“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

“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

“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. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13.

“constructions. 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.

The challenges over Kleve alone or in combination with Sekiyama, Mottla, and/or Patenaude counsel us not to discretionarily deny institution. Patent Owner does not dispute that Kleve, Sekiyama, Mottla, and/or Patenaude were not before the Office. See Prelim. Resp. 15–24; Prelim. Sur-reply 5.

“We agree with Patent Owner that the language in Petitioner’s stipulation does not eliminate completely any overlap with district court invalidity arguments. Petitioner’s stipulation allows Petitioner to use any prior art reference that is not relied on in the Petition. This may not fully address “concerns of inefficiency and the possibility of conflicting decisions.” See Fintiv, Paper 11 at 12. Nonetheless, Petitioner’s stipulation does decrease the overlap in issues and mitigates to a great degree the concerns regarding duplicative efforts and potentially conflicting decisions.

“teaches, or at least suggests, that the user’s “request includes a condition of use of the vehicle as set by the user via the user account” because we are persuaded that the distribution of Kleve’s virtual e-key includes a rental period restriction. Specifically, we are persuaded by the Petition’s reliance on Kleve’s express disclosure that “terms and conditions for the rental period” are agreed to before the virtual key is generated. See Pet. 15 (quoting Ex. 1004 ¶ 38). We preliminarily agree with Petitioner that Kleve describes an e-key that is only operable during a rental period because Kleve discloses “[t]he virtual key may also be sent to the vehicle configuring the VCS to enable the keyless drive system for the appropriate Temporary User during a given rental period.” Ex. 1004 ¶ 39; see Pet. 16. We note Patent Owner’s citations to Kleve’s Figures 2 and 5 that indicate control restrictions are added after the distribution of a virtual key. At this stage of the proceeding, however, based on the disclosure of Kleve we are persuaded the rental period would be included as a restriction when the virtual key is created at step 206 of Figure 2 prior to the distribution of the virtual key at 210. See Ex. 1004 ¶¶ 38–39. At this stage, we credit the testimony of Dr. Almeroth, who opines that Kleve discloses that certain restrictions are sent with the request to generate a virtual key. Ex. 1003 ¶¶ 118–123. Specifically, Dr. Almeroth testifies that Kleve discloses that the virtual key “enable[s] the keyless drive system for the appropriate Temporary User during a given rental period.” restrictions were sent with the request so that the virtual key could be associated with said restrictions.” Id. (citing Ex. 1004 ¶¶ 39, 68 (“Once the rental period has expired the virtual key may be reset and cleared from the VCS.”)). Dr. Almeroth further testifies that the virtual key in Kleve is always generated after the rental agreement. Id.

“(step 406) discloses the claimed “second request” (Pet. 44–45),9 but Petitioner fails to show that this message discloses a request. See Prelim. Resp. 46–48. Han explains that the dual connection setup response in step 406 is a “dual connection setup request acknowledge (ACK)” message sent in response to “dual connection setup request” received in step 404. Ex. 1007 ¶¶ 40–42; accord Pet. 42–44. An acknowledgement is not a request, and Petitioner fails to sufficiently support its contention to the contrary (see Pet. 44–45). According to Petitioner, the acknowledgement message is “a request to change a data path” because the data path is “change[d] . . . based on this message” (id. at 45 (citing Ex. 1007 ¶¶ 42–47; Ex. 1003 ¶ 202)); however, this is faulty reasoning. At most, Petitioner’s argument shows that the acknowledgement is a message “to change a data 9 We note that this is the same message relied upon by Petitioner to teach the claimed “accept message” recited earlier in claim 1. Compare Pet. 44– 45, with id. at 43–44. We need not (and do not) decide whether Petitioner has sufficiently shown that this message discloses two separate claim elements. path,” not that it is a request to do so. In other words, even if Han’s acknowledgement message (in step 406) is a condition precedent to changing the data path, this does not make the message a “request.” Although Dr. Mahon agrees with Petitioner, his analysis mirrors Petitioner’s arguments and suffers from the same deficiencies. See Ex. 1003 ¶¶ 202– 203; see also Motorola, Inc. v. Interdigital Tech. Corp., 121 F.3d 1461, 1473 (Fed.

