`
`will provide answers to those questions.
`
` A Exactly.
`
` Q If you don't understand my questions, you
`
`can just tell me, and I will try to explain it or ask
`
`it a different way. Okay?
`
` A Okay.
`
` Q And is there any reason you can't give
`
`truthful testimony today?
`
` A There is no reason.
`
` Q Doctor, I would like to hand you the
`
`declaration that you submitted in these three cases
`
`that's been marked as Exhibit 2042, I believe in each
`
`of the three cases.
`
` Is this in fact the declaration that you
`
`submitted in connection with the three IPRs?
`
` A It's a long declaration, but, yes, it
`
`appears to be.
`
` Q And at the end of it after page 88, your
`
`signature appears; is that right?
`
` A Correct.

`
`you signed it?
`
` A Yes.
` Q You believed it to be truthful before you
`
`signed it?
`
` A Yes, I did.
` Q And if you reviewed it and believed it to
`
`contain errors, you would have changed those errors
`
`before you signed it, correct?
`
` A Correct.
` Q Are you aware of any errors in your
`
`declaration as you sit here today?
`
` A Not as I sit today.

`

`
` Q And it says that you pioneered the
`
`development of science-driven biomimetic robots to
`
`study the basic mechanisms of flow control that lead
`
`to the outstanding agility of fish and cetaceans; is
`
`that right?
`
` A Yes.
`
` Q That's one of your research interests?
`
` A It is.
`
` Q And it says further down that you're
`
`currently studying the physics of flow sensing in
`
`fish and marine mammals to achieve
`
`supermaneuverability in ocean vehicles through flow
`
`feedback control; is that right?
`
` A Right.
`
` Q That's another one of your research
`
`interests?
`
` A Yes.
`
` Q There's nothing in the summary of your
`
`research interests about marine seismic surveys,

`
`developed on fish hydrodynamics and the like sprang
`
` Q Okay. Now, appended to your declaration
`
`was Exhibit A to 2042. I suppose we can mark this
`
`as -- let's keep this as part of 2042 since that's
`
`how it was submitted in connection with your
`
`declaration.
`
` And for the record, I'm also handing you
`
`what was marked as Exhibit B to your declaration,
`
`2042, as well as Exhibit C to your declaration, 2042.
`
` Do you have those documents, sir?
`
` A Yes, I do.
`
` Q Exhibit A is a copy of your curriculum
`
`vitae; is that right?
`
` A Yes, it is.

`
` Q But with respect to marine seismic
`
`surveys, there is nothing in the summary of your
`
`research interests that talks about that, right?
`
` A It is implied, as I told you, and if you
`
`look back in my references you can find plenty of
`
`such references. So this is -- we're looking at the
`
`cutting edge of the moment which we will advertise in
`
`this caption. This is for various reasons.
`
` Q It's for various what?
`
` A We do this for reasons of promoting the
`
`students and the like. But this whole research area
`
`came as a result of my cable mechanics, which is my
`
`sort of bread and butter. That's how I got tenure at
`
` A Yes.

`
` Q And your curriculum vitae provides some
`
`of your research and experience, right?
`

`
`interests, it does not say anything about marine
`
`seismic surveys, right?

`
` Q I understand that, but my question is
`
`very simple. You don't discuss in that paper marine
`
`seismic survey.
`
` MR. KIKLIS: Objection. Form.
`
` THE WITNESS: The fundamental --
`
` MR. KIKLIS: Michael, let me get a chance
`
`to object.
`
` Objection. Form.
`
` THE WITNESS: The fundamentals for the
`
`paper are very pertinent, whereas you can find from
`
`not appear in the 21-page curriculum vitae, correct?
`

`
` A It is an application of all the things
`
`that I have published on the dynamics of translating
`
`cables. For example, number 8 on dynamics of --

` THE REPORTER: Excuse me?
`
` THE WITNESS: Number 7 and 8 of my

`
`you cannot do towed arrays.
`

`
`BY MR. BERL:
`
` Q Those are on page 11?
`
` A Page 11, number 2. "Dynamics of cables,
`
`Towing Cables and Mooring Systems." The Shock and
`
`Vibrations Digest is a journal where people review
`
`the literature to find out what is the state of the
`
`art, what is the most advanced, what is missing from
`
`the area. Whereas, you can see I reviewed the
`
`relevant area which is where all the work on towed
`
`arrays is based on.
`
` Q Let's take a look at reference number 7
`
`that you identified. That's on page 3. That's the
`
`Kim article from 1984. Correct?
`
` A Yes.
`
` Q That does not address marine seismic
`
`surveys, does it?
`
` A It has applicability to it, not in -- in
`
`the application of commercial application. But all
`
`this work was the basis for deriving the fundamentals
`
`of how towed arrays and the like move.

`
`that paper does not discuss marine seismic surveys,

`
`that apply to the towed arrays.

`
` Q Okay. I understand. So your answer is
`
`it does not discuss marine seismic surveys but it
`
`applies to marine seismic surveys.
`
` A It discusses the principles of seismic
`
`arrays; therefore, it applies to seismic arrays.
`
` Don't change my answer, please.
`
` Q I'm not changing your answer. I'm trying
`
`to get an answer to the question which is --
`
` A And you got the answer.
`
` Q I don't think you've answered my narrow
`
`question, which was paper number 7 does not discuss
`
`in the paper marine seismic surveys, correct?

