“Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

“5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364, 1369 (Fed.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

Reply 1–2 (district court construing the term to mean “the time the image sensor collects and integrates signal from the scene”). The specification states that the integrated photo-charge “is directly related to the time the image sensor collects and integrates signal from the scene,” and that “[t]his is known as integration time.” Ex. 1001, 4:4–7.

“We construe “during a frame” to mean the period during which data for a single frame of an image is captured. The limitation is satisfied where the per-channel integration time is effectuated during the frame; it does not require that the integration time be re-determined mid-frame, nor does it require actuation of a “charge integration switch.” The specification’s only use of the phrase confirms this reading: “each camera channel is controlled during a frame under an independent integration time.” Ex. 1001, 3:45–50. Consistent with that usage, the specification describes selecting an integration time for each channel and then integrating the photo-signal “within a single frame of data,” and describes placing the charge-integration switch in a state to allow charge to accumulate for the selected period and then transferring the accumulated charge upon completion of the integration period. Id. at 4:51–54, 11:3–18. We decline Patent Owner’s proposal to require in-frame actuation of a charge-integration switch, for the same reason we decline to import that structure into “integration time.” We also decline to read the phrase to require mid-frame re-determination of the integration time, because the patent’s own embodiment selects an integration time and then integrates charge during the frame under that selected time. Ex. 1001, 4:51–54, 11:3– 18. So construed, “during a frame” is not redundant of the independentclaim limitation: it adds that the per-channel control occurs within a single frame (intrascene), as distinct from adjustment from one frame to the next (interscene).” slip op. at 15

“Based on the record before us, we agree with Petitioner that “on a surface” should be interpreted in line with the definition of “on” set forth in the ’711 patent. Ex. 1001, 4:1–6. We particularly note that the ’711 patent states that “‘on’ . . . should be interpreted in the broadest manner” and that “on” is not limited to “directly on.” Id. Instead, the ’711 patent states that “‘on’ also includes the meaning of ‘on’ something with an intermediate feature or layer therebetween.” Id. Patent Owner agrees that this definition controls the “standalone ‘on’” term such that A may be on B even if there is an intervening layer between them. Tr. 55:8–11 (“The standalone ‘on,’ we agree in the context of the patent, you can have intervening layers. I think the patent is clear about that.”). Claim 14 recites that the etch-stop layer is “on” something; i.e., “on a side surface and a top surface of each step.” Ex. 1001, 16:20–22. Patent Owner agrees that a surface is a “something.” Tr. 56:5–8 (“surface obviously is a something”). Substituting the “a “‘on’ something with an intermediate feature or layer therebetween” results in claim 14 reading as, “on a surface with an intermediate feature or layer therebetween.” Unlike “directly on,” which specifies the relation between two things, “a surface” may merely indicate the thing that something is “on,” particularly when “on” is “interpreted in the broadest manner” as expressly required by the ’711 patent.” slip op. at 7

“Although Dr. Campbell testified in his deposition in response to Petitioner’s counsel that “on the surface” requires direct contact with the surface, his interpretation was based on “embodiments of” the patent rather than a general understanding of a person skilled in the art confronted with that term. Ex. 1027, 122:6–25, 124:6–23 (“I’m not sure if there are other sources for that, but it was on the ’711, so I’ve taken it there.”). Dr. Campbell, upon questioning from Patent Owner’s counsel, later stated that “an expert in semiconductor fabrication” would understand “on the surface” to mean “contact between one layer and another . . . with nothing in between.” Id. at 146:25–147:6. However, Dr. Campbell did not explain why such an interpretation is particular to the semiconductor fabrication art, or provide other explanation or support for this statement, which is in tension with the definition of “on” in the ’711 patent. Accordingly, we significantly discount the weight accorded to that statement. Phillips, 415 F.3d at 1318 (stating, “conclusory, unsupported assertions by experts as to the definition of a claim term are not useful to a court. Similarly, a court should discount any expert testimony ‘that is clearly at odds with the claim construction mandated by the claims themselves, the written description, and patent.’”). On balance, Dr. Campbell’s testimony is best understood as a description of certain Figures of the ’711 patent rather than a representation of an ordinarily skilled person’s understanding of the term “on the surface.” See Ex. 2009 ¶ 47 (describing Figs. 1, 3, and 4 as depicting layers in contact with the underlying layer or substrate). For example, Dr. Campbell describes Figure 9A as having a barrier layer “on and directly contacting the top and side surfaces of each step.” Id. ¶ 28 (emphasis added) (citing inter alia Ex. 1001, 7:6–67). Dr. Campbell does not explain why, beyond the fact that many Figures show layers as adjacent and in contact, a person of ordinary skill in the relevant art would understand those Figures to limit the claim language rather than illustrating particular embodiments that fall within a broader scope of claims 14 and 15. See Hill-Rom Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed.

