`bit.
` Q. I'm sorry. I'll try again today.
` Would you please state your full name for
`the record?
` A. Larry Dowd Hartsough.
` Q. And I know you've been deposed several
`times in the last couple of weeks, but I'll just go
`over the ground rules because that may be helpful.
` You understand that you've taken an oath to
`tell the truth today?
` A. Yes.
` Q. And your testimony will be truthful?
` A. Yes.
` Q. And your answers to my questions will be
`complete?
` A. Yes.

` A. Yes.
` Q. Have you ingested anything that could
`impair your ability to testify truthfully and fully
`today?
` A. No.
` Q. If you, at any point, don't understand any
`question or you haven't fully heard it, will you
`please let me know?
` A. Yes.
` Q. And if you answer a question, then I'll
`assume that you've heard it fully and understood it.
` Is that fair?
` A. Yes.
` Q. What did you do to prepare for today's
`deposition?
` A. I met with counsel and reviewed some of the
`prior art and relevant documents, such as my
`declaration and the patents -- declarations and
`patents.
` Q. When did you meet with counsel?
` A. Over the last three days, Sunday through
`Tuesday.
` Q. And for how long each day?

`
` Q. Over the three days?
` A. That's correct.
` Q. And which items of prior art did you review
`in preparation for this deposition?
` A. Mainly the prior art cited in the grounds
`by the Board. I may not be able to list them all
`off the top of my head, but --
` Q. Can you list any of them?
` A. By -- not by a full title, but the Wang
`patents -- yes, I can list some of them.
` Q. Okay. Please do.
` A. As I said, it's not exhaustive because I
`don't -- didn't memorize the list, memorize what I
`looked at, but the Wang patents and the Kudryavtsev
`article and Mozgrin's thesis and a Yamaguchi patent
`and several more that I can't recall the names of
`the authors right at this moment.
` Q. And other than those pieces of prior art
`and your declaration and the '759 patent, did you
`review any other documents in preparation for this
`deposition?
` A. Well, as I told you, the list of prior art
`that I gave you is not -- not complete. I didn't
`review any documents that have not been listed as
`relevant to the case.

` Q. You --
` A. As I said, I don't -- I may have briefly
`referred to other documents for specific, narrow
`items. But those would have been listed in, you
`know, as -- as part of the case already. There was
`nothing outside of that scope.
` Q. When you say "listed as part of the case,"
`are you referring to documents that would have been
`identified in your declaration?
` A. There may have been a document listed in my
`declaration that I didn't review in the last -- that
`I didn't review.
` Q. I understand.
` I'm just trying to understand which
`documents you looked at in preparing to testify here
`today.
` And so my question is: Is everything that
`you looked at in preparing for the deposition either
`listed in the declaration or the declaration itself?
` MR. SADOWITZ: Objection; form.
` THE WITNESS: I am not sure I -- is
`everything that I looked at?
`BY MR. FITZPATRICK:
` Q. In preparing for today's deposition.
` A. Again, I am not sure I can answer that

`question without looking at both my declaration and
`what -- what documents are -- what documents are --
`were listed as the grounds by the Board for the
`various claims to see if I looked at any documents
`that were outside of that.
` Q. You understand that today's deposition
`pertains to United States Patent Number 7,147,759?
` A. That's -- yes.
` Q. And if I refer to that as the '759 patent,
`you will know what I am referring to?
` A. Yes.
` Q. I am going to hand you what has been marked
`already as Exhibit 2005. Please take a look at it
`and tell me if you recognize it.
` A. Yes.
` Q. What is it?
` A. It's my declaration in regard to the '759
`patent.
` Q. And on the last page of the declaration, it
`doesn't have a page number, but it's page 100, I
`believe.
` Is that your signature?
` A. Yes.
` Q. Do you know why it is that the preceding
`pages of the declaration have page numbers but your

