`
`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 ’554 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
`
`-10-
`
`
`
`
`
`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.
`
`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 ¶20. I discuss the asserted level of skill further below, in Section VI of
`
`this declaration.
`
`-11-
`
`
`
`
`
`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
`
`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.
`
`-12-
`
`
`
`
`
`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 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 ’554 PATENT
`A. The ’554 Patent
`27. Masimo’s U.S. Patent No. 10,588,554 (“’554 Patent”) is generally
`
`directed to optical physiological sensor devices that use a combination of different
`
`design elements and improve optical detection efficiency. Masimo’s claims are
`
`directed to physiological measurement systems that include physiological sensor
`
`devices. These claims include at least four detectors, multiple emitters, and a cover
`
`with a protruding surface that works in conjunction with a wall to enhance the
`
`device’s effectiveness. The ’554 Patent explains that these different pieces work
`
`together to provide greater noise cancellation and an order of magnitude increase in
`
`signal strength. Ex. 1001 9:18-23, 20:14-30; see also 3:13-23, 4:16-27. For
`
`example, the ’554 Patent helps address issues related to light attenuation and errors
`
`resulting from the variations in the path of light passing through tissue. The ’554
`
`Patent identifies several different benefits to the use of a protrusion in conjunction
`
`with the physiological sensor device. For instance, the protrusion thins out a
`
`measurement site on the body, resulting in less light attenuation by a measured
`
`tissue for the physiological sensor device. Ex. 1001 7:46-51. The protrusion also
`
`further increases the area from which attenuated light can be measured. Ex. 1001
`
`7:51-53. The wall or housing may also play a role by allowing maximization of the
`
`amount of tissue-attenuated light that impinges on the detectors. Ex. 1001 36:35-
`
`-14-
`
`
`
`
`
`41. The multiple detectors in the physiological sensor device of the ’554 Patent
`
`allow for an averaging of measurements, and the averaging of measurements can
`
`reduce errors due to variations in the path of light passing through the tissue. Ex.
`
`1001 9:18-23; see also 3:13-23, 4:16-27.
`
`B.
`
`Introduction To The Independent Claims Of The ’554 Patent
`28.
`The ’554 Patent has two independent claims: claims 1 and 20. Claim
`
`1 reads as follows:
`
`A physiological measurement system comprising:
`
`a physiological sensor device comprising:
`
`a plurality of emitters configured to emit light into tissue of a user;
`
`at least four detectors, wherein each of the at least four detectors has a
`
`corresponding window that allows light to pass through to the
`
`detector;
`
`a wall that surrounds at least the at least four detectors; and
`
`a cover that operably connects to the wall and that is configured to be
`
`located between tissue of the user and the at least four detectors
`
`when the physiological sensor device is worn by the user,
`
`wherein:
`
`the cover comprises a single protruding convex surface, and
`
`-15-
`
`
`
`
`
`at least a portion of the cover is sufficiently rigid to cause tissue
`
`of the user to conform to at least a portion of a shape of
`
`the single protruding convex surface when
`
`the
`
`physiological sensor device is worn by the user; and
`
`a handheld computing device
`
`in wireless communication with
`
`the
`
`physiological sensor device, wherein the handheld computing device
`
`comprises:
`
`one or more processors configured to wirelessly receive one or more
`
`signals from the physiological sensor device, the one or more
`
`signals responsive to at least a physiological parameter of the
`
`user;
`
`a touch-screen display configured to provide a user interface,
`
`wherein:
`
`the user interface is configured to display indicia responsive to
`
`measurements of the physiological parameter, and
`
`an orientation of the user interface is configurable responsive to a user
`
`input; and
`
`a storage device configured to at least temporarily store at least the
`
`measurements of the physiological parameter.
`
`-16-
`
`
`
`
`
`29.
