`JUDGE PARVIS: Good afternoon, everyone. This is the oral
`
`argument in IPR2016-01259, and IPR2016-1261 through 1263.
`
`These inter partes reviews involve the challenged patents, the same
`three that we discussed this morning, U.S. Patent Nos. 7,764,777 B2;
`8,155,298 B2; and 8,457,113 B2.
`
`Petitioners are Bright House Networks, LLC, WideOpenWest
`Finance, LLC, Knology of Florida, Incorporated, and Birch
`Communications.
`
`Patent owner is Focal IP, LLC.
`
`As a reminder, the petitioners jointly filed the petitions and will be
`expected to speak with one voice.
`
`The same ground rules explained this morning apply to the
`presentations this afternoon.
`
`Now, petitioner -- counsel for the petitioner, will you please
`introduce yourselves and those with you.
`
`MR. TYSON: Yes. Thank you.
`
`Good afternoon, Your Honors. Chris Tyson with Duane Morris for
`the petitioners. With me is Pat McPherson, also of Duane Morris, for
`petitioners. And I have Wayne Stacy and Jay Schiller of Baker Botts,
`and Jaspal Hare of Spencer Fane.
`
`JUDGE PARVIS: Patent owner.
`
`MR. BUMGARDNER: Good afternoon, Your Honors.

`

`
`JUDGE PARVIS: Thank you.
`
`So any time you're ready, Counsel for the petitioner, you may
`proceed.
`
`MR. TYSON: Thank you, Your Honor.
`
`May it please the Board, good afternoon again, Your Honors. I'd
`like to reserve at least 20 minutes for rebuttal.
`
`The purpose of the hearing today is to direct the board to evidence
`of record that supports dispositive facts that are in our petition.
`
`Now, per our request for oral argument, we had spoken with the
`petitioner at Cisco. And in the interest of the Board's time and as we
`forth in that request, we will not be repeating overlapping arguments
`between the two cases.
`
`Now, there's been a lot of papers filed in these cases, but there
`really are many common issues that persist across the IPRs.
`
`And so the arguments today, what I'd like to do is just focus on just
`a few common issues that we think are -- that we submit are dispositive
`of the case.
`
`And with that, I think it's useful to discuss the challenged patents,
`actually to provide a foundation for the state of the art and the grounds.
`
`And I'm putting on the Elmo here, this is page 4 of the Board's
`institution decision in the '113 patent. And this is for the '113 patent, but
`it applies equally. All the patents, as we know, share a common
`specification.
`
`So what I'd like to point out -- and the Board has already reflected
`
`1

`Case IPR2016-01259 (Patent 8,155,298 B2)
`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`this in its annotations -- is that there is no secret sauce in the switches that
`are in the PSTN. There is no secret sauce in the signaling system that the
`PSTN uses, SS7.
`
`And, essentially, there is also all the signaling switches that passes
`in between those switches. There's no secret sauces. That's not where --
`what the patents are talking about.
`
`The patent doesn't disclose any new signaling. Now, signaling is
`an important term. And it's been a little bit glossed over this morning. I'd
`like to talk about signaling. Are those signaling messages that are sent to
`set up, to create a path for establishing voice communication?
`
`So that applies equally to both circuit switch and packet switch
`networks. Here we're talking about the PSTN, circuit switch network.
`
`Now, also in this drawing, in this Figure 1, which is really,
`essentially, the first -- one of the embodiments of the patent, we have
`what's called this web. And we have a user interface and we have a
`device there that connects to the web.
`
`Now, there's no secret sauce in the web. That web is not a cloud.
`It's -- you know, it's thousands of routers that flow in between that
`communicate messages back and forth, that packetize messages.
`
`And the use of the web here, depicted in Figure 1, as a portal by
`which a subscriber -- or it could be also the calling party if they're a
`subscriber -- can connect into the Internet -- connect to the Internet,
`through the web into a web server to add and change call control
`information, the patent acknowledges there's no secret sauce there either.
`
`So all of this is conventional. The patent acknowledges it's
`