“We agree with Petitioner that Kim’s first and second section are described as compatible, not mutually exclusive, embodiments.

Ex. 1005 ¶ 184 (emphasis added). Patent Owner argues that only the embodiments in Figures 17A–22B describe an etch-stop layer and a barrier layer (as claimed), and that the language cited for a gate-stack-on-top configuration (e.g., Ex. 1005 ¶¶ 90, 91, and 240) is “conspicuously absent from the description of Figures 17A–22B.” PO Resp. 20 (citing Ex. 2009 ¶ 36). However, Figures 17A–22B do not further address the underlying staircase structure that was detailed in the descriptions of the Figures 4 through 15 embodiments. While Figures 17A–22B show a gate-stack-on-bottom configuration, this merely continues the gate-stack-on-bottom illustrations that were used in all of the previous Figures, even for those in which it is undisputed that a gate-stack-on-top configuration is a described alternative.

“We are persuaded by Petitioner that the lower volume of Toyama’s dielectric fill portion teaches the isolation structure and the upper volume of Toyama’s dielectric fill portion teaches the dielectric structure. First, the structure may be the same material; i.e., SiO2. Ex. 1001, 10:37–40 (isolation structure 233 filled with SiO2), 10:46–47 (dielectric structure can include SiO2, and can include the same material as dielectric layer 230), 10:12–14 (dielectric layer 230 is formed of SiO2). Second, the ’378 patent indicates that the dielectric structure may be “aligned to” and “in contact with” the isolation structure. Id. at 10:30–36. Thus, the two structures of the ’378 patent may appear as two aligned and contacting structures; e.g., a single column of the same material. Third, the ’378 patent specification describes that the dielectric structure and a top portion of the isolation structure may be formed in the same deposition step. When etching the opening 600 that is to be filled with dielectric structure 232, “opening 600 may extend partially into STI structure 233;” i.e., “the etch process used to form opening 600 may also remove (recess) portion of the top surface of STI structure 233.” Id. at 15:12–20; Fig. 6. Then, “opening 600 can be filled with a dielectric layer 702,” which may be the same SiO2 material as the isolation structure, and “[a]s a result, dielectric structure 232 is formed.” Id. at 15:42–54. Thus, the ’378 patent describes a dielectric structure that partially replaces or re-forms, with the same material, its isolation structure. The ’378 patent does not mention whether this results in a dielectric structure that extends into the isolation structure or an isolation structure re-filled to its original height, and it would not appear to matter because both structures may be composed of the same material. The ’378 patent’s indifference to the exact boundary between dielectric structure 232 and isolation structure 233 during formation from the same material indicates that these structures need not be taught by distinct elements. applicable only if the ’378 patent describes that the isolation region and dielectric structure were formed as a single unitary structure. PO Resp. 51; PO Sur-reply 16–18. Retractable Techs. focuses on whether the two elements at issue “could be formed as an integral structure in the first instance,” not whether they were formed integrally. Retractable Techs., 653 F.3d at 1304 (“The specifications further disclose a method to couple the two structures . . . to allow some diffusion or insipient melting to occur where they touch . . . . This passage suggests that [the structures] could be formed as an integral structure in the first instance”). Retractable Techs. looks to whether the specification suggests that the claim terms require separate structures. Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1232 (Fed. Cir. 2011). Patent Owner’s focus on whether the claimed structures were disclosed as being separately formed disregards the issue of whether the separately claimed structures require specific methods of forming those structures. Here, as in Retractable Techs. and Powell, the Specification does not indicate any particular structure or function for the structures that results from their separate steps of deposition. Thus, as held in Retractable Techs. and Powell, the two portions of Toyama “need not be two separate parts” to teach two separate claim limitations. Retractable Techs., 635 F.3d at 1303–04. Consequently, we determine that the claim language does not support a requirement that these structures be separate and distinct. Patent Owner’s further arguments are not availing. Contrary to Patent Owner’s argument, in our “Third” point, supra, we do not state that the isolation structure and the dielectric structure are formed in the same deposition step.

