`APPLE 1073
`Apple v. AliveCor
`IPR2021-00972
`
`
`
`
`
` 1112
`
`
` 1 analysis this morning.
`
` 2 JUDGE ELLIOT: That's right. Thank you. Now I
`
` 3 remember. Very good. All right.
`
` 4 We're on the public record. And I'm waiting for
`
` 5 Dr. Stultz.
`
` 6 Good morning Dr. Stultz. Let me remind you
`
` 7 you're still under oath.
`
` 8 COLLIN STULTZ,
`
` 9 having been previously duly sworn and/or
`
` 10 affirmed on his oath, was thereafter examined and testified
`
` 11 further as follows:
`
` 12 DIRECT EXAMINATION (resumed)
`
` 13 BY MR. AMON:
`
` 14 Q. Good morning, Dr. Stultz. I'd like to now start
`
` 15 with your obviousness analysis.
`
` 16 If we could bring up RDX-3.39.
`
` 17 What framework did you use in analyzing your --
`
` 18 whether the Asserted Patents are invalid for obviousness?
`
` 19 A. So the framework I use is as illustrated on this
`
` 20 slide. There were four steps in the process.
`
` 21 First, to determine the scope and content of the
`
` 22 prior art, and to understand differences between that art
`
` 23 and the patent claim, and all of this is done within the
`
` 24 context of the person of ordinary skill in the art at the
`
` 25 time, and then, lastly, there were specific secondary
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`2
`
`
`
`
`
` 1113
`
`
` 1 considerations presented, is my understanding, by AliveCor,
`
` 2 and the question there is whether those considerations
`
` 3 affected my view.
`
` 4 Q. Dr. Stultz, what is Apple's burden in proving
`
` 5 that the Asserted Patents are invalid?
`
` 6 A. It is my understanding that it must be shown by
`
` 7 clear and convincing evidence.
`
` 8 Q. And just to backtrack for one second, is it your
`
` 9 understanding that Apple's burden is clear and convincing
`
` 10 for the patent-ineligible subject matter as well?
`
` 11 A. That is my understanding.
`
` 12 Q. If we go to RDX-3.40. What is this timeline,
`
` 13 Dr. Stultz?
`
` 14 A. So this timeline includes the relevant dates for
`
` 15 the patents in question, and it also outlines, briefly,
`
` 16 papers that represent the state of the art at the time.
`
` 17 So just -- I'm sorry to interrupt, but just to
`
` 18 expand upon that a little bit.
`
` 19 When I began this process, what I did was sit in
`
` 20 front of my computer and do a literature search setting the
`
` 21 time frame to 2013, which is the earliest date for the '499
`
` 22 and '731 patents, and then gathered the papers, and I think
`
` 23 there were maybe 50 to a hundred papers that were -- and
`
` 24 then reviewed those data.
`
` 25 And I think what was known at the time and the
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`3
`
`
`
`
`
` 1114
`
`
` 1 work going on at the time is well encapsulated by these four
`
` 2 references in green.
`
` 3 MR. AMON: For the record, Your Honor, the
`
` 4 references that Dr. Stultz is referring to are RX-560,
`
` 5 RX-562, RX-554, and RX-563.
`
` 6 Q. Dr. Stultz, if we go to RDX-3.41, what is on this
`
` 7 slide here?
`
` 8 A. So this are the three primary references that I
`
` 9 rely on for my obviousness argument. There is AMON 2004 and
`
` 10 then there are two additional references, Kotzin, which was
`
` 11 published in 2004, and Almen published in 2008.
`
` 12 Q. Let me pause there for a second.
`
` 13 MR. AMON: Your Honor, I think there was a little
`
` 14 feedback. I don't know if you heard that.
`
` 15 (Clarification by reporter.)
`
` 16 JUDGE ELLIOT: I'm sorry. I was muted. I was
`
` 17 actually trying to say something and I was muted. I don't
`
` 18 know who that was, but, if you're not on video, please mute
`
` 19 yourself.
`
` 20 MR. AMON: For the record, Your Honor, the AMON
`
` 21 reference is RX-419, the Almen reference is RX-400, and the
`
` 22 Kotzin reference is 401.
