“As set forth in the Director’s Memorandum, Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (dated June 21, 2022), at 7, available at https://www.uspto.gov/sites/default/files/documents/interim_proc_discretion ary_denials_aia_parallel_district_court_litigation_memo_20220621_.pdf, the PTAB will not discretionarily deny institution of an IPR . . . in view of parallel district court litigation where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition. Petitioner’s stipulation (Ex. 1025) satisfies the language from the Director’s Memorandum quoted above. Therefore, we need not analyze each Fintiv factor to reach the determination that we will not exercise our discretion to deny institution in view of the parallel Western District of Texas Litigation.” slip op. at 14

“We disagree. The Petition is clear that it presents alternative challenges where Goldberg, Thacker, ITU-T J.83, and/or AAPA are added to the combination of Gibson and Schiltz or are added to Crols, if the term “cable modem,” recited in the preamble of claim 1, is determined to be limiting. Pet. 6–7. In the context presented here, “and/or” clearly means one or more of the four additional references. And Petitioner’s reliance on one or more of the additional references is clear in the context of the issues before us based on Petitioner’s analysis of the preamble of claim 1, where Petitioner clearly states, “[a]nd to the extent that the preamble is limiting and requires a ‘cable modem,’ it would have been obvious to use the modem of Gibson (as modified by Schiltz, discussed below) as a cable modem, in view of Thacker, Goldberg, ITU-T J.83, and/or AAPA.” Pet. 42 (Ground 1); see id. at 66–67 (similarly asserting, in the context of Ground 2, that, “[t]o the extent that the preamble is limiting and requires a ‘cable modem,’ it would have been obvious to use the modem of Crols as a cable modem, in view of Thacker, Goldberg, ITU-T J.83, and/or AAPA”). Petitioner also includes a discussion as to why one of ordinary skill in the art would have been motivated to “use the modems of Gibson modified with Schiltz (Ground 1), and Crols (Ground 2), as ‘cable modems,’ in view of the DOCSIS References (Thacker and Goldberg), ITU-T J.83, and AAPA,” and would have had a reasonable expectation of success in so doing. Id. at 37–40. Thus, we do not agree with Patent Owner that the Petition lacks particularity and we find that the Petition clearly sets forth the alternative combinations discussed above such that Patent Owner has a fair opportunity to respond.” slip op. at 7

“Thus, the evidence shows that: (1) Petitioner and Menard are parties to an agreement; (2) under the agreement, Petitioner supplies accused products to Menard; (3) the agreement includes an indemnity provision; (4) under the agreement, Menard made multiple demands for Petitioner to “indemnify or defend as a matter of first defense”; and (5) Petitioner responded to Menard’s multiple demands by, among other things, filing the Petition challenging the claims in the ’336 patent.

That Petitioner responded to Menard’s multiple demands for Petitioner to “indemnify or defend as a matter of first defense” by filing the Petition shows that the Petition was filed at Menard’s “behest.” Specifically, Menard demanded defense from infringement liability, and Petitioner responded by initiating this proceeding seeking to free Menard from infringement liability for all 20 claims in the ’336 patent.

“As we understand it, one theory of obviousness advanced by Petitioner is combining Fugitt’s teaching that “[t]he rolls of the calender may be steam heated” with Papermaking’s teaching about the surface temperature that can be obtained when using steam to heat the rolls. Pet. 32–33; temperature of Fugitt’s steam-heated rollers in order to achieve a contact surface temperature of at least 250°F, as recited in claim 1. Instead, we understand Petitioner to be relying on Papermaking to teach the temperature of the unmodified rollers of Fugitt. Under this theory, it was not necessary for Petitioner to show that the paperboard substrate properties disclosed in Fugitt would still be achieved after increasing the temperature. Nevertheless, the Petition also relies on Papermaking’s teaching of temperatures that exceed the upper limit for steam-heated rolls, e.g., “[h]igh thermo roll temperatures (in some cases over 200°C [392°F]” or oil-heated rollers having surface that “can reach over 220°C [428°F].” Pet. 33 (citing Ex. 1005, 82; Ex. 1010, 98).

Pet. 35–36; Prelim. Resp. 44. There is a factual issue as to whether a person of ordinary skill in the art would have expected to achieve the paperboard properties disclosed in Fugitt and recited in claim 1, if the roller temperature were increased above the level achievable by steamheated rolls. There is also a factual issue as to whether Patent Owner’s evidence of increased energy cost would outweigh Petitioner’s asserted benefits of increased temperature. These issues are best resolved after the parties have had to the opportunity to develop the record and cross-examine the opposing experts. See Arctic Cat Inc. v. Polaris Indus., Inc., 795 F. App’x 827, 833 (Fed. Cir. 2019) (“The Board must weigh the benefits and drawbacks of the modification against each other, to determine whether there would be a motivation to combine.”).” slip op. at 25

