`

`IPR2017-00614
`Patent 6,975,719 B1
`
`
`LivePerson, Inc. (“Petitioner”) filed a Petition (Paper 1, “Pet.”)
`requesting inter partes review of claims 1–3, 20, and 46 of U.S. Patent No.
`6,975,719 B1 (Ex. 1001, “the ’719 patent”). Patent Owner 24/7 Customer,
`Inc. (“Patent Owner”) did not file a Preliminary Response.
`Pursuant to 35 U.S.C. § 314(a), an inter partes review may not be
`
`instituted unless “the information presented in the petition . . . and any
`response . . . shows that there is a reasonable likelihood that the petitioner
`would prevail with respect to at least 1 of the claims challenged in the
`petition.” For the reasons set forth below, we conclude that there is a
`reasonable likelihood that Petitioner would prevail in establishing the
`unpatentability of claims 1–3, 20, and 46. Therefore, we institute inter
`partes review of claims 1–3, 20, and 46.
`
`

`
`
`B. THE ’719 PATENT
`The ’719 patent is directed to a phone system with an integrated chat
`client service. Ex. 1001, Abstract. The Specification describes a need for a
`“mechanism by which a called party can keep his/her side of the
`conversation private from others who may be present in the room.” Id. at
`1:55–58. When a called party who is subscribed to an integrated chat client
`service receives a phone call, the system determines whether the caller has
`an accessible network-attached computer. Id. at 3:19–27. If they do, the
`system prompts the called party to determine whether to chat or talk with the
`calling party. Id. at 3:31–42. If the called party chooses to chat, the system
`sends a chat invitation to the calling party, and, if the calling party accepts, a
`chat session may be arranged. Id. at 3:46–56.
`C. CHALLENGED CLAIMS
`Petitioner challenges claims 1–3, 20, and 46. Independent claim 1 is
`
`reproduced below.
`1. A phone system, comprising:
`a first call processing system element operable to check a chat
`server for accessibility of a calling party chat client
`associated with a calling party; and
`a second call processing system element operable to prompt a
`called party to select to talk or chat.
`Ex. 1001, 8:41–47.
`Independent claim 2 includes the same elements as claim 1 and adds
`the following:
`wherein the first call processing system element includes a
`service control point operable to receive a query and to check a
`chat server for accessibility of a calling party chat client
`associated with a calling party, the chat server being coupled to
`the internet and the service control point; and wherein the
`3
`
`
`
`

`

`IPR2017-00614
`Patent 6,975,719 B1
`
`
`second call processing system element includes a service node
`coupled to the service control point and operable to prompt a
`called party to select either talk or chat.
`Id. at 8:49–64.
`Claim 3 depends from claim 2 and further requires the chat server to
`“send chat invitations to the calling party chat client and a called party chat
`client upon the called party selecting to chat with the calling party.” Id. at
`8:64–67.
`Independent claim 20 is a method claim that mirrors the limitations of
`claim 1. See id. at 9:66–10:4. Independent claim 46 is a computer readable
`medium claim that likewise mirrors the limitations of claim 1. See id. at
`12:7–13.
`
`D. ASSERTED GROUNDS OF UNPATENTABILITY
`Petitioner asserts the following grounds of unpatentability. Pet. 4.

`2 Although Petitioner characterizes this ground as one based on obviousness,
`in substance, Petitioner asserts Luehrig anticipates the challenged claims.
`See Pet. 16 (asserting that Luehrig “discloses, and at a minimum renders
`obvious, the alleged invention claimed by each of the Challenged Claims”);
`id. at 18–31 (not identifying any potential differences between claimed
`subject matter and Luehrig). We therefore treat Petitioner’s challenge as one
`based on anticipation, not obviousness.

`
`II. ANALYSIS
`A. CLAIM CONSTRUCTION
`Petitioner does not propose any claim constructions, and we conclude
`no express claim constructions are necessary for our determination of
`whether to institute inter partes review. 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.”).
`
`B. ASSERTED PRIOR ART
`
`1. Luehrig (Ex. 1004)
`Luehrig was filed on March 12, 2002, before the earliest priority date
`of the ʼ719 patent, and, on the present record, is prior art under 35 U.S.C.
`§ 102(e). Pet. 5. Luehrig addresses a method for facilitating mediated
`communication. Ex. 1004, Abstract. In Luehrig, a subscriber may accept or
`defer an inbound communication. Id. ¶ 0059. In particular, in response to
`receiving a request for voice-based communication, an operation is
`performed that offers an option of sending the caller a text-messaging based
`response. Id. ¶ 0118. When the called party selects this chat option, the
`system provides a “follow-through action,” such as sending a predefined text
`message. Id. ¶ 0120. According to Luehrig, “[t]he text messaging follow-
`through action enables the subscriber to initiate a notification to the calling
`device that a text messaging response to the request for voice-based
`communication is to be used.” Id.
`2. Truetken (Ex. 1002)
`Truetken was filed on March 29, 1999, before the earliest priority date
`of the ʼ719 patent, and, on the present record, is prior art under 35 U.S.C.
`
`
`

