    “Both parties rely on expert testimony for their respective positions relating to the number of years of experience needed to attain ordinary skill, but neither expert cites supporting evidence for their testimony. See Ex. 1002 ¶ 33; Ex. 2002 ¶ 15. Our decision is the same regardless of whether the length of experience is two years or three. We find Patent Owner’s proposed “wireless communications” is more consistent with the ’958 patent than Petitioner’s proposed “telecommunication,” which encompasses a variety of technologies including, e.g., landline and wireless telephones, cable, and satellite. See Ex. 1001, 1:11–62 (describing the invention in terms of wireless communications). Accordingly, we adopt a modified version of Petitioner’s proffered level of ordinary skill in the art, substituting “wireless communications” for “telecommunication.” Neither party, moreover, indicates the overall result would change based on a different definition.” slip op. at 18

    “We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

    “(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag. See supra III.B.4 and IV.B. Further, we are not persuaded that Lee’s transmitting by broadcast is” slip op. at 26

    “Alternatively, even if we set aside that timing issue, Dr. Liu’s bare opinion, advanced for the first time during cross-examination, that an epitaxial layer is “obvious” from Hirler’s disclosure is inadequate to support the challenges. Id. at 24–25. We accord little weight to Dr. Liu’s opinion because it is conclusory. See Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In any event, Petitioner does not meet, on this record, the “high standard” required to establish an inherent disclosure of an epitaxial layer in Hirler.

    “2. Conclusion as to Obviousness For the reasons above, we determine that evidence independent of inventor testimony corroborates (1) a conception date no later than October 22, 2000 and (2) reasonably continuous diligence in reducing the claimed invention to practice until January 19, 2001. Having considered the evidence as a whole under a rule-of-reason analysis, we determine that Unified has not shown that the conception date for the claimed invention was on or after October 24, 2000, or that the inventors did not exercise reasonably continuous diligence during the critical period between October 24, 2000 and January 19, 2001. Unified relies on a priority date of October 24, 2000 for Olgaard and a priority date of December 22, 2000 for Acharya. See Pet. 1–2 & n.2; see also Ex. 1005, code (63); Ex. 1007, codes (22), (43). However, the corroborated conception date for claims 27 and 28 antedates the above priority dates for both Olgaard and Acharya. See supra Section III.C.1. Thus, Unified has not shown that either Olgaard or Acharya is prior art under 35 U.S.C. § 102(e) (2006). Unified provides no theory of obviousness that does not depend on either Olgaard or Acharya being prior art. See Pet. 2, 8–80.” slip op. at 20

First, we find credible Mr. Chang’s testimony that Exhibit 2013 and other related drafts, including their filenames and metadata, have not been altered. Ex. 2031 ¶ 1. We regard the metadata as the most reliable indicator of the latest date each draft was completed. Although the filename dates may differ from the metadata dates, these minor differences do not call into question the reliability of the metadata as the last date on which the drafts were modified. Most significantly, the “last modified” date for Exhibit 2013 is October 22, 2000. That the inventors produced at least three other drafts and then filed a provisional application just ten days later on November 1, 2000 further supports a conception date before October 24, 2000.

Moreover, we find that Petitioner’s stated level of ordinary skill in the art is reasonable because it is consistent with the evidence of record, including the asserted prior art.

Although Dimov discloses non-selective recovery and briefly lists a few general techniques that might be used for either mixing or recovery, Dimov does not specifically indicate which of the techniques would be useful for recovery rather than just mixing, and Dimov does not explicitly disclose that any cell recovery would be selective. Nor has Petitioner shown that Dimov inherently discloses selectively recovering any particular cell that has been cultured and monitored, because, as Dr. Gale persuasively testifies, Dimov’s removal techniques could, as far as a person of ordinary skill in the art would have known based on Dimov’s disclosure, be merely for “removing . . . unwanted particles out of the capture chamber/trench.” Ex. 2012 ¶ 64; see also id. ¶ 63 (“Dimov . . . may suggest removing cellular materials (rather than intact cells) after capture . . . .”). In other words, given Dimov’s general focus on performing experiments within the trenches and the lack of any specific disclosure about how or why to remove cells, Petitioner has not met its burden to show that Dimov’s potential cell-removal techniques would have necessarily been based on a response of a specific cell being cultured and monitored in limitation 1D. We also agree with Patent Owner that Dimov does not disclose any specifics about how to carry out a selective cell removal based on one of Dimov’s listed techniques, such as laser tweezers. See PO Resp. 8–9. Nor does Petitioner meet its burden of showing that such a technique would have been within the ordinary skill in the art at the time of the claimed invention. “In order to anticipate, a prior art disclosure must also be enabling, such that one of ordinary skill in the art could practice the invention without undue experimentation.” Novo Nordisk Pharms., Inc. v.

Given the labyrinthine outlet channels leading from Dimov’s chambers to the common waste stream and Dimov’s lack of any disclosure of a way to identify and extract cells in the outlet streams, we credit Dr. Gale’s testimony that there would have been substantial obstacles to recovering any specific cells that had been liberated from a trench in Dimov’s device.

    “We agree with Patent Owner that Metzger’s gaps define fluid passages located between adjacent side support beams 25 (i.e., “internal walls”) and are not formed in any of the side support beams. We are not directed to any written description in Metzger indicating that the gaps are formed in a side support beam.7 Instead, Figures 5 and 6 of Metzger depict the gaps as being defined between four distinct side support beams 25. Furthermore, as Patent Owner points out, Mr. Kuchel appears to agree that there are no passages formed through the side support beams 25 of Figures 5 and 6. Ex. 2003, 107:12–108:9, 108:17–108:21. For these reasons, we determine that Metzger’s gaps are not formed through an internal wall, as required by claim 1. In the Reply, Petitioner asserts that, even if Metzger discloses four discrete, spaced-apart beams or walls, “the gaps or slices between walls are apertures in a structure through which air can pass.” Pet. Reply 15 (emphasis added). This argument is not persuasive because claim 1 recites that the fluid passage is formed through the internal wall (which Petitioner asserts is met by Metzger’s side support beam 25), not just any structure.

