`JUDGE PETTIGREW: Good afternoon,
`
`everyone.
`
`I'm Judge Pettigrew. With me in the
`hearing room is Judge Benoit. And Judge Quinn is
`joining us by video from our Dallas office.
`This is a hearing for IPR 2015- 00635,
`ARRIS Group v. C-Cation Technologies, challenging
`U.S. Patent Number 5,563,883. A second proceeding,
`IPR 2015- 01796, in which Cox Communications
`challenges the same patent, has been joined with this
`proceeding.
`
`Each side has 60 minutes to argue.
`Petitioners have the ultimate burden of
`establishing unpatentability and will argue first.
`Petitioners also may address their motion to exclude, if
`you choose, in your opening argument. Patent Owner
`then will respond to Petitioner's arguments and may
`address its own motion to exclude, if you choose to do
`so.
`
`Next, Petitioner may use any time it has
`reserved for rebuttal to respond to Patent Owner's
`arguments. And, finally, Patent Owner, if you do
`address the motion to exclude in your opening argument,
`
`
`
`4
`
`
`
`Case IPR2015-00635
`Patent 5,563,883
`
`you may reserve some time for rebuttal to respond only
`to Petitioner's arguments on that issue.
`Judge Quinn is joining us by video from our
`Dallas office, and will not have the benefit of visual
`cues in the room. So, please, when you speak about an
`exhibit or demonstrative, begin by identifying it with
`specificity, including the particular page or slide
`number. Also please be sure to speak into the
`microphone so that Judge Quinn can hear you.
`Counsel, when you begin your argument,
`please identify yourself for the record and the party you
`represent.
`
`Petitioner, you may begin when ready. And
`would you like to reserve any rebuttal time?
`MR. SOMMER: Yes, Judge Pettigrew. I
`would like to reserve 20 minutes for rebuttal.
`JUDGE PETTIGREW: All right. You may
`
`begin.
`
`MR. SOMMER: May it please the Board,
`Andrew Sommer on behalf of ARRIS Group, Inc. Today
`I'm here with Michael Turton, who is here on behalf of
`Cox Inc.

`panel that's present here. I understand the remote judge
`will have them electronically. Would you like them?
`JUDGE PETTIGREW: I would like a copy.
`MR. SOMMER: Okay. May I approach?
`JUDGE PETTIGREW: Yes.
`MR. SOMMER: So this proceeding
`challenges the validity of U.S. Patent 5,563,883. In
`turning to slide 2 of our demonstrative, we have a couple
`of graphics from the '883 patent to just provide, by way
`of overview. We think the institution decision actually
`has a fairly accurate summary of what the patent itself is
`about.
`
`This particular patent has three claims that
`are being challenged. They are all method claims.
`Those claims pertain to the use of a particular type of
`system that has a central controller, a plurality of remote
`terminals, and a shared transmission means.
`And the central controller and the remote
`terminals are allocated particular types of channels
`called signaling data channels. And those channels are
`initially assigned according to the method, and they can
`be reassigned by the central controller, according to the
`claim method.
`Here we have some figures on the
`right- hand side of slide 2 that show the difference

`
`Case IPR2015-00635
`Patent 5,563,883
`
`between two types of channels discussed by the patent.
`There are bearer channels, which carry primarily user
`data, according to the patent, and then there are
`signaling data channels, which carry signaling data.
`They are also referred to as control channels.
`The '883 patent includes a number of flow
`charts, but this is just one exemplary flowchart. And
`this is one that the expert testimony refers to as a
`process that shows the reassignment and assignment of
`terminals, as well as several other processes that are
`described in the patent.
`This particular figure starts with a terminal
`request. And if you follow the various flows down
`through the bottom, it ends with the issuance of a
`command to the terminal to either tune or retune to a
`particular channel. And the step of terminal assignment
`is shown here in 230.
`Now, this particular figure was annotated
`for the purposes of Dr. Heegard's deposition. You'll
`note that the figure in the patent doesn't actually have
`these numbers. It just provided a convenient way to
`facilitate discussion about this particular figure.
`So '883 patent, claim 1, this is slide 4 of the
`demonstratives. This claim is the only independent
`claim that is being challenged here. There's a rather

