`

`I, Zhi Ding, Ph.D., declare that:
`
`I.
`
`Introduction
`
`1. My name is Zhi Ding, and I have been retained by counsel for Petitioner
`
`Apple, Inc. (“Apple” or “Petitioner”) as an expert witness to provide assistance
`
`regarding U.S. Patent 7,110,779 (“the ’779 Patent”). Specifically, I have been asked
`
`to consider the validity of claims 1-34 of the ’779 Patent (the “Challenged Claims”)
`
`in view of prior art, anticipation and obviousness considerations, and understanding
`
`of a person of ordinary skill in the art (“POSITA”) at the time of the invention, i.e.,
`
`as of the effective filing date of the patent application as it relates to the ’779 Patent.
`
`I have personal knowledge of the facts and opinions set forth in this declaration and
`
`believe them to be true. If called upon to do so, I would testify competently thereto.
`
`2.
`
`I am being compensated for my time at my standard consulting rate. I
`
`am also being reimbursed for expenses that I incur during the course of this work.
`
`My compensation is not contingent upon the results of my study, the substance of
`
`my opinions, or the outcome of any proceeding involving the challenged claims. I

`
`II. Background and Qualifications
`
`6.
`
`I presently hold the title of Distinguished Professor in the Department
`
`of Electrical and Computer Engineering at the University of California, Davis. Since
`
`my appointment on July 1, 2020, I have held the position of professor for the past
`
`22 years and have served as a faculty member at several US universities for over 30
`
`years. I am also a private technical consultant on various technologies related to
`
`information systems. I have more than three decades of research experience on a
`
`wide range of topics related to data communications and signal processing.
`
`7.
`
`I earned my Bachelor of Science degree in 1982 in wireless engineering
`
`from the Nanjing Institute of Technology (later renamed as Southeast University) in
`
`Nanjing, China. I earned my Master of Science degree in 1987 in electrical
`
`6
`
`

`

`engineering from the University of Toronto in Toronto, Canada. I earned my Ph.D.
`
`in 1990 in electrical engineering from Cornell University in Ithaca, New York.
`
`8. My responsibilities as a Professor at University of California, Davis,
`
`include classroom instruction on various topics of communication systems and
`
`signal analysis, as well as mentoring undergraduate students and supervising
`
`graduate students in their research and development efforts on various topics related
`
`to digital communications. I have directly supervised such research and development
`
`works ranging from signal detection to wireless networking. As the chief academic
`
`advisor, I have also directly supervised the completion of over 20 Masters theses and
`
`30 Ph.D. dissertations on various topics related to digital communications. I have
`
`served full time as a faculty member at three major research universities in the
`
`United States over the past 30 years, including Auburn University from 1990 to 1998,
`
`University of Iowa from 1999 to 2000, and University of California, Davis, from
`
`2000 to present.
`
`9.
`
`Since 1990, I have been selected as the principal investigator of
`
`multiple highly competitive federal and local research grants, including more than
`
`twenty major research projects supported by the National Science Foundation and
`
`two research projects funded by the U.S. Army Research Office. These competitive
`
`research projects focused on developing more efficient and effective digital
`
`communication transceivers, networks, and signal processing tools. I have also
`
`7
`
`

