“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.

“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.

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.

PAR Pharm., 773 F.3d at 1195. Accordingly, we do not credit Dr. Hansen’s testimony that implicates the doctrine of inherency because it not supported by evidence of record.” slip op. at 17

“In the Petition, AT&T contends that “the Board does not need to expressly construe any [claim] terms to resolve the arguments presented herein” because the asserted prior art “discloses all limitations under any plausible construction.” Pet. 14 (citing Ex. 1002 (Declaration of Dr. Christopher Hansen) ¶ 456).

“We agree with Autoscribe’s argument that PayPal Express Checkout does not teach the “providing” steps of independent claim 1 and 25 and the “receiving” step of independent claim 15 for two reasons. First, as we explain in our claim construction analysis above, we decline to adopt M&A Ventures’s proposed construction of the “providing” and “receiving” steps as being limited temporally such that not providing the data token to the payer only occurs “during execution of the token retrieval function.” Instead, we construe the “providing” and “receiving” steps in accordance with their plain and ordinary meanings, which includes giving the negative limitation recited therein (i.e., not providing the data token to the payer) patentable weight, without limiting the occurrence of this negative limitation during execution of the token retrieval function. See supra Section II.A.1. With this construction in mind, step 4 of the PayPal Express Checkout flow run in the sandbox environment plainly sends the Payer ID, which M&A Ventures maps to the claimed “data token,” to the buyer. Ex. 1006, 17, 25–26; see also Pet. 64 (arguing PayPal’s Payer ID teaches the “non-sensitive electronic data token” (emphasis omitted)), 67 (arguing the same). Because PayPal sends the Payer ID to the buyer during the PayPal Express Checkout flow, PayPal provides the data token to the payer and, therefore, violates the negative limitation required by the “providing” and “receiving” steps.” slip op. at 31

“In addition to the above information, it would be beneficial for the macro eNB to send a measurement gap configuration (as dis-cussed in 3GPP TS 36.331 V1.1.2.0) allocated for the UE to the Small cell eNB so that the Small cell eNB could take measure-ment gaps into consideration when scheduling resources to the UE. For example, the small cell eNB could avoid scheduling the UE during measurement gaps because the UE cannot transmit or receive any signal to/from the Small cell during the measurement gaps. Ex. 1001, 6:41–49 (emphasis added). We particularly note the literal written description support (in italics) in the ’559 Patent that mirrors the claim [1e] language: “so that the Small cell eNB could take measurement gaps into consideration when scheduling resources to the UE.” Id. at 6:45–46 (emphasis added). Moreover, as noted above, Figure 5 of the ’559 Patent depicts flow chart 500. Prelim. Resp. 3–4 (citing Ex. 1001, 6:65–7:3).

“Patent Owner responds that “a person with the 3-year experience proposed by Petitioner would not have the intimate knowledge of the existing standardized cellular system” required to understand “how a proposed change would impact the rest of the system.” Prelim. Resp. 7. But Patent Owner also states that engineers participating in the development of the relevant cellular specifications “would not be expected to be familiar with all relevant aspects of the specifications” given their length and complexity. Id. at 7–8. For purposes of this Decision, we adopt Petitioner’s proposed level of skill, as articulated above, because we are satisfied that it generally comports with the level of skill necessary to understand and implement the teachings of the ’883 patent and the asserted prior art. To the extent Patent Owner disagrees (see Prelim. Resp. 6–8), it fails to sufficiently explain its contrary position by, for example, providing its own proposed level of skill.” slip op. at 9

“(step 406) discloses the claimed “second request” (Pet. 44–45),9 but Petitioner fails to show that this message discloses a request. See Prelim. Resp. 46–48. Han explains that the dual connection setup response in step 406 is a “dual connection setup request acknowledge (ACK)” message sent in response to “dual connection setup request” received in step 404. Ex. 1007 ¶¶ 40–42; accord Pet. 42–44. An acknowledgement is not a request, and Petitioner fails to sufficiently support its contention to the contrary (see Pet. 44–45). According to Petitioner, the acknowledgement message is “a request to change a data path” because the data path is “change[d] . . . based on this message” (id. at 45 (citing Ex. 1007 ¶¶ 42–47; Ex. 1003 ¶ 202)); however, this is faulty reasoning. At most, Petitioner’s argument shows that the acknowledgement is a message “to change a data 9 We note that this is the same message relied upon by Petitioner to teach the claimed “accept message” recited earlier in claim 1. Compare Pet. 44– 45, with id. at 43–44. We need not (and do not) decide whether Petitioner has sufficiently shown that this message discloses two separate claim elements. path,” not that it is a request to do so. In other words, even if Han’s acknowledgement message (in step 406) is a condition precedent to changing the data path, this does not make the message a “request.” Although Dr. Mahon agrees with Petitioner, his analysis mirrors Petitioner’s arguments and suffers from the same deficiencies.
