`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`INTRODUCTION
`
`
`I.
`
`Petitioner’s Motion to Exclude Evidence ignores the fact that Patent
`
`Owner’s Exhibits 2036-2039 simply include additional results of the lens design
`
`that Petitioner and its declarant, Mr. Juergens, omitted from the reply brief and
`
`accompanying exhibits. Significantly, Petitioner does not dispute that Mr.
`
`Juergens’ Supplemental Declaration merely shows how his lens designs affect light
`
`originating from only two field points out of the entire field width. Nor does
`
`Petitioner appear to dispute that Mr. Juergens’ lens designs fail to properly form a
`
`usable image – a result that Patent Owner’s Exhibits 2036-2039 confirm by
`
`showing how the lens designs affect all light originating from the entire field
`
`width.
`
`Petitioner provides no credible basis for excluding the evidence, testimony,
`
`or observations that it finds objectionable. Mr. Juergens and Patent Owner’s
`
`expert, Dr. Sasian, have each authenticated Exhibits 2036-2039. Furthermore,
`
`there is no hearsay issue here because the results in Exhibits 2036-2039 are simply
`
`the output of Mr. Juergen’s lens design. Similar to the way an algebraic function
`
`operates on inputs to generate outputs, the effect of the lens design on different
`
`field points is immutable. The lens design will always have the same effect on the
`
`same light originating from the same field point.
`
`
`
`1
`
`
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`Petitioner has been afforded ample opportunity to verify the effect of Mr.
`
`Juergens’ lens designs on light originating from all of the field points in the field
`
`width. Thus, Petitioner has not been prejudiced by its inability to take further
`
`depositions – Petitioner could have simply checked the effect of Mr. Juergens’ lens
`
`designs on the entire field width instead of studiously omitting them from its reply
`
`brief and accompanying exhibits.
`
`Accordingly, Petitioner’s Motion to Exclude should be denied.
`
`II.
`
` COUNTERSTATEMENT OF MATERIAL FACTS
`
`On May 28, 2014, Petitioner Zeiss filed its Reply to Patent Owner’s
`
`Response (Doc. No. 22) along with several corresponding exhibits, including
`
`Exhibits 1036 and 1038-1049 that purportedly show for the first time how
`
`Petitioner’s expert, Mr. Juergens, utilized optical design software to modify a prior
`
`art lens system to generate a lens system that falls within the scope of the claims
`
`under review. Subsequently, Patent Owner cross-examined Mr. Juergens to
`
`demonstrate that his computer-assisted lens designs described in Exhibits 1036 and
`
`1038-1049 are inoperable, specifically because those lens designs fail to properly
`
`form an image that is focused. (Ex. 2040, 110:12 – 111:21, 115:2 – 117:14,
`
`123:22 – 125:19 ). Moreover, Mr. Juergens’ cross-examination testimony
`
`
`
`2
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`demonstrated that some of the lens designs are inoperable because they suffer from
`
`beam separation problems.1 (Ex. 2040, 117:15 – 120:1).
`
`As evidenced by Exhibits 1036 and 1038-1049, Mr. Juergens curiously only
`
`plotted two field points for his computer-assisted lens designs. The output
`
`provided for those two field points suggests that the lens designs are usable in a
`
`projection optical system to form an effective image. (Paper 22 at pages 12-13.)
`
`Patent Owner’s Exhibits 2036-2039, on the other hand, plot the entire field width
`
`of Mr. Juergens’ lens system, not just the two points that he selected. The output
`
`for the complete field points demonstrate without question that Mr. Juergens’
`
`computer-assisted lens designs fail to properly form an image that is focused (Ex.
`
`2040, 110:12 – 111:21, 115:2 – 117:14, 123:22 – 125:19 ) and, in some cases, are
`
`also inoperable because they fail to properly separate the beam paths. (Ex. 2040,
`
`118:20-120:13.)
`
`Accordingly, Exhibits 1036 and 1038-1049 are irrelevant to Petitioner’s
`
`positions on obviousness and enablement, but are nonetheless conditionally
`
`relevant to Patent Owner’s position that the challenged claims are not obvious and
`
`
`1 Patent Owner has submitted observations on Mr. Juergens’ deposition testimony
`
`that reveal in further detail the severity of the problems with his freshly-minted
`
`computer-assisted lens designs submitted for the first time with Petitioner’s Reply.

`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`that the prior art is not enabling in view of Mr. Juergens’ cross-examination
`
`testimony and related Exhibits 2036-2039.