` A. No, I wasn't responsible for pagination.
` Q. Did you sign this declaration on
`December 30, 2014?
` A. Yes.
` Q. If you could please look at paragraph 3 of
`the declaration on page 1.
` That paragraph begins:
` "The list of materials I considered in
` forming the opinions set forth in this
` declaration includes" -- and then it lists
` various documents.
` Do you see that?
` A. Yes.
` Q. What other documents or materials did you
`consider in forming the opinions set forth in your
`declaration?
` A. As I said, I would have to review the prior
`art references discussed, as I don't remember all of
`them off the top of my head. I can't make a list.
` So, you know, I can't just answer that
`question as I sit here today. I can't answer that
`question, "what other documents," unless I eliminate
`whether they're part of this list or not -- whether
`I determined whether they're part of this listing

` Q. Well, you -- presumably you reviewed the
`Wang patent in connection with forming your opinions
`relating to the '759 patent; right?
` A. Yes.
` Q. And you reviewed the Kudryavtsev article or
`paper in connection with the '759 patent; is that
`correct?
` A. Yes.
` Q. And you reviewed the Yamaguchi reference in
`connection with the '759 patent?
` A. Yes.
` Q. And you reviewed the Müller-Horsche
`reference in connection with the '759 patent, if you
`look at page 87 of your declaration?
` A. Yes.
` That's to answer your question. Yes, I
`looked at the Müller-Horsche.
` Q. And did you look at the Li, L-I, reference
`in connection with the '759 patent?
` A. When? In the last three days or...
` Q. The questions that I am asking you right
`now, Doctor, pertain to paragraph 3 of your
`declaration, which says that the list of materials
`that you considered in forming the opinions set

`forth in your declaration includes, and then it
`lists various items.
` A. Yes.
` Q. And I am trying to understand which items
`you considered in forming the opinions set forth in
`your declaration.
` So my question is: Was one of the items
`the Li reference?
` A. I would have to look at -- I -- I -- it's
`been three months, and I don't recall. I would have
`to look at it. But I -- it was material that I
`would have reviewed back in December, and I just --
`I just don't recall the details of it.
` Q. Look at page 86 of your declaration,
`please.
` A. Okay, yeah.
` Q. If you could please read to yourself
`paragraphs 162 and 163 and let me know when you're
`done.
` Does that refresh your memory as to whether
`you reviewed and considered the Li reference in
`connection with the '759 patent?
` A. Yes.
` Q. And you did, in fact, consider it?
` A. Yes.

` Q. Okay. Now, looking again at paragraph 3 of
`your declaration on page 1.
` Other than the items -- the materials that
`are specifically identified in that paragraph, are
`there any other materials that you considered in
`forming the opinions set forth in your declaration
`concerning the '759 patent?
` A. Not that I -- not that I recall, but I
`might -- might have considered some other materials,
`maybe perhaps to illustrate my opinion. But again,
`at the moment, I don't recall.
` Q. There's nothing at all that you remember
`other than what's identified in paragraph 3?
` MR. SADOWITZ: Objection; form.
` THE WITNESS: Not that I recall at the
`moment.
`BY MR. FITZPATRICK:
` Q. If at any point during the day you remember
`anything, would you please let me know?
` A. Yes.
` Q. Now, directing your attention back to your
`preparation for this deposition, having in mind the
`materials that are identified in paragraph 3 of your
`declaration, is there anything other than your
`declaration itself and the materials identified in

`deposition?
` A. Again, without a review of -- a summary of
`the prior art references, which I don't have in
`front of me, and comparing that to what I did
`review, I just can't tell you.
` I would have to eliminate the ones that are
`prior art references. But again, I don't -- I don't
`think I did.
` Q. If you remember anything during the course
`of the day, will you please let me know?
` A. Yes.
` Q. Have you reviewed any of the transcripts
`from your prior depositions in the Zond IPR
`proceedings?
` A. I looked briefly at the first one, but I
`did not review the entire transcript. I just looked
`at it briefly.
` Q. When did you look at that?
` A. The day -- it would have been, like, two
`days after I gave it. It was just the -- what do
`you call it? -- the rough.
` So I noted that there were a lot of
`corrections, probably, to some of the technical
`terms and so on, but, you know, other than that,

`been several days after the -- after that
`deposition.
` Q. Was there any particular portion of that
`transcript that you looked at?
` A. No. I don't recall.
` I looked at it and noted that it was --
`that I wasn't going to have time to do any
`correction -- any review for corrections of
`terminology or anything like that.

