“6. Whether Choi and Kim Are Printed Publications Pursuant to 35 U.S.C. § 311(b) Multimedia contends that Choi and Kim are not printed publications under 35 U.S.C. § 311(b) because they were not published before the ’040 patent’s priority date of August 17, 2012. PO Resp. 13–14. Multimedia referenced a case pending at the Federal Circuit, Lynk Labs, Inc. v. Samsung Electronics Co., Ltd., as pertinent to addressing whether applications for patent published after the priority date of the challenged patent are permissible “printed publications” in IPRs. Id. Multimedia’s arguments are not persuasive because on January 14, 2025, the Federal Circuit in Lynk Labs Inc. v. Samsung Electronics Co.

Relying on the testimony of Dr. Lippman, LG argues the following: [a] Person of Ordinary Skill in The Art . . . in August of 2012 would have been someone knowledgeable and familiar with the interactive media guide arts that are pertinent to the ’040 patent. A [person of ordinary skill in the art] would have had a bachelor’s degree in Electrical Engineering, Software Engineering, or Computer Engineering, or equivalent training, and approximately two years of experience working in the field of television systems and networking, human-computer interaction, or related technologies.

“highlighted when a user selects this content source in some manner. Ex. 1001, 30:27–51. At that juncture, after a user selects the content source and it is highlighted, the content source is then associated with the first content information, “801 – CNXN,” which is displayed on the right panel of Figure 15B. See id. We do not understand the ’040 patent as requiring the display “801 – CNXN” to cause the corresponding highlighting of Live TV 1504A as suggested by Multimedia. The claim language requires the two elements “being associated with”5 one another, but it does not require that one element’s display (first content information) causes the highlighting of the other element (content source). Our view is supported by the only description of highlighting a content source found in the specification of the ’040 patent. In regard to Figure 15B, the specification describes that “global panel 1404 may include one or more sources represented by icons and text, or shortcuts, 1504A-E.” Ex. 1001, 30:27–28. The specification describes how highlighting the source is user directed: Global panel 1404 may additionally indicate a source that is selected or highlight [sic] using indicator 1512; for example, indicator 1512 may comprise a box positioned around Live TV 5 As the Federal Circuit has explained, “the plain meaning of associating relates to a mere commonality.” Apple Inc. v. Motorola, Inc., 757 F.3d 1286, 1306 (Fed. Cir. 2014), overruled by Williamson v. Citrix Online, LLC, 792 F.3d 1339 (Fed. Cir. 2015) (on unrelated grounds). 801 CNXN. Although illustrated as a box, other methods or configurations which provide for icon selection and/or identification may be used. For example, instead of a box, indicator 1512 may comprise adjusting the background of an icon and text, such as 1504A for example, such that the color, shade, or hue is different. Id. at 30:41–49 (emphasis added). Highlighting, as the specification describes, occurs when a user selects a source using indicator 1512 and that source is boxed or differentiated by color or shading. Id. The specification, in relation to Figure 15C, further describes a user moving indicator 1512 to another source such that the “the content or a preview of the content may be displayed in active content area 1408.” Id. at 32:9–17 (“For example, FIG. 15C illustrates an image or video associated with Skyfalls being displayed in content area 1408.”). Thus, the specification is clear that the highlighting function results from user selection of the source and the corresponding association of the first content information with that source flows from that user selection. See also id. at 2:30–31 (describing a purpose of the ’040 patent as “an Intelligent TV with intuitive user interfaces and with seamless user interaction capability”), 32:35–43 (“[t]he user . . . move[s] the focus box”).

“Based on the arguments and evidence, we disagree with Petitioner’s proposed construction requiring the corners to be rounded via a particular process, because doing so would improperly import a process of manufacture from the Specification into apparatus claims. See Cont’l Circuits LLC v. Intel Corp., 915 F.3d 788, 799 (Fed. Cir. 2019) (explaining that, generally, a novel product that meets the criteria of patentability is not limited to the process by which it was made, however, process steps can be treated as part of a product claim if the patentee has made clear that the process steps are an essential part of the claimed invention). Here, the portions of the Specification relied on by Petitioner (Ex. 1001, 2:10–20, 4:53–64) disclose a process for manufacturing but do not make clear that the process is an essential part of the claimed invention. We also disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from Pfirsch’s rounded corners, which, presumably, are formed as an incidental result of lithography. On the contrary, the Examiner found (and Patent Owner acknowledged) that Pfirsch has rounded corners. Ex. 1002, 276, 295, 302. As Patent Owner correctly points out, the claims were amended during prosecution to include a “circular” contact to distinguish over Pfirsch’s square contact. See id.