`
` 23 What is the date of the AMON reference?
`
` 24 A. The AMON reference is December 2004.
`
` 25 Q. What is the date of the Almen reference?
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`4
`
`
`
`
`
` 1115
`
`
` 1 A. That's also in December of 2008.
`
` 2 Q. And, finally, what is the date of the Kotzin
`
` 3 reference?
`
` 4 A. That was February 2004.
`
` 5 Q. If we go to RDX-3.42. What does the AMON
`
` 6 reference disclose?
`
` 7 A. So Amon describes a wearable medical monitoring
`
` 8 alert system, particularly targeting high-risk cardiac
`
` 9 respiratory patients.
`
` 10 The interesting thing here is that this is a
`
` 11 wrist-worn device that encompasses multiple sensors, sensors
`
` 12 including SpO2, blood pressure, and ECG.
`
` 13 Q. Just so that the record is clear, does an SpO2
`
` 14 sensor include a PPG?
`
` 15 A. That's right. So SpO2 technology is based on PPG
`
` 16 technology. Indeed, PPG gives you changes in the blood
`
` 17 volume in a particular vascular bed, so it sort of gives you
`
` 18 an estimate of the pulse rate. And the SpO2 builds on that
`
` 19 technology by incorporating different light sensors that
`
` 20 allow you to estimate the oxygenation in the corresponding
`
` 21 blood.
`
` 22 Q. If we go to RDX-3.43, was the AMON reference
`
` 23 cited by others in the field before May of 2015?
`
` 24 A. So in my literature search, I found one paper
`
` 25 that was listed on the left that specifically references
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`5
`
`
`
`
`
` 1116
`
`
` 1 AMON. And in this paper they talk about a smartphone app
`
` 2 that combines information from multiple sensors to aid with
`
` 3 clinical restratisfication and decision-making.
`
` 4 And they say specifically their solution is
`
` 5 similar to AMON and analyses and -- and other things,
`
` 6 analysis of ECG on a local device.
`
` 7 The second reference is on the right, and in this
`
` 8 reference they referred to the AMON prototype as being
`
` 9 innovative. I think the only point here is to say that AMON
`
` 10 published in 2004 was noted by others in a way that it
`
` 11 suggests, at least from my read of these data, that it was
`
` 12 inspiring.
`
` 13 MR. AMON: And for the record, Your Honor, the
`
` 14 additional reference cited here is RX-420.
`
` 15 Q. If we go to RDX-3.44, what does the Almen
`
` 16 reference disclose?
`
` 17 A. So Almen, A-L-M-E-N, also refers to a wrist-worn
`
` 18 device. It can be an armband as well. And the particular
`
` 19 thing about Almen is that it focuses on optical sensing to
`
` 20 measure heart rate variability for a variety of different --
`
` 21 I think the term they use is cardiac maladies.
`
` 22 Q. And if we go to RDX-3.45, what does the Kotzin
`
` 23 reference disclose?
`
` 24 A. So Kotzin discloses a portable communication
`
` 25 device that can have one or more sensors. And the thing
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`6
`
`
`
`
`
` 1117
`
`
` 1 here is it describes a system for communication between the
`
` 2 sensors and for relaying information from the sensors to the
`
` 3 user.
`
` 4 Q. So let's go to RDX-3.46. We're going to start
`
` 5 your obviousness analysis with the '941 patent.
`
` 6 Can you remind the Court the priority date for
`
` 7 the '941 patent, please?
`
` 8 A. That was in May 2015.
`
` 9 Q. Now looking at the limitations of claim 12 of the
`
` 10 '941, do you understand that there are certain limitations
`
` 11 that AliveCor does not dispute were disclosed by the AMON
`
` 12 reference?
`
` 13 A. That's my understanding.
`
` 14 Q. Which are those limitations?
`
` 15 A. Those are the limitations listed in A, B, C, and
`
` 16 D on this slide.
`
` 17 Q. In your opinion, Dr. Stultz, does the AMON
`
` 18 reference disclose limitations A, B, C, and D of claim 12 of
`
` 19 the '941?
`
` 20 A. Yes, it does.
`
` 21 Q. So what is the first limitation that AliveCor
`
` 22 contests from claim 12 of the '941 as we can see on this
`
` 23 slide?