`Patent 5,563,883
`
`lengthy preamble. And it defines the type of system that
`this method needs to be performed in. It says in a
`multiple-access communications system.
`We are going to have a central controller, a
`shared transmission means, and a plurality of remote
`terminals. And then there's going to be a method of
`allocating signaling data channels between the central
`controller and the plurality of remote terminals from a
`plurality of communication channels, and of assigning
`those terminals, comprising a number of steps which
`we've called in our briefing steps 1A through 1E.
`The first of the steps is establishing
`communications between the central controller and the
`plurality of remote terminals via a plurality of signaling
`data channels. And each of the terminals needs to be
`initially assigned to a pair that's predetermined. And we
`can discuss how our proofs meet that. But one example
`is the single hand -- single-channel hunt sequence
`followed by normal operation in that the remote terminal
`performs a single channel hunt based on what's stored in
`its memory, and attempts to communicate on that
`channel using the process described by the MPT
`specifications.
` Step B is monitoring the status of a
`plurality of signaling data channels in use between the

`
`central controller and the plurality of remote terminals,
`and they monitor for usability of those channels. Step
`C, determining whether one of said plurality of remote
`terminals needs to be reassigned to a different signaling
`data channel other than the predetermined signaling data
`channel. This is a particular limitation that the parties
`dispute.
`
`It's fairly clear to me that the dispute is
`really one of claim construction. And the question here
`is does this step need to be performed by a central
`controller, which we'll get to that in our discussion this
`afternoon.
`
`Step D, determining whether a different and
`suitable signaling data channel is available, other than
`the predetermined signaling data channel. And then the
`final step, which is another disputed step, reassigning by
`said central controller, said remote terminal to a
`different and suitable signaling data channel for
`communications henceforward.
`So this particular limitation is another one
`that the parties have disputed the meaning of and ha ve
`disputed whether the actual proof that has been put in
`actually satisfies this limitation.
`JUDGE QUINN: Counsel?
`MR. SOMMER: Yes.

`Case IPR2015-00635
`Patent 5,563,883
`
`
`JUDGE QUINN: Just a question regarding
`the claim construction of terms. We understand that
`there has been at least one claim construction in District
`Court, but we are not aware of others, other than Exhibit
`1004.
`
`Are there any additional orders on claim
`construction regarding the terms in dispute here?
`MR. SOMMER: It is my understanding that
`there is a second claim construction order that is coming
`out of the Eastern District of Texas. I'm happy to put
`that on file with the panel, if they would find that
`helpful.
`
`JUDGE QUINN: We'll discuss that and let
`
`you know.
`
`MR. SOMMER: Okay.
`JUDGE QUINN: Thank you.
`MR. SOMMER: Yes. So the reassigning by
`said central controller has to reassign something
`specific.
`
`The claim says it has to reassign said
`remote terminal.
`What is the remote terminal reassigned to?
`It's reassigned to a different and suitable
`signaling data channel. And why is it reassigned? It's
`reassigned for communication henceforward.

