`
`PETITIONER’S MOTION TO EXCLUDE
`__________________________________________________________________
`
`

`
`Pursuant to 37 C.F.R. § 42.64, Petitioner Umicore AG & CO. KG
`
`(“Umicore”) hereby respectfully moves to exclude the following evidence offered
`
`by Patent Owner BASF Corp. (“BASF”): (1) Paragraphs 28, 48, 54-55, 62-71, 79,
`
`147-150, and 168-177 of the Declaration of Dr. Michael Tsapatsis (Ex. 2018); (2)
`
`Paragraph 11 of the February 12, 2016 Declaration of Dr. Ahmad Moini (Ex.
`
`2019); and (3) Paragraph 7 of the Declaration of Olivia Schmidt (Ex. 2034).
`
`Umicore filed and served a paper setting forth the grounds for its objections to
`
`these paragraphs on February 19, 2016. (See Paper 28.) BASF did not serve any
`
`supplemental evidence or otherwise respond to the objections.
`
`Much like BASF’s response, the Tsapatsis, Moini, and Schmidt declarations
`
`focus on unclaimed features, ignore key facts, and fail to include necessary
`
`foundational evidence. Further, each of the witnesses avoid expressing certain
`
`opinions themselves and instead improperly rely on uncross-examined statements
`
`of others in violation of the hearsay rules. For the reasons set forth below,
`
`exclusion of the above identified paragraphs is appropriate under Federal Rules of
`
`Evidence 402, 602, 702, 703, or 802.
`
`I.
`
`Paragraphs 28, 48, 54-55, 62-71, 79, 147-150, and 168-177 of the
`Tsapatsis Declaration (Ex. 2018)
`
`BASF has submitted an expert declaration of Dr. Tsapatsis (Ex. 2018) in
`
`response to Umicore’s showing of prima facie obviousness of the ’203 patent.
`
`Federal Rule of Evidence 702 requires an expert’s opinions to be “based on
`
`-1-
`
`

`
`sufficient facts or data.” While Rule 703 provides that an expert may rely on
`
`otherwise inadmissible materials, he may do so only “[i]f experts in the particular
`
`field would reasonably rely on those kinds of facts or data in forming an opinion.”
`
`Paragraphs 28, 48, 54-55, 62-71, 79, 147-150, and 168-177 of the Tsapatsis
`
`declaration violate these Rules and should be excluded.
`
`A. Dr. Tsapatsis’ Reliance on Irrelevant and Untrustworthy Hearsay
`
`The Tsapatsis declaration cites to declarations submitted during
`
`reexamination of the ’662 patent (the parent of the ’203 patent). This includes two
`
`declarations signed by Dr. Ahmad Moini (Exs. 2003 and 2011), a declaration
`
`signed by Pramod Ravindran (Ex. 2004), a declaration signed by Stacey Zones
`
`(Ex. 2009), and a declaration signed by Stanley Roth (Ex. 2001). These
`
`declarations are not the type of evidence that can be reasonably relied on to support
`
`expert opinions. Paragraphs 28, 48, 79, 170, and 174 of the Tsapatsis declaration
`
`should all be excluded under Rules 702 and 703.
`
`1.
`
`Opinions Based on the Moini Declarations
`
`In paragraph 28, Dr. Tsapatsis cites to a passage in a February 9, 2011 Moini
`
`declaration stating that the inventors of the ’662 and ’203 patents purportedly
`
`“screen[ed] over 900 zeolite materials including over twelve different structure
`
`types.” (Ex. 2003, Moini declaration at ¶ 4; see also Ex. 2018, Tsapatsis
`
`declaration at ¶ 28.) According to Dr. Tsapatsis, this shows that the patent’s
`
`-2-
`
`

