    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)InstitutedInstituted

      “Institution of an inter partes review is authorized by statute when “the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a) (2018). Upon consideration of the Petition, the Preliminary Response, and the evidence of record, we determine that Petitioner has established a reasonable likelihood that it would prevail in showing the unpatentability of at least one claim challenged in the Petition. We also determine that the arguments and evidence of record do not support discretionary denial under 35 U.S.C. § 314(a). Accordingly, we institute an inter partes review of all claims and all grounds asserted in the Petition.1” slip op. at 2

Here, we do not find the first five factors cumulatively weigh in favor of discretionary denial. Therefore, we determine that the circumstances here do not warrant an analysis of whether the Petition presents compelling merits, and the considerations of the sixth Fintiv factor weigh against exercising discretionary denial.

      “Thus, although both parties indicate that no claim construction is necessary at this stage of the proceeding, it is apparent that they disagree as to the meaning of “discrete carbon nanotubes.” While Petitioner appears to construe “discrete carbon nanotubes” as “nanotubes that are generally individually distinct” (Pet. 13), Patent Owner argues a more restricted construction requiring that “discrete carbon nanotubes” not be reacted with other components. Prelim. Resp. 3. The evidence relating to claim 10 In quotations from the Preliminary Response throughout this Decision, we have retained bolding and underlining added to the text by Patent Owner. construction that Patent Owner offers on the current record, however, does not address its proposed restriction. See id. at 9, n. 4, citing Ex. 1001, 3:9, 5:39–40 (“The ’649 Patent describes the ‘discrete carbon nanotubes’ as, for example, ‘individually dispersed’, ‘individualized carbon nanotubes’, ‘dispersed as individual nanotubes’, and ‘essentially discrete individual fibers, not entangled as a mass.’”). As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). If either party intends to argue a claim construction at trial, however, including what is the ordinary meaning of a term, they should do so in a clearly designated section of their briefing. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 21, 2019) (“CTPG”), 46, 49 (available at https://www.uspto.gov/TrialPracticeGuideConsolidated); O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”). Claim construction arguments should not be relegated to patentability arguments on the facts.” slip op. at 7

      “Petitioner argues a person of ordinary skill in the art at the time of the invention “would have had at least [a] Master’s degree in materials science, chemistry, chemical engineering, a field relevant to polymer science and engineering, or the equivalent, and at least three years of experience in nanomaterials, electrochemistry, batteries, or polymer related activities.” Pet. 5 (citing Ex. 1003 ¶ 19). Petitioner further argues that “[a]dditional work experience can compensate for less formal education, and vice versa.” Id. Patent Owner does not dispute the level of ordinary skill in the art. Prelim. Resp. 4. For purposes of this decision, we adopt Petitioner’s definition of the level of ordinary skill in the art because it is consistent with the ’649 patent and the asserted prior art.” slip op. at 9

      “review. See 35 U.S.C. § 314 (2018); 37 C.F.R. § 42.4(a) (2023). The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted “unless the Director determines . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Having considered the arguments and evidence set forth by Petitioner and Patent Owner, we determine that the information presented in the Petition demonstrates a reasonable likelihood that Petitioner would prevail on at least one of the challenged claims of the ’909 patent. We also determine that the arguments and evidence of record do not support discretionary denial of the Petition under 35 U.S.C. § 314(a). Accordingly, we institute an inter partes review as to all of the challenged claims of the ’909 patent on all of the grounds of unpatentability set forth therein.” slip op. at 2

