`
`INTRODUCTION
`
`Pursuant to the Board’s authorization on June 4, 2014 and the Office Trial
`
`Practice Guide, 77 Fed. Reg. 48767-68 (Aug. 14, 2012), Petitioner Sipnet EU
`
`S.R.O. respectfully submits the following responses to the observations submitted
`
`by the Patent Owner regarding the May 29, 2014 cross—examination of Petitioner’s
`
`declarant Vadim Antonov.
`
`RESPONSES TO PATENT OWNER’S OBSERVATIONS
`
`A.
`
`Response to Observations 1, 2 and 3
`
`In response to Patent Owner’s Observations 1, 2 and 3 and specifically that
`
`“Mr. Antonov’s Anticipation Opinions Were Based On The Combination of
`
`Multiple References”, “Mr. Antonov Rendered Anticipation Opinions Based On
`
`Multiple Sources That Are Not Of Record In This Proceeding” and “Mr. Antonov
`
`Relied on a Product To Form His Opinions,” Petitioner respectfully notes that in
`
`Exhibit 2045, on Page 21, Lines 8-17; Page 28, Line 21 through Page 29, Line 3;
`
`Page 30, Line 13, through Page 31, Line 6; Page 31, Lines 16-24 and Page 32, Line
`
`23 through Page 33, Line 19, Mr. Antonov testified that:
`
`Ex. 2045, Page 21, Lines 8-17
`
`8
`
`Q. Where in your declaration do you
`
`9 demonstrate that each and every claim element is
`
`10 rendered invalid by a piece of prior art?
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`11
`
`A. This is described in subsequent sections,
`
`12 and basically every section discusses a specific
`
`13 claim made. And in the patent, in the original
`
`14 '704 patent, or in declaration of expert witness,
`
`15 Mr. Mayer—Patel, if I remember the name correctly,
`
`16 and other of those claims. So the entirety of that
`
`17 document is basically the answer.
`
`Ex. 2045, Page 28, Line 21 through Page 29, Line 3
`
`21
`
`A. Not only that. By "obvious," I mean
`
`22 obvious at that specific time in history, because
`
`23 obvious —— what was obvious —— what is obvious now
`
`24 is not the same as what was obvious 20 years ago.
`
`25
`
`So I made an effort to understand and
`
`0029
`
`1
`
`recall the state of the art at the time which is
`
`2 relevant to discuss obviousness of this specific
`
`3 patent.
`
`Ex. 2045, Page 30, Line 13 through Page 31, Line 6
`
`13
`
`Q. Soto confirm --
`
`14
`
`A. Yes.
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`15
`
`16
`
`Q.
`
`—— is that you do not provide an opinion
`
`with respect to whether or not any of the claims
`
`17
`
`are obvious, is that correct?
`
`18
`
`19
`
`20
`
`21
`
`22
`
`23
`
`24
`
`25
`
`A. I'm confused by legal usage of that term.
`
`What I'm saying is that my declaration, all of it
`
`depends on things being already known or
`
`implemented by previous published documents or
`
`products, and it didn't actually require any new
`
`ideas or new things which would be not trivial.
`
`For example, I consider substitution of
`
`terms calling the same thing by different names to
`
`0031
`
`1
`
`2
`
`be trivial. And I find that a significant portion
`
`of Mr. Mayer—Patel's declaration essentially
`
`depends on making distinctions of —— by using terms
`
`which mean exactly same thing. So terms means same
`
`thing. He makes distinction saying that they're
`
`different things, which I consider to be incorrect.
`
`Ex. 2045, Page 31, Lines 16-24:
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`16
`
`Q. You do not provide an opinion in your
`
`17 declaration that any of the claims are rendered
`
`18 obvious by the prior art, is that correct?
`
`19
`
`A. The foundation of my argument is that
`
`20 everything is anticipated to the extent that
`
`21 translation between prior existing art to what is
`
`22 in the '704 patent is obvious and trivial. So
`
`23 somebody skilled in this profession would
`
`24 understand that they mean exactly same thing.
`
`Ex. 2045, Page 32, Line 23 through Page 33, Line 19
`
`Q. In your summary of opinions --
`
`A. Uh—huh (affirmative).
`
`Q.
`
`—— you only identify an opinion that the
`
`23
`
`24
`
`25
`
`0033
`
`1 claims at issue are anticipated.
`
`2
`
`3
`
`A. Yes.
`
`MR. MORLOCK: Objection, asked and
`
`4 answered.