`

`

`Case IPR2016-01259 (Patent 8,155,298 B2)
`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`conventional. The use of those -- the use of signaling, all of that, is
`conventional.
`
`So what we have left here is this tandem access controller. Okay.
`
`And there's a second embodiment that the patents illustrate, and
`I'm going to put that up shortly. And that's in Figure 2 of the patent.
`Essentially, really the difference between these two is -- this is Figure 2
`of the '113 patent.
`
`And, essentially, the difference here is that we have simply added,
`as we've shown here, the web. The web here. And now the web is used
`to send conventional voice over IP, abbreviated here as VoIP.
`
`So it's conventional signaling, conventual voice communication.
`All of this is conventional. It's done using, as the patent describes,
`conventional equipment, a conventional VoIP capable digital telephone.
`
`And so there's no secret sauce there.
`
`Now, the patent owner this morning talked about the fact that
`there's a bidirectional arrow here between the web and the TAC. And I'll
`note for the board that that is the only disclosure in the patent of calls and
`signaling that go in between these two networks, between the VoIP
`network and a PSTN network, so between that IP network and the PSTN.
`
`And when I asked the patent owner's expert, and I'll show you
`some of that later, he acknowledged that, yeah, that's all conventional.
`Everybody knew how to -- how to translate signaling between the two.
`
`So there didn't need to be any more disclosure than this one
`bidirectional arrow. That is the only disclosure that covers that.
`
`So, again, what is this secret sauce? What are we looking at? The
`
`1

`Case IPR2016-01259 (Patent 8,155,298 B2)
`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`TAC, right? The TAC.
`
`Okay. Well, the patent thankfully gives us a little bit more
`background on what the TAC is and what the TAC is not.
`
`So the first thing I'd like to do is just point out a couple places
`where the TAC identifies -- gives us a little bit more information on the
`TAC. And I'm going to the '113 patent. This is column 4. And what I'd
`like to look at right here for now is -- I'm going to focus you on this line
`right here. So this is column 4, line 39 to 42.
`
`And what it says here is that, The TAC 10 may use any
`combination of hardware, firmware, or software and, in one embodiment,
`is a conventional computer.
`
`So what that tells us is the TAC -- there's no secret sauce in the
`hardware, there's none in the software, there's none in the firmware. And
`it could actually just be a conventional computer, the TAC itself.
`
`Okay. Well, what else do we know from the patent?
`
`Again, we're going to go to the '113 patent, and I'm going to start at
`column 6. And I'm looking right here.
`
`And what does this tell us? It says, first: The TAC may be
`implemented by using conventional processor hardware.
`
`Okay. That's like we'd said before. There's no secret sauce in the
`hardware.
`
`Okay. What else does it say?
`
`Devising the software/firmware used to control the TAC is well
`within the capability of those skilled in the art since the various control
`features that can be made available are generally already known.
`
`1
`2
`3

`

`Case IPR2016-01259 (Patent 8,155,298 B2)
`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`Okay. So there's no secret sauce in the programming of the TAC.
`
`Programming the software, programming the firmware, there's no secret
`sauce there.
`
`And on the same -- going to the opposite column here, I'm looking
`right here. This is column 5, line 25 to 35. Actually, it's line 26 is what
`I'm looking at.
`
`And it says here that: Examples of features that can be selected by
`the subscriber include -- and it identifies a number of well-known
`telephone features.
`
`And it goes on to say -- the patent goes on to say that: These
`features can be implemented in the TAC using known software
`techniques since such features are known.
`
`Okay. So all the call processing, the call processing associated
`with these telephone features -- how to connect a call, how to -- how to --
`that sent SS7 signaling, the signaling that sent -- all of those features are
`identified as providing -- as just being done in their conventional way.
`There's not any new call processing that the patent is talking about here.
`It's identifying this.
`
`And so what do those features include? Well, they include call
`blocking. Well, that's a term that's in the claims. Well, this is the
`admission that whatever it says about call blocking, that's well known.
`That's conventional. Call forwarding, the same. Time of day conditions.
`Follow me. All of these different things. Routing to voicemail. Right up
`here.
`
`
`All of those are well-known conventional features that the TAC
`
`1
`2
`3
`4
`5
`6
`7
`8
`9
`10
`11
`12

