`
`break, feel free to let me know.

`
` Q. Post high school.
`
` A. After a year at a community college, I
`
`moved to the University of North Carolina at
`
`Charlotte where I obtained a bachelor's degree in
`
`chemistry in 1980.
`
` Upon completion of that, I was
`
`accepted for graduate school, graduate studies at
`
`Michigan State University in inorganic chemistry,
`
`which I completed in 1986, defended my
`
`dissertation.
`
` For two years plus after that I was a
`
`post-doctoral researcher at Texas A & M
`
`University, again, in inorganic chemistry.
`
` Q. What is inorganic chemistry?

`
` A. Inorganic chemistry is the study of
`
`molecules and reactions of all elements as
`
`opposed to organic chemistry which is focused on
`
`the compounds of carbon.
`
` Q. Inorganic chemistry includes carbon?
`
` A. It can, yes.
`
` Q. Usually not?
`
` A. There's another branch called
`
`organometallic chemistry which covers the
`
`intersection of the two.
`
` The particular studies -- areas that I
`
`was involved in were materials for catalysis
`
`which is catalysis of organic reactions, so, in
`
`that regard, they also intersect.
`
` Q. Okay. And in your doctorate research
`
`you did a thesis?
`
` A. I did.
`
` Q. What did that involve?
`
` A. The topic?
`
` Q. Yeah.

`
` Q. That's okay. Just a general
`
`description is fine.
`
` A. I characterized inorganic materials,
`
`hydroxide, metal hydroxide materials and then
`
`used them for catalytic reactions.
`
` Q. What type of catalytic reactions?
`
` A. We were looking at halide replacement
`
`reactions, organic halides.
`
` Q. And how about your post-doctorate
`
`research?
`
` A. Post-doctorate research involved
`
`characterization of layered phosphate materials
`
`and phosphate-related materials.
`
` Q. Did that have an organic component to
`
`it?
`
` A. The phosphates were, yes, they had an
`
`organic -- they were organic phosphates.
`
`Phosphonates they are called.
`
` Q. And, briefly, since your post-doc I
`
`take it, then -- after your post-doc, you entered
`
`into -- so you left academia?

`
` A. Correct.
`
` Q. So describe just briefly your career
`
`in the industry.
`
` A. I first started with Texaco in their
`
`research labs in Beacon, New York, in
`
`synthesizing, characterizing catalysts, running
`
`organic reactions, using them, operation
`
`reactions.
`
` After that, I worked for a company
`
`called Nepera Chemicals. It's a pyridine
`
`manufacturer. In that position my main
`
`responsibility was for oxidation of pyridine
`
`derivatives, ammoxidation, actually, which
`
`involves ammonia as well as oxygen, and then
`
`since I've been at -- since I've been at ADM I've
`
`been mainly focused on our glycerol to propylene
`
`glycol plant which is just up the street here.
`
` That was -- that was under
`
`construction when I arrived, and I helped in
`
`getting the catalyst made for that, getting it
`
`commercialized and extensive testing in the lab
`
`of the reactions.

`
` Since then, I've also been involved in
`
`10
`
`a number of other projects.
`
` Q. For example?
`
` A. For example, sorbitol -- reactions of
`
`sorbitol which is a sugar derivative.
`
` I worked with the integrated
`
`biorefinery with a Department of Energy grant
`
`which involved sourcing corn stover, corn stalks,
`
`turning them into chemicals, so a lot of
`
`separations, hydrogenation, oxidation reactions.
`
` Q. And the education and work that you
`
`just described, did any of that involve the
`
`catalytic oxidation of heterocyclic aromatic
`
`compounds?
`
` A. All of my work at Nepera on
`
`ammoxidation of pyridine derivatives, since
`
`pyridine is a heterocyclic organic aromatic
`
`compound, the answer is I have pretty extensive
`
`experience in that.
`
` Q. And at ADM have you done work like
`
`that?
`
` A. I have not directly. I have not

`
` A. I've been -- I'm aware that they were
`
`going on in the building. As a manager no one --
`
`let me be careful. No one who reported to me was
`
`doing these.
`
` Q. Okay. So what are you aware of in
`
`regards to what's going on at ADM involving the
`
`catalytic oxidation of heterocyclic aromatic
`
`compounds? Even, for example, methods for the
`
`preparation of FDCA.
`
` MR. DOSHI: What's the question?
`
` MR. GLYNN: Dr. Martin had said that
`
`he was aware of certain work being done at ADM,
`
`and I'm now asking what he's aware of about this
`
`work, and just to make it more specific,
`
`specifically with regards to ADM's development of
`
`methods for preparing FDCA.
`
` MR. DOSHI: The question, I think,
`
`might implicate -- we can talk without him, with
`
`him. It's up to you. We need to get a
`
`protective order. I don't believe we have a

`
` MR. DOSHI: I'm not aware. I think it
`

`

`necessary, and we, of course, would support that.
`

`
` THE WITNESS: As you can read in the

`

`

`

`
`So there's work being done here on developments
`
`of methods for FDCA, that you're aware of?
`

`

`
` A. No.

