`JUDGE JEFFERSON: Good afternoon. This is a trial hearing for
`two inter-parties reviews, IPR 2019-01567, involving U.S. Patent Number
`7,292,870, and IPR 2019-1568, involving U.S. Patent Number 7,894,837.
`The petitioner is Google -- the petitioners are, sorry, Google LLC,
`LG Electronics, Inc., and LG Electronics U.S.A., Inc. The patent owner is
`Zipit Wireless, Inc.
`I am Judge Jefferson, and with me are Judges Powell and Hamann. I
`want to, before I turn to Counsel for appearances, I want to ask if the court
`reporter can hear us, and if so far we are on the record with the court
`reporter.
`COURT REPORTER: Yes, I can hear you.
`JUDGE JEFFERSON: Thank you. Let the court reporter know if
`there's any issues with your audio or feed. Obviously you have experience
`with this, but please let us know and we'll pause the proceedings and get it
`straightened out.
`So I'll turn to welcome and thank you all for your flexibility,
`obviously, and conducting hearings by teleconferences is new to us. Maybe
`not new to some of the members of the parties that are here today. But we
`know this is a departure, and we appreciate your help in getting these
`hearings underway.

`
`So let's turn to the -- before I turn to the parties for appearances, let
`me give a little other housekeeping stuff.
`Obviously our primary concern is that you're heard and present and
`on the record for the case that you're making. If, any time during the
`proceedings, you encounter technical or other difficulties, that you feel
`undermines your ability to adequately represent your client or the
`information being presented, please just let us know immediately.
`You should have been given contact information from our team
`members to help you maintain your connection. Please use those if your,
`you know, your communications with us teleconference-wise is interrupted.
`Second, when not speaking, please mute yourself. I think it helps
`with background noise, as well as helps the court reporter get a clean
`recording of our proceeding.
`Please identify yourself when you speak. That helps the court
`reporter, obviously, but it also helps us and gives the screen a little time to
`adjust if you're going to become the video portion for everyone here.
`Fourth, I believe we have the entire record, including demonstratives
`that the parties have filed, and referring to them, obviously, refer to the
`exhibit numbers or names.
`Please speak clearly and explicitly by slide or page number. It helps
`the transcript. Also helps us follow along. You can give us a few seconds to
`catch up, but you can anticipate that we are doing so.

`Finally, our hearing's open to the public. I believe in our pretrial we
`talked a little bit about that, whether it's your own team members or others in
`the public that have requested lines, they have been given access.
`I'm not aware of any sealed or confidential information in this
`proceeding. Nonetheless, if you have some issue, please bring it to our
`attention.
`And now, at this time, I'll ask Counsel to introduce yourselves.
`Please let us also know who might be participating on your teams, either by
`audio or video. And we'll begin with Petitioner in that regard.
`MS. HUNT: Good afternoon, Your Honor. Thank you. My name is
`Elizabeth Hunt, with Wolf Greenfield & Sacks, representing Petitioners.
`With me are Anant Saraswat and Richard Giunta, also from Wolf
`Greenfield. I plan to present a portion of our arguments today and Mr.
`Saraswat plans to present a portion as well.
`JUDGE JEFFERSON: Thank you for that information. Helps with
`the court reporter as well. We'll turn to the Patent Owner. Please introduce
`yourselves, and as per the Petitioner's instructions, let us know who's
`participating with you, either online or on video.
`MR. RISLEY: Thank you, Your Honor. Good afternoon. This is
`Steve Risley for the Patent Owner, Zipit Wireless, Inc. And with me today,
`as well, participating by video is Cortney Alexander. And we, too, will be
`splitting up the argument into two parts.

