`
` EXAMINATION BY COUNSEL FOR PATENT OWNER
`
`BY MR. GANNON:
`
` Q Good morning, Mr. Rho.
`
` A Good morning.
`
` Q Nice to see you again.
`
` A Good to see you as well.
`
` Q Could you state your name for the record,
`
`please.
`
` A Yes. My name is David Rho, R-H-O.
`
` Q And your address?
`
` A My current address is 60 Demott Street,
`
`D-E-M-O-T-T, in Tenafly, New Jersey.
`
`T-E-N-A-F-L-Y.
`
` Q Okay. And you understand you're under
`
`oath this morning, correct?
`
` A I do.
`
` Q And that means you're sworn to tell the

`
`truth just as if you were testifying before a
`
`jury, correct?
`
` A I understand that, yes.
`
` Q Okay. Is there anything that would
`
`prevent you from providing truthful and accurate
`
`testimony today?
`
` A Not that I'm aware of, no.
`
` Q Okay. You're not on any medication that
`
`would prevent you from doing so?
`
` A No, I am not.
`
` Q I know you've been deposed before. We
`
`met on some other TT patents, so I know you're
`
`familiar with the proceedings. But if you don't
`
`understand any of my questions, please just let me
`
`know and I'll try to rephrase them. Okay?
`
` A Okay.
`
` Q Is it fair for me to assume that if I ask
`
`you a question and you provide an answer, that
`
`you've understood my question?
`
` A Yes, but I would, of course, reserve the
`
`right to change my answer if I realize that I
`
`didn't understand the question.

`
` Q Okay. Fine. And we'll be -- we can take
`
`a break whenever you'd like. Just let me know.
`
` A Okay.
`
` Q I just ask that if a question is pending,
`
`that you provide an answer to the question before
`
`we break.
`
` A Yes, of course.
`
` Q And you understand that at the break,
`
`you're not permitted to discuss your testimony
`
`with counsel, correct?
`
` A Yes. I've been instructed as such.
`
` Q Did you prepare for the deposition today?
`
` A Yes, I did.
`
` Q And what did you do to prepare?
`
` A I spoke with counsel. I reviewed
`
`documents. And I think I'm not allowed to dig
`
`into any of the details, but that's pretty much
`
`what we did.
`
` Q About how long did you take preparing for
`
`the deposition today?
`
` A Less than a day.
`
` Q Was that yesterday?

`
` A That was yesterday.
`
` Q And who did you meet with to prepare for
`
`the deposition today?
`
` A I met with Rich and with Lori.
`
` Q Okay. Did you review any documents?
`
` A Yes, we did.
`
` Q What documents did you review?
`
` A I reviewed my declaration. I reviewed
`
`the patent. I reviewed most of the listed
`
`materials in my -- for my declaration, and I
`
`reviewed the petition and the institution -- the
`
`institution decision.
`
` Q Okay. You said that you --
`
` A Oh. Also, I reviewed my transcripts from
`
`my two previous depositions.
`
` Q What two previous depositions was that?
`
` A So that was the -- the one that we did a
`
`couple of months ago, or a month or so ago, and
`
`then for the TD.
`
` Q Okay. And you said you reviewed some of
`
`the listed materials; is that right?
`
` A Yes.

`
` Q But not all the listed materials?
`
` A Not necessarily all, no.
`
` Q Why is that? Why did you pick some but
`
`not others?
`
` A It was -- I think it was a practical
`
`matter. There were items such as the case file.
`
`We didn't review that.
`
` Q So let me hand you what's been marked as
`
`Exhibit 1004 in the '055 CBM.
`
` So, Mr. Rho, I've handed you what's been
`
`marked as Exhibit 1004. Do you recognize it?
`
` A Yes, I do.
`
` Q And what is it?
`
` A This is my declaration for the '055
`
`patent.
`
` Q And did you prepare this exhibit?
`
` A This exhibit was prepared in close
`
`collaboration with counsel.
`
` Q And what does that mean?
`
` A That means that we worked together. We
`
`crafted words together. So some of the words are
`
`mine; some of the words may have been crafted by

