`
`I.
`
`INTRODUCTION
`
`Declaration of Dr. Samuel H. Russ
`U.S. Pat. No. 7,589,642
`
`
`1.
`
`
`I have been asked by Roku, Inc. (“Roku”) to provide expert opinions
`
`in the above-captioned Inter Partes Review proceeding involving U.S. Patent No.
`
`7,589,642 (“the ’642 patent”), which is entitled “Relaying Key Code Signals
`
`Through A Remote Control Device.”
`
`2.
`
`
`I am being compensated by Roku on an hourly basis for the time I
`
`spend in connection with this proceeding. My compensation is not dependent in
`
`any way on the substance of my opinions or in the outcome of this proceeding.
`
`II. QUALIFICATIONS
` My qualifications for forming the opinions set forth in this declaration 3.
`
`
`are summarized here and explained in more detail in my curriculum vitae, which is
`
`attached as Exhibit 1004. Exhibit 1004 also includes a list of my publications and
`
`the cases in which I have testified at deposition, hearing, or trial during the past
`
`four years.
`
`4.
`
`
`I received a Bachelor’s degree in Electrical Engineering from the
`
`Georgia Institute of Technology (“Georgia Tech”) in 1986 and a Ph.D. in
`
`Electrical Engineering from Georgia Tech in 1991.
`
`5.
`
`
`From 2007 to the present, I have been a member of the faculty of the
`
`University of South Alabama as an Assistant and Associate Professor in the
`
`
`
`- 1 -
`
`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`Department of Electrical and Computer Engineering. During that time, I have won
`
`awards for excellent teaching and have been actively publishing research in home
`
`networking and digital video recording (DVR) technologies. I am active in the
`
`Institute of Electrical and Electronic Engineers (IEEE) and am a Distinguished
`
`Lecturer for the IEEE Consumer Electronics Society. As a consultant, I have
`
`conducted briefings for members of the financial community on technology trends
`
`in the cable, satellite, and IPTV sectors.
`
`6.
`
`
`From 2000 to 2007, I worked for Scientific-Atlanta (now Cisco’s
`
`Service Provider Video Tech. Group), where I managed a cable set-top box (STB)
`
`design group that designed four STB models, including the Explorer 4200
`
`(nonDVR) and 8300 (DVR) models. Both models sold several million units. As
`
`design-group manager, I was responsible for managing the design and prototyping
`
`activities of the group and for interfacing with other groups (especially integrated-
`
`circuit design, procurement, software developers, the factory where prototypes
`
`were built, and product managers) and for maintaining the hardware and
`
`mechanical development schedule. Since the products were produced in extremely
`
`high volumes, the projects had very high visibility in the company, and therefore
`
`carried a great deal of responsibility.
`
`7.
`
`
`Also while at Scientific-Atlanta, I became a staff expert in home
`
`networking, conducting demonstrations of wireless video
`
`technology and
`
`
`
`- 2 -
`
`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`managing a group that developed a new coaxial home networking system. The
`
`coaxial system won a Technology and Engineering Emmy® Award in 2013. I
`
`became a staff expert in DVR reliability, and led a team that improved the
`
`software, hardware, repair, and manufacturing processes. I am a named inventor on
`
`fifty-one (51) patent applications that were filed while I was at Scientific-Atlanta,
`
`twenty eight (28) of which have issued as U.S. patents as of the writing of this
`
`report.
`
`8.
`
`
`From 1999 to 2000, I was a Staff Electrical Engineer and then Matrix
`
`Manager at IVI Checkmate (now Ingenico), where I managed the hardware design
`
`team that completed the design of the eN-Touch 1000 payment terminal. This
`
`terminal was in widespread use, for example, at the self-checkout at Home Depot.
`
`9.
`
`
`I also served on the faculty of Mississippi State University from 1994
`
`to 1999 as an Assistant Professor in the Department of Electrical & Computer
`
`Engineering where I taught circuit board design and two-way interactive video
`
`classes, among other things.
`
`10.
`
`
`I have also authored 32 journal articles and conference papers. A
`
`recent conference paper on digital video recording won second place in a “best
`
`paper” competition at the 2011 International Conference on Consumer Electronics
`
`in Las Vegas, NV.

