`the enclosed volume that contains the water that's
`to be supplied to the pump.
`Q Does a water reservoir have to be formed
`from a single piece of metal?
`A Does a reservoir have to be formed from a
`single piece of metal? Not necessarily, no.
`Q Could a water reservoir be formed from being
`welded?
`A A water reservoir can be formed by a welded
`structure, yes.
`Q Can something be mounted by a welding?
`A Welding is a way to mount, yes.
`Q Dr. Giles, let's turn to the first -- well,
`I'll call it the second of your reports, your
`rebuttal expert report of Dr. Durham K. Giles that
`we premarked as Exhibit 264.
` (Marked Exhibit 264.)
`BY MR. MAYS:
`Q Dr. Giles, does Exhibit 264 appear to you to
`be your complete rebuttal expert report?
`A It appears to be, yes. It's many pages, so

`
`does appear to be the report.
`Q And, Dr. Giles, does your rebuttal report
`contain your complete response to the opinions in
`Dr. Sorini's opening report?
`A I believe so, yes. There was one report
`that had an errata that was filed later.
`Q Understood with the errata.
`A Yeah.
`Q Is there anything -- is there anything --
`let me back up.
` You reviewed the reply expert report of
`Dr. Sorini, correct?
`A I did.
`Q Having reviewed the reply expert report of
`Dr. Sorini, are there any changes or amendments you
`would make to the opinions in your rebuttal expert
`report?
`A Not at this time, no.
`Q Now, Dr. Giles, just flipping through the
`table of contents, I don't see any reference here to
`the concept of the objective indicia of
`nonobviousness.

` Is it correct that in your rebuttal report,
`you offered no opinions on objective indicia of
`nonobviousness?
`A Ask me that again.
`Q Sure.
`A Yeah.
`Q Let me ask it a little bit more
`straightforward.
`A Yeah.
`Q Would you agree with me that in your
`rebuttal expert report you did not offer any
`opinions regarding the objective indicia of
`nonobviousness for the '618 patent?
`A That's my recollection, yes.
`Q Let's start with the section about your
`qualifications, Dr. Giles, which I believe --
`starting at page 3 of your rebuttal report.
` My first question for you is, Dr. Giles, do
`you speak German?
`A I do not speak German, no.
`Q You understand that the source code for the
`accused products in this case was written in German?

`
`A That's my understanding, yes.
`Q In paragraph 10 of your rebuttal report, you
`reference getting a Bachelor of Science degree in
`agricultural engineering from the University of
`Georgia.
` What was the coursework that you took for
`your agricultural engineering degree?
`A Do you mean -- coursework in what -- it's an
`accredited engineering program, so it's a standard
`engineering background.
` Should I list the courses or --
`Q Well, I guess my question at more of a high
`level is, what is the focus of an agricultural
`engineering degree from the University of Georgia?
`A The focus of agricultural engineering
`degrees is an application of mechanical, electrical,
`and in some cases elements of civil engineering for
`the specific generalized industry of agriculture.
` And specific classes you would take would be
`machine design, control systems and theory,
`structure, strength of materials, fluid mechanics,
`heat transfer, thermodynamics, power transmission,

`section, what appears to be substantially upright on
`the left, that portion of the frame, there's a void
`essentially inside that square part or rectangular
`opening at the top, and there's a void inside there.
`Q And when you say the rectangular part,
`you're referring to this rectangular part that's
`two-thirds of the way up from the photograph?
`A Yeah. It appears to be like a flange
`connection.
`Q Now, just to the right of that rectangular
`void, I see what appears to be weld marks welding
`one piece of metal with a rectangular void to
`another piece of metal.
` Do you see that?
`A I do.
`Q So you would agree with me that this water
`reservoir that you've described as being here,
`that's welded to the frame, correct?
`A No, I do not agree with that statement.
`Q Why not?
`A The way you described it, you said there's a
`reservoir welded to the frame. In fact, the frame

`is welded and created, and the reservoir is integral
`to that frame.
`Q What do you mean by integral to the frame?
`A It's not a separate component that can be
`removed and replaced.
`Q The portion of the reservoir that you say is
`integral to the frame, that portion has been welded
`to the other components of the frame, correct?
`A The frame has been welded together in a
`manner that results in a reservoir being created.
`Q Let's turn to page 103 of your rebuttal
`report -- actually, page 104.
` On page 104, you have what appears to be a
`couple CAD schematics. On the previous page, you
`say, The unitized construction is further shown by
`the images from the CAD model of the frame below.
` Do you see that?
`A I do.
`Q And how did you -- or let me back up.
` Did you create the images that we see on
`page 104 of your rebuttal report?