`JUDGE JEFFERSON: Thank you. Let the parties know that
`certainly it's up to you, I'll let you decide how you split that up. I'll try to
`keep -- I will be keeping time.
`As you know from our pretrial order, each party has 75 minutes in
`total to present their arguments. Petitioner has the burden of showing
`unpatentability of the challenged claims, and will proceed first, followed by
`the Patent Owner.
`Petitioner and Patent Owner may both reserve rebuttal time, which,
`by that ordering, would mean the Patent Owner gets to go last.
`I'll repeat for clarity again -- transcript is important, it's useful to us, I
`know, to all of us, so please state the slide number, exhibit, or page number
`you're referring to.
`And although we will review written objections and motions as we're
`deliberating, and usually those are answered in our appearances, feel free to
`highlight during your presentation if any of those issues matter to your
`particular arguments that you're making before us today.
`I will be the timekeeper, the ultimate timekeeper. As I think I
`indicated before I'm not a stickler with that. I'm certainly not interested in
`going over by a lot, but if there's additional information that can be brought
`out during our discussion, I certainly will allow some time to let it happen.

`
`But I will be keeping time. I encourage you and your partners to
`keep time as well, and I will let you know at the end of each portion of our
`presentation when we will -- how much time you have left.
`And importantly enough, this is not a marathon. Whether it's my
`fellow judges or you guys, we will take a break, a five-minute break. We're
`not trying to keep you separated -- to your seats.
`I think we're all working in interesting environments, as you can see
`from our own backdrops here, so if we have interruptions from little ones,
`and maybe that's an indication on my side, or otherwise, I will -- may take a
`suitable break.
`But I think we'll try to take a five-minute break, as appropriate, to let
`the parties stretch their legs and straighten things out, and get back on the
`record as soon as possible, because, again, it's not a marathon, but we're not
`trying to be here all day.
`And with that in mind, I think I've covered all of the important
`things. So again, if technical difficulties present themselves, please know
`you will all be given time, and we'll get through it.
`I'm going to also tell you now and repeat at the end, please stay on
`the line afterwards in case the court reporter has spellings or issues or
`portions they did not get. They might want to ask you some questions and
`we'd appreciate you sticking around.

`Oh, and the last portion, of course, if you are going on break, I know
`sometimes you're chatting with your team, maybe they are remotely. Please
`mute yourselves.
`I don't want any inadvertent conversations to be shared with outside
`groups here when we're taking breaks. It's a little hard to take them
`virtually.
`So with that in mind, Petitioner, you start, and you will -- would you
`like to reserve time? And then once you tell me that, you certainly can begin
`when you're ready.
`MS. HUNT: Yes, thank you, Your Honor. Again, Elizabeth Hunt
`for the Petitioners. We are hoping to reserve 15 minutes for rebuttal.
`JUDGE JEFFERSON: Thank you. Noted. And you may begin,
`again, when you are ready.
`MS. HUNT: All right. Thank you. I know Your Honors have been
`familiar with the Zipit patents, so I will start on Slide 5 of our
`demonstratives.
`And on Slides 5 and 6, we've summarized the petition's grounds and
`references for the two patents, and we plan today to discuss just the issues
`that are disputed.
`I plan to cover the challenged independent claims, including
`addressing secondary considerations, and then Mr. Saraswat will address the
`one dependent claim in each patent that's separately disputed.

`
`
`
`Now, the independent claims are challenged under two grounds
`each. A combination based on Van Dok, and a combination based on Zaner.
`Slide 7. There are only a few disputed limitations in the independent
`claims. Each patent has a limitation involving a data entry device, and
`graphical symbols, like emoticons. And then the '870 patent also has
`disputed limitations about connection loss.
`I'll start with the '837 Claim 11, which has only one disputed
`limitation. And I'll start with the Van Dok-based ground, where there's only
`one disputed issue, and that's whether Van Dok uses a data entry device of a
`handheld instant messaging terminal.
`Going to Slide 9, this is a claim construction issue, and it's
`dispositive. Zipit's only argument against how this ground meets the '837
`Claim 11 is that Van Dok doesn't say the data entry device of its handheld
`terminal is integrated in the housing of the handheld.
`But Zipit's claim construction just inserts the words, integrated into
`the -- sorry, integrated into the housing, into the claim language. And that's
`not a construction. It's not construing any term in the claim. It's just adding
`words, which is blatantly importing limitations.
`Your Honors were correct to reject this at institution, and Zipit gives
`you no supportable reason to reconsider now.
`Slide 10. As our reply pointed out, Zipit made the affirmative choice
`not to limit Claim 11 to an integrated data entry device. They chose to
`
`
`
`9
`
`
`
`IPR2019-01567 (Patent 7,292,870 B2)
`IPR2019-01568 (Patent 7,894,837)
`
`
`
`include that limitation in the other independent claim, Claim 1. And they
`chose not to put it in Claim 11.
`And the federal circuit said, in Kara Tech, this means the latter
`independent claim is not limited the way the first one is, and it would be
`error to import the limitation. And Zipit did not even try to respond to this
`point that we made in our reply, so this point is unrebutted.
`Slide 11. The only argument Zipit made for Your Honors to
`reconsider their claim construction is, they allege that the prosecution history
`disclaimed non-integrated data entry devices.
`But as our expert explained, Zipit mischaracterizes the prosecution's
`statements. They allege that in distinguishing Rucinski, the Applicant said
`the data entry device has to be integrated in the handheld's housing.
`But the applicant never talked about the data entry device, which, in
`this case, is a keyboard. That is undisputed, that Rucinski already had an
`integrated keyboard. You can see that in Rucinski's Figure 3. And Zipit's
`expert agreed.
`So contrary to Zipit's suggestion, an integrated keyboard was not part
`of their basis for distinguishing Rucinski. What Rucinski did that was
`different was Rucinski had a separate computer do some of the IM protocol
`processing.