`
`IV. RELEVANT LEGAL STANDARDS
`12.
`I have also relied upon various legal principles (as explained to me by
`
`
`Roku’s counsel) in formulating my opinions. My understanding of these principles
`
`are summarized below.
`
`13.
`
`
`I understand that a patent claim defines the metes and bounds of an
`
`alleged invention. I further understand that a claimed invention must be new,
`
`useful, and non-obvious over the prior art for it to be patentable. I understand that
`
`in this proceeding Roku has the burden of proving that the challenged claims are
`
`unpatentable over the prior art by a preponderance of the evidence. I understand
`
`
`
`- 5 -
`
`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`that “a preponderance of the evidence” is evidence sufficient to show that a fact is
`
`more likely true than it is not.
`
`14.
`
`
`In determining the patentability of a claim, I understand that the first
`
`step is to construe the claim from the perspective of a person of ordinary skill in
`
`the art (“POSA”) to determine its meaning and scope. Once construed, I
`
`understand that the claim is to be considered against the prior art from the
`
`perspective of a POSA as further summarized below.
`
`A. Level of ordinary skill
`15.
`I understand that a claim must be analyzed from the perspective of a
`
`
`POSA at the time the claimed invention was allegedly invented by the patentee.
`
`Roku’s counsel has asked me to consider the time period shortly before December
`
`16, 2003, which is the earliest priority date of the ’642 patent, as the potential date
`
`of invention of the claims of the ’642 patent.
`
`16.
`
`
`In ascertaining the appropriate level of ordinary skill in the art of a
`
`patent, I understand that several factors should be considered including (1) the
`
`types of problems encountered in the art; (2) the prior art solutions to those
`
`problems; (3) the rapidity with which innovations are made; (4) the sophistication
`
`of the technology; and (5) the educational level of active workers in the field of the
`
`patent.
`
`
`
`- 6 -
`
`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`17.
`
`
`I further understand that a POSA is a person who is presumed to be
`
`aware of the pertinent art, thinks along conventional wisdom in the art, and is a
`
`person of ordinary creativity. Accordingly, a POSA of the ’642 patent would have
`
`had general knowledge of remote control devices, consumer electronic devices,
`
`and various related technologies as of December 16, 2003.
`
`
`
` Thus based on my experience and my understanding of the legal 18.
`
`principles summarized here, I believe that a POSA in the context of the ’642 patent
`
`at the time of the patent’s earliest priority date of December 16, 2003, would have
`
`had a bachelor’s degree in electrical engineering or equivalent degree with two
`
`years of work experience relating to communications and consumer electronics.
`
`Well before December 16, 2003, my level of skill in the art was at least that of a
`
`POSA, as discussed above.
`
`B. Claim construction
`19.
`I have been informed by Roku’s counsel that in this proceeding, the
`
`
`United States Patent and Trademark Office (“PTO”) interprets the claims of an
`
`unexpired patent, such as the ’642 patent, under the same standards used in a
`
`United States District Court. This includes interpreting the claims through the lens
`
`of POSA in view of the entire patent. Accordingly, in formulating my opinions, I
`
`have reviewed the claims of the ’642 patent as I perceive a POSA would have
`
`understood them at the time of the earliest priority date (December 16, 2003) of the
`
`
`
`- 7 -

`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`’642 patent, after reading the entire ’642 patent specification. I have also reviewed
`
`a Markman order provided by the district court in a pending proceeding also
`
`directed to the ’642 patent.
`
`
`
` Finally, I have been informed that claim construction is ultimately a 20.
`
`question of law. Accordingly, I understand that a tribunal may choose to construe
`
`certain terms to provide clarity to the proceeding should any dispute arise between
`
`the parties over how a term should be construed. If the tribunal chooses to construe
`
`any term, then I reserve my right to review and potentially modify any opinions
`
`below in view of such constructions.
`
`“Key code”
`
`1.
`
`I understand that in the related district court proceeding, Patent Owner
`
`21.
