      “review. 35 U.S.C. § 314(b) (2018); 37 C.F.R. § 42.4(a) (2024). An inter partes review may not be instituted “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.” 35 U.S.C. § 314(a). Upon consideration of the Petition and the evidence of record, we conclude that the information demonstrates a reasonable likelihood that Petitioner would prevail in showing the unpatentability of at least one of the challenged claims. Accordingly, we institute an inter partes review as to the challenged claims of the ’047 Patent.” slip op. at 2

      “Petitioner contends that a person having ordinary skill in the art at the time of the invention (“POSITA”) “would be a regular consumer/shopper with a rudimentary knowledge of the use of magnetic clips and a basic understanding of clip construction.” Pet. 13. We find, for purposes of this Decision, that the ’047 Patent and the cited prior art references reflect the appropriate level of skill at the time of the claimed invention and that the level of skill reflected in these references and in the ’047 Patent is consistent with the definition of a person of ordinary skill in the art proposed by Petitioner.

      “The ’047 Patent discloses that in addition to being separate straps, the rear strap and the front strap “can be formed from a single piece of material.” Ex. 1001, 3:40–44, 5:24–32, 10: 18–25. In particular, Figures 5A–5B of the ’047 Patent illustrate rear strap 510 and front strap 520 as being “formed from a single piece of material that is folded approximately in half where a first half can be the rear strap 510 and a second half can be the front strap 520.” Id. at 10:18–21, Figs. 5A–5B. Indeed, Patent Owner acknowledges “[i]t should be noted that forming the first and second straps from a single piece of material is well within the scope of the claimed invention.” Ex. 1007, 5 (citing the ’047 Patent at 3:37–44). Moreover, we note the positions taken by the parties are consistent with the fact that claim 13, which depends from claim 1, recites “wherein the first strap and the second strap are formed from a single folded strap.” Ex. 1001, 14:47–48. We, therefore, adopt Petitioner’s construction of “the second strap joined to the first strap” to include “a single piece of material.”” slip op. at 12

      “The ’047 Patent discloses that the hook is used to attach the hat holder to another object. Ex. 1001, 8:31–33. In reference to Figures 3A–3C, the ’047 Patent discloses that “the hook 340 is formed from a strap of flexible material. The flexible material can be, for example, nylon, leather or leatherette. The hook 340 can be formed from the same material as the front or rear straps 310 and 320, respectively.” Id. at 8:26–31, Figs. 3A–3C; see also id. at 6:58–7:3. This disclosure is indicative that the term “hook” can be a strap in contrast to a structure that is typically regarded as being a hook, as shown in Figures 1A–1C, 2A–2C, 4A–4B, 6A–6B, 7, 8 of the ’047 Patent. Additionally, we note that consistent with the above disclosure, claim 10, which depends from claim 1, recites “wherein the hook is [a] flexible strap having a closure.” Ex. 1001, 14:41–42. We, therefore, adopt Petitioner’s construction of a “hook” to include “structure that serves to attach the hat holder to another object.”” slip op. at 13