`
`
`
`So Zipit distinguished Rucinski by saying that this IM protocol stuff
`had to be done in the handheld, and that's completely unrelated to the
`keyboard, and it's the only aspect discussed in the '837 file history.
`Slide 12. It's the same in the '870 file history. The distinguishing
`arguments were all about the protocol processing. Rucinski did that in a
`separate computer, and Zipit distinguished by saying the protocol processing
`had to be done in the handheld.
`Now, Zipit points to some passing mentions of data entry, where the
`applicant was saying that unlike Rucinski, Zipit's system does the protocol
`processing in the same handheld that supports the data entry and display
`functions.
`That's not saying the keyboard is integrating in the housing. Again,
`Rucinski already had an integrated keyboard, so there was no reason the
`prosecution would be talking about that.
`The applicant's distinction with Rucinski was that all the software
`processing happens in the handheld, so you don't need a whole separate
`computer to be involved.
`And you see that here on Slide 12, and you'll see the same when
`Zipit shows you the snippet they put on their Slide 8. The applicant refers to
`the, quote, processing, identified in the claim.
`And that software processing includes protocol processing, wireless
`access, and display and data entry functions, which, if you look at our Slide
`
`
`
`11
`
`
`
`IPR2019-01567 (Patent 7,292,870 B2)
`IPR2019-01568 (Patent 7,894,837)
`
`
`
`13, both experts testified that data entry always involves software drivers in
`the handheld's processor that receive and interpret signals from other
`devices, like keyboards.
`So the data entry software function is in the housing, regardless of
`whether the keyboard is integrated or connected to those functions by a wire.
`That just doesn't matter, and it didn't matter in prosecution. The keyboard
`wasn't a distinguishing feature.
`Again, Rucinski had the same keyboard that Zipit does. The remarks
`in the file history all about software processing functions, and not about
`what peripherals those functions get signals from.
`So Dr. Abowd explained that a POSA wouldn't see any disavowal of
`nonintegrated keyboards here, let alone a clear and unambiguous disavowal
`as the law requires for disclaimer.
`So Zipit's construction requiring an integrated data-entry device is
`entirely unsupported. If Your Honors reject it as you did at institution, that's
`determinative for the '837 Claim 11 on the Van Dok ground.
`The only other issue affecting that ground is secondary
`considerations, and I'll discuss those at the end. When we get there, one
`thing to remember is that Zipit's only patentability argument on this ground
`was claim construction.

