“Petitioner also fails to provide sufficient rationale and a reasonable expectation of success in combining Krishnan and Lee to arrive at a quality assessment neural network configured to receive an image. See Pet. 34–37. For example, the Petition lacks an explanation of why a POSITA would have been motivated to modify Krishnan’s quality assessment neural network to be configured to receive an image, instead of extracted features, in view of Lee’s image-receiving category classifying neural network. Id. Without such further explanation, Petitioner’s challenge falls short. Petitioner’s argument that neural networks for image quality assessment were “well-known” is not persuasive—it does not address the particular scope of limitation 1i, which also requires that the neural network is configured to receive images. Pet. 35 (citing Ex. 1002 ¶¶ 47–51, 118; Exs. 1017, 1023, 1024, 1026). Petitioner’s argument that combining Krishnan and Lee “would merely amount to applying known work from the field . . . to yield predictable results” is not persuasive because the Petition ties this reasoning to modifying Krishnan with Lee’s view-category-specific assessment parameters, not modifying Krishnan’s quality assessment neural network to receive images instead of extracted features.

“We need not resolve the above-identified dispute, because a different aspect of “beforehand locally stored” is determinative. Read in context, “beforehand locally stored” in both limitations 1(a)(2) and 12(a) refer back to the “preliminary search” action recited in limitation 1(a)(1) and in limitation 12(a) itself, respectively. Thus, we construe “beforehand locally stored” to mean that the selection pages must already be stored within the communication device when the user begins the preliminary search, regardless of whether it was the user or an automated process that downloaded the selection pages to the communication device.

Petitioner does not adequately address the issue of sufficient spacing on Nagasawa’s case body 1, which includes two back-to-back mounted displays 4 and 8 (Figure 1A), to include two additional cameras, one facing inward and the other facing outward, particularly as one side of case body 1 is used for gaming (Fig. 1B, Ex. 1007, 3:53–65).

“identifies and refers to a valid region of the integrated circuit memory device as having a three-dimensional boundary delimited by phase ranges in command/address signals, data signals, and sampling signals. Nowhere does the ’835 patent specification indicate a valid region of the integrated circuit device as a whole can be represented by values for less than three parameters x, y, and z, all together, e.g., the command signals, the data signals, and the sampling signals. Also, the ’835 patent describes that the purpose of determining the boundaries of a valid region is to configure an optimal operating point for the integrated circuit device. Ex. 1001, 5:48–51. We have also considered other language in the claims. Each of independent claims 1 and 7 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operation range.” Ex. 1001, 6:56–7:4, 7:18–34. Each of independent claims 12, 20, and 23 requires adjustment of the phase of all three command signals, data signals, and sampling signals, to determine the “valid operating range.” Ex. 1001, 7:46–60, 8:28–44, 8:62–10:4. Based on the foregoing, the specification informs us that “valid operation range” is a three-dimensional range. We recognize that the specification does not expressly exclude a two-dimensional range or multiple two-dimensional ranges from being a “valid operation range” of the integrated circuit device.

“Level of Ordinary Skill in the Art Citing testimony from Dr. Baker, Petitioner asserts a person of ordinary skill in the art (hereinafter “POSITA”) “would have had a bachelor’s degree in electrical engineering, computer engineering, or the equivalent, and two to three years of experience designing high speed computer memory devices.” Pet. 4 (citing Ex. 1002 ¶¶ 31–35). Patent Owner’s expert, Mr. Lee, testifies: “I agree with Petitioner that [Petitioner’s statement of the level of ordinary skill] would be the minimum qualifications for a POSITA.” Ex. 2001 ¶ 35. On this record, we adopt Petitioner’s statement of the level of ordinary skill in the art, i.e., that a POSITA “would have had a bachelor’s degree in electrical engineering, computer engineering, or the equivalent, and two to three years of experience designing high speed computer memory devices.” Ex. 1002 ¶ 34. The stated level is supported by the testimony of Dr. Baker and not disputed by Patent Owner. Further, it appears consistent with what is reflected by the content of the applied prior art. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (the applied prior art may reflect an appropriate level of skill). C.” slip op. at 12