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

      “Contrary to Patent Owner’s arguments, the law on overlapping ranges in obviousness challenges is clear. See In re Peterson, 315 F.3d 1325, 1329 (Fed. Cir. 2003) (“A prima facie case of obviousness typically exists when the ranges of a claimed composition overlap the ranges disclosed in the prior art.”). Here, Petitioner directs us to evidence of an overlapping range, which is not meaningfully disputed by Patent Owner. As to Patent Owner’s arguments regarding the lower end of the claimed range of aspect ratios and Ohata’s warning about aspect ratios below 100, we note that Ohata states that its carbon nanotubes “preferably have an aspect ratio . . . of not less than 100,” and expressly includes examples with an aspect ratio of 50. Ex. 1004 ¶ 20 (emphasis added), Table 2 (Examples 12 and 14). Patent Owner also criticizes Petitioner for relying on oxidizing Ohata’s nanotubes in view of Kavan (discussed in more detail below). Prelim. Resp. 6. According to Patent Owner, oxidation is known to shorten the length of nanotubes, which would impact the aspect ratio of the nanotubes in the proposed combination. Prelim. Resp. 6. Specifically, Patent Owner contends that oxidizing Ohata’s nanotubes will reduce the aspect ratio below 100, and argues that “Petitioner has not explained why a [person of ordinary skill in the art] would ignore Ohata’s warning nor has Petitioner provided evidence that the resulting combination will perform as Petitioner alleges.” Prelim. Resp. 7; see also Prelim. Resp. 8 (arguing Petitioner has not explained why a person of ordinary skill in the art would try to retain Ohata’s aspect ratio and expect success when Ohata is altered in view of Kavan). Even giving Patent Owner’s arguments their full weight, there is no evidence on the present record as to how much the aspect ratio of Ohata’s nanotubes would be reduced as a result of oxidation. Rather, based on the present record, namely, the broad range of aspect ratios disclosed in Ohata (preferably 100–1000), it seems reasonably likely that the aspect ratio of at least some of the oxidized nanotubes in the proposed composition would remain within the range disclosed in Ohata and overlap the claimed range, as Petitioner asserts. Nevertheless, the parties may address during trial the expected level of carbon nanotube shortening in the proposed combination of Ohata and Kavan.” slip op. at 21

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayTeaching away not foundDecided for petitioner

      “To the extent Patent Owner is presenting a teaching away argument, these statements do not rise to the level of criticizing, discrediting, or discouraging investigation into the claimed invention. DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009). Indeed, in addition to its statement regarding oxidation not being necessary for anchoring to TiO2, Kavan also states that oxidation of carbon nanotubes “was sometimes mentioned to improve anchoring of TiO2.” Ex. 1005, 2. Moreover, the full statement from Kavan regarding storage capacity reads: “The Li-storage capacity of TiO2 is not enhanced in the composite, but the rate of electrochemical charge transfer is higher due to nanotube networking.” Ex. 1005, 9. Thus, in its entirety, this statement supports Petitioner’s argument that there are advantages to using oxidized nanotubes, and, in turn, provides a reason why a person of ordinary skill in the art would have used oxidized nanotubes. Moreover, the evidence Petitioner presents regarding the use of oxidized nanotubes in combination with TiO2, coupled with Ohata’s statement that the electrode active material to be used can vary depending on the battery type (Ex. 1004 ¶¶ 26–27), undermines Patent Owner’s criticism that Petitioner’s arguments are circular.” slip op. at 24

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied

      “Although the parties appear to agree that this factor is neutral, we note that a district court denial of a motion to stay without prejudice, accompanied by an indication that the district court would consider a renewed motion, “suggests the district court may be willing to avoid duplicative efforts and await the PTAB’s final resolution of the patentability issues raised in the petition before proceeding with the parallel litigation.” Fintiv at 6–7. “This fact has usually weighed against exercising authority to deny institution.” Id. (also noting that factors 2 and 3 are relevant to how much weight to give to the court’s willingness to reconsider a stay); see also T-Mobile, Paper 16 at 12 (noting that a stay was unlikely in that case given the proximity of the trial date to the entry of the institution decision). In view of the forgoing, we determine that Fintiv factor 1 weighs against exercising our authority to deny institution.” slip op. at 37

      “On this preliminary record, we agree with Petitioner that the intrinsic record does not support a construction of “stackable add-on layer” that encompasses formation of memory cells by sequential deposition on a plain language of the claim does not require merely a “layer” having a plurality of vertically oriented semiconductor memory cells, but rather “a stackable add-on layer” having a plurality of vertically oriented semiconductor memory cells that is bonded to the dielectric layer. Ex. 1001, 12:29–32. The written description of the ’702 patent strongly suggests that such “a stackable add-on layer” is formed separately from the substrate and then stacked on and bonded to the substrate. Id. at 1:47–50 (“Briefly, a plurality of vertically oriented semiconductor memory devices, or cells, may be added to a separately fabricated substrate that includes electrical devices and/or interconnect lines.” (emphasis added)). It is unclear how memory cells sequentially deposited on a substrate could be considered to be a plurality of memory devices “added to a separately fabricated substrate.”” slip op. at 7