`
`
`and Petitioner have previously agreed to a construction for “key code” as being a
`
`“a code corresponding to the function of an electronic device, optionally including
`
`timing information.” EX1010, Markman order, 12. While a POSA reading the
`
`term “key code” would understand the term as having its plain and ordinary
`
`meaning, the combination of references described below in Grounds 1-3 render
`
`obvious the claims of the ’642 patent under its plain and ordinary meaning or the
`
`agreed-upon construction.
`
`“Keystroke indicator signal”
`
`2.
`
`I understand that in the related district court proceeding, Patent Owner
`
`22.
`
`
`
`
`- 8 -
`
`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`and Petitioner have previously agreed to a construction for “keystroke indicator
`
`signal” and “keystroke indicator” as being a “a signal, distinct from a key code,
`
`corresponding to a pressed key [on a remote control].” EX1010, 12-13. While a
`
`POSA reading the term “keystroke indicator signal” would understand the term as
`
`having its plain and ordinary meaning, the combination of references described
`
`below in Grounds 1-3 render obvious the claims of the ’642 patent under its plain
`
`and ordinary meaning or the agreed-upon construction.
`
`“Key code signal”
`
`3.
`
`I understand that in the related district court proceeding, Patent Owner
`
`23.
`
`
`has previously provided a construction for “key code signal” as being “a signal
`
`containing a key code.” EX1010, 13. I understand that the court considered this
`
`construction and provided its own construction of a “signal containing a modulated
`
`key code.” EX1010, 13-23. While a POSA reading the term “key code signal”
`
`would understand the term as having its plain and ordinary meaning, the
`
`combination of references described below in Grounds 1-3 render obvious the
`
`claims of the ’642 patent under its plain and ordinary meaning or either the Patent
`
`Owner’s or the court’s constructions.
`
`“Key code generator device”
`4.
`
`I understand that from the Markman order set out in the corresponding
`
`24.
`
`
`district court proceeding, Patent Owner previously proposed a construction for
`
`
`
`- 9 -
`
`Universal Electronics Inc., Exhibit 2011
`Roku, Inc. v. Universal Electronics Inc., IPR2019-01614
`
`
`
`“key code generator device” as being “an electronic consumer device, other than a
`
`remote control, that identifies a codeset and generates a key code from the
`
`identified codeset.” EX1010, 23. Patent Owner further stated that “key code
`
`generator device” was not governed by 35 U.S.C. § 112(6), but to the extent 35
`
`U.S.C. § 112(6) applied, the corresponding structure would be a “set-top box,
`
`television, a stereo radio, a digital video disk player, a video cassette recorder, a
`
`personal computer, a set-top cable television box or a set-top satellite box and
`
`equivalents thereof.” EX1010, 23.
`
`
`
` The court construed the claim as being subject to 35 U.S.C. § 112(6) 25.
`
`and construed the corresponding function as “generate a key code” and the
`
`corresponding structure as Patent Owner’s proposed structure. The court also
`
`construed the “key code generator device” as performing the steps of “(1)
`
`identifying a codeset usable to communicate with an electronic consumer device”
`
`and “(2) identifying the key code corresponding to a pressed key for that codeset.”
`
`EX1010, 23-30 (citing ’642 patent, 9:60–66, 3:9–12, 7:4–43, 7:60–8:18, 8:28–
`
`9:14, 4:24–26, 6:24–25). While a POSA reading the term “key code generator
`
`device” would understand the term as having its plain and ordinary meaning, the
`
`combination of references described below in Grounds 1-3 render obvious the
`
`claims of the ’642 patent under its plain and ordinary meaning or either the Patent
`
`Owner’s or the court’s constructions.

`
`
`
`C. Obviousness
`26.
`I have been informed by Roku’s counsel that a patent claim is
`
`
`unpatentable if the differences between the claimed invention and the prior art are
`
`such that the claimed invention as a whole would have been obvious to a POSA at
`
`the time the claimed invention was allegedly invented by the patentee. Thus in
`
`assessing whether a claim is obvious, I understand that I am to consider (1) the
`
`scope and content of the prior art; (2) the level of ordinary skill in the field of the
`
`invention; (3) the differences between the claimed invention and the prior art; and
`
`(4) any objective evidence of non-obviousness.
`
`27.
`
`
`I understand that if a POSA would have arrived at a claimed invention
`
`when it was allegedly invented by the patentee by (a) combining prior art elements