“Petitioner still has not made a sufficient showing for limitation [1.4.a]. That is because Petitioner has, at best, identified only two 2-parameter valid operation ranges, i.e., an operation range involving just command and sampling signals, and an operation range involving data and sampling signals. Pet. 29–34. This does not satisfy “valid operation range” as we have construed above in Section III.C. Specifically, we determined that “valid operation range” is a three-dimensional range including a boundary for each of three underlying parameters which, for example, may be the phases of the command signals, the data signals, and the sampling signals. Nowhere has Petitioner identified or explained how Johnson discloses a valid operation range that is a function of three parameters together, e.g., the respective phases of command signals, data signals, and sampling signals. In addition to the foregoing, Petitioner’s reasoning for adjusting the phase of clock signals DCLK, which Petitioner regards as sampling signals, to synchronize with the phase of data signals on the DQ data bus is unpersuasive, because Johnson, as Petitioner has recognized, already adjusts the phase of data signals on the DQ data bus to synchronize with clock signals DCLK. Pet. 32 (citing Ex. 1002 ¶ 136; Ex. 1004, 4:55–59, 6:46–48, 7:25–31, 7:36–42). The proposed adjustment is redundant and serves little, if any purpose. Petitioner has not proposed to stop adjusting the data signals relative to DCLK. Nor has Petitioner articulated a reason to do the adjustment in both directions, i.e., adjusting the data signals relative to the sampling signals and adjusting the sampling signals relative to the data signals. We have also determined above, in discussing limitation [1.3], that Petitioner has not sufficiently shown that Johnson’s CCLK signal is a sampling signal. Further, we agree with Patent Owner (Prelim. Resp. 24) that neither delay 55 nor delay lock loop 41 in Johnson’s Figure 4 is used for systematic calibration of any signal or in a signal calibration process. We find that the mere presence of a delay element in a signal path does not reasonably suggest systematic calibration. For the foregoing reasons, Petitioner has not sufficiently shown that” slip op. at 31

“1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits. See Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 11 at 6 (PTAB Mar. 20, 2020) (precedential) (“Fintiv factors”). “These factors relate to whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” Id. In evaluating the Fintiv factors, we take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review,” recognizing that “there is some overlap among these factors” and that “[s]ome facts may be relevant to more than one factor.” Id.” slip op. at 9

“whether to institute an inter partes review. Applying the standard set forth in 35 U.S.C. § 314(a), we may not institute an inter partes review (also “IPR”) unless the information presented in the petition “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” However, institution of inter partes review is discretionary. See Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he PTO is permitted, but never compelled, to institute an IPR proceeding.”).

“Thus, although Petitioner contends that Njølstad implements a dynamically changeable frequency for each domain wherein a local “rate requirement can dynamically be configured” such that “the locally generated clock rate is just high enough to perform the actual processing task” at that rate (Pet. 31 (citing Ex. 1009 § IV.D)), such teaching merely supports Petitioner’s contention that the frequency is dynamically changeable at the local level (id.). However, as Patent Owner points out, such showing is not a compelling disclosure of the frequency generation being independent of the frequencies of the other domains, as required by the challenged claims. Prelim. Resp. 28–34. For the foregoing reasons, we conclude that Petitioner has not presented compelling merits that Njølstad teaches “the frequency being dynamically changeable independently of the frequencies of the clock signals generated for others of the plurality of domains” as recited in claim 1 and similarly recited in claim 8.” slip op. at 25

“However, Patent Owner argues that Iyer published after the invention to the ’443 patent was actually reduced to practice. Prelim. Resp. 27–28. In particular, Patent Owner provides evidentiary testimonies of Dr. Kaeli (Ex. 2001) and Mr. Albonesi (Ex. 2003) to support its contends the ’443 patent incorporates by reference a paper authored by the inventors and published in February 2002 (Ex. 2005), which demonstrates conception by providing a full written description of the claimed invention. Prelim. Resp. 6–16. According to Patent Owner, a simulation described in the paper embodied the invention in a tangible form, wherein the simulation described in the paper showed that the invention worked for its intended purpose. Id. at 16–19 (citing Exs. 2001, 2003, 2005). Similarly, Patent Owner contends that the application from which Soerensen issued was filed on August 29, 2002, which is after the invention date of the ’443 patent. Prelim. Resp. 35. According to Patent Owner, while Soerensen claims priority to the Soerensen Provisional Application (Ex. 1022), the passages from Soerensen relied on in the Petition are not entitled to the benefit of the filing date of the Soerensen Provisional Application because the subject matter was not disclosed in the manner provided by 35 U.S.C. § 112. Id. We recognize potential merits to Patent Owner’s position. That is, we do not find compelling Petitioner’s contention that the challenged claims would have been obvious Iyer or Soerensen.” slip op. at 31
