`
` EXAMINATION BY COUNSEL FOR THE PETITIONER
`
` BY MR. MILLER:
`
` Q. Good morning, Dr. Koopman.
`
` A. Good morning.
`
` Q. Thank you for being here this morning.
`
`I'd like to start off by finding out whether or not
`
`you've actually ever had your deposition taken before?
`
` A. Yes, I have.
`
` Q. About how many times?
`
` A. I'd have to check my CV for an exact
`
`number, but round number is ten.
`
` Q. Ten. So you know the general ground
`
`rules?
`
` A. I do.
`
` Q. So I'll -- I'll just reiterate the ones

`CONDUCTED ON TUESDAY, JANUARY 13, 2015
`
`9
`
`3 (Pages 9 to 12)
`
`11
`
`that I find most important.
`
` A. Okay.
`
` Q. The first is, is that while I've never
`
`worked with Connie, our court reporter, I'm sure she's
`
`terrific. But as great as I'm sure she is, there's no
`
`way she's going to be able to take down every word if
`
`everyone in the room is talking over each other. And
`
`so I'd would appreciate it, and I'll do my best at
`
`this too, is if I'm speaking, if you can let me finish
`
`and I'll do my best to let you finish as well. Is
`
`that okay?
`
` A. Okay. No problem.
`
` Q. Also, we -- this deposition is being
`
`taking -- being taken for two different inter partes
`
`review proceedings, which I'm sure you understand;
`
`right?
`
` A. Yes.
`
` Q. And so the very nature of that is going
`
`to require that sometimes we -- we have two different
`
`exhibits that are oftentimes the same that are being
`
`numbered differently. And I know that's a little

`
`20
`
`21
`
`22
`
` A. I understand.
`
` Q. Great.
`
` So I'm going to start by have --
`
`providing you with copies of the declarations you
`
`filed or that you prepared in each of the IPR
`
`proceedings that we're here to discuss today.
`
` The first, which was filed in the IPR
`
`2014-00518 proceeding was marked as Exhibit 2208. And
`
`the second was filed in the IPR proceeding case number
`
`IPR 2014-00519, and that was marked as Exhibit 2302.
`
` (Exhibits 2208 and 2302 were
`
`entered for reference.)
`
` MR. HAIGHT: Thank you.
`
` Q. Have you had a chance to look at those
`
`two different exhibits?
`
` (Witness reviews document.)
`
` A. Yes, these look like the two reports I
`
`filed.
`
` Q. Thank you.
`
` Can you tell me if there are any
`
`differences substantively between the two reports?
`
` A. I -- I think there's a footnote that
`
`confusing. But we're -- we're going to have to work
`

`16
`
`17
`
`18
`
`19
`
`20
`
`21
`
`22
`
`with each other on that. Is that okay?
`
` A. Sure. As long as I understand when
`
`two documents are supposed to be the same, then
`
`I'll be fine.
`
`1
`
`2
`
`3
`
`4
`
`somehow ended up in one or the other, but I --
`
`there -- I don't intend there'd be any substantive
`
`differences that I recall.
`
` Q. Okay. Other than the case number and
`
` Q. All right. That's in both of our
`
`5 maybe the footnote?
`
`interests, so we'll do our best on that.
`
` Are you under -- is there any reason that
`
`we should be aware of that would prevent you from
`
`testifying truthfully today?
`
` A. I -- I should be fine.
`
` Q. And one more thing, I'm -- I'm going to
`
`be asking you questions today, obviously you've seen
`
`this process before. And I'll do my best to ask
`
`questions that are clear and make sense. But if I ask
`
`you a question that you don't understand, could you
`
`please let me know, and I'll try to ask it a different
`
`way.
`
` A. Sure.

