`
`Introduction
`
`Petitioner submits the following Reply to Patent Owner’s Response
`
`(“Response”) filed by Infineum. For the reasons discussed below, the Board
`
`should cancel the claims of U.S. Patent No. 8,076,274.
`
`
`
`II. The ‘274 Patent Employs Antioxidants to Address the Oxidation of
`
`Magnesium Detergents
`
`Infineum characterizes the ‘274 Patent as teaching lubricating oil
`
`compositions that “make beneficial use of the alkalinity of magnesium containing
`
`detergents while minimizing ash formation and avoiding the bore polishing of
`
`engine components commonly associated with use of magnesium compounds.”
`
`[Response, p.1]. But such compositions were already well-known. For example,
`
`magnesium detergents and antioxidants are well-known as even Infineum admits.1
`
`[Ex.1046, p.142:4-13]. It was also known prior to the ‘274 Patent that magnesium
`
`detergents contribute less SASH than other detergents, such as calcium detergents.
`
`[Ex.1018, p.295]. Moreover, magnesium was known to cause bore polishing and
`
`
`
`1 Magnesium detergents and antioxidants are widely used. [Exs.1040-1042;1044].
`
`
`
`-1-
`
`
`
`Case No. IPR2017-01321
`
`the mechanism was well-documented. [Exs.1023;1001, 3:44-48].2 Finally, it was
`
`common knowledge that oxidation led to decreased engine performance, e.g.,
`
`increased oil consumption. [Exs.1024, p.52;1046, p.103:5-15]. In light of these
`
`known associations and mechanisms, skilled formulators would have two
`
`strategies to counteract the oxidation of magnesium: (1) eliminate the magnesium
`
`detergent (and lose the known associated benefits of lower SASH ) or (2) use an
`
`antioxidant to mitigate oxidation. [Ex.1043, p.157].
`
`To the extent Infineum argues that there remain slight discrepancies between
`
`the prior art disclosures and the challenged claims, any changes would be obvious
`
`to a POSITA. Heavy-duty diesel formulators regularly consider industrial
`
`standards, such as ACEA-2004, to develop commercial formulations. [Ex.1004,
`
`¶37]. Thus, there is a natural motivation to develop lubricants that meet these
`
`standards. [Ex.1046, p.89:6-14]. The ‘274 Patent uses known components, i.e.,
`
`magnesium detergents and antioxidants, in known ways, for known reasons to
`
`achieve a SASH limit that meets industry standards.
`
`
`
`2 A POSITA would have been aware that prior to the ‘274 Patent the oxidation of
`
`magnesium detergents, which forms periclase, contributes to bore polish.
`
`[Exs.1004, ¶¶38-42;1023, p.352;1038, p.201;1043, p.156;1046, p.104:2-17].
`
`
`
`-2-
`
`
`
`Case No. IPR2017-01321
`
`
`
`III. Ground 1:Colclough Anticipates Claims 1-11
`
`Ground 1 shows that Claims 1-11 of the ‘274 Patent are anticipated by
`
`Colclough. [Petition, pp.26-34].
`
`It is undisputed that examples V and VI of Colclough teach the magnesium
`
`detergents and antioxidants in Claim 1. And it is undisputed that Petitioner’s
`
`testing of examples V and VI reveal SASH values within the claim range.
`
`[Ex.1006, ¶¶29&46]. Infineum’s central argument is that the Board (1) should
`
`disregard the clear and unambiguous teachings in Colclough that Component G -
`
`an aminic antioxidant - is used in an amount of 0.4 wt.% and (2) improperly shifted
`
`the burden to Infineum.
`
`A. Component G of Colclough is Used at 0.4 wt.%
`
`No amount of obfuscation by Infineum can change the fact that Colclough
`
`clearly states that component G is “an alkylated diphenylamine antioxidant…” and
`
`that Colclough discloses examples using component G at 0.4 wt.%. [Ex.1007,
`
`p.7:5; p.8:1-67]. Infineum’s central argument rests on an attempt to inject
`
`ambiguity into Colclough’s disclosure where none exists. For example, Infineum
`
`argues that because Colclough provides an example commercial source for the
`
`alkylated diphenylamine antioxidant, and that one could (without justification)
`
`
`
`-3-
`
`
`
`Case No. IPR2017-01321
`
`question the purity of the commercial component, that Colclough’s examples
`
`somehow do not teach the claimed limitation. [Response, p.17].