“U.S.C. § 314(a) due to the advanced state of the parallel district court action, and, in doing so, relies heavily on the district court’s scheduled trial date of September 22, 2025. See Prelim. Resp. 51, 54. While the district court’s scheduled trial date may be earlier than the Board’s projected deadline for a final written decision here, CamelBak’s reliance on that date is misplaced. The Office takes the position that a district court’s scheduled trial dates are “unreliable and often change” and that a more reliable indicator is the district court’s “median time-to-trial for civil actions,” which, in this case, would place the district court’s trial date after the projected deadline of any final written decision here. See Director Memorandum, Interim Procedure for Discretionary Denials in AIA-Post Grant Proceedings With Parallel District Court Litigation, U.S. PATENT AND TRADEMARK OFFICE (June 21, 2022) (“Director’s Interim Procedure”), at 8–9. Thus, CamelBak’s reliance 5 US D586,184 S, issued Feb. 10, 2009 (Ex. 1006, “Miller”). on the district court’s scheduled trial date has no bearing on whether we should discretionarily deny institution. Of greater relevance is Trove’s express stipulation not to pursue the same grounds in the district court action as advanced in the petition or any ground that relies on the prior art references cited in the petition. See Pet. 100. Although not exactly a Sotera stipulation, the Office nonetheless recognizes that such stipulations further mitigate concerns of potentially conflicting decisions and duplicative efforts between us and the district court. See Director’s Interim Procedure, at 7–8. Thus, given Trove’s stipulation and the fact that the district court’s median time-to-trial is after the projected deadline of our final written decision here, we will not discretionarily deny institution under § 314(a).” slip op. at 6

“We disagree that Samartgis is the substantially the same as the corresponding design patent cited during prosecution, mainly because the design patent fails to show the closure retention mechanism that is clearly shown and described in Samartgis and goes to the very heart of Trove’s showing of anticipation and obviousness. Compare Ex. 1004, Figs. 3–5 (showing lug members 15, 16 and ramp sections 23, 25, 27), with Ex. 2001, Figs. 1–8 (omitting any depiction of lug members or ramp sections). Thus, Samartgis clearly was not considered. And, although Leoncavallo and Miller may arguably have been considered during prosecution, “[w]hen instituting . . . review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 42 C.F.R. § 42.108(a).

“Trove proposes that one of ordinary skill in the art would have had: an undergraduate degree in mechanical engineering or equivalent coursework, and a year or more of experience in designing, prototyping, and/or manufacturing fluid containers or similar products . . . [and that] [m]ore work experience may substitute for a lower level of education, and vice versa. Pet. 17–18 (citing Ex. 1003 ¶¶ 25–30). CamelBak appears to agree. See Prelim. Resp. 16 (“Patent Owner assumes Petitioner has correctly stated the level of ordinary skill in the art and does not set forth its own definition.”). At this stage, we see no reason to depart from Trove’s proposed definition, as it appears reasonable and consistent with the asserted prior art and the ’252 patent.” slip op. at 8

“At this stage, we do not see the need to resolve the § 112(f) issue in light of Trove’s express and unrebutted showing that the prior art teaches sufficiently analogous structure to that identified in the ’252 patent for performing the disputed functional limitations of the claimed “closure retention mechanism.” See Pet. 35 (asserting that “[Samartgis’s] lug members 15 and 16 also are at least equivalent to the structure identified in the specification (i.e., the two or more spaced-apart tabs on the handle)” because “[l]ike the opposed tabs of the ’252 patent, the lug members 15 and 16 are projections that extend from the inner surface of the handle to engage the closure.”). Indeed, at this stage, CamelBak chooses not to address Trove’s showing in this regard, instead arguing that “the construction of ‘closure retention mechanism’ is irrelevant because [Trove] fails to show lug members 15 and 16 are configured to meet other limitations of claims 5 and 19.” Prelim.

In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). They are: “(1) whether the art is from the same field of [the inventor’s] endeavor” and “(2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” Id.; see also In re Klein, 647 F.3d at 1348.” slip op. at 33

“II. TIMELINESS OF THE PETITION UNDER 35 U.S.C. § 315(B) Pursuant to 35 U.S.C. § 315(b), “[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 10– 30. However, 35 U.S.C. § 315(b) also provides that the one-year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b). Because the Petition is accompanied by a timely request for joinder (Paper 2) to the instituted proceeding (IPR2024-00017), which we grant as further discussed below, Patent Owner’s argument that the Petition is time-barred under 35 U.S.C. § 315(b) is moot, irrespective of whether Petitioner is in privity with time-barred entities.” slip op. at 5

A motion for joinder should (1) set forth reasons why joinder is appropriate; (2) identify any new grounds of unpatentability asserted in the petition; (3) explain what impact (if any) joinder would have on the trial schedule for the existing review; and (4) address specifically how briefing and discovery may be simplified.

As the moving party, Petitioner bears the burden of proving that it is entitled to the requested relief. 37 C.F.R. § 42.20(c).

“5. “Aid the Movement of Minority Carriers” Patent Owner argues that the Petition fails to show that the applied prior art references disclose the claim limitations “requiring ‘aid the movement of minority carriers,’” as twice recited in claim 1. Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely.
