` JUDGE GIANNETTI: Please be seated.
` Good morning, everyone. We are here for a final
`hearing this morning in Samsung Electronics Co. versus UUSI,
`LLC, doing business as Nartron. This is case IPR2016-00908.
` Welcome, everyone. And let me introduce the
`panel. I am Judge Giannetti. I will be presiding. And we
`have two judges who will be participating remotely. On the
`screen to my left is Judge Jivani, and participating via
`audio is Judge DeFranco.
` Let's start by getting appearances of counsel.
` Petitioner, who is appearing today for you?
` MR. MODI: Good morning, your Honors. Naveen Modi
`from Paul Hastings on behalf of petitioner. With me I have
`my colleagues Joe Palys and Chetan Bansal. Mr. Bansal will
`be presenting the argument for Samsung today.
` JUDGE GIANNETTI: Mister -- is it Bansal?
` MR. MODI: Yes, sir.
` JUDGE GIANNETTI: Okay. And he's admitted pro hac
`or is he --
` MR. MODI: He's -- he is admitted, your Honor.
` JUDGE GIANNETTI: He's admitted.

` JUDGE GIANNETTI: Would you spell his name. It's
`B-o-n-s-a-l?
` MR. MODI: B-a-n-s-a-l.
` JUDGE GIANNETTI: Okay. B-a-n-s-a-l. All right.
`Mr. Bansal.
` All right. And for patent owner who is appearing
`today?
` MS. SUMMERS: Good morning, your Honors. My name
`is Teresa Summers. I'm with DGKIP Law and I represent the
`patent owner UUSI. And with me at counsel table is Cecil
`Key.
` JUDGE GIANNETTI: Okay. Ms. Summers. I'm going
`to switch chairs, if you'll just bear with me for a second.
`All right. More comfortable.
` All right. So, let me go over some details before
`we get started. First of all, each side will have 45 minutes
`to present its argument. The petitioner may reserve time for
`rebuttal. Petitioner will start the argument. And the
`rebuttal time, I think you can --
` Petitioner, you can reserve that either at the

`beginning of the argument or you can reserve the balance of
`the time at the end of the argument. I'll leave that up to
`you.
` Let me say a word about demonstratives. Both
`sides have submitted demonstratives, and I want to make it
`clear that demonstratives are an aid to argument. They are
`not part of the record of this proceeding. The official
`record will be the transcript that the court reporter will
`prepare and will be filed as part of the record in the
`proceeding.
` The transcript -- so, if you want something in the
`record, make sure that it is on the transcript.
` You are not authorized to file the demonstratives.
`The panel will review them and, if necessary, at the
`proceeding will authorize you to file the demonstratives.
` One other matter with regard to demonstratives.
`Since we have two judges appearing remotely, participating
`remotely in our proceeding, when you do refer to your
`demonstratives, please call out the slide number. They have
`the demonstratives that you have provided us. They will be
`able to follow along, but you have to call out the slide
`number when you refer to your demonstratives. And I will try

`important for the two judges who are appearing remotely.
` Any questions, petitioner? Any questions,
`Mister --
` MR. BANSAL: No, your Honor.
` JUDGE GIANNETTI: Mr. Bansal, any questions?
` MR. BANSAL: No, your Honor.
` JUDGE GIANNETTI: All right. Any questions from
`patent owner?
` MS. SUMMERS: No, your Honor. Thank you.
` JUDGE GIANNETTI: All right. Let me just set the
`timer here for 45 minutes.
` Okay. Mr. Bansal, do you want to reserve time now
`or do you want to do that at the end?
` MR. BANSAL: I may use the remainder of my time
`for rebuttal.
` JUDGE GIANNETTI: Okay. Fine. So, we'll just
`start with 45 minutes, and whenever you stop, whatever time
`you have left will be your rebuttal.
` Okay. You can proceed when you're ready.
` MR. BANSAL: Your Honor, we have a hard copy of
`our demonstratives. Would you like a copy?