`
` A Or a person like me.
`
` Q Let's take a look at number 2, this
`
`review paper you identified on page 11.
`
` A Yes.
`
` Q From 1991. That likewise does not
`
`discuss marine seismic surveys, correct?
`
` A Towing cables.
`
` Q It discusses towing cables, but not the
`
`problems associated with marine seismic surveys, for
`
`example.
`
` A I have to look back whether I used in
`
`fact the word, because I meant -- I believe -- which
`
` A It discusses the principles that apply to
`
`13 my memory from so many years is not exact, whether in
`
`seismic arrays.
`
` Q Okay. Paper number 8 that you identified
`
`as well, that likewise does not discuss marine
`
`seismic surveys, correct?
`
` A We can go down the list, and I will give
`
`you the same answer which you heard before.
`
` Q Which is that it does not discuss marine
`
`seismic surveys, but in your view it applies to
`
`14

`
`16
`
`17
`
`18
`
`19
`
`20
`
`21
`
`22
`
`this publication, but I think it was in that one I
`
`discussed towed arrays as an application. I have to
`
`look at that to reinforce my memory which one it is.
`
` Q Towed arrays in marine seismic surveys?
`
` A Towed arrays.
`
` Q But not in marine seismic surveys, just
`
`in general.
`
` A Towed arrays. Whether it is behind
`
`submarines, which was my primary field of study at
`
`22 marine seismic surveys.
`
`1
`
`2
`
`3
`
`4
`
`5
`
`6
`
`7
`
` A No, not the way you put it. The answer
`
`is it applies to the principles; therefore, it
`
`applies to seismic arrays.
`
` Q But that marine seismic surveys are not
`
`explicitly discussed in the article number 8.
`
` A When you discuss the principles of
`
`something, it applies to those principles. That's
`
`8 my position.
`
` Q But you discussed the principles. You
`
`did not discuss marine seismic surveys.

`
` Q So the information that one can determine
`
`based on work on submarines, for example, you view as
`
`being applicable to the context of marine seismic
`
`surveying.
`
` A Submarines is more challenging than for
`
`gas and oil.

`
` Q I didn't hear the end of what you said.
`
` A Someone who is studying the towed arrays
`
`will have to look at my publications; therefore, it's

`
` MR. BERL: No, that's fine. No apology
`
`necessary.
`
`BY MR. BERL:
`
` Q Doctor, in the field of marine seismic
`
`surveying, you would agree that Dr. Evans has more
`
`expertise than you do.
`
` A It depends on how you put it. If you are
`
`talking about what we are talking today, the dynamics
`
`of towed arrays, which is what is the field of these
`
`publications, I would claim that he is not more
`
`expert than I am. In fact, I would say the opposite.
`
`In fact, I would say few people in the world would be
`
`on the same level.
`
` Q But if we're talking about what problems
`
`are encountered in the field when conducting marine
`
`seismic surveys, you would agree that in that area
`
`Dr. Evans has more expertise than you do?
`
` A Not in the field of towing arrays. You
`
`can talk about binning, you can talk about throwing
`
`additional lines. I think the specific field of
`
`pertinence, I believe I have more expertise.
`
` Q But when we talk about binning or towing

`
`19
`
`20
`
`21
`
`22
`
`you don't want to compare. How many marine seismic
`
`surveys have you designed?
`
` A Specifically for the industry, I'm not a
`
`designer of arrays. I'm the developer of the
`
`technology which is used -- fundamentals of dynamics
`
`and control, which are used to design such arrays.
`
` Q So it's correct to say that you have
`
`designed zero marine seismic surveys.
`
` A Design in the sense of actually doing
`
`them, this is not my business. I'm a professional
`
`who develops concepts and new technology.
`
` Q But with respect to designing how a
`
`survey should be conducted in a particular area,
`
`let's say the Gulf of Mexico, in a marine seismic
`
`survey, that's not your area.
`
` MR. KIKLIS: Objection. Form.
`
` THE WITNESS: There are aspects of it
`
`which I'm very pertinent with, okay? So if someone
`
`in the industry calls me up, it's usually for some
`
`advanced problem, and I will be part of the team.
`
`Now, how you want to grade this up or down, it's a
`
`personal choice.

`

`

`
`14
`
`additional lines, in those areas Dr. Evans has more
`
`expertise?
`
` A He has expertise in certain areas. I'm
`
`not sure that this is the specific one. I'm just
`
`saying that -- I don't want to compare the other
`
`areas, but in the specific area of the patents which
`
`we're talking about today, I believe I have more
`
`expertise than he does.
`
` Q And that specific area that you said you
`
`think you have more expertise is the dynamics of
`
`towed arrays, correct?
`
` A And control, yes.
`
` Q And with regard to designing marine
`
`seismic surveys, you would agree that Dr. Evans has
`
`15 more expertise than you.
`
`16
`
`17
`
`18
`
` A I would put the doubt on this because in
`
`order to do proper design of the arrays, you have to
`
`know about the dynamics of the control. You may know
`
`19 more on acoustics or anything else. I'm not saying
`
`20
`
`21
`
`22
`
`that Dr. Evens does or does not, but I'm saying in
`
`the field of study today.

`
`seismic survey"?
`
` MR. KIKLIS: Objection to form.
`
` THE WITNESS: I told you that my review
`
`papers apply to towing arrays, okay? You want -- for
`
`us, towed arrays is equivalent to whether it's a
`
`towed array behind a submarine or whether it's behind
`
`-- towed arrays behind a vehicle. So it's similar to
`
`what you are talking about.
`
`BY MR. BERL:
`
` Q And I think the answer to my question,
`
`but please confirm for me if I'm wrong, is you cannot
`
`identify for me a single thing you have ever written

`

`

`
`problems associated with marine seismic surveys, have
`

`
`you?
`
` A I have written notes which provide the
`

`
`you've ever written, other than your expert reports
`

` THE WITNESS: For a person like yourself,