`
`subject matter did not entail “routine optimization that was predictable based on
`
`prior art teachings.” (Id.)
`
`First, Dr. Tsapatsis opinion relating to the Moini declaration is irrelevant
`
`under Rule 402. Whether or not the inventors of the ’662 and ’203 patents
`
`themselves engaged in a large amount of work when developing BASF’s
`
`commercial catalyst product has no bearing on obviousness. See generally KSR
`
`Int’l Co. v. Teleflex Inc., 550 US 398, 406-407 (2007); see also Life Techs., Inc. v.
`
`Clontech Labs., Inc., 224 F.3d 1320, 1325 (Fed. Cir. 2000) (“[T]he path that leads
`
`an inventor to the invention is expressly made irrelevant to patentability by
`
`statute.”). Instead, the relevant question is whether one of ordinary skill in the art
`
`would have considered the broadly claimed subject matter of the ’203 patent to be
`
`a predictable variation of known prior art catalysts. Further, there is no evidence in
`
`the record indicating that the testing of “900 zeolite materials” and “twelve
`
`different structure types” was directed to any problem solved by the claims of the
`
`’203 patent, as opposed to work directed generally to zeolite development. There
`
`is also no evidence in the record that any work leading to the claimed invention
`
`constituted a large amount of work (as opposed to just a routine volume of
`
`laboratory screening conducted by catalyst companies like BASF). Second, such a
`
`statement in an uncross-examined declaration submitted by an advocate during
`
`patent prosecution is not the type of material experts in the field would rely on in
`
`-3-
`
`

`
`forming opinions on obviousness. Moreover, Dr. Tsapatsis never discussed this
`
`issue with Dr. Moini. Paragraph 28 of the Tsapatsis declaration should be
`
`excluded under Rules 402 and 702.
`
`In paragraph 174, Dr. Tsapatsis also cites another declaration signed by Dr.
`
`Moini and dated December 18, 2011 (Ex. 2011) to support arguments regarding
`
`unexpected results. (See, e.g., Ex. 2018, Tsapatsis Declaration at ¶ 174.) This
`
`declaration discussed the purported experimental testing of “two examples from
`
`Dedecek.” (Ex. 2011, Moini Declaration at ¶¶ 4-12.) But, Dr. Moini was “not able
`
`to obtain natural chabazite samples” identical to those discussed in Dedecek, and
`
`instead employed substitute materials with different percentages of silica and
`
`alumina (and thus a different SAR). (See id. at ¶ 5.) In other words, Dr. Moini did
`
`not test Dedecek’s examples. He tested something different.
`
`Later in this same December 2011 declaration, Dr. Moini attempts to
`
`compare the prior art samples he tested with “additional Examples representative
`
`of the ‘662 invention.” (Id. at ¶ 25.) But, rather than discussing examples he
`
`himself prepared and tested, Dr. Moini discusses only “data from a colleague.”
`
`(Id.) Dr. Moini provides no indication of who this “colleague” might be, whether
`
`this “colleague” was qualified to synthesize catalysts or perform the described
`
`tests, and how the data he reports was collected and maintained. Thus, all of Dr.
`
`-4-
`
`

`
`Moini’s discussion of the “additional Examples representative of the ‘662
`
`invention” is inadmissible hearsay.
`
`Since Dr. Moini did not actually test the prior art and provides only hearsay
`
`accounts of the testing of the ’662 patent’s (or ’203 patent’s) materials, it was
`
`improper for Dr. Tsapatsis to rely on this testimony in concluding that “the
`
`hydrothermal stability of the claimed CuCHA catalyst is unexpected.” Paragraph
`
`174 should be excluded under Rules 702 and 703.
`
`2.
`
`Opinions Based on the Ravindran Declaration
`
`In paragraph 48, Dr. Tsapatsis cites the Ravindran declaration to argue that a
`
`2008 paper authored by employees of Ford is actually discussing a BASF catalyst
`
`product. (See Ex. 2018, Tsapatsis Declaration at ¶ 48.) According to BASF, the
`
`paper shows that BASF’s catalyst has “remarkable high temperature hydrothermal
`
`stability.” (Id.) The Ford paper does not mention BASF. Instead, it merely
`
`references “Cu/zeolites” without providing any indication of their source or
`
`composition. (See Ex. 2002 at 001-003.)
`
`The Ravindran declaration discusses the preparation and labeling of various
`
`BASF catalyst samples alleged to be provided to Ford under “a secrecy
`
`agreement.” (Ex. 2004, Ravindran Declaration at ¶¶ 4-7.) There is no discussion
`
`of what Ford did with the samples once it received them. The declaration states
`
`that Mr. Ravindran received an “e-mail” from Ford that “confirmed that the sample
`
`-5-
`
`