`
` 24 A. It's the preamble, a smart watch comprising.
`
` 25 Q. If we go to RDX-3.47, does the AMON reference
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`7
`
`
`
`
`
` 1118
`
`
` 1 disclose a smart watch?
`
` 2 A. So, it's interesting, because the reference
`
` 3 explicitly discloses a wrist-worn device that is able to
`
` 4 show time and compares it to other computerized watches, and
`
` 5 that includes these different sensors. At the very least
`
` 6 it's a prototype for a smart watch. And, in my view, in
`
` 7 2004 it certainly would be considered a smart watch.
`
` 8 Q. If we go to RDX-3.48, does AliveCor next contest
`
` 9 limitation (e) of claim 12 of the '941?
`
` 10 A. That is my understanding.
`
` 11 Q. And it's a lengthy limitation, so let's look at
`
` 12 it in your analysis, if we go to RDX-3.49.
`
` 13 In your opinion does the AMON reference disclose
`
` 14 a non-transitory computer-readable storage medium encoded
`
` 15 with a computer program including instructions executable by
`
` 16 the processor?
`
` 17 A. In my view it does. Non-transitory
`
` 18 computer-readable storage medium is essentially a mechanism
`
` 19 for short-term storage. And AMON specifically discloses, if
`
` 20 you look on the left-hand side of this slide, in this
`
` 21 diagram, flash memory, it says it has four megabytes of
`
` 22 flash memory, additional 136 of on-chip additional memory,
`
` 23 SRAM, for program and data storage.
`
` 24 Q. And does it include -- does the AMON reference
`
` 25 disclose instructions?
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`8
`
`
`
`
`
` 1119
`
`
` 1 A. Oh, yes, it does. And the SRAM chip is
`
` 2 specifically for programming data storage.
`
` 3 Q. If we go to RDX-3.50, does the AMON reference
`
` 4 disclose determining if a discordance is present between the
`
` 5 activity level value of the user and the heart rate
`
` 6 parameter of the user?
`
` 7 A. So this is quite interesting. So Amon tries to
`
` 8 identify high-risk zones given observations of patient data.
`
` 9 So the observations include the pulse rate, and
`
` 10 it tries to determine a high-risk zone based on settings.
`
` 11 And that is illustrated here in table 1.
`
` 12 The key point here is that the settings are
`
` 13 determined by the activity level, and that we see in the
`
` 14 text on the left-hand side; namely, AMON is capable of
`
` 15 detecting the level of user activity and correlating it with
`
` 16 vital signs. Moreover, it specifies pulse limits are set
`
` 17 according to the activity level, walking, running or
`
` 18 resting.
`
` 19 So the high-risk areas are -- signify when the
`
` 20 parameters are inconsistent with the activity level.
`
` 21 Q. In your opinion, does that disclose a
`
` 22 discordance?
`
` 23 A. Yes, it is, because the settings -- it's
`
` 24 particularly high risk because it's inconsistent with that
`
` 25 activity level.
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`9
`
`
`
`
`
` 1120
`
`
` 1 Q. If we go to RDX-3.51, does the AMON reference
`
` 2 disclose that based on the presence of a discordance it
`
` 3 indicates possible arrhythmia?
`
` 4 A. Right. So I think using the terminology that --
`
` 5 of arrhythmia given in the Court, the things that are --
`
` 6 that can -- faster or slower than normal can potentially be
`
` 7 arrhythmias.
`
` 8 In this high-risk zone, and if you look here in
`
` 9 table 1, and the normal values are at rest, so a pulse rate
`
` 10 of 121 to 180 would have been considered to be a high risk,
`
` 11 abnormal, and that fits within the Court's definition of
`
` 12 an -- at least a potential arrhythmia.
`
` 13 Q. To the extent that the AMON reference does not
`
` 14 expressly disclose indicating the arrhythmia, would it have
`
` 15 been obvious to a person of ordinary skill that they could
`
` 16 take -- use the information from the AMON reference, modify
`
` 17 it, and determine a discordance -- an arrhythmia based on a
`
` 18 discordance? Excuse me.