` You may proceed when you're ready, Mr. Bansal.
` MR. BANSAL: May it please the board. My name is
`Chetan Bansal, and I represent Petitioner Samsung Electronics
`in this proceeding.
` Based on the petition and the supporting evidence,
`the board instituted trial. The record now includes even
`more evidence that further supports the board's institution
`decision. The board should issue a final decision canceling
`all claims at issue. Let me explain why.
` Turning to slide number 2, this slide reproduces
`the two instituted grounds in this proceeding.
` JUDGE GIANNETTI: You're not going to project the
`slides; is that right? I don't see --
` MR. PALYS: Your Honor, our understanding, there
`was a technical glitch on the patent office's side and that
`it's unavailable. So, we've been instructed to proceed in
`this manner.
` JUDGE GIANNETTI: I see. All right. Well, we'll

`
`just -- we'll just use the copies that you've given us. And,
`so, now all of the -- all of the panel is equally without a
`display. We'll just follow along. Just give me a second
`while I get your demonstratives.
` All right. You can proceed.
` MR. BANSAL: Your Honor, as I was saying, on slide
`number 2, our -- the two instituted grounds, the first ground
`is a three-reference combination between Ingraham I,
`Caldwell, and Gerpheide, and the second ground is a
`combination between four references, Ingraham I, Caldwell,
`Gerpheide, and Wheeler. Each of these four references relate
`to capacity of touch systems where a user's touch is sensed
`based on a change in capacitance.
` Turning to slide --
` JUDGE GIANNETTI: Let me ask you something,
`counsel. I thought it was --
` JUDGE JIVANI: Let me interrupt you for a second.
` JUDGE GIANNETTI: Go ahead, judge.
` JUDGE JIVANI: So, counsel, you just said each
`reference is directed to touch capacitance. I understand
`from the briefing that there's an issue as to whether
`Caldwell increases touch sensitivity or decreases it. Would

`19
`20
`21
`22
`
`you please speak to why one of ordinary skill in the art
`would look to Caldwell.
` MR. BANSAL: Sure, your Honor. Your Honor,
`Caldwell, as explained in our papers, also describes the
`capacitive proximity system where, when the user touches the
`touch terminal, the capacitance changes. And the change in
`capacitance is what is sensed by the circuit to determine
`whether a touch terminal has been touched.
` JUDGE JIVANI: But Caldwell's approach,
`nevertheless, is to bury the touch terminals on the opposite
`side of the substrate, is it not?
` MR. BANSAL: Your Honor, I -- you know, it is
`ultimately a capacitive touch system. And then when you look
`at the claims, the claims do not specify any sort of
`requirement whether the touch terminals are on one side of
`the substrate or the other.
` JUDGE JIVANI: All right. And then, counsel, you
`also addressed Gerpheide for a moment. As you know, you
`mentioned our decision on institution. In that decision, we
`noted that there's conflicting expert testimony in the record
`at that time on whether one of ordinary skill would look to
`Gerpheide. I believe you just told us a moment ago that

`22
`
`there's now much more evidence. What is that additional
`evidence?
` MR. BANSAL: Your -- your Honor, you know, we have
`our arguments on rebuttal. Plus, also, you know, I think
`there is evidence in the sense that there are arguments that
`the patent owner has made. But when you look at the totality
`of the evidence, you know, Gerpheide is related to the other
`two references. And when you look at the combinations
`together, each of those combinations disclose every
`limitation that's in the claims.
` JUDGE GIANNETTI: Counsel -- I'm sorry.
` JUDGE JIVANI: Counsel -- Judge Giannetti, please
`proceed.
` JUDGE GIANNETTI: Yes. Just -- your starting
`point here is Ingraham -- Ingraham I; right?
` MR. BANSAL: Yes, your Honor.
` JUDGE GIANNETTI: -- which is a Nartron patent.
`Patent owner owns that patent or at least that was their
`patent at one time.
` MR. BANSAL: Yes, your Honor.
` JUDGE GIANNETTI: And it's discussed -- it's
`discussed in the -- in the specification of the '183 patent,

