`JUDGE LEE: Welcome to the Board. We have Judge John Kenny
`
`and Judge Jessica Kaiser. They’re appearing remotely; one from Denver,
`the other one from Seattle. And let me remind counsel, they can only see
`you if you’re standing at the podium. This is the oral hearing for IPR2017-
`01881 and both sides have 45 minutes of argument time. Let’s begin with
`introduction of counsel, starting with Petitioner followed by Patent Owner.
`
`MR. OAKS: Good afternoon, Your Honors. My name is Brian Oaks.
`I’m lead counsel for the Petitioner, Cisco Systems and Oclaro, Inc., and with
`me is Mr. Darren Donnelly, who is also counsel for the Petitioners.
`
`JUDGE LEE: Thank you.
`
`MR. HELGE: Good afternoon, Your Honor. I am Wayne Helge, here
`appearing for the Patent Owner, Oyster Optics, LLC. With me is Mr. Aldo
`Noto, N-O-T-O, also an attorney representing Oyster Optics.
`
`JUDGE LEE: Thank you. And Mr. Oaks, you could reserve some
`time for rebuttal. If you let me know and I’ll set it.
`
`MR. OAKS: Thank you, Your Honor. I’d like to target for reserving
`ten minutes of my time.
`
`JUDGE LEE: How much?
`
`MR. OAKS: Ten minutes.
`
`JUDGE LEE: Ten? Thank you. You may begin anytime you’re
`ready.
`
`MR. OAKS: Thank you. Well, good afternoon, Yours Honors, may
`it please the Board. I’ll jump right into it. So I’m looking at Slide 3. I

`
`won’t go into this in detail now, but this is just sort of a road map of what
`I’d like to talk to you about this afternoon. These are highlighting the issues
`that are really in contention in this case.
`
`So going right into it, I’d like to start with Claim 14. So Claim --
`there’s only one independent claim at issue in this matter and that’s
`Independent Claim 14, and really, other than Dependent Claim 19, it’s the
`only claim that’s really in contention. The other claims are not subject to
`additional briefing in this case.
`
`So Claim 14 recites a transceiver card and it requires that there be a
`certain number of elements collectively together on this transceiver card.
`There’s five elements. There’s a transmitter, and that transmitter has a laser,
`a modulator, and a controller. Secondly, there is a fiber output that is
`connected to that transmitter. There is a receiver, and then there is a fiber
`input connected to that receiver.
`
`So those four, the first four items, are all items that are admitted in the
`background of the ‘898 patent to be prior art. The ‘898 patent background
`says that their prior art exists that are transceiver cards that have these
`elements. Now, the additional element that was supposedly the, I guess, the
`alleged invention of the ‘898 patent is the inclusion along with those
`elements of an energy level detector also on the card.
`
`So in our combinations, although the ‘898 patent admits that the first
`four are prior art, we have also provided the reference, Ade, which discloses
`all four of those elements together on the same card. In fact, on the same
`chip. And then we’ve combined that with two different references, Corke
`and Roberts, and both of those references are used to show an energy level
`
`
`

`
`detector that is integrated with the receiver so that, in combination, there is a
`transceiver card that has all five elements.
`
`So this -- going to the Corke/Ade combination in particular, this is the
`-- some of the petition’s explanation of that combination and, at a high level,
`this is the summary after the discussion of that. What the petition says is,
`“The proposed” -- and I’m sorry, I’m on Slide 6. It says, “The proposed
`combination therefore includes a single card with Corke’s optical power
`detectors and Ade’s receiver, transmitter, and modulator with control
`circuitry.” And then also in the petition it goes on, supported by the
`testimony of Dr. Blumenthal, to talk about the predictability of combining
`these elements together on a card.
`Moving on to Slide 7, these are a couple of excerpts from the institution
`decision. The first one to the top right is the institution decision basically
`recognizing that same combination that I just mentioned, the proposed
`combination using Corke’s optical power detectors, combined with Ade’s
`receiver, transmitter, and modulator with control circuitry, all on a single
`card.
`As the panel noted in the institution decision, while neither Ade nor
`
`Corke specifically or explicitly discloses how to arrange a transceiver on --
`I’m sorry, an energy level detector on a card, the Board, preliminarily found,
`at least, that Petitioner had provided evidence that the combination of those
`references, along with the testimony of Dr. Blumenthal, did teach that
`combination.
`
`Now, the Board also noted that at that stage, at least, the Patent Owner
`had disagreed with that combination and whether it was obvious, but said
`
`
`
`
` 5
`
`