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied

      “3. Factor 3 – Investment in the parallel proceeding by the court and the parties Under the third Fintiv factor, we consider the “investment in the parallel proceeding by the court and the parties.” Fintiv, Paper 11 at 6. Petitioner contends that, at the time of the filing of the Petition, the court had not yet held a case management conference or set a Markman or trial date, and that no hearings or substantive activities or hearings have occurred in the case. Pet. 75. “Because the investment in the trial has been minimal and Petitioner acted diligently” in filing the Petition, Petitioner contends “this factor weighs strongly against discretionary denial.” Id. Patent Owner contends the co-pending district court case has been moving forward, with infringement and invalidity contentions being exchanged and discovery and deposition underway. Prelim. Resp. 34. Patent Owner further contends that by the institution deadline of November 28, 2023, the parties will be in the “home stretch of discovery.” Id. at 34– 35. “Based on the considerable resources already expended on contentions and discovery in the district court,” Patent Owner argues that Fintiv factor 3 weighs in favor of denying institution. Id. at 35. directed to no substantive rulings by the district court to suggest that it has invested considerable resources in the case. Nor are we presented with evidence that the parties have expended significant resources in the district court litigation. Fact discovery is not scheduled to be completed until July 1, 2024, and expert discovery is to be completed by August 5, 2024, i.e., more than seven months after the institution deadline. Ex. 2001, 3. Accordingly, we determine that Fintiv factor 3 weighs against discretionary denial of institution. 4. Factor 4 – Overlap between issues raised in the petition and in the parallel proceeding Under the fourth Fintiv factor, we consider the “overlap between issues raised in the petition and in the parallel proceeding.” Fintiv, Paper 11 at 6. Petitioner contends that in the district court litigation Patent Owner asserts infringement under only claim 13, whereas the Petition challenges claims 13–17. Pet. 76. Petitioner argues that because it is challenging more claims than are asserted in the district court litigation, this proceeding “is the only venue in which the invalidity challenges against several claims in the ’702 Patent will be adjudicated,” and this proceeding will promote efficiency because it “will resolve disputes against future district court defendants.” Id. Patent Owner responds that Petitioner’s “invalidity contentions challenge the same Claims 13–16 based on the identical Watanabe, Lee, and Endoh references relied upon in the Petition.” Prelim. Resp. 35. Petitioner responds that it has signed and served a stipulation “not to pursue in the parallel district court proceeding any obviousness ground that includes the primary references in the Petition.” Prelim. Reply 2. According to Petitioner, “[t]his stipulation mitigates concerns of potentially the PTAB.” Id. Patent Owner argues in response that Petitioner’s “meager agreement” slip op. at 30

      “the application describe the claim limitations exactly,” the application must demonstrate to persons of ordinary skill in the art that the applicants invented a composition including those limitations. Wertheim, 541 F.2d at 262. On its face, the range of “at least 0.01 wt. %” encompasses a range that is broader than 0.01–35 wt. %, and Patent Owner does not sufficiently explain why a person of ordinary skill in the art would understand from merely a disclosure of 35 wt.% that the inventors were in possession of the entire claimed range for copper, cobalt, or nickel in the magnesium composition.” slip op. at 11

    • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportPriority date, deniedOther

      “On this record, the term “at least 0.01 wt. %” in the ’740 patent encompasses values for nickel, copper, and cobalt that are higher than the 35 wt. % (nickel and copper) and 20 wt. % (cobalt) limits outlined in the parent and grandparent applications. Accordingly, we determine that there is a reasonable likelihood that claim 19 of the ’740 patent is not entitled to the benefit of the filing dates of its priority applications. Challenged claims 20–61 and 63–75 depend from claim 19 and there is no argument presented that these claims have independent written description support in Doud. For example, there is no evidence presented that any of these dependent claims narrow the ranges for each of copper, nickel, and cobalt recited in in the ’295 application for these claims.7 Accordingly, for purposes of this Decision, we apply Doud as prior art to challenged claims 19–61 and 63–75.” slip op. at 12

Ex. 1005 ¶¶ 45, 47; Ex. 1001, 21:43–51, 22:48–53, 33:32–43, 34:9–12. To this alloy is added either 7 wt. % nickel or 10 wt. % copper.

These additives are mixed in the magnesium alloy at a temperature that is less than the melting point of copper or nickel, and the casting is then cooled.

Doud reports that nickel and copper, when added to molten magnesium, will form Mg2Ni and CuMg2 intermetallic, galvanically-active, in situ precipitates. Ex. 1005 ¶¶ 12–13. Doud discloses that the dissolution rate of the resulting casting material is either 325 mg/cm2-hr (nickel) or 50 mg/cm2-hr (copper) in a 3% KCl solution at 90° C.