`

`
`
`So claim 3 is a dependent claim. And it
`further limits the steps of the monitoring of the status of
`the plurality of signaling data channels for Step B of
`claim 1. It requires a number of other processes. This
`claim is subject to ground 2 of the channel on which the
`Board had instituted trial. And on this particular claim,
`we've shown how MPT, the three MPT specifications in
`view of Zdunek and Dufresne render obvious this
`particular claim.
`And then Claim 4 is another dependent
`
`claim.
`
`It refines Step 1C of Claim 1. And it
`requires a sensing of the status for overloading to
`determine whether the remote terminal needs to be
`reassigned, and sensing the status of the signaling data
`channels for failure to determine if the remote terminal
`needs to be reassigned.
`So, one of the big disputes that has come up
`in the briefing are whether the MPT specifications
`constitute printed publications. We submit they
`absolutely do. The evidence shows that these were
`copyrighted first in 1988, revised and reprinted in 1991,
`and that there is substantial evidence showing that not
`only were they actually printed, but the RA or the
`radiocommunication agency, which is an agency under
`
`
`
`11
`
`
`
`Case IPR2015-00635
`Patent 5,563,883
`
`the Department of Trade and Industry in the United
`Kingdom, made these available for free in its library.
`They were available upon written request.
`There's a phone number, a 24- hour number, if it's that
`urgent to get a copy of these particular specifications.
`And the document itself says the specifications are
`published by between April 1, 1991, and March 31,
`1992, well before the 102(b) critical date.
`So, these specifications were not some
`well- kept secret that was lurking in a library in Peru and
`never indexed and sitting on a shelf. The prior art
`shows a number of instances in which the MPT
`standardization process, regardless of whether I
`understand that there's a question of whether, well, of do
`these particular references reference the '91 version that
`we've put into evidence, or do they refer to the earlier
`1988 version.
`We submit that that's really not the relevant
`question as to why we are using these particular pieces
`of evidence. It shows that those skilled in the art were
`aware that the radiocommunications agency h ad
`promulgated standards. They knew the standards body
`that was involved in the standardization process, so that
`would have naturally led them to the RA to see if there

`
`were updated versions, which the evidence shows were
`freely available.
`These particular standards were discussed
`during FCC rule-making proceedings for trunked radio in
`the United States. And that's Exhibit 1032. And this is
`slide 10. At the bottom, we see that there's a footnote.
`Some of the telecommunications industry stalwarts were
`discussing whether or not MPT should be used here in
`the United States as well.
`This document is dated 1989, obviously
`cannot be referring to the 1991 version of the standard.
`But, nevertheless, it shows the awareness to those
`skilled in the art about the standardization of these
`standards and where to go to get them. The British
`Department of Trade and Industry had promulgated these
`standards. So we submit that the standards themselves
`are printed publications.
`So the overview of the MPT functionalities,
`we've got a number of slides. These are discussed in the
`petition and the supporting declaration in some level of
`detail, some of them up to six pages of discussion. So
`we obviously don't have time to repeat all that here, but
`I'll hit the highlights.
`The MPT functionalities define two real
`primary pieces of equipment. There are others like base

`
`stations in the network, but the TSC is the brains behind
`the operation. It is the trunk system controller, trunking
`system controller. And that talks to radio units that are
`distributed throughout the network.
`And there are a number of ways these
`networks can be set up. There are a lot of options in the
`standards, but one of those ways is to distribute them
`among different fleets and different populations so that
`the radio units can be moved from one area or one set of
`frequencies to another, for example, or multiple fleets
`can be operated on a single network based on use of
`different frequencies.
`And here you see that there are forward
`channels and return channels, just like in the patent.
`There are forward control channels and reverse control
`channels. And they are always used in pairs. And that's
`because the frequencies need to be separated. And that's
`what we are showing here in this demonstrative.
`So, this is a bit of a -- bit of a spaghetti
`mess here. But what I will submit is that this chart
`shows the flow of various processes with citations to the
`individual sections of the standard, to help the Board
`navigate exactly how these pieces fit together. And we
`do so -- we explain this in the petition, pages 10 through
`16, in fairly exhaustive detail.

`
`
`This particular diagram shows all three of
`the types of functionality that are really at play in the
`two use cases that we've articulated in the petition.
`The first is the single-channel hunt
`sequence, which appears in top right of slide 12. And it
`goes over into the registration process.
`If registration is granted, we have normal
`operation, which is in the big white box on the
`right- hand side of slide 12.
`And then we have fallback operation which
`appears on slide 12 in the lower left- hand corner. And it
`shows how fallback mode operation can result from a
`switch from normal operation and can be exited by going
`back and performing channel hunt procedures by the
`remote terminals. We'll get into a couple more of the
`more relevant functionalities here in a moment.
`This is another flow chart that you'll find in
`the petition. The petition articulates exactly what this is
`showing, but, suffice it to say, this is particularly
`relevant. This is slide 13. And it's particularly relevant
`to the MPT functionality at issue for use case 1, which
`is our single-channel hunt theory, followed by normal
`operation.
`
`And these are a series of decisions that the
`remote terminal has to perform before it can even ask to

