`
`
`
`PATENT OWNER’S OPPOSITION TO
`PETITIONER’S MOTION TO EXCLUDE
`
`
`
`
`
`

`
`
`
`
`
`Patent Owner respectfully submits this opposition to Petitioner’s motion to
`
`exclude. As explained below, Petitioner’s objections on hearsay and relevance
`
`grounds are entirely unfounded, and should be rejected. Furthermore, Petitioner’s
`
`argument that the obviousness analysis in this case should be conducted without
`
`recognition of the properties of the claimed CuCHA zeolite catalyst is entirely
`
`inconsistent with Federal Circuit precedent. Petitioner’s motion to exclude should
`
`be denied in its entirety.
`
`I. MOTION TO EXCLUDE PARAGRAPHS OF TSAPATSIS
`DECLARATION
`A. Tsapatsis Declaration, ¶ 28
`Petitioner moves to exclude ¶ 28 of the Tsapatsis Declaration (Ex. 2018),
`
`
`
`which cites ¶ 4 of the Declaration of Dr. Ahmad Moini (Ex. 2003) from the inter
`
`partes reexamination history of the 662 Patent. Petitioner incorrectly contends that
`
`¶ 4 of the Moini declaration is irrelevant and that the un-cross examined testimony
`
`of Dr. Moini is unreliable.
`
`
`
`First, Dr. Tsapatsis cites the Moini declaration to rebut the unsupported
`
`assertions by Petitioner’s expert, Dr. Lercher, that the technology at issue in this
`
`case is predictable, and that it was simply a matter of routine optimization to arrive
`
`at the claimed invention. The undisputed fact that the inventors of the 662 Patent
`
`performed broad experimentation before arriving at the claimed invention is
`
`clearly relevant to whether the technology at issue is complex and unpredictable.
`
`
`
`

`
`
`
`Furthermore, Dr. Tsapatsis’ opinion is not based solely on ¶ 4 of the Moini
`
`declaration. Instead, Dr. Tsapatsis cites substantial evidence to support his opinion
`
`that the relevant technology is complex and unpredictable. See Ex. 2018 at ¶¶ 28,
`
`56-75, 151-167, 172.
`
`
`
`Petitioner is also wrong that there is no evidence in the record indicating that
`
`the screening of 900 zeolite materials and 12 different structure types was directed
`
`to problems solved by the 662 Patent. Dr. Moini’s declaration explicitly states that
`
`the screening was done “to provide a material for selective catalytic reduction that
`
`would have two main properties: (1) excellent NOx conversion over a wide
`
`temperature range…and (2) hydrothermal stability…” Ex. 2003 at ¶ 3.
`
`
`
`Second, Petitioner’s argument that the “uncross-examined declaration” is not
`
`the type of information on which an expert would ordinarily rely is wholly without
`
`merit. There is no rule that an expert can only rely on testimony that has been
`
`subject to cross-examination. See FRE 703. And even if there were such a
`
`requirement, the only reason Dr. Moini was not cross-examined was because
`
`Petitioner voluntarily decided not to proceed with the deposition that had been
`
`scheduled for April 27, 2016.
`
`Tsapatsis Declaration, ¶ 174
`
`B.
`Petitioner moves to exclude ¶ 174 of the Tsapatsis Declaration, which cites
`
`
`
`to the Second Declaration of Dr. Moini (Ex. 2011). This Second Moini declaration
`
`
`
`3
`
`