`
`However, Colclough discloses that component G is an “alkylated
`
`diphenylamine commercially available as Irganox L-57 by Ciba Geigy.” Rather
`
`than taking the explicit disclosure of component G (0.4 wt.% alkylated
`
`diphenylamine), Infineum attempts to re-write Colclough’s disclosure to read 0.4
`
`wt.% of Irganox L-57. But that is not what Colclough discloses. Infineum’s aim is
`
`clear: to create ambiguity by introducing irrelevant speculation on Irganox L-57.
`
`Infineum’s attempts to obfuscate Colclough’s clear teachings should be rejected.
`
`B.
`
`Petitioner Tested SASH of Colclough Using the Identified
`
`Commercial Product
`
`Petitioner has proved that examples V and VI of Colclough have SASH
`
`values within the claimed range of 0.6 to 2.0 mass%. Mr. Styer prepared these
`
`examples using 0.4 wt.% of Irganox L-57, a commercially available source of
`
`alkylated diphenylamine. [Ex.1006, ¶¶17&34]. After making the examples in
`
`Colclough, per Colclough’s clear teachings, testing of the samples revealed SASH
`
`values squarely within the claims.
`
`C. Burden of Production, Not Patentability, Shifted to Infineum
`
`Infineum argues that the Board improperly shifted the burden to Patent
`
`
`
`-4-
`
`
`
`Case No. IPR2017-01321
`
`Owner. [Response, p.18]. But the Board did no such thing. Rather, the Board
`
`shifted the burden of production, a distinct and shifting burden, to Infineum, which
`
`is entirely proper here. Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316,
`
`1326–27 (Fed. Cir. 2008).
`
`1. Infineum Fails the Burden of Production
`
`Infineum cannot meet its burden because Colclough is clear the alkylated
`
`diphenylamine antioxidant, component G, is used at 0.4 wt.%. [Ex.1007, p.7:5].
`
`This teaching is not a presumption as Infineum attempts to cast it. It is an express
`
`teaching of an explicit amount of an ingredient. Because of this clear teaching, the
`
`burden of production properly shifts to Infineum.
`
`Furthermore, Infineum cannot meet its burden of production because (a)
`
`Colclough’s teaching is clear, (b) Infineum’s attempted re-write of Colclough’s
`
`disclosure is factually and legally incorrect, and (c) Infineum’s supposed
`
`contradictory evidence is deficient as discussed further below. Rather than an
`
`alleged failure of proof by Petitioner, it is Infineum who has failed to meet its
`
`burden.
`
`2. Diluted Components Clearly Indicated in Colclough
`
`Infineum attempts to inject confusion by arguing that commercially
`
`available components could be diluted. However, when components are diluted,
`
`
`
`-5-
`
`
`
`Case No. IPR2017-01321
`
`Colclough explicitly states that the component is diluted – as it did with respect to
`
`components A, B, C, D, F, H, and L. [Ex.1007, p.6:59-p.7:13]. Accordingly, based
`
`on the explicit disclosure in Colclough, component G cannot represent a dilution.
`
`[Ex.2027, p.142:10-p.145:21]. A POSITA would understand that the amount in
`
`Table 1 is 0.4 wt.% of an alkylated diphenylamine antioxidant. There is no reason,
`
`based on Colclough, to use less than 0.4 wt.% of an alkylated diphenylamine
`
`antioxidant.
`
`3. MSDS Component Ranges Cannot Support Infineum’s
`
`Assertions
`
`In a last ditch effort to create ambiguity, Infineum argues that Irganox L-57
`
`would not provide the required amount of alkylated diphenylamine by relying on
`
`latter publications and non-technical specifications in support of its argument.3
`
`[Response, p.24]. But even the evidence used by Infineum for this legally and
`
`factually incorrect argument is deficient. For example, Exhibits 2014, 2017, and
`
`2018 were published after 2006 and if not excluded, should be given no weight in
`
`
`
`3 Exhibits 2019 and 2020 are related to a different product, Irganox 5057.