`

`Case IPR2016-01259 (Patent 8,155,298 B2)
`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`implements using known software techniques.
`
`So there's no secret sauce in the call processing that the TAC does.
`It can't. So if there's no secret sauce in the hardware, the software, the
`firmware, programming the TAC, programming the software/firmware,
`and there's no secret sauce in the call processing, well, what's left?
`
`Okay. So if we look back at Figure 2, and here's our Figure 2. And,
`again, just like Figure 1, there's no secret sauce here, no secret sauce
`here, no secret sauce here. There's SS7, no secret sauce there. In the IP
`signaling, there's nothing there.
`
`Okay. So what's left?
`
`Well, what the patent talked about is that -- here, if I have -- here's
`my -- this a Class 5 switch. If this Class 5 switch, if this is my
`subscriber, 20 here, if that -- if this Class 5 switch is where I control my
`call processing, if this is the control of my call processing -- and they
`identify a number of disadvantages that may be achieved from that.
`
`If this is where my controller is inside that Class 5 switch, there
`may be a number of disadvantages to that.
`
`So what does it say? It says, okay, well, if we make that
`centralized, if we put it somewhere other than that switch, we have a
`centralized control, that will provide some advantages. It identified.
`
`And now what I'll point out is that all of those advantages that are
`described in the specification are not for PSTN to IP calls. They're not for
`the IP network. They're for PSTN calls only. They do not apply to this
`scenario.
`
`So those advantages are not advantages of this. In fact, if you look
`
`1
`2
`3
`4
`5
`6
`7
`8
`9
`10
`11
`12
`13

`
`

`

`Case IPR2016-01259 (Patent 8,155,298 B2)
`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`at the specifications, it's going to identify that VoIP didn't have any of
`those disadvantages. It didn't. It had different ones.
`
`It may have had a different -- a better user interfacing control, but
`that's it.
`
`So all those advantages that we talked about this morning do not
`apply to this Figure 2 embodiment when we're talking about calls that are
`going across both networks.
`
`And so what we do is we look at -- so that really doesn't help us
`too much, because I'm still wondering, well, what's the secret sauce here
`on these patents?
`
`So we go to the patent owner's response. And I'm looking at the
`patent owner response on page 10 -- again, this is from the '113 patent.
`And I want to focus right here.
`
`And here we have a quote from their response. And what it says
`is: Handling calls at the tandem level maintains the quality of the call as
`it is processed within the PSTN where the signal may be in digital form
`and/or carried over high-quality lines.
`
`Okay. So what the patent is saying, what the patent owner has
`acknowledged and stated is that implementing -- it doesn't say anything
`about call features here in that. It doesn't say anything about call
`processing.
`
`What it's saying is that if I implement well-known call processing
`where the signals can be maintained in the digital form, that's where
`they're in the tandem level. Then I can get a number of advantages. So
`that's the secret sauce if I'm -- if I am handling those calls where they can