`
`
`
`is also part of the 662 reexamination history and includes testimony regarding
`
`testing of zeolite catalysts. Petitioner argues that the testing should be disregarded
`
`because the natural chabazite samples tested by Dr. Moini were not from the same
`
`source as the natural chabazite samples discussed in the Dedecek prior art
`
`reference. Petitioner, however, offers no evidentiary rule for excluding either ¶
`
`174 of the Tsapatsis declaration or the Second Moini declaration. Dr. Moini
`
`explicitly noted in his declaration that the natural chabazite discussed in Dedecek
`
`was from North Korea, and therefore, not available to him. Ex. 2011 at ¶ 5. He
`
`instead utilized a comparable natural chabazite from Bowie, Arizona. Id.
`
`
`
`Petitioner’s expert, Dr. Lercher, and Patent Owner’s expert, Dr. Tsapatsis,
`
`each reviewed the Second Moini declaration and neither offered any opinion that
`
`the testing was insufficient, improper, or otherwise unreliable. Ex. 2018 at ¶ 174;
`
`Ex. 2027 at 84:22-25. In fact, Dr. Lercher’s 120-page declaration is entirely silent
`
`about the testing performed by Dr. Moini. Ex. 1108. Petitioner offers no reasoned
`
`explanation for why the use of the sample from Bowie, Arizona renders the testing
`
`unreliable.
`
`
`
`Petitioner also argues that ¶ 25 of the Second Moini declaration includes
`
`hearsay, and on this basis, requests that ¶ 174 of the Tsapatsis declaration be
`
`excluded (even though it does not cite ¶ 25 of the Second Moini declaration). In ¶
`
`25, Dr. Moini explains where certain samples came from, how the samples were
`
`
`
`4
`
`

`
`
`
`prepared, the parameters of the samples, and the results of the testing. Ex. 2011 at
`
`¶ 25. This is not hearsay, and Petitioner certainly has no argument that Dr. Moini
`
`was not competent to testify about these facts based on his personal knowledge.
`
`FRE 602. Moreover, even assuming ¶ 25 of the Second Moini declaration includes
`
`hearsay, that is not a sufficient basis on which to exclude ¶ 174 of the Tsapatsis
`
`Declaration. FRE 703.
`
`C. Tsapatsis Declaration, ¶ 48
`Petitioner moves to exclude ¶ 48 of the Tsapatsis declaration because it cites
`
`
`
`to the Second Ravindran declaration (Ex. 2004), which is part of the 662 inter
`
`partes reexamination history. The Second Ravindran declaration includes Mr.
`
`Ravindran’s testimony that BASF sent a sample to Ford, Ford tested the sample,
`
`and published the results in a paper (Ex. 2002). As is clear from the declaration,
`
`these facts were known to Mr. Ravindran, and Petitioner, having elected not to
`
`cross-examine Mr. Ravindran, has no argument that Mr. Ravindran did not have
`
`personal knowledge of these facts.
`
`
`
`Petitioner also contests the Second Ravindran declaration on the grounds
`
`that an email from Ford Motor Company referenced in ¶ 8 of declaration was not
`
`attached to the declaration. The omission of this email from the Second Ravindran
`
`declaration does not warrant exclusion of ¶ 48 of the Tsaptasis declaration. First,
`
`Petitioner has not moved to exclude ¶ 8 of the Ravindran declaration from the
`
`
`
`5
`
`

`
`
`
`record. Second, even if ¶ 8 of the Ravindran declaration were not admissible
`
`evidence, it would still be permissible for Dr. Tsapatsis to rely on this paragraph of
`
`the Ravindran declaration for purposes of determining the nature of the material
`
`that was tested in the Ford paper. The Ravindran testimony is clearly probative of
`
`whether the material tested by Ford, and described as “remarkable” in the Ford
`
`Paper, falls within the scope of the 662 claims, and Petitioner has not identified
`
`any prejudicial effect to admitting the testimony. FRE 703 (“…if the facts or data
`
`would otherwise be inadmissible, the proponent of the opinion may disclose them
`
`to the jury only if their probative value in helping the jury evaluate the opinion
`
`substantially outweighs their prejudicial effect.”).
`
`D. Tsapatsis Declaration, ¶ 79
`Petitioner moves to exclude ¶ 79 of the Tsapatsis declaration because it cites
`
`
`
`to the Zones declaration (Ex. 2009), which is part of the 662 inter partes
`
`reexamination history. Dr. Tsapatsis cites to ¶ 8 of the Zones declaration as
`
`supporting his opinion that the phrase “catalyzing the reduction of the oxides of
`
`nitrogen” encompasses a number of different reactions. Even assuming the Zones
`
`declaration is inadmissible does not mean that ¶ 8 of the Tsapatsis declaration
`
`should be excluded. FRE 703. Furthermore, it is undisputed that the phrase
`
`“catalyzing the reduction of the oxides of nitrogen” encompasses a number of
`
`different reactions. Petitioner’s expert, Dr. Lercher, agreed at his deposition that
`
`
`
`6
`
`