`
`[Ex.2026, p.59:18-23].
`
`
`
`-6-
`
`
`
`Case No. IPR2017-01321
`
`these proceedings.4 Moreover, Infineum relies on Material Safety Data Sheets
`
`(MSDS) for the proposition that Irganox L-57 could contain something else. But
`
`Infineum’s reliance on an MSDS is misplaced. First, Infineum relies on an MSDS
`
`published after 2009, which is three years after the relevant date. [Ex.2025, ¶48].
`
`Setting that aside, MSDS are not technical specifications that one would rely on for
`
`precise disclosures of component concentrations. [Exs.2026, p.54:25-
`
`p.55:14&p.92:16-p.93:5;2027, p.36:19-p.37&p.139:24-141:25]. In fact, OSHA
`
`regulations explicitly provide exceptions for component concentrations and
`
`explicitly allow for the use of ranges.5 29 C.F.R. §1910.1200, Table-D.1 (2012).
`
`Even Infineum’s own expert was aware of this fact, yet continued to rely on the
`
`MSDS. [Ex.1046, p.115:19-24]. Thus, the conclusions drawn by Infineum that the
`
`ranges in the MSDS indicate something other than alkylated diphenylamine are not
`
`supported by the OSHA regulations. Infineum’s reliance on the MSDS is both
`
`misplaced and improper.
`
`
`
`4 Infineum did not even bother to indicate a publication date of Exhibit 2024,
`
`which could not have been published before 2017.
`
`5 Exceptions allow ranges for trade secrets, batch variability, and substantially
`
`similar chemical compounds.
`
`
`
`-7-
`
`
`
`Case No. IPR2017-01321
`
`D.
`
`Infineum’s Other Arguments are Without Merit
`
`Infineum also raises a hodge-podge of criticism regarding Colclough that
`
`merely attempts to obfuscate Colclough’s clear anticipation. For example,
`
`Infineum argues that Colclough is “decades old.” [Response, p.2]. But, a reference
`
`is no less anticipatory because it is old. In re Rosenberger, 116 F.2d 507, 511
`
`(C.C.P.A. 1941). Then, Infineum argues that Colclough is “directed to solving
`
`fundamentally different problems” than the ‘274 Patent and that Colclough “is not
`
`concerned with the amount of sulfated ash produced by its compositions.”
`
`[Response, pp.2&13]. However, as the Board correctly found, these arguments
`
`have “no bearing on the question of anticipation.” [Paper 8, p.12; Celeritas Techs.,
`
`Ltd. v. Rockwell Int’l Corp., 150 F.3d 1354, 1361 (Fed. Cir. 1998)]. Finally,
`
`Infineum appears to take the position that Colclough’s disclosures were merely
`
`“accidental or coincidental”. [Response, p.2]. Again, an inapplicable defense to
`
`Coclough’s anticipating examples because it was well-known that magnesium
`
`contributed to bore polishing.
`
`IV. Ground 2:Nicholson in view of ACEA-2004 Renders Claims 1-12
`
`Obvious
`
`Petitioner’s Ground 2 details how Claims 1-12 of the ‘274 Patent would
`
`have been prima facie obvious to a POSITA at the time of the invention over
`
`
`
`-8-
`
`
`
`Case No. IPR2017-01321
`
`Nicholson in view of the ACEA 2004 Sequences (“ACEA-2004”). [Petition,
`
`pp.34-45].
`
`A. Example IV of Nicholson Invalidates Claims 1-12
`
`Nicholson’s Example IV, teaches all the features of Claim 1, except it does
`
`not explicitly state the amount of magnesium metal delivered by a 400 TBN
`
`magnesium alkylbenzene sulphonate detergent used at 2.28 wt.%. [Petition, p.34].
