`
`I.
`QUALIFICATIONS
`2. My qualifications are set forth in my curriculum vitae, a copy of
`
`which is included as Exhibit 2005. A summary of my qualifications follows.
`
`3.
`
`I am a professor in Electrical and Computer Engineering at the
`
`Georgia Institute of Technology (“Georgia Tech”). I have worked in the area of
`
`digital signal processing, wireless communications, computer engineering,
`
`integrated circuit design, and software engineering for over 25 years, and have
`
`authored, co-authored, or edited several books and numerous peer-reviewed
`
`technical papers in these area.
`
`4.
`
`I obtained my Ph.D. in Electrical Engineering and Computer Science
`
`at the University of California, Berkeley, in 1989. While there, I received the
`
`-1-
`
`
`
`
`
`Demetri Angelakos Outstanding Graduate Student Award and the IEEE/ACM Ira
`
`M. Kay Memorial Paper Price.
`
`5.
`
`I joined Georgia Tech in the Fall of 1989 and am now a tenured full
`
`professor in Electrical and Computer Engineering. Among other things, I have
`
`been active in the areas of digital signal processing, wireless communications,
`
`integrated circuit design (analog & digital), system-level design methodologies and
`
`tools, and software engineering. I have been the principal investigator (“PI”) or
`
`co-PI in several active research programs in these areas, including DARPA’s
`
`Rapid Prototyping of Application Specific Signal Processors, the State of
`
`Georgia’s Yamacraw Initiative, the United States Army’s Federated Sensors
`
`Laboratory Program, and
`
`the United States Air Force Electronics Parts
`
`Obsolescence Initiative. I have received an IBM Faculty Award and NSF’s
`
`Research Initiation Award. I have been awarded the 2006 Frederick Emmons
`
`Terman Medal by
`
`the American Society of Engineering Education for
`
`contributions to Electrical Engineering, including authoring a widely used textbook
`
`in the design of VLSI digital signal processors.
`
`6.
`
`During the past 20 years at Georgia Tech, I have created and taught
`
`undergraduate and graduate courses in hardware and software design for signal
`
`processing, computer engineering (software and hardware systems), computer
`
`engineering and wireless communication circuits.
`
`-2-
`
`
`
`
`
`7.
`
`I have been involved in research and technology in the area of digital
`
`signal processing since the late 1980s, and I am the Editor-in-Chief of the CRC
`
`Press’s 3-volume Digital Signal Processing Handbook (1998, 2010).
`
`8.
`
`I have founded three companies in the areas of signal processing,
`
`embedded software, military chipsets involving imaging technology, and software
`
`for computing and communications systems. I have supervised Ph.D. dissertations
`
`of over twenty engineers in the areas of computer engineering, signal processing,
`
`communications, rapid prototyping, and system-level design methodology.
`
`9.
`
` I have designed several specialized computer and communication
`
`systems over the past two decades at Georgia Tech for tasks such as wireless audio
`
`and video processing and protocol processing for portable platforms, such as cell
`
`phones and PDAs. I have designed systems that are efficient in view of
`
`performance, size, weight, area, and thermal considerations. I have developed
`
`courses and classes for industry on these topics, and many of my lectures in
`
`advanced computer system design, developed under the sponsorship of the United
`
`States Department of Defense in the late 1990s, are available for educational use at
`
`http://www.eda.org/rassp and have been used by several U.S. and international
`
`universities as part of their course work. Some of my recent publications in the
`
`area of design of computer engineering and wireless communications systems and
`
`associated protocols are listed in Exhibit 2005.
`
`-3-
`
`
`
`
`
`10.
`
`In the mid 2006-2007 timeframe, I collaborated with Professor John
`
`Scharf and his colleagues at Emory Healthcare system in developing FFT-based
`
`pulse oximetry system prototypes on FPGAs, which extended technologies
`
`developed by Prof. Scharf and his colleagues from the 1996 time frame (See T.