`
`
`
`the phrase encompasses a number of different reactions exactly as stated in ¶ 8 of
`
`the Zones Declaration. Ex. 2027 at 37:19-38:22.
`
`Tsapatsis Declaration, ¶ 170
`
`E.
`Petitioner moves to exclude ¶ 170 of the Tsapatsis declaration because it
`
`
`
`cites to the Roth declaration (Ex. 2001), which is part of the 662 inter partes
`
`reexamination history. Dr. Tsapatsis’ declaration notes that Dr. Roth submitted a
`
`declaration in which he discusses skepticism expressed by the Department of
`
`Energy. Experts are permitted to base their opinions on the testimony of others,
`
`and there is no requirement that the testimony relied on be admissible. FRE 703.
`
`Furthermore, Petitioner has not moved to exclude the Roth declaration, which is
`
`separately cited at pages 40-41 of Patent Owner’s Response (Paper No. 25).
`
`II. MOTION TO EXCLUDE OPINIONS REGARDING PROPERTIES
`OF THE CLAIMED MATERIAL
`
`
`
`Petitioner moves to exclude paragraphs ¶¶ 54-55, 62-71, and 168-177 of the
`
`Tsapatsis declaration on the basis that they focus on “irrelevant and unclaimed
`
`catalyst features.” Petitioner is essentially requesting that the Board consider the
`
`issue of obviousness of the claimed CuCHA zeolite catalyst without reference to
`
`the properties exhibited by the claimed CuCHA catalyst. As explained below, as
`
`well as in Patent Owner’s Response to the Petition, Paper No. 25, at pp. 13-15,
`
`Petitioner’s argument is contrary to the law.
`
`
`
`
`
`First, Petitioner states that the “none of the ‘662 patent claims at issue in this
`
`7
`
`

`
`
`
`IPR require either ‘low temperature SCR activity’ or ‘improved hydrothermal
`
`durability.’” This argument misses the mark. The claims are directed to an
`
`aluminosilicate CuCHA catalyst having a SAR within various ranges (15-150, 15-
`
`100, 25-40, or 30) and a Cu/Al ratio within various ranges (0.25-1, 0.30-0.50,
`
`0.40), and used for the selective catalytic reduction of NOx in the presence of NH3
`
`(“NH3-SCR of NOx”). As explained by Dr. Tsapatsis, a zeolite catalyst having
`
`these parameters has been shown to exhibit certain NOx conversion percentages.
`
`Ex. 2018, ¶¶ 48-49 (discussing NOx conversion percentages disclosed in third party
`
`research papers), ¶¶ 54-55 (discussing NOx conversion percentages disclosed in the
`
`662 Patent), ¶¶ 147-150 (discussing NOx conversion percentages shown by Dr.
`
`Schutze). These properties must be considered in the evaluation of obviousness of
`
`the claimed CuCHA zeolite catalyst. Otsuka Pharm. Co. v. Sandoz, Inc., 678 F.3d
`
`1280, 1292 (Fed. Cir. 2012) (internal citations omitted) (“In determining whether a
`
`chemist would have selected a prior art compound as a lead, the analysis is guided
`
`by evidence of the compound's pertinent properties. Such properties may include
`
`positive attributes such as activity and potency, adverse effects such as toxicity,
`
`and other relevant characteristics in evidence. Absent a reason or motivation based
`
`on such prior art evidence, mere structural similarity between a prior art compound
`
`and the claimed compound does not inform the lead compound selection.”);
`
`Sanofi-Synthelabo v. Apotex, Inc., 550 F.3d 1075, 1086 (Fed. Cir. 2008) (“For
`
`
`
`8
`
`

