“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. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

“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. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004) (citing In re 1 US 2013/0108922 A1, published May 2, 2013 (Ex. 1004, “Shinozaki”). 2 G. Khatibi, Temperature Dependent Elastic and Thermal Properties of Thin Copper Foils, Copper; Proceedings of the International Conference Copper ’06 (2006) (Ex. 1006, “Khatibi”). 3 Korean Patent Pub.

“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. Teleflex Inc., 550 U.S. 398, 421 (2007) (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”).

“But Bruckman’s “trunk link” (or LAG as argued by Petitioner) is explicitly disclosed as a link to a core network, not as the links (or traces 34 on backplane 26) to subsidiary modules 24, as argued by Petitioner: “In network access systems, for example, a backplane may be used to connect a main module, having a trunk link to a core network, to a number of subsidiary modules, such as line cards, with ports serving network users. Ex. 1007, 1:25–30 (emphasis added); see id. at 1:61–2:4 (“The master module comprises a switch, which is typically used for linking the subsidiary modules via the connection lines to a network trunk.” (emphases added)); Dec. 25. Bruckman also explicitly discloses that “[a]t any given time, a number of the connection lines [between main module 22 and subsidiary modules 24, i.e., traces 34] are likely to be idle” (Ex. 1007, 2:2–4), which is contrary to a purpose of a LAG (see Ex. 1001, 2:10–16 (“The [LAG] forwarding entity usually attempts to distribute the load evenly over each physical output port of the aggregated logical link.” (emphasis added))). See Dec. 25–28. Thus, in the Decision, we found neither Petitioner nor its declarant had explained sufficiently, let alone with particularity, why the skilled artisan, but for hindsight, would have understood Bruckman to teach the Physical/Logical Link Limitations, of which the physical links are subject to the Designating Limitations, as recited, for example, in claim 1. Indeed, we were not persuaded by Petitioner’s arguments in its Petition as to the Physical/Logical Link Limitations, and having reviewed the Request, remain unpersuaded. See KSR Int’l Co. v.