`
`Rusch, R. Sankar, J. Scharf, “Signal Processing Methods for Pulse Oximetry”,
`
`Comput. Bio. Med, Vol. 26, No. 2, 1996). Some of my more recent publications in
`
`the area of biological signal processing and bioinformatics are listed in my CV and
`
`include, A. Bahga, V. Madisetti, “Healthcare Data Integration and Informatics in
`
`the Cloud”, IEEE Computer, Vol. 48, Issue 2, 2015, and “Cloud-Based
`
`Information Integration Informatics Framework for Healthcare Applications”,
`
`IEEE Computer, Issue 99, 2013. In addition to my signal processing experience
`
`specific to pulse oximetry, I also have experience in developing systems for other
`
`physiological signals. Beginning in the early 1990s, I worked, in particular, with
`
`ECG/EKG signals, and, in general, with biomedical signals and systems.
`
`11.
`
`In addition to my signal processing experience specific to pulse
`
`oximetry, I also have experience in developing algorithms and systems for other
`
`physiological signals. I worked with ECG/EKG signals in particular, and
`
`biomedical signals and systems in general, beginning in the early 1990s. In
`
`particular, I worked with graduate student Dr. Shahram Famorzadeh, in 1990 and
`
`1991, to analyze and apply pattern recognition (a category of signal processing
`
`-4-
`
`
`
`
`
`algorithms that is based on correlation with a set of templates) to ECG/EKG
`
`waveforms to identify physiological conditions.
`
`12.
`
`I have experience with biomedical signals and devices in the field of
`
`speech and image processing since the late 1980s. I worked on deconvolution
`
`algorithms to recover the state of the system based on observed measurements of
`
`the physiological signals in the 1993-1998 time-frame. These signal processing
`
`techniques can be applied to pulse oximetry signals, and I have been working with
`
`these techniques since the mid-1980s.
`
`13.
`
`I have studied, researched and published in the area of adaptive filter
`
`signal processing for noise reduction and signal prediction, using correlation-based
`
`approaches since the mid-1980s, both in the time-domain and frequency domain,
`
`and also to ray-tracing applications, such as Seismic Migration for oil and shale
`
`gas exploration. See for instance, V. Madisetti & D. Messerschmitt, Dynamically
`
`Reduced Complexity Implementation of Echo Cancellers, IEEE International
`
`Conference on Speech, Acoustics and Signal Processing, ICASSP 1986, Tokyo,
`
`Japan, and M. Romdhane and V. Madisetti, “All-Digital Oversampled Front-End
`
`Sensors” IEEE Signal Processing Letters, Vol. 3, Issue 2, 1996, and “LMSGEN: A
`
`Prototyping Environment for Programmable Adaptive Digital Filters in VLSI”,
`
`VLSI Signal processing, pp. 33-42, 1994.
`
`-5-
`
`
`
`
`
`14. Deconvolution of symmetric (seismic) and asymmetric (pulse
`
`oximetry) signals has gained much importance in the past two decades, and some
`
`of my early work on “Homomorphic Deconvolution of Bandpass Signals” in IEEE
`
`Transactions on Signal Processing, October 1997, established several new methods
`
`for deconvolution of such signals that had several advantages of robustness,
`
`increased accuracy, and simplicity.
`
`15.

`
`area of computer systems, instruments, and software design, and these include:

`
`III. UNDERSTANDING OF PATENT LAW
`I am not an attorney and will not be offering legal conclusions.
`
`18.
`
`However, I have been informed of several principles concerning the legal issues
`
`relevant to analyzing the challenges to the claims of the ’628 Patent, and I used
`
`these principles in arriving at my conclusions.
`
`A. Level Of Ordinary Skill In The Art
`19.
`I understand that certain issues in an IPR, such as claim construction
`
`and whether a claim is invalid as obvious, are assessed from the view of a
`
`hypothetical person of ordinary skill in the relevant art at the time of the invention.
`
`I understand there are multiple factors relevant to determining the level of ordinary
`
`skill in the art, including (1) the level of education and experience of persons
`
`working in the field at the time of the invention; (2) the sophistication of the
`
`technology; (3) the types of problems encountered in the field; and (4) the prior art
`
`solutions to those problems. I understand that this hypothetical person of ordinary
`
`skill is presumed to have had knowledge from the teachings of the prior art.
`
`-10-
`
`
`
`
`
`20.