`
`
`
`chemical compounds, the structure of the compound and its properties are
`
`inseparable considerations in the obviousness determination.”); In re Papesch, 315
`
`F.2d 381, 391 (CCPA 1963) (“From the standpoint of patent law, a compound and
`
`all of its properties are inseparable; they are one and the same thing.”); see also
`
`United States v. Adams, 383 U.S. 39, 48-49 (1966).
`
`
`
`Second, Petitioner also points out in its motion that not all CuCHA catalysts
`
`that fall within the claimed ranges perform equally. Specifically, Petitioner makes
`
`much of the fact that Example 1 in the 662 Patent, while falling within the scope of
`
`claim 1, does not perform as well as Examples 2 and 3 in the 662 Patent.
`
`However, the issue at hand is not how the claimed invention compares to itself, but
`
`how the claimed invention compares to the prior art. As explained by Dr.
`
`Tsapatsis, and not contested by Petitioner’s expert, Example 1 of the 662 Patent
`
`exhibits significantly better aged NOx conversion performance in comparison to
`
`the prior art Cu-Beta sample. Ex. 2018 at ¶¶ 54-55. Moreover, there is clear
`
`evidence that the claimed CuCHA catalyst produces unexpected results in
`
`comparison to the prior art. Patent Owner’s Response, Paper No. 25, at pp. 42-45.
`
`
`
`Finally, Petitioner cites Tyco Healthcare Grp. v. Mut. Pharm. Co., 642 F.3d
`
`1370 (Fed. Cir. 2011) for the proposition that the NOx conversion performance of
`
`the claimed CuCHA catalyst is irrelevant to the question of obviousness. The
`
`claim at issue in Tyco Healthcare was directed to a capsule including temazepam,
`
`
`
`9
`
`

`
`
`
`but did not specify an intended use for the capsule. The only distinction between
`
`the claimed capsule and the main prior art Restoril® capsules was a lower amount
`
`of temazepam, which was disclosed in other prior art. In the present case, the
`
`claims of the 662 Patent specify an intended use—NH3-SCR of NOx. Moreover, in
`
`the present case and unlike the Tyco Healthcare case (i) there is no evidence in the
`
`prior art of general efficacy of a CHA zeolite for the NH3-SCR of NOx; (ii) there is
`
`prior art that teaches away from the use of a CHA zeolite for such a reaction; and
`
`(iii) there is evidence of unexpected results. Tyco Healthcare, 642 F.3d at 1373
`
`(“[The] presumption [of obviousness] is rebuttable either by a showing that the
`
`prior art taught away from the invention or by a showing of new and unexpected
`
`results relative to the prior art.”). First, as explained by Dr. Tsapatsis, none of the
`
`prior art references in the grounds presented by Petitioner discuss the NOx
`
`conversion performance of a CHA zeolite used for the NH3-SCR of NOx. Ex. 2018
`
`at ¶¶ 72-74, 80, 85, 90, 97. Second, as also explained by Dr. Tsapatsis, the only
`
`prior art reference that discusses the performance of a CHA zeolite for the NH3-
`
`SCR of NOx explicitly teaches away from using a CHA zeolite. Ex. 2018 at ¶¶ 75,
`
`173. Finally, there is firm evidence of unexpected results. The well-known
`
`problem of hydrothermal stability of zeolite catalysts was documented in the prior
`
`art beginning as early as 1995 and as late as 2008. Ex. 2018 at ¶ 66-70. It is
`
`undisputed that the claimed CuCHA catalyst solved this problem, and that the NOx
`
`
`
`10
`
`