`22
`
`isn't it?
` MR. BANSAL: Yes, your Honor, the specification of
`the '183 patent --
` JUDGE GIANNETTI: So, it was before -- it was
`before the patent office during the examination of the
`patent; correct?
` MR. BANSAL: Yes, your Honor.
` JUDGE GIANNETTI: And isn't that also true of
`Gerpheide, that it was before the patent office in connection
`with one of the reexaminations?
` MR. BANSAL: Yes, your Honor.
` JUDGE GIANNETTI: So, why did you pick art that
`the PTO had already considered? What was your rationale for
`picking Ingraham, which was also discussed and distinguished
`in the specification?
` MR. BANSAL: Your Honor, quite honestly, the
`rationale is that these references are most pertinent to the
`claims at issue. You know, the claims at issue claim what,
`for the most part, is present in the Ingraham I reference.
`There are certain features that are then known or, you know,
`are established as being known by the Caldwell and the
`Gerpheide references. That's why those three reference

`
`foundations were picked, at least for the impact --
` JUDGE GIANNETTI: Well, the examiner didn't think
`so or the examiner wouldn't have allowed the claims.
` MR. BANSAL: Your Honor, the examiner was not
`presented with the exact combination that is presented in the
`petition. Moreover, the examiner did not have the benefit of
`Dr. Subramanian's testimony, which explains how these
`references in combination disclose every element of the
`claims.
` JUDGE GIANNETTI: One of the points that -- that
`patent owner makes is that Ingraham I talks about eliminating
`oscillators, does not show an oscillator. Do you agree that
`it does not show an oscillator?
` MR. BANSAL: Your Honor, as explained in the
`papers, Ingraham I discloses an oscillating signal. So, if I
`may turn to one of my slides, it may help. Can I please turn
`to slide number 6, your Honor.
` JUDGE GIANNETTI: Okay. Got it.
` MR. BANSAL: On the left-hand side of this
`slide --
` JUDGE GIANNETTI: Yes.
` MR. BANSAL: -- is a portion of a figure from

`
`Ingraham I.
` JUDGE GIANNETTI: Right.
` MR. BANSAL: As explained in the papers, there's a
`115-volt AC signal, 115-volt oscillating signal, that is
`provided in the circuit.
` JUDGE GIANNETTI: Well, how do you know that's an
`oscillator, though? That looks to me like a -- a socket, a
`wall socket, and that signal would be provided by a generator
`someplace off in a power terminal --
` MR. BANSAL: Exactly, your Honor.
` JUDGE GIANNETTI: -- not an oscillator.
` MR. BANSAL: That's why what we explained and what
`Dr. Subramanian explained was an oscillator would be
`necessary for generating this 115-volt AC signal.
` JUDGE GIANNETTI: Why is that?
` MR. BANSAL: Your Honor, because that's what
`oscillators do.
` JUDGE GIANNETTI: But generators generate 115-volt
`AC signals, too, without oscillators.
` MR. BANSAL: Your Honor, as explained by
`Dr. Subramanian, the generators are going to have an
`oscillator. Regardless of that, your Honor, if you look to

`
`slide number 7, we rely on Caldwell --
` JUDGE GIANNETTI: As an old -- old line electrical
`engineer, I have to say I disagree with that. I think you
`can provide an 115-volt AC signal without an oscillator with
`a generator. So, I don't accept that testimony. Is that --
`is that what you point to as being the presence of an
`oscillator in that Ingraham I?
` MR. BANSAL: Your Honor, what we point to is that
`there's 115-volt AC signal. An oscillator would -- you know,
`would be present, but to the extent it is not present or to
`the extent it's not explicitly disclosed in Ingraham I,
`Caldwell discloses an oscillator.
` As -- if you turn to slide number 7, we -- we rely
`on the Caldwell reference for the teaching of an oscillator.
`As you see on slide 7, figure number 12, of Caldwell, there's
`an oscillator 30 that provides an oscillating signal to the
`array of touch pads 42.
` JUDGE GIANNETTI: Okay. I interrupted Judge
`Jivani, so I will yield the floor to him.
` JUDGE JIVANI: I appreciate that.
` So, counsel, I still want to return to your
`motivation to combine. I understand that you're seeking