`
`referred to in the Ford SAE publication” was a BASF sample. (Id. at ¶ 8.) But,
`
`Mr. Ravindran does not attach the referenced email to his declaration, or identify
`
`the sender. Thus, Dr. Tsapatsis is using the out of court statements of an unnamed
`
`Ford witness in an attempt to prove the truth of the matter asserted: that the Ford
`
`paper discusses BASF’s CuCHA catalyst product. This is hearsay. And, BASF
`
`has made no attempt to show that any of the hearsay exceptions apply.
`
`Compounding this issue, Dr. Tsapatsis has not had a discussion with Mr.
`
`Ravindran or anyone at Ford. (See Ex. 1119, Tsapatsis Depo. at 34:8-21.) Thus,
`
`he had no way to properly assess the reliability of the hearsay. Paragraph 48 of Dr.
`
`Tsapatsis’ declaration should be excluded under Rules 702 and 703.
`
`3.
`
`Opinions Based on the Zones Declaration
`
`In paragraph 79, Dr. Tsapatsis cites a reexamination declaration signed by
`
`Stacey Zones in support of an argument that one of Umicore’s prior art
`
`references—US 6,709,644 to Zones—directs one of ordinary skill in the art to use
`
`the reference’s materials for other catalytic reactions besides ammonia SCR. (Ex.
`
`2018, Tsapatsis Declaration at ¶ 79.) This is entirely irrelevant. Dr. Zones’ own
`
`after-the-fact characterization of what he meant by certain statements in his prior
`
`art patent cannot serve to change the express disclosure of that patent to one of
`
`ordinary skill in the art. See, e.g., See, e.g., Innogenetics, N.V. v. Abbott Labs., 512
`
`F.3d 1363, 1375 (Fed. Cir. 2008) (affirming exclusion of technical testimony by
`
`-6-
`
`

`
`prior art inventor). The Zones declaration is also inadmissible hearsay. Dr. Zones
`
`is not associated with BASF and was not made available for deposition. Thus,
`
`paragraph 79 of the Tsapatsis declaration should be excluded under Rules 702 and
`
`703.
`
`4.
`
`Opinions Based on the Roth Declaration
`
`In paragraph 170, Dr. Tsapatsis cites a declaration signed by Dr. Stanley
`
`Roth (Ex. 2001) and argues that it shows that there was “skepticism” regarding the
`
`“commercial viability of Cu-zeolites.” (Ex. 2018, Tsapatsis Declaration at ¶ 170.)
`
`The Roth declaration, however, is replete with inadmissible hearsay. Dr. Roth’s
`
`declaration references a 2005 email chain between a university professor and a
`
`DOE researcher that purportedly represents “the view of … those skilled in the art
`
`that Cu-Zeolites could not be used as catalysts for the SCR of NOx because of the
`
`inability to maintain NOx conversion upon exposure to hydrothermal conditions.”
`
`(Ex. 2001 at 003.) But, neither the university professor nor the DOE researcher are
`
`identified. And, neither of these individuals has submitted a declaration in this
`
`IPR. Further, Dr. Roth himself contradicts the views expressed by both the
`
`professor and researcher when he notes that “[i]n the zeolite literature there are
`
`probably many examples of structures with hydrothermal durability to the 700-800
`
`oC range. The big issue appears to be your DOE reviewers that have experience
`
`limited to the Cu-ZSM5 HC-SCR example, where catalytic performance quickly
`
`-7-
`
`