`
`communicate on a control channel, which is the series of
`steps to the right- hand-most side of this demonstrative.
`So, skipping ahead a few slides in our deck.
`JUDGE QUINN: Counsel, I don't see a
`more detailed explanation of the fallback operation or
`the fallback procedures.
`Are you only relying on the single-channel
`hunt sequence now?
`MR. SOMMER: Not at all, Your Honor.
`JUDGE QUINN: Okay.
`MR. SOMMER: Not at all. The way that
`the briefing breaks down as to the fallback mode is that
`there are two primary arguments as to why
`single-channel hunt does not meet the claims. One is
`that it doesn't meet Step 1C, and one that it does not
`meet Step 1E. We obviously contest that, but the same
`arguments are made with respect to the fallback mode.
`There's only one unique argument as to
`fallback mode. And that is that step C must depend
`upon the output or the result of the monitoring Step B.
`So as to that particular argument, and as we've submitted
`in our reply, that argument seems to exclude
`embodiments from the specification inappropriately and
`rests solely on expert opinion as to why that needs to be
`the case.

`Case IPR2015-00635
`Patent 5,563,883
`
`
`For example, there is an example given in
`Figure 6C. And we can get back to that. Figure 6C of
`the patent, Exhibit 1001, we can look at slide 3, has an
`example in which the terminal makes a request. And if
`it's a registration request, the process flows down the
`right- hand side of the figure. And it determines whether
`it's a newly registered terminal.
`In the instance in which the central
`controller says this is not a newly registered terminal, I
`already hold a registration for this terminal, it makes an
`assumption. And the assumption is that the terminal had
`had a channel failure. And, therefore, is requesting a
`new registration because of that channel failure.
`And so it goes into the block that was
`actually renumbered during Dr. Heegard's deposition as
`180. But you can see it's also in Exhibit 1023, which
`was put in the record as part of our reply. And that is
`channel failure processing in which it goes down into
`the second half or the bottom half of the figure. And it
`then reassigns that terminal to a different and suitable
`channel based on this failure processing.
`So we submit that that embodiment would
`be excluded by requiring Step B to feed into Step C,
`notwithstanding the language of the claim which really
`doesn't suggest that on its face.

`
`
`JUDGE PETTIGREW: Well, does a claim
`have to include every embodiment in the patent?
`MR. SOMMER: Not necessarily. If there is
`a good reason not to include an embodiment within the
`patent, or if there's a reason to include that the inventor
`claimed distinct embodiments in distinct claims, you
`obviously do not construe the claim as trying to cover
`every embodiment because you can end up with
`unreasonable claim constructions.
`But on the language of the claim, and
`particularly Step C, there's really no reason to read Step
`B or an output of the monitoring step into Step C, which
`is simply a determination that it needs to be reassigned.
`If it had said something like it needs to be
`reassigned based on the monitoring, that would be an
`entirely different circumstance than we have here.
`JUDGE PETTIGREW: So that argument is
`based on the plain language of the claim, rather than the
`fact that it excludes an embodiment?
`MR. SOMMER: Well, our argument is
`based first on the plain language of the claim, following
`the Phillips rubric of claim construction. We look first
`to the language of the claim. The name of the game is
`the claim. I think we put that at the beginning of our
`reply.