`
`5
`
`6
`
`MR. HOFFMAN:
`
`Q. You do not --
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`7
`
`8
`
`Excuse me, Counsel.
`
`And do you not provide an opinion that the
`
`9 claims at issue are obvious.
`
`10
`
`MR. MORLOCK: Objection, asked and
`
`11
`
`answered.
`
`12
`
`13
`
`14
`
`MR. HOFFMAN:
`
`Q. You can answer the question.
`
`A. Okay. Again, what I claimed, that
`
`15 everything was anticipated, and that terminological
`
`16 difference is that —— the fact that its only
`
`17 terminological difference is, on its own, obvious.
`
`18 So a practitioner in the art would know that those
`
`19 different terms mean the same thing.
`
`The above testimony is relevant to (1) Exhibit 1023, the Antonov
`
`Declaration; and (2) Paper No. 33, the Petitioner’s Reply. The above testimony is
`
`relevant because it explains that the Antonov Declaration was provided from the
`
`perspective of a technical expert (not a patent lawyer) who based his conclusions
`
`from the point of view of a person skilled in the art.
`
`B.
`
`Response to Observation 4
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`In response to Patent Owner’s Observation 4 and specifically that “Mr.
`
`Antonov Stated That NetBIOS Does Not Disclose Dynamic Addressing,”
`
`Petitioner respectfully notes that in Exhibit 2045, on Page 134, Line 12 through
`
`Page 135, Line 5, Mr. Antonov testified that:
`
`Ex. 2045, Page 134, Line 12 through Page 135, Line 5
`
`12
`
`Q. But the document itself, the NetBIOS
`
`13 document itself, doesn't specifically disclose the
`
`14 idea of dynamic addresses.
`
`15
`
`A. No, it doesn't. And, again, the fact that
`
`16 it doesn't, it means precisely that it will work
`
`17 with —— is that it is designed to work with any
`
`18 method, that NetBIOS —— operation of NetBIOS is not
`
`19 affected in any way by network of address
`
`20 assignment.
`
`21
`
`22
`
`Q. Does WINS disclose dynamic addressing?
`
`A. I know that with WINS software, as it is
`
`23 implemented, works with dynamic addresses. I am
`
`24 sure —— with dynamically assigned addresses. I do
`
`25 not recall if this is explicitly mentioned in the
`
`0135
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`1 document attached as an exhibit. But We need to
`
`2 understand that, as a document, WINS document
`
`3 attached to exhibit is essentially a user manual.
`
`4 It doesn't go into detail about what is exactly
`
`5
`
`inside. The actual software works.
`
`The above testimony is relevant to (1) Exhibit 1023, the Antonov
`
`Declaration; and (2) Paper No. 33, the Petitioner’s Reply. The above testimony
`
`regarding NetBIOS is relevant because it clearly demonstrates Mr. Antonov’s
`
`candid and unbiased perspective.
`
`C.
`
`Response to Observation 5
`
`In response to Patent Owner’s Observation 5 and specifically that “Mr.
`
`Antonov Testified That He Did Not Provide An Obviousness Opinion,” Petitioner
`
`respectfully notes that in Exhibit 2045, on Page 32, Lines 8-20, Mr. Antonov
`
`testified that:
`
`Ex. 2045, Page 32, Lines 8-20
`
`8
`
`Q. So your declaration with respect to your
`
`9 opinions in this matter are limited —— let me start
`
`10 again.
`
`11
`
`Your declaration —— your opinions in this
`
`12 declaration are limited to an opinion that the
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`13 claims at issue are anticipated by the prior art,
`
`14 is that correct?
`
`15
`
`A. Yes, that is correct. But —— yeah, that
`
`16 is substantially correct, plus I wanted to state
`
`17 that the differences between anticipated art and
`
`18 what is described in patent are mostly in —— are
`
`19 terminological and not substantial, and that is
`
`20 obvious.
`
`The above testimony is relevant to (1) Exhibit 1023, the Antonov
`
`Declaration; and (2) Paper No. 33, the Petitioner’s Reply. The above testimony is
`
`relevant because it clearly demonstrates that, contrary to Patent Owner’s
`
`observation, Mr. Antonov testified that he did consider obviousness in forming his
`
`opinion.
`
`D.
`
`Response to Observation 6
`
`In response to Patent Owner’s Observation 6 and specifically that “Mr.
