`

`
`I, Dr. Val DiEuliis, hereby declare and state as follows:
`
`1.
`
`1.
`
`Introduction
`
`My name is Val DiEuliis, and I have been retained by
`
`Uniloc, USA, Inc. and Uniloc Luxembourg S.A. (“Uniloc” or the “Patent
`
`Owner”). My client Uniloc and its associated counsel, Etheridge Law
`
`Group, have asked me to study U.S. Patent No. 7,535,890 (“the ’890
`
`patent”), the Petition, the proffered prior art in this case, and other
`
`relevant documents. I document my findings in this declaration.
`
`2.
`
`I have concluded that International Application
`
`WO 01/11824 (“Zydney”) [EX1003], alone or in view of Appelman
`
`[EX1004] and Martin-Flatin [EX1009] does not render obvious any
`
`challenged claim of the patent at issue, the’890 patent, at least for the
`
`following reasons:
`
`• Zydney fails to disclose “transmitting the selected recipients and
`
`the instant voice message therefor over the network” recited in
`
`independent claim 1.
`
`• Zydney fails to disclose “the server receiving the selected
`
`recipients and the instant voice message therefor” recited in
`
`independent claim 1.

`
`Google v. Uniloc, IPR2017-2083
`Uniloc's Exhibit 2001, page 5
`
`

`

`
`
`• Zydney fails to disclose “transmitting the selected recipients and
`
`the instant voice message therefor over the network from the client
`
`to a server” recited in independent claim 40.
`
`• Zydney fails to disclose “receiving the selected recipients and the
`
`instant voice message therefor at the server” recited in independent
`
`claim 40.
`
`3.
`
`In addition, the Petitioners fail to show that the further
`
`limitations of at least dependent claims 5, 6, 42, or 43 are rendered
`
`obvious.
`
`4.
`
`The limited scope of my opinions and analysis in this
`
`declaration do not imply that I may not later express other opinions or
`
`report other results from other investigations concerning other issues
`
`raised by the Petitioners or their experts in this IPR.
`
`2.
`
`5.
`
`Qualifications
`
`I am an electrical engineer with over 45 years of experience
`
`developing, programming, and analyzing computer algorithms and
`
`software. I am experienced with and able to create, read, and interpret
`
`firmware and software in C, C++, Java, assembly language, HTML, and
`
`other computer programming languages. I have served as an expert
`
`witness in multiple cases for which I analyzed computer source code in
`
`
`

`

`

`
`various languages and testified at ITC hearings and two jury trials
`
`concerning my results.
`
`6.
`
`During my career, I have developed and managed projects
`
`for various applications, including sensors, controls, communications,
`
`user interfaces, device firmware, handheld devices, medical devices and
`
`systems, and test systems for optical and magnetic disk systems.
`
`7.
`
`I have designed, developed, and implemented hardware and
`
`software for digital communication networks, including factory
`
`networks; document capture and distribution; and communications links
`
`for various applications. See DiEuliis CV (See e.g., Website
`
`Development, Industrial Valve Position Sensor, Condition-Based
`
`Maintenance System, Avionics Environmental Monitor, Radio Frequency
`
`Billboard Network, Wireless Bar Code System for Hospitals, and ISA
`
`Board for 4-Port RS422 Serial Communications Multiplexer.). See also
`
`Id. at 3 (Digital Document Storage Technology). I also developed an
`
`optical disk digital data storage system that captured, recorded, played
`
`back, and stored digital audio data. Id. at 2 (Optical Disk Technology).

`

`

`
`theory; combinatorics and combinatorial algorithms; and the mathematics
`
`and algorithms of error correcting codes, a field closely related to
`
`cryptography. In addition, as a part of my graduate research, I created and
`
`developed heuristic algorithms and wrote software to synthesize
`
`non-linear codes for optimizing the spectra of coded digital
`
`communications signals.
`
`9.
`
`I received the Ph.D. and M.S. degrees in electrical
`
`engineering from the University of Illinois at Urbana-Champaign in 1978
`
`and 1976, respectively, and the B.S. degree in electrical engineering from
`
`the University of Notre Dame in 1972. I am a Registered Professional
`
`Engineer (electrical) in the State of Minnesota, and a Life Senior Member
`
`of the Institute of Electrical and Electronics Engineers (IEEE).
`
`Additionally, I am a co-inventor of two patents.
`
`10.
`
`I have been an independent engineering consultant, doing
`
`business as Electronics Consultants, since 1984. My clients have
`
`included 3M, Honeywell, Imation Corporation, and Seagate Technology,
`
`among others. Prior to that, I worked as a research engineer for the 3M
`
`Company in St. Paul, Minnesota for five years. In addition, before my

`

`
`with the U.S. Army Security Agency for two years, during which time I
`
`held a Top Secret W/Crypto and SI Access security clearance.
`
`11.
`
`As an adjunct instructor at the University of Saint Thomas in
`
`St. Paul, Minnesota, I developed and presented a lecture on classical
`
`linear control theory for graduate students; developed and taught a
`
`graduate course on computer networks; and taught an undergraduate
`
`analog and digital electronics course to mechanical engineering students.

