      “The mere existence of some relationship between a petitioner and another entity, however, is not sufficient to place that petitioner in privity with that entity. Google LLC v. DDC Technology, LLC, IPR2023-00707, Paper 27 at 37 (PTAB Oct. 25, 2023). Instead, that relationship must be related to an earlier lawsuit and be “sufficiently close that it can be fairly said that the petitioner had a full and fair opportunity to litigate the validity of the patent in that lawsuit” or the evidence must show “the petitioner is simply serving as a proxy to allow another party to litigate the patent validity question that the other party raised in an earlier-filed litigation.” WesternGeco, 889 F.3d at 1319.” slip op. at 10

      “Petitioner asserts that “[a] person of ordinary skill in the art [“POSITA”] would have at least a bachelor’s degree in chemical engineering, mechanical engineering, or a related field of study with at least two years of experience implementing pollution control in power generation plants for natural gas, coal, and/or industrial waste incineration.” Pet. 11 (citing Ex. 1002 ¶¶ 48–51). Patent Owner does not dispute the level of ordinary skill in the art. See generally Prelim Resp. For purposes of this Decision, we adopt Petitioner’s proposed definition of a person of ordinary skill in the art because it is consistent with the skill level reflected in the disclosures of the ’370 patent and prior art.

      “Petitioner “do[es] not, at this time, contend that any term requires construction,” and instead, states that “[a]ll terms have been accorded their plain and ordinary meaning.” Pet. 10 (citing Ex. 1002 ¶¶ 212–215). Patent Owner does not propose any constructions at this time. See generally Prelim. Resp. Claim terms need only be construed to the extent necessary to resolve the controversy. Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011). On this record and for purposes of this Decision, we see no need to construe any claim term expressly.” slip op. at 13

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateDecided for petitioner

      “We are not persuaded by this argument. The Federal Circuit has instructed that [e]ntitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed. It extends only to that which is disclosed. While the meaning of terms, phrases, or diagrams in a disclosure is to be explained or interpreted from the vantage point of one skilled in the art, all the limitations must appear in the specification. The question is not whether a claimed invention is an obvious variant of that which is disclosed in the specification. Rather, a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought. Lockwood, 107 F.3d at 1571–72. Here, what “a POSITA would understand,” without disclosure in the specification, is insufficient to show written-description support. Prelim. Resp. 24. Thus, on this record, and for purposes of institution, Patent Owner has not shown that the Provisional Application provides sufficient support for adding the claimed genus to the coal. 3. Summary In sum, on this record, Patent Owner has not shown that either the Provisional Application or the Pre-2018 Applications provide sufficient written-description support for the challenged claims. As a result, we determine that the ’370 patent cannot claim priority to the Provisional Application. Thus, all asserted prior art qualifies as prior art.” slip op. at 25

    • PTAB / AIA Trials › §315(b) time barNot time barredDecided for petitioner

      “Based on the current record, we determine that the Petition is not time-barred. The ’370 patent was not part of the 2019 Delaware lawsuit that forms the basis of Patent Owner’s time-bar allegations. And, as Petitioner explains, when the ’370 patent was asserted in July 2024, Petitioner filed this request for inter partes review about seven months later, i.e., within the one-year period. Furthermore, Patent Owner does not allege which unnamed entity is in privity with Petitioner or provide any details of the relationship that establishes privity. Nor does Patent Owner direct our attention to record evidence that would support its allegations. Therefore, without more, we determine that the Petition is not time-barred.” slip op. at 11

      “The current record supports that Petitioner’s combination of Vosteen589 with Starns and with Mass-EPA would have been “the mere application of a known technique to a piece of prior art ready for the improvement.” KSR, 550 U.S. at 401. Indeed, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond that person’s skill.” Id. Patent Owner does not allege that the combination was beyond the skill level of a person of ordinary skill in the art at the time of the alleged invention. See generally Prelim. Resp. Thus, Petitioner has provided sufficient reasoning with rational underpinnings to explain why a skilled artisan would have modified the teachings of the applied references. See KSR, 550 U.S. at 418.” slip op. at 21