`

`24
`25
`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`that the Patent Owner hadn’t provided evidence to support those arguments.
`Well, the Patent Owner still hasn’t provided that evidence. So the Patent
`Owner did, in this case, provide an expert declaration from Dr. Goossen, but
`what Dr. Goossen does in his testimony on the combination is related to
`tearing down this strawman combination that Patent Owner has built. That
`isn’t the combination that’s proposed.
`So Dr. Goossen doesn’t contradict Dr. Blumenthal’s testimony that it would
`be obvious to put an energy level detector on a transceiver card. Instead, he
`goes into a lot of detail tearing down what he says is the combination that
`was proposed. So I’d like to go into that next and exactly what the
`combination is. So I’m
`moving on to Slide No. 11. So backing -- well, first of all, backing up to
`Slide 10 to the road map, there’s basically two assumptions that Patent
`Owner is making with the combination that aren’t correct. The first is that
`the combination requires the inclusion of Corke’s protection switching and
`the second is that, along with the protection switching, that it even requires a
`particular embodiment of Corke that uses a bidirectional fiber, and neither of
`those are true.
`
`So with respect to the first issue, whether protection switching is
`included in the combination, the Patent Owner argues that this is the case, or
`at least that that’s their interpretation of our combination. However, in
`response to them saying this, you know, we disagree that that’s the
`combination, we'd point out that Corke expressly teaches that one does not
`have to use the protection switching in all of its embodiments.
`And so here, I’m on Slide 11, there’s an excerpt from Corke, column 11,
`
`
`
`
` 6
`
`

`

`23
`24
`25
`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`starting at line 2, and it says, “The same monitoring system,” so this is
`talking about the energy level detector in Corke, “can also be employed
`simply to provide performance information to an operator, or computerized
`management system, or to automatically control an alarm to trigger a
`diagnostic sequence, thus the invention. In addition to its importance to
`actuating the switching between routes,” that's the protection switching, “has
`other important applications as well.”
`
`So Corke explicitly states that it doesn’t have to have -- that you don’t
`have to have protection switching and all of its embodiments. It’s clearly
`saying that there is validity and importance in just the monitoring and that’s
`the monitoring that we’re using in the combination.
`
`JUDGE LEE: Can I interrupt you?
`
`MR. OAKS: Uh-huh.
`
`JUDGE LEE: What is the theory in the petition when you made the
`combination? Was it to continue with the protection switching or was it
`simply to do as you just quoted, to collect data?
`
`MR. OAKS: So the theory as I put in the -- had in the excerpt from
`the petition is that you have all the teachings in Ade of a transceiver card,
`and it has a chip and we’ll get to how that discloses a card. You have a
`transceiver card with transmitter receiver, transmitter with a laser, and a
`receiver, and the optical input and output. It’s missing the energy level
`detector and Corke discloses that you have -- it’s quite common to have a
`receiver that has an associated monitor and energy level detector to check
`the received signal.
`
`And so the POSITA would understand that you don’t have to take
`
`
`
`