`is, no, these images were supplied to me.
`Q Your understanding is that these images were
`created from CAD schematics, correct?
`A Yes. I have visualized the CAD program
`rotating and displaying these views.
`Q When did you first have access to those --
`CAD program?
`A I don't have direct access to the CAD
`program. These images were supplied to me after the
`site visit.
`Q So you've never personally had access to the
`CAD program that was used to generate these images?
`A I have not accessed the CAD program
`directly. There may have been access provided to me
`that I didn't use, but I haven't directly accessed
`it.
`Q What steps did you take to confirm that
`these CAD schematics accurately depict the
`construction of a W 210 Fi machine?
`A My -- I did not take independent steps, but
`I asked for -- suggested that a CAD depiction would
`be very useful in communicating the design and

`
`integration of the reservoir and the frame.
`Q And did you take any steps to perform -- to
`confirm that these images depicted W 210 Fi as
`opposed to a W 210 i machine?
`A I did not confirm independently. The short
`answer is no; the longer answer is I didn't confirm
`independently that these specific images were from a
`specific machine model.
`Q And when you say the -- when you say that
`the images on page 104 of your rebuttal report were
`supplied to you, who supplied them to you?
`A Those came from counsel.
`Q Are you able to state whether the CAD
`program that was used to generate these images
`identifies any part as the frame?
`A Okay. Can you please ask me that again?
`Q Yeah.
` So in the CAD program that was used to
`generate these diagrams, do you know if there is any
`part specifically labeled frame?
`A In the CAD program, the parts, as I recall,
`were not labeled in the rotational view and the

`definition of efficient water management. But the
`performance tracker system does adjust the number of
`spray bar sections that are turned on relative to
`the milling width.
`Q What does the '618 patent say about
`adjusting spray sections of a spray bar for the
`water spray width?
`A The '618 patent, as I recall, is silent on
`adjusting for widths -- no, there are two spray
`banks there. The spray bank is controlled by a
`single valve.
`Q So on page 31, it says, Four separate
`electrically switchable segments of the water spray
`bar allow the optimum quantity of water to be added.
` Do you see that?
`A I do.
`Q And what does the '618 patent say about four
`separate electrically switchable segments?
`A I believe it's silent as to individually
`switchable segments of a spray bar.
`Q You can put that one down.

`and if we take a look -- let me know when you've got
`it. We're going to go to page 2.
`A I'm on page 2.
`Q And then do you remember when Mr. Mays was
`asking you questions with respect to your Grounds 2
`and 5 where it lists Anderton/Orr?
`A Yes.
`Q Let's take a look at -- just make sure this
`is the right spot -- paragraph 58 of your opening
`report on page 37.
`A Yes.
`Q Could you read paragraph 58 into the record,
`the first sentence?
`A U.S. Patent Publication 2011/0160920 A1 to
`Orr, et al., which published in June 2011 with Bates
`Number WA-0032800, Orr, incorporates by reference
`the teachings of Anderton, which describes two
`examples of valve configurations for activating
`spray heads.

`incorporation by reference?

`referencing those teachings, that we're including
`that in that paragraph.
`Q Now, do you remember earlier when Mr. Mays
`was asking you some questions regarding the water
`tank of the accused Wirtgen machines?
`A I do, in general, yes.
`Q And what was your opinion regarding whether
`the accused Wirtgen machines included a water
`reservoir mounted on the frame?
`A My opinion is the accused machines have a
`water reservoir that is integrally part of the
`frame.
`Q And what was your basis for your opinion
`that the accused Wirtgen machines have a water
`reservoir that is integrally part of the frame?
`A It's not denoted anywhere, either visually
`in the inspection or in the parts manual documents,
`Wirtgen has a separate component that can be
`purchased or with a separate part number or a
`call-out.
`Q Anything else?
`A And it is visually a void in the frame. If

`view of the machine for the fluid system and the
`parts listing by parts numbers and call-outs, there
`was no water tank as a separate item.
`BY MR. OGDEN:
`Q Can you tell the jury what portions of the
`parts manual you're referencing that helped inform
`that opinion?
` MR. MAYS: Same objection.
` THE WITNESS: I can find it. The copy
`that I had was a searchable PDF, which greatly
`accelerated the process.
`BY MR. OGDEN:
`Q Is there one on this computer?
`A Let's see. That may be helpful.
`Q There may or may not be. I'm not sure. The
`password is that down there.
`A All I see are reports here, so I don't think
`we have -- oh, well, yes, we do, the very last item.
`I'm still looking. I'm getting close.
` Yeah, we look on -- for example, it's
`0027222, which I believe is page 671 of the 800-page
`document.

