`“Xia” Declaration of Dr. Harry V. Bims
`U.S. Patent No. 10,568,113
`
`I.
`1.
`
`INTRODUCTION
`I, Harry V. Bims, Ph.D., have been retained as an independent expert by
`
`Samsung Electronics Co., Ltd., and Samsung Electronics America, Inc.
`
`(“Petitioner” or “Samsung”) in connection with an inter partes review (IPR)
`
`of U.S. Patent No. 10,568,113 (“the ’113 patent”) (Ex. 1001). I have
`
`prepared this declaration in connection with Samsung’s Petition for Inter
`
`Partes Review.
`
`2.
`
`Specifically, this document contains my opinions about the technology in
`
`claims 1-20 of the ’113 patent and the grounds against these claims that have
`
`been asserted by Samsung. I was not asked to provide any opinions about
`
`the ’113 patent that are not expressed herein.
`
`II.
`3.
`
`SUMMARY OF OPINIONS
`This declaration considered claims 1-20 of the ’113 patent. Below, I set forth
`
`the opinions I have formed, the conclusions I have reached, and the bases for
`
`these opinions and conclusions. I believe the statements contained in this
`
`declaration to be true and correct to the best of my knowledge.
`
`4.
`
`Based on my experience, knowledge of the art at the time of the applicable
`
`priority date (I was told to assume a priority date of August 11, 2017), it is
`
`my opinion that claims 1-20 of the ’113 patent would have been obvious
`
`based on the asserted grounds.

`I am being compensated for my time at the rate of $700 per hour. This
`
`5.
`
`compensation is in no way contingent upon the nature of my findings, the
`
`presentation of my findings in testimony, or the outcome of this proceeding.
`
`III. QUALIFICATIONS AND BACKGROUND
`6.
`I believe that I am well qualified to serve as a technical expert in this matter
`
`based upon my qualifications, discussed in detail below. A copy of my
`
`curriculum vitae is attached as Appendix A to this declaration.
`
`7.
`
`Based on my education, research, and work experience, I am knowledgeable
`
`about the subject matter of the ’113 patent and the related prior art.
`
`8.
`
`For more than 30 years, since approximately 1981, I have studied, designed,
`
`and worked in the field of telecommunications, including wireless
`
`communications. During this period, I have designed and implemented
`
`various products involving cellular communication technology.
`
`9.
`
`I received a B.S. in Computer and Systems Engineering from Rensselaer
`
`Polytechnic Institute in 1985. I received an M.S. in Electrical Engineering in
`
`1988 and a Ph.D. in Electrical Engineering in 1993, both from Stanford
`
`University. As a graduate student, I studied the principle of Digital
`
`Communications theory, including data modulation and demodulation,
`
`signal constellations and lattices, channel estimation, equalization, filtering,
`
`precoding, synchronization, and trellis coding. My Ph.D. thesis addressed
`
`
`
`2
`
`

`

`“Xia” Declaration of Dr. Harry V. Bims
`U.S. Patent No. 10,568,113
`the application of trellis coding and precoding to a digital modulation
`
`system, and was titled “Trellis Coding for Multi-Level, Partial Response
`
`Continuous Phase Modulation with Precoding.”
`
`10. After receiving my Ph.D. in 1993, I worked for Glenayre Technologies –
`
`Wireless Access Group, where I worked on applications for wireless
`
`communication, including inventing, designing, and building a patented two-
`
`way pager test system and co-developing a wireless application protocol.
`
`11.
`
`In January of 1999, I launched a technology consulting company,
`
`Protocomm Systems Inc., which focuses on the development of advanced
`
`wireless communications protocols and related software implementations for
`
`wireless product companies.
`
`12. From 1999 to 2001, I was also the Director of Software Architecture for
`
`Symmetry Communications System. I this position, I was responsible for the
`
`software architecture for core SGSN (Serving GPRS Support Node) and
`
`GGSN (Gateway GPRS Support Node) products for the GPRS (Generic
`
`Packet Radio Services) market. I also held management responsibility for
`
`the Firmware, Hardware, Performance, and Systems Engineering Groups.
`
`13.
`
`In 2001, I developed a business plan for building network infrastructure for
`
`Institute of Electrical and Electronics Engineers (“IEEE”) 802.11 standard
`
`(“Wi-Fi”) enterprise networks, and then later that year founded AirFlow
`
`
`
`3
`
`

`

`“Xia” Declaration of Dr. Harry V. Bims
`U.S. Patent No. 10,568,113
`Networks, Inc. where I invented and received eleven patents on a distributed
`
`antenna system design for wireless networks, based on the 802.11 wireless
`
`local area network specification.
`
`14.
`
`I am currently the President of Protocomm Systems, LLC and Bims
`
`Laboratories, LLC, both of which I founded. As the President of Bims
`
`Laboratories, I perform technical research in wireless technology standards,
`
`such as UMTS, LTE/4G, 5G, Wi-Fi, Bluetooth, and other network
`
`communication protocols. I am named as an inventor of twenty-three

`
`In addition, I am a named Technical Expert and former Vice-Chair and
`
`Secretary of the IEEE 802.16 Working Group, which develops technical
`
`standards for the wireless protocol commonly known as WiMax. I am also a
`
`voting member of the IEEE 802.11 Working Group (which develops
`
`technical standards for WiFi), and the IEEE 802.15 Working Group (which