`

`participated in several large-scale projects supported by the Defense Advanced
`
`Research Projects Agency (DARPA) with teams of researchers. I have applied for,
`
`and received support from, other federal, state, and industry sponsors.
`
`10.
`
`I have published over 210 peer-reviewed research articles in premier
`
`international journals, in addition to over 240 refereed technical articles at top
`
`international conferences on communications and information technologies.
`
`According to Google Scholar, my published works have been cited by over 13,000
`
`times by peers. I also authored two books on communications technologies. My most
`
`recent book, coauthored with B.P. Lathi, is entitled, “Modern Digital and Analog
`
`Communication Systems,” 5th edition, and was published by the Oxford University
`
`Press in 2018. The 4th edition of this book (published in 2009) had been widely
`
`adopted as an introductory textbook to communication systems.
`
`11.
`
`In addition to the over 450 published technical papers that have been
`
`cited over 15,000 times according to Google Scholar, I am also co-inventor of 4
`
`issued U.S. patents on communication technologies.
`
`12.
`
`I am a member of the Institute of Electrical and Electronics Engineers
`
`(IEEE) and was elevated to the grade of Fellow in January 2003 for contributions
`
`made in signal processing for communication. The IEEE is the world’s largest
`
`professional society of engineers, with over 400,000 members in more than 160
`
`countries. The IEEE has led the development of many standards for modern digital
`
`8
`
`

`

`communications and networking, most notably, the IEEE 802 series of network
`
`standards. The IEEE Grade of Fellow is conferred by the Boards of Directors upon
`
`a person with an extraordinary record of accomplishments in any of the IEEE fields
`
`of interest. The total number selected in any one year does not exceed one-tenth of
`
`one percent of the total voting Institute membership.
`
`13.
`
`I have served the IEEE in the following capacities:
`
`(cid:120) Chief Information Officer of the IEEE Communications Society from
`
`Jan. 2018 to present.
`
`(cid:120) Chief Marketing Officer of the IEEE Communications Society from

`
`(cid:120) Member of the IEEE Signal Processing for Communications Technical
`
`Committee from 1998 to 2004.
`
`14.
`
`In 2012, I received the Wireless Communications Technical Committee
`
`Recognition Award from the IEEE Communications Society, an award given to a
`
`person with a high degree of visibility and contribution in the field of “Wireless and
`
`Mobile Communications Theory, Systems, and Networks.” I received the 2020
`
`Education Award from the IEEE Communications Society. According to the Society,
`
`this award “recognizes distinguished and significant contributions to education
`
`within the Society’s technical scope.”
`
`15.
`
`I have also served as a technical consultant for the telecommunication
`
`industry. For example, in 1995 I consulted for Analog Devices, Inc., on the
`
`development of the first generation DOCSIS cable modem systems. I have also
`
`consulted for other companies, including Nortel Networks and NEC US
`
`Laboratories. I worked as a visiting faculty research fellow at NASA Glenn Research
`
`10
`
`

`

`Center in 1992 and at U.S. Air Force Wright Laboratory in 1993. I have served on
`
`multiple review panels of the National Science Foundation to evaluate competitive
`
`research proposals in the field of communication. I have also reviewed a large
`
`number of research proposals at the request of the National Science and Engineering
`
`Research Council (NSERC) of Canada as an expert panelist from 2010 to 2013, and
`
`also at the request of the Research Grant Council (RGC) of Hong Kong as an external
`
`reviewer.
`
`16.
`
`I have served as an expert witness or consulting expert on a number of
`
`matters related to intellectual property, mostly in the arena of telecommunications,
`
`including cellular communications, Wi-Fi technologies, Bluetooth, and optical
`
`communications. For example, since 2007, I have been engaged to work on various
`
`litigations involving cellular, WiFi, Bluetooth, and optical communication networks.
`
`17. Further experience and a complete list of my publications are presented
`
`in my curriculum vitae. I understand that a copy of my curriculum vitae is attached
`
`as APPLE-1004.
`
`18. Based on my above-described near three decades of experience in
`
`communications technologies, and the acceptance of my publications and
`
`professional recognition by societies in my field, I believe that I am qualified to be
`
`an expert in wireless communication systems, communication networks, and signal
`
`processing.
`
`11
`
`