      “including Petitioner’s Reply Brief (Paper 10, “Reply Br.”) and Patent Owner’s Sur-Reply Brief (Paper 11, “Sur-Reply Br.”), we agree with Petitioner that Patent Owner’s proposed definition reads into the claim a numeric threshold for solubility from an embodiment that is nowhere apparent from the claim itself. Reply Br. 1–2. “[I]nterpreting what is meant by a word in a claim is not to be confused with adding an extraneous limitation appearing in the specification, which is improper.” In re Cruciferous Sprout Litigation, 301 F.3d 1343, 1348 (Fed. Cir. 2002) (internal quotation marks and citations omitted; emphasis in original). Although courts must read a patent’s claims in light of the specification, see, e.g., Comark Communications, Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998), that obligation does not authorize “reading a limitation from the written description into the claims,” which is characterized as “one of the cardinal sins of patent law,” SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001). Confining the scope of “capable of imparting solubility” to an unexpressed minimum solubility taken from one of the Specification’s embodiments crosses that line.

      “The express language of claim 1 requires no solubility threshold, and dependent claim 10 of related U.S. Patent No. 10,288,620 B2 demonstrates that, where a solubility threshold was intended by the inventors of these patents, they knew how to expressly set forth that threshold in the claims. Compare Ex. 1004, 222:47–49 (“capable of imparting solubility in water”), with Ex. 1005, 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’648 patent explains that “each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Ex. 1004, 2:21–22; Prelim. Resp. 17. This solubility threshold, however, is not in claim 1. Also, the ’648 patent states that this solubility applies only to some embodiments. See, e.g., Ex. 1004, 53:9–12, 55:6–20. We decline to import such a limitation from the written description into claim 1 absent reason for doing so. See SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001) (explaining that “reading a limitation from the written description into the claims” is “one of the cardinal sins of patent law”); see also Thorner v. Sony Comp. Ent’m Am., LLC, 669 F.3d 1362, 1366 (Fed. Cir. 2012) (“It is likewise not enough that the only embodiments, or all of the embodiments, contain a particular limitation. We do not read limitations from the specification into claims; we do not redefine words.”). After considering the parties’ arguments and evidence presented, we agree with Petitioner that Patent Owner’s proposed definition reads into the claim a numeric threshold for solubility from an embodiment that is nowhere apparent from the claim itself. “[I]nterpreting what is meant by a word in a claim is not to be confused with adding an extraneous limitation appearing in the specification, which is improper.” In re Cruciferous Sprout Litigation, 301 F.3d 1343, 1348 (Fed. Cir. 2002) (internal quotation marks and citations omitted; emphasis in original). Although we must read a patent’s claims in light of the specification, see, e.g., Comark Communications, Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998), that obligation does not authorize “reading a limitation from the written description into the claims.” SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001). Confining the scope of “non-ionic side group capable of imparting solubility in water” to an unexpressed minimum solubility taken from only “some” embodiments encompassed by the ’648 patent crosses that line. See, e.g., E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1432–34 (Fed. Cir. 1988) (Claims to a co-polymer improperly interpreted to include two properties).

      “be lifted for each patent for which the petition is denied. As noted above, there are six related petitions at the Board involving the patents before the court. The district court stayed the litigation “pending resolution of the IPR proceedings that have been instituted on the patents at issue in this case.” Ex. 2006, 2. Regarding the length of the stay, the district court explicitly ordered the parties not to use continuance of the fact discovery to October 28, 2022 “as grounds for . . . opposing institution of any post-grant proceeding.” Ex. 2007, 2. Regarding when the stay will be lifted, the order merely gives Patent Owner the opportunity to “seek to lift the stay as to any patents that are not instituted for review.” Ex. 2006, 2 (emphasis added). But we decline to speculate whether the district court would grant such a motion directed only to one of the six patents. Among the reasons warranting a stay of the litigation, the district court found “IPR has the potential to streamline issues for trial” and “the resources the parties will need to expend for experts could be significantly impacted by the outcome of any instituted IPR proceedings.” Id. Thus, the litigation is stayed pending the outcome of the six related proceedings, not merely the outcome of this institution decision, and the district court stayed the litigation for the explicit purpose of gaining efficiency and avoiding duplication of efforts by letting this inter partes review proceed to its conclusion first.14 See Prelim. Reply. 4–5. While Patent Owner may seek to lift the stay as to any patent for which institution is denied, the grant of any such request is uncertain. Accordingly, this factor strongly weighs against discretionary denial of institution.” slip op. at 15
