`IPR of U.S. Patent No. 8,199,747
`Google Inc. (“Petitioner”) petitions for Inter Partes Review (“IPR”) of
`
`claims 1-15 of U.S. Patent No. 8,199,747 (“the ’747 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)
`Google Inc. is the Petitioner. Google is a real party-in-interest in this
`
`proceeding, along with Motorola Mobility LLC, Huawei Device Co., Ltd., Huawei
`
`Device USA, Inc., Huawei Investment & Holding Co., Ltd., Huawei Technologies
`
`Co., Ltd., and Huawei Device (Dongguan) Co., Ltd.
`
`B. Related Matters Under 37 C.F.R. § 42.8(b)(2)
`Patent Owner filed a complaint on September 6, 2016 in the U.S. District
`
`Court for the Eastern District of Texas (Case No. 2:16-cv-992) alleging that
`
`Motorola Mobility LLC infringed the ’747 patent. The complaint was served on
`
`September 13, 2016. Patent Owner also filed a complaint on September 6, 2016
`
`(Case No. 2:16-cv-994) alleging that Huawei Device USA, Inc. and Huawei
`
`Technologies USA, Inc. infringed the ’747 patent (the complaint was also served
`
`on September 13, 2016). On October 6, 2016, Patent Owner filed an amended
`
`complaint, which eliminated Huawei Technologies USA, Inc. as a defendant and
`
`added Huawei Device Co., LTD., as a defendant.
`
`Patent Owner filed subsequent complaints in the Eastern District of Texas
`
`(Case Nos. 2:17-cv-231 and 2:17-cv-214) alleging that Google infringed the ’747
`
`patent.

`III. GROUNDS FOR STANDING AND CHALLENGE UNDER 37
`C.F.R. § 42.104
`A. Grounds for Standing Under 37 C.F.R. § 42.104(a)
`Petitioner certifies that the ’747 patent is available for IPR and Petitioner is
`
`not barred or estopped from requesting IPR.
`
`B. Challenge Under 37 C.F.R. § 42.104(b) and Relief
`Requested
`Petitioner requests IPR of claims 1-15 on the grounds listed below. A
`
`declaration from Dr. Paul S. Min, Ph.D. is also included in support of this Petition.
`
`Ground
`
`Claims
`
`Basis for Rejection
`
`Ground 1 1-6, 8, 12-13 Anticipated by Zydney
`
`Ground 2 2-6, 8, 12-13 Obvious over Zydney in view of Gralla
`
`Ground 3 7, 9-11, 14-15 Obvious over Zydney in view of Gralla and Okano
`
`Ground 4 7, 10
`
`Obvious over Zydney in view of Gralla and
`
`Erekson
`
`
`Zydney (GOOGLE1004), Okano (GOOGLE1006), and Erekson
`
`(GOOGLE1007) each qualify as prior art under 35 U.S.C. §102(b) because they
`
`were published over a year before the alleged priority date (December 18, 2003) of
`
`the ’747 Patent. Gralla (GOOGLE1005) provides a first printing date of
`
`“September 2001” from the book publisher. GOOGLE1005, 7; Ford Motor Co. v.
`

`
`
`
`Attorney Docket No. 19473-0373IP1

`Cruise Control Techs. LLC, IPR2014-00291, Paper 44 at 8 (PTAB June 29, 2015);
`
`Microsoft Corp. v. Corel Software, IPR2016-01086, Paper 14 at 9 (PTAB Dec. 1,
`
`2016) (“a book publisher is generally in business to publish books and to make
`
`them widely accessible to the public for purchase”). Gralla’s pre-2003 publication
`
`is corroborated by: the library record (GOOGLE1008) associated with Gralla’s
`
`Library of Congress Catalog Card Number, which identifies a publication date of
`
`2002, Gralla’s Copyright registration date of 2002 (GOOGLE1009), Gralla’s ISBN
`
`listing (GOOGLE1010), which identifies a publication date of 2001, and the
`
`product record maintained on the publisher’s website (GOOGLE1011), which
`
`claims publication occurred in 2001. Also, testimonial evidence in this record
`
`further corroborates that Gralla was publicly available at least as early as February
`
`of 2002. GOOGLE1012. Thus, Gralla undoubtedly qualifies as prior art under 35
`
`U.S.C §§102(a) and 102(b).
`
`None of the above-identified references were cited during the prosecution of
`
`the ’747 patent.