`
`

`

`IPR2017-00614
`Patent 6,975,719 B1
`
`§ 102(e). Pet. 5. Truetken teaches an Internet Protocol (“IP”) telephony
`client that initiates and manages multimedia sessions. Ex. 1002, Abstract.
`When a calling party initiates a call, the system prompts the calling party to
`select from a list of available helper applications or media types, including
`“IP phone, browser, e-mail, chat, personal directory, video streaming
`applications, and the like.” Id. at 4:2–4, 15–33. Once selected, a Session
`Initiation Protocol or “SIP” invite is sent to the called party, prompting the
`called party to accept, decline, or negotiate for other options. Id. at 4:41–47.
`In particular,
`if the called party wishes to negotiate for a different time or
`media for the call, the called party clicks on an other options
`button, which causes the called party client to open another
`options dialog box . . . . The options dialog box gives the called
`party the opportunity to suggest alternative media or an
`alternative time for the call. The called party client populates
`the options dialog box with the names of the other helper
`applications that the called party has available.
`Id. at 4:59–67. Once the calling and called parties have agreed on a
`communications medium, the appropriate helper application launches on the
`parties’ respective systems. See id. at 5:9–19, 58–60, Fig. 6.
`C. ASSERTED GROUNDS
`1. Ground 1: Anticipation Based on Luehrig (Ex. 1004)
`Petitioner asserts Luehrig anticipates claims 1–3, 20, and 46. Pet. 18–
`31. As explained below, based on this record and for purposes of this
`Decision, Petitioner has shown a reasonable likelihood of succeeding on its
`anticipation challenge to claims 1–3, 20, and 46 based on Luehrig.

`f. Conclusion
`Accordingly, for the reasons outlined above, we conclude that
`Petitioner has demonstrated a reasonable likelihood of prevailing on its
`challenge to claims 1–3, 20, and 46 as anticipated under 35 U.S.C. § 102(e)
`by Luehrig.
`2. Ground 2: Obviousness Based on Truetken (Ex. 1002) and Luehrig (Ex.
`1004)
`Petitioner contends claims 1–3, 20, and 46 would have been obvious
`over Truetken and Luehrig at the time of the invention. Pet. 31–45. As
`explained below, based on this record and for purposes of this Decision,
`Petitioner has shown a reasonable likelihood of succeeding on its
`obviousness challenge to claims 1–3, 20, and 46 based on Truetken and
`Luehrig.
`a. Independent Claim 1
`Petitioner has made an adequate showing that the combination of
`Truetken and Luehrig teaches “[a] phone system, comprising a first call
`processing system element operable to check a chat server for accessibility
`of a calling party chat client associated with a calling party.” See Pet. 33–36
`(citing Ex. 1002, Abstract, 1:34–39, 1:51–55, 2:53–55, 4:2–4, 4:15–33,

`
`
`f. Rationale for Combining Truetken and Luehrig
`In addition, based on this record and for purposes of this Decision,
`Petitioner made a sufficient showing that one skilled in the art would have
`reason to combine the known elements in the manner Petitioner suggests.
`See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). The Petition
`explains, with relevant support from Petitioner’s Declarant, that it would
`have been obvious for one skilled in the art to combine Truetken with
`Luehrig because “Truetken provides a prompt dialog user interface and
`invitation-based negotiation methods for connecting parties through various
`communications media” while “Luehrig provides additional methods that a
`person of ordinary skill in the art would understand could streamline and
`increase the efficiency of the Truetken method.” Pet. 32 (citing Ex. 1005
`¶ 83). Petitioner explains also that “Luehrig teaches the advantage of
`determining whether the calling party has text chat capabilities prior to
`prompting the called party whether to talk or chat, thereby eliminating the
`problem of Truetken in which a suggested communications medium may be
`unavailable to the other party.” Id. at 32–33. Thus, as Petitioner explains,
`one skilled in the art “would be further motivated to include this
`improvement from Luehrig in the system of Truetken because it would
`increase the likelihood of a successful negotiation for a desired
`communications medium, and reduce the overhead involved in multi-step
`negotiations.” Id. at 33 (citing Ex. 1005 ¶¶ 82–84).
`g. Conclusion
`Based on the analysis above, we find Petitioner has made an adequate
`showing that the combination of Truetken and Luehrig teaches or suggests
`each limitation in claims 1–3, 20, and 46, and articulated an adequate
`
`
`
`12
`
`

`

`IPR2017-00614
`Patent 6,975,719 B1
`
`rationale explaining why one skilled in the art would have combined
`Truetken and Luehrig in the manner Petitioner proposes. Thus, on the
`current record and for purposes of this Decision, we determine that
`Petitioner has set forth a reasonable likelihood of succeeding on its
`obviousness challenge to claims 1–3, 20 and 46.
`
`III. CONCLUSION
`For the foregoing reasons, we determine that the information
`presented in the Petition establishes a reasonable likelihood that Petitioner
`would prevail in showing claims 1–3, 20, and 46 unpatentable. Any
`discussion of facts in this Decision is only for the purposes of institution and
`is not dispositive of any issue related to any ground on which we institute
`review. We note that Patent Owner has not, at this stage of the proceeding,
`addressed Petitioner’s analysis and supporting evidence. The Board’s final
`determination will be based on the record as fully developed during trial.
`