`
`I understand that Apple Inc. (“Apple” or “Petitioner”) and its
`
`Declarant Dr. Kenny have set forth the following definition for a person of
`
`ordinary skill in the art (“POSITA”): “someone with a working knowledge of
`
`physiological monitoring technologies. The person would have had a Bachelor of
`
`Science degree in an academic discipline emphasizing the design of electrical,
`
`computer, or software technologies, in combination with training or at least one to
`
`two years of related work experience with capture and processing of data or
`
`information, including but not limited to physiological monitoring technologies.
`
`Alternatively, the person could have also had a Master of Science degree in a
`
`relevant academic discipline with less than a year of related work experience in the
`
`same discipline.” Ex. 1003 ¶21. I discuss the asserted level of skill further below,
`
`in Section VI of this declaration.
`
`B. Claim Construction
`21.
`I understand that claim construction in an IPR is a legal question for
`
`the Board to decide. I also understand, however, that in construing claim terms,
`
`the Board asks what the terms would mean to a person of ordinary skill in the
`
`relevant art in view of the disclosures in the patent and the prosecution history of
`
`the patent. I understand that the Board may also consider external evidence, such
`
`as dictionaries. In general, however, I understand that claim terms are given the
`
`-11-
`
`
`
`
`
`ordinary and customary meaning one of ordinary skill in the relevant art would
`
`apply to them in the context of the patent at the time the patent was filed.
`
`22.
`
`I understand that Apple did not identify any terms for construction. I
`
`have given the claim terms their plain and ordinary meaning in my analysis.
`
`C. Obviousness
`23.
`I understand that a patent claim is invalid under the patent law, 35
`
`U.S.C. § 103, if, at the time the claimed invention was made, the differences
`
`between the prior art and the claimed invention as a whole would have been
`
`obvious to a person of ordinary skill in the art. I understand that the following
`
`facts are considered in determining whether a claimed invention is invalid as
`
`obvious in view of the prior art: (1) the scope and content of the prior art; (2) the
`
`level of ordinary skill in the art; and (3) the differences, if any, between the
`
`claimed invention and the prior art.
`
`24.
`
`I also understand there are additional considerations that may be used
`
`in evaluating whether a claimed invention is obvious. These include whether the
`
`claimed invention was the result of (a) a teaching, suggestion, or motivation in the
`
`prior art that would have led one of ordinary skill to modify the prior art to arrive
`
`at the claimed invention; (b) a combination of prior art elements combined
`
`according to known methods to yield predictable results; (c) a simple substitution
`
`of one known element for another to obtain a predicable result; (d) the use of a
`
`-12-
`
`
`
`
`
`known technique to improve similar things in the same way; (e) applying a known
`
`technique to a known thing ready for improvement to yield predictable results; (f)
`
`choosing from a finite number of identified, predictable solutions, with a
`
`reasonable expectation of success; (g) known work in one field of endeavor
`
`prompting variations of it for use in either the same filed or a different one based
`
`on design incentives or other market forces if the variations are predictable to one
`
`of ordinary skill in the art.
`
`25.
`
`26.
`
`I have applied this understanding in my analysis.
`
`I understand that Dr. Kenny carried out his analysis of patentability as
`

`INTRODUCTION TO MASIMO’S TECHNOLOGY
`A. The ’628 Patent
`27. Masimo’s U.S. Patent No. 10,292,628 (the “’628 Patent”) is generally
`
`directed to optical physiological measurement sensors and devices that use a
`
`combination of different design elements to improve detection efficiency.
`
`Masimo’s claimed non-invasive optical physiological measurement sensor or
`
`device includes multiple detectors, multiple emitters, and a cover with a protruding
`
`surface that together enhance the sensor’s or device’s effectiveness. The ’628
`
`Patent explains that these different components work together to provide greater
`
`-13-
`
`
`
`
`
`noise cancellation and an order of magnitude increase in signal strength. Ex. 1001
`
`9:7-12, 20:4-20; see also 3:6-16, 4:8-18. Among other things, the ’628 Patent
`
`helps address problems of light attenuation and errors due to the variations in the
`
`path of light passing through tissue. The ’628 Patent identifies several different
`
`benefits to the use of a protruding surface. For example, the protruding surface
`
`thins out a measurement site, resulting in less light attenuation by a measured
`
`tissue. Ex. 1001 7:38-41. The protruding surface further increases the area from
`
`which attenuated light can be measured. Ex. 1001 7:41-43. The multiple detectors
`
`in the sensor or device of the ’628 Patent allow for an averaging of measurements,
`
`which can, in turn, reduce errors due to variations in the path of light passing
`
`through the tissue. Ex. 1001 9:7-12; see also 3:6-16, 4:8-18.