      “Petitioner contends that a person of ordinary skill in the art (“POSITA”) at the time of the invention of the ’223 patent “would have a degree in Mechanical Engineering and at least three years’ experience in vehicle suspension technology, or a Master’s degree in Mechanical Engineering with a concentration in design of vehicle suspension technology and/or shock absorbers.” Pet. 5–6, n.1. Patent Owner does not contest Petitioner’s proposed level of ordinary skill in the art. See PO Resp. Based on the complete record, we adopt Petitioner’s proposal as reasonable and consistent with the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “As Petitioner discerns, claim 1 does not recite “dampening only at the end portion of a compression stroke.” Rather, claim 1 expressly requires “a fluid flow path formed in the bottom out cup for providing fluid communication from the cup to the compression portion of the chamber during a compression stroke of the damper[.]” Ex. 1001, 7:44–47 (emphasis added). In this way, claim 1 contemplates that the bottom out cup operates “during a compression stroke of the damper,” rather than only at the end portion of a compression stroke or only near an end of a compression stroke. Similarly, independent claims 11 and 19 do not require that the bottom out cup provide damping only at the end or near the end of a compression stroke. See Ex. 1001, 8:8–23, 8:61–9:5. Claim 11 recites “a bottom out cup in fluid communication with the damper chamber” and “an adjustable fluid flow path formed in the cup, the flow path providing fluid communication between the cup and the primary compression chamber in a compression stroke of the damper.” Id. (emphasis added). Claim 19 also recites “in a compression stroke of the damper” and does not limit damping to the end, or near the end of a compression stroke. See id. at 8:61–9:5 (“in to the compression chamber at a first rate with the valve in a first position and at a second rate with the valve in a second position where the first rate is greater than the second rate and the valve includes an adjuster accessible from an exterior of the shock absorber.”) (emphasis added). The ’223 patent as a whole also does not describe the bottom out cup as damping or providing dampening only at the end or near the end of the compression stroke, but more broadly as during the compression stroke. With reference to Figure 3A, the ’223 patent discloses that bottom out piston 250 enters “the bottom out cup 275 during a compression stroke of the shock absorber.” Ex. 1001, 3:38–50 (emphasis added). Additionally, we observe that the ’223 patent discloses “[a]s the piston completely engages the cup 275, dampening is increased.” Id. at 3:64–65 (emphasis added). We understand this to mean that bottom out dampening occurs at the end of the compression stroke, but may also occur “during” the compression stroke and “increase” as the piston completely engages the bottom out cup.” slip op. at 16

[and] bottom out cup 260, 460 (pink) is formed at the end of compression portion 26.4 (light red) and provides additional damping to reduce bottoming out[.]” Ex. 1019 ¶ 58 (citing Ex. 1010, Abstract, annotated Fig. 12A, 1:15–33, 9:33–48; Ex. 1002 ¶¶ 179– 180, 188–190; Pet. 108–110). As discussed above, internal shock absorber 400 contains cup-shaped compression volume 460.4 that provides additional damping after the initial portion of the compression stroke. See Ex. 1010, 7:49–51, 7:55–56, 7:62–67, 9:20–24. Gartner further discloses these features as accommodating or protecting from bottoming out. See id. code (57). Patent Owner’s position and Dr. Slocum’s testimony otherwise, requires Gartner to expressly invoke the term “bottom out cup” instead of compression volume. See Ex. 2010 ¶¶ 104–106. We disagree that is necessary. The elements must be arranged as required by the claim, but this is not an ipsissimis verbis test, i.e., identity of terminology is not required.

We find that Gartner discloses a “cup-shaped feature configured for providing dampening at the end of a compression stroke.” Gartner discloses that internal shock absorber 400 provides damping after the initial portion of the stroke and as compression continues, compression volume 460.4 reduces as part of that damping.

      “Id. code (57) (emphases added). Though Gartner does not explicitly employ the term “bottom out cup,” it is not lost upon us that the internal shock absorber, e.g., shock absorber 400, functions during/in a compression stroke (e.g., after the initial portion of the compression stroke), to provide dampening while protecting from bottoming out.

      “We disagree with Patent Owner. It is true that Oyobe focuses on alerting a vehicle user to a low state of charge by raising a physical indicator on the exterior of the vehicle (i.e., the “informing apparatus 102) when the battery is low. Ex. 1005 ¶ 40. Oyobe explains: even in such a case where the vehicle user exit from the vehicle without checking the SOC of main battery B on the console panel, informing apparatus 102 disposed at a location where it can easily be seen outside the vehicle by the vehicle user allows the vehicle user to easily recognize the necessity of charging main battery B. Id. However, Oyobe’s focus on raising a physical indicator on the vehicle as a reminder does not detract from Oyobe’s unambiguous disclosure that its vehicle also includes position detecting apparatus 108 that uses wireless communication to “sense that the vehicle is parked at the location where charging equipment is installed.” Id. ¶ 142. Oyobe’s ability to sense whether a vehicle is parked next to a charger allows Oyobe’s system to remind the user to charge the battery by raising low battery indicator 102 while the vehicle is located next to a charger but not “where charging cannot be performed.” Id. ¶¶ 143–145. Accordingly, regardless of the reason that Oyobe provides for including its vehicle position detecting apparatus, Oyobe undeniably describes a vehicle sensor that can provide “information indicative of a presence of an electric vehicle in a parking space” near a charging station. And, we find that Petitioner has sufficiently explained why an ordinarily skilled artisan would have been motivated to use Oyobe’s sensor in Ferro’s electric vehicle to “advantageously allows a user to instruct charging without exiting the vehicle and physically interacting with a charging station.” Pet. 11–12 (citing Ex. 1003 ¶¶ 150–152).” slip op. at 20