However, because Petitioner relies upon a dielectric structure that includes other portions of Mushiga that Patent Owner does not dispute to be on the asserted isolation structure, the dispute is whether Petitioner is correct to include multiple components as part of a single dielectric structure, and not whether spacer 586 is on an isolation structure. Id. Because Petitioner’s assertions and our determination would be unaffected by its proposed construction, we need not construe this term. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am.

“Patent Owner’s citations to the Specification do not support its proposed construction. Patent Owner relies on multiple embodiments, only one of which describes a substrate “with” an isolation structure. PO Resp. 21 (citing Ex. 1001, 22:27–28). For example, one of Patent Owner’s cited embodiments recites “on” an isolation region, but Patent Owner specifically argues that the “on” embodiment does not apply to the claimed “with” embodiment. Id. at 22 (denying that “the ‘with’ relationship encompasse[s] the ‘on’ relationship”). Only one of the embodiments cited is clearly within the scope of the “with” claim language, and that embodiment describes no more than the claim language itself. Ex. 1001, 22:27–28. Moreover, Figure 2, cited by Patent Owner, is an illustration “according to some embodiments,” but is not described as depicting all embodiments. Ex. 1001, 3:35–36. These other embodiments need not be included in claim 15’s “with” language because other claims (not at issue in this proceeding) specifically recite language from other embodiments. Ex. 1001, 23:20–21 (“a dielectric structure on an isolation region of the substrate”), 23:58 (“forming an isolation structure on a substrate”). Thus, the specification of the ’378 patent does not limit “a substrate with an isolation structure” in claim 15 to “part of” an isolation structure, such as in a shallow region or other partial-depth portion of the substrate. Because neither the language of claim 15 nor the Specification indicates a narrower meaning, we agree with Petitioner that the phrase “a Patent Owner argues that the plain meaning of “with” is “having” or “inclusive of.” PO Sur-reply 2 (citing Ex. 1038, 7). Citing the same dictionary, Petitioner argues that the plain meaning of “with” includes objects that are separate. Pet. Reply 3 (stating, “In the sentence ‘Alice went to school with Bob,’ it would be nonsensical to interpret that to mean that Bob is part of Alice.”) (citing Ex. 1038, 7). The cited definition of “with” states that it may indicate “accompaniment,” such as “went there [with] her,” as well as combination (“milk [with] honey”). Ex. 1038, 7. Based on the evidence and arguments presented, we determine that the phrase “a substrate with an isolation structure” should be given its plain meaning, which includes accompaniment (A is accompanied by B) as well as combination (A is part of B, or A and B are a part of C).” slip op. at 9

