    “Petitioner contends that the challenged claims do not need construction to demonstrate unpatentability. Pet. 14. Petitioner, however, notes that the parties in the ITC proceeding identified above dispute the meaning of several claim terms. Id. (citing Ex. 1026). Petitioner specifically notes that “the parties dispute what is required of independent claims 1, 5, and 16 to ‘determin[e] how many pixels’ to filter in each block.” Id. (citing Ex. 1026, 6–7). Petitioner argues that “ITC Respondent Lenovo mathematical basis (no relationship) with the pixel values of the pixels in said neighboring block’” (id. (citing Ex. 1026, 6–7)), but Patent Owner “contends that no construction is necessary,” “and the ‘plain meaning’ does not foreclose some ‘mathematical basis’ existing as long as separate decision values are calculated for each block” (id.

    “Furthermore, we are not persuaded that modifying Aksu in view of Gonzalez in the manner proposed by Petitioner overcomes this problem. As noted above, Petitioner asserts that, in the proposed combination, one of ordinary skill in the art “would have understood that the Laplacian’s output would be compared directly to a threshold based on β—just like Aksu’s difference calculations—to determine how many pixels to filter.” Pet. 60 (citing Ex. 1019, 13:15–19; Ex. 1003 ¶¶ 406–410). We disagree with this assertion, however, because it relies on erroneously equating the output of calculations (i.e., |r1-rj| and |r1-ri+1|). In other words, Aksu’s difference calculations, although used in setting dr, are not the same as dr; and we are not persuaded that one of ordinary skill in the art would have considered comparing Gonzalez’s Laplacian output to threshold β because Aksu discloses comparing its difference calculations to β. As noted above, we are not directed to any disclosure in Aksu of comparing dr to β. In addition, Dr. Schonfeld’s testimony on this point is not persuasive. Specifically, Dr. Schonfeld testifies that “dr can simply be defined as the output of the Laplacian (dr=|r3-2r2+r1|), and dr could be directly compared to a threshold based on β.” Ex. 1003 ¶ 408 (underline emphasis added). This testimony, however, is entitled to little weight because Dr. Schonfeld fails to provide a sufficient underlying basis for his opinion. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Nobel Biocare Services AG v. Instradent USA, Inc., 903 F.3d 1365, 1382 (Fed. Cir. 2018) (explaining that the Board can reject arguments based on expert testimony that lacks specificity or detail). Moreover, opining that output of the Laplacian, dr, could be directly compared to β does not establish sufficiently that one of ordinary skill in the art would have been motivated to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed.

Rather, the PRM would operate within its normal range.” Pet. 50 (citing Ex. 1003 ¶ 144) (emphasis added). But Petitioner’s description of the proposed combination—in which “the PRM would never reach an over-current condition”—cannot be reconciled with Petitioner’s showings for the “over-current” limitations, which require, e.g., “when the resonant converter generates the over-current” (limitation [1c]). For example, for limitation [1c], Petitioner states “when the VTM exceeds its normal operating current, the PRM (with a duty cycle current limiter as taught by Hwang) would reduce its duty cycle, which would reduce its output voltage and output current, and thus reduce the input voltage and current to the VTM.” Pet. 55–56 (citing Ex. 1003 ¶ 158). But Petitioner and its declarant both state that in the combination proposed in Ground 2, “the PRM would never reach an over-current conduction.” Pet. 50; Ex. 1003 ¶ 144; see Pet. 59 (addressing similar language in limitation [1c]), 61 (addressing limitation [13c]), 63 (addressing limitation [17d]). Petitioner does not explain how those positions can be reconciled, nor does Petitioner adequately explain, much less support, a claim interpretation that would be satisfied by a proposed combination in which the resonant converter never generates an over-current.

    “communication device for multiplexing signals.” Ex. 1001, 12:2–3 (emphasis added). The language in the preamble does not support adopting Petitioner’s proposed interpretation of “multiplexing” to mean that “the connections may be used simultaneously or sequentially for combining multiple data paths into a single path,” because signals are being multiplexed, not connections or data paths.

