“In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26.

“II. STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may be determined “if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors.” Arnold Partnership v.

“For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

“Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v.

“We are not persuaded, on this record, that Petitioner adequately establishes that Khatibi discloses a CTE in the claimed range of 16 to 22 µm/(m·°C.). Petitioner’s argument that Khatibi’s reported values meet this claim limitation are based solely on Dr. Randall’s testimony that Khatibi’s measurement method would produce results that would not significantly differ from results determined using the claimed method. See Pet. 16–18 (citing Ex. 1003 ¶¶ 56–60). Dr. Randall’s testimony, however, is largely conclusory and unsupported by adequate explanation and/or objective evidence. For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements.

“second surfaces of the electrolytic copper foil ranges from 3 to 92.” Ex. 1001, 13:62–63. Petitioner contends that “Kim teaches that the electrolytic copper foil (e.g., untreated or treated copper foil) having Rz less than 2 µm is advantageous toward battery efficiency and performance,” and, similarly, Griesi describes the use of untreated electrolytic copper foil with an Rz value less than 2 µm in printed circuit boards that are compatible with secondary batteries. Pet. 58–59 (citing Ex. 1012, claim 2, ¶¶ 13, 25, 27; Ex. 1003 ¶ 157). In particular, Petitioner notes that Griesi’s Figure 3.16 describes an “Rz value of 1.2 µm.” Id. at 59 (citing Ex. 1015, 53–54; Ex. 1003 ¶ 158). Petitioner asserts that “Dr. Randall explains that a POSITA would have also recognized another surface roughness-related parameter, Rpc, in Griesi as a potentially useful parameter that can be optimized to further enhance uniformity or generally improve Kim’s copper foil surface, for example, to prevent wrinkles or achieve other advantageous effects.” Id. (citing Ex. 1003 ¶ 159). Although Dr. Randall demonstrates that Griesi’s Pc (or Rpc) value is 19.2 over a 4 mm sampling length (Ex. 1003 ¶ 155), Petitioner does not contend that Griesi addresses this value, or indicates any benefit that might be derived from its use. Instead, Griesi’s Pc value appears to be an incidental finding, which is not discussed or analyzed in the reference. See incidental, unexamined finding would lead a POSITA to import Griesi’s Pc value into Kim’s copper foil, absent a hindsight desire to reconstruct the claimed invention. As such, Petitioner’s arguments with respect to Kim and Griesi are not persuasive. See Cheese Sys. Inc. v. Tetra Pak Cheese and Powder Sys., Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013) (“Obviousness cannot be based on the hindsight combination of components selectively culled from the prior art to fit the parameters of the patented invention.” (internal quotations marks omitted)).

“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. However, that is why we construe the claims to determine what, if anything, may be required despite a lack of express recitation in the claims.” slip op. at 17
- Skill levelSkill level petitioner adoptedDecided for petitioner
“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

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.

“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
