than, or does not include, Vuori’s presence service, a
`
`POSITA would apply the foregoing teachings (i.e., determining the availability of
`
`one or more intended recipients) to the presence service.

`Case IPR2017-00222
`U.S. Pat. No. 8,243,723
`
`
`
`
`filed as evidence in a contested case before the Patent Trial and Appeal Board of
`
`the United States Patent and Trademark Office. I also recognize that I may be
`
`subject to cross-examination in the case and that cross-examination will take place
`
`within the United States. If cross-examination is required of me, I will appear for
`
`cross-examination within the United States during the time allotted for cross-
`
`examination.