`
`
`
`Zipit didn't dispute the petition's combination or motivation to
`combine, and they don't cite any cases suggesting that secondary
`considerations would be relevant to claim construction.
`Slide 14. Briefly, also, before moving on from the '837 claim, even
`if Zipit's incorrect claim construction were adopted, both experts have
`testified that the term handheld device tells the POSA that the handheld data
`entry device is integrated in its housing.
`And Van Dok says that all the techniques it discloses can be
`practiced in a handheld device configuration. So a POSA would've
`understood, that configuration meets even Zipit's construction.
`Again, this testimony from both experts is unrebutted. The only
`response in Zipit's sur-reply, Page 4, is attorney argument citing their own
`patent as saying that a handheld could use a detachable keyboard.
`But Dr. Abowd addressed that in his reply declaration, Paragraph 10,
`cited in our '837 reply, Page 5. He explained that the reference Zipit's patent
`cites describes detachable keyboards only as additional options where the
`handhelds also have integrated data entry devices.
`It's completely consistent with both experts' testimony that handheld
`device, which is what Van Dok discloses, means its data entry device is
`integrated.

`
`IPR2019-01567 (Patent 7,292,870 B2)
`IPR2019-01568 (Patent 7,894,837)
`
`
`
`
`And Your Honors, unless there are questions on '837 Claim 11 with
`Van Dok, I will look at the '870 patent next, staying with the Van Dok
`grounds.
`JUDGE JEFFERSON: This is Judge Jefferson. Just to be clear, is
`Zipit's argument directed only to the integration, the sort of integral nature of
`the keyboard not being attached, the input device not being attached?
`As I understand it, the parties have no dispute or discussion over
`whether, you know, as in the Rucinski reference, some of the -- what I'll call
`software or driver information is done on or off board.
`That's not a dispute at all, because the claims, as I read them, are
`directed toward the inputting of data and the quote-unquote integrated nature
`of whether that part is somehow combined in a single housing of some sort.
`Right?

`17
`18
`19
`20
`21
`22
`
`There's no dispute about the other sort of software-based functions
`that you were talking about with Rucinski.
`MS. HUNT: Yes, as I understand Your Honor's question, there's no
`dispute that the IM protocol processing, wireless access, all the software
`processing functions, are happening within the handheld in the petition's
`combination.
`JUDGE JEFFERSON: Okay. Thank you.
`MS. HUNT: All right. So Slide 16. Moving to the '870 Claim 20,
`and staying with the Van Dok grounds, the '870 Claim 20 has a similar
`
`
`
`14
`
`
`
`IPR2019-01567 (Patent 7,292,870 B2)
`IPR2019-01568 (Patent 7,894,837)
`
`
`
`limitation, reciting a data entry device of a handheld terminal. And Zipit
`argues the same integrated data entry device construction here, as well. That
`fails for all the reasons we just discussed.
`Now, for this claim, there's one additional issue about the entering
`graphical symbols limitation in blue on this slide, before we get to the other
`highlighted limitations.
`On Slide 17, Van Dok discloses that the user types the sequence
`colon-parenthesis to produce the graphical smiley by an automatic
`conversion.
`And Zipit argues that's not entering a graphical symbol. Your
`Honors correctly rejected that argument at institution, where you said it
`improperly requires limitations from the specification's embodiments to be
`read into the claim.
`Van Dok clearly discloses a graphical emoticon being entered into an
`instant message by using a keyboard, which is a data entry device. So Van
`Dok meets the claim, plain language.
`Slide 18. Zipit's own patents describes that same technique as a way
`graphical emoticons can be, quote, entered, which is exactly the claim
`language that Zipit now says somehow excludes this.
`The spec says, graphical emoticons, quote, can be entered by
`depressing their standard key sequence, unquote, just like Van Dok does.
`And both experts agree, this is what the spec discloses.

`14
`15
`16
`17
`18
`19
`20
`21
`
`
`
`So contrary to Zipit's sur-reply, the spec doesn't say that this entry
`method is less preferred than using emoticon keys. The spec says, in
`Columns 19 to 20, that the invention includes both, because there are a lot of
`emotions to support. So Zipit's argument against Van Dok is inconsistent
`with their own spec.
`Slide 19. We pointed out this specification embodiment in the
`petition, and Zipit's POR completely ignored it. They never argued that the
`claim doesn't cover this embodiment.
`After we pointed out this waiver in our reply, their sur-reply then
`belatedly argued that you should interpret Claim 20 to exclude the
`embodiment in their own spec.
`That's an improper new argument they should've raised in their POR,
`and instead they waived it, so Your Honors shouldn't consider it. But even if
`you do consider it, it's baseless.
`Slide 20. The claim says, entering graphical symbols. And the spec
`says, graphical symbols can be entered by typing their text sequence. It
`couldn't be clearer that the claim language covers what the spec says that
`very language covers.
`Zipit's new attorney argument, that the claim was amended in
`prosecution to the symbol displayed is the same symbol that was entered,
`they say that can't encompass what their spec describes, but that's not true.