`
`This Petition is not duplicative or substantially similar to earlier IPR
`
`petitions challenging the ’747 patent. First, while other IPR petitions rely on
`
`Zydney to challenge a certain subset of the ’747 patent’s claims, the present
`
`Petition challenges all claims of the ’747 patent. Thus, Petitioner respectfully
`
`submits that any Patent Owner argument suggesting that the Board exercise its
`
`7
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`discretion to deny institution because other IPR Petitions challenge the ’747 patent
`
`using Zydney would unfairly allow Patent Owner to use those challenges “as a
`
`shield to considering whether additional claims are also [unpatentable].” Fitbit,
`
`Inc., v. BodyMedia, Inc., IPR2016-00545, Paper 8 at 8 (PTAB Aug. 8, 2016); see
`
`also Ford Motor Company, v. Paice LLC et al., IPR2015-00606, Paper 14 at 8
`
`(PTAB Nov. 9, 2015); see also Ford Motor Company, v. Paice LLC et al.,
`
`IPR2015-00792, Paper 13 at (PTAB Oct. 26, 2015). Second, Google is not a party
`
`to any of the earlier IPR proceedings against the ’747 patent and was only recently
`
`named in a complaint filed by Patent Owner alleging infringement of the ’747
`
`patent. Supra, Section II. Google’s due process rights and its interest in having a
`
`fair opportunity to be heard on the merits in this forum weigh heavily against any
`
`exercise of discretion to deny institution. Indeed, the Board has frequently
`
`recognized that independent proceedings are often warranted when different
`
`petitioners are involved. Sony Mobile Communications (USA) Inc., v. E-Watch,
`
`Inc., IPR2015-00402, Paper 7 at 6 (PTAB July 1, 2015); Apple Inc., v. E-Watch,
`
`Inc., IPR2015-00414, Paper 13 at 8 (July 1, 2015).
`
`IV. SUMMARY OF THE ’747 PATENT
`A. Brief Description
`The ’747 patent is directed to “an instant voice messaging system for
`
`delivering instant messages over a packet-switched network.” GOOGLE1001,
`
`8
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`2:57-58. The system includes an instant voice message (IVM) server and IVM
`
`clients. Id., 6:46-7:18, Figure 2. The ’747 patent describes two modes of
`
`operation. In a “record mode,” the user of an IVM client selects one or more IVM
`
`recipients from a list and records an instant voice message, which the IVM client
`
`delivers to the selected recipients via the IVM server and an IP network (e.g., the
`
`Internet). Id., 7:49-8:35. In the “intercom mode,” the IVM client enables real-time
`
`instant voice messaging using one or more buffers to store and transmit successive
`
`portions of an instant voice message until the entire instant voice message has been
`
`transmitted to the IVM server. Id., 11:26-64.
`
`The ’747 patent admits that prior art Voice Over Internet Protocol (VoIP)
`
`and Public Switched Telephone Network (PSTN) systems allowed users to leave
`
`voice messages for later pickup by recipients. GOOGLE1001, 2:18-29. The ’747
`
`patent further admits that sending instant text messages to recipients who are
`
`currently online was in the prior art. Id., 2:30-42. The ’747 patent asserts (albeit
`
`incorrectly) that voice messaging had not previously been combined with instant
`
`messaging. Id., 2:42-49 (“However, notwithstanding the foregoing advances in the
`
`VoIP/PSTN voice communication and voice/text messaging, there is still a need in
`
`the art for providing a system and method for providing instant VoIP messaging
`
`over an IP network.”). The ’747 patent, however, was wrong. As shown in detail
`
`below with respect to claims 1-15, long before the effective filing date of the ’747
`
`9
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`patent, prior art instant voice messaging systems existed that already implemented
`
`or otherwise plainly suggested this solution. GOOGLE1003, ¶¶30; 39-43.
`
`B.
`Summary of the Prosecution
`The application leading to the ’747 patent was filed on March 4, 2009 with a
`
`claim of priority to a prior application filed on December 18, 2003. Claims 1-15
`
`(“the Challenged Claims”) were allowed on February 16, 2012 after a seemingly
`
`cursory examination involving a single office action addressing references not at
`
`issue in this proceeding. GOOGLE1002, 91-95; 111-117; 127. Indeed, the
`
`applicant was able to achieve allowance of the Challenged Claims by simply
`
`submitting a terminal disclaimer and amending certain of the favorably considered
`
`dependent claims to place them in independent form. Id. The examiner provided
`
`the following comments in the Reasons for Allowance:
`
`“The prior art fails to disclose applicant’s method step of instant voice
`messaging whereby the message is generated based on the
`connectivity status of the recipient; neither does the prior art teach
`attaching one or more files to the instant voice message; nor does the
`prior art teach receiving a connectivity status of a list of nodes as
`either being available or unavailable. No obvious combination of
`references found would have taught one of ordinary skill in the art to
`make and use applicant's method as claimed.”
