`
`Declaration of Dr. Vivek Subramanian
`Regarding Petition for IPR of U.S. Patent No. 8,217,902
`
`
`I, Vivek Subramanian, declare as follows:
`
`Introduction
`
`
`
`
`I.
`
`1.
`
`I have been retained by Wintek Corporation (“Petitioner”) as an
`
`independent expert consultant in this proceeding before the United States Patent
`
`and Trademark Office. Although I am being compensated at my rate of $550 per
`
`hour for the time I spend on this matter, no part of my compensation is dependent
`
`on the outcome of this proceeding, and I have no other interest in this proceeding.
`
`2.
`
`I understand that this proceeding involves U.S. Patent No. 8,217,902
`
`(“the ’902 patent”) (Ex. 1001)1, the application for which was filed on August 21,
`
`2007, as U.S. Patent Application No. 11/842,747, and issued on July 10, 2012. I
`
`also understand that the ’902 patent is based on Taiwanese Patent Application No.
`
`96115152, which was filed on April 27, 2007. I further understand that the ’902
`
`patent is assigned on its face to TPK Touch Solutions Inc. (“Patent Owner”).
`
`3.
`
`I have been asked to consider whether certain references disclose or
`
`suggest the features recited in the claims of the ’902 patent. My opinions are set
`
`forth below.
`
`
`1 Where appropriate, I refer to exhibits attached to the petition for Inter Partes
`
`Review of the ’902 patent.

`
`
`
`II. Qualifications
`
`4. My curriculum vitae, which includes a detailed summary of my
`
`background and experience and a list of my publications and patents is attached as
`
`Exhibit 1013.
`
`5.
`
`I am a Professor in the Department of Electrical Engineering &
`
`Computer Sciences at the University of California, Berkeley, located at Berkeley,
`
`California.
`
`6.
`
`I was awarded a B.S. degree from Louisiana State University in 1994,
`
`a M.S. degree from Stanford University in 1996, and a Ph.D. degree from Stanford
`
`University in 1998, all in electrical engineering.
`
`7.
`
`Since 2000, I have held various research and teaching positions in the
`
`Department of Electrical Engineering and Computer Sciences at the University of
`
`California, Berkeley. I have published more than 200 technical papers in journals
`
`and conferences and am an inventor of more than 30 patents covering various
`
`technologies, including semiconductor devices, materials, circuit design, process
`
`technology, and memory architecture.
`
`8.
`
`I also have significant experience in the industry. For example, in
`
`1998, I co-founded Matrix Semiconductor, Inc., a Silicon Valley startup that made
`
`high-density memory devices. I served as Chief Technology Advisor at QuSwami,
`
`
`
`2
`
`Page 10 of 234
`
`

`
`Declaration of Dr. Vivek Subramanian
`Regarding Petition for IPR of U.S. Patent No. 8,217,902
`
`
`
`Inc., from 2008-2011, which is an energy conversion device startup company. I
`
`also founded in 2004 and serve as Scientific Advisor to Kovio, Inc., which is a
`
`printed electronics startup company.
`
`9.
`
`Through the course of my research and development activities in
`
`industry and academia, I have had extensive experience with touch-screen
`
`technology and more generally with display technology as a whole. Starting in
`
`1994, I developed flat panel process technologies for both touch screens and
`
`displays, including specifically developing Indium Tin Oxide (ITO)-based
`
`conductor technology as are discussed in the patent at issue herein. Furthermore, I
`
`have worked on resistive and capacitive touch sensors as part of my academic
`
`research, both as a graduate student, and as a professor, and have also continued to
`
`maintain significant research activities in flat panel displays and user interface
`
`technologies throughout this period.
`
`10.
`
`I am a member of the Institute of Electrical and Electronic Engineers
`
`(IEEE) and have served on the technical committees for the Device Research
`
`Conference and the International Electron Device Meeting. I have also served as
`
`the scientific chair for the Large Area, Organic, and Printed Electronics
`
`Conference (LOPE-C), a major international conference catering to large area
`
`electronic systems such as displays, user interfaces, etc.