`
`The claim talks about entering graphical symbols to form instant
`messages. So the entering in the claim is about what's going into the instant
`message.
`And in both Zipit's spec and in Van Dok, that's the graphical symbol.
`The claim doesn't limit what buttons are pressed on the keyboard to create
`that graphical symbol that's entered in the message.
`And their own spec says that the text sequence can be what's pressed.
`In fact, if it follows Zipit's new logic that you have to display exactly the
`same data that came through the keyboard. It wouldn't read on any
`embodiment, even the ones that have a dedicated emoticon key.
`Zipit's expert testified that the data from the keyboard is always
`different from what gets displayed, because a keyboard just generates a
`coordinate code that some software always has to interpret into some
`character or symbol for display.
`So Zipit's argument for excluding their own embodiment, first, its
`attorney argument is unsupported by any expert testimony on what a POSA
`would've understood.
`And second, it just makes no sense. It's inconsistent with the plain
`claim language, the same language in the spec, and their expert's testimony
`about how keyboards work.
`Slide 21. Those are their only arguments for the entering limitation.
`So if Your Honors agree with us on entering and on construction of data

`
`entry device, then Van Dok meets this blue limitation, 20A. If there aren't
`questions on that, I'll move on to 20F and 20G.
`JUDGE JEFFERSON: Continue.
`MS. HUNT: All right. So Slide 22. Limitation 20F says, displaying
`conversation histories for active conversations terminated by a loss of a
`network connection. The petition showed that McCarthy teaches this
`limitation, and then combined McCarthy with Van Dok and with Zaner.
`McCarthy discusses an IM user's status going passive, which means
`that they temporarily can't send messages. And McCarthy shows that the
`conversation histories continue to be displayed during passive status.
`And McCarthy says, one way this can happen is when there's a loss
`of connection. That's the top quote here on Slide 22. Zipit doesn't dispute
`this. What Zipit argues is that the connection McCarthy says is lost is not a
`network connection.
`But McCarthy is explicit. The interaction status, which can be
`passive or active, can reflect, quote, a current network connection status,
`because it indicates whether the user is connected, quote, via a network
`connection, end quote.
`So there's two ways McCarthy says you can go passive, in the top
`quote on Slide 22. You can deliberately choose to switch to passive status.
`And you can also be forced passive because you lost your connection.
`Either way, your conversation histories are still displayed.

`
`Now, Zipit argues that because the client connects specifically to a
`thread server over the network, then McCarthy must be talking about losing
`the server connection, rather than the network connection.
`That's all a red herring. Everyone agrees that a server connection
`requires a network connection. The client connects to the server through the
`network. So when the client loses its network connection, of course it loses
`its connection to the server.
`It doesn't matter if you could also lose a server connection some
`other way, like if the server somehow goes down. McCarthy doesn't talk
`about that problem. It doesn't mention ways you could lose your server
`connection without losing your network connection.
`What McCarthy talks about is dealing with problems with the client's
`connection to the network. You can see on --
`JUDGE HAMANN: Counsel? This is Judge Hamann. Just a quick
`question. How would you characterize what a server connection is, versus
`what a network connection is?
`MS. HUNT: So a client's connection to a network allows the client
`to communicate with many devices that may be accessible over the network.
`And then in McCarthy, in one embodiment, there is a server hosting the
`instant messaging that the client will communicate with over the network.
`JUDGE HAMANN: Okay, so I'm not sure I fully appreciate the
`distinction being drawn. I think I do, but I'm just trying, for the record, to
`
`
`
`19
`
`
`
`IPR2019-01567 (Patent 7,292,870 B2)
`IPR2019-01568 (Patent 7,894,837)
`
`
`
`have a better understanding of Petitioner's position as to the difference
`between server connection and a network connection, the context of this
`reference.
`MS. HUNT: To be honest, Your Honor, it's a distinction that Zipit is
`drawing, and not Petitioners. So McCarthy is talking about a network
`connection.
`Over and over and over, McCarthy talks about a client being
`connected to devices via a network connection. And there's a server that it
`can receive communications from, over the network.
`But McCarthy -- what McCarthy discusses explicitly is network
`connection problems, and the client having to be connected via network
`connection, and then a loss of connection causing passive status, where they
`can't receive communications.
`So if you look, for example, on Slide 24, McCarthy's introduction
`says that its goal is to maintain communications through problems with
`intermittent connectivity in client devices, like portable Wi-Fi devices.
`And Dr. Abowd explained, this is talking about the client's network
`connection. Zipit didn't dispute that. So Zipit makes this allegation that
`network connection loss is not McCarthy's concern, and it's clearly wrong.
`Addressing client devices -- sorry, go ahead, Your Honor.
`JUDGE HAMANN: No, no, I didn't mean to cut you off. If you
`want to finish that point, and then I'll ask my question right after that.