`
`10
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`Id., 127. As described below, other prior art patents and publications taught all
`
`elements of the Challenged Claims, including those elements identified in the
`
`examiner’s Reasons for Allowance.
`
`C. Claim Construction
`For the purposes of IPR only, Petitioner submits that the terms of the ’747
`
`patent are to be given their broadest reasonable interpretation (“BRI”) as
`
`understood by a person of ordinary skill in the art at the time of the alleged
`
`invention (a “POSITA”) in view of the ’747 patent’s specification. 37 C.F.R.
`
`§42.100(b); GOOGLE1003, ¶¶24-25 (level of ordinary skill). For purposes of this
`
`IPR only, Petitioner submits that all claim terms should be given their plain
`
`meaning under the BRI standard, except that Petitioner provides the following
`
`specific construction where the BRI may not be entirely clear:
`
`“list of nodes” and “node” (claim 2) — The terms “list of nodes” and
`
`“node” do not appear in the specification of the ’747 patent, nor were these terms
`
`substantively discussed during prosecution of the ’747 patent. To the extent the
`
`surrounding claim language informs, it suggests that a “node” is simply a
`
`“recipient.” GOOGLE1003, ¶36. For example, claim 2 states: “wherein a node
`
`within the list is adapted to be selected as a recipient of an instant voice message.”
`
`This is consistent with the position Patent Owner has taken in certain district court
`
`proceedings, asserting that the term “node” means “potential recipient.”

`
`Patent Owner’s construction be adopted here because the broadest reasonable
`
`interpretation “must construe the claim language in a way that at least encompasses
`
`the broadest interpretation of the claim language for purposes of infringement.” Ex

`
`V. THERE IS A REASONABLE LIKELIHOOD THAT AT LEAST
`ONE CLAIM OF THE ‘747 PATENT IS UNPATENTABLE
`A.
`[GROUND 1] – Claims 1-6, 8, 12-13 are anticipated by
`Zydney under 35 U.S.C. § 102(b)
`Zydney “relates to the field of packet communications, and more particularly
`
`to voice packet communication systems.” GOOGLE1004, 1:4-5. Zydney sought
`
`to improve upon well-known text-based communication systems such as email and
`
`instant text messaging. Id., 1:6-17. According to Zydney, these text-based
`
`communication systems allowed for the attachment of audio files, but “lack[ed] a
`
`method for convenient recording, storing, exchanging, responding and listening to
`
`voices between one or more parties, independent of whether or not they are
`
`logged in to their network.” Id. Zydney sought to overcome this problem by
`
`disclosing “a system and method for voice exchange and voice distribution
`
`utilizing a voice container . . . [that] can be stored, transcoded and routed to the
`
`appropriate recipients instantaneously or stored for later delivery.” Id., 1:19-22.
`
`12
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`More specifically, Zydney’s technique “provides the ability to store messages both
`
`locally and centrally at the server whenever the recipient is not available for a
`
`prescribed period of time.” Id., 2:3-5.
`
`Zydney’s system architecture is illustrated by the functional block diagram
`
`of Figures 1 and 1A. See generally GOOGLE1004, 10:19-11:23. As shown
`
`below, the basic paradigm of Zydney’s technique involves a sender software agent
`
`(22, yellow) interfacing with a central server (24, pink) to send a voice container
`
`(26) to a recipient software agent (28, blue):
`
`Id., FIG. 1A (color coded). Communications between the software agents (22, 28)
`
`and the central server (24) are conducted over packet-switched networks, such as
`
`
`
`13
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`the Internet (purple), intranets, and/or extranets, via TCP/IP (Transaction Control
`
`Protocol/Internet Protocol) with traditional PSTN network (orange) support. Id.,
`
`5:15-18.
`
`Within the context of Zydney’s architecture, the sender software agent (22)
`
`is configured to execute “a number of distinct modes of communication[.]”