`24
`25
`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`every bit of Corke and Ade and combine them together. That’s improper
`legal analysis to say that everything that’s in those references has to be put
`together. And so what the petition suggests and says is that you take
`Corke’s energy level detector, which it teaches is associated with the
`receiver and you combine that with Ade’s teaching of having the receiver
`and the transmitter together on a card, on a chip, in fact.
`
`JUDGE LEE: So it isn’t limited to any particular subsequent purpose,
`whether it’s to a protection switch or to simply gather data?
`
`MR. OAKS: The only purpose is to monitor the signal. So you have
`the transmitter to transmit signals, the receiver to receive signals, and a
`detector to monitor the received signal.
`
`JUDGE LEE: So it didn’t matter for your combination whether it’s
`used simply to monitor or to actually carry out protection switching?
`
`MR. OAKS: That’s correct. The petition -- nowhere in our briefing
`do we point to the protection switching or the elements of the protection
`switching as being part of the combination or necessary to the combination.
`
`So, and with respect to whether Corke discloses what I said, that it
`only has to use monitoring, Dr. Goossen, the Patent Owner’s expert, did
`agree that -- well, that’s -- at least -- he, at least, agreed that’s what Corke
`states and Dr. Blumenthal testified that a POSITA would readily understand
`how you would combine the energy level detector that’s in Corke with Ade,
`and it’s quite simple.
`And
`I’ll talk about it in a minute, but it’s -- you just have -- all you have is a tap
`coming off of the received optical signal. You tap part of it with the
`photodetector and the rest of it goes to the receiver. That’s what’s disclosed
`
`

`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`in Corke and that’s exactly what it -- how it would be used in the
`combination.
`
`So because the entirety of Patent Owner’s arguments related to the
`combination assumed that protection switching must be included in the
`combination, and that’s a faulty assumption, they basically have no
`argument as to the actual combination, which is that it’s obvious to put an
`energy level detector associated with the receiver with the integrated
`transceiver components of Ade.
`
`JUDGE KENNY: Well, let me ask you. Why was it obvious to use
`the two fibers in this combination?
`
`MR. OAKS: Well, that -- I mean, so Ade discloses the two fibers and
`Ade actually says -- discloses you can have either. You could have a single
`input that’s for a bidirectional fiber or you can have two inputs: one for one
`unidirectional fiber that transmits and for a unidirectional fiber that receives.
`And so Ade, itself, talks about the interchangeability of these and what we
`pointed to in the combination was Ade’s use of -- the particular use of the
`two fiber inputs and that’s similar in Corke. Corke also talks about you
`could use unidirectional fibers or bidirectional fibers.
`
`JUDGE KENNY: Well, now Corke doesn’t disclose using
`unidirectional fibers with a transceiver, right?
`
`MR. OAKS: That’s correct. Well, it doesn’t disclose the -- well,
`what Corke shows is a close-up on the received side with a unidirectional
`fiber in Figure 2 and it doesn’t show the transmit side. But it -- I mean, to
`answer your question -- right, so --
`
`JUDGE KENNY: Okay. So I think Patent Owner has made an issue
`
`
`

`22
`23
`24
`25
`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`as to whether one skilled in the art would be motivated to use the dual fiber,
`particularly in light of a particular advantage from Corke, with respect to a
`bidirectional fiber. So kind of looking at this combination, can you tell me
`why one skilled in the art would choose separate fibers with a transceiver
`given that there appears to be an advantage, at least as Patent Owner
`contends, of bidirectional fibers?
`
`MR. OAKS: So let me turn to my next slide because I think that this
`addresses your question. I’m on Slide 14. So Corke doesn’t prefer
`unidirectional fibers to bidirectional fibers in its protection switching. It
`provides two different alternatives to protection switching, Figure 2 and
`Figure 4, and there’s others as well, but those are the two that we have
`pointed to, and both of them enable protection switching.
`
`So Figure 2 has complete protection switching using unidirectional
`fibers without having the decision that’s made about the received side, but
`used to determine what you’re doing on the transmit side. And so as --
`
`
`
`JUDGE KENNY: But, I mean, Figure 2 doesn’t have a
`transmit side.
`
`
`
`
`
`
`
`
`
`
`MR. OAKS: Well, so the transmit --
`
`JUDGE KENNY: And, in other words, it’s just -- sorry. In other
`words, it’s a unidirectional path shown in Figure 2, correct?
`
`MR. OAKS: That’s correct. And so what’s described and not shown
`is that there’s two signals coming in from the left side of Figure 2. They’re
`duplicate signals.
`
`JUDGE KENNY: Right.
`
`MR. OAKS: They always both exist. And what the receiver is doing
`
`
`
`