`
`B.
`
`Introduction To The Independent Claims Of The ’628 Patent
`28. The ’628 Patent has three independent claims: claims 1, 7, and 20.
`
`Claims 1, 7, and 20 each claim a noninvasive optical physiological measurement
`
`sensor or device that includes, among other things, (1) a plurality of emitters, (2) at
`
`least four detectors, and (3) either a cover that comprises a protruding surface and
`
`is configured to be located between tissue of the user and the plurality of detectors
`
`(claims 1 and 20) or a cover comprising a protruding surface that is arranged to
`
`allow passage of light to the at least four detectors (claim 7).
`
`-14-
`
`
`
`
`
`29. Claim 1 requires a light permeable cover comprising an outwardly
`
`protruding convex surface through which the plurality of detectors are configured
`
`to receive light. Claim 1 reads:
`
`1. A noninvasive optical physiological sensor comprising:
`
`a plurality of emitters configured to emit light into tissue of a
`
`user;
`
`a plurality of detectors configured to detect light that has been
`
`attenuated by tissue of the user, wherein the plurality of detectors
`
`comprise at least four detectors;
`
`a housing configured to house at least the plurality of detectors;
`
`and
`
`a light permeable cover configured to be located between tissue
`
`of the user and the plurality of detectors when the noninvasive optical
`
`physiological sensor is worn by the user, wherein the cover comprises
`
`an outwardly protruding convex surface configured to cause tissue of
`
`the user to conform to at least a portion of the outwardly protruding
`
`convex surface when the noninvasive optical physiological sensor is
`
`worn by the user and during operation of the noninvasive optical
`
`physiological sensor, and wherein the plurality of detectors are
`
`-15-
`
`
`
`
`
`configured to receive light passed through the outwardly protruding
`
`convex surface after attenuation by tissue of the user.
`
`30. Claim 7 requires a light permeable cover comprising wherein at least
`
`a portion of the cover comprises a protruding surface that is arranged to allow
`
`passage of light to at least four detectors. Claim 7 reads:
`
`7. An optical physiological measurement device comprising:
`
`a plurality of emitters configured to emit light into tissue of a
`
`user;
`
`a circular housing including a planar surface;
`
`at least four detectors arranged on the planar surface of the
`
`circular housing, wherein the four detectors are arranged in a grid
`
`pattern; and
`
`a light permeable cover of the circular housing, and wherein at
`
`least a portion of the cover comprises a protruding surface that is
`
`arranged to allow passage of light to the at least four detectors after
`
`attenuation by tissue of the user.
`
`31. Claim 20 requires a light permeable cover comprising an outwardly
`
`protruding convex surface through which the plurality of detectors are configured
`
`to receive light. Claim 20 reads:
`
`20. A noninvasive optical physiological sensor comprising:
`
`-16-
`
`
`
`
`
`user;
`
`a plurality of emitters configured to emit light into tissue of a
`
`a plurality of detectors configured to detect light that has been
`
`attenuated by tissue of the user, wherein the plurality of detectors
`
`comprise at least four detectors;
`
`a housing configured to house at least the plurality of detectors;
`
`and
`
`a light permeable cover configured to be located between tissue
`
`of the user and the plurality of detectors when the noninvasive optical
`
`physiological sensor is worn by the user, wherein the cover comprises
`
`an outwardly protruding surface configured to cause tissue of the user
`
`to conform to at least a portion of the outwardly protruding surface
`
`when the noninvasive optical physiological sensor is worn by the user
`
`and during operation of the noninvasive optical physiological sensor,
`
`and wherein the outwardly protruding surface is further configured to
`
`allow passage of light to the plurality of detectors after attenuation by
`
`tissue of the user.
