`
` EXAMINATION
`
`BY MR. SCHWENTKER:
`
` Q Good morning. Sorry about the noise.
`
`My name is Andy Schwentker. I'm from the law firm
`
`Fish & Richardson in Washington, D.C.
`
` Could you please state your name.
`
` A My name is Godmar Back. First name
`
`is spelled G-O-D-M-A-R, Godmar.
`
` Q And how do you like to pronounce your
`
`last name?
`
` A Back.
`
` Q I understand you have been deposed
`
`before so I won't waste a lot of time going over
`
`ground rules. But if you don't understand a
`
`question please let me know and I'll try to rephrase
`
`it. And if you need a break please let me know and

`
` A It does.
`
` Q And you are still a professor at
`
`Virginia Tech?
`
` A I am, yes.
`
` Q And did you do anything to prepare
`
`for your deposition today?
`
` A I did. I reread the declarations I
`
`have submitted in this case, among others.
`
` Q And what do you mean by among others?
`
`Are you referring to other declarations or other
`
`documents?
`
` MR. EDELL: This is Joe Edell from
`
` Fisch Sigler on behalf of the Patent Owner,
`
` Realtime Data. I want to caution Doctor
`
` Back to not reveal any conversations you
`
` had amongst counsel, but you can answer the
`
` question by identifying documents you
`
` recall that you reviewed in order to answer
`
` Mr. Schwentker's question.
`
` THE WITNESS: Yes, I reviewed and
`
` reread additional documents, such as the

`

`
` Q And by the patent in question, are
`
`you referring to U.S. Patent Number 8,880,862?
`
` A I think that's correct, the '862
`
`patent.
`
` Q Okay. So if we talk about the '862
`
`patent, you'll know what I'm referring to?
`
` A I do.
`
` Q And you understand the Realtime Data,
`
`LLC, claims to be the owner of the '862 patent?
`
` MR. EDELL: Objection, form.
`
`BY MR. SCHWENTKER:
`
` Q Is that correct?
`
` A I am not certain about the legal
`
`aspects of this, but I think this is the name that
`
`appears on the patent.
`
` Q If I refer to Realtime Data, LLC, as
`
`Patent Owner, will you understand who I'm referring
`
`to?

`
`BY MR. SCHWENTKER:
`
` Q Doctor Back, the court reporter has
`
`handed you what's been marked as Exhibit 1. It's
`
`also identified as Apple 1001. And do you see that
`
`this is U.S. Patent Number 8,880,862?
`
` A Yes, that's what it appears to be.
`
` Q That's the '862 patent you were
`
`referring to before?
`
` A Yes, it is.
`
` (Deposition Exhibits 2-5 were marked
`
` for identification.)
`
`BY MR. SCHWENTKER:
`
` Q I wanted to go ahead and introduce
`
`several of the documents we're going to be talking
`
`about today. So the court reporter has handed you
`
`Exhibit -- a document marked as Exhibit 2, which is
`
`Patent Owner's Motion to Amend in Case
`
`IPR2016-01737. Do you see that?
`
` A I see on the front page it says

`

`
` caution you just answer yes or no.
`
` THE WITNESS: Would it be possible to
`
` look at the declaration that I've
`
` submitted?
`
`BY MR. SCHWENTKER:
`
` Q Sure. Yeah, we'll get to that in
`
`just --
`
` A Okay. I think I did. Yes, I did
`
`review this Patent Owner's Motion to Amend.
`
` Q And if you could turn to, after page
`
`26, there's a page marked "i" that has the title
`
`Claimed Appendix at the top.
`
` A I see that.
`
` Q And it goes through page xii?
`
` A Yeah, I see that.

`
`referring to?
`
` MR. EDELL: Objection, form.
`
` THE WITNESS: I think these pages
`
` list the amended claims that are part of
`
` this -- of the 1737 Motion to Amend.
`
`BY MR. SCHWENTKER:
`
` Q Okay. And you reviewed those for
`

`
` A Yes, I did.
`
` Q Okay, great.
`
` Let's turn to the next exhibit, which
`

`
`case IPR2016-01738, and it's another Patent Owner's
`
`Motion to Amend. Do you see that?
`
` A I see that the front page says Patent
`
`Owner's Motion to Amend, and the number ends in
`
`1738.

`
` motion.

`
` Q And again, after page 22 there's a
`
`claims appendix on page i through xi. Do you see
`
`that?
`
` A I do see that.
`
` Q And are those the amended claims in
`
`the 1738 proceeding that you reviewed in preparing
`
`for your deposition?
`
` MR. EDELL: Objection, form.
`
` THE WITNESS: I think those are the
`
` amended claims at issue in the 1738.
`
`BY MR. SCHWENTKER:
`
` Q And just to make sure we're on the
`
`same page, you've referred to the 1737 and 1738
`
`proceedings. If we talk about those two
`
`proceedings, will you understand that we're
`

`

`

`

`
`Support of the Patent Owner's Reply to its Motion to
`

`
` A Yes, this is my Declaration in

`
`Amend.

`
` A In the 1737, correct.

`
` A Yes, I did.

`

`

`
`incorrect, although I discovered a typo on page 6.
`
`I misspelled "according". There should be 2 c's. I
`
`apologize.
`
` Q That's the only error you noticed
`

`declaration that I have submitted earlier in support
`

`
`document I have reviewed in preparation for today.