`
`17.
`
`Legal Standards
`
`I understand there are certain legal rules, standards, or
`
`requirements that I accept for the purpose of my analysis of the opinions
`
`and conclusions set forth in this declaration.
`
`18.
`
`I understand a patent is obvious “if the differences between
`
`the subject matter sought to be patented and the prior art are such that the
`
`subject matter as a whole would have been obvious at the time the
`
`invention was made to a person having ordinary skill in the art to which
`
`said subject matter pertains.” 35 U.S.C. § 103(a). An obviousness
`
`determination must be based on four factual inquiries: (1) the scope and
`
`content of the prior art; (2) the differences between the claims and the
`
`prior art; (3) the level of ordinary skill in the art; and (4) objective indicia
`
`of nonobviousness.
`
`19.
`
`I have been informed that if a single limitation of a claim is
`
`absent from the prior art, the claim cannot be considered obvious.
`
`20.
`
`I further understand that it is improper to combine references
`
`where the references teach away from their combination. A prior art
`
`reference teaches away from the claimed invention when a person of
`
`ordinary skill, upon reading the reference would be led in a direction
`
`divergent from the path that was taken by the applicant. Prior art also
`
`
`IPR2017-01523: Declaration of Dr. Val DiEuliis
`
`
`Page 12 of 65
`
`Google v. Uniloc, IPR2017-2083
`Uniloc's Exhibit 2001, page 12
`
`

`

`
`teaches away when it criticize[s], discredit[s], or otherwise discourage[s]
`
`investigation into the claimed invention. Additionally, a reference teaches
`
`away from a combination when using it in that combination would
`
`produce an inoperative result. A reference also teaches away from a
`
`combination when using it in that combination would render the
`
`invention described in the reference unsatisfactory for its intended
`
`purpose.
`
`21.
`
`In addition, I understand that if a proposed modification or
`
`combination of the prior art would change the principle of operation of
`
`the prior art device being modified, then the teachings of the references
`
`are not sufficient to render the claims prima facie obvious.
`

`

`
`The ’890 Patent
`
`U.S. Patent No. 7,535,890 (“’890”), titled System and
`
`method for instant VoIP messaging, was issued on May 19, 2009. The
`
`application 10/740,030, by inventor Michael J. Rojas, was filed on
`
`December 18, 2003. See EX1001.
`
`23.
`
`The ’890 patent “relates to Internet telephony (IP
`
`telephony). More particularly, the present invention is directed to a
`
`system and method for enabling local and global instant VoIP
`
`
`
`IPR2017-01523: Declaration of Dr. Val DiEuliis
`
`
`Page 13 of 65
`
`Google v. Uniloc, IPR2017-2083
`Uniloc's Exhibit 2001, page 13
`
`

`

`
`messaging over an IP network, such as the Internet, with PSTN
`
`support.” Id. at 1:7-11.
`
`24.
`
`The ’890 patent provides the historical context in its prior art
`
`discussion by noting that “[traditional] telephony is based on a public
`
`switched telephone network (i.e., “PSTN”). EX1001 at 1:13-23. This is
`
`the well-known telephone system that has served the world for well over
`
`a century.
`
`25.
`
`The ’890 patent further explains “An alternative to the
`
`PSTN is Voice over Internet Protocol (i.e., "VoIP"), also known as IP
`
`telephony or Internet telephony. Id. at 1:24-26. The patent elaborates as
`
`follows:
`
`In the IP telephony, a VoIP terminal device is
`connected to a packet-switched network (e.g.,
`Internet) and voice communication from the
`VoIP terminal device is digitized, packetized
`and transmitted over the packet-switched
`network to a destination VoIP terminal device,
`which reconstructs the packets and audibly
`plays, stores or otherwise processes the
`transmission. The VoIP terminal device may be a
`VoIP telephone or a general-purpose personal
`computer (PC) enabled for IP telephony. More
`specifically, the PC is programmed with the
`software and equipped with audio input/output
`devices (e.g., a combination of microphone and
`
`
`
`IPR2017-01523: Declaration of Dr. Val DiEuliis
`
`
`Page 14 of 65
`
`Google v. Uniloc, IPR2017-2083
`Uniloc's Exhibit 2001, page 14
`
`