“We are persuaded by Petitioner that the lower volume of Toyama’s dielectric fill portion teaches the isolation structure and the upper volume of Toyama’s dielectric fill portion teaches the dielectric structure. First, the ’378 patent indicates that both the dielectric structure and the isolation structure may be the same material; i.e., SiO2. Ex. 1001, 10:37–40 (isolation structure 233 filled with SiO2), 10:46–47 (dielectric structure can include SiO2, and can include the same material as dielectric layer 230), 10:12–14 (dielectric layer 230 is formed of SiO2). Second, the ’378 patent indicates that the dielectric structure may be “aligned to” and “in contact with” the isolation structure. Id. at 10:30–36. Thus, the two structures of the ’378 patent may appear as two aligned and contacting structures; e.g., a single column, of the same material. Third, the ’378 patent specification describes that the dielectric structure and a top portion of the isolation structure may be formed in the same deposition step. When etching the opening 600 that is to be filled with dielectric structure 232, “opening 600 may extend partially into STI structure 233;” i.e., “the etch process used to form opening 600 may also remove (recess) portion of the top surface of STI structure 233.” Id. at 15:12–20. Then, “opening 600 can be filled with a dielectric layer 702,” which may be the same SiO2 material as the isolation structure, and “[a]s a result, dielectric structure 232 is formed.” Id. at 15:42–54. Thus, the ’378 patent describes a dielectric structure that partially replaces or re-forms, with the same material, its isolation structure. The ’378 patent does not mention whether this results in a dielectric structure that extends into the isolation structure or an isolation structure re-filled to its original height, and it would material. The ’378 patent’s indifference to the exact boundary between dielectric structure 232 and isolation structure 233 during formation from the same material indicates that these need not be taught by distinct elements. We do not agree with Patent Owner that Retractable Techs. is applicable only if the ’378 patent describes that the isolation region and dielectric structure were formed as a single unitary structure. PO Resp. 50; PO Sur-reply 9. Retractable Techs. focuses on whether the two elements at issue “could be formed as an integral structure in the first instance,” not whether they were formed integrally. Retractable Techs., 653 F.3d at 1304. (“The specifications further disclose a method to couple the two structures . . . to allow some diffusion or insipient melting to occur where they touch . . . . This passage suggests that [the structures] could be formed as an integral structure in the first instance”). Retractable Techs. looks to whether the specification suggests that the claim terms require separate structures. Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1232 (Fed. Cir. 2011). Patent Owner’s focus on whether the claimed structures were disclosed as being separately formed disregards the issue of whether the separately claimed structures require specific methods of forming those structures. Here, as in Retractable Techs. and Powell, the Specification does not indicate any particular structure or function for the structures that results from their separate steps of deposition. Thus, as held in Retractable Techs. and Powell, the two portions of Toyama “need not be two separate parts” to teach two separate claim limitations. Retractable Techs., 635 F.3d at 1303– 04. Consequently, we determine that the claim language does not support a requirement that these structures be separate and distinct.” slip op. at 32

Patent Owner next contends that Kido does not disclose a first payout that is “for the spin of the roulette wheel.” Prelim. Resp. 29. Patent Owner’s argument is premised on the cumulative nature of Kido’s Prog bonus – it builds with every spin of the roulette wheel until won. Id. (“Each time the wheel is spun, 0.5% of the amount wagered is added to the progressive jackpot, and thus, the jackpot’s value reflects multiple spins of the roulette wheel.”). Thus, according to Patent Owner, the value of the jackpot is determined using multiple spins of the roulette wheel and is not “for a spin of the roulette wheel” as claimed.” Id. at 30. The claims, however, only require a first payout that is higher than a second payout. Nothing prohibits the higher payout from accumulating from prior spins of the roulette wheel because, when it is actually won, it will be for that last spin of the roulette wheel. Ex. 1005, 8:35–36 (“indicating that the first player is to be paid at the first payout for the spin of the roulette wheel”). Regardless of how Kido’s Prog bonus accumulated, it is paid for a spin of the roulette wheel – at that juncture Kido discloses each claim element. Anticipation occurs when a prior art reference discloses every element of a patent claim at a point in time, as Kido does with a single spin of the roulette wheel that pays the Prog bonus. As persuasively explained by Petitioner, “the steps of Figure 12 (including A13) occur within a single round of roulette, for a single spin of the roulette wheel, until the routine ‘returns to the step of A1 and is transited to a next game.’” Pet. 39 (quoting Ex. 1007 ¶ 233).” slip op. at 13