`

`

`
`16
`
`17
`
` A. Case number, stuff like that. Yeah.
`
` Q. Okay.
`
` A. I don't -- I -- as I sit here, I can't
`
`recall any substantive difference.
`
` Q. Okay. Just so our lives are a little bit
`
`easier today, what I'd like you to be able to do is
`
`use Exhibit 2208; and if it's okay with you, I'd like
`
`to just use that one today so that we don't have to
`
`reask the same question over and over again for the
`
`other declaration.
`
` A. Sure, that's fine with we. If for
`
`some reason something I'm not thinking of comes to
`
`18 mind, I'll let you know but --
`
` Q. You under -- I want you to understand
`
`that if you answer a question, every -- everyone is
`
`going to be -- be under the belief that you understood
`
`the question. Is that -- do you understand that?
`
`19
`
`20
`
`21
`
`22
`
` Q. Thank you.
`
` A. -- as far as I know, we can just talk
`
`about one and that should cover everything.
`
` Q. Okay. And I'll try to identify both.

`

`
` A. I'll -- I'll assume you mean both.
`
` Q. Yeah.
`
` A. Okay, no problem.
`
` Q. So if you could turn to Exhibit 2208,
`

`
`17

`
`19
`
`20
`
`21
`
`22
`
`to be spending a lot of time in this document today,
`
`obviously. But I'd to actually like to start by
`
`looking at Paragraph 1.
`
` A. Okay.
`
` Q. The first Paragraph, it starts off saying
`
`that you've been retained by the patent owner,
`
`Rembrandt.
`
` A. Yes.
`
` Q. Do you see that?
`
` Do you know when you were retained?
`
` A. I looked it up, as I recall, it was
`
`about three months ago.
`
` Q. Do you recall who reached out to you?
`
` A. Oh, boy. I don't remember. There --
`
`there were several people involved. I don't
`
`remember who this was, the first phone call was.
`
` Q. I saw in your CV though it looks like you

`

`

`
`19
`
`20
`
`21
`
`22
`
` Q. And before you started work on this case,
`
`had you ever heard of this guy?
`
` A. No.
`
` Q. That guy being Mr. Bremer?
`
` A. Mr. Bremer, right.
`
` Q. Okay. Thank you.
`
` So -- now you said you did some work this
`
`week. Was that done in preparation for your
`
`deposition today?
`
` A. Yes.
`
` Q. Can you tell us what you did to prepare
`
`for your deposition?
`
` A. I spent a couple hours reading
`
`documents on Monday night, and then I had a meeting
`
`yesterday afternoon, evening for a few hours.
`
` Q. Was that meeting with Mr. Haight?
`
` A. Yes.
`
` Q. What documents did you review to prepare?
`
` A. I looked at my declaration and went
`
`back to look at the patents. I looked through some
`
`pieces of some other things, you know, I don't --
`
`if -- if the list is important, I can try to

`

`
`21
`
`22
`
`do do some expert witness things, so it's not --
`
`wasn't something that came completely out of the blue;
`
`right?
`
` A. It was out of the blue in terms of it
`
`being a cold call.
`
` Q. Yeah.
`
` A. But you know the -- I -- I do not
`
`publicly advertise by expert witness, but as a
`
`professor university, most of us get these calls
`
`all the time, so it was nothing unusual to be
`
`called.
`
` Q. Okay. And from the time that you've been
`
`retained up until you -- this -- dec -- these two
`
`declarations were prepared, about how much time did
`
`you put into this case?
`
` A. It was about 45 hours excluding this
`
`week. So -- let me say it a different way. I -- I
`
`billed for about 45 hours and -- and haven't done
`
`this week yet.
`
` Q. Have you ever talked to the inventor of
`
`the '580 patent?
`
` A. Not that I can recall.

`

`
`16
`
`17
`
`18
`
`remember, but it was mostly -- it was mostly the
`
`documents -- some of the documents that are in my
`
`appendix of materials. So I looked at the patents.
`
`I looked at a couple pages of Dr. Goodman's -- I
`
`think it was his deposition. I know I looked at
`
`his declaration as well. I read my article again.
`
`And I may have looked at some of the other stuff.
`
`I don't recall the whole list.
`
` Q. Do you remember what pages of
`
`Dr. Goodman's deposition you looked at?
`
` A. I -- I don't remember. I mean, I --
`
`at one point I read the whole thing, just not this
`
`week.
`
` Q. Did you ever -- it's not listed here, but
`
`I'm just wondering. Did you ever look at any of the
`
`expert reports that were prepared in the litigation
`
`that's going on between Rembrandt and Samsung?
`
` A. I have not seen those -- well, let
`
`19 me -- let me clarify that. I -- I think I looked
`
`20
`
`21
`
`22
`
`at a couple paragraphs from Dr. Akl's report,
`
`A-K-L, which were summarizing our phone
`
`conversation. But beyond that, I have not looked