`
`
`
`conversion performance exhibited by the CuCHA catalyst would not have been
`
`expected in view of the closest prior art. Ex. 2018 at ¶¶ 48, 49, 63, 172-174.
`
`III. MOTION TO EXCLUDE ANALYSIS OF DR. SCHUTZE’S DATA
`
`Petitioner moves to exclude ¶¶ 147-150 of the Tsapatsis declaration. These
`
`paragraphs directly rebut the erroneous conclusions that were drawn by
`
`Petitioner’s expert, Dr. Lercher, using the data in the Schutze declaration (Ex.
`
`1115). Specifically, Dr. Lercher concluded, based solely on the Schutze data, that
`
`the claimed SAR and Cu/Al ratios lacked criticality. Dr. Tsapatsis reviewed the
`
`same data, and presented a clear analysis showing the exact opposite. Petitioner,
`
`now realizing the clear error in their own expert’s analysis, asks the Board to
`
`exclude the reasoned analysis of Dr. Tsapatsis as unreliable because it “is based on
`
`isolated testing points.” Petitioner’s motion to exclude has no merit.
`
`
`
`First, with respect to the Cu/Al ratio, Dr. Tsapatsis graphed the Schutze data
`
`for both the SAR 30 fresh and aged samples, to show how the lower Cu/Al
`
`boundary of 0.25 has criticality. Ex. 2018 at ¶¶ 147-150. The criticality of the
`
`boundary is clear from the figures themselves and the supporting explanation by
`
`Dr. Tsapatsis. Id. In addition, the graphs also refute the argument by Dr. Lercher
`
`that adjusting Cu/Al ratio produces a linear, predictable increase in NOx conversion
`
`performance.
`
`
`
`11
`
`

`
`
`
`
`
`
`The same is true for the SAR lower boundary of 15. The graph and
`
`
`
`supporting explanation by Dr. Tsapatsis plainly show that the SAR 15 boundary
`
`has criticality. Ex. 2018 at ¶¶ 147-
`
`150. And likewise, the analysis by
`
`Dr. Tsapatsis also shows that
`
`increasing SAR does not produce a
`
`linear, predictable improvement in
`
`NOx conversion performance after
`
`hydrothermal aging as Dr. Lercher
`
`wrongly concluded.
`
`IV. MOTION TO EXCLUDE PARAGRAPH ¶ 11 OF MOINI
`DECLARATION (EX. 2019)
`
`
`
`Petitioner moves to exclude ¶ 11 of the Moini Declaration (Ex. 2019). In
`
`this paragraph, Dr. Moini discusses the commercial CuCHA catalyst sold by Patent
`
`Owner. Dr. Moini explains that the CuCHA catalyst is sold on a substrate (either a
`
`
`
`12
`
`

`
`
`
`flow-through substrate or a wall flow filter), that the catalyst is specifically made
`
`for use in the NH3-SCR of NOx in the exhaust treatment system of a diesel engine,
`
`and that customers purchase the CuCHA catalyst because of properties of the
`
`CuCHA material coated on the substrate. Petitioner argues that Dr. Moini lacks
`
`personal knowledge, the statement regarding customers is hearsay, and the
`
`testimony is irrelevant. Petitioner is incorrect on all counts.
`
`
`
`First, Dr. Moini’s declaration specifically states that he is a Senior Expert
`
`and Research Fellow at BASF, a named inventor of the 662 Patent, and that he is
`
`familiar with the product specification for the CuCHA zeolite catalyst that is
`
`commercially sold by BASF. He further notes in his declaration that the final
`
`CuCHA catalyst product that is sold to customers is made according to the product
`
`specification. Thus, there is clear foundation that Dr. Moini has personal
`
`knowledge regarding the specification and manufacture of the commercial CuCHA
`
`zeolite catalyst. There is also foundation establishing that Dr. Moini is qualified to
`
`offer testimony as to why BASF customers purchase the CuCHA zeolite catalyst.
`
`In addition to being a Senior Expert and Research Fellow at BASF and a named
`
`inventor of the 662 Patent, Dr. Moini has been involved in catalyst research for
`
`more than twenty years, and is a named inventor on 30 U.S. patents, some of which
`
`pertain to zeolites for use as automotive catalysts. Ex. 2011 at ¶¶ 1-2.
`
`
`
`13
`
`