`

`
`
`speaker or a headset) to serve as a VoIP terminal
`device. The PC so enabled and equipped will
`herein be referred to as a VoIP terminal device or a
`VoIP softphone.
`(Id. at 1:26-39) (Emphasis added.)
`
`
`26.
`
`After noting that VoIP and instant text messaging were
`
`known arts, the ’890 patent explains the motivation for its invention as
`
`follows:
`
`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. More particularly, there is a need in the
`art for providing local and global instant voice
`messaging over VoIP with PSTN support.
`(Id. at 2:36-42) (Emphasis added.)
`
`
`27.
`
`FIG. 2, reproduced below is “an exemplary illustration of a
`
`local instant voice messaging (IVM) system 200 according to the
`
`present invention.” Id. at 2:40-42. The instant voice messaging system
`
`200 comprises a local IVM server 202 that “provides the core
`
`functionality for enabling instant voice messaging with PSTN support
`
`according to the present invention.” Id. at 6:42-45 (emphasis added).

`The local IVM server 202 “is enabled to provide instant
`
`voice messaging to one or more IVM clients 206 and 208, as well support
`
`instant voice messaging for PSTN legacy telephones 110.” Id. at 6:47-51.
`
`The local IP network 204, a packet-switched network, connects the IVM
`
`server 202 to clients 208 (viz., a computer system), VoIP Phone 206, and
`
`legacy telephone 110 (e.g., a land-line phone). Clients incorporate

` A POSITA would have understood, upon studying the
`
`totality of the ’890 patent, and specifically the written descriptions above
`
`and elsewhere in the ’890 patent, that “clients” in the ’890 patent are
`
`devices, such as computers and telephones, and not the people who use
`
`the devices. See e.g., Id. at 9:18-19. The patent expresses this in the
`
`following exemplary passages:
`
`The IVM client 208 is a general-purpose
`programmable computer equipped with a
`network interface (not shown), such as an Ethernet
`card, to provide connectivity to the network 204.
`(Id. at 12:2-5)
`
`The user operates the IVM client 208 by using
`the input device 218 to indicate a selection of one
`or more IVM recipients from the list.
`(Id. at 7:58-61; also 8:46-48 [“the user operates ...
`using a keypad ...”]) (Emphasis added.)
`
`The one or more recipients are enabled to display
`an indication that the instant voice message has
`been received and audibly play the instant voice
`message to an associated user.
`(Id. at 8:19-22) (Emphasis added.)

`Uniloc's Exhibit 2001, page 17
`
`

`

`
`30.
`
`The above exemplary passages demonstrate that the user is
`
`not the client, which is a device, but rather an entity (e.g., person, another
`
`device, software) that interfaces with and operates the client device using
`
`input and output devices.
`
`31.
`
`The first passage above explicitly discloses that the client is
`
`a computer. The second passage explicitly discloses that the “user”
`
`operates the client.
`
`32.
`
`Finally, the third passage explains that “recipients are
`
`enabled to ... “audibly play the instant voice message to an associated
`
`user.” Id. This exemplary statement explains that a “recipient” is not the
`
`“user.” A POSITA would have understood, after studying the totality of
`
`the ’890 patent, that “recipients” are client devices, not people.
`
`33.
`
`Regarding the operation of at least one embodiment, the
`
`’890 patent explains “the IVM client (VoIP telephone) 208 is connected
`
`over the network 204 to the IVM server 202, which as aforementioned
`
`enables instant voice messaging functionality over the network 204.”
`
`Id. at 8:39-42. The operations proceed generally, according to an
`
`exemplary embodiment, as follows:
`
`• The client displays a list, provided and stored by the server, of one
`
`or more IVM recipients. Id. at 8:42-44.
`
`
`
`IPR2017-01523: Declaration of Dr. Val DiEuliis