`
`at any of that material.
`
` Q. So you had a phone conversation with
`
`Dr. Akl?
`
` A. Yes, this is a few months ago. Well,
`
`a few weeks ago. I don't remember exactly when. I
`
`would have to look it up.
`
` Q. When you spoke to him, did you understand
`
`that he had been retained by Rembrandt in the
`
`litigation?
`
` A. Yes, that was my understanding.
`
` Q. Who set that call up?
`
` A. Again, there were -- there were -- the
`
`litigation folks were involved. I don't know who
`
`exactly told me, but -- but it was a phone call
`
`that had been set up, you know, at the request of
`
`litigation folks.
`
` Q. In your work in this matter, who retained
`
`you?
`
` A. I was actually retained both by
`
`litigation and by the IPR. The litigation folks
`
`contacted me first, and I did a couple hours work

`
` Could you turn, please, to Paragraph 5 of
`
`your declaration. That's Exhibit 2208 and 2302.
`
` A. I'm sorry, Paragraph 5?
`
` Q. Yes.
`
` A. Not page 5. Okay. Okay. Got it.
`
` Q. In that paragraph -- I'm summarizing;
`
`tell me if my summary is wrong. You talked about you
`
`worked with some students on embedded networks, and
`
`there's a reference to a controller area network.
`
`Or -- testbeds?
`
` A. Yes.
`
` Q. Do you see that? Can you tell us what a
`
`controller area network testbed is?
`
` A. Controller area network is a protocol
`
`widely used in automobiles and -- and many other
`
`things from Bosch. And by testbed, I mean we
`
`bought some personal computers and installed CAN
`
`interface cards in them and used it for experiments
`
`on embedded networks.
`
` Q. Now, out of curiosity, why did you buy
`
`this piece of equipment?
`
` A. I do research in embedded networking,
`
`for them, almost nothing, and then I switched over

`
`to IPR.
`
` Q. Uh-huh.
`
` A. And I have not done any litigation
`
`work since I started IPR.
`
` Q. Do you remember who on the litigation
`
`side you worked with?
`
` A. I remember Mr. Engellenner's name.
`
` Q. When was the last time you spoke to
`

`

`

`
` A. He was on the phone when -- he was on
`
`the phone yesterday to talk about Dr. Akl's
`
`declaration, just to make sure I -- I remembered
`
`the conversation.
`
` Q. About how long were you on the phone with
`
`Dr. -- Dr. -- excuse me. How -- about how long were
`
`you on the phone with Mr. Engellenner yesterday?
`
` A. Wow, I didn't time it. 30 minutes.
`
`It was only a very short portion of the day.
`
` Q. That was during the time you were working
`
`with Mr. Haight to prepare for today?
`
` A. Yes.
`
` Q. Thanks.

`
`and -- and back then did quite a bit of research in
`
`it. And in fact, the customer for some of that
`
`research was Bosch, who invented controller area
`
`networking.
`
` Q. So --
`
` A. I -- I wanted to have a realistic way
`
`to -- to do my experiments.
`
` Q. Can you give us a brief technical
`
`description of what a controller area network is.
`
` A. It's -- it's a complicated subject, so
`
`I can be very brief. This is a two-hour lecture,
`
`which I don't think you want.
`
` Q. You're right.
`
` A. But the -- but -- we can go get the
`
`PowerPoint off the web, but the -- the simple
`
`version -- and if I'm not being deep enough, let me
`
`know -- is that in -- in cars they wanted a
`
`particular fairly standardized network protocol
`
`that needed some specific characteristics, such as
`
`prioritization, and so some folks came up with one
`
`way to decide who gets to transmit next on the
`
`network. It uses a technique called binary

`countdown with bit dominance and -- to determine
`
`which message goes next, based on priority. And
`
`it's optimized for things that look like cars, in
`
`terms of network speed, physical characteristics,
`
`and maximum network length. And -- and there's --
`
`there's a lot more, of course.
`
` Q. Of course.
`
` When you said prioritization, you used
`
`that term, can you tell us what you mean by that.
`
` A. By prioritization, in some networks,
`
`what you want to do is make sure that high priority
`
`12 messages are always transmitted before low priority
`
`13 messages and CAN -- the binary countdown