      “After reviewing the evidence of record, we are persuaded the instant Petition is not time-barred as to the Chem-Mod Purchasers. Generic indemnity agreements are insufficient, without more, to establish privity. 9 Petitioner asserts that the supply agreements between the Chem-Mod Purchasers and Chem-Mod expired in 2021. For the reasons discussed herein, we determine that the language of these agreements does not establish privity. In the event Patent Owner maintains its argument that the Chem-Mod Purchasers are in privity with Chem-Mod, the parties should address the legal impact, if any, of the expiration of these agreements on Patent Owner’s arguments. WesternGeco LLC, 889 F.3d at 1321 (a “contractual and fairly standard customer-manufacturer relationship regarding the accused product” does not suggest, “without more, that the parties were litigating . . . [an] IPR[] as proxies for the other.”). The only relationship alleged to exist between Chem-Mod, its affiliates, and the Chem-Mod Purchasers is that of a supplier-customer relationship. As part of that relationship, the parties entered into supply agreements that included an indemnification provision for the purchased products. Exs. 2037–2042 (discussed at Sur-reply 7–8). We acknowledge, but disagree with, Patent Owner’s argument that the terms of the indemnity “specifically targeted” the activities at the “heart of the alleged infringement.” Sur-reply 7–8. Rather, the indemnification language in these agreements appears to be standard and typical of supply agreements. See Ex. 2037, 26;10 Ex. 2038, 10–12; Ex, 2039, 10–12; Ex. 2040, 10–12; Ex. 2041, 10–12; Ex. 2042, 24–27.

      “Patent Owner does not point to any record evidence that suggests the parties to the Delaware Action adequately represented the Chem-Mod Purchasers’ interests or that the Chem-Mod Purchasers controlled, directed, or funded the Delaware Action. See generally Prelim. Resp.; Sur-reply. Nor does Patent Owner suggest that the indemnified Petitioners are acting as a proxy for Chem-Mod and its affiliates in this case. Thus, the relationship with Chem-Mod, its affiliates, and the indemnified Petitioners was not “sufficiently close that it can be fairly said petitioner had a full and fair opportunity to litigate the validity of the patent in that lawsuit.” Google, IPR2023-00707, Paper 27 at 37. In sum, Petitioner bears the burden of demonstrating compliance with 35 U.S.C. § 312(a)(2) and § 315(b), but the current record does not provide sufficient reason to doubt Petitioner’s assertion that Chem-Mod was not “funding this petition, advising on strategy for this petition, or exercising any control over Petitioner’s decision to file the petition (or the arguments included therein).” Pet. 2; see also Reply 1–2. Indeed, the current record supports that the relationship between Chem-Mod and the Chem-Mod Purchasers was a standard supplier/customer relationship. Exs. 2037–2042. The evidence does not support that Chem- Mod negotiated a license on behalf of the Chem-Mod Purchasers or that the Chem-Mod Purchasers owned power plants that were at issue in the Delaware Litigation. Ex. 2009, 91; Ex. 2010, 107. Therefore, on this record, we determine that the relationship between Chem-Mod and the Chem-Mod Purchasers does not support that the Petition is time-barred.” slip op. at 15

CONCLUSION Based on the current record, and for the reasons explained above, we find Petitioner has demonstrated a reasonable likelihood that it would prevail with respect to at least one claim challenged in the Petition. We, therefore, institute an inter partes review of all challenged claims on all asserted grounds. This Decision is not a final determination on the patentability of any challenged claim. Our view with regard to any conclusion reached in the foregoing could change upon further development of the record during trial. We remind the parties that any argument not raised in a Patent Owner Response to the Petition, or as permitted in another manner during trial, shall be deemed forfeited and/or waived even if asserted in the Preliminary Response.

      “We agree with Petitioner that the skilled artisan would have had reason to combine the teachings of Richardson and Zhao to achieve the subject matter of claim 1. For example, Petitioner contends that a person of ordinary skill in the art would have modified Richardson’s system to include the USB input circuit of Zhao “to avoid the need to supply a proprietary charger or other type of AC ‘power brick’ that would be less ubiquitous or less standardized,” increase flexibility and convenience, and cater to consumer demand for USB technology. Pet. 36 (citing Ex. 1003 ¶¶ 88–89). Petitioner further alleges that the addition of a USB input circuit would provide for an alternative where traditional charging methods are lost, damaged, or otherwise unavailable. Id. at 35 (citing Ex. 1003 ¶ 88). Thus, Petitioner has provided sufficient reasoning with rational underpinnings to explain why a person of ordinary skill in the art would have modified the teachings of the applied references.

