`Petition for Inter Partes Review of
`U.S. Patent No. 8,724,622
`
`This is a petition for Inter Partes Review of claims 3, 6-8, 10, 11, 13, 14-23,
`
`27-35, 38, and 39 of U.S. Patent No. 8,724,622 (Ex. 1001) (“’622 patent”).
`
`I. MANDATORY NOTICES UNDER 37 C.F.R. § 42.8(A)(1)
`A. Real Party-In-Interest under 37 C.F.R. § 42.8(b)(1)
`Facebook, Inc. and WhatsApp Inc. (“Petitioners”) are the real parties-in-
`
`interest to this inter partes review petition.
`
`B. Related Matters under 37 C.F.R. § 42.8(b)(2)
`The ’622 patent was the subject of two requests for inter partes review
`
`(IPR2017-00223 and IPR2017-00224) filed by Apple Inc. on November 14, 2016,
`
`which were denied by the Board on May 25, 2017. The Petitioners herein were not
`
`parties to and did not participate in the preparation of those petitions.
`
`Concurrent with the filing of this Petition, the Petitioners are filing a second
`
`petition for inter partes review to address claims not covered by the present Petition.
`
`More specifically, the present Petition addresses claims 3, 6-8, 10, 11, 13, 14-23, 27-
`
`35, 38, and 39, whereas the other petition addresses claims 4, 5, 12, and 24-26. The
`
`Petitioners filed their challenges against these claims in two separate petitions to
`
`provide a more complete and thorough treatment of each claim.
`
`The ’622 patent is also the subject of two pending litigations involving the
`
`Petitioners: Uniloc USA, Inc. et al. v. Facebook, Inc., Case No. 2:16-cv-00728-JRG
`
`(E.D. Tex. filed July 5, 2016 and served July 11, 2016) and Uniloc USA, Inc. et al.

`
`Uniloc USA, Inc. et al. v. Samsung Electronics America, Inc., Case No. 2:16-cv-
`
`00642-JRG (E.D. Tex.). These petitions are timely under the one year statute of
`
`limitations in 35 U.S.C. § 315(b). Currently, these litigations are stayed pending the
`
`outcome of IPR petitions filed by third party Apple Inc.
`
`The Petitioners are also aware of the following additional pending litigations
`
`involving the ’622 patent: Uniloc USA, Inc. et al. v. Apple Inc., Case No. 2:16-cv-
`

`
`the Petitioners are not parties to those other litigations, because they involve
`
`allegations of infringement of the ’622 patent, they may be impacted by a decision
`
`by the Board in this IPR proceeding.

`
`Part VI below explains why the challenged claims are unpatentable based on
`
`these grounds. These references were not cited during the original ’622 patent
`
`prosecution, and were not cited in the separate IPR petitions filed by Apple Inc.
`
`(IPR2017-00223 and IPR2017-00224) that were denied by the Board on May 25,
`
`2017. Submitted with the Petition is the Declaration of Tal Lavian, Ph.D. (Exhibit

`
`Ex. 1002, ¶¶1-10, Ex. A.)
`
`IV. PERSON OF ORDINARY SKILL IN THE ART
`As Dr. Lavian explains, a person of ordinary skill in the art for purposes of
`
`the ’622 patent would have possessed at least a bachelor’s degree in computer
`
`science, computer engineering, or electrical engineering with at least two years of
`
`experience in development and programming relating to network communication
`
`systems (or equivalent degree or experience). (Lavian, ¶¶13-15.)
`
`V. CLAIM CONSTRUCTION UNDER 37 C.F.R. § 42.104(B)(3)
`“instant voice messaging application”
`A.
`The broadest reasonable interpretation of an “instant voice messaging
`
`application” in the context of the claims of the ’622 patent is “hardware and/or
`
`software used for instant voice messaging.” (Lavian, ¶¶49-57.)1
`
`The written description does not use the word “application” in any way
`
`relevant to the alleged invention. The word “application” appears in the written
`
`
`1 The Petitioners do not contend that any term herein, under its broadest reasonable
`
`construction, is a “means-plus-function” element subject to 35 U.S.C. § 112, ¶6 (pre-
`
`AIA). The Petitioners reserve their right to argue that terms are indefinite under
`
`narrower litigation claim construction standards.
`
`
`
`
`
`-6-