`

`
` A. Okay, oh, you want me to explain?
`
` Q. Yes.
`
` A. You know, actually my -- the paper I
`
`wrote in the early '90s does a pretty good job of
`
`it, but I mean, I could just read out of the paper.
`
`I'm not quite sure what you're looking for.
`
` Q. I don't have the paper. Just generally
`
`speaking --
`
` A. Okay.
`
` Q. -- what's the difference?
`
` A. Generally speaking -- of course there
`
`are many differences. I'm not going to get them
`
`all sitting here. But as an example, in a
`
`14
`

`
`16
`

`
`18
`
`19
`
`20
`
`21
`
`22
`
`characteristic of CAN is specifically intended to
`
`14 master/slave system, you're going to expect that
`
`provide that functionality.
`
` Q. Is another word for this called
`
`controller area network testbed a CAN bus?
`
` A. I think there's a problem with the
`
`question in that testbed is not part of the usual
`
`phrase.
`
` Q. Okay. Well, is another word for
`
`controller area network a CAN bus?
`
`15
`
`16
`
`17
`
`18
`
`19
`
`20
`
`21
`
`22
`
`there's a master, and the master queries the slave
`
`nodes, and they're only going to respond when
`
`they're queried, and they're going to send their
`
`data back to the master. Whereas on CAN, at the
`
`time in the '90s, CAN was often called
`
`peer-to-peer. And the reason people would say that
`
`is, there's no master, you can just send the data
`
`wherever you want, whenever you want; although the

`
`10
`
`11
`
`12
`
`13
`
`14
`
` A. Some people call it that, yes.
`
` Q. What about you?
`
` A. Usually I call it CAN, because the N
`
`stands for network and bus would be redundant.
`
` Q. Okay.
`
` A. But I've probably called it CAN bus at
`
`some point, because so many people do.
`
` Q. Okay. Well, I'll -- I'll -- I'll try to
`
`just say controller area network, how about that?
`
` A. I'm okay with either one. I will -- I
`
`will know what you mean either way.
`
` Q. Is a controller area network, does it
`
`operate in a master/slave arrangement?
`
` A. It is not typically considered
`
`15 master/slave. It's considered binary countdown.
`
` Q. Do you have an understandsing as to what
`
`the difference is between a master/slave network and a

`

`
`whenever is conditioned by the fact there's this
`
`prioritization mechanism that arbitrates if there
`
`are multiple concurrent transmitters.
`
` Q. So I'm curious why you put Paragraph 5 in
`
`your declaration. Can you just give me an explanation
`
`for that.
`
` (Witness reviews document.)
`
` A. Oh, I was explaining about some of the
`
`experience I've had doing networking. That's one
`
`of my experiences, and in other paragraphs I
`
`explained other of my experiences.
`
` Q. Okay. Thank you.
`
` In -- in reviewing your declaration and
`
`some of the documents that are in this case, I've seen
`
`reference to media -- media access controller or MAC.
`
`Can you tell me what your understanding of a MAC is?
`
` A. In that context -- that acronym M-A-C
`
`binary countdown network like those used in controller
`
`18 means different things, but in that context, it's
`
`area networks?
`
` A. If we're going in generalalities, like
`
`how I would teach my course, yes.
`
` Q. Please.

`
`20
`

`

`
`level, the idea is that you have a shared wire, you
`
`have multiple transmitters who potentially may want
`
`to transmit at the same time. They have data to

`
`has to go next. And the MAC -- MAC as a concept is
`
`the concept of figuring out who gets to go next.
`
`And we use the word protocol associated with that.
`
`The protocol is the procedure for figuring out who
`
`goes next. And again, that's very high level, very
`
`simplified.
`
` Q. I'm going to provide you a copy of an
`
`exhibit that's already been marked. Actually, there's
`
`two exhibits. One is Exhibit 1218.
`
` MR. HAIGHT: Thank you.
`
` Q. And the other is Exhibit 1317.
`
` (Exhibits 1218 and 1317 were
`
`entered for reference.)
`
` A. Thank you. These both look the same
`
`to me.
`
` Q. Thanks. In that case, if they weren't,
`
`that would be my fault.
`
` A. Okay.
`
` Q. I'm going to work off of Exhibit 1218,
`
`but I wanted you to have 13, the other one there, just