`
`However, Petitioner has shown that the 400 TBN detergent in Example IV would
`
`deliver an claimed amount of magnesium. [Ex.1004, ¶64]. Moreover, Nicholson
`
`Example IV in combination with ACEA-2004 would lead POSITA to a
`
`combination of additives that would render obvious all of the claims of the ‘274
`
`Patent. [Petition, ¶¶36-39].
`
`1. Petitioner’s Evidence is Unrebutted
`
`The Petitioner remade Nicholson’s Example IV and tested for SASH content
`
`using the standard specified in Claim 1 and measured magnesium. [Petition, ¶¶36-
`
`38]. Neither Infineum nor its expert has submitted any contrary evidence for the
`
`test results of Example IV.
`
`2. Motivation to Combine Nicholson and ACEA-2004
`
`At the time of filing of the ‘274 Patent, POSITA would be motivated to
`
`manufacture a heavy-duty lubricant capable of meeting the requirements of the
`
`
`
`-9-
`
`
`
`Case No. IPR2017-01321
`
`ACEA-2004. [Petition, p.41;Ex.1004, ¶125]. POSITA would know that in order to
`
`meet the requirements of ACEA-2004 a heavy-duty lubricant would have to
`
`possess good seal performance, including AK6 fluoroelastomer seal compatibility.
`
`[Ex.1012, pp.13-14]. A HDD lubricant formulator would look at the prior art and
`
`find Nicholson which teaches lubricant compositions, including Example IV,
`
`which have “excellent fluoroelastomer seal performance” on AK6 fluoroelastomer
`
`seal materials. [Ex.1009, p.14:12-15].
`
`A POSITA would also know that in addition to good seal performance, the
`
`ACEA-2004 mandated low SASH requirements of below 2.0% (E7) and 1% (E6).
`
`[Petition, p.39]. Accordingly, POSITA would particularly look to Example IV of
`
`Nicholson because it is an example that uses the lighter and less ash-producing
`
`magnesium detergent while also providing good fluoroelastomer seal performance.
`
`3. No Impermissible Hindsight
`
`Infineum argues that a combination of Nicholson and the ACEA-2004 by a
`
`POSITA would constitute impermissible hindsight. But that is simply not correct.
`
`Both Nicholson and the ‘274 Patent relate to HDD engine lubricants that meet or
`
`exceed tests relevant to industry guidelines, use similar or the same amounts of
`
`magnesium detergents and antioxidants, and have otherwise nearly identical
`
`components. [Ex.1004, ¶¶110-111]. Thus, Nicholson shows or suggest all
`
`
`
`-10-
`
`
`
`Case No. IPR2017-01321
`
`elements of the claim, contains well-understood components that have predictable
`
`results, is directly analogous to the ‘274 Patent, and complies with one or more
`
`tests of the ACEA-2004. [Petition, pp.24-25]. Moreover, both Afton’s expert and
`
`Infineum’s expert confirm that it was common and routine to follow industry
`
`specifications in developing lubricant formulations. [Exs.1004, ¶125;1046, p.89:6-
`
`14]. This proves that there is no hindsight here because it takes only a modest
`
`amount of common sense to modify analogous prior art teachings in predictable
`
`ways in view of market forces. In re McLaughlin, 443 F.2d, 1392, 1395 (C.C.P.A.
`
`1971).
`
`In fact, the ACEA-2004 points directly to the modification. First,
`
`Nicholson’s Example IV already complied with ACEA-2004’s E7 SASH limits.
`
`Thus it would have been natural to modify Nicholson to comply with the more
`
`stringent E6 SASH standard as one would simply be using a lubricant already
`
`known to pass other parts of the E7 guidelines. [Petition, p.39].
`
`Second, Nicholson and the ‘274 Patent have significant areas of overlap,
`
`which is indicative of the relatedness between the two patents. For example,
`
`Nicholson, like the ‘274 Patent, is in the field of lubricating oils. Both patents
`
`relate to HDD engines lubricants. [Ex.1004, ¶41]. Both patents relate to improving
`
`performance of HDD engines using magnesium detergents. And both patents
`
`
`
`-11-
`
`
`
`Case No. IPR2017-01321
`
`comply with one or more parts of the ACEA-2004.