`
`died after modest hydrothermal aging.” (Id. at 007.) In view of this, it was
`
`inappropriate for Dr. Tsapatsis to rely on such inadmissible and internally
`
`contradicted statements in the Roth declaration to support his own conclusions
`
`regarding alleged “skepticism.” Paragraph 170 should be excluded under Rules
`
`702 and 703.
`
`B. Reliance on Irrelevant Unclaimed Features
`
`The Tsapatsis declaration focuses repeatedly on irrelevant and unclaimed
`
`catalyst features. For instance, in paragraphs 54-55 Dr. Tsapatsis argues that the
`
`claims of the ’662 patent (which is related to the ’203 patent) should be construed
`
`to require “the properties that are described in the specification.” (Ex. 2018,
`
`Tsapatsis Dec. at ¶¶ 54-55.) Dr. Tsapatsis goes on to argue in paragraphs 62-71
`
`that the materials of the ’662 and ’203 patents are different from the prior art
`
`identified by Umicore because they “solve[]” a problem with prior art materials by
`
`providing “low temperature SCR activity and/or improved hydrothermal
`
`durability.” (Id. at ¶¶ 62-71.) And, in paragraphs 168-177, Dr. Tsapatsis argues
`
`that the “hydrothermal stability” of the ’662 and ’203 patents’ materials overcame
`
`skepticism, produced unexpected results, and gave rise to commercial success. (Id.
`
`at ¶¶ 168-177.)
`
`As explained in Umicore’s reply brief, none of the ’203 patent claims at
`
`issue in this IPR require either “low temperature SCR activity” or “improved
`
`-8-
`
`

`
`hydrothermal durability.” (See Umicore’s Reply, Paper 36 at 3-10.) The ’203
`
`patent’s specification also includes examples that have the CHA crystal structure,
`
`along with SARs and Cu/Al ratios within the claimed ranges—and thus fall within
`
`the scope of the ’203 patent’s broadest claims—but admittedly do “not show
`
`enhanced resistance to thermal aging.” (Ex. 1101, ’203 patent at 11:21-26.)
`
`Moreover, the ’203 patent repeatedly states that it is the presence of “free
`
`copper”—also not required by the claims—that purportedly results in improved
`
`hydrothermal stability. (See id. at 2:31-35; 2:65-3:3; 5:33-39; 5:51-54; see also
`
`11:35-37; 11:55-58; 12:4-8.)
`
`An unclaimed feature or property “is immaterial to obviousness of [a]
`
`composition … in light of the prior art showing general efficacy for the same use.”
`
`Tyco Healthcare Grp. v. Mut. Pharm. Co., 642 F.3d 1370, 1374 (Fed. Cir. 2011).
`
`Here, Umicore’s prior art discloses catalysts with the CHA crystal structure and
`
`Cu/Al ratios and SARs overlapping the claimed ranges. This same prior art also
`
`explains that these catalysts can be used as SCR catalysts to reduce nitrogen oxides
`
`in diesel engine exhaust. (See generally Umicore Petition, Paper 1.) This is all the
`
`’203 patent’s claims require. Thus, Dr. Tsapatsis’ repeated references to
`
`unclaimed performance features in paragraphs 54-55, 62-71, and 168-177—
`
`including improved hydrothermal stability and low temperature SCR activity—are
`
`irrelevant to the obviousness question and should be excluded under Rule 402.
`
`-9-
`
`