`

`
`description solely in reference to related patent applications. (’622, 1:4-14.) The
`
`term “application” to a person of ordinary skill in the art typically refers to computer
`
`software for performing a particular function. (Lavian, ¶53.) But the written
`
`description of the ’622 patent indicates that the term “instant voice messaging
`
`application” should not be limited to software.
`
`The written description does not identify any particular software program
`
`capable of performing all of the functions associated with the “instant voice
`
`messaging application” recited in the claims. (Id., ¶54.) To the contrary, the patent
`
`describes these functions as being performed by an instant voice messaging (“IVM”)
`
`client, IVM client 208, which is a “general-purpose programmable computer.”
`
`(’622, 12:11-14.) Figure 3, an excerpt of which is reproduced below, shows these
`
`various boxes inside IVM client 208 (shown in annotated red box).
`
`
`
`
`
`-7-
`
`
`
`
`
`Petition for Inter Partes Review of
`U.S. Patent No. 8,724,622
`
`
`
`(Id., Fig. 3 (annotation added).) IVM client 208 in Figure 3 above contains client
`
`platform 302 and messaging system 320. (Id., 12:17-21; 12:6-11.)
`
`Claims 27 and 38 recite an “instant voice messaging application” that
`
`includes a “client platform system” and a “messaging system,” which correspond
`
`to the two components of the IVM client 208 from Figure 3 above. This
`
`correspondence indicates that the ’622 patent equates the claimed “instant voice
`
`messaging application” with the IVM client 208 which, as noted above, is a general-
`
`purpose computer. (’622, 12:11-14.) Accordingly, “instant voice messaging
`
`
`
`
`-8-
`
`
`
`
`
`Petition for Inter Partes Review of
`U.S. Patent No. 8,724,622
`
`application” should not under its broadest reasonable construction be limited to
`
`software. (Lavian, ¶¶55, 56.) The broadest reasonable interpretation of “instant
`
`voice messaging application” is “hardware and/or software used for instant
`
`voice messaging.” (Id. ¶57.)
`
`“client platform system”
`B.
`As noted in the preceding section, one component of the claimed “instant
`
`voice messaging application” is a “client platform system.” In particular, claims
`
`27 and 38 state that the “instant voice messaging application” includes “a client
`
`platform system for generating an instant voice message.” As shown below, the
`
`broadest reasonable construction of “client platform system” is “hardware and/or
`
`software on a client for generating an instant voice message.” (Lavian, ¶¶58-62.)
`
`The written description does not use the term “client platform system” but
`
`describes “client platform 302” whose purpose is “generating an instant voice
`
`message.” (’622, 12:7-8.) The written description further states that the client
`
`platform 302 “comprises a client engine 304, which controls other components” such
`
`as the document handler, file manager, and encryption/decryption. (Id., 12:17-21.)
`
`The written description does not identify what “client engine 304” actually is, e.g.,
`
`whether it is hardware and/or software. The written description instead provides a
`
`functional description of client engine 304 as performing at least two functions: (1)
`
`communicating with the server and (2) performing operations required to generate
`
`
`
`
`
`-9-
`
`
`
`
`
`Petition for Inter Partes Review of
`U.S. Patent No. 8,724,622
`
`an instant voice message. (Id., 12:24-25, 13:15-28.) Figure 3 similarly shows client
`
`engine 304 as a nondescript box within client platform 302. (Id., Fig. 3.)
`
`As explained above, the claimed “instant voice messaging application” is
`
`composed of hardware and/or software under its broadest reasonable construction.
`
`Because the claimed “client platform system” is part of the “instant messaging
`
`application,” the “client platform system” under its broadest reasonable construction
`
`should similarly not be limited to software. Accordingly, “client platform system”
`
`under its broadest reasonable construction is “hardware and/or software on a
`
`client for generating an instant voice message.” (Lavian, ¶¶61-62.)
`
`“communication platform system”
`C.
`Claim 3 recites “a communication platform system maintaining connection
`
`information for each of the plurality of instant voice message client systems
`
`indicating whether there is a current connection to each of the plurality of instant
`
`voice message client systems.”2 The specification describes the “communication
`
`platform” as being a part of the IVM server 202. (Lavian, ¶¶64-65 (citing ’622,
`
`13:46-55, Fig. 4 (item 402).) Accordingly, the broadest reasonable construction of
`
`this term is a “system of the server which relays communications and/or tracks