`
`32. Dr. Kenny applies the same combination of references against claim 1
`
`(Ex. 1003 ¶¶72-98, 142-146, 171-186), claim 7 (Ex. 1003 ¶¶108-115, 142-146,
`
`198-205), and claim 20 (Ex. 1003 ¶¶130-134, 142-146, 216-220). Dr. Kenny’s
`
`-17-
`
`
`
`
`
`analysis generally treats claims 1, 7, and 20 similarly, and Dr. Kenny relies on and
`
`incorporates his analysis for claim 1 into his analysis of claims 7 and 20. Ex. 1003
`
`¶¶108-115, 130-134, 146, 171-186, 198-205, 216-220. In addressing Dr. Kenny’s
`
`opinions, my analysis therefore likewise applies to claims 1, 7, and 20.
`
`V. THE PETITION’S PROPOSED COMBINATIONS
`33. Petitioner presents six grounds. Grounds 1A-1D (the “Aizawa
`
`grounds”) combine at least Aizawa (Ex. 1006) and Inokawa (Ex. 1007, translation
`
`at Ex. 1008). Pet. 1-2.
`
` Ground 1A combines Aizawa and Inokawa. Ground 1A challenges
`
`claims 1-15, 17, 20-26, and 28.
`
` Ground 1B adds Ohsaki (Ex. 1014) to the combination of Aizawa and
`
`Inokawa. Petitioner characterizes Ohsaki as providing an additional
`
`motivation and rationale to modify Aizawa to add a light permeable
`
`cover comprising a protrusion. Pet. 45. Ground 1B challenges claims
`
`1-15, 17, 20-26, and 28.
`
` Ground 1C combines Aizawa, Inokawa, Mendelson-2006 (Ex. 1016),
`
`and Beyer (Ex. 1019). Ground 1C challenges claims 18, 19, 29, and
`
`30.
`
` Ground 1D combines Aizawa, Inokawa, Goldsmith (Ex. 1027), and
`
`Lo (Ex. 1028). Ground 1D challenges claims 18, 19, 29,, and 30.
`
`-18-
`
`
`
`
`
`34. Grounds 2A-2B (the “Mendelson grounds”) combine at
`
`least
`
`Mendelson-1988 (Ex. 1015) and the same Inokawa reference used in Grounds 1A-
`
`1D. Pet. 2.
`
` Ground 2A combines Mendelson-1988 and Inokawa. Ground 2A
`
`challenges claims 1-17 and 20-28.
`
` Ground 2B combines Mendelson-1988, Inokawa, Mendelson-2006,
`
`and Beyer. Mendelson-2006 and Beyer are the same Mendelson-2006
`
`and Beyer references used in Ground 1C. Ground 2B challenges
`
`claims 18, 19, 29, and 30.
`
`35. Aizawa and Mendelson-1988 share the same general arrangement of
`
`peripheral detectors positioned radially around a central light source. Ex. 1006
`
`Fig. 1A; Ex. 1015 Figs. 2A-B. In contrast, Inokawa arranges two LEDs on the
`
`outside edge of its sensor and one detector in the center of the sensor. Ex. 1008
`
`Fig. 2. I understand that Petitioner asserts a person of ordinary skill in the art
`
`would have incorporated Inokawa’s convex lens into Aizawa or Mendelson-1988’s
`
`sensor with the motivation to “increase the light collection efficiency.” Pet. 15, 64.
`
`As I discuss below, a POSITA would have not incorporated Inokawa’s convex lens
`
`into Aizawa or Mendelson-1988’s sensor with the motivation to “increase the light
`
`collection efficiency” because a POSITA would have understood that Inokawa’s
`
`convex lens would collect incoming light towards the center of the sensor. Unlike
`
`-19-
`
`
`
`
`
`Inokawa, which has its detector in the center, between an emitter on either side,
`
`Aizawa and Mendelson-1988 have detectors placed at the edge (or periphery) of
`
`the sensor. Thus, a POSITA would have believed that Inokawa’s convex lens,
`
`which was designed to concentrate light at the center-located detector and increase
`
`the optical signal, would have the opposite effect when used with Aizawa or
`
`Mendelson-1988’s peripherally located detectors and would decrease the light
`
`collection efficiency of the sensor.
`
`VI. LEVEL OF ORDINARY SKILL IN THE ART
`36. Petitioner asserts that a POSITA “would have been a person with a
`
`working knowledge of physiological monitoring technologies. The person would