`22
`23
`24
`25
`
`JUDGE KENNY: All right.
`MR. OAKS: -- control --
`JUDGE KENNY: Okay.
`MR. OAKS: This allows for protection switching in the event of a
`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`is looking at the primary route with the monitor, as well as looking at both of
`them actually, but if it monitors the primary route, determines there’s a fault
`or problem with that signal, it switches over to the other signal. And that’s
`what Dr. Blumenthal said is -- was common. It was called one-plus-one
`protection. It was quite common.
`
`So the Patent Owner’s argument that somehow you have to control
`the transmission direction based on that decision is just wrong. That's -- this
`--
`
`
`
`
`fault.
`JUDGE KENNY: Sure, in one direction.
`
`MR. OAKS: Correct.
`
`JUDGE KENNY: In the direction from left to right on the Figure.
`
`But if -- in Corke, they also talk about the fact that you can use the
`information from the reception to affect your choice on the transmission path
`and that you could not do with the unidirectional fiber, correct?
`
`MR. OAKS: That’s correct, but you already have the two signals
`being transmitted, so you don’t need -- I mean, the thing -- let me move to
`Slide 16. This is shown in Figure 4. I mean, it’s not really an advantage.
`It’s something you have to do. Because you’re sharing a fiber, you know
`that if the received signal is messed up, there’s a problem with the fiber and
`therefore you need to also switch the transmit side. It’s just an issue inherent
`
`

`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`with using a bidirectional fiber.
`
`But if you had a different set of fibers being used to transmit in the
`other direction, as disclosed in Ade, and as Dr. Blumenthal said was quite
`common and we cited some references that showed that, then you wouldn’t
`be coupling the transmitted and the received decision. It would be
`independent decisions. So you can imagine a receiver like in Ade that’s
`transmitting a signal, it would be received at another node and that node
`would be making the same decision whether to switch paths, you know,
`based on the received signal. So you have full protection switching and it
`was actually the common mode of protection switching without using a
`bidirectional fiber. And in Ade -- and Corke --
`
`JUDGE KENNY: Well --
`
`MR. OAKS: Corke never says, and Dr. Goossen admitted that Corke
`doesn’t preference Figure 2 or Figure 4. It’s just providing -- here’s two
`examples using the two kind of transmission fibers that were used in the
`systems at that time.
`
`JUDGE KENNY: Well, I mean, it does show a bidirectional fiber for
`the transceiver, right?
`
`MR. OAKS: For --
`
`JUDGE KENNY: I mean, in other words, the embodiment that has
`the transceiver has a bidirectional fiber?
`
`MR. OAKS: Right, because in showing the bidirectional fiber, they
`need to show the transmitter that’s connected to that same fiber. It’s sort of
`necessary to showing how the Corke’s Figure 4 embodiment works.
`
`JUDGE KENNY: But, so Figure 4 didn't illustrate unidirectional

