      “We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices. Tr. 38:3–39:1 (counsel agreeing that one would need to access the area behind splice tray 230 in Holmberg, albeit in “rare occasions”); Ex. 1003 ¶¶ 90–92; Ex. 1033 ¶¶ 7–8. Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray. Pet. 41 (citing Ex. 1005 ¶ 39 (disclosing that a rotatable splice tray or shelf would “provide[] full and convenient access to the splice tray”)). First, Petitioner and Dr. Kiaei persuasively demonstrate that once the fibers of Holmberg are routed from behind splice tray 230 and the distribution cables spooled on this tray, a technician could not reasonably access fiber optic cables stored behind splice tray 230 without releasing or opening splice tray 230. Pet. Reply 14–15 (citing Ex. 1023, 60:20–61:15); Ex. 1033 ¶¶ 31–32. Second, Petitioner persuasively demonstrates that without a hinged connection, the technician would have to either hold the splice tray of Holmberg with one hand while performing the necessary routing and splicing steps, two screws would need to remain in place (essentially replicating a hinge), or the tray would have to be left to dangle, supported only by the routed and spliced fibers.

      “Allegedly New Arguments on Reply Patent Owner contends that Petitioner’s arguments regarding the benefits of a hinged connection when performing the splicing and routing steps should be dismissed or ignored because they were improperly raised for the first time on reply. Sur-reply 19–20. We disagree. The Petition asserts that one of ordinary skill in the art would have sought to add a hinged connection, such as that disclosed in Battey, in Holmberg and would have seen a benefit to so doing. Pet. 40–44. Petitioner did not change its proposed combination or its stated rationale in its Reply. Rather, in response to Patent Owner’s counter-arguments, Petitioner expands upon the benefits of its proposed combination, i.e., the substitution of a hinged connection in place of fasteners. Pet.

      “Patent Owner’s arguments do not persuasively undermine Petitioner’s position. Sakamoto expressly discloses setting the ratio of negative to positive electrode active material in the range of 1.05 to 1.30. Ex. 1005 ¶ 8. Sakamoto also explains why this range is preferable, i.e., if the ratio is roughly equal “the charge-discharge cycle performance is insufficient due to significant deterioration from charging and discharging,” and if the ratio is 10 Citations to the prosecution history of Yamaki are to the page numbers added to the lower right corner of the document. too high “too much of the compound does not participate in charging and discharging.” Id. ¶¶ 6, 8. These disclosures are sufficient to explain why one of ordinary skill in the art would have found it obvious to select the ratios disclosed in Sakamoto in Yamaki. Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Rather, Sakamoto warns against setting the reversible capacities of the positive and negative electrode substantially equal as this may result in excess lithium plating on the surface of the electrode. Ex. 1005 ¶¶ 6, 8. We agree with Petitioner that this disclosure would lead one of ordinary skill in the art to design a battery with a higher capacity in the negative electrode active material than the positive electrode active material.

Thus, a significant portion of the resources consumed in preparing for trial would likely be useful in this proceeding. On November 11, 2024, Petitioner offered a stipulation, stating that, upon institution of this proceeding, Petitioner “will not pursue as to the challenged claims any ground raised or that reasonably could have been raised during the IPR” in the parallel litigation. See Ex. 1043 (filed in this proceeding Nov. 27, 2024). Petitioner’s stipulation applies to the following proceedings, which includes this proceeding: IPR2024-01205, challenging claims 1–20 of U.S. Patent No. 7,593,034; IPR2024-01206, challenging claims 1–13 of U.S. Patent No. 9,485,471; IPR2024-01207, challenging claims 1–22 of U.S. Patent No. 9,912,914. As all the claims of the ’471 patent are challenged in this proceeding, Petitioner’s stipulation applies to the entirety of the ’471 patent. In view of Petitioner’s stipulation, the substantial number of issues to be addressed in the District Court, Patent Owner’s acknowledgement that Petitioner’s expert report in the parallel litigation repeats the assertions in this Petition, and the potential reduction of issues to be tried in the parallel litigation, our weighing of the factors is against exercising discretion to deny institution.