`
`III. RELEVANT LAW
`
`The Federal Rules of Evidence (“FRE”) apply to the current proceedings.
`
`37 C.F.R. § 42.62.
`
`IV. ARGUMENT
`
`A. Mr. Juergens and Dr. Sasian Each Authenticated Exhibits 2036-
`2039
`
`Mr. Juergens has over twenty-five years of experience working with optical
`
`
`
`design software, first as an Assistant Director of Marketing for Optical Research
`
`Associates from 1988-1999 and then as a consultant for Cimarron Optical
`
`Consulting, starting in 1999. As a consultant, he has performed comparisons of
`
`optical design software and conducted lens design and analysis using optical
`
`design software. (Ex. 1028, 1-2.) Mr. Juergen’s curriculum vitae touts the
`
`following:
`
`Mr. Juergens is an expert user of the CODE V optical design software,
`which is used by many optical designers world-wide, such as those at
`Zeiss in Germany and Nikon in Japan (both places of which he has
`visited and given seminars and technical support). He worked 11
`years at Optical Research Associates, the suppliers of CODE V, and
`went around the world giving seminars, lectures, and technical
`support on how to use CODE V effectively for design and analysis of
`
`
`
`4
`
`
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`all kinds of optical systems, including lithographic systems. (Ex.
`1028, 1.)
`
`Mr. Juergens also testified as to his familiarity with how optical design software is
`
`commonly used to design lens systems and determine RMS wavefront error for a
`
`lens design at specified field points. Accordingly, Mr. Juergens is amply qualified
`
`to recognize the output of optical design software.
`
`
`
`With respect to the specific output shown in Exhibits 2036-2039 for the
`
`Terasawa lens design and the lens designs that Mr. Juergens generated for his
`
`supplemental declaration, Mr. Juergens has sufficient knowledge of those designs
`
`to authenticate the output resulting from those same designs in Exhibits 2036-
`
`2039. See FRE 901(a). In particular, Mr. Juergens executed his supplemental
`
`declaration on May 27, 2014, in which he describes in detail his analysis of the
`
`very lens designs described by Exhibits 2036-2039. (See, e.g., Ex. 1036 ¶¶ 15, 22,
`
`30, 40, 49.) A little over a month after he submitted his supplemental declaration,
`
`Mr. Juergens testified on cross-examination that Exhibits 2036-2039 are what they
`
`claim to be, i.e., additional plots for the field points in the field width of the very
`
`designs that Mr. Juergens analyzed in his supplemental declaration. (Ex. 2040,
`
`74:12 -75:13, 108:14 - 109:12, 113:21 – 116:1, 116:17-117:6, 123:1-21.)
`
`Representative samples of that testimony are as follows:
`
`Q. Do you understand the plot shown in Figure 1?
`
`
`
`5
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`A. Yes.
`Q. On Page 2 would you likewise agree that it is a plot of distortion
`based on the Table 2 in Terasawa?
`MR. WEFERS: Objection, foundation. Objection, scope.
`A. Yes. (Ex. 2040, 75:2-10, emphasis added.)
`
`Q. So this exhibit is a plot of the RMS wavefront error corresponding
`to your example number two in -- or as set forth in your Exhibit
`1042. Do you recognize the plot shown on Page 1?
`A. I recognize what it is.
`Q. Could you please explain what you believe it to be?
`A. It's a plot of RMS wavefront error versus field height.
`Q. So -- scratch that. Does it surprise you that your design
`corresponding to Experiment Number II corresponding to the
`CODE V lens layout from Exhibit 1042 produces a plot as shown
`in Figure 1?
`MR. WEFERS: Objection, foundation.
`A. No. (Ex. 2040, 109:2-19, emphasis added.)
`
`Q. So, again, what in your opinion is shown on Page 1 of this exhibit?
`A. It shows RMS wavefront error versus field.
`Q. So would you agree that this is the RMS wavefront error
`corresponding to the CODE V lens layout for the exhibit marked
`1049 of your Supplemental Declaration?
`A. I can accept that. (Ex. 2040, 123:14-21.)
`
`6
`
`
`
`
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`Accordingly, Mr. Juergens was able to authenticate Exhibits 2036-2039 as plots
`
`resulting from his own lens designs.
`
`
`
`Independently, Patent Owner’s expert, Dr. Sasian, executed a second
`
`declaration (Ex. 1054) that authenticates Exhibits 2036-2039 as plots resulting
`
`from the lens designs that Mr. Juergens generated for his supplemental declaration.