`

`
`Declaration of Dr. Vivek Subramanian
`Regarding Petition for IPR of U.S. Patent No. 8,217,902
`
`
`11.
`
`I have received accolades for my achievements in academia as well as
`
`
`
`in the industry. For example, I was awarded the 2005 EDN Innovation Award, I
`
`was awarded the National Science Foundation Young Investigator Award
`
`(CAREER), I was a finalist for 2003 World Technology Award for Information
`
`Technology Hardware, I was nominated to Scientific American’s SA50 List for
`
`Visionary Technology, I was nominated to Technology Review’s list of top 100
`
`young innovators (TR100), and I was nominated to the National Academy of
`
`Engineering’s “Frontiers of Engineering.”
`
`12.
`
`I have previously served as a technical expert in litigations between
`
`Apple and Nokia and between Apple and Motorola in which the patents at issue
`
`related to touch screen technology.
`
`13.
`
`I am not an attorney and offer no legal opinions, but in the course of
`
`my work, I have had experience studying and analyzing patents and patent claims
`
`from the perspective of a person skilled in the art.
`
`III. Summary of Opinions
`
`14. All of the opinions contained in this Declaration are based on the
`
`documents I reviewed and my knowledge and professional judgment. In forming
`
`the opinions expressed in this Declaration, I reviewed the ’902 patent (Ex. 1001);
`
`the prosecution file history for the ’902 patent (Ex. 1002); a Request for Ex Parte
`

`
`

`
`Declaration of Dr. Vivek Subramanian
`Regarding Petition for IPR of U.S. Patent No. 8,217,902
`
`
`
`Reexamination of the ’902 patent and an Order Granting Reexamination (Exs.
`
`1003 and 1004); Japanese Published Patent Application No. 60-75927 and the
`
`corresponding English-language translation thereof (“Fujitsu”) (Exs. 1005 and
`
`1006); U.S. Patent No. 6,137,427 (“Binstead”) (Ex. 1007; Japanese Published
`
`Patent Application No. 61-84729 and the corresponding English-language
`
`translation thereof (“Honeywell”) (Exs. 1008 and 1009); U.S. Patent Application
`
`Publication No. 2005/0030048 (“Bolender”) (Ex. 1010); U.S. Patent No. 5,374,787
`
`(“Miller”) (Ex. 1011); and U.S. Patent Application Publication No. 2007/0229469
`
`(“Seguine”) (Ex. 1012), while drawing on my experience and knowledge of touch
`
`screens.
`
`15. My opinions have been also guided by my appreciation of how a
`
`person of ordinary skill in the art would have understood the claims of the ’902
`
`patent at the time of the alleged invention, which I have been asked to initially
`
`assume is April 27, 2007, the filing date of the Taiwanese priority application.
`
`16.
`
`In my opinion, a person of ordinary skill in the art relevant to the
`
`technology of the ’902 patent would have had a bachelor’s degree in electrical
`
`engineering, or an equivalent field, and two to three years of experience working in
`
`the relevant field, which includes display and/or related user interface device
`
`technologies.

`

`
`Declaration of Dr. Vivek Subramanian
`Regarding Petition for IPR of U.S. Patent No. 8,217,902
`
`
`17. Based on my experience and expertise, it is my opinion that certain
`
`
`
`references disclose or suggest all the features recited in the claims of the ’902
`
`patent.
`
`IV. Overview of the ’902 Patent
`
`18. The ’902 patent is directed to a “conductor pattern structure of a
`
`capacitive touch panel,” and a method of constructing such touch panel. Ex. 1001,
`
`Abstract; see also 3:12-19,2 6:17-33. The ’902 patent purports to “[simplify] the
`
`structure and [reduce] the thickness of the structure” of a capacitive touch panel.
`
`Id. at 3:53-54.
`
`19. Fig. 1 of the ’902 patent illustrates a conductor pattern structure.
`
`
`2 Citations to the ’902 patent refer to column number: line number(s).