`
`Accordingly, it would have been natural for a formulator looking to comply
`
`with the E6 standard of the ACEA-2004 to start with a formulation that already
`
`passed the E7 standard and a formulation that was in the same field (HDD
`
`lubricants). Moreover, Nicholson’s example would have been known to POSITA
`
`as being compliant with ACEA-2004’s fluoroelastomer seal compatibility
`
`standard, something even Infineum acknowledges. [Ex.2025, ¶64]. The
`
`materiality of this fact is that Nicholson’s Example IV would have served as a
`
`compelling starting point for complying with other parts of the ACEA-2004.
`
`Infineum complains that “[a]ll of Afton’s obviousness arguments are
`
`premised on only a single, isolated example in Nicholson.” [Response, p.26] and
`
`that the “claims of the ’274 patent do not even relate to or require any particular
`
`seal compatible dispersant.” [Response, p.3]. But these arguments are irrelevant.
`
`A “reference must be considered for everything it teaches by way of technology
`
`and is not limited to the particular invention it is describing and attempting to
`
`protect.” EWP Corp. v. Reliance Universal Inc., 755 F.2d 898, 907 (Fed. Cir.
`
`1985). Thus, disclosure of Nicholson is not limited to dispersants or problems with
`
`fluoropolymer seals, and must be considered for all that it discloses. KSR Int'l Co.
`
`v. Teleflex Inc., 550 U.S. 398 (2007) (“The idea that a designer hoping to make an
`
`
`
`-12-
`
`
`
`Case No. IPR2017-01321
`
`adjustable electronic pedal would ignore Asano because Asano was designed to
`
`solve the constant ratio problem makes little sense. A [POSITA] is also a person of
`
`ordinary creativity, not an automaton.”). And even Infineum admits that Example
`
`IV discloses a lubricating oil formulation for a test used for HDD engines.
`
`[Ex.1046, p.125:14-17]. Accordingly, Infineum’s arguments are without merit.
`
`B. Nicholson Provides a Specific Example That Meets the Broad
`
`Limitations of Claim 1
`
`Infineum states that claim 1 of the ‘274 Patent is “directed to a genus of
`
`compositions with varying amounts and types of magnesium detergent,
`
`antioxidant, and sulfated ash.” [Response, p.33]. But this argument is irrelevant
`
`because the Federal Circuit has long recognized that a genus claim encompassing
`
`even a single prior art species is unpatentable. Eli Lilly & Co. v. Barr Labs, 251
`
`F.3d 955, 971 (Fed. Cir. 2001).
`
`Moreover, Infineum’s argument that Nicholson teaches “generic and non-
`
`specific” components. [Response, pp.29-30] is similarly misguided because
`
`Nicolson teaches a specific arrangement in Example IV. [Ex.1009, p.13:36-53].
`
`The specific components include a 400 TBN overbased magnesium alkylbenzene
`
`sulfonate, sulfur-free phenolic antioxidants, and ash-free aminic antioxidants that
`
`correspond to the elements of Claim 1. [Ex.1004, Table 9]. Thus, discussion of
`
`
`
`-13-
`
`
`
`Case No. IPR2017-01321
`
`“generic” components in other parts of Nicholson is not a teaching away where
`
`there is a specific disclosure of specific components in an example.
`
`C. Age of Nicholson is not Relevant to Obviousness Combination
`
`Infineum argues that one would not have “started with a single example
`
`from a ten year old reference relating to dispersants.” [Response, p.30]. However,
`
`“[t]he mere age of the references is not persuasive of the unobviousness of the
`
`combination of their teachings.” In re Wright, 569 F.2d 1124, 1127 (CCPA 1977);
`
`see also, Iron Grip Barbell Co. v. USA Sports, Inc., 392 F.3d 1317, 1325 (Fed. Cir.
`
`2004) (holding age of reference irrelevant without secondary considerations).
`
`Nowhere has Infineum shown any long-felt need or failure of others in the art, and
`
`thus its arguments directed to age are irrelevant.