`
`Petitioner appears to concede that Dr. Sasian’s second declaration is sufficient to
`
`authenticate Exhibits 2036-2039, but complains that the declaration is not timely,
`
`citing to 37 C.F.R. 42.64(a).
`
`
`
`A waiver of Rule 42.64 is warranted in this situation because Petitioner is
`
`not in any way prejudiced by receiving Dr. Sasian’s second declaration after the
`
`deposition, and because Patent Owner will suffer an easily-avoidable injustice if
`
`the record includes plots for all field points in the field width of Mr. Juergens’
`
`designs rather than the two field points that suggest that the prior art is enabling.
`
`Had Patent Owner presented Dr. Sasian’s second declaration to counsel for
`
`Petitioner during Mr. Juergens’ cross-examination, nothing about the deposition
`
`would have changed. Dr. Sasian’s second declaration merely shows that he was
`
`the person responsible for “plugging in” Mr. Juergens’ lens designs into computer
`
`software that could plot points in the field width of Mr. Juergens’ designs. Even if
`
`Petitioner were afforded the opportunity to cross-examine Dr. Sasian on his second
`
`declaration, there is nothing that Petitioner could obtain from such testimony other
`
`
`
`7
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`than that Dr. Sasian performed data entry to load Mr. Juergens’ designs into
`
`software that plotted additional points in the field width of Mr. Juergens’ designs.
`
`
`
`Exhibits 2036-2039 include the parameters of Mr. Juergens’ lens designs,
`
`which Petitioner could have checked for accuracy during the deposition or
`
`subsequently. Further, Petitioner could have checked the accuracy of Exhibits
`
`2036-2039 by simply plotting additional points in the field width of Mr. Juergens’
`
`designs.
`
`
`
`Due to the unique situation that Petitioner has created by submitting with its
`
`Reply new lens designs and plots for two field points that allegedly show that the
`
`prior art enabled the scope of the claims under review, Patent Owner was denied an
`
`opportunity to have its own expert replicate and opine on the relevance of Mr.
`
`Juergens’ optical modeling process. Waiver of Rule 42.64 is justified here because
`
`a gross injustice will occur if Patent Owner’s plots for all field points in the field
`
`width are not allowed into the record to show that Mr. Juergens’ lens designs are
`
`inoperable to form an effective image, as claimed in the 575 patent.
`
`B.
`
`Exhibits 2036-2039 Are Not Hearsay, and Even if They Were,
`They Fall within the Hearsay Exception
`
`As an initial matter Exhibits 2036-2039 are not hearsay. They are not
`
`statements by Dr. Sasian. Nor do they fall under the definition of a “statement”
`
`under FRE 801(a) because they are not written assertions. They are simply the
`
`plots that Mr. Juergens’ lens designs generate for the entire field width instead of
`
`
`
`8
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`the two points that Mr. Juergens plotted. Similar to the way an algebraic function
`
`operates on an input “x” to generate a plot of “y,” the effect of a lens design on
`
`different field points is immutable.
`
`If there were a practical way to express Mr. Juergens’ lens designs
`
`mathematically, Patent Owner could have asked Mr. Juergens to plot additional
`
`field points at his deposition. Instead, computer software is required to plot the
`
`field points for a complex lens system. It does not matter who enters the data or
`
`runs the optical modeling software – the software will always output the same plot
`
`for each field point for the same lens design. Exhibits 2036-2039 reflect the
`
`complete results of Mr. Juergen’s lens designs, which Petitioner, not Patent Owner,
`
`has introduced into the record. Accordingly, Exhibits 2036-2039 are not hearsay.
`
`In its motion to exclude (at 9), Petitioner relies on the Board’s decision in
`
`Shu-hui Chen v. Herve Bouchard, Patent Interference No. 103,672, 2002 Pat. App.
`
`LEXIS 201 (BPAI Aug. 2, 2002). While Patent Owner agrees that the Board in
`
`Shu-hui Chen determined that certain scientific data was inadmissible hearsay, the
`
`facts from that case are easily distinguished from the instant matter. First, unlike
`
`here, there was a serious authenticity dispute regarding who actually created the
`
`laboratory notebooks and scientific data relating thereto in Shu-hui Chen. As noted
`
`above, there is no dispute that the subject data here is generated from Mr.
`
`Juergens’ lens designs. Second, and most importantly, the Shu-hui Chen case did
`
`
`
`9
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`not involve a situation caused by a party like Petitioner here who attempted to
`
`improperly smuggle evidence into the proceeding by way of a reply brief.