`
`GOOGLE1004, 14:19-20. Zydney describes two particular modes in detail, a
`
`“pack and send mode of operation” (also referred to in Zydney as a “voice mail
`
`conversation” and a “voice instant messaging session”) where “the [entire]
`
`message is first acquired, compressed and then stored in a voice container (26)”
`
`(id., 10:19-11:23, 15:8-16:4) and a “real-time ‘intercom’ [mode] which simulates a
`
`telephone call[.]” (id., 15:8-14, 16:4-15). GOOGLE1003, ¶¶43; 79-81. In one
`
`aspect of Zydney’s disclosure, the choice of communication modes can be “based
`
`on the status of the recipient.” GOOGLE1004, 14:19-20. When an intended
`
`recipient (28) is online, the sender software agent (22) can operate in either the
`
`intercom mode or the pack and send mode of operation. Id., 15:8-14 (“If online,
`
`the originator can either begin a real-time ‘intercom’ call which simulates a
`
`telephone call or a voice instant messaging session, which allows for an
`
`interruptible conversation.”). When an intended recipient (28) is offline, the pack
`
`and send mode is executed. GOOGLE1004, 10:19-11:13, 15:15-21. In either
`
`mode, transmission of the instant voice message may be conducted directly
`
`14
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`between software agents (22, 28) (so-called “peer-to-peer communications”) or
`
`through the central server (24). GOOGLE1003, ¶43 (citing GOOGLE1004, 1:19-
`
`22, 10:19-11:22, 12:1-23, 16:1-21, 24:15-25:9, 27:12-16, 30:1-18, Figures 1, 1A,
`
`8, 11, 14-15, 17). One featured characteristic of Zydney’s pack and send mode is
`
`“the ability to store messages both locally and centrally at the server whenever the
`
`recipient is not available for a prescribed period of time.” Id., 11:1-6.
`
`Claim 1:
`
`
`[1.0]: “A method for instant voice messaging over a packet-switched
`network”
`Even if the preamble were treated as a limitation (which it is not under the
`
`BRI standard), Zydney discloses Element [1.0]. GOOGLE1003, ¶45. Like the
`
`’747 patent, Zydney’s disclosure broadly relates to “the field of packet
`
`communications, and more particularly to voice packet communication systems.”
`
`GOOGLE1004, 1:2-3. Within this field, Zydney teaches “a system and method for
`
`voice exchange and voice distribution utilizing a voice container.” Id., 1:19-20;
`
`see also 1:20-2:10. Zydney further explains that this system and method provides
`
`“the ability to communicate spontaneously, in the user’s own voice, without the
`
`limitations of written communications for natural expression.” Id., 10:11-14. This
`
`results in a “voice intercom system with instant messaging, distributed over the
`
`Internet.” Id., 10:14-18; see also 1:20-22 (“[V]oice containers can be stored,
`
`transcoded and routed to the appropriate recipients instantaneously[.]”). In 2003,
`
`15
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`a POSITA would have known that the Internet is a packet-switched network.
`
`GOOGLE1003, ¶45 (citing GOOGLE1014, 1 (“The Internet is the prime example
`
`of a packet-switched network[.]”); GOOGLE1005, 336). The ’747 patent itself
`
`admits that the Internet is a packet-switched network. GOOGLE1001, 1:33-34
`
`(“In the IP telephony, a VoIP terminal device is connected to a packet-switched
`
`network (e.g., Internet).”).
`
`[1.1]: “generating an instant voice message, wherein generating
`includes recording the instant voice message in an audio file and
`attaching one or more files to the audio file”
`Zydney discloses Element [1.1]. GOOGLE1003, ¶¶46-50. Zydney’s system
`
`allows instant voice message originators (i.e., users) to “digitally record[]
`
`messages for one or more recipients using a microphone-equipped device and the
`
`software agent.” GOOGLE1004, 16:1-4; GOOGLE1003, ¶46. The recorded
`
`messages are placed into transmittable “voice containers,” which Zydney teaches
`
`are “a container object that contains no methods, but contains voice data or voice
`
`data and voice data properties.” GOOGLE1004, 12:6-8; see also generally id., 11-
`
`14. A POSITA would have recognized that a “container object” containing “voice
`
`data” is a “voice message.” GOOGLE1003, ¶47. Moreover, as discussed (supra,
`
`Element [1.0]), Zydney is directed to distributing voice containers
`
`“instantaneously.” GOOGLE1004, 1:20-22, 10:14-18. Thus, Zydney’s “voice
`
`containers” are the claimed “instant voice messages.” GOOGLE1003, ¶47.
