“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.

“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

“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.

“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)).

Essentially, Figures 7A–7C represent a disclosed algorithm used with a CPU of a microprocessor with memory for implementing the algorithm to control the supply of current from a power supply to a coil surrounding a moveable magnet. See, e.g., Ex. 1001, Fig. 6; supra Section.

“Here, claim 1 requires the functionality of, for example, “selecting one of the plurality of views for display on the computer system in response to the detected current computer system configuration.” Ex. 1001, 71:34–36. As in Arendi and DSS, this functionality plays a major role in the subject matter claimed; this selection as at the heart of the ’818 patent. See, e.g., Ex. 1001, 2:49–62 (explaining that patent is directed to providing different views). We also determine that the limitation is not “unusually simple.” The cited art understood that display orientation could be modified based on a change in configuration (Pröll) and understood that a view could be selected based on a user’s active choice (the user shaking the device as in Martinez6), but the cited art did not recognize selecting a view based on a change of configuration.