`
` 19 A. I think using the definition, that's right, of an
`
` 20 arrhythmia, certainly events when the heart rate is higher.
`
` 21 In 2013, I think individuals first in this space would have
`
` 22 been working closely or at least have interactions with
`
` 23 health care professionals, and I think these concepts would
`
` 24 not have been alien to such an individual.
`
` 25 Q. Would the same have been true by May of 2015?
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`10
`
`
`
`
`
` 1121
`
`
` 1 A. That is my view.
`
` 2 Q. If we go to RDX-3.52, does the AMON reference
`
` 3 disclose receiving electric signals of the user from the ECG
`
` 4 sensor to confirm the presence of the arrhythmia?
`
` 5 A. Yes, it does. So if you look at the middle, the
`
` 6 verbiage in the middle portion of this slide, it says,
`
` 7 parameter out of range, remeasurement is performed, if the
`
` 8 outcome is the same as before, the user is informed
`
` 9 additional measurements are required, but one of the
`
` 10 measurements can be the ECG.
`
` 11 Q. If we go to RDX-3.53, in your opinion does the
`
` 12 Kotzin reference also disclose receiving electric signals of
`
` 13 the ECG to confirm the presence of the arrhythmia?
`
` 14 A. Yeah, I think that's the case. So Kotzin talks
`
` 15 about different sensors and characteristics. I think in the
`
` 16 actual reference they say sensors, they mean biosensors.
`
` 17 And communication between these sensors, if one of them is
`
` 18 determined to be unfavorable, meaning outside of the range
`
` 19 of some threshold, then an alert is sent to the user to
`
` 20 perform a specific action. That action can be measuring a
`
` 21 different characteristic, i.e., from a different -- from a
`
` 22 different sensor.
`
` 23 Q. Dr. Stultz, did you hear Dr. Picard's testimony
`
` 24 regarding how a person of ordinary skill would have
`
` 25 understood what it means to confirm the presence of the
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`11
`
`
`
`
`
` 1122
`
`
` 1 arrhythmia?
`
` 2 A. Yes, I did.
`
` 3 Q. Did you also hear Dr. Jafari's testimony about
`
` 4 what it means to confirm the presence of the arrhythmia?
`
` 5 A. Yes, I did.
`
` 6 Q. Do you agree with how Dr. Picard understands that
`
` 7 confirming limitation of claim 12 of the '941?
`
` 8 A. I do.
`
` 9 Q. If the Court accepts Dr. Jafari's understanding
`
` 10 of the plain and ordinary meaning of confirming, does that
`
` 11 impact your invalidity analysis?
`
` 12 A. So I think two points are relevant here. One,
`
` 13 the AMON reference describes both intermittent ECG
`
` 14 measurements in addition to continuous ECG measurements. So
`
` 15 I think both are encapsulated in this reference.
`
` 16 The other point is the definition supplied by
`
` 17 Dr. Jafari, with all due respect, is a little unclear to me.
`
` 18 So that has to be -- that proviso has to be attached to my
`
` 19 response.
`
` 20 Q. Does the AMON reference disclose simultaneous
`
` 21 measurements between PPG and ECG, in your opinion?
`
` 22 A. I'm sorry. Can you repeat the question?
`
` 23 Q. Sure. In your opinion, does the AMON reference
`
` 24 disclose simultaneous measurements of PPG and ECG data?
`
` 25 A. Yes, it does. It specifically discloses two
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`12
`
`
`
`
`
` 1123
`
`
` 1 scenarios where PPG and ECG can be measured continuously and
`
` 2 simultaneously. It even says that this is done, at least I
`
` 3 think, three times throughout the day. It also states that
`
` 4 some of these measurements, including the ECG measurements,
`
` 5 can be done intermittently.
`
` 6 Q. RDX-3.54, in your opinion does the AMON reference
`
` 7 alone or in combination with Kotzin disclose all the
`
` 8 requirements of claim 12?
`
` 9 A. Yes, it does.
`
` 10 Q. So if we go to RDX-3.55, and start looking at the
`
` 11 dependent claims, what does claim 13 require in addition to
`
` 12 claim 12?
