`Each of my academic degrees involved significant studies in solid
`
`9.
`
`state physics, semiconductor devices, electrical engineering, electronic systems,
`
`electromagnetics, optics, radio frequency systems, and antennas. For example,
`
`courses relating to these fields that I took include two years of study in
`
`electromagnetics and optics, one year of study in solid state and semiconductor
`
`physics, as well as four years of graduate research in electronic devices, antenna
`
`design, antenna fabrication, microwave systems, including mixing and both
`
`frequency down-conversion and up-conversion, and optical systems.
`
`10. My Ph.D. thesis was on the design and fabrication of high frequency
`
`electromagnetic detectors and quasi-optical imaging antenna arrays, including
`
`research on integrated-circuit fabrication, high frequency RF semiconductor
`
`devices, integrated circuits, antennas, sensors, and IC packaging.
`
`11.
`
`I designed and fabricated the first monolithic integrated-circuit
`
`imaging antenna array for use at wavelengths in the far infrared (sometimes
`
`referred to as the terahertz) region of the electromagnetic spectrum. For this work
`
`on the first high resolution focal plane antenna array for use at wavelengths
`
`between 0.1 mm and 1 mm I was awarded the 1984 Marconi International
`
`Fellowship Young Scientist Award “for contributions to the development of
`
`millimeter wave integrated circuits especially in the area of detectors and imaging
`
`arrays.”

`12. My work as a professor began in 1984, when I joined the University
`
`of Texas at Austin as an assistant professor. In 1988 I became an associate
`
`professor, and in 1992 became a full professor.
`
`13.
`
`I received the 1986 National Science Foundation Presidential Young
`
`Investigator for research in terahertz devices, optically controlled microwave
`
`devices, such as phase shifters and attenuators, and high frequency semiconductor
`
`heterostructures. I also received a 1985-86 IBM Corporation Faculty Development
`
`Award to support my early work in advanced semiconductor devices.
`
`14. My research over the last forty years has concentrated heavily in the
`
`areas of electromagnetics, microwave and RF engineering, microelectronics,
`
`semiconductor devices, IC fabrication, and new sensors. This research work has
`
`been funded by many agencies, focusing on the fabrication and modeling of
`
`semiconductor devices, electromagnetic devices and detectors, chemical sensors,
`
`temperature sensors, proximity sensors, and pressure sensors, as well as research
`
`on the high frequency properties of transmission lines, RF devices, and infrared to
`
`terahertz detectors (both direct detectors and down-conversion mixers) for use in
`
`focal plane imaging arrays.
`
`15. My research related to the development of new chemical sensors (an
`
`“electronic taste” sensor) was selected for a commercialization venture between
`
`The University of Texas and two outside start-up companies.

`In 1985, I established the Microelectronics Fabrication Teaching
`
`16.
`
`Laboratory at The University of Texas at Austin, which continues to this day to
`
`provide undergraduate and graduate students with hands-on experience in IC
`
`fabrication. I have taught many courses in integrated-circuit fabrication,
`
`microwave devices, IC packaging, electromagnetics, computer aided design
`
`methods for circuit simulation, sensors of all sorts, and micro-electromechanical
`
`systems.
`
`17.
`
`In recognition of my research and classroom teaching
`
`accomplishments, I received the 1984-85 Engineering Foundation Faculty Award

`
`Through my work on sensors, electronic systems and innovations in
`
`other related fields, I have been named an inventor on 17 U.S. patents. These are
`
`summarized in my curriculum vitae.
`
`23. My issued patents include, for example, U.S. Patent No, 5,408,107,
`
`titled “Semiconductor Device Apparatus Having Multiple Current-Voltage Curves
`
`and Zero-Bias Memory.” This patent is directed to a semiconductor device that can
`
`be switched between current-voltage curve settings at higher positive or negative
`
`voltages and can be read at lower voltages.
`
`24. As another example, U.S. Patent No. 9,291,586, titled “Passive
`
`Wireless Self-Resonant Sensor,” relates to a sensor for detecting materials,
`
`including a substrate, a passivation layer formed on the substrate, a high surface
`
`area material disposed on the passivation layer, and a self-resonant structure that
`
`includes a planar spiral inductor and a plurality of planar interdigitated capacitor
`
`electrodes disposed within the passivation layer.
`

`
`III. PERSON OF ORDINARY SKILL IN THE ART
`
`31.
`
`I have been informed that the ’835 patent and its claims, as well as the
`
`prior art, are interpreted the way a hypothetical person having ordinary skill in the
`
`relevant art would have interpreted these materials at the time of the invention. I
`
`understand that the “time of the invention” in this IPR proceeding is the earliest
`
`“priority date” that the applicant for the ’835 patent claimed in the United States
`
`Patent & Trademark Office (“USPTO”). Here, the face of the patent indicates that
`
`the application claims priority to a provisional patent application filed January 28,
`
`10
`
`IPR2022-00246 Page 00018
`
`