`
`16
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`As for the “voice data” contained within the message, a digital recording of
`
`a user’s voice is an “audio file.” GOOGLE1003, ¶48. Indeed, Zydney teaches that
`
`such data can be encoded in an MP3 (MPEP Layer-3) format. GOOGLE1004,
`
`11:14-12:23, 21:14-22:2, cl.19. MP3 is an audio file format. GOOGLE1003, ¶48
`
`(citing GOOGLE1005, 49; 230-231 (explaining that MP3 files are a popular file
`
`format for distributing music audio files)). Thus, Zydney teaches the feature of
`
`“recording the instant voice message in an audio file,” as recited in Element [1.1].
`
`Zydney also teaches attaching files to its voice containers1. GOOGLE1003,
`
`¶¶49-50. As one example, Zydney teaches appending “multimedia attachments” to
`
`
`1 The ’747 patent does not explain exactly how one or more files are attached to an
`
`audio file of the instant message. Rather, the ’747 patent merely states in
`
`conclusory fashion that various files can be “attached to the instant message.” See,
`
`e.g., GOOGLE1001, 12:20-28. Thus, under the BRI, the “attaching” aspect of the
`
`step set forth in Element [1.1] must at least encompass an operation that provides
`
`the end result described by the ’747 patent of an instant voice message, which
`
`comprises an audio file, and at least one other file attached to the instant voice
`
`message. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed. Cir.
`
`1996) (a construction that excludes the preferred embodiment “is rarely, if ever,
`
`correct”).
`
`17
`
`
`
`Attorney Docket No. 19473-0373IP1
`IPR of U.S. Patent No. 8,199,747
`its voice containers, explaining that “[a]nother important application of the present
`
`invention system and method for voice exchange and voice distribution is
`
`attaching other media to the voice containers to provide a richer communications
`
`environment.” GOOGLE1004, 19:2-4; see also Figures 6, 16-18. Zydney
`
`describes attaching “digitized greeting cards” to voice containers as one example
`
`of such a multimedia attachment. Id., 19:4-5; see also 19:6-12 (explaining that
`
`“other data types” can be attached to voice containers), Figures 16-18 (e.g., Step
`
`5.2.1).
`
`In sum, Zydney teaches that its voice container can comprise an audio file
`
`and some other file, e.g., a greeting card, attached to the voice container.
`
`GOOGLE1003, ¶¶46-50. Thus, Zydney discloses the feature of “attaching one or
`
`more files to the audio file” as recited in Element [1.1]. See, supra, n.2 (under
`
`BRI, “attaching one or more files to an audio file” encompasses attaching at least
`
`one other file to an instant voice message). Moreover, should Patent Owner
`
`(improperly) argue that “attaching one or more files” is limited to the ’747 patent’s
`
`preferred embodiment of “attaching one or more documents” (GOOGLE1001,
`
`12:20-24, 13:23-28), Zydney’s disclosure of attachments in the form of “digitized
`
`greeting cards” meets this interpretation under BRI since a greeting card is an
`
`example of a document. GOOGLE1003, ¶50.

`[1.2]: “transmitting the instant voice message having one or more
`recipients”
`Zydney discloses Element [1.2]. GOOGLE1003, ¶¶51-55. Zydney’s
`
`“software agent” (i.e., the “client”) has functionality to “address the recipient(s)”
`
`of an instant voice message. GOOGLE1004, 13:1-6. More specifically, Zydney
`
`teaches how an “originator”—i.e., a user—“selects one or more intended recipients
`
`from a list of names[.]” Id., 14:17-19. Zydney’s software agent is further operable
`
`to transmit the voice container (i.e., the “instant voice message”) to the selected
`
`recipients either directly to the recipients or to an intermediate central server.
`
`GOOGLE1004, 10:19-11:1 (explaining that the software agent can “send, receive
`
`and store messages using voice containers[.]”); see also 1:19-22, 10:19-11:22,
`
`12:1-23, 16:1-21, 24:15-25:9, 27:12-16, 30:1-18, Figures 1, 1A, 8, 11, 14-15, 17.
`
`Thus, when one of Zydney’s software agents transmits a voice container,
`
`such voice container “ha[s] one or more recipients,” as recited in Element [1.2].
`
`GOOGLE1003, ¶¶51-52. Moreover, should Patent Owner (improperly) argue the
`
`above-recited claim language requires that the instant voice message itself contain
`
`the address(es) of the recipient(s), Zydney provides this teaching with respect to its
`
`voice containers. GOOGLE1004, Figure 7 (“. . . THE DESTINATION ADDRESS
`
`OR ADDRESS IN THE FILE STRUCTURE OF THE CONTAINER”); see also
`
`23:1-12 (“Voice container components include . . . one or more recipient’s code
`
`304 [sic]”), Figure 3; GOOGLE1003, ¶¶54-55.