`
`fibers with transceivers, right?
`
`MR. OAKS: That’s correct.
`
`JUDGE KENNY: So why would -- we’re just trying to get back to
`what would motivate one of ordinary skill in the art and where is it set forth
`in the record to use unidirectional fibers with a transceiver embodiment?
`
`MR. OAKS: Ade teaches that. So Ade --
`
`JUDGE KENNY: Okay. But given what Corke has, why would one
`do it when you combine the two? Ade has both, right?
`
`MR. OAKS: So, to me, this is --
`
`JUDGE KENNY: Ade --
`
`MR. OAKS: I’m sorry. Go ahead.
`
`JUDGE KENNY: Ade has both. Ade has both -- has -- describes --
`its main embodiment is bidirectional, but it talks about an alternative that’s
`unidirectional, correct?
`
`MR. OAKS: Right. Well, it actually starts with the unidirectional
`and then it talks about an alternative that’s bidirectional. Figure 2 comes
`first as a unidirectional. Oh, I’m sorry. Are you talking about Corke or
`Ade?
`JUDGE KENNY: Ade --
`
`MR. OAKS: Oh.
`
`JUDGE KENNY: -- with the transceiver.
`
`MR. OAKS: Yeah. Yes.
`
`JUDGE KENNY: So you’re saying the first figure is unidirectional?
`
`MR. OAKS: I thought you were talking about Corke. Are you
`
`talking about Ade or?

`
`IPR 2017-01881
`Patents 8,913,898 B2
`
`JUDGE KENNY: Yeah, Ade. Even in Ade, it first discloses a
`
`bidirectional embodiment and then it talks about alternatively you could, you
`know, remove the coupler and make it unidirectional, right --
`
`MR. OAKS: Correct.
`
`JUDGE KENNY: -- in certain fibers.
`
`MR. OAKS: Right.
`
`JUDGE KENNY: Okay. So looking at this, why, when somebody
`combines this, we have -- you know, the one shown in Corke is bidirectional
`and then you have both in Ade. Why would one go with unidirectional
`fibers in the combination?
`
`MR. OAKS: Well, like I said, in the combination, it doesn’t require
`protection switching. So we’re taking the teachings from Corke that say you
`have a received signal. Be it on a unidirectional or bidirectional fiber, you
`want to monitor that signal to understand what is going on with it. That is
`the teaching that is part of the combination. That can be used with
`unidirectional fibers or bidirectional fibers as disclosed in Corke.
`
`So trying to -- your question is kind of assuming that there has to be a
`bodily incorporation where you’re taking every bit of Corke, including the
`protection switching, and combining it with Ade, and that is --
`
`JUDGE KENNY: No, I’m just asking --
`
`JUDGE KAISER: Mr. Oaks?
`
`MR. OAKS: Yes.
`
`JUDGE KAISER: I’m just going to say it sounds like really what
`your argument is, is that this argument about the separate fibers is attacking
`a different combination than what you are trying to make. So it sounds like

`
`really the combination that you’re trying to make is that you take everything
`from Ade and really what you’re putting into it is the monitoring feature of
`Corke and not really worried so much about what the fibers are in Corke
`because that’s not what you’re relying on Corke for. Is that a fair
`assessment?
`
`MR. OAKS: Right, yes.
`
`JUDGE KAISER: Okay. And so then the fact that Corke has
`bidirectional fibers and a transceiver embodiment, I -- it sounds like you
`would say isn’t really relevant to how you would use the monitoring
`function.
`
`MR. OAKS: That’s correct. So Figure -- Corke discloses in Figure 2
`and Figure 4 that the monitoring is happening the same way. The
`monitoring happens on the received side in both Figure 2 and Figure 4 and
`that’s the teaching of Corke that we’re saying. So the idea is that Ade
`discloses and in, like I said, the ‘898 patent background admits that there’s
`transceiver cards with all these components. And the question is whether
`there would be an energy level detector associated with those components.
` And what we have shown, as in Corke and in Roberts, yes, that it’s quite
`common to monitor a signal that’s received. And so you have
`photodetectors, energy level detectors that are associated with receivers to
`monitor the received signal, and that’s true in Corke on both Figure 2 and
`Figure 4.
`
`Moving on to Slide 17. I’m not going to belabor this because we’ve
`talked about it, but, I mean, this is just the evidence that Dr. Blumenthal
`entered in his declaration talking about it is -- well, it’s quite common to
`
`
`
`