`
`C. Utilization of Unreliable Principles to Assess Dr. Schuetze’s Data
`
`Paragraphs 147-150 of the Tsapatsis declaration discuss certain of the
`
`experimental testing performed by Dr. Schuetze in support of Umicore’s IPR
`
`petition. (See Ex. 2018, Tsapatsis declaration at ¶¶ 147-150.) According to Dr.
`
`Tsapatsis, Dr. Schuetze’s data shows that “there is an improvement in performance
`
`between” a Cu/Al ratio of “0.15 and 0.245.” (Id. at ¶ 148.) Dr. Tsapatsis then
`
`concludes that this means that “the 0.25 Cu/Al ratio has significance.” (Id.) But,
`
`Dr. Tsapatsis does not consider the data collected by Dr. Schuetze in its entirety.
`
`The totality of the data actually shows that while performance does increase
`
`between a Cu/Al ratio of 0.15 and 0.245, it does so in a steady fashion with no
`
`unexpected or large jump in performance when the lower bound of the ’203
`
`patent’s claimed Cu/Al ratio range is crossed. (See Ex. 1108, Lercher declaration
`
`at ¶¶ 381-394.) Dr. Tsapatsis’ testimony, which is based on isolated testing points,
`
`is not “the product of reliable principles and methods” and thus should be excluded
`
`under Rule 702. Further, the mere fact that there is an “increase” in performance
`
`does not mean that the claimed ranges are “critical.” See In re Soni, 54 F.3d 746,
`
`751 (Fed. Cir. 1995); see also Golderma Lab., LP v. Tolmar, Inc., 737 F.3d 731,
`
`739 (Fed. Cir. 2013). Dr. Tsapatsis’ failure to address whether the claimed ranges
`
`of Cu/Al ratios and SARs produce results that are different in some meaningful
`
`-10-
`
`

`
`way than those achieved by the prior art (as opposed to just being marginally
`
`better) render his opinions irrelevant under Rule 402.
`
`II.
`
`Paragraph 11 of the Moini Declaration
`
`Paragraph 11 of the Moini declaration (Ex. 2019) is inadmissible and must
`
`be excluded under Rules 402, 602, 702, and 802. BASF cites to the Moini
`
`declaration in an effort to show that “excellent activity over a wide temperature
`
`range and excellent hydrothermal stability” give rise to the purported commercial
`
`success of BASF’s CuCHA catalyst products. (See BASF Response Brief, Paper
`
`26 at 43-44.) However, Dr. Moini’s declaration discusses the “product
`
`specification for the commercially available CuCHA catalyst sold by BASF,” and
`
`not the actual performance of the products as sold. (Ex. 2019 at ¶¶ 4-10.) Dr.
`
`Moini also states—without any explanation or supporting context—that
`
`“customers who purchase the CuCHA catalyst product do so because of the
`
`excellent properties of CuCHA material coated on the substrate.” (Id. at ¶ 11.) Dr.
`
`Moini’s unsupported, speculative testimony regarding why customers purchase
`
`BASF’s products is inadmissible and should be excluded.
`
`Dr. Moini is “employed by BASF as a scientist.” (Id. at ¶ 1; see also Ex.
`
`2003 at ¶¶ 1-2; Ex. 2011 at ¶¶ 1-2.) While this technical background could make
`
`Dr. Moini knowledgeable about the composition of BASF’s catalysts and its
`
`research efforts, there is no indication in the record that he has any involvement
`
`-11-
`
`

`
`with the marketing of BASF’s products. Likewise, BASF has presented no
`
`evidence or other testimony showing that Dr. Moini interacts (directly or
`
`indirectly) with BASF’s customers. Rule 602 provides that a fact witness’s
`
`testimony must be based on his own personal knowledge. Rule 702 provides that
`
`an expert must have technical, scientific or specialized knowledge that will help
`
`the trier of fact to understand the evidence. An expert’s opinions must also be
`
`based on sufficient facts or data. Here, BASF has presented no evidence showing
`
`that Dr. Moini is sufficiently knowledgeable or qualified to offer either fact or
`
`opinion testimony regarding why BASF’s customers purchase its products. Absent
`
`this necessary foundational evidence, Dr. Moini’s unsupported statements in
`
`paragraph 11 must be excluded.
`
` Next, while there is no indication that this is the case, even if paragraph 11
`
`of Dr. Moini’s declaration is simply meant to relay statements made by BASF’s
`
`customers to Dr. Moini, it would still be inadmissible. No BASF customers who
`
`have made comments similar to that in paragraph 11 of the Moini declaration have
`
`been identified. And, no documents have been produced by BASF reflecting
`
`customer comments. Thus, Dr. Moini and BASF would be improperly attempting
`
`to rely on the alleged out of court statements of BASF’s customers to prove why
`
`those customers are buying BASF’s products. This is hearsay. Exclusion under
`
`Rule 802 is appropriate.
`
`-12-
`
`