`
`combining the oscillator from Caldwell, but why would one
`look to Caldwell?
` MR. BANSAL: Your Honor, one would look to
`Caldwell because, well, first of all, Caldwell is also in the
`same field as Ingraham I, which is the positive touch
`responsive systems. But the other reason, as we have
`explained in the papers, is like Judge Giannetti mentioned,
`Ingraham I will require the wall power supply for its
`oscillating signal. But Caldwell discloses a local
`oscillator.
` Now, if you take the local oscillator and you
`combine that with Ingraham I, now that system, the combined
`system, is capable of operating in a portable manner. That
`is now the system can be applied to a system which may not
`have the benefit of the wall power supply.
` JUDGE JIVANI: So, to make it portable.
` MR. BANSAL: Yes, to be portable.
` JUDGE JIVANI: And according to patent owner's
`counsel, at least in the papers, that portable system would
`shock the user; is that correct?
` MR. BANSAL: No, your Honor. Let me -- well, yes,
`in the sense -- they make this argument but the argument is

`
`incorrect. Let me address that, your Honor.
` JUDGE JIVANI: Please.
` MR. BANSAL: So, if I may turn to slide number 30,
`your Honor.
` JUDGE JIVANI: Okay.
` MR. BANSAL: On slide number 30, at the bottom is
`an excerpt from Ingraham I. It's the control circuit from
`Ingraham I. And as you can see, your Honor, on the left-hand
`side of that circuit is the input touch portion 13, which is
`where the user would touch.
` And then before that, there are two resistors, 44
`and 46. These are extremely high value resistances. And as
`noted by Ingraham II, which is incorporated by reference in
`Ingraham I, the function of those two resistors is to make
`sure the user is not shocked. Because what those two
`resistors do is they prevent any harmful electric current
`from being provided to the user when the user touches the
`touch portion.
` JUDGE GIANNETTI: Let me just note for the record
`that this slide 30 is the diagram that we're referring to as
`figure 3 from Ingraham I. Is that right, counsel?
` MR. BANSAL: Yes. Yes, your Honor, it's an

`
`excerpt from figure 3 of Ingraham I.
` JUDGE GIANNETTI: Okay.
` JUDGE JIVANI: And, so, counsel, are these
`resistors also described in Ingraham I or are you turning to
`the description in Ingraham II?
` MR. BANSAL: Your Honor, these resistors are
`present in Ingraham I as shown in figure 3, but Ingraham I
`does not provide every detail of its control circuit, and it
`says that the details of its control circuit are present in
`Ingraham II. So, it actually incorporates that portion of
`Ingraham II by reference.
` And Ingraham II, which has the exact same
`resistors, the exact same circuit, explains what the function
`of those two resistors is.
` JUDGE JIVANI: Okay.
` MR. BANSAL: Your Honor, so turning back to slide
`number 3, your Honor is very well aware of the technology at
`issue, but we thought it may help to provide a very quick
`overview of one of the embodiments. And the --
` JUDGE JIVANI: Actually, counsel, let me pause
`you. We're familiar with the embodiments. And in the
`interest of time, let me ask you to move forward from the

`
`oscillator we just discussed to your next limitation.
` MR. BANSAL: Sure, your Honor.
` JUDGE JIVANI: Thank you.
` MR. BANSAL: Your Honor, so, turning to slide
`number 9, slide number 9 has the feature of a micro-
`controller using the periodic output signal from the
`oscillator, the microcontroller selectively providing signal
`output frequencies to a plurality of small-sized input touch
`terminals of a keypad.
` So, your Honor, keeping the frequencies limitation
`aside for now, what Ingraham I discloses is a plurality of
`input touch portions. Each of those touch portions receive
`the oscillating signal, which, if you look at the figure on
`slide number 9, the signal in green is the oscillating signal
`and that is being provided to each of those input touch
`portions.
` What's missing, though, is that the signal, the
`oscillating signal, is directly provided to the input touch
`portions as opposed to being provided via a microcontroller,
`as required by the claim.
` So, now, if you turn to slide number 10, slide
`number 10 describes the Caldwell reference where there's an
`