`

`

`
` that this deposition was about.
`
`BY MR. SCHWENTKER:
`
` Q Okay. But you did write this
`
`declaration, correct?
`
` A I did.

`

`
` says in this paragraph.
`
`BY MR. SCHWENTKER:
`
` Q Can you tell me which materials you
`
`reviewed before signing this declaration?
`
` A So as I stated in the declaration, I
`
`reviewed and considered the materials identified in
`
`the paragraph above. That's paragraph 2, and that
`
`includes the Doctor Neuhauser's declaration, Exhibit
`
`1030, the cross-examination testimony, the reply in
`
`support of the Patent Owner's motion, and then there
`
`was mentioned in the remainder of this paragraph.
`
` Q Okay. Did you -- did the materials
`
`you reviewed and considered include the '862 patent?
`
` A So in this declaration I was asked to
`
`address the task whether the proposed amended claims
`
`find support in the specification of the '862
`
`patent, and so I reviewed the specification of the
`
`'862 patent in order to answer this question.
`
` Q And did the materials you reviewed
`
`include the references identified in Patent Owner's

`
` THE WITNESS: Could you clarify
`
` specifically which references you're
`
` referring to that's in the 1737 Motion to
`
` Amend?
`
`BY MR. SCHWENTKER:
`
` Q Yes. So referring to Exhibit 2,
`
`which is the Patent Owner's Motion to Amend in the
`
`1737 Proceeding, do you understand that this motion
`
`to amend identifies certain references?
`
` MR. EDELL: Objection, form.
`
` THE WITNESS: Again, could you be
`
` more clear about are you referring to
`
` Petitioner's references or references that
`
` appear in the motion to amend? Which
`
` specific references is your question about?

`
` Q If you could turn to page 19 of the

`
`as well. It says: The Petitioner in this

`
`Sukegawa, Dye, Settsu, Burrows and Zwiegincew.
`

`

`

`
` MR. EDELL: Objection, form.
`
` THE WITNESS: So those are the
`
` references that I considered -- may have
`
` considered in the declaration I submitted
`
` in support of the motion to amend, but I
`
` don't think I'm stating this in the
`

`
`to which it claims priority: U.S. Patents 6,539,456,
`

`
`Dye, 6,434,695, which is called Esfahani, and 603 --
`
`excuse me, 6,073,232, and we just call it Kroeker.
`
` Do you see that?
`
` A I see where that has spelled out.
`
` Q Have you reviewed the Stewart, Dye,
`
`Esfahani, and Kroeker references identified here?
`
` MR. EDELL: Objection, form.
`
` THE WITNESS: So I have reviewed them
`
` to the extent to answer the question
`
` whether the proposed amended claims in the
`
` 1737 and 1738 proceedings are patentable
`
` over these references.

`
` about the same amended claims.
`
`BY MR. SCHWENTKER:
`

`
`"preload", which of the amended claims use the word

`

`
` do.

`
`2 and 3?
`
` A You are talking about the 1737 or 38?
`
` Q Both.
`
` A So the 1737 Amended Claim 118 uses
`
`the claim terms "preloading" and "preloaded." So
`
`does Amended Claim 122. As does Amended Claim 124.
`
`The term also appears in Claim 133. The term
`
`appears in Claim 145. Also in 157.
`
` So those appear to be the occurrences
`
`in the 1737. I'm now looking at the 1738.
`
` Q Before you turn to 1738, let me ask
`
`one follow-up question about 1737. I believe you
`
`identified all of the independent amended claims; is
`
`that correct?
`
` MR. EDELL: Objection, form.
`
` THE WITNESS: So I am not certain if
`
` the term "preloading" or "preloaded" occurs
`
` only in the independent claims or also
`
` dependent claims. I am not certain. I
`
` would have to carefully check.

`
`the independent amended claims. Is that accurate?
`
` MR. EDELL: Objection, form.
`
` THE WITNESS: My understanding is
`
` certain independent claims at issue in the
`
` 1737. This is 118 is one of them, it does
`
` appear there. And 122 I believe is also an
`
` independent claim, and it appears there as
`
` well. Claim 124 is also independent claim,
`
` and it appears there as well.
`
` But here Claim 133 is dependent
`
` claim; it appears there as well.
`
`BY MR. SCHWENTKER:
`
` Q Okay. So it appears in -- the word
`
`"preloading" or "preloaded" appears in at least one
`
`dependent claim, but it also appears in all of the
`
`independent amended claims; is that correct?
`
` MR. EDELL: objection, form.
`
` THE WITNESS: It -- it appears in at
`
` least one dependent claim and it appears to
`
` appear in all the independent claims that
`
` are at issue in the 1737.

`
`that you just did for the 1737.
`
` A Okay. So I'm going to talk about
`
`dependent and independent. Claim 174 is an
`
`independent claim and it includes the term
`
`"preloading". Claim 177 -- or Amended Claim 177 is
`
`an independent claim and it includes the term
`
`"preloading". Amended Claim 179 is an independent
`
`claim and it includes the term. Claim 196 is a
`
`dependent claim and it includes the term
`
`"preloaded". And I think that's it. So all the
`
`independent claim and at least some dependent claims
`
`include that term.
`
` Q Okay, great. Thank you.
`
` A Amended claims.
`
` Q Yes, thank you.
`