`it, and at this point I don't recall what portion I
`looked at.
` Q. How long did you spend reviewing it?
` A. Maybe 15 or 20 minutes.
` Q. What was your purpose in reviewing it?
` A. Well, it was sent to me, and I wanted to
`see if my answers were kind of -- you know, were
`clear. But I got -- if my answers were clear in
`what I -- in what I really meant to say, but I
`didn't -- I don't recall any -- the specific -- at

`looked at.

` Q. I am handing you what has been marked as
`TSMC 1201. It's a copy of the '759 patent.
` Please feel free to review it, Doctor.
` But I just want to direct you again to
`paragraph 55 of your declaration and the language
`that you use here: "A particular structure."
` I am asking you now about "a particular
`structure," and I am asking you to explain what you

` Well, what I mean by that language is that
`there are particular aspects to the structure.
`They're not necessarily all in one embodiment. I
`wanted to make that clear, and that's not my
`complete answer.
` So it's not -- not exhaustively aspects of
`this structure or the relationships between the
`anode and the cathode -- the gas flow -- gas flow
`location and the -- the power supply and what it can
`do.

` Q. What do you mean by "geometrically,

` A. Where they are in relationship to one
`another and their role in the parameters of the
`claimed -- the claimed process of generating the
`strongly-ionized plasma.
` Q. Now, your sentence here in paragraph 55 of
`your declaration refers to Figure 2 of the '759
`patent, and then, as we noted, you reproduced
`Figure 2.
` Does Figure 2 illustrate the geometric and
`structural relationship between the anode and the

` Q. What aspect of the gas flow location is
`relevant to the particular structure that you've
`identified in paragraph 55?
` A. Please repeat the question again.
` Q. I had asked you about the particular

`you -- when using this language "a particular
`structure" here in paragraph 55, and one of those
`that you identified was the gas flow location.
` And I am asking you what aspect of that is

`illustrates the gas flow -- it doesn't illustrate
`the gas flow in that -- let me take a moment.

` The particular aspect, it is shown in
`Figure 2, but not specifically discussed in
`relationship to that figure.
` But the aspect that is particular is the
`inlet of the gas such that it can flow into the

`supply is not specifically mentioned, but in
`relationship to Figure 10, the -- an output of the
`pulsed power supply and the DC power supply are
`connected to one another in the sense that an output
`of the pulsed power supply can affect the electric

` Paragraph?
` Q. Fifty-five.
` A. Fifty-five.
` Q. There's a reference in paragraph 55 to a
`particular type of voltage pulse.
` Do you see that in the fourth line of the
`paragraph?
` A. Yes.
` Q. What did you mean by that?
` A. The pulse has charac- -- various
`characteristics that -- among which, you know, the
`amplitude, the shape, including the rise time and
`fall time, and the pulse width, and the type of
`pulse.
` Q. What do you mean by "the type of pulse"?
` A. Whether it's a power pulse, a voltage
`pulse.
` Q. Which is it?
` A. Well, it's not an either-or. He discusses
`both.

` "Pulsing the power applied to the plasma
` can be advantageous since the average
` discharge power can remain low while
` relatively large power pulses can be
` periodically applied."
` Do you see that?
` A. Yes.
` Q. And then he says:
` "Additionally, the duration of these large
` voltage pulses can be preset so as to
` reduce the probability of establishing an
` electrical breakdown condition leading to
` an undesirable electrical discharge."
` Do you see that?