`
`the attorneys, in large part, to ensure that it
`
`met legal standards. But the substantive content
`
`of the document was prepared -- or at least was
`
`prepared with input from me or was actually
`
`crafted by myself.
`
` Q You said in your previous answer that
`
`some of the words are yours; is that right?
`
` A Yes.
`
` Q Do you know which ones are yours?
`
` A This was a long collaboration, and I
`
`couldn't point out exactly which words are mine
`
`and which words were necessarily crafted by the
`
`attorneys. But, regardless, I did review the
`
`entire document --
`
` Q Okay.
`
` A -- and read it front to back several
`
`times.
`
` Q Okay. That was going to be my next
`
`question, which words were selected by counsel?
`
`Do you know?
`
` A I wouldn't be able --

`
` You don't need to answer that question.
`
`BY MR. GANNON:
`
` Q Are you going to follow that instruction?
`
` A I'll follow my attorney's advice, yes.
`
` Q Okay. This particular declaration
`
`references something called TSE, correct? And in
`
`particular, I'm looking at page 9 of your
`
`declaration.
`
` A The first word on that page,
`
`paragraph 28, is TSE. So yes.
`
` Q Okay. And in this -- this is section 4
`
`of your declaration, correct?
`
` A I apologize. Once again -- I think this
`
`happened the last time. The formatting was --
`
`there was an error in the formatting. So it goes
`
`from section 1 to section 2, back to section 1, to
`
`section 3. So this is -- should actually be
`
`section 5, but it's labeled as section 4.
`
` Q Okay. So in paragraphs 28 through 36,
`
`there appears to be a discussion of your
`
`understanding of how TSE operates. Is that a fair
`
`statement?

`Page 11 of 71
`
`
`
` A I apologize. I'm just trying to get this
`
`Page 12
`
`to stop buzzing.
`
` Q No problem.
`
` A I'm sorry. Could you repeat the
`
`question?
`
` Q Sure. Paragraphs 28 through 36 of your
`
`declaration appear to be a description of your
`
`understanding of how TSE operates. Is that a fair
`
`statement?
`
` A Well, the section is also -- this
`
`subsection A is also listed as overview. So, yes,
`
`that would be a fair assessment.
`
` Q That's an overview of how you believe TSE
`
`operates, right?
`
` MR. BEMBEN: Objection. Mischaracterizes
`
`testimony.
`
` THE WITNESS: I believe this is more of a
`
`review of the TSE document and what it describes.
`
`BY MR. GANNON:
`
` Q Right. And paragraphs 28 through 36
`
`include a description of your understanding of
`
`TSE. Is that a fair statement?

`

`
` THE WITNESS: Could you put a little bit
`
`more context around that, because it's pretty
`
`broad. You just asked a very broad question.
`
`BY MR. GANNON:
`
` Q I'm just trying to -- just a general
`
`question. In paragraphs 28 through 36 --
`
` A Yes.
`
` Q -- those paragraphs deal with your
`
`understanding of how TSE operates. Is that a fair
`
`statement?
`
` MR. BEMBEN: Objection. Foundation.
`
`Asked and answered.
`
` THE WITNESS: So if you're talking about
`
`TSE as a whole, so floor versus electronic -- I
`
`mean, that's why I'm -- you're saying you're
`
`asking a general question, but you're asking a
`
`very, very broad question. So does it give me a
`
`full understanding as to how TSE as a whole works?
`
`No.

`

`
` Q Okay. Well, what was the purpose of this
`
`overview section, then? When I say overview
`
`section, I'm referring to paragraphs 28 through
`
`36, just generally.
`
` A So this was to really cover the trading
`
`system, this futures and options purchase system
`
`that was described in the TSE document that I did
`
`review.
`
` Q Okay.
`
` A So this was to summarize my findings on
`
`that and -- the pertinent findings because the
`
`document itself is quite large and covers areas
`
`that are outside of the scope of the patent.
`
` Q Okay. Let me show you what's been marked
`
`as Exhibit 1008 in the '055 CBM. And, Mr. Rho, I
`
`just wanted to ask you a general question, and
`
`feel free to look at it, but do you recognize
`
`Exhibit 1008?
`
` A Yes. This is the TSE manual for the
`
`futures options purchasing system, trading
`
`terminal operation guide.