`Q The one that ends in Bates Number 27222?
`A Yes.
`Q Okay.
`A So starting there, we see the spare parts
`drawing as water tank. And you see the individual
`components there are only the connection parts.
` If you go to the following page, which would
`be 223, and we look at all the call-outs for the
`reference numbers and part numbers, there's no tank
`there. It's not an item that you can replace or
`acquire as an individual and distinct unit.
`Q Okay.
`A And there's no -- in the 222 drawing,
`there's no, you know, specific call-out for water
`tank.
`Q And then can you take a look at the page
`ending in 230.
`A 230? Yeah. Stand by.
` MR. MAYS: I'll object to the line of
`questioning as outside the scope of his rebuttal
`report.
` THE WITNESS: Yes, I'm on 230.

`Q And how does that image relate to the image
`that you just pointed the jury to?
` MR. MAYS: Same objection, outside the
`scope of his report.
` THE WITNESS: It is a different view
`from a different perspective of the machine. This
`is entitled Water Pump Drive, but it shows simply
`the connections, the -- primarily, the hydraulic
`connections to the water pump. And, again, there's
`no tank called out or denoted explicitly.
`BY MR. OGDEN:
`Q And do you remember when -- if we take a
`look back at your initial -- sorry, your rebuttal
`report, and let's take a look at page --
`A Is that Exhibit 265? 265?
`Q No, your opening.
`A Oh, opening?
`Q Yeah.
`A Yeah, we're back on that, 263, yes.
`Q You have to give me a second now. Oh, okay.

`A Yes.
`Q And how does that relate to what you just
`showed us in the spare parts manual?
` MR. MAYS: Objection, outside the
`scope.
` THE WITNESS: For example, in looking
`at a document that ends in 230, as we look at this,
`we are effectively looking at -- we're looking from
`the top left corner of the computer into this
`figure.
`BY MR. OGDEN:
`Q Okay.
`A You see the weldment on the left side, and
`then you'll see -- there's a hydraulic line 8 and a
`dash line. And where that dash line intersects the
`frame -- I'm simply using the dash line as a visual
`reference, not implying any mechanical connection.
` Where that dash line comes into the frame,
`that is the square opening that you see on the
`photograph.

`spare parts manual with respect to this claim
`element?
`A What led me to that was a desire to
`understand aspects of the machine that were
`difficult, if not impossible, to see in the visual
`inspection.
`Q Okay.
`A I wasn't able to saw the machine in half
`obviously in the visual inspection. And the ability
`to look at this and to see how other components
`would be associated with the reservoir, for example,
`the pressure sensor for the tank level, other
`aspects of the components that are associated with
`the tank.
`Q Well, why were you looking at the pressure
`sensor for the tank level?
` MR. MAYS: Objection, outside the
`scope.
` THE WITNESS: That was of interest in
`statements made by Dr. Sorini about he noted a
`change in the level indication when he added water.
`And it was just for me to confirm in my thinking how

`A Which document?
`Q What's the exhibit number on this most

` MR. OGDEN: The huge one.
` MR. MAYS: The huge one, is it --
` THE WITNESS: The parts manual?
`BY MR. MAYS:
`Q Yeah.
` Is it 283?
` MR. OGDEN: I've forgotten now.
` THE WITNESS: 284.

`A I don't believe I did, no.
`Q And nowhere in your report did you cite the
`Bates Number Page WA-0027230, correct?
`A I don't believe I explicitly refer to it,
`no.
`Q And let's turn back to your opening -- I'm
`sorry, your rebuttal report, page 99.
`A Yes.
`Q And there's no reference in paragraphs 134,
`135 to a spare parts manual, correct?
`A Not in these paragraphs, no.
`Q And if you turn to the next page, there's no
`reference in paragraphs 136 or 137 to a spare parts
`manual, correct?

`with regards to your opinions in the section
`entitled, The water reservoir is not mounted on the
`frame because the water reservoir is formed in the
`frame, you offered no opinions regarding the spare
`parts manual until today, correct?
`A Explicitly that's correct, yes.