`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`be in digital form.
`
`All right. And so with that background, let's go to the claims. And
`for purposes of the hearing today, I'm going to just talk about -- discuss
`the '113 patent, Claim 1.
`
`In that claim, we submit, and I think the testimony this morning
`kind of confirms that, that this is representative. This is a representative
`claim for all the claims before the Board.
`
`Now, I'm going to go over this briefly because we've already
`talked a lot about this claim already this morning. And it is a very dense
`claim. It doesn't really fit on here.
`
`And so what I'm going to say is -- the things that I want to point
`the Board to that we think are important here: One, it's a call that goes
`across a packet network. So we have a call across a packet network. We
`have this call across the second network. Okay. And their expert has
`identified that the second network is the circuit switch network or the
`PSTN.
`
`And then we have two limitations in this. Those are the two
`limitations we talked about this morning. I'm not going to belabor them.
`But for purposes of brevity, I'm going to identify that those limitations
`are -- there we go -- the call processing system coupled -- I'm going to
`call that the switching facility limitations. And then we have this
`establishing the communication limitation. And I'm going to call that the
`call connection limitation. I think they were called something very
`similar and addressed by both the patent owner and the petitioners this
`morning.

`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`And what I'd like to point out -- and, actually, I'm just going to put
`
`this back up again for one second. This limitation, the petitioners in
`YMAX identified this morning -- this switching facility limitation here.
`
`If the board rejects patent owner's construction and its narrow
`interpretation based on the disclaimer, then this switching facility --
`there's no rebuttal -- this switching facility is found under our grounds as
`well.
`So the only limitation in dispute if the patent owner -- if the Board
`
`rejects the patent owner's construction is this establishing the call
`connection limitation.
`
`Now, with that, what I'd like to do first is -- unless the Board has
`any questions -- I'm going to address that switching facility limitation
`first.
`And the way I'm going to address it for purposes of this hearing is
`
`I'm going to show that Archer discloses that switching facility limitation
`using the patent owner's construction.
`
`So this narrow construction that the patent owner is trying to have
`you adopt, Your Honors, for purposes of the hearing, I'm going to walk
`through how Archer discloses that limitation using their construction.
`And we're going to start with Figure 2 from Archer.
`
`Now, what Archer is, Archer is explicitly about telephony. And it
`is explicitly about converging networks where we have a circuit switch
`network, like the PSTN, and we have a packet switch network, like the
`Internet, like an IP network.
`
`And this is -- and Archer is specifically about PSTN, calls between

`Case IPR2016-01261 (Patent 8,457,113 B2)
`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`PSTN and VoIP, calls between circuit switch network and IP networks.
`And it is explicitly about voice over IP.
`
`Now, that is -- if you note, that is exactly like the claim. So it's in
`that same frame as the claim. We're talking about calls across two
`different types of networks, those converging networks.
`
`Now, the signaling, how this works -- and we'll just talk about this
`a little bit. There's signaling that comes from the phone. It's converted to
`the SS7 signaling in the PSTN.
`
`Okay. That SS7 signaling, in embodiments, will pass to this
`gateway. The job of the gateway is to translate the signaling, the voice --
`everything it receives -- translate that into the IP network.
`
`Okay. And then what -- then you get down here to this server
`processor 128 right here. This is the brains of Archer. And the brains in
`Archer, what it does, it receives that signaling message. And based on
`information in that message -- could be a phone number -- you know, the
`phone number, okay, it's calling the phone number.
`
`It receives this message. This is where the call processing -- you
`know, this is part of the call processing system. It's going to do a lookup
`in the database. Based on that lookup, it may say, Well, this subscriber
`wants me to call a number of different numbers at the same time.
`Because it -- we want to make sure that we find where he is.
`
`And so what it does is the server processor then initiates new call
`requests. It initiates a call request out, let's say, to this computer 134a,
`which is not a voice-over-IP-capable computer. It may send signaling
`back through the converter, back to the PSTN to another switch, or