`of your overview section of TSE in your
`
`declaration that we were just referring to?
`
` A Yes, it did.
`
` Q Okay. So let's go to your declaration.
`
`I just have some questions about -- pertaining to
`
`this overview section where you're describing TSE.
`
`And, in particular, I have a question with respect
`
`to paragraph 32. And in the middle of
`
`paragraph 32 -- about the middle of paragraph 32,
`
`you say the trader sets the price display method
`
`by selecting a radio button. Do you see that?
`
` A Yes.
`
` Q And the radio button that you're
`
`referring to there enables you to switch between
`
`compressed and uncompressed; is that right?
`
` A That's my understanding, yes.
`
` Q Okay. So let me just ask you this: In
`
`TSE, how does a user switch from compressed to
`
`uncompressed and vice versa?
`
` A Well, I'll read you from the TSE
`
`document, page 69: Setting method, selecting the

`
`setting by the attached information type by
`
`operating send, enter.
`
` Q Does this part -- now you're referring to
`
`Exhibit 1008, correct, page 69?
`
` A Page 69 of Exhibit 1008. That's correct.
`
` Q Does that show the radio button, that
`
`page?
`
` A It shows several radio buttons on this
`
`page.
`
` Q Can you describe them? You're looking at
`
`the figure on page 69?
`
` A I'm looking at the figure 6-4 on page 69,
`
`yes.

`

`
`Page 16 of 71
`
`
`
`Page 17
`
` Q What does that figure show?
`
` A It shows a dialog box with a number of
`
`radio buttons, some of which appear to be
`
`selected, some of which appear to be nonselected.
`
`And then, in the lower right-hand corner, it
`
`appears to have two buttons that -- one is likely
`
`send and the other is likely cancel. It's a
`
`little difficult to read this figure.
`
` Q The send and cancel, where are those?
`
` A That would be in the lower right-hand
`
`corner. That's a typical GUI -- that would be
`
`what you would typically do in a GUI, is you would
`
`put them towards the bottom or on the right-hand
`
`side.
`
` Q Is that written in Japanese?
`
` A It's obscured, so I wouldn't be able to
`
`tell you what language it's in. It is likely that
`
`it is in Japanese.
`
` Q Do you read Japanese?
`
` A No, I do not.

`Page 17 of 71
`
`
`
`Page 18
`
`lower right-hand corner are labeled?
`
` A How do I know? That's general
`
`convention. That's general convention for GUIs is
`
`that you have the ability to tell the system that
`
`you would like to accept your changes and then you
`
`also give the user an opportunity to cancel any
`
`changes that you put in place.
`
` Q In this figure on page 69, can you
`
`actually identify the cancel button?
`
` A No, I cannot.
`
` Q What was the other button that you
`
`referred to in the lower right-hand corner?
`
` A Again, I refer back to the text above,
`
`which calls it send, enter.
`
` Q Can you identify the send button on
`
`page 69?
`
` A No, I cannot.
`
` Q Okay. Which radio button sets the screen
`
`for compressed or uncompressed in the figure shown
`
`on page 69?
`
` A I can't be sure.

`

`
`screens, one uncompressed and one compressed. Is
`
`that a fair statement?
`
` A Well, one is labeled non-compressed and
`
`the other is labeled compressed.
`
` Q Okay. Is non-compressed the same as
`
`uncompressed? I just want to get the terminology
`
`right. Because in this case, I've heard it
`
`referred to as uncompressed as well.
`
` A Uncompressed and non-compressed are
`
`effectively the same thing, yes.
`
` Q Okay. What would you prefer -- what
`
`language would you prefer to use, and I'll try to
`
`use it, just to be consistent, uncompressed or
`
`non-compressed?
`
` A I have no real -- I have no real -- no
`
`real preference.
`
` Q Okay. And then paragraph 33 below, you
`
`talk about a board screen, and you refer to a

`
`
` A A board screen that does not scroll is

`
`referring to?
`
` Q Right.
`
` A Okay.
`
` Q So the basic board screen -- when you're
`
`in the basic board screen, there's no scroll,
`
`right?
`
` MR. BEMBEN: Objection. Foundation.
`
` THE WITNESS: Well, I'll refer to
`
`page 115 of the -- Exhibit 1008. The first
`
`bulleted paragraph: A board screen that does not
`
`scroll is called a basic board screen wherein the
`
`display of the board information is updated so
`
`that the board display center price is
`
`continuously displayed at the center part of the
`
`board.

`
` Q So in the basic board screen, there's no

`Page 20 of 71
`
`
`
`Page 21
`
` THE WITNESS: I'll again refer to the TSE
`
`document on page 110. It's description number 5,
`
`scroll buttons and home button. So the first one
`
`has an up arrow. Clicking this button with a
`
`mouse scrolls the prices upward one price at a
`
`time. A down arrow. Clicking this button with
`
`the mouse scrolls the prices downward one price at
`
`a time. And the H. Clicking this button with the
`
`mouse after the board information has been
`
`scrolled causes the screen to return to the basic
`
`board screen, with the board display center price
`
`at the center.
`
` So the screen itself is in a non -- when
`
`it's in basic board screen mode, it is not in a
`
`scrolling mode, but to say that it does not scroll
`
`or is not -- I guess you have to define what
`
`you're asking for when it says does not scroll.
`
`Is it incapable of scrolling? Is it capable of
`
`scrolling but isn't in a scrolling mode?
`
`What's -- what's the question?