“is ‘known’ is not sufficient for a motivation to combine.” PO Resp. 47. However, the motivation-to-combine analysis is a flexible one, and the “known-technique” rationale is adequate to show a motivation to combine. For example, “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 his or her skill.” KSR, 550 U.S. at 417; see also Intel Corp. v.

Cir. 2021) (“If there’s a known technique to address a known problem using ‘prior art elements according to their established functions,’ then there is a motivation to combine.”). Here, as discussed above, the record shows that top view rounding was a known technique to eliminate corners, and that corners were a known problem (e.g., corners tend to reach undesirable higher peak electric field leading to premature breakdown voltage). See, e.g., Ex. 1003 ¶¶ 37, 39, 42– 44, 55–57, 122, 133, 135–141; Ex. 1005, 7:57–8:4; Ex. 1006, 1:18–21, 2:19–39, 5:3–17, Figs. 6A–8B; Ex. 1011, 1:29–41; Ex. 1012; PO Resp. 13, 46 (citing Ex. 1011, 1:34–40); Ex. 2021 ¶ 87.

“We agree that Kobayashi’ s Figure 5A solely cannot be relied upon as disclosing the claimed diameter. See Hockerson-Halbertstadt, Inc. v. Avia Group Int'l, 222 F.3d 951, 956 (Fed. Cir. 2000) (patent drawings not designated as being drawn to scale cannot be relied upon to define precise proportions of elements if the specification is completely silent on the issue). However, we do not agree that Petitioner failed to show Kobayashi suggests the recited diameter. We disagree with Patent Owner’s assertion that Dr. Liu’s “vague, purported ‘design considerations’” are “unsupported.” PO Resp. 43. Although Kobayashi is silent on the width/diameter of the trench contact in Figure 5A, Kobayashi discloses trenched gates having dimensions below 0.5 μm, which demonstrates that it was known in the art, and required no more than an exercise of ordinary skill in the art, to create trenched features of widths well below 1 μm. Kobayashi also discloses that the width of each trench, and the distance between the adjacent trenches (which includes the trench contact), must be selected to optimum sizes . . . [and] these sizes . . . have some degrees of freedom.” Ex. 1005, 7:42–48. This demonstrates a POSITA would seek to optimize trench contact width or diameter. Dr. Liu’s testimony regarding design considerations suggests the desirability of a reduced diameter trench contact, e.g., to minimize the width of the trench contact for purposes of easier filling, to minimize the total width of the unit cell, and to minimize manufacturing time by reducing etch back time. See Ex. 1003 ¶¶ 111–114. As Patent Owner acknowledges, “there is always a motivation to speed up the fabrication process or shrink feature sizes of semiconductors.” PO Resp. 43 (citing 2021 ¶ 131). However, contrary to Patent Owner’s arguments, these are not generic motivations “untethered” from Kobayashi. Id. Indeed, Kobayashi directly addresses the fabrication process (including new techniques to obtain trench widths under 0.5 μm) and the need to optimize the size of trench gates and the space in between (which includes the trench contact). Ex. 1005, 7:43–54, 7:19–9:53. Patent Owner also argues that Petitioner presents no evidence that modifying Kobayashi to have a diameter smaller than 1 μm is predictable. PO Resp. 44. We disagree. As discussed above, Petitioner points to Kobayashi’s teachings that the sizes are to be optimized and that the trench gate width is smaller than 0.5 μm, which suggests making other trench features of that width was within ordinary skill. Ex. 1003 ¶ 112. Furthermore, Kobayashi’s silence as to the dimensions of the trench contact suggests that the trench contact diameter dimension is likely in the ballpark of the other explicitly disclosed trenched feature dimensions and is a matter of routine optimization. In addition, Patent Owner advances no persuasive evidence that the claimed diameter produces unexpected results or is otherwise critical. Patent Owner also argues that reducing trench contact diameter has downsides (i.e., reduced ease of filling for metal plugs and reduced current carrying capacity) not addressed by Petitioner; however, Petitioner is not required to address those tradeoffs in its Petition, and we do not see how those tradeoffs would prevent the proposed combination. PO Resp. 44; see Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.”); Winner Int'l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.”). Here, Dr. Liu listed numerous benefits of having a reduced diameter, which weigh against the potential downsides raised by Patent Owner. Ex. 1003 ¶¶ 111–114. Moreover, we do not see how the downsides/tradeoffs prevent modifying Kobayashi in the manner suggested when the same tradeoffs appear to be applicable to the ’409 patent.