`
`
`
`
`
`
`20. The structure includes a plurality of first-axis (X axis) conductor
`
`assemblies 13. See e.g., id. at Fig. 1. Each first-axis conductor assembly 13
`
`includes a plurality of first-axis conductor cells 131 and a plurality of first-axis
`
`conduction lines 132 respectively connecting between adjacent ones of the first-
`
`axis conductor cells 131. See id. The structure further includes a plurality of
`
`insulation layers 17, made of transparent insulation material such as silicon oxide,
`
`covering respective first-axis conduction lines 132. See id. at 5:14-17, Fig. 2. The
`
`insulation layers 17 do not cover the first-axis conductor cells 131. See id. at Fig. 8.

`
`
`21. The structure further includes a plurality of second-axis (Y axis)
`
`
`
`conductor assemblies 14. See id. at Figs. 1 and 2. Each second-axis conductor
`
`assembly 14 includes a plurality of second-axis conductor cells 141 and a plurality
`
`of second-axis conduction lines 142 respectively connecting between adjacent ones
`
`of the second-axis conductor cells 141. See id. at 5:17-29. Each of the second-axis
`
`conduction lines 142 “extends over and across a surface of each insulation layer
`
`17.” Id.
`
`22. According to the ’902 patent, “the first-axis conductor assemblies 13
`
`and the second-axis conductor assemblies 14, and the first-axis and second-axis
`
`conduction lines 132, 142 are made of transparent conductive film, such as ITO
`
`conductive film.” Id. at 5:48-52.
`
`23. Further, the ’902 patent describes a method to manufacture a
`
`conductor pattern structure of a capacitive touch panel. See id. at 6:20-67, Figs. 7-
`
`9. Specifically, the ’902 patent discloses:
`
`FIG. 7 illustrates the schematic view of a surface of a
`substrate on which a plurality of first-axis conductor cells
`131, first-axis conduction lines 132, signal transmission
`lines 16a, 16b, and second-axis conductor cells 141 are
`just formed, and FIG. 8 illustrates the schematic view of
`the substrate surface on which an insulation covering
`layer 17 is formed to cover the surface of each first-axis
`

`
`
`conduction line 132, after the step of FIG. 7. Further, FIG.
`9 illustrates a schematic view of the substrate surface on
`which a second-axis conduction line 142 is formed to
`connect between each pair of adjacent second-axis
`conductor cells 141 of the same second-axis conductor
`assembly, after the step of FIG. 8, to thereby complete
`the manufacturing of the conductor pattern structure of
`the touch panel.
`
`Id. at 6:20-33.
`
`24. With respect to sensing a touch on the capacitive touch panel, the ’902
`
`patent discloses that when a user’s finger touches the touch panel, “the first-axis
`
`conductor cell 131 of the first-axis conductor assembly 13 and the second-axis
`
`conductor cell 141 of the second-axis conductor assembly 14 . . . induce a
`
`capacitor effect therebetween and a signal caused thereby is transmitted through
`
`the signal transmission lines 16a, 16b to the control circuit” to calculate the
`
`position of touch. Id. at 5:64-6:5.
`
`25. Though the ’902 patent has 68 separate claims, the majority of the 13
`
`independent claims and 55 dependent claims are largely redundant, offering only
`
`minor variations to the claim limitations. Accordingly, the claims succinctly fit
`
`into three groups: (1) Group 1 - Independent Apparatus Claims 1, 17, 25, and 16
`
`(and their dependent claims); (2) Group 2 - Independent Method Claims 32, 35, 42,

`
`
`
`44, 58, 66, and 68 (and their dependent claims); and (3) Group 3 - Independent
`
`Apparatus Claims 6 and 53 (and their dependent claims). The three groups are
`
`outlined in the charts below. The minor differences between the claim limitations
`
`within each group are also indicated in the charts. Further, the method claims in
`
`Group 2 also nearly mimic the features of the apparatus claims in Group 1.