`
`
`
`Page 21 of 71
`
`
`
`Page 22
`
`paragraph 33 --
`
` A Sure.
`
` Q -- where you say, in the middle of the
`
`paragraph, a board screen -- do you see where it
`
`says, in the middle, a board screen, quote, that
`
`does not scroll is called a basic board screen,
`
`unquote -- do you see that?
`
` A Yes.
`
` Q So in the basic board screen, there's no
`
`scrolling going on, correct?
`
` A When it's in basic board screen mode, it
`
`is not being manually scrolled.
`
` Q I just want to make sure we're talking
`
`about the same thing. So what you said here is
`
`accurate, a board screen that does not scroll is
`
`called a basic board screen. Is that accurate?
`
` A It's a quote from the TSE document.
`
`So -- you would have to make sure that -- overall,
`
`that would have to be placed in the context of the
`
`rest of the document, but, yes, that is accurate.
`

`Page 22 of 71
`
`
`
`proceeding, I refer to the board screen as having
`
`a basic board screen mode and a scrolling screen
`
`Page 23
`
`mode.
`
` Do you see that?
`
` A That is the last sentence in that
`
`paragraph, yes.
`
` Q Right. When you said -- when you say in
`
`that sentence, basic board screen mode and
`
`scrolling screen mode, what do you mean by the
`
`word "mode"? What does that mean?
`
` A Well, I'm not a dictionary, but
`
`essentially, those two -- those are two
`
`different -- I'm sorry, I hate using -- I know
`
`they say you're not supposed to use the word when
`
`describing something. So there are two different
`
`possible settings you can have the screen working
`
`in. So basic board screen mode is one way for the
`
`screen to be displayed and updated. And then
`
`scrolling screen mode is a different way to have
`
`the information updated and displayed.
`
` Q All right. So let's look at page 115 of
`
`the TSE document, Exhibit 1008. Are you at

`Page 23 of 71
`

`
` A The paragraph starts, In a basic board

`screen.
`
` Q All right. And then at -- well,
`
`actually, let me -- before I ask you that, let me
`
`go to paragraph 32 of your declaration. Are you
`

`
` A Yes, I'm at paragraph 32.
`
` Q You say, The trader can select from two
`
`price display methods, non-compressed or
`
`compressed method.
`
` Do you see that?
`
` A Yes.
`
` Q Are the compressed and non-compressed
`
`methods you refer to in paragraph 32, are those
`
`compressed and non-compressed modes?
`

`Page 24 of 71

`
` A When it's in non-compressed mode, it
`
`displays all of the prices that are available
`
`regardless of if there's a bid or an offer at that
`
`level. And then there's the compressed method
`
`which skips over any prices -- still in ascending
`
`order of prices, but it skips over any prices that
`
`do not have a bid or an offer available at that
`
`level.
`
` Q Okay. So let's talk about this
`
`uncompressed and compressed, because I have some
`
`questions about that. So on page 12 of your
`
`declaration, there's that figure at the top of the
`
`page which shows non-compressed and compressed,
`
`right?
`
` A Yes.
`
` Q And in the compressed screen, the center
`
`price is always positioned in the center of the

`
` So in what mode are we in? Are we in a
`
`scrolling screen mode or are we in the more -- the
`
`non-scrolling screen mode?
`
`BY MR. GANNON:
`
` Q Well, let me -- I guess let me ask you
`
`that just to clarify. On page 12 of your
`
`declaration, the figure on the right at the top of
`
`the page, is that -- what mode is that in?
`
` A That's in a compressed price display
`
`mode.
`
` Q And is that in a scrolling mode or a
`
`non-scrolling mode?
`
` A That is in a non-scrolling mode.
`
` Q How do you know that?
`
` A I'm going to refer to page 116 of the TSE
`