`
` Q. So for lack of a better word, what I
`
`think of this is as the article, and maybe we'll call
`
`the other one your paper. How's that?
`
` A. Sure, if we want to call them that.
`
`But the paper came first.
` Q. Yeah.
`
` A. Okay.
` Q. I understand that.
`
` A. Okay. Okay. That's fine.
` Q. I will be helplessly confused if we call
`
`them the same thing.
`
` A. Okay. No problem.
` Q. So -- so before we -- we got the exhibit
`
`out, and we had that little discussion, we were
`
`talking and you were -- you were providing your
`
`understanding of what a media access controller is?
`
` A. Uh-huh.
` Q. And you gave an -- an explanation, and on
`
`the -- in the first page of your article, which is
`
`page 46 of the magazine.
`
` A. Uh-huh.
` Q. There's a statement that says, "At the

`
` Q. Now, there's a declaration attached to
`
`this from a librarian, but if you turn to the third
`
`page of the exhibit there's an -- there's an article
`
`on the Embedded Systems Programming journal. Within
`
`that there's an article written by Bhargav Upender and
`
`Philip Koopman.
`
` A. Right.
`
` Q. The -- the author listed as Philip
`
`Koopman, I assume that's you?
`
` A. That is me. And I recognize this
`
`article as the one I did way back then.
`
` Q. I was asking you about media access
`
`controller.
`
` A. Uh-huh.
`
` Q. And on page 46 of your article --
`
` A. Uh-huh.
`
` Q. -- and we should probably try to come up
`
`with a common parlance, because I know that in your
`
`declaration you attached another version of this
`
`article.

`
`it yet.
`
` Q. It's all the way at the bottom of the
`
`first column.
`
` A. I got it. Uh-huh.
`
` Q. The article states, "At the heart of the
`
`LAN is the media access protocol, which picks the next
`
`transmitter for access to the shared" -- I apologize,
`
`I can't read that word -- "work medium, typically a
`
`wire."

`

`
`about a media access protocol, is that synonymous, so
`

`

`

`

`
`the paper to tell you what I said, instead of what
`
`the editor changed it to.
`
` Q. Well, let me ask you this, when the --
`
`when the editor made changes, did you get a chance to
`
`sign off on those changes?
`
` A. No.
`
` Q. Why not?
`
` A. That's just not how it worked. It's a

`
` MR. HAIGHT: Counsel, you
`
`referred to this as the article. I assume this is
`
`what you meant to be the paper?
`
` MR. MILLER: Yes. I told you I
`
`was going to get confused.
`
` Q. Do you have your paper in front of you?
`
` A. Yes, I do.
`
` I want to clarify a previous answer.
`
`It might have been the case that Bhargav saw a
`
`draft of this. I know I didn't see it, but I was
`
`second author. But at any rate, I never sat down
`
`and -- and vetted the changes.
`
` Q. Okay. And you also never told the

`

`
`22
`
` Q. Well, did he make any changes to the
`
`17 magazine, Embedded Systems, that there was a problem
`
`article that you disagreed with?
`
` A. He made some changes that may have --
`
`that I know for sure changed wording. And in --
`
`you know -- in some cases, it -- it depends on the
`
`18
`
`19
`
`20
`
`21
`
`22
`
`with anything in it?
`
` A. I -- I -- I -- you know, after it was
`
`published, I don't think I sat down and read it
`
`critically to do that, but the answer to your
`
`question is I never went back and told -- told them

`

`
`article, do you recall whether or not you told the
`
`editor you didn't agree with what he did?
`
` A. I don't think I saw it until it got
`
`published, and there was no point -- I -- I did not
`
`review this article in detail with that in mind.
`
` Q. Do you know who the editor was?
`
` A. I'd have to go back to the front. Let
`
`13 me see if it's in here. There were several editors
`
`14
`
`15
`
`16
`
`in that era. I'm not sure which one it was.