`
`Antonov Testified That A Response To A Query In NetBIOS Indicates Only A
`
`“Willingness” To Accept Communication Rather Than Availability For
`
`Communication,” Petitioner respectfiilly notes that in Exhibit 2045, on Page 63,
`
`Line 2 through Page 64, Line 7, Mr. Antonov testified that:
`
`Ex. 2045, Page 63, Line 2 through Page 64, Line 7
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`2
`
`Q. Well, what about an idea of it being sort
`
`3
`
`of relatively current?
`
`A. Ah, now we're talking. Relatively current
`
`means that you want to be able to tell that a party
`
`was willing to accept your communication, and
`
`here's acknowledge to be within some predefined
`
`time period, relatively current.
`
`So you want to know, for example, that
`
`within the last five minutes it was willing to
`
`accept communications. That is the common practice
`
`in the field, is to achieve that effect by having
`
`either —— the party accepting communication to send
`
`you periodic updates, saying I am willing, I am
`
`willing, I am willing, and if you don't hear those
`
`updates, let's say, that party is no longer
`
`willing. Or to periodically ask that party are you
`
`still willing, are you still willing, are you still
`
`10
`
`11
`
`12
`
`13
`
`14
`
`15
`
`16
`
`17
`
`18
`
`19
`
`willing.
`
`20
`
`21
`
`That time period between those periodical
`
`updates is essentially your time guarantee of
`
`10
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`22 freshness of that data. In ‘704, there is a
`
`23 mention of timeout in claim 3, and timestamps,
`
`24 which I take to mean using time since previous
`
`25 status update to indicate the current on—line
`
`0064
`
`1
`
`status.
`
`2
`
`In NetBIOS we have exactly same mechanism,
`
`3
`
`specified in a lot more detail, including which
`
`4 messages to exchange and what format of messages is
`
`5 used, to do essentially the same thing, to
`
`6 periodically check if the other side is still
`
`7 registered or on—line, which is the same.
`
`The above testimony is relevant to (1) Exhibit 1023, the Antonov
`
`Declaration; and (2) Paper No. 33, the Petitioner’s Reply. The above testimony is
`
`relevant because it clearly demonstrates that Mr. Antonov testified that NetBIOS
`
`and the ‘704 Patent disclose the same mechanism to indicate availability for
`
`communication.
`
`E.
`
`Response to Observation 7
`
`In response to Patent Owner’s Observation 7 and specifically that “Mr.
`
`Antonov Did Not Render His Own Opinion on Claim Construction,” Petitioner
`
`ll
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`respectfully notes that in Exhibit 2045, on Page 65, Lines 13-23, Mr. Antonov
`
`testified that:
`
`Ex. 2045, Page 65, Lines 13-23
`
`13
`
`Q. Right. And, then, but there has to be a
`
`14 separate —— in C, a separate determination of
`
`15 positive on—line status, correct?
`
`16
`
`A. Again, positive on—line status, you cannot
`
`17 guarantee that the other party is —— will accept
`
`18 your communication for the reasons we already
`
`19 discussed. So positive determination of on—line
`
`20 status, I take that to mean positive determination
`
`21 of willingness —— of declared willingness of the
`
`22 other party to accept the communication, not as a
`
`23 guarantee that it will accept communications.
`
`The above testimony is relevant to (1) Exhibit 1023, the Antonov
`
`Declaration; and (2) Paper No. 33, the Petitioner’s Reply. The above testimony
`
`directly contradicts Patent Owner’s observation and is relevant because it
`
`demonstrates that Mr. Antonov clearly expressed his opinion on the meaning of the
`
`term “on—line.”
`
`B.
`
`Response to Observation 8
`
`12
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`In response to Patent Owner’s Observation 8 and specifically that “Mr.
`
`Antonov’s Testimony Offered a New Characterization of the Patent,” Petitioner
`
`respectfully notes that in Exhibit 2045, on Page 47, Line 19 through Page 49, Line
`
`7, Mr. Antonov testified that:
`
`EX. 2045, Page 47, Line 19 through Page 49, Line 7
`
`19
`
`A. Okay. Let me orient myself to what the
`
`20 first process means here. Ah, the first process
`
`21 here means the name server.
`
`22
`
`Is it correct? Is my understanding
`
`23 correct?
`
`24 Q. Are you saying the first process here,
`
`25 your equivalent —— you're saying the first process
`
`0048
`
`1
`
`is named by the name server?
`
`2 Is that what you're saying?
`
`3
`
`A. Yeah, what I'm saying is that first
`
`4 process in this claim is the same as network server
`
`5
`
`in technical language of NetBIOS documents,
`
`6 technical. First process is legal language because
`
`7 that doesn't provide specific technical term.