`

`IPR2022-00246
`U.S. Patent No. 7,292,835
`2000. As mentioned above, I was conducting research in the relevant
`
`technological field at that time.
`
`32.
`
`In determining the characteristics of a person of ordinary skill in the
`
`art at the time of the claimed invention, I considered several things, including the
`
`factors discussed below, as well as (1) the levels of education and experience of the
`
`inventor and other persons actively working in the relevant field; (2) the types of
`
`problems encountered in the field; (3) prior art solutions to these problems; (4) the
`
`rapidity in which innovations are made; and (5) the sophistication of the relevant
`
`technology. I also placed myself back in the relevant time period and considered
`
`the individuals that I had worked with in the field.
`
`33.
`
`It is my opinion that a person having ordinary skill in the relevant art
`
`at the time of the invention (“POSITA”) would have been someone with at least an
`
`undergraduate degree in electrical engineering or a related subject and two or more
`
`years of experience in the fields of communication systems, signal processing
`
`and/or RF circuit design. Less work experience may be compensated by a higher
`
`level of education, such as a master’s degree.
`
`34.
`
`I understand that a person of ordinary skill in the relevant art is a
`
`hypothetical person who is assumed to be aware of all the pertinent information
`
`that qualifies as prior art. He or she is a person of ordinary creativity, not an
`
`automaton. He or she makes inferences and takes creative steps. In addition, a
`
`11
`
`IPR2022-00246 Page 00019
`
`

`

`IPR2022-00246
`U.S. Patent No. 7,292,835
`person of ordinary skill recognizes that prior art items may have obvious uses
`
`beyond their primary purposes, and in many cases he or she will be able to fit the
`
`teachings of multiple pieces of prior art together like pieces of a puzzle.
`
`35.
`
`I am prepared to testify as an expert in this field and also as someone
`
`who had at least the knowledge of a person having ordinary skill in the art at the
`
`time of the claimed invention, and someone who worked with others that had at
`
`least the knowledge of a person having ordinary skill in the art at the time of the
`
`alleged invention.
`
`36. Unless otherwise stated, my statements below refer to the knowledge,
`
`beliefs and abilities of a person having ordinary skill with respect to the arts
`
`relevant to the ’835 patent at the time of the claimed invention.
`
`IV. STANDARDS OF ANTICIPATION AND OBVIOUSNESS
`
`37.
`
`I offer no opinions on the law. However, I have developed an
`
`understanding of several legal principles regarding invalidity of patent claims, and
`
`other relevant legal issues. I have applied this understanding in arriving at my
`
`stated opinions and conclusions in this declaration.
`
`38.
`
`I understand that the ’835 patent contains independent and dependent
`
`claims. An independent claim is one that does not refer to other claims in the
`
`patent, and it must be read separately from the other claims to determine the scope
`
`of such a claim. On the other hand, a dependent claim refers to at least one other
`
`12
`
`IPR2022-00246 Page 00020
`
`

`

`IPR2022-00246
`U.S. Patent No. 7,292,835
`claim in the patent. Such a claim incorporates all of the elements of any claim to
`
`which the dependent claim refers, as well as the additional elements recited in the
`
`dependent claim itself.
`
`39.
`
`I understand that, for example in federal district court infringement
`
`actions, a claim in an issued patent is presumed to be valid. In such federal court
`
`actions, a patent claim can be “invalidated” upon a showing of clear and
`
`convincing evidence. This is not such an action.
`
`40. Rather, I understand that in an IPR proceeding like this one, the
`
`Petitioner(s) has the burden of proving a proposition of “unpatentability” by a
`
`“preponderance of the evidence.” I understand that preponderance of the evidence
`
`means the greater weight of evidence. In an IPR proceeding, the USPTO may
`
`cancel “as unpatentable” one or more claims of a patent on a ground that could be
`
`raised under section 102 or 103 of the Patent Act, and only on the basis of prior art
`
`consisting of patents or printed publications.
`
`41.
`
`I am informed that the patentability of the challenged claims in this
`
`proceeding are to be assessed under the pre-America Invents Act (“pre-AIA”)
`
`section 102 and 103 of the Patent Act. References to section 102 or 103 herein
`
`refer to the pre-AIA versions of those statutes.
`
`42.
`
`I understand that section 102 deals with the “novelty” of patent
`
`claims. I understand that under section 102(a), a person is not entitled to a patent
`
`13

`if, among other things, the invention was patented or described in a printed
`
`publication in this or a foreign country, before the invention thereof by the
`
`applicant for patent. Under section 102(b), a person is not entitled to a patent if,
`
`among other things, the invention was patented or described in a printed
`
`public