`

`19. Based on my experiences described above, and as indicated in my
`
`Curriculum Vitae, I am qualified to provide the following opinions with respect to
`
`the patents in this case. Additionally, I was at least a person having ordinary skill in
`
`the art as of January 29, 2004 (“Critical Date”).
`
`III. Level of Ordinary Skill in the Art
`
`20.
`
`In rendering the opinions set forth in this declaration, I was asked to
`
`consider the patent claims and the prior art through the eyes of one of ordinary skill
`
`at the time of the alleged invention, which I understand is asserted to be January 29,
`
`2004 (the filing date of ’779 Patent). I understand that the factors considered in
`
`determining the ordinary level of skill in a field of art include the level of education
`
`and experience of persons working in the field; the types of problems encountered
`
`in the field; the teachings of the prior art, and the sophistication of the technology at
`
`the time of the alleged invention. I understand that one of ordinary skill is not a
`
`specific real individual, but rather is a hypothetical individual having the qualities
`
`reflected by the factors above. I understand that one of ordinary skill would also
`
`have knowledge from the teachings of the prior art, including the art cited below.
`
`21. Taking these factors into consideration, on or before January 29, 2004,
`
`one of ordinary skill relating to the technology of the ’779 Patent would have had a
`
`Bachelor’s degree in electrical engineering, computer engineering, computer science,
`
`or a related field, and 2-3 years of experience in design or development of wireless
`
`12
`
`

`

`communication systems/networks including ranging/positioning systems, or the
`
`equivalent. Additional graduate education could substitute for professional
`
`experience, or significant experience in the field could substitute for formal
`
`education.
`
`22. Before January 29, 2004, my level of skill in the art was at least that of
`
`one of ordinary skill. I am qualified to provide opinions concerning what one of
`
`ordinary skill would have known and understood at that time, and my analysis and
`
`conclusions herein are from the perspective of one of ordinary skill as of that date.
`
`IV. Summary of Opinions and Materials Considered/Relied Upon
`
`23.
`
`In reaching the conclusions described in this declaration, I have relied
`
`on the documents and materials cited herein as well as those identified in this
`
`declaration, including the ’779 Patent, the prosecution history of the ’779 Patent, and
`
`prior art references cited herein. These materials comprise patents, related
`
`documents, and printed publications. Each of these materials is a type of document
`
`that experts in my field would have reasonably relied upon when forming their
`
`opinions.
`
`24.
`
`I have also relied on my education, training, research, knowledge, and
`
`personal and professional experience in the relevant technologies and systems that
`
`were already in use prior to, and within the timeframe of the earliest proclaimed
`
`priority date of the claimed subject matter in the ’779 Patent, which is January 29,
`
`13
`
`

`

`2004 (“Critical Date”).

`
`In my opinion, the Challenged Claims of the ’779 Patent are
`
`unpatentable because they are rendered obvious by the combinations of prior art
`
`references cited in this report and explained herein. The following table summarizes
`
`my opinions.

`
`I am not a lawyer and do not provide any legal opinions, but I have
`
`been advised that certain legal standards are to be applied by technical experts in
`
`forming opinions regarding meaning and validity of patent claims. I have applied
`
`the legal standards described below, which were provided to me by counsel for the
`
`Petitioner.
`
`27.
`
`It is my understanding that assessing the validity of a U.S. patent based
`
`on a prior art analysis requires two steps. First, one must construe the terms of the
`
`patent claims to understand what meaning one of ordinary skill in the art would have
`
`16
`
`

`

`given the terms. Second, after the claim terms have been construed, one may then
`
`assess validity by comparing a patent claim to the “prior art.” I understand that the
`
`teaching of the prior art is viewed through the eyes of one of ordinary skill at the
`
`time of the invention, i.e., as of the effective filing date of the patent application. My
`
`analysis as to what constitutes a relevant POSITA is set forth above.
`
`A. Legal Standards for Claim Construction
`
`28.
`
`I understand that, for purposes of my analysis in this IPR, the terms
`
`appearing in the patent claims should be interpreted according to their “ordinary and
`
`customary meaning.” In determining the ordinary and custom meaning, I understand
`
`that the words of a claim are first given the plain meaning that those words would
`
`have had to a person of ordinary skill in the art (“POSITA”) at the time of the
`
`invention, i.e., as of the effective filing date of the patent application. I also
`
`understand that the structure of the claims, the specification, and file history also
`
`may be used to better construe a claim insofar as the plain meaning of the claims
`
`cannot be understood. Moreover, I understand that even treatises and dictionaries
`
`may be used, albeit under limited circumstances, to determine the meaning attributed
`
`by a POSITA to a claim term at the time of the invention.
`
`29.
`
`I also understand that the words of the claims should be interpreted as
`
`they would have been interpreted by a POSITA at the time of the invention (not
`
`today).
`
`17
`
`