    “show by a preponderance of the evidence that Yegoshin teaches or would have been understood to reasonably suggest “multiplexing signals” and that Bernard “includes or operates as a multiplexer for combining the data packets.” See Pet. 32–40. Because Petitioner does not show multiplexing signals in any of the asserted references, Petitioner does not show by a preponderance of the evidence that its proposed combination of Yegoshin, Bernard, Johnston, and Preiss would have rendered obvious “[a]n IP-enabled communication device for multiplexing signals,” as recited by claim 1. Also, because Petitioner fails to show Yegoshin teaches or would have been understood to reasonably suggest multiplexed signals and fails to show that Bernard “includes or operates as a multiplexer for combining the data packets,” Petitioner’s asserted motivation to modify Yegoshin in view of Bernard for “multiplexing signals” lacks rational underpinning. Weighing the underlying factual determinations, a preponderance of the evidence does not persuade us that claim 1 of the ’075 patent is unpatentable over Yegoshin, Bernard, Johnston, and Preiss.

    “Though Petitioner asserts that there are a “limited number of design options” and that it would have been obvious to combine the different components of Lin, Petitioner does not establish that a controller configured to perform DPI analysis on packets was a known solution, and thus one of the limited design options. As discussed in KSR: When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that is was obvious under § 103. KSR, 550 U.S. at 421. Besides asserting the combination would have been “obvious to try,” Petitioner provides no other analysis or reason why one of skill in the art would have modified the teachings of Lin to obtain the claimed controller.

    “Further, we find the testimony of Patent Owner’s declarant more persuasive based at least on his consideration of Swenson as a whole and his more detailed analysis and explanations. For example, Patent Owner’s declarant explains in detail why, “[i]n the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets:” Furthermore, Swenson discloses that the steering device 130 “sends an ICAP request message 516 comprising [a] HTTP GET request header and a portion of the [HTTP] response payload to the network controller 140, which inspects the message to determine whether to monitor the flow or optimize the video.” Ex. 1007 [0065]. In the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets. The reference to a HTTP request and response “header” and “payload” are thus not references to the header and payload of a packet. A POSA would know that despite common parlance references to “HTTP packets,” HTTP does not pertain to individual packets, whereas packet transmission is governed by the TCP protocol. HTTP utilizes TCP to exchange data such that information may be used by an end user (e.g., a video or audio stream). Even assuming that Swenson’s controller were analyzing the header and payload of an HTTP request/response, a POSA would understand that this analysis is not at the packet but at the flow level and thus does not constitute deep packet inspection. Ex. 2025 ¶ 69. Petitioner’s declarant merely responds by reiterating what was previously stated: Swenson is explicit in stating that its inspection techniques include inspection of “a portion of the [HTTP] response payload.” . . . A POSA would have understood the analysis of the “response payload” to be DPI by a DPI-capable controller, as DPI refers to monitoring the payload of a packet.” slip op. at 15

    “a POSA would have understood that one of the limited number of design options would have been to implement the security service as part of a controller configured to perform DPI analysis on packets, and a POSA would have had a reasonable expectation that the controller would have been successful in performing DPI analysis. Id. at 18–19 (citing Ex. 1004 ¶ 79 (making an identical statement)). No additional discussion, explanation, or evidence on these points were provided at the Petition stage. Patent Owner argues that: The mere fact that the security service may share certain common technical characteristics with the controller (i.e., its connection to the network switch and the hardware in which these two separate entities are implemented) cannot in and of itself suggest to a POSA that the function carried out by the security service should also be performed by the controller or that the controller should be configured to perform that function (i.e., deep packet inspection). PO Resp. 21–22 (citing Ex. 2025 ¶¶ 54–55). We agree. Though Petitioner asserts that there are a “limited number of design options” and that it would have been obvious to combine the different components of Lin, Petitioner does not establish that a controller configured to perform DPI analysis on packets was a known solution, and thus one of the limited design options.