`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`through another converter. The point being that that signaling message is
`going out, and at this time it's all signaling. That's what we're talking
`about.
`
`That signaling goes out and when -- Archer is very explicit on this
`point -- when it's -- let's say this computer 134a is the first of those calls
`to pick up, somebody picks up the phone. I get an answer message. It's a
`call to pick up notification, an answer message. That answer message is
`received by the server processor, and then the server processor will then
`connect the calls together.
`
`I think we've talked about that a lot. Again, that's conventional.
`That's how this works. That's how conventional call processing works.
`
`If you're doing call forwarding, if you're doing branch calling,
`especially when you're talking about two different networks, you're going
`to hold that first call here, and then you're going to try to connect it.
`
`That's how it's done. When the patent is talking about all those
`different telephone features, it's just saying, we're doing it just the way it
`was already done. And that's not part of the secret sauce.
`
`So what we have here in Archer is then -- now, what I'll say is that
`in our petition -- we're going to point to this in the petition. In our
`petition, we set forth -- so this is from our petition, and there were a
`number of different alternatives that were set forth in our petition.
`
`And our petition identified that, you know, depending on the
`construction -- depending on the construction of the term switching
`facility, that can impact how Archer can read. But in any event, there are
`a lot of different ways that we set forth that -- that this would be -- that

`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`Archer would render the claims obvious.
`
`And so here, what we say specifically, is: Archer's web-enabled
`processing system includes converters coupled through packet switch
`network 130 to server processor 128 coupled to database 138.
`
`So we identified the TAC here in this particular element as
`including all three of those different components.
`
`Now, the patent owner -- and I'm just going to leave that up for one
`second. The patent owner has made a big deal in its motion to strike.
`And it's alleged that this is a new argument, that we didn't identify that
`those three components were there.
`
`And I'm not just going to look at the petition. What I'd like to do is
`show you -- this is from their patent owner response -- the patent owner
`response -- whether we identified that these three components in one
`reading of Archer could be part of the TAC.
`
`And we're just going to look at this top page. This is page 63.
`And this is just one example. We've identified a number of examples for
`Your Honors in our responsive listing that was issued pursuant to the
`motion to strike.
`
`Let's just take a look at this first sentence: With respect to
`Grounds 1 and 2, petitioner argues that Archer teaches and renders
`obvious a web-enabled processing system configured as a tandem access
`controller in the form of its server processor 128 and database 138 and
`converter gateways 126-32.
`
`Okay. So it is disingenuous for the patent owner to come in here
`and tell you, and represent to you, the Board, that this is a new argument.

`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`If it was a new argument, then how did they respond to it before our
`reply?
`
`They did. They had an opportunity to. This is not the only
`example. We provided a number of those. But it is disingenuous for
`them to represent to you that this is a new argument.
`
`Now, what we'll say -- what I'll put forward is that -- is that the
`patent owner's argument -- and I'm going to put forward -- here's our
`Figure 2. And what I'd -- what I'd like to do -- this is Figure 2 of Archer.
`
`I'm just going to draw in that when we use that narrower
`construction of the patent owner, we identified -- specifically, we
`identified our tandem access controller here.
`
`And I'll just draw it out here. Here's our tandem access controller
`that we identified in the petition in one of the alternative rounds. Now,
`there were other -- there were descriptions based on the construction
`switching facility. But that was certainly one that we put it in.
`
`Now, the patent owner's argument in its response is this: It alleges
`that Archer does not disclose the secret sauce, that handling the calls at
`the tandem level. And it's reason is simple. It says that Archer here, at
`the converter, can only receive analog signals. That's its position. And
`based on that, it's saying, okay, if it only receives analog signals, then it
`can't be the secret sauce, because secret sauce was call processing in
`digital form. Call processing in digital form.
`
`Well, I already know that my call processing here is certainly in
`digital form. So the question is, is my call processing in Archer, can it be
`ever -- can it ever be in digital form under any embodiments?