Indeed, the evidence suggests (and Dr. Horenstein acknowledges in his first declaration) that at least a component of flux will escape the core of even a traditional transformer. See Ex. 1032 ¶¶ 45–47; Ex. 1044, 6; Ex. 2001 ¶ 27.

“(4) Analysis We are persuaded by Petitioner’s argument that during the alignment process in Odachi corresponding to claim 13, there is a “spaced distance between the primary inductive coupler [230] and the secondary inductive receptacle 2” which is “reduced gradually and electromagnetic induction occurs between the coupler to the receptacle when the former coupler comes close to the latter receptacle.” Ex. 1005, 6:1–6. Thus, prior to any contact or precise alignment between the two cores, “an electromotive force is induced in the secondary coil 4 and this induced force is increased with the decrease in the spaced distance.” Id. at 6:6–8. At least in that spaced configuration, the evidence of record suggests that primary coil 31 produces a near-field component of flux into free space (the air space between the coils where there is no intervening core material) that is intercepted by secondary coil 4 to effect resonant inductive coupling, and that secondary coil 4 intercepts and receives the near-field component of flux in free space that is generated by primary coil 31 to effect resonant inductive coupling. See Ex. 1032 ¶¶ 48–52, 55. Thus, we find that Odachi discloses a “transmitting antenna” (coil 31) and a “receiving antenna” (coil 4) under Patent Owner’s proposed construction. We would reach the same finding under Petitioner’s proposed broader construction because the evidence suggests that Odachi’s coils 31 and 4 would have been considered “antennas” under the parties’ uncontested definition of that term, which is “a device that radiates and/or receives radio waves.” See id. ¶¶ 43–47, 53–54; Ex. 1032 ¶ 15 (Dr. Allen agreeing with this definition of “antenna”); Ex. 2001 ¶ 25 (Dr. Horenstein agreeing with this definition of “antenna”)). In addition, Petitioner persuasively shows that the free space between Odachi’s coils in the spaced configuration includes the “near-field region,” which includes the induction field around primary coil 31. See Ex. 2006, 498; Ex. 1045, 5:4–7; Ex. 1032 ¶¶ 53–54). Dr. Horenstein’s testimony does not contradict this. Although he points out that there are separate terms for inductive, near, and far fields, he also acknowledges that “[t]he region of space closer to the antenna than the far field is the near-field region.” Ex. 2010 ¶ 37 (citing Ex. 2006, 275).8” slip op. at 22

“allocating bandwidth as part of its resources and that, in light of Wright, a person of ordinary skill in the art would have had reason to make this allocation for each of the links in of the physical topology (see Ex. 1006 ¶ 18 (“bandwidth allocation at each link”)) using information from both (1) the bandwidth requirements of Baker’s logical connections and (2) the mapping between Baker’s logical and physical topologies. As Petitioner persuasively argues, we find that Wright’s teaching of further details on ensuring the availability of bandwidth, in a similar context, would have been sufficient motivation for a person of ordinary skill in the art to incorporate Wright’s teachings into Baker’s method. We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology.

“For reasons explained in the Petition and Petitioner’s Reply, we agree with Petitioner that the Baker–Wright–Holender ’699 combination teaches summing the two bandwidths determined in “allocating” steps 12.5 and 12.7 to determine a total allocation for each of the physical links—motivated by the known need to ensure that bandwidths do not exceed the available physical link capacity. We disagree with Patent Owner that Holender ’699’s discussion of summing is merely describing a physical constraint. Holender ’699 teaches normalizing the logical link capacities, which requires summing the logical link capacities. See Ex. 1007, 8:38–51. We credit Dr. Houh’s testimony that this “confirms that [Holender ’699’s] teachings about summing are not simply ‘explaining a physical constraint,’ but actually performed.” Ex. 1036 ¶ 61.