`
`have unidirectional -- to have two-way communications using unidirectional
`fibers, as well as you could do it using bidirectional fibers. As Ade suggests,
`they’re highly interchangeable.
`
`I’m going to skip ahead to the next section on Slide 21. So this relates
`to the teaching of Ade about having a laser being on a transceiver card. So
`Ade discloses, and I -- shown here from the figure on Slide 21, that you have
`a transmitter, including a modulator, on the same chip as the receiver and it
`also discloses highlighted in blue to the left of that, and it's Figure 1 of Ade,
`that you have a continuous wave laser input into that chip.
`
`And so what Dr. Blumenthal testified about was that a POSITA would
`know, very much well know, that you would mount a chip on a card, on a
`printed circuit board. That’s how chips are used in the wild, so-to-speak,
`and that you would do this for -- to provide robustness, and to account for
`environmental conditions, and improve reliability.
`
`And he also testified that you would also -- the POSITA would know
`that you want to have that laser as close to the modulator as possible for a
`number of reasons to avoid errors. And so all of that, collectively, tells a
`POSITA, yes, that what Ade is telling you is you have this modulator on a
`chip with a laser input and that laser would be on the card with the chip on
`which the chip is mounted.
`
`That’s why I said the Patent Owner has provided expert testimony
`from Dr. Goossen. Dr. Goossen did not provide any testimony on this issue.
`So Dr. Blumenthal’s expert testimony remains unrebutted.
`
`JUDGE LEE: What would be the purpose of adding a channel
`monitor to Ade?

`
`MR. OAKS: To monitor the signal to determine if there’s a problem
`
`with the signal, like, as in Corke.
`
`JUDGE LEE: I know, but for what purpose would you want to do
`that?
`MR. OAKS: I mean, it’s quite common, as Dr. Blumenthal testified,
`
`that you want to know is there a problem with the signal that I’m receiving
`on the chip. You want to know if there’s an error.
`
`JUDGE LEE: But see, when your declarant says that’s typical, there
`are --
`MR. OAKS: Right. So --
`
`JUDGE LEE: -- benefits in monitoring it.
`
`MR. OAKS: Right. So you want to understand. You know, these
`
`telecommunication providers are being paid a lot of money to communicate
`data and so they want to understand, is this actually working. Am I
`receiving the signal that I expect to receive?
`
`JUDGE LEE: Okay. And then Corke is just an illustrative example
`where such monitors have been used?
`
`MR. OAKS: That’s correct. I'd also point out on this issue about the
`laser that, again, the admitted prior art, the background of the ‘898 patent
`specifically says that the transceiver card has a laser and an amplitude
`modulation circuit located on the card together. And this, the point of Slide
`24 is just the panel decided in the institution decision that Patent Owner
`hadn’t provided any evidence to contradict Dr. Blumenthal’s testimony and,
`as I said, they still have not.
`
`So returning back to the specifics about Corke’s energy level detector,

`
`first why the combination teaches an energy level detector being on a
`transceiver card and I’m on Slide 27. So as I -- we’ve talked about, at
`length, Corke discloses an energy level detector that’s located with a
`receiver. And, as Dr. Blumenthal testified, the POSITA would have been
`motivated to put that energy level detector proximate to the receiver, and I’ll
`talk about that in a second.
`
`But I also wanted to note, as we described in our briefing, that if you
`look at -- I’m on Slide 27 at Ade’s figure. Ade already has a photodetector
`on its card. Now, it’s being used for the receiver function, but similar photo
`detectors are used, as disclosed in Corke, to monitor. So just to show that
`it’s not crazy that we’re talking about putting a photodetector on a card with
`these elements.
`
`JUDGE
`LEE: It seems the parties have argued past each other, so let’s put aside
`your real argument, according to you --
`
`MR. OAKS: Uh-huh.
`
`JUDGE LEE: -- what do you think that really is? Let’s assume that if
`the argument actually is what they say it is, do you have a response or do
`you just say, “Oh, well that’s not our argument, so we’re not even
`responding to that. I don’t have an answer for that. If the Board decides that
`that’s what the argument is, then I'm," is it like that or do you say --
`
`MR. OAKS: Well, so if you want to include a combination that has
`all of what’s in Corke, you could use Figure 2. So in the bodily
`incorporation mode of the combination, you would put a transceiver chip
`into Figure 2. Now, Figure 2 doesn’t have a transmitter, but what Dr.
`Blumenthal testified about is that it’s quite common, and a POSITA would