`
`Additionally, Exhibits 2036-2039 fall within the residual exception to
`
`hearsay, FRE 807. First, Exhibits 2036-2039 do not fall within another hearsay
`
`exception but they have the equivalent circumstantial guarantee of trustworthiness
`
`as other hearsay exceptions. Specifically the exhibits are plots that Mr. Juergens’
`
`lens design mathematically generated. The accuracy of the plots can be easily
`
`confirmed by Petitioner.
`
`Second, Exhibits 2036-2039 are offered as evidence of a material fact, i.e.,
`
`that Mr. Juergens’ lens designs are inoperable to form an effective image.
`
`Third, Exhibits 2036-2039 are more probative on the point for which they
`
`are offered than any other evidence that Patent Owner can obtain through
`
`reasonable efforts. Specifically, Patent Owner filed its response long before Mr.
`
`Juergens' lens designs were submitted, and the schedule for this proceeding does
`
`not permit Patent Owner a chance to submit a declaration of an expert to provide
`
`opinions and analysis pertaining to Mr. Juergens’ lens designs.
`
`Fourth, admitting Exhibits 2036-2039 best serves the purposes of the FRE
`
`and the interests of justice. In Petitioner’s Exhibits 1036 and 1038-1049, Mr.
`
`Juergens only plotted two field points out of the entire field width for his
`
`computer-assisted lens designs. Exhibits 2036-2039 contain plots for all the points
`
`
`
`10
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`
`in the field width, and thus, provide the “rest of the story.” In particular, Exhibits
`
`2036-2039 are necessary to correct the false impression that Petitioner’s Exhibits
`
`1036 and 1038-1049 give with respect to the usefulness of Mr. Juergens’ lens
`
`designs and whether the prior art enabled the claimed invention. Without the
`
`addition of Exhibits 2036-2039 and the related cross-examination testimony of Mr.
`
`Juergens, there is no evidence to rebut Petitioner’s and Mr. Juergens’ erroneous
`
`conclusions that computer modeling software successfully modified the prior art to
`
`generate an immersed lens design. Petitioner’s Reply (Paper No. 22) at pages 12-
`
`13 is indicative of this problem:
`
`Mr. Juergens showed that a POSITA could have used CODE V to
`redesign the optical prescription for FIG. 5 in Terasawa by adding an
`immersion fluid between the last lens surface and the wafer to
`increase DOF, adjusting the thicknesses and curvatures of certain
`lenses, and re-optimizing the aspheric coefficients of the system to
`obtain an imaging performance as good as, or better than, the
`original dry design. (ZEISS 1036, ¶¶ 15-31, 43-47, emphasis added.)
`
`Patent Owner’s Exhibits 2036-2039 clearly disprove sweeping statements such as
`
`those made above. It is plainly within the interests of justice to admit into the
`
`record the other plots generated by the same lens designs.
`
`C.
`
`Irrespective of Hearsay, Exhibits 2036-2039 May Still Be Relied
`Upon for the Limited Purpose of Demonstrating that Petitioner’s
`Exhibits 1036 and 1038-1049 Have No Probative Value
`
`
`
`11
`
`
`
`
`
`Case IPR2013-00362
`Patent Owner’s Opposition to Petitioner’s Motion to Exclude Evidence
`
`Lastly, even if the Board is inclined to exclude Exhibits 2036-2039, they
`
`should at least be admitted for the limited purpose of demonstrating that
`
`Petitioner’s Exhibits 1036 and 1038-1049 are incomplete and thus should be given
`
`little weight (if any). Specifically, Petitioner’s Exhibits 1036 and 1038-1049 plot
`
`only two field points out of the entire field width. Patent Owner’s Exhibits 2036-
`
`2039 demonstrate that the plots of only two field points is not probative of whether
`
`the prior art enables the claims under review.
`
`If admitted for this limited purpose, Exhibits 2036-2039 could not constitute
`
`hearsay because they are not offered for the truth of the matter asserted.
`
`Innovention Toys, LLC v. MGA Entm't, Inc., 2012 U.S. Dist. LEXIS 158194, at *
`
`6-7 (E.D. La. Nov. 4, 2012) (holding that certain letters were not hearsay because
`
`they were not offered to prove the truth of the matters asserted in those letters, but
`
`instead to show the accused infringer’s state of mind). In this case, Exhibits 2036-
`
`2039 would not be offered to prove that the prior art is not enabling, but rather to
`
`show that Petitioner’s Exhibits 1036 and 1038-1049 paint an incomplete and
`
`misleading picture.