`
`
`We steadfastly believe that in this case that
`doctrine really resolves pretty much all of the disputes
`as to whether the prior art fits within the claim. But
`beyond that, the intrinsic evidence of the specification,
`which is highly persuasive in claim construction, does
`suggest that excluding that embodiment, you probably
`need a very good reason to do so.
`JUDGE PETTIGREW: Thank you.
`MR. SOMMER: You are welcome. So,
`moving on, to -- Judge Quinn, did I answer your
`question about fallback mode?
`JUDGE QUINN: Yes. Thank you.
`MR. SOMMER: Now I would like to move
`on to the proofs regarding Step C. And this can be
`found on slide 20, which is really just a collection of the
`record cites that we have for our support for this -- I'm
`sorry, actually, I would like to focus on slide 19. So it's
`the single-channel hunt.
`As I said, I think the dispute on Step C
`really boils down to the same dispute but for that C
`depends on B argument that we just spoke about. So in
`single-channel hunt, the radio unit is confirmed and
`operating on a control channel because it's confirmed it.
`It's obtained a registration or determined it
`did not need to register. And it's monitoring the channel
`
`

`
`Case IPR2015-00635

`
`for usability criteria, such as code word sample error
`events or performing a background search, looking at
`other frequencies that the radio unit itself can hear to
`say, you know, is there a better channel for me out
`there.
`
`And if there is, it makes a decision, which
`is a computer-implemented process that's contemplated
`expressly by the standard, to leave the control channel.
`I'm going to let go of this control channel, and I'm going
`to go find another one. And there are a number of
`criteria expressed by the standard.
`For example, a number of unsuccessful
`attempts to communicate. If it's on a channel, and it
`makes a request to say send a data message to another
`user, and it tries that a number of times, it can say I've
`been unsuccessful so many times. I'm going to look for
`a new channel. There must be a problem here.
`And so in that respect the remote terminal
`is making a determination of whether one of said
`plurality of remote terminals needs to be reassigned to a
`different signaling data channel other than the
`predetermined signaling data channel.
`So moving ahead to sl ide 21, and as I
`foreshadowed in the argument here, the real argument is
`does the central controller need to perform the

`
`determination step, because as you've he ard, the remote
`terminal or the radio unit of MPT is performing the
`functionality that we've identified in petition. I don't
`think there's really any dispute about that.
`JUDGE QUINN: I want to ask you about an
`argument that Patent Owner has made that you've taken
`the position in District Court that the central controller
`is the key element of all of the steps that are claimed in
`the independent Claim 1.
`MR. SOMMER: So --
`JUDGE QUINN: And you made that
`statement in connection with your claim construction
`hearing. I would like to hear your response to that.
`MR. SOMMER: So the statement made
`during the claim construction hearing, and my
`recollection of that particular statement was during an
`exchange with the judge about the claims. And let me
`find that particular statement. It says the central
`controller plays a key role in Steps A through E.
`To the extent that that was actually adopted
`by the District Court, which we submit it wasn't, you
`know, that might raise a different question here. But
`whether or what is a central role in this step, we submit
`that that doesn't mean that the central controller actually
`has to perform the determination. Obviously the central

`25
`
`Case IPR2015-00635
`Patent 5,563,883
`
`controller is part of the claim. It does play a role in the
`various steps.
`In the determination, it's emanating the
`signals that are being sensed for error. So this
`particular statement we submit, first of all, is
`ambiguous, but in any event, certainly not binding or a
`reason to construe claim limitation 1C as being
`performed by the central controller.
`And the intrinsic record I think is very
`telling on this particular limitation. And specifically if
`we look at Claim 1, Claim 1 only says that a particular
`step needs to be performed by a particular piece of
`equipment that is the central controller one time. That
`is limitation E. That was added by amendment,
`intentionally, by the inventor during prosecution to
`distinguish over some prior art.
`So where the inventor wanted to say that a
`particular step needed to be performed, the step of
`determining, for example, he knew how to do it. If he
`wanted Step 1C to be limited to being performed by
`central controller, it was a simple matter of claim
`drafting. He left the claim broad.
`Claim 2 shows us the same thing. You've
`got polling by a central controller, sensing by a remote
`terminal, and a step of responding to the polling by the
`
`
`