“Relying on Dr. Houh’s testimony, Petitioner argues that a person of ordinary skill in the art “would have had a working knowledge of the networking art that is pertinent to the ’431 patent, including network communications techniques and bandwidth management methodologies,” and “would have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent, and two years of professional experience relating to network communications including the use of logical topologies and bandwidth management. Lack of professional experience can be remedied by additional education, and vice versa.” Pet. 3 (citing Ex. 1003 ¶¶ 18–20). Patent Owner adopts Petitioner’s proposed definition of the level of ordinary skill. PO Resp. 3.

“We find Petitioner’s arguments persuasive that Baker teaches allocating bandwidth as part of its resources and that, in light of Wright and Holender ’699, a person of ordinary skill in the art would have had reason to make this allocation for each of the links in of the physical topology (see Ex. 1006 ¶ 18 (“bandwidth allocation at each link”)) using information from both (1) the bandwidth requirements of Baker’s logical connections and (2) the mapping between Baker’s logical and physical topologies. As Petitioner persuasively argues, we find that Wright’s teaching of further details on ensuring the availability of bandwidth, in a similar context, would have been sufficient motivation for a person of ordinary skill in the art to incorporate Wright’s teachings into Baker’s method. Holender ’669 provides further supporting disclosure. We also determine that whether Wright, itself, teaches a mapping step is not the determining factor because Petitioner relies on Baker, not Wright, for teaching mapping limitation 1.4. Nevertheless, Wright does teach allocating bandwidth using the same information that would be available as a result of Baker’s mapping, including the logical (“restricted”) topology and the physical links associated with that topology. In particular, we agree with Petitioner that a person of ordinary skill in the art would have understood that allocating bandwidth to the physical links (step 510 of Figure 5) requires knowing which physical links correspond to Wright’s restricted topology. See Pet. 33; Pet. Reply 22–23; Ex. 1007 ¶ 17; Ex. 1003 ¶¶ 94–96; Ex. 1036 ¶¶ 49–51. We also disagree with Patent Owner that Petitioner has failed to adequately explain how a person of ordinary skill in the art would have modified Baker’s method to apply Wright’s teachings on bandwidth allocation, such as how Baker’s head node N0 would have been modified. See PO Resp. 31–32. Based on the level of ordinary skill and the level of detail in Baker, Wright, and the ’431 patent, and crediting Dr. Houh’s testimony, we find Petitioner’s argument persuasive that such modification would have been within the capability of someone of ordinary skill in the art. See Pet. 9–12 (citing Ex. 1003 ¶¶ 42–46, 48; Ex. 1021 ¶¶ 100–101).

“We agree with Patent Owner. Petitioner has not shown that any of the integrated circuits cited in the Petition would have been able to include the claimed acoustic model memory. Further, we find, contrary to Petitioner’s contention, that Patent Owner did not admit that procuring a processor and a memory capable of storing an acoustic model memory fabricated on an integrated circuit was within the level of ordinary skill. To the contrary, throughout the entire proceeding, Patent Owner has consistently argued that the claimed “calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” was unknown in the prior art. Petitioner has not shown that using the prior art elements relied on in the Petition according to their established functions would have resulted in “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1. In summary, Petitioner relies on Mozer to teach the benefits of fabricating a calculating apparatus and an acoustic model memory on the same integrated circuit, but Mozer does not teach a calculating apparatus and an acoustic model memory fabricated on the same integrated circuit. Further, the benefits of Mozer identified by Petitioner are benefits that both Mozer and Smyth already have, without fabricating the calculating apparatus and the acoustic model memory on the same integrated circuit. Also, even if Petitioner had shown there was a reason to combine Smyth and Mozer, Petitioner does not persuasively show that the combination teaches “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1.