`
`
`
`
`
` Second, Dr. Moini is not relaying any statements by BASF customers, and
`
`therefore, his statement regarding why customers purchase the BASF product is
`
`not hearsay. As explained above, Dr. Moini is clearly qualified to offer testimony
`
`as to why customers would purchase the CuCHA catalyst given his extensive
`
`knowledge and experience with zeolite catalysts.
`
`
`
`Finally, Dr. Moini’s testimony has relevance to the issue of whether there is
`
`a nexus between the commercial success of the product and the claimed CuCHA
`
`catalyst. Dr. Moini’s testimony and Dr. Tsapatsis’ testimony demonstrate that the
`
`product sold by BASF falls within the scope of the claims of the 662 Patent. Ex.
`
`2018 at ¶¶ 175-177. Furthermore, Dr. Moini’s testimony shows that the
`
`commercial success of the product is due to the properties of the CuCHA material
`
`(and not, for example, due to the nature of the substrate).
`
`V. MOTION TO EXCLUDE PARAGRAPH ¶ 7 OF SCHMIDT
`DECLARATION (EX. 2034)
`
`
`
`Petitioner moves to exclude ¶ 7 of the Schmidt declaration (Ex. 2034) on the
`
`grounds of relevance and hearsay. The testimony by Ms. Schmidt about the level
`
`of BASF sales was based on her personal knowledge of data that is maintained in
`
`various databases at BASF. This testimony is not hearsay. Furthermore, if
`
`Petitioner’s objection to the evidence is based on its belief that it was denied the
`
`ability to inspect the databases underlying Ms. Schmidt’s testimony, the objection
`
`has been waived. Patent Owner received Ms. Schmidt’s declaration on February
`
`
`
`14
`
`

`
`
`
`12, 2016, and did not seek discovery of the underlying databases, nor would
`
`inspection of such databases fall within the scope of “routine discovery” under 37
`
`C.F.R. § 42.51(b). Any belated desire to inspect the databases is not a basis on
`
`which to exclude Ms. Schmidt’s testimony.
`
`
`
`Petitioner also contends that the testimony should be excluded on the
`
`grounds of relevance because Ms. Schmidt was instructed not to testify regarding
`
`the market share split between BASF and its licensee, Johnson Matthey. As is
`
`clear from the deposition transcript, Ms. Schmidt could not testify to that split
`
`without violating confidentiality provisions of the license agreement between
`
`BASF and Johnson Matthey. Ex. 1120 at 22:1-24:16. Thus, Petitioner’s objection
`
`based on relevance is improper. Ms. Schmidt’s testimony about the total market
`
`share for CuCHA catalysts is clearly relevant to the issue of commercial success.
`
`FRE 401. In addition, Petitioner is incorrect that Patent Owner has not provided
`
`any information from which to determine whether Johnson Matthey makes a
`
`CuCHA catalyst that falls within the scope of the 662 claims. Patent Owner has
`
`produced evidence that Johnson Matthey is a licensee of the 662 Patent and
`
`provided the combined CuCHA total market share owned by Patent Owner and its
`
`licensee, Johnson Matthey.
`
`
`
`For the reasons stated above, respectfully requests that Petitioner’s motion to
`
`exclude should be denied in its entirety.