`
` 13 A. So claim 13 recites, the smart watch or wristlet
`
` 14 according to claim 12, wherein the heart rate parameter
`
` 15 comprises an indication of a heart rate variability and
`
` 16 wherein the arrhythmia is atrial fibrillation.
`
` 17 Q. And if we go to RDX-3.56, in your opinion does
`
` 18 the AMON reference render calculating HRV obvious?
`
` 19 A. Yes, it does. AMON specifically discloses the
`
` 20 measurement of R-R distances, which really is equivalent to
`
` 21 the instantaneous heart rate. And I think we've heard
`
` 22 before in this -- in the last few days the R-R distances and
`
` 23 how they are calculated from the ECG.
`
` 24 So it -- I mean, in 2013 and 2015 were relevant
`
` 25 for this particular patent. It would have been a knee-jerk
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`13
`
`
`
`
`
` 1124
`
`
` 1 reaction, I think, for persons skilled in the art to see R-R
`
` 2 distances and to think about heart rate variability
`
` 3 calculations.
`
` 4 Q. Dr. Stultz, do you understand that the '941 is
`
` 5 talking about calculating HRV from the PPG signal?
`
` 6 A. That is my understanding.
`
` 7 Q. And, in your opinion, would a person of ordinary
`
` 8 skill in May of 2015 have found it obvious to modify the
`
` 9 AMON reference to calculate R-R from the PPG data?
`
` 10 A. Yes, I think that's true. There's scholarship
`
` 11 that speaks to this. There was works known beforehand that
`
` 12 HRV could be calculated from the PPG. There have been works
`
` 13 comparing PPG or R-R distances versus ECG. So, yes, I think
`
` 14 it would have been obvious.
`
` 15 Q. And if we go to RDX-3.57, did we see this slide
`
` 16 during Dr. Jafari's presentation?
`
` 17 A. It's my recollection that this was -- Dr. Jafari
`
` 18 showed this slide during his presentation.
`
` 19 Q. And what did Dr. Jafari explain using this slide?
`
` 20 A. So here on this slide is, on the right-hand side,
`
` 21 this is a waveform arising from a PPG, PPG signal. And the
`
` 22 distance between the peaks are labeled as R-R intervals.
`
` 23 And I agree with Dr. Jafari in this sense that,
`
` 24 although R-R intervals, specifically the term refers to R
`
` 25 waves within the electrocardiogram, that individuals skilled
`
`
`
`
`
`
`Heritage Reporting Corporation
`(202) 628-4888
`
`14
`
`
`
`
`
` 1125
`
`
` 1 in the art at the time and now thought about calculating or
`
` 2 would have considered calculating such interval lengths from
`
` 3 the PPG as representative of R-R intervals.
`
` 4 Q. Was this concept known in May of 2015?
`
` 5 A. Yes, it was.
`
` 6 Q. Was this concept known in December of 2013?
`
` 7 A. In my view it was, yes.
`
` 8 Q. And based on your training and education, was
`
` 9 this concept known in 2004 when the AMON reference
`
` 10 published?
`
` 11 A. I think that this work was around, that's
`
` 12 correct. Certainly most of the published work in this
`
` 13 happened a little after 2004, at least the papers that I can
`
` 14 recall, but certainly by 2013 and by 2015 this was
`
` 15 well-known.
`
` 16 Q. If we go to RDX-3.58, would the AMON reference
`
` 17 have rendered obvious the arrhythmia being atrial
`
` 18 fibrillation?
`
` 19 A. So I think, again, the key operative term here is
`
` 20 to a person skilled in the art. Again, someone who is
`
` 21 working in this area. And the concept of recognizing a
`
` 22 heart rate that is elevated, resting -- in the resting
`
` 23 state, as suggesting arrhythmia is, I think is -- would have
`
` 24 been known.
`
` 25 A case in point, in the '941 patent there is an
`
`
`
`

`
`
` 1 example given, I think it's from a tracing, that's what that
`
` 2 0302 refers to, that's my recollection, where the heart rate
`
` 3 rapidly increases, and that also being consistent with
`
` 4 atrial fibrillation. That's really shown as an example to
`
` 5 illustrate the point.