`Case IPR2016-01262 (Patent 7,764,777 B2)
`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`And patent owner's position is absolutely not. It can never. It
`
`must only be in analog form. That's how they're interpreting Archer.
`
`Now, the patent owner -- the patent owner is wrong. And I'm
`going to show you a few ways why.
`
`First off, in Archer, a disclosure of Archer, it has a number of
`different embodiments. Well, let's just talk about one of those
`embodiments here.
`
`This is column 5 of Archer. And here we are looking at column 5,
`line 10 to 11. That's where I want you to focus, Your Honors. We are
`going to focus right here.
`
`And it says: Circuit switch network 118 can be either an analog
`network, a digital network, or a combination of both.
`
`So Archer contemplates that its circuit switch network could be
`entirely digital. And in that embodiment, if we look here again, in this
`embodiment, if that circuit switch network is entirely digital, then my call
`processing is not entirely digital. It's maintained at the tandem level.
`
`A person of ordinary skill in the art would understand that. So that
`secret sauce is right here. That secret sauce is right there in Archer.
`
`JUDGE PARVIS: So petitioner -- what you're arguing is that the -
`- there's two -- the tandem access controller, the petitioner pointed to the
`database 138 and the server processor 128, correct?
`
`MR. TYSON: In certain embodiments, yes. Yes, Your Honor.
`
`JUDGE PARVIS: And then the converter 126, it's petitioner's
`position that that's part of the tandem access controller? Yes, it may be --

`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`afternoon, we're just using patent owner's construction.
`
`We're saying that that call processing, this can be part of the TAC.
`That gateway, if that converter, which Archer also talks about as a
`gateway, could be a tandem switch, it's a switch that can be
`interconnected to edge switches.
`
`It also could be a gateway. It is a -- any point in the switching
`fabric of converging networks is explicitly one of the switching facilities.
`
`And so if you read our petition, because switching facility was a
`term introduced in the claims, we identified a number of different
`interpretations, Your Honor. This was one of them. And there's another
`interpretation where the server processor and the database could also be
`the call processing system.
`
`So this is -- this is using the patent owner's construction.
`
`JUDGE PARVIS: This is page 50 of your petition --
`
`MR. TYSON: It's page 33. I can actually identify all the pages,
`Your Honor, before we do this. It's in our responsive listing. And if you
`-- I could either do it at rebuttal --
`
`JUDGE PARVIS: The responsive listing is fine.
`
`MR. TYSON: Okay. Thank you.
`
`Now, what I was just starting to say is that the patent owner does
`not -- it totally ignores this. It totally ignores this limitation in the claims.
`And instead, what it does, is it puts out this very, very bold statement in
`its patent owner response.
`
`And it says -- this is right here. This is the patent owner response
`at page 38. And I just want to focus right on this first sentence here.

`Case IPR2016-01263 (Patent 8,155,298 B2)
`
`And this is the statement of the patent. So it doesn't rebut Archer's digital
`embodiments. It doesn't -- it doesn't address it at all.
`
`So what it does say is: Prior to the date of invention of the
`challenged patent, a person of ordinary skill in the art would understand
`that any prior art disclosing an edge device external to the PSTN must
`access the PSTN through an edge switch first, not a tandem switch.
`
`Now, I had to read that probably three or four times to even figure
`out what it was saying. And the reason it's so difficult is because it's
`highly circular. Okay.
`
`What this is saying is that an edge device is connected to an edge
`switch. And an edge switch -- and an edge switch is a switch that's
`connected to an edge device.
`
`So an edge device is a device connected to an edge switch. And an
`edge switch is a switch connected to an edge device. And based on that
`definition, it's very confusing. And they do that. You'll hear that. They
`use these terms very loosely.
`
`And it's very important. Because what this is actually saying --
`what this statement is actually saying that in May 2000 -- because that is
`the time of the invention -- May 4th -- and, you know, we're not saying
`that that's the time of the invention, but for purposes of this hearing, I'm
`going to state that that's the time of the invention. May 4, 2000.
`
`What it's saying is: Any device that wants to connect to a switch
`in the PSTN can only connect to a Class 5 switch. That is what this says.
`
` Any device that wants to connect into the PSTN, the only way
`they can do that is through a Class 5 switch. That's what that says.