`
`D. No Teaching Away in the Cited References
`
`Infineum argues that “rather than motivating a change in Nicholson, the
`
`existence of the 2004 ACEA specification would actually deter one of ordinary
`
`skill in the art from using Nicholson’s example compositions at all.” [Response,
`
`p.31]. A teaching away, however, requires a reference to actually criticize,
`
`discredit, or otherwise discourage the claimed solution. In re Gurley, 27 F.3d 551,
`
`553 (Fed. Cir. 1994). Infineum has pointed to no portion of Nicholson or ACEA-
`
`2004 that would criticize, discredit, or otherwise discourage the combination or
`
`
`
`-14-
`
`
`
`Case No. IPR2017-01321
`
`claimed solution. Instead, Infineum argues that a POSITA would “comply with
`
`more recent standards.” [Response, p.32]. Infineum’s arguments fall well short of a
`
`teaching away. Formulators would and could consider prior formulations for
`
`meeting an industrial standard for the reasons discussed in Section IV.A.
`
`E.
`
`Infineum Cannot Base Unexpected Results on Examples that are
`
`Not Commensurate with the Scope of the Claims
`
`Any claim of criticality must be commensurate in scope with the claims at
`
`issue. In re Clemens, 622 F.2d 1029, 1036 (C.C.P.A. 1980). For a number of
`
`reasons, Infineum’s alleged unexpected results are neither unexpected or
`
`commensurate with the scope of the claims.
`
`First, Infineum’s unexpected results encompass its own comparative
`
`examples. Infineum asserts that its purported invention “provides required
`
`detergency while unexpectedly maintaining sulfated ash production at a reasonable
`
`level without bore polish.” Yet, all of the examples, including comparative
`
`examples, in the ‘274 Patent meet the SASH level of claim 1 and thus the results
`
`cannot be unexpected. Wm. Wrigley Jr. Co. v. Cadbury Adams USA LLC, 683
`
`F.3d 1356, 1362-64 (Fed. Cir. 2012). Further, several of the comparative examples
`
`in Table 1 of the ‘274 Patent report a bore polish value that is below 2 mass%.
`
`Thus, the examples are insufficient to be commensurate with the scope of the ‘274
`
`
`
`-15-
`
`
`
`Case No. IPR2017-01321
`
`Patent. Wyers v. Master Lock Co., 616 F.3d 1231, 1246 (Fed. Cir. 2010).
`
`Second, the alleged unexpected results are not commensurate with the scope
`
`of the claims because the ‘274 Patent does not indicate the calcium detergent in
`
`examples 9-14, which is known to impact bore polish. [Exs.1046, p.163:9-23;1002,
`
`10:19-46]. Even Infineum admits that it was well-known that calcium sulfonate
`
`detergents impact bore polish where the same amount of magnesium detergent is
`
`used. [Ex.1039, p.206].
`
`Since claim 1 recites the calcium detergent as an optional component, one
`
`cannot determine whether the neutral calcium sulfonate detergent impacts bore
`
`polishing. This can be seen in examples 10 and 11 in the ‘274 patent as they both
`
`have the same calcium and magnesium levels, but yield different bore polish
`
`results. [Ex.1046, p.163:24-p.164:22]. Consistent with Infineum’s admissions in
`
`proceedings related to its European patent, this difference is possibly attributable to
`
`the absence of neutral calcium sulfonate. [Ex.1039, p.206]. Thus, the examples of
`
`the ‘274 Patent do not support the alleged unexpected results.
`
`Third, because bore polishing was a known problem with magnesium
`
`detergents and because Colclough and Nicholson disclose conventional treat rates
`
`(including greater than 0.05 wt.% Mg and between 0.06-3.0 wt.% antioxidants),
`
`Infineum has not shown that its arrangement of components yields unexpected
`
`
`
`-16-
`
`
`
`Case No. IPR2017-01321
`
`results.
`
`Finally, magnesium detergents were known to promote oxidation and the
`
`addition of more antioxidant to counteract oxidation does not lead to an
`
`unexpected result. Quite the opposite, it is an expected result.
