    Claims 1–22 were not shown unpatentable because Sample C was not proven publicly available as prior art, and the original decision found the remaining grounds insufficient.

    • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication not establishedNot shown unpatentable

      “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012). The Technical Data Sheets may support a finding that the Xirallic® products they describe existed as of the dates on the documents, but they do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.” slip op. at 20

      “witnesses. See Elbit Systems of Am., LLC v. Thales Visionix, Inc., 881 F.3d 1354, 1358 (Fed. Cir. 2018) (citing Trs. of Columbia Univ. v. Illumina, Inc., 620 F. App’x 916, 922 (Fed. Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Not shown unpatentableNot shown unpatentable

      “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

Patent Owner also states that a “second IPR was filed against the same patent in proceeding IPR2024-01490.” Paper 4, 1. Patent Owner does not argue that we should exercise discretion under 35 U.S.C. § 314(a) because Petitioner uses more than one petition to challenge the ’731 patent. challenges the alleged priority date of the ’731 patent (IPR2024-01489) (‘First Petition’) and the second petition assumes that the Patent Owner’s claimed priority date is valid, and addresses prior art references predating that priority date (IPR2024-01490) (‘Second Petition’).” Ex. 1019, 1. In accordance with the Consolidated Trial Practice Guide1 (“CTPG”), issued in November 2019, “there may be circumstances in which more than one petition may be necessary” including “when there is a dispute about priority date requiring arguments under multiple prior art references.” CTPG 59. Such is the case here. Patent Owner does not file any Preliminary Response or other paper disputing Petitioner’s use of two petitions to challenge the claims of the ’731 patent. Based on the record before us, we consider the merits of both petitions because Petitioner’s stated reasons for filing two petitions are consistent with the CTPG. See generally Ex. 1019 (citing CTPG, 59 (“the Board recognizes that there may be circumstances in which more than one petition may be necessary, including, for example, . . . when there is a dispute about priority date requiring arguments under multiple prior art references)).

We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended.

      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged.

First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery.

      “We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id.