      “At this stage of the proceeding, we are persuaded that Petitioner has established a reasonable likelihood that a person of ordinary skill would have combined the teachings of Yerazunis and Fiore for the reasons arguments do not directly address the specific combination proposed by Petitioner nor the specific motivations provided by Petitioner. For example, as explained further below in our analysis of claim 1, the gun embodiment of Yerazunis does not stop recording video after a triggering event. See Ex. 1017, 17:50–59. Moreover, Fiore’s file-based approach would provide the benefits highlighted by Petitioner regardless of whether Yerazunis stops recording video after a triggering event or continues recording to the next event. Similarly, the argument that Fiore does not selectively write protect data does not address Petitioner’s combination, which relies on Yerazunis, not Fiore, for teaching selectively write protecting data. Patent Owner’s argument also does not explain why a person of ordinary skill would not use Fiore’s file-based approach in implementing Yerazunis’s video recording device. Finally, Patent Owner’s argument that Fiore does not store individual segments within the circular buffer does not address Petitioner’s reliance on Yerazunis’s gun implementation in which individual segments are stored in the circular buffer. See Pet. 28 (“Yerazunis does disclose that in a gun camera embodiment, ‘the head pointer 104 and the tail pointer 102 . . . defining the area(s) of the circular buffer memory, are stored in a table to allow later retrieval of the video data pertaining to each firing of the gun.’” (quoting Ex. 1017, 17:50–56)); see also Pet. 30–32, 38–39.” slip op. at 22

      “of Yerazunis in combination with Fiore. On this record, Petitioner has demonstrated the similarities in the data recording systems of Yerazunis and Fiore. Petitioner asserts a reasonably sufficient basis for establishing the “specified frame data associated with [the] firing event” to be preserved as the disclosure of a designated segment that is write-protected. Based on the current record, we find Petitioner’s evidence more persuasive than Patent Owner’s assertion that Yerazunis preserves the entire buffer—not designated segments. Again, Petitioner admits Yerazunis does not expressly refer to “indexing write-protected segments as second files” but further establishes with sufficient basis that a person of ordinary skill in the art would understand the tagging features of Yerazunis aligns with the concept of indexing. Further, Petitioner shows that eventually it will be necessitated to locate or retrieve the data, providing further motivation for indexing, which is not only disclosed in Fiore, but demonstrated as well known in the art. See Pet. 28–29. Petitioner demonstrates the combination of Fiore and thus, on the current record, we are not persuaded by Patent Owner’s argument that Yerazunis only preserves post-recording data. Patent Owner further does not provide sufficient basis of reasoning that the “memory designation scheme” of Yerazunis which uses “unused block[s] of memory” establishes there is no write-protected segment. In consideration of the above, we are persuaded for purposes of this Decision that Petitioner has cited sufficient evidence to demonstrate that person of ordinary skill in the art would have had a rational basis to combine the teachings of Yerazunis and Fiore and this combination teaches these limitations of element 4.” slip op. at 33

      “At this stage of the proceeding, we are persuaded that Petitioner has established a reasonable likelihood that a person of ordinary skill would have combined the teachings of Yerazunis and Fiore for the reasons provided by Petitioner and summarized above. Several of Patent Owner’s arguments do not directly address the specific combination proposed by Petitioner nor the specific motivation provided by Petitioner. For example, Yerazunis does not stop recording video after a triggering event. See Ex. 1017, 17:50–59. Moreover, Fiore’s file-based approach would provide the benefits highlighted by Petitioner regardless of whether Yerazunis stops recording video after a triggering event or continues recording to the next event. Similarly, the argument that Fiore does not selectively write protect data does not address Petitioner’s combination, which relies on Yerazunis, not Fiore, for teaching selectively write protecting data. Patent Owner’s argument also does not explain why a person of ordinary skill would not use Fiore’s file-based approach in implementing Yerazunis’ video recording device. Finally, Patent Owner’s argument that Fiore does not store individual segments within the circular buffer does not address Petitioner’s reliance on Yerazunis’ gun implementation in which individual segments are stored in the circular buffer.

      “art would not have modified Kurita in view of Lemoff because Lemoff positions the signal emitters near the fiber to emulate WDM without the need for an external optical multiplexer or a similar device and discourages using optical wavelength multiplexers for short distances because the complexity of the design is often cost prohibitive (PO Resp. 47–48), Lemoff does not appear to limit the usefulness of the fiber connector to any particular optical signal transmission distance. Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.... Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art” (In re Keller, 642 F.2d 413, 425 (CCPA 1981)).

Regarding Patent Owner’s argument that the light from each of Kurita’s lasers (11) depicted in Figure 3 cannot pass through a separate focusing lens (30) pie shaped sector because the lasers (11) and collimating lenses (21) are arranged linearly rather than being arranged about a circular axis (PO Resp. at 37–42), we do not agree. Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38). Kurita meets those claim requirements. Kurita’s two by two array (10A) of lasers (11), collimating lens (21) array (20), and focusing lens (30) are shown in Kurita’s Figure 3 (cropped) as follows: The image is a portion of Kurita’s Figure 3 showing Kurita’s laser array, collimating lens array, and focusing lens (30).

      “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.