`
`oscillator, 30, that provides the oscillating signal to the
`array of touch pads, 42. But here, now, the oscillating
`signal is selectively provided via the microprocessor and the
`demultiplexer to the area of touch pads.
` So, what Caldwell discloses is a scanning
`technique. That is, you pick a row; you provide the
`oscillating signal; then you go to the next row; and then you
`provide the oscillating signal to the next row.
` JUDGE GIANNETTI: That's a predetermined sequence;
`is that correct, counsel?
` MR. BANSAL: Yes, your Honor, that's a pre -- it's
`a predetermined sequence.
` JUDGE GIANNETTI: And isn't that a distinction
`between Caldwell and the patent, the '183 patent?
` MR. BANSAL: No, your Honor, this is not a
`distinction between the claims of the '183 patent and
`Caldwell.
` JUDGE GIANNETTI: I thought that was something
`that was being contested.
` MR. BANSAL: Your Honor, as we've explained, the
`claims simply require that the oscillating signal must be
`selectively provided to each row of the input touch

`terminals, which is something that Caldwell discloses and,
`therefore, the combination of Ingraham I and Caldwell
`discloses.
` JUDGE GIANNETTI: Well, what is selective if it's
`doing it in a particular sequence?
` MR. BANSAL: That is you select one row and you
`provide the signal to that row; you select the next row and
`then you provide the signal to that row.
` JUDGE GIANNETTI: That's your position on that.
` MR. BANSAL: Yes, your Honor.
` Turning to slide number 11 -- Judge Jivani, did
`you have a question? I thought I heard something.
` JUDGE JIVANI: Yes. Judge Giannetti -- Giannetti
`covered it.
` Thank you, Judge Giannetti.
` I do have a follow-on question, which is, counsel,
`are you seeking a specific construction of the selectively
`providing signal output frequencies limitation?
` MR. BANSAL: No, your Honor. We have explained
`our position in our papers.
` JUDGE JIVANI: Thank you.
` MR. BANSAL: Your Honor, turning to slide 11, now,

`
`you know, I described Ingraham I. I described Caldwell.
`Now, when you put the teachings of those two references
`together, what you get is a system where the microcontroller
`not only provides an oscillating signal to the input touch
`terminals but it actually selects each row and then provides
`a signal selectively to each of the rows.
` Dr. Subramanian created a demonstrative, which is
`demonstrative C on slide number 11. This demonstrative
`provides one example of what the combined system would look
`like. And as you can see from the demonstrative, the
`oscillator signal is provided to the microcontroller, and the
`microcontroller selects which row -- or selects a row of
`input touch portions to which the oscillator signal is
`provided.
` Turning to slide number 12, your Honor, as
`explained in our papers, there would have been several
`advantages to combining the teachings of Ingraham I and
`Caldwell in this manner. For one --
` JUDGE JIVANI: Before you move off of -- before
`you move into the advantages, I want to understand the
`interplay between claims 40 and 45 since your papers raise
`claim 45. You just said that your combination would take the

`
`signal frequency, the signal from the oscillator, and
`selectively provide it to each row. And I believe what
`you're saying is that the same signal and same frequency
`would be sent to each row. Does that not collapse 40 and 45
`to the same scope?
` MR. BANSAL: No, your Honor. 45 is covered within
`the scope of 40. So, 40 can do what's in 45 or it can do
`something different. So --
` JUDGE JIVANI: I understand how dependency works,
`but explain to me the difference between the claims if, under
`your theory, what's required in claim 40 is only selecting
`the same frequency and sending it to each row.
` MR. BANSAL: So, your Honor, what claim 40
`requires and what our analysis shows is that a frequency is
`selectively provided to each row. That is, the system
`selects each row and then provides a frequency to it. When
`you come to claim 45, we explained that the combined system
`provides this in frequency and that's why the combined system
`meets claim 45.
` JUDGE JIVANI: Okay.
` MR. BANSAL: So, your Honor, coming back to slide
`number 12, slide number 12 explains the different advantages

`
`that would be gained by combining the teachings of Ingraham I
`and Caldwell in the manner that has been described. For one,
`you can decrease the number of I/O pins in the
`microcontroller; two, you can reduce the number of wires
`and which increases signal integrity.
` Turning to slide number 13, your Honor, this is
`the next aspect that I wanted to explain, which is the
`frequencies aspect of claim 40. Gerpheide discloses a system
`in which the microcontroller varies the oscillator frequency
`and provides different frequencies to the input touch
`terminals or, you know, to the touch pad.
` JUDGE JIVANI: Wait, counsel. It provides
`different frequencies to each terminal?
` MR. BANSAL: No, your Honor, that's not what it
`says. What I said was the microcontroller has -- you know,
`is -- it's changing the frequency of the oscillator with time
`because, for instance, there may be interference at a certain
`frequency and, so, the microcontroller is able to change the
`oscillator frequency and then provide the changed frequency
`to the touch terminals.
` JUDGE JIVANI: But each terminal still gets the
`same frequency in Gerpheide, correct, such that in your