`
`

`

`
`
`• “The user operates the IVM client 206 by using a keypad on the
`
`VoIP telephone 206 to indicate a selection of one or more IVM
`
`recipients from the list.” Id. at 8:46-48.
`
`• The client transmits the selection of the recipient(s) to the server.
`
`Id. at 8:48-49.
`
`• The client begins recording audio and the user speaks into a
`
`microphone or headset or telephone handset of the client.
`
`Id. at 8:52-54.
`
`• The client records the user’s speech into an audio file, which may
`
`be stored in a storage device (e.g., memory, magnetic disk). Id. at
`
`9:1-4; see also Id. at 8:11-15.
`
`• The client transmits the recorded audio file (i.e., instant voice
`
`message) to the server via the network. Id. at 8:67-9:2; see also
`
`Id. at 8:14-16.
`
`• The server transmits the instant voice message (that is, the audio
`
`file) to the recipient(s) who are currently connected to the network.
`
`Id. at 9:2-11. If a recipient is not currently connected to the
`
`network, the server temporarily saves the instant voice message
`
`and delivers it to the IVM client when the IVM client connects to
`
`the local IVM server. Id.
`
`
`34.
`
`The ’890 patent also teaches “when an instant voice message
`
`is to be transmitted to the one or more IVM recipients, one or more
`
`documents may be attached to the instant voice message to be stored
`
`
`
`IPR2017-01523: Declaration of Dr. Val DiEuliis
`
`
`Page 19 of 65
`
`Google v. Uniloc, IPR2017-2083
`Uniloc's Exhibit 2001, page 19
`
`

`

`
`or displayed by the one or more selected IVM recipients.”
`
`Id. at 12:22-26. Furthermore, regarding attachments, the patent teaches:
`
`The user may also open any file attachments and
`move or save the files to a separate location on the
`client using a drag-and-drop process.
`(Id. at 12:67-13:3) (Emphasis added.)
`
`The attachment of one or more files is enabled
`conventionally via a methodology such as
`"drag-and-drop" and the like, which invokes the
`document handler 306 to make the appropriate
`linkages to the one or more files and flags the
`messaging system 320 that the instant voice
`message also has the attached one or more files.
`(Id. at 13:26-31)
`
`
`35.
`
`In my opinion, a POSITA would have understood that the
`
`inventor refers to files, such as documents, spreadsheets, pictures, and so
`
`forth, as entities separate from the audio file itself, and that the term
`
`attachment should be interpreted as other files or information that are
`
`sent with a message. For example, a text message may contain a picture
`
`attachment, which is a separate file that is distinct from the actual text in
`
`the message.

`
`limitations recited by the challenged claims.
`
`37.
`
`First, claims 1 and 40, independent system claims, recite the
`
`following limitations:
`
`transmitting the selected recipients and the instant
`voice message therefor over the network
`(EX1001 at 23:60-61) (Claim 1)
`
`the server receiving the selected recipients and the

`
`

`

`
`
`(Id. at 24:8-12) (Claim 4)
`
`wherein the method further comprises: requesting
`from the client a list of recipients associated with
`the client from the server; and transmitting from
`the server the list of recipients to the client for
`selection of the one or more recipients
`(Id. at 28:41-46) (Claim 41)
`
`
`39.
`
`Third, claims 5 and 42, dependent on claims 1 and 40,
`
`respectively, recite the further limitations as follows:
`
`wherein the server delivers the instant voice
`message to the selected recipients that are
`available
`(Id. at 24:13-15) (Claim 5)
`
`delivering the instant voice message from the
`server to the selected recipients that are available
`(Id. at 28:47-50) (Claim 42)
`
`
`40.
`
`Fourth, claims 6 and 43, dependent on claims 1 and 40,
`
`respectively, recite the further limitations as follows:
`
`wherein the client records the instant voice
`message in an audio file, transmits the audio file to
`the server, and the server delivers the audio file to
`the selected recipients, the selected recipients
`being enabled to audibly play the audio file
`(Id. at 24:16-20) (Claim 6)

`
`41.
`
`recording the instant voice message at the client in
`an audio file; transmitting the audio file to the
`server; delivering the audio file from the server to
`the selected recipients; and audibly playing the
`audio file at the least one of the selected recipients
`(Id. at 28:51-59) (Claim 43)
`
`
`Ordinary Skill in the Art
`
`The Petitioners’ expert, Dr. Lavian, defines a person of
`
`ordinary skill in the art as a person who “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).” EX1002 at ¶ 15; also
`
`Pet. at 6.
`
`42.
`
`I have no reason to disagree with Dr. Lavian’s description of
`
`a person of ordinary skill in the art. Moreover, based on my degrees in
`
`electrical engineering, which included extensive training in software
`
`development, data communications and networking, and 45-plus years of
`
`experience, including significant software development, I had, on the
`
`priority date, considerably more experience and expertise than the
`
`POSITA. I base my opinions regarding the level of ordinary skill in the
`
`

`

`
`art upon this understanding and my own experience in the field. I have
`
`considered the way in which a POSITA would have understood the ’890
`
`patent on its priority date,
`

`
` and I offer my opinions on that basis.