Pet. 26 (citing Ex. 1003 ¶¶ 142–143). The Reply further explains that in view of Sharpe’s teachings, the username is the most obvious design choice because a username is one such unique identifier. Pet. Reply 3. We determine the discussion in the Reply describing the use of a username rather than the user’s personal name as a design choice for use as a primary key (Pet. Reply 3–4) is the same argument as, or a fair extension of, these contentions in the Petition. For these reasons, we do not find the ground of obviousness over” slip op. at 20

“Absent a recitation of order, or an order mandated by grammar or logic, the steps of a method claim are not construed to require a particular order. See, e.g., Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003). Patent Owner argues that the steps of claim 1, a method claim, must be performed in sequential order. PO Resp. 13–16. Without commenting on or conceding Patent Owner’s proposal, Petitioner contends that “the trial grounds meet this proposed construction.” Pet. Reply 24–25; Tr. 8:25–11:16. Our record does not reflect any indication that Patent Owner’s proposed construction requiring the sequential ordering of the method steps is not at least encompassed by the correct construction of claim 1. Because of this, and because Petitioner agrees that the arguments in the Petition meet this construction, we accept Patent Owner’s construction as correct for the purposes of this Decision.” slip op. at 10

“We do not agree with Patent Owner that Petitioner’s showing uses the same sound data to teach the “first sound data” of limitation 1.a and the “second sound data” of limitation 1.c. Patent Owner is correct that Rosenberg’s claim 5 describes the determination of a volume threshold based on the volume of the ambient audio signal in which characteristic form(s) (e.g., the name of the user of the media player) are present. Ex. 1006, 13:66–21, 14:28–30. However, the Petition describes using Fu’s “predetermined threshold” in combination with Hart-787’s device, which attenuates audio output of a device upon detecting a user’s utterance intended to gain the attention of the device, in order to “include adjusting the audio output volume of a wirelessly-linked audio-producing device when the voice-controlled device determines that the ambient noise level at the time a Ex. 1004, 2:22–37, 5:61–6:10, 9:18–25; Ex. 1005 ¶¶ 24, 32, 54; Ex. 1003 ¶¶ 88–89). Petitioner further proposes including a threshold that is advantageously based on the environment in which the device is operating as described in Fu, for example to respond to differing levels of noise at different times of day. Id. at 26, 29–30, 40 (citing Ex. 1006, 10:42–67, 14:28–30; Ex. 1003 ¶¶ 48–53, 55, 58, 87, 91, 107–109). We agree with Petitioner that Patent Owner’s arguments address the references individually instead of addressing the combination of the teachings proposed in the Petition. See Pet. Reply 8, 13–14; see also Dec. on Inst. 21–22, 23–24, 25–26. The Petition relies upon a combination of elements of Hart-787 with the predetermined threshold as taught in Fu and with establishing such a threshold based on the operating environment of a device as in Rosenberg. Pet. 26–31, 34–41. Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition. We also find that the preponderance of the evidence supports Petitioner’s showing regarding the motivation to combine the references.” slip op. at 23

See Pet. 23 (citing Ex. 1004, 5:47–51; Ex. 1003 ¶ 82), 43–44 (citing Ex. 1004, 1:67–2:7, 2:26–27, 5:47–51; Ex. 1003 ¶ 118). In addition, Petitioner shows that these control signals were well-known in the art and would have been known to one of ordinary skill in the art at the time of the invention, supporting its showing with additional testimony from its declarant. Id. at 44 (citing Ex. 10183, 2:39–47, 5:35–38; Ex. 10194 ¶¶ 3, 13; Ex. 1003 ¶¶ 44–45, 118). We conclude Petitioner’s evidence regarding the showing in Hart-787 is sufficient with respect to this point. Hart-787 describes altering a signal sent to the speaker to attenuate the audio from that speaker. Ex. 1004, 1:67– 2:1. Petitioner’s declarant testifies that using transmitted control signals to do this would have been known to one of ordinary skill. Ex. 1003 ¶¶ 44–45, 82, 118. We consider Petitioner’s evidence regarding what one of ordinary skill in the art would have understood from Hart-787’s disclosure to be sufficient for the showing regarding the “causing one or more commands to be automatically issued to the controllable appliance to thereby cause” that appliance to transition to a lower volume level, as required in limitation 1.e.