`MS. HUNT: I was just saying that addressing clients' devices
`network connection problems is exactly McCarthy's concern, as it explicitly
`states right here.
`JUDGE HAMANN: Okay. Well, then, in McCarthy, is there a
`teaching that the point of attachment to the network is the server? Or is it a
`different point of attachment to the network from the device?
`MS. HUNT: The client device -- so, for example, in this quote from
`McCarthy at Column 2 on our Slide 24, it talks about devices having
`connectivity, for example, Wi-Fi-enabled laptops or cellular telephones or
`portable computing devices.
`So a POSA understands, in reading that, that a client's connection is
`to -- for example, a Wi-Fi connection is going to be to a Wi-Fi access point.
`Right? Not to the specific server that is sending, you know, particular
`instant messaging conversations, facilitating those conversations going
`between devices. Right?
`The server will also need to be connected to the network in order for
`them to communicate with each other. But what McCarthy doesn't talk
`about is, well, what if the server loses its connection so the client can't hear
`from it anymore?
`What McCarthy talks about is, we're trying to deal with client
`devices that have problems with connectivity to the network, because they're
`

`

`
`
`
`Wi-Fi, they're portable. POSAs understood that these types of devices,
`they're moving around. It's hard for them to maintain a stable connection.
`And then McCarthy says, so it would be beneficial to have this
`messaging system that doesn't, in the user experience, doesn't disrupt the
`messaging experience while the user's client device is experiencing
`connectivity problems. Another --
`JUDGE HAMANN: Thank you.
`MS. HUNT: Yes, thank you, Your Honor.
`JUDGE JEFFERSON: Counsel, this is Judge Jefferson.
`MS. HUNT: Yes.
`JUDGE JEFFERSON: Let me ask a piggyback off my colleague's
`question. Patent Owner seems to be saying that network connection in the
`'837 -- I'm sorry, in the '870, is directed specifically to, in the claims,
`network connection is connected specifically to a wireless or managing a
`wireless network kind of access.
`So it's a break in that particular kind of connection. Do you agree
`with that, that the claims themselves are directed solely to that?
`MS. HUNT: So the claim recites a connection to -- a wireless
`connection. In the petition's combination, the network connection that's
`being made, based on Sinivaara, is a wireless access point connection to a
`local network. Right?

`
`So that limitation was established, that it was met, and Zipit didn't
`dispute that, through their reliance on Sinivaara. McCarthy is completely
`consistent with that, in that McCarthy talks about portable, for example, Wi-
`Fi client devices. Those would be connecting to the same sort of local
`network.
`And then McCarthy says that these client devices' network
`connection can be lost. So in the combination, that's the network connection
`that's being lost.
`JUDGE JEFFERSON: Okay. Thank you.
`MS. HUNT: I want to mention -- this was also mentioned in our
`papers, for example, in our reply at Page 8. McCarthy also says at Column
`9, Lines 22 through 30, also there, that its purpose is maintaining
`communications during passive status when a client, quote, is not currently
`connected to other computing devices, end quote.
`So it's saying that client is not connected to any other devices. And
`that means the network connection loss. That client lost its connection to the
`network which all the devices are on.
`If