`
`13
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`8 Technical documents will refer to specific things
`
`9 by their function. Like name server keeps track of
`
`10
`
`names.
`
`11
`
`12
`
`13
`
`14
`
`15
`
`So I prefer to use technical language,
`
`obviously. So first process is a name server, and
`
`second process is general server process which
`
`could be used to establish communication to, like,
`
`a party which can be called or a party which can be
`
`16
`
`connected to.
`
`17
`
`18
`
`19
`
`Q. All right. Let's just make sure I
`
`understand your opinions. The first process
`
`referred to in claim 2 you’re saying is a server,
`
`20
`
`correct?
`
`21
`
`22
`
`A. Okay. A server is any persistent process
`
`which is used to answer questions or to accept
`
`23
`
`connections. And client is —— in technical terms,
`
`24
`
`client is a party which initiates connections or
`
`25
`
`send the questions up to the server.
`
`0049
`
`1 So in layman terms, if you take phone
`
`14
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`2 calls, you're a server. If you initiate them,
`
`3 you're a client. Soto eliminate confusion, the
`
`4 first process in this claim means server, and
`
`5
`
`second process means another server which is
`
`6 subject —— which registers itself is the first
`
`7 server.
`
`The above testimony is relevant to (1) Exhibit 1023, the Antonov
`
`Declaration; and (2) Paper No. 33, the Petitioner’s Reply. This testimony
`
`contradicts Patent Owner’s observation set forth above and shows that Mr.
`
`Antonov’s testimony further explained his declaration and the relevant technology
`
`in response to counsel’s questions.
`
`B.
`
`Response to Observation 9
`
`In response to Patent Owner’s Observation 9 and specifically that “Mr.
`
`Antonov’s Testimony Demonstrates a Connection Between Petitioner’s Expert and
`
`Stalker Software,” Petitioner respectfully notes that in Exhibit 2045, on Page 173,
`
`Line 12 through Page 174, Line 23, Mr. Antonov testified that:
`
`Ex. 2045, Page 173, Line 12, through, Page 174, Line 23
`
`12
`
`13
`
`Q. How do you know Mr. Butenko?
`
`MR. MORLOCK: Objection, outside the scope
`
`14 of direct.
`
`15
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`15
`
`THE WITNESS: We studied in the same
`
`16 university on different departments. And I was at
`
`17 Department of Computer Science. He was at
`
`18 Department of Physics. And we met because we were
`
`19 both active in systems programming community. And
`
`20 we kept in contact since then.
`
`21
`
`22
`
`23
`
`MR. HOFFMAN:
`
`Q. So you're friends with him today?
`
`MR. MORLOCK: Objection, outside the scope
`
`24 of direct.
`
`25
`
`THE WITNESS: You could say that we're
`
`0174
`
`1
`
`friends. I would say acquaintances.
`
`2
`
`3
`
`4
`
`MR. HOFFMAN:
`
`Q. So are you familiar with Stalker Software?
`
`MR. MORLOCK: Objection, outside the scope
`
`5 of direct.
`
`6
`
`THE WITNESS: I know that he founded that
`
`7 company, and I know, roughly, what as a company is
`
`8 doing. I didn't use Stalker Software products. I
`
`16
`
`
`
`Case No. IPR2013—00246
`
`U.S. Patent No. 6,108,704
`
`9 do not know details of what's in them. And we
`
`10 never discussed our —— talked about current
`
`11 operations of the company, and —— and we never did
`
`12 any business together.
`
`13
`
`14
`
`MR. HOFFMAN:
`
`Q. Have you had any discussions with
`
`15 Mr. Butenko about this matter?
`
`16
`
`MR. MORLOCK: Objection, outside the scope
`
`17 of direct.
`
`18
`
`THE WITNESS: No, we didn't. And I --
`
`19 I've heard that he's involved in some kind of
`
`20 patent litigation. I didn't know what this is
`
`21 about and why it was there. I only learned about
`
`22 involvement of Stalker Software when I was reading
`
`23 the documents related to this case.
`
`The above testimony is relevant to ( 1) Paper 30, Pages 8-16; and (2) Paper
`
`33, Pages 1-4. This testimony contradicts Patent Owner’s observation regarding a
`
`“relationship” between Petitioner and Stalker Software and it is relevant to
`
`demonstrate that Mr. Antonov’s testimony showed nothing more than his mere
`
`knowledge of Stalker Software and a friendship with stalker’s CEO.