`
`F. Obvious to Use Magnesium Range in Claim 3
`
`Infineum argues that one would not have been motivated to modify the
`
`amount of magnesium in Nicholson to arrive at the claimed range found in Claim
`
`3. [Response, p.37]. But it is well establish that mere optimization is routine and
`
`requires no inventive skill. In re Peterson, 315 F.3d 1325, 1330 (Fed. Cir. 2003).
`
`Because the ACEA-2004 indicates a minimum target to reduce SASH, there are
`
`market pressures associated with reducing the amount of components that
`
`contribute to SASH. [Ex.2012]. Hence, using less magnesium, which was a known
`
`contributor to SASH, is entirely normal and not at all unconventional. A POSITA
`
`would be motivated to lower the Mg content of Example IV to meet the 1% SASH
`
`limitations provided by ACEA-2004 E6. [Petition, p.41].
`
`More particularly, the precise amount of magnesium would have been
`
`obvious in light of these market pressures. Afton’s expert, Dr. Lam, explains that
`
`the magnesium in Nicholson’s Example IV was known as the component that
`
`provided the most to SASH levels. For example, Dr. Lam calculates that
`
`
`
`-17-
`
`
`
`Case No. IPR2017-01321
`
`Nicholson’s 2.28 wt. % of the detergent would provide approximately 0.197-0.228
`
`wt.% magnesium. [Ex.1004, ¶113]. This corresponds to the measured amount of
`
`magnesium in tests conducted by Mr. Styer. [Ex.1006, ¶56]. Using the E6-04
`
`designation from ACEA-2004, having SASH requirement of less than 1.0 mass%,
`
`a POSITA focused on reducing magnesium in Example IV (the component that
`
`contributes the most to SASH), would have easily been led to reduce the
`
`magnesium detergent so that it provides 0.15 mass% magnesium, which equates to
`
`0.975 mass% SASH. [Petition, p.41].
`
`G. Dispersants in Example IV have 0.8 mass% nitrogen and this
`
`Satisfies Claims 6 and 7
`
`Infineum raises two arguments in an attempt to distance itself from
`
`Nicholson’s disclosure of the claim limitations in Claims 6 and 7. Infineum argues
`
`that Nicholson does not explicitly recite the amount of nitrogen and that
`
`Petitioner’s testing was somehow deficient. But both arguments fail because they
`
`are premised on either an incorrect interpretation of the law, or because they rely
`
`on incorrect calculations.
`
`First, although Nicholson does not explicitly report the amount of nitrogen,
`
`Nicholson without question uses two components that contain nitrogen. And this
`
`fact is not disputed by Infineum. To determine the amount of nitrogen that is
`
`
`
`-18-
`
`
`
`Case No. IPR2017-01321
`
`necessarily part of Nicholson’s Example IV, Petitioner used the most
`
`straightforward way of determining it – through standard measurement.
`
`[Exs.1006, ¶¶55-56;2026, p.89]. Using this measured amount of nitrogen,
`
`Petitioner’s expert, Dr. Lam, performed the routine calculation to determine the
`
`amount of nitrogen in Example IV as 0.08 mass%. [Ex.1004, ¶78].
`
`Infineum’s attack on this clear disclosure rests on convincing the Board that
`
`it should ignore the straightforward, standard measurements performed by a fact
`
`witness, and apply Infineum’s self-servingly restrictive interpretation of the
`
`requirements of 37 C.F.R. §42.65.
`
`Although Section 42.65 does serve as an important standard for evaluating
`
`expert testimony, Monsanto Co. v. Pioneer Hi-Bred Int'l, Inc., IPR2013-00022,
`
`Paper 43:4 (PTAB Apr. 11, 2013), the Board has also made clear that not all data
`
`needs to be disclosed under Section 42.65. 3D-Matrix, Ltd. v. Menicon Co., Ltd.,
`
`IPR2014-00398, Paper 11:9 (PTAB Aug. 1, 2014) (finding that, because peptide
`
`charge computation is pH-dependent and executed via software, it is “the type of
`
`technical data governed by §42.65(b)”). Infineum cites the Board’s decision in
`
`Altaire Pharma, which has been remanded by the Federal C