`
`Claim 20 reads as follows:
`
`A physiological measurement system comprising:
`
`a physiological sensor device comprising:
`
`a plurality of emitters configured to emit light into tissue of a
`
`user;
`
`at least four detectors, wherein each of the at least four
`
`detectors has a corresponding window that allows light to
`
`pass through to the detector;
`
`a wall that surrounds at least the at least four detectors; and
`
`a cover comprising a single protruding convex surface, wherein
`
`the single protruding convex surface is configured to be
`
`located between tissue of the user and the at least four
`
`detectors when the physiological sensor device is worn
`
`by the user, wherein at least a portion of the single
`
`protruding convex surface is sufficiently rigid to cause
`
`tissue of the user to conform to at least a portion of a
`
`shape of the single protruding convex surface when the
`
`physiological sensor device is worn by the user, and
`
`wherein the cover operably connects to the wall; and
`
`-17-
`
`
`
`
`
`a handheld computing device in wireless communication with the
`
`physiological sensor device.
`
`30. Dr. Kenny applies the same combination of references against claim 1
`
`(Ex. 1003 ¶¶111-195) and claim 20 (Ex. 1003 ¶¶216-236). Dr. Kenny’s analysis
`
`generally treats claims 1 and 20 similarly, and Dr. Kenny relies on and refers back
`
`to his analysis for claim 1 for his analysis of claim 20. Ex. 1003 ¶¶216-236. In
`
`addressing Dr. Kenny’s opinions, my analysis therefore likewise applies to claims 1
`
`and 20.
`
`V. THE PETITION’S PROPOSED COMBINATION
`Petitioner presents one ground that combines four references. Ground
`
`31.
`
`1 combines Mendelson ’799 (Ex. 1012), Ohsaki (Ex. 1009), Schulz (Ex. 1013), and
`
`Mendelson 2006 (Ex. 1010). Pet. 11-12. Ground 1 challenges claims 1-7 and 20-
`
`28.
`
`VI. LEVEL OF ORDINARY SKILL IN THE ART
`Petitioner asserts that a POSITA “would have been a person with a
`
`32.
`
`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
`
`-18-
`
`
`
`
`
`monitoring technologies.” Pet. 10-11. Alternatively, Petitioner asserts a POSITA
`
`could have “a Master of Science degree in a relevant academic discipline with less
`
`than a year of related work experience in the same discipline.” Pet. 10-11.
`
`33. Dr. Kenny states that he applies the same level of skill in his analysis
`
`stating that a POSITA “would have been 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 ¶20.
`
`34.
`
`I note that the asserted level of skill (1) requires no coursework,
`
`training or experience with optics or optical physiological monitors; (2) requires no
`
`coursework, training or experience in physiology; and (3) focuses on data
`
`processing and not sensor design. In responding to Dr. Kenny’s opinions in this
`
`proceeding, I apply Dr. Kenny’s and Petitioner’s asserted level of skill.
`
`35.
`
`In addition, as noted above, I understand that Dr. Kenny carried out
`
`his analysis of patentability as of July 3, 2008. Ex. 1003 ¶¶15, 22. In responding to
`
`-19-
`
`
`
`
`
`Dr. Kenny’s opinions, I also apply the July 3, 2008 date in my analysis. I do not
`
`offer any opinions regarding priority in this declaration.
`
`A.
`
`VII. GROUND 1 DOES NOT ESTABLISH OBVIOUSNESS
`Introduction To Ground 1
`36. Dr. Kenny’s combination for Ground 1 combines four references:
`
`Ohsaki, Mendelson ’799, Schulz, and Mendelson 2006. Ex. 1003 ¶¶81-271.
`
`1. Ohsaki Discloses A Pulse Rate Sensor With A Single Emitter And
`A Single Detector That Must Be Arranged Linearly On The Back
`Side Of The Wrist
`37. Ohsaki is directed to a pulse rate sensor with a single emitter (e.g., an
`
`LED) and a single detector disposed linearly, side-by-side, under a translucent
`
`“board.” See, e.g., Ex. 1009 Abstract, Fig. 2, ¶[0019]. Ohsaki explains that its
`
`linearly arranged detector and emitter (shown in the figures below) results in a
`
`longitudinal rectangular shape and direction, and Ohsaki explains this