`
`Case IPR2015-00635
`Patent 5,563,883
`
`central controller. And the response is from the remote
`terminal.
`
`So, we have a number of steps here in which
`the inventor intentionally made reference to the specific
`piece of network equipment that needed to perform the
`given step.
`
`Step C, we have that missing. So the claims
`themselves suggest that Step 1C is not so limited. We
`submit that the patent also, the specification also
`supports this construction that the inventor didn't intend
`to limit the claims on the determining whether the
`terminal needs to be reassigned to an embodiment in
`which the central controller must do the reassignment.
`And that is in Figure 6. In discussing this
`particular text, Dr. Heegard, Patent Owner's expert, was
`asked what types of examples, and this is from the
`perspective of a person of ordinary skill in the art, and
`this can be found on slide 23. From a perspective of a
`person of ordinary skill in the art, what kinds of
`terminal requests does this process in Figure 6 of the
`patent receive?
`And one of the things that it receives is a
`request for reassignment. And so the remote terminal
`can request reassignment. It has that right. It could ask
`to be reassigned. And in that instance, it's the remote
`

`
`Case IPR2015-00635

`
`terminal that's making the determination that it needs to
`be reassigned.
`Additionally, I would like to point out that
`while Dr. Heegard in this particular proceeding has
`submitted some testimony saying that Step C needs to be
`performed by the central controller, he's taken a
`different position when testifying under oath in 2013, as
`to the interpretation of the claims.
`And he was asked during deposition: Can
`you tell me, in your understanding of the claim, what
`other steps in Claim 1 must be performed by the central
`controller?
`
`And his answer was: Well, we talked
`earlier that the monitoring has to be available to the
`central controller. The only thing definitely the central
`controller does is reassigning, because it explicitly says
`that.
`
`And I think he stated our position exactly
`right. Where the claim says what needs to do a
`particular step, the claim is so limited. But where it
`doesn't, it's not limited to any particular piece of
`network equipment performing that step.
`And he made an assumption when he
`actually applied this in his infringement analysis. He
`didn't assume that any of the other limitations were to be

`
`Case IPR2015-00635

`
`limited in the way that they now submit the claim should
`be limited.
`
`So we submit that the claim construction
`that was adopted in the i nstitution decision is consistent
`with the intrinsic record, and that the extrinsic record
`certainly doesn't justify deviating from that claim
`construction.
`JUDGE BENOIT: Mr. Sommer, doesn't the
`question in Step C, determining whether one of said
`plurality of remote terminals, doesn't that suggest that
`the central controller would be making that
`determination?
`MR. SOMMER: We submit that it doesn't.
`It's simply a determination about one of the terminals.
`And things can make determinations about themselves
`all the time. I made a determination that I am going to
`show up here today and make this argument. I
`determined that I was going to go to law school. And
`that allowed me to be here.
`But, you know, my car determines it needs
`an oil change every 3,000 miles. It lets me know. My
`computer determines that it needs to reboot after
`receiving a software update. These types of things
`happen all the time in systems. And they can make
`determinations about themselves.

`
`
`I don't think that the language of Step C is
`so strong as to preclude a self-determination by one
`remote terminal. If it had been about multiple remote
`terminals in the context of this patent, that might have
`been a very different circumstance.
`JUDGE PETTIGREW: I think we
`understand -- I see you have got slides now with respect
`to Step D. I think we understand the arguments with
`respect to Step D. You may want to move on to Step E,
`which I think is a major point of contention.
`MR. SOMMER: Thank you, Your Honor.
`So, Step E, we've got some discussion here on slide 28.
`And as I mentioned at the beginning, in focusing on the
`language of the claim, the claim requires reassigning by
`the central controller. So a central controller has to
`perform this step of reassigning.
`What is reassigned? The remote terminal.
`And where is it reassigned to? A different and suitable
`signaling data channel for the purpose of
`communications henceforward.
`And so focusing on the analysis presented
`in the petition as to how single channel hunt followed by
`normal operation on a control channel actually meets
`this particular limitation, Petitioner submits that the
`registration process itself leads the TSC to reassign the
`
`
`
`26
`
`
`
`Case IPR2015-00635
`Patent 5,563,883
`
`remote terminal because it gives the remote terminal
`access to that channel.
`Now,