`
`appearing in this Petition has been added for emphasis.

`
`client connection information,” which is consistent with the function of the
`
`communication platform system recited in the claim. (Lavian, ¶¶63-65.)
`
`VI. THE CHALLENGED CLAIMS ARE UNPATENTABLE
`The challenged claims are unpatentable based on the grounds identified in
`
`Part III.B above. This Petition will first provide an overview of each reference and
`
`then describe the proposed grounds in detail.
`
`A. Brief Summary and Date Qualification of the Prior Art
` Overview of Zydney (Ex. 1003)
`Zydney is a published PCT application that describes a system for voice
`
`communication that enables a user to send instant voice messages, which Zydney
`
`calls “voice containers.” (Zydney, Ex. 1003, 2:2-3.) The system transmits the voice
`
`containers “instantaneously or stored for later delivery,” depending on whether or
`
`not the recipient is currently online. (Id., 1:19-22, 15:8-21.) Zydney qualifies as
`
`prior art under 35 U.S.C. § 102(b) (pre-AIA).
`
`The Petitioners also note that Zydney contains page numbers but not line
`
`numbers. For convenience and ease of reference, Exhibit 1003 contains a copy of
`
`Zydney in which line numbers have been added to the left of each page (beginning
`
`on page 1), to facilitate precise citation. Any citations to line numbers of Zydney in
`
`this Petition and in the Lavian Declaration, therefore, refer to those added line
`
`
`
`
`
`-11-

`
`numbers. A copy of the original Zydney reference without line numbers is submitted
`
`as Exhibit 1013.
`
`The system of Zydney is generally shown in Figure 1A, reproduced below.
`
`
`
`(Zydney, Fig. 1A (highlighting added).)
`
`Three key components of the system include the “SENDER PC SOFTWARE
`
`AGENT” shown on the left (22), the “RECIPIENT PC SOFTWARE AGENT”
`
`shown on the right (28), and the “CENTRAL SERVER” shown in the middle (24)
`
`-12-
`
`
`
`
`
`
`Petition for Inter Partes Review of
`U.S. Patent No. 8,724,622
`
`of Figure 1A. (Id., 10:19-11:1.) Zydney explains that the sender and recipient
`
`software agents may work on any suitable client device such as “a personal
`
`computer, wireless handheld computer such a personal data assistant (PDA), digital
`
`telephone, or beeper.” (Id., 11:14-20.) Central server (24) facilitates instant voice
`
`messaging between the sender and the recipient. (Id., 10:20-11:1.) The sender,
`
`recipient, and central server communicate with each other using a communications
`
`network, as shown with the bottom cloud labeled “INTERNET” in Figure 1A. (Id.,
`
`Fig. 1A; see also id., 5:4-5, 5:15-18, 10:11-14, 14:2-5.)
`
`Sending an instant voice message from a sender to a recipient in Zydney is
`
`straightforward. A message sender (originator) “selects one or more intended
`
`recipients from a list of names that have been previously entered into the software
`
`agent.” (Id., 14:17-19.) The sender also “digitally records messages for one or more
`
`recipients using a microphone-equipped device and the software age