      “Ex. 1005 ¶ 28 (emphasis added). Dr. MacCarley testifies that a person of ordinary skill in the art would have known what external battery charger could have been used and where to place it in Richardson’s system. Ex. 1044 ¶ 13. In particular, Dr. MacCarley explains that there are numerous points in the circuitry disclosed by Richardson where a charging pathway from an external battery charger (e.g. the “battery charger” that Richardson explains is “not shown”, EX1005, ¶ [0028]) could be connected to charge Richardson’s batteries. EX2010, 52:3–54:5. Any of these connection points would be a trivial modification of Richardson’s embodiment. A PHOSITA would have understood how to implement this type of well-known configuration of an external battery charger and associated charging circuitry, which would have been as simple as wiring connections to the terminal anode and cathode of the batteries. The simplicity of this connection is why it is not surprising that Richardson describes such a pathway and leaves it “not shown” in the figures. Id. We credit the testimony of Dr. MacCarley in this regard. Moreover, Dr. Fayed confirms that it was known to recharge a jump starter with a barrel charger. Ex. 2014 ¶ 23.” slip op. at 28

Pet 45–46 (citing Ex. 1003 ¶¶ 88– 89). Petitioner further alleges that the addition of a USB input circuit would provide for an alternative where traditional charging methods are lost, damaged. or otherwise unavailable. Id. at 45 (citing Ex. 1003 ¶ 88). Thus, Petitioner has provided sufficient reasoning with rational underpinnings to explain why a person of ordinary skill in the art would have modified the teachings of the applied references. See KSR, 550 U.S. at 418. We acknowledge, but are not convinced by, Patent Owner’s arguments that the nature of Richardson requires the ability to charge a high capacity battery and rapid recharging and therefore would not have led a person of ordinary skill in the art to include Zhao’s USB charging circuit in Richardson. See PO Resp. 25–31. In particular, we are not persuaded that Richardson is limited to high capacity, rapid recharging of batteries as Patent Owner suggests. Instead, Richardson broadly describes “an apparatus and method for temporarily delivering supplemental power to the electrical system of a vehicle” (Ex. 1005 ¶ 6) where “[t]he jump starter 10 may be configured for 12, 18, 24, 30, 36, 42 or 48 volts” (id. ¶ 34). According to Richardson, this may be achieved by using “two or more batteries of the same or different voltage levels . . . to achieve the voltage requirements of the vehicle to be started.” Id. By way of example, Richardson states that “if the batteries 23 are both 12-volt batteries, the system may be configured for 12- or 24-volt operation” and “[i]f the batteries 23 are 12-volt batteries and a battery 25 is a 6-volt battery, 18- or 30-volt configurations may be provided.” Id. Neither Richardson’s claims nor its specification require any particular charging capacity or charging time. See generally Ex. 1005. While a single, near-final paragraph of Richardson introduces the concept of rapid charging of the jump starter batteries to charge a fleet of vehicles, Richardson characterization is permissive or optional. For example, Richardson states The charging system of the vehicle may be used to charge the capacitors 21 and jump starter batteries 22. . . . This allows the capacitors 21 and jump starter batteries 22 to be fully recharged in about 1 to 5 minutes and can therefore start many vehicles in a row without becoming discharged. Id. ¶ 55 (emphasis added). We do not view this singular occurrence as supplanting the breadth of Richardson’s complete disclosure. Furthermore, the crux of Patent Owner’s argument is that because of Richardson’s goal of charging high capacity batteries a USB charger would require significant charging time. PO Resp. 29; Sur-reply 2–14 But, nowhere does Patent Owner allege that a USB charger would not work given sufficient time.11 See generally PO Resp. and Sur-reply. And, when faced with no alternative, the person of ordinary skill in the art must balance the trade-offs and consider charging slowly, or not at all. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (explaining that “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine”); see also Winner 11 Petitioner in its Reply presents some evidence of charging times using a USB input charger. Pet. Reply 4–7; Ex. 1044 ¶¶ 6–12, Appendix A. Patent Owner disputes the accuracy of Petitioner’s calculations. Sur-reply 2–11. But, whether Petitioner’s calculations are accurate or not, Petitioner’s proposed alternative modification does not remove the faster charging path and instead adds the convenience and flexibility of a secondary charging method where the primary and faster charging path is unavailable.