“Given this, to show that Blangero’s disclosure of MgO or LiF in its coating teaches or suggests a rock-salt crystal structure, Petitioner needs to explain why a person of ordinary skill in the art either would have understood the compounds to have a rock-salt crystal structure when manufactured according to the disclosure of Blangero or would have chosen to use MgO or LiF in a rock-salt crystal structure rather than in another available form. On the first point, Petitioner argues that “‘the stable phase at room temperature and pressure conditions’ of MgO is ‘a rocksalt cubic structure of NaCl (space group Fm-3m).’” Pet. 28 (quoting Ex. 1030, 16; citing Ex. 1003 ¶ 142). But, as Petitioner’s declarant, Dr. Hayes, points out, Blangero does not teach forming MgO in a room-temperature process. Ex. 1003 ¶ 142 (Blangero’s “second firing step” occurs at “925 °C for 12 hours”); see Ex. 1005 ¶ 110 (teaching the firing step to which Dr. Hayes refers). Thus, the significance of rock-salt-type MgO being “the stable phase at room temperature and pressure conditions” is unclear. To the extent that Dr. Hayes explains why MgO, which “is well known to crystallize even at substantially lower temperatures,” such as “room temperature and pressure conditions,” would “do so more readily at [a higher temperature of] 925 °C,” this argument is not discussed, nor even cited, in the Petition. Ex. 1003 ¶¶ 90–94; see Pet. 28. Accordingly, any reliance on this argument by Petitioner constitutes improper incorporation by reference. 37 C.F.R. § 42.6(a)(3). Thus, Petitioner does not show sufficiently that a person of ordinary skill in the art either would have understood MgO to have a rock-salt crystal structure when manufactured according to the disclosure of Blangero or would have chosen to use MgO in a rock-salt crystal structure rather than in another available form. Similarly, with respect to LiF, neither Petitioner nor Dr. Hayes sufficiently explains the choice of rock-salt-type material over other options. Pet. 29 (arguing only that Ex. 1013 shows that “LiF has rock salt structure”); Ex. 1003 ¶ 143 (same). Thus, Petitioner does not show sufficiently that Blangero teaches or suggests a rock-salt crystal structure by virtue of its teaching that either MgO or LiF is present.” slip op. at 12

“The 2012 study on which Petitioner relies did not find “superior structural stability” over other lithium-titanium-oxygen compounds, as Petitioner argues. Instead, the study noted that the structure of “LiTiO2 prepared by high-temperature sintering TiO2 with lithium salt . . . impl[ies] LiTiO2 has superior structural stability in organic electrolyte as compared to other Li-Ti-O oxides.” Ex. 1029, 1. Thus, the structural stability was implied from the chemical structure of the material rather than found through study of the material. Moreover, the implied structural stability was only for LiTiO2 that was prepared in a particular way, by high-temperature sintering of TiO2 with lithium salt, and Petitioner does not allege that a person of ordinary skill in the art would have prepared the LiTiO2 they substituted for Blangero’s Li2TiO3 using this method. As for Petitioner’s argument that the study found that LiTiO2 outperformed Li2TiO3, we are not persuaded. The study compared particles with an LiTiO2 coating to uncoated particles, not to particles coated with Li2TiO3. Ex. 1029, 4, Figs. 4(c), 4(d). Although the study notes that particles coated with “[m]onoclinic Li2TiO3 and spinel Li4Ti5O12” exhibit “a noticeable capacity decay . . . when charged at high operating voltage and cycled above room temperature,” it concludes only that particles coated with LiTiO2 “exhibited inspiring high-voltage cycling capability as well as thermal stability than the pristine counterpart.” Id. at 1, 4. In addition, the pristine particles used in the study were made from “Li[NixCoyMnz]O2 (0≤x,y,z<1) (called as LNCM),” and the particles in Blangero do not contain either nickel or manganese in their cores. Ex. 1005 ¶¶ 9–40 (particles contain lithium, oxygen, cobalt, and metals chosen from the group consisting of aluminum, gallium, boron, magnesium, titanium, iron, copper, calcium, barium, yttrium, tin, antimony, sodium, zinc, zirconium, silicon); Ex. 1029, 1. Petitioner does not explain why a person of ordinary skill in the art would expect the study’s results to extend to Blangero’s particles made from a different material. Pet. 29–30. Because Petitioner has not shown sufficiently that Blangero teaches or suggests a second region comprising a rock-salt crystal structure or that a person of ordinary skill in the art would have had a reason to substitute rocksalt-type LiTiO2 for the materials disclosed in Blangero, Petitioner has not shown a reasonable likelihood that it would prevail on claim 1 on its Blangero-based grounds.” slip op. at 15
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner, “[i]ndividuals with different education and additional experience could still [have been] of ordinary skill in the art if that additional experience compensate[d] for a deficit in their education and experience.” Id. On the present record, Patent Owner does not contest Petitioner’s definition of a person of ordinary skill in the art. Prelim. Resp. 19. In light of the record before us, and for purposes of this Decision, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art. Based on our review of the ’660 patent and the prior art of record, we determine that the definition offered by Petitioner comports with the qualifications a person would have needed to understand and implement the teachings of the ’660 patent and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)).” slip op. at 8