According to Petitioner, because Metzger discloses only a single air inlet valve, an ordinarily skilled artisan would have understood that providing openings, or fluid passages, through the side support beam 25, in lieu of or in addition to the gaps between the side support beam 25, would have been a simple solution to adequately inflate the peripheral frame of the mattress defined by the side support beam(s) 25. Id. at 74–75 (citing Ex. 1002 ¶ 200).

    “Petitioner’s argument that Leonhardt’s valve is attached to the central part of the frame of claim 1 fails. Leonhardt’s valve is undeniably attached to its frame because the valve is sutured or glued to stent 26. Claim 1 requires the valve element to be attached to a portion of the frame located along the radial centerline. Ex. 1001, 19:19–20. However, Leonhardt’s frame (stent 26 coupled via connecting bar 29) is a hollow cylinder devoid of structure located along its centerline. Ex. 1017, Figure 1C. Thus, regardless of how Leonhardt’s valve is attached to stent 26 and connecting bar 29, it is not attached to a structure “located along a centerline” as recited in claim 1 and thus claims 18 and 20.

Pet. 36–38 (nowhere addressing that critical point); Reply 13 (devoting four sentences to rebuttal of Patent Owner’s persuasive evidence that one would not have combined the disclosures of Hallaj, Fohr, and Sato in the manner claimed); see Ex. 1033, 15 (Examiner’s observation, in confirming the patentability of the challenged claims during reexamination, that Sato contains “no information as to how Sato’s cells would be implemented in a pack”). We view Petitioner’s unexplained leap from the single battery cell of Sato to the heat-retaining battery module of Hallaj as a classic example of impermissible hindsight reconstruction driven not by any teaching in the prior art, but by the claim requirement of a “plurality” of cells implemented in a battery pack. Pet. 36–38; Reply 13. Patent Owner, by contrast, comes forward with persuasive evidence, which we credit, showing that one of ordinary skill in the art would not have been led to arrange a plurality of Sato’s cells in the heat-retaining battery module of Hallaj because such a modified battery pack would have been unsuitable for use as a replacement for the capacitors in Fohr. Specifically, we credit the testimony of Dr. Blomgren, who cogently explains why a person of ordinary skill in the art would not have been led to the proposed modification. Ex. 2147 ¶¶ 79–85. Dr. Blomgren explains that the proposed modified battery pack “would not have adequate heat dissipation and the Joule heating naturally occurring during operation” of such a pack “would lead to overheating and cell failure” in a power tool application. Resp. 24 (citing Ex. 2147 ¶ 84). That testimony is consistent with the Examiner’s observation, made during reexamination, that “the discharge rates described in Sato are abnormally high” for a power tool cell and “would lead to overheating of the cells.” Ex. 1033, 14. That testimony also is consistent with information provided by Petitioner’s own witness, Dr. Riley, who acknowledged on cross-examination that the battery pack of Fohr, as modified by Sato and Hallaj, would provide “the heat back to the system after a discharge” and, accordingly, would have no “practical applicability” in a power tool application. Resp. 24 (quoting Ex. 2169, 127:13–18, 131:12–24); see Ex. 2169, 127:9–128:2 (Petitioner’s own witness, Dr. Riley, further explaining that Hallaj is concerned with finding “a way of managing heat generation” in a power supply so that “heat can be used, pulled back into the batteries”). We credit Dr. Blomgren’s testimony that the “storing of heat” in Hallaj would have been “antithetical to” Sato’s lithium-based chemistry cells for use as the energy store in Fohr’s hand held power tool. Ex. 2147 ¶ 83. Petitioner’s own witness, Dr. Riley, provides testimony consistent with that view. Resp. 24 (citing Ex. 2169, 12713–18, 131:12–24) (Dr. Riley’s testimony on cross-examination); see Ex. 2147 ¶¶ 81–85 (Dr. Blomgren’s declaration testimony). That view is reinforced by evidence that the discharge rates supported by Hallaj are orders of magnitude lower than what would have been expected for a battery cell meeting the 20 Amp Limitation. Resp. 25; Pet. 38; Ex. 1015, 5:41-44; Ex. 2147 ¶¶ 79–80; see Ex. 1015, 5:41–44 (Hallaj, describing temperature profiles for discharge rates). We are persuaded that the heat-retaining battery module of Hallaj was not designed to handle, in a power tool application, the discharge currents disclosed for Sato’s individual lithium-based battery cell—much less the discharge currents that would be supplied by a plurality of Sato’s cells. Resp. 25 (citing Ex. 2147 ¶¶ 81, 84); see also Ex. 2147 ¶¶ 62–85 (testimony explaining why one of ordinary skill in the art would not have applied a plurality of Sato’s cells in the battery pack configuration of Hallaj to power Fohr’s hand held power tool). We further find that one of ordinary skill in the art would not have been led to replace the capacitors in Fohr’s power tool with Hallaj’s battery module, modified to include a plurality of Sato’s lithium-based cells. Ex. 2147 ¶¶ 62–85. That combination would have presented a serious risk of overheating and, in light of that risk, an ordinary artisan would not have expected the modified battery pack of Hallaj to successfully power Fohr’s hand held power tool.