`

`30.
`
`I have followed these guidelines in my analysis, and, unless otherwise
`
`indicated, I have applied the plain and ordinary meaning of the claim terms.
`
`B.
`
`Legal Standard for Obviousness
`
`31. My understanding is that a patent claim is invalid as obvious only if the
`
`subject matter of the claimed invention “as a whole” would have been obvious to
`
`one of ordinary skill at the time of the invention, i.e., as of the effective filing date
`
`of the patent application. To determine the differences between a prior art reference
`
`(or a proposed combination of prior art references) and the claims, the question of
`
`obviousness is not whether the differences themselves would have been obvious, but
`
`whether the claimed invention as a whole would have been obvious. Also,
`
`obviousness grounds cannot be sustained by mere conclusory statements. Rather, it
`
`is necessary to provide some articulated reasoning with rational underpinning to
`
`support the legal conclusion of obviousness.
`
`32.
`
`I understand that a patent claim that comprises several elements is not
`
`proved obvious by simply showing that each of its elements was independently
`
`known in the prior art. In my evaluation of whether any claim of the ’779 Patent
`
`would have been obvious, I considered whether the Petition, or any evidence
`
`submitted in this proceeding, presented an articulated reason with a rational basis
`
`that would have motivated one of ordinary skill to combine the elements or concepts
`
`from the prior art in the same way as in the claimed invention.
`
`18
`
`

`

`33.
`
`It is my understanding that there is no single way to define the line
`
`between true inventiveness on one hand—which is patentable—and the application
`
`of common sense and ordinary skill to solve a problem on the other hand—which is
`
`not patentable. For instance, factors such as market forces or other design incentives
`
`may be the source of what produced a change, rather than true inventiveness.
`
`34.
`
`I understand that the decision-maker may consider whether the change
`
`was merely the predictable result of using prior art elements according to their
`
`known functions, or whether it was the result of true inventiveness. And, the
`
`decision-maker may also consider whether there is some teaching or suggestion in
`
`the prior art to make the modification or combination of elements recited in the claim
`
`at issue. Also, the decision-maker may consider whether the innovation applies a
`
`known technique that had been used to improve a similar device or method in a
`
`similar way. The decision-maker may also consider whether the claimed invention
`
`would have been obvious to try, meaning that the claimed innovation was one of a
`
`relatively small number of possible approaches to the problem with a reasonable
`
`expectation of success by those skilled in the art.
`
`35.
`
`I have been instructed by counsel that if any of these considerations are
`
`relied upon to reach a conclusion of obviousness, the law requires that the analysis
`
`of such a consideration must be made explicit. I understand that the decision-maker
`
`must be careful not to determine obviousness using the benefit of hindsight and that
`
`19
`
`

`

`many true inventions might seem obvious after the fact. I understand that the
`
`decision-maker should consider obviousness from the position of one of ordinary
`
`skill at the time of the invention and that the decision-maker should not consider
`
`what is known today or what is learned from the teaching of the patent.
`
`36.
`
`I understand that in order to determine whether a patent claim is
`
`obvious, one must make certain factual findings regarding the claimed invention and
`
`the prior art. Specifically, I understand that the following factors must be evaluated
`
`to determine whether a claim is obvious: the scope and content of the prior art