`
`combination, every row would still receive the same
`frequency?
` MR. BANSAL: Your Honor, that's one implementation
`of the combination that we have represented.
` JUDGE JIVANI: Okay. And at the outset of the
`argument, I asked you to please tell me what evidence you
`have that one of ordinary skill would look to Gerpheide.
`Counsel, I don't believe I received an answer, so, I'm going
`to give you another opportunity to please tell me. What
`evidence do you have in the record that one would look to
`Gerpheide?
` MR. BANSAL: Sure, your Honor. So, as explained
`in our papers, your Honor, Gerpheide notes that there was a
`known problem with interference in capacity of touch systems,
`that there is interference that exists at different
`frequencies. One way to negate that interference is for the
`microcontroller to check the interference at different
`frequencies and then change the frequencies based on, I
`guess, the frequency which has the least amount of
`interference.
` And given that -- that knowledge of one of
`ordinary skill, as evidenced by Gerpheide, one of ordinary

`
`skill in the art would have looked to Gerpheide, given this
`known problem and the solution that Gerpheide provides.
` JUDGE GIANNETTI: I guess the problem that I have
`with that is that when it changes the frequency, it changes
`it until there's another episode of interference. So, it's
`delivering the same frequency. It's not selectively, I
`guess, as I might -- as one might interpret that. It's not
`really being selective; it's just it's selecting a new
`frequency and then providing that frequency to all of the --
`all of the elements.
` MR. BANSAL: Your Honor, the selective aspect is
`the selecting of a row and then -- right? So, let's say, if
`you have 20 rows, at any given instance, only one row will
`receive the oscillating signal.
` JUDGE GIANNETTI: But all the rows will receive
`the same oscillating signal, the same frequency, until the
`frequency is changed as a result of the different
`interference events; is that correct?
` MR. BANSAL: In one implementation, yes, your
`Honor. That is, you would -- you may not change the
`frequency until there is interference at that frequency or,
`you know, for some other reason. But the point is that you

`
`select a row and you provide an oscillating signal to it; you
`select another row, and then you provide the oscillating
`signal to it.
` JUDGE GIANNETTI: The same oscillating signal.
`The same frequency.
` MR. BANSAL: The same frequency unless the
`frequency got changed in between. Right? So, if you have 20
`rows, you don't have to go through all the 20 rows. The
`microcontroller will be assessing interference. And if it
`senses interference, at some point the frequency may get
`changed. So, two rows may actually end up getting different
`frequencies. But, your Honor, I think --
` JUDGE JIVANI: Where is that in your argument?
`Where is that in your papers, what you just described?
` MR. BANSAL: Your Honor, I believe that's
`consistent with what we have in the papers, which is the
`microcontroller can change the frequency.
` Now, I was just, you know, responding to Judge
`Giannetti's question about is there a change between
`frequencies, but -- and, you know, one implement or one
`example or one consequence of the combined system would be
`what I just described.

`
` But, I think, your Honor, I think we should focus
`on the claims. And if you look at what the claims require,
`the claims nowhere require that the frequency between each
`row be different. In fact, if you look at claim 45, which
`depends off of claim 40, it specifies that the frequency for
`each row can have the same frequency value.
` So, your Honor, moving on to slide number 14, I
`already described the advantage that Gerpheide provides,
`which is it provides a technique using which you can negate
`interference by the microcontroller proactively sensing
`interference on different frequencies and changing the
`frequency.
` And for this reason, one of ordinary skill in the
`art would have been motivated to combine the teachings of
`Ingraham I, Caldwell, and Gerpheide, such that the combined
`system now changes frequency based on an interference
`measurement.
` JUDGE GIANNETTI: Is Gerpheide really a k