`

`
`understand, that nodes have receivers and transmitters because there’s two-
`way communication.
`
`So you’re talking between two points and so it isn’t a one-way
`conversation. There’s data requested and transmitted back and forth, and so
`that is well known. And so it’s completely consistent with an understanding
`of the POSITA to put Ade’s chip directly into Corke’s Figure 2. And then,
`in that case, it would be receiving, just like the receiver is used in Corke’s
`Figure 2 and you would also have a transmitter.
`
`
`And
`Dr. Blumenthal testifies that in Ade’s chip those two, the transmitter and the
`receiver, at least in the two fiber embodiment where there’s unidirectional
`fibers, they’re completely de-coupled. They’re separate. And so there’s
`nothing inconsistent with using Ade and bodily incorporate it into Figure 2.
`
`JUDGE LEE: So even -- you’re saying even under what they say you
`argued, you still say there was motivation to combine?
`
`MR. OAKS: Yes. Yeah, and that’s why we pointed to Figure 4
`simply to say, look, this does recognize that there’s transceivers. There’s
`transmitters and receivers and yes, Corke doesn’t disclose the unidirectional
`embodiment where there’s transmission -- a transmitter within the Figure,
`but Dr. Blumenthal said and provided evidence that that’s quite common.
`
`JUDGE LEE: Okay. But the main argument --
`
`JUDGE KENNY: But the -- sorry.
`
`JUDGE LEE: Go ahead.
`
`JUDGE KENNY: I take it the position is basically that Figure 2 has a
`transmitter, but it doesn’t show it. Is that your argument?
`
`MR. OAKS: No.

`
`JUDGE KENNY: I mean, it has a transmitter in that circuitry that’s
`
`illustrated, but it doesn’t show it?
`
`MR. OAKS: No, that’s not the argument. What I was saying was if --
`Judge Lee asked if we were going to follow this line, if we have to have
`everything that’s in Corke, including the combination. What I’m saying is
`that you could place Ade’s circuit, you know, the Ade’s chip into Corke for
`use as Corke’s receiver. In that combination, you also then have Ade’s
`transmitter. So I’m not saying Corke shows the --
`
`JUDGE KENNY: So you’re going to replace --
`
`MR. OAKS: Well, that -- this is not what I -- this is --
`
`JUDGE KENNY: -- just the receiver?
`
`MR. OAKS: Right.
`
`JUDGE KENNY: Okay. Well, the basic point of -- they are raising
`the issue of whether you’ve actually shown how the combination would go
`together. You didn’t do an overall schematic in your -- in any of your paper
`showing how the whole thing goes together.
`
`So, I mean, their argument is basically that even if you make this
`replacement that you’re talking about, you would end up with bidirectional
`fibers out the ends of Corke. And so just -- maybe you can address that.
`Exactly how is it, and get to whatever level of detail you need to, you would
`combine, or you proposed combining Corke and Ade.
`
`MR. OAKS: Well, as I said, we proposed a higher level combination.
`We believe that’s appropriate under the law, that the law doesn’t require that
`we engineer together sort of a mash-up of these two references, that we take
`teachings from one and teachings from the other and explain why a POSITA