`
`
`
`Page 26 of 71
`
`
`
`Page 27
`
`document. It's in the box with the exclamation
`
`point in there. It's the second bullet point.
`
`The information of the over and under fields is
`
`not displayed if the screen is scrolled.
`
` So if you look at the scrolling operation
`
`figure that's below, you could see there's the
`
`first one, which is in a non-scrolling mode. When
`
`it's switched to a scrolling screen mode, the over
`
`and under that was in the first piece is no longer
`
`there. And then, when you go back to the basic
`
`board screen mode, the over and under come back
`
`and are displayed.
`
` So we'll go back to the compressed price
`
`display method that is being shown on page 12 of
`
`my declaration. It says over and under. That
`
`signifies that it is in a non-scrolling screen
`
`mode.
`
` Q Okay. When you're in a compressed mode,
`
`can you go from a non-scrolling screen mode to a
`
`scrolling screen mode?
`
` A Well, again, I'll refer back to page 115
`
`of the TSE document, that last bullet point. In

`Page 27 of 71
`

`
`Page 28
`
`addition, in a scrolling screen, the price display
`
`positions do not change automatically.
`
` And the previous one, which is talking
`
`about, in the compressed price display mode, the
`
`board display center price is automatically
`
`revised and displayed continuously at the center
`
`part of the board.
`
` Those two statements in conjunction seem
`
`to point to the fact that you can turn this from a
`
`non-scrolling mode to a scrolling mode.
`
` Q Okay. So let's get back to the original
`
`question I think I was asking you about the
`
`compressed mode when it's not scrolling. I want
`
`to limit my question to that -- my next question
`
`to that. Fair enough?
`
` A Compressed mode when it is non-scrolling.
`
`Okay.
`
` Q Right. And, again, I'm going to refer
`
`you back to your declaration on page 12, which is
`
`the figure on the right. That is the compressed
`
`mode, non-scrolling, correct?
`
` A Compressed mode, non-scrolling, yes.

`
` Q Okay. Do you see the price 004 in that
`
`screen?
`
` A The price 004, yes. 004.
`
` Q Is that in the center of the compressed
`
`mode screen?
`
` A It looks to be approximately in the
`
`center, yes.
`
` Q And just so I'm clear, where price 004
`
`is, that's the center position of the compressed
`
`mode, correct?
`
` MR. BEMBEN: Objection. Foundation.
`
` THE WITNESS: Well, when referencing the
`
`size of the window compared with the
`
`non-compressed price display method figure, it
`
`appears there are nine lines in total. And so
`
`it's the fifth line up that would be the center.
`
`So it looks to be in approximately the same
`
`location in the compressed price display figure.
`
`So, yes, I'd say that is in the center.
`
`BY MR. GANNON:
`
` Q Okay. And in this particular figure on
`
`the right on page 12 of your declaration, the

`
`
`
`Page 29 of 71
`
`
`
`center price is 004, correct?
`
` A I believe I answered that question
`
`Page 30
`
`already.
`
` Q And that's yes?
`
` A Yes.
`
` Q Okay. And the center price will always
`
`appear at this position in the compressed mode,
`
`correct?
`
` A Again, I'll refer you to page 115 of the
`
`TSE document. In addition, in a scrolling screen,
`
`the price display positions do not change
`
`automatically.
`
` So if we are limited to the non-scrolling
`
`mode, then the board display center price,
`
`whatever that happens to be, that is what will be
`
`displayed at the center of the board continuously.
`
` Q I'm still asking about non-scrolling.
`
`You understand that, right?
`
` A Sorry, I guess I -- it's sometimes hard
`
`to keep all the context in place. But, yes, if
`
`it's non-scrolling, then whatever is defined as
`
`the board display center price will be displayed

`

`
`at the center of the screen continuously.
`
` Q Okay. So, for example, on the figure on
`
`the right on page 12, the center price will never
`
`appear in the position marked 007, correct?
`
` MR. BEMBEN: Objection. Foundation.
`
`BY MR. GANNON:
`
` Q And, again, I'm limiting my question to
`
`non-scrolling.
`
` A "Never" is a very strong word. So it
`
`depends on what is defined as the board display
`
`center price. So what it is in this case, I could
`
`not be 100 percent certain, but if it is last
`
`contract price, if it traded at 007 for its
`
`last -- the last time, then 007 would become the
`
`center -- the board display center price and
`
`would, therefore, be displayed in the middle.
`
` Q Yeah, but I'm asking you about what's
`
`shown on page 12 of your declaration. The center
`
`price is 004, right, in the non-scrolling mode?
`
` A Okay. I just want to make sure I have
`
`the question, again, just so that I --
`
` Q Okay. So on page 12 of your declaration,