`
`Last, Dr. Moini’s testimony is irrelevant under Rule 402. As noted above,
`
`BASF points to this testimony in an effort to show that its CuCHA product is
`
`commercially successful because of its “excellent activity over a wide temperature
`
`range and excellent hydrothermal stability.” But, none of the ’203 patent’s claims
`
`require catalysts with these properties. Instead, the claims embrace any catalyst
`
`with a SAR and Cu/Al ratio falling within the claimed ranges that is “effective to
`
`promote the reaction of ammonia with nitrogen oxides to form nitrogen and H2O
`
`selectively.” Dr. Moini’s testimony relates to unclaimed features and lacks the
`
`nexus with the claimed subject matter that is required to render it relevant to the
`
`obviousness analysis.
`
`III. Paragraph 7 of the Schmidt Declaration
`
`Paragraph 7 of the Schmidt declaration (Ex. 2034) is inadmissible and
`
`should be excluded under Rules 402 and 802. BASF cites to this particular
`
`paragraph in an effort to show the share of the SCR catalyst market satisfied by its
`
`own CuCHA catalyst product. (See BASF Response Brief, Paper 26 at 44-45.)
`
`In this paragraph, Ms. Schmidt references “internal data” of BASF relating
`
`to the “sales of CuCHA catalysts” and “estimates regarding the sales by BASF
`
`licensees.” (Ex. 2034 at ¶ 7.) BASF is relying on the data to establish the truth of
`
`the matter asserted: BASF’s level of sales. This is hearsay.
`
`-13-
`
`

`
`BASF has also not established that any of the hearsay exceptions apply.
`
`While Ms. Schmidt states that the “numbers” in her declaration are “maintain[ed]
`
`in the ordinary course of business” (see Ex. 2034 at ¶ 8), no other information is
`
`provided. None of this data was attached to Ms. Schmidt’s declaration or
`
`otherwise made available by BASF. And, there is no explanation regarding how
`
`the “internal data” of BASF’s sales and “estimates” of BASF’s licensees’ sales are
`
`generated. Ms. Schmidt also does not explain who collects this data, or when it is
`
`recorded by BASF. When Umicore attempted to obtain further details regarding
`
`the data during deposition, BASF blocked questioning. (See, e.g., Ex. 1120, April
`
`29, 2016 Schmidt Depo. at 22:1-6.) This information was required to properly
`
`assess whether any of the exceptions Rule 803 apply. Absent this, paragraph 7 of
`
`Ms. Schmidt’s declaration must be excluded.
`
`Paragraph 7 of Ms. Schmidt’s declaration is also irrelevant. The market
`
`share data in this paragraph includes the sales of both “BASF CuCHA catalysts”
`
`and the catalysts of “BASF licensees.” (Ex. 2034 at ¶ 7; see also Ex. 1120,
`
`4/29/16 Depo. of Olivia Schmidt at 14:17-15:6, 16:14-20; 21:20-25.) But, BASF
`
`has not provided any information at all about its licensees’ products, let alone
`
`information sufficient to determine if those products fall within the scope of the
`
`’203 patent’s claims. BASF has also refused to identify what portion of the market
`
`share data reported by Ms. Schmidt is accounted for by BASF’s CuCHA catalyst
`
`-14-
`
`

`
`(the only product that BASF compares to the claims). (See id. at 22:1-24:16.)
`
`These evidentiary deficiencies render the market share number reported by Ms.
`
`Schmidt meaningless. As a result, paragraph 7 is irrelevant by BASF’s own
`
`making and should be excluded.