`
` 6 Q. If we go to RDX-3.59, to the extent that the AMON
`
` 7 reference does not disclose HRV or atrial fibrillation, did
`
` 8 Almen disclose those additional requirements of claim 13?
`
` 9 A. Yes, it did. So Almen, again, specifically
`
` 10 recites a wrist-worn device with an optical sensor, and
`
` 11 central to this is the calculation of heart rate variability
`
` 12 from the optical sensor data, from the PPG data. And this
`
` 13 is, again, I think for lots of things that, if memory --
`
` 14 called cardiac maladies. Actually, the precise term here
`
` 15 that's used the heart maladies, and they list a few, of
`
` 16 which atrial fibrillation is one of them.
`
` 17 Q. If we go to RDX-3.60, what does claim 16 add to
`
` 18 claim 12?
`
` 19 A. So claim 16 adds a smart watch or wristlet
`
` 20 according to claim 12, wherein indicating to the user
`
` 21 further comprises instructing the user to record an ECG
`
` 22 using the ECG sensor.
`
` 23 Q. If we go to RDX-3.61, does AMON disclose this
`
` 24 additional limitation of claim 16?
`
` 25 A. Yes, in my view it does. It mentions
`
`
`
`
`

`Heritage Reporting Corporation

`
`16
`
`
`
`
`
` 1127
`
`
` 1 specifically that when a parameter is out of range, the user
`
` 2 is informed to take additional measurements where one of
`
` 3 those measurements can be an ECG. And, moreover, the
`
` 4 patient is informed as to their own status and that of the
`
` 5 device.
`
` 6 Q. If we go to RDX-3.62, do you understand whether
`
` 7 AliveCor is disputing that AMON discloses the additional
`
` 8 limitation of claim 18?
`
` 9 A. It is my understanding that they are not.
`
` 10 Q. And in your opinion does AMON disclose the
`
` 11 additional limitation of claim 18?
`
` 12 A. Yes, it does.
`
` 13 Q. What does claim 19 add to claim 18?
`
` 14 A. So claim 19 adds, wherein the heart rate
`
` 15 parameter is a heart rate variability value wherein the
`
` 16 heart rate variability value is derived from the PPG signal.
`
` 17 Q. If we go to RDX-3.63, does AMON -- does the AMON
`
` 18 reference disclose the additional limitation of claim 19 in
`
` 19 your opinion?
`
` 20 A. Yes, it does. Again, it explicitly describes
`
` 21 calculating R-R distances, and heart rate variability being
`
` 22 calculated from R-R distances was well described at the
`
` 23 time. Workers and individuals in this area thought about
`
` 24 these things, not quite synonymously, but certainly one was
`
` 25 a knee-jerk reaction for the other concept.

`
`
` 1 Q. In May of 2013 would it have been obvious to
`
` 2 modify the AMON reference to use PPG data to derive HRV?
`
` 3 A. In my view, yes.
`
` 4 Q. If we go to RDX-3.64, to the extent AMON doesn't
`
` 5 disclose this, does Almen disclose calculating HRV from the
`
` 6 PPG signal?
`
` 7 A. So, as we've already discussed, a purpose of the
`
` 8 Almen, A-L-M-E-N reference, is to calculate HRV from optical
`
` 9 sensors, so yes.
`
` 10 Q. RDX-3.65, what does claim 20 require
`
` 11 additionally?
`
` 12 A. Claim 20 requires the smart watch according to
`
` 13 claim 18, wherein the heart rate parameter is a heart rate,
`
` 14 wherein the heart rate is derived from the PPG signal.
`
` 15 Q. If we go to RDX-3.66, does the AMON reference
`
` 16 disclose this additional limitation of claim 20?
`
` 17 A. In my view it does. It specifically mentions an
`
` 18 SpO2 sensor again, which is based or built off of PPG
`
` 19 sensors. Indeed, I have never seen an SpO2 sensor that did
`
` 20 not entail PPG technology. And in the middle figure it
`
` 21 specifically states that you can, from the SpO2, that there
`
` 22 are calculations of pulse.
`
` 23 Q. If we go to RDX-3.67, does AMON alone and/or in
`
` 24 combination disclose all the limitations of claims 13, 16,
`
` 25 18, 19, and 20?