` A. I don't know.
`
` Q. Okay.
`
` A. It was not a part of my

`
` Q. At some point over the past nine years
`

`

`

`
`that the claims in the patent are obvious, and
`
`I'm asking him questions that go to the
`
`non-obviousness of the claims in the patent.
`
` I don't see where that requires
`

`
` As far as getting documents and things
`
`like that that we have not done, I'm not
`
`requesting that we go get any documents.
`
` MR. DOSHI: Sure. But in his opinions
`
`he does not address the ADM process. He
`
`discusses publically-disclosed processes, and
`
`your questions are specific to ADM's confidential
`
`processes.
`
` MR. GLYNN: Well, my questions are

`

`
`additional discovery, at least in the conference
`
`call but did not raise thereafter, and I'm
`

`
` What paper is this?
`
` Proposed motions is what I'm reading
`
`from.
`
` MR. ENGLAND: Paper 14.
`
` MR. DOSHI: Paper 14.
`
`BY MR. GLYNN:
`
` Q. All right. While it's true that we
`
`did not seek additional discovery as far as
`
`seeking documents along these lines, I'm still
`
`simply asking Dr. Martin questions relating to
`
`secondary considerations.
`
` He opined on secondary considerations
`
`in his report. I don't intend to spend a lot of
`
`time on this, but I think our argument is taking
`
`up more time...

`
` At the time there was no way for me to

`-- well, actually, there was, but at the time --
`
`you know, he's an ADM employee. He's sitting
`
`right here. He's your expert, and he has
`
`knowledge of what ADM, at least generally, did to
`
`try to develop such a process which can go

`
`Right?
`
` A. Yes.
`
` Q. What's the nature of that partnership?
`
`Do you know?
`
` A. My understanding is that Dupont brings
`
`oxidation expertise to the table along with
`
`polymer, their polymer science, since it's
`
`ultimately intended to make a polymer.
`
` ADM brings a large source of
`
`carbohydrates and expertise in making HMF, HMF

`
` In the process of making FDCA from
`
`HMF, for example, and esters of HMF, there are a
`
`number of reaction conditions that can be varied
`
`that can -- that can ultimately affect yields.
`
`Right?
`
` A. Correct.
`
` Q. Okay. What kind of reaction
`
`conditions would be different that can affect the
`
`yield?
`
` A. Temperature, pressure, catalyst
`
`concentration, specific composition of the
`
`catalyst, HMF concentration, time of reaction.
`

`
` Q. Okay. Fine. All right. So let's
`
`start with temperature. How does temperature
`
`affect yield?
`
` A. In general, temperature affects
`
`conversion by increasing conversion. Temperature
`
`has an effect on yield through -- with a
`
`catalytic system through potentially changing
`
`mechanism, changing the pathway of reactions,
`
`changing the amount of ultimate product, final
`
`product that you generate as opposed to
`
`intermediates.
`
` Q. And it was your testimony that
`
`generally as temperature increases, yield
`
`increases?
`
` A. For situations in which at lower
`
`temperatures you see intermediate products.
`
` Q. Okay. So I would be incorrect in

`

`
`for making FDCA from HMF and esters of HMF.
`
` A. It's a question that you can't answer
`
`without consideration of all the other parameters
`
`that we've listed, because the effect changes.
`
` Q. Okay. Let's leave the other
`
`parameters for now constant and just talk about
`
`temperature, so I'm not changing other
`
`parameters.
`
` A. I don't think I can answer that if I
`
`don't have the details of what else is there.
`
` Q. Okay. And you said that temperature
`
`affects conversion. What does that mean?

`
` Okay. And you mentioned that the
`
`change in temperature could change the mechanism
`
`of the reaction. What did you mean by that?
`
` A. Change in temperature can affect
`
`the -- perhaps, mechanism was a misstatement.
`
`Can change the preferred pathway of the reaction.
`
` Q. Okay. And that you had mentioned as
`
`well the pathway, so...
`
` So in this context, the context of
`
`converting FDCA -- or converting HMF -- you know,
`
`let's just -- when I say HMF, you, of course,
`
`understand that to be 5-hydroxymethylfurfural,
`
`but we'll be mostly using the shorthand for HMF,
`
`so that won't be so bad, but that's
`
`5-hydroxymethylfurfural.
`
` When I say that, you know that I mean
`
`HMF?
`
` A. Yes.
`
` Q. Okay. And for FDCA, when I say that,
`
`you know that what I mean is
`
`2,5-furandicarboxylic acid?
`
` A. As I declared earlier, yes.

`
` Q. I just want to make sure. And at
`
`times that's also abbreviated in some of the art
`
`29
`
`as FDA?
`
` A. Correct.
`
` Q. So if we use any of those terms, we
`
`know they're interchangeable?
`
` A. Correct.
`
` Q. And so to the extent it comes up, I'll
`
`do a couple more.
`
` When I say AMF, that would be
`
`5-acetoxymethylfurfural?
`
` A. Correct.
`
` Q. Did I say that correct? And that's an
`
`ester of HMF?
`
` A. Acetic acid ester of HMF.
`
` Q. And -- okay. If we run across any
`
`other ones, we'll make sure we clarify what the
`
`abbreviations are.
`
` All right. So where was I?
`
` Oh, pathway, so you said the
`
`temperature can change the pathway. What do you
`
`mean?