      “Third, Patent Owner argues that Petitioner violates Rule 42.6(a)(3) by improperly incorporating arguments from Mr. Andrews’s Declaration into the Petition to establish that Oyobe teaches sensing the presence of a vehicle in a “parking space” as recited in limitation 1e. Prelim. Resp. 42–43 (citing Pet. 19–20 (citing Ex. 1003 ¶¶ 178–181)). Patent Owner contends that Mr. Andrews’s citation of four references that are not expressly cited in the Petition, Exhibits 1018, 1053, 1057, and 1059, implicitly demonstrates that the Petition incorporates arguments by reference. Id. Not only do we find Petitioner’s reliance on Mr. Andrews’s testimony to be persuasive, but we also find that Mr. Andrews’s citations to Exhibits 1018, 1053, 1057, and 1059 provide strong support for his testimony that an ordinarily skilled artisan would understand that Oyobe teaches that its vehicle is in a parking space when Oyobe’s apparatus 108 detects that “the vehicle is parked” near charging equipment. Far from improperly incorporating arguments by reference, we find Mr. Andrews’s citation to objective evidence to support his opinions on how an ordinarily skilled artisan would read Oyobe’s disclosure to be preferred and highly persuasive.” slip op. at 21

      “Petitioner also focuses on Hanafusa’s teaching that all known methods can be used to make a rough surface low-profile, and Dobashi’s teaching that RSm can be used as an indicator for judgment of the surface, to support its contention that a POSITA would have been motivated to apply Dobashi’s RSm to further achieve Hanafusa’s purpose, without explaining how and why that would be the case. 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 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 also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66– 3:1.

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.

      “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. 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). to little weight.

Mova Pharm. Corp., 225 F.3d 1306, 1311 (Fed.

      “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)). Thus, we are not persuaded, on this record, that the combined disclosures of Kim and Griesi teach all of the elements of limitation [1g].” slip op. at 23

      “Based on the record before us, Petitioner does not set forth sufficient argument and evidence to demonstrate that the combined teachings of Doshi, Guichard, and Ashwood Smith teach or suggest “digital logic . . . configured to determine a probability of concurrent failure of said working entity and said protection entity,” as recited in claim 14. Accordingly, there is not a reasonable likelihood that Petitioner would prevail in showing that the subject matter of independent claim 14 would have been obvious over Doshi, Guichard, and Ashwood Smith. Due to the dependency of claims 15 and 16 from claim 14, and for the same reasons as those explained above addressing claim 1, based on the record before us Petitioner does not set forth sufficient argument and evidence to demonstrate that the combination of Doshi, Guichard, and Ashwood Smith teaches or suggests the limitations of claims 15 and 16.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “We agree with Patent Owner’s arguments. We find that Petitioner does not show sufficiently that Ashwood Smith discloses, teaches, or suggests “digital logic . . . configured to determine a probability of concurrent failure of a working entity and a protection entity,” as required by claim 14. Petitioner implicitly construes “digital logic . . . configured to determine a probability of concurrent failure of said working entity and said protection entity” to require “calculat[ing] the probability of concurrent failure of the paths.” Pet. 77; see also id. (“calculating such probability for two paths”), 78 (also implicitly construing “digital logic . . . configured to determine an entity cost of said plurality of transport entity descriptors” to require “cost calculation”). We agree with Petitioner’s implicit construction because it is consistent with the claim language and the ’821 Patent Specification which discloses a simultaneous failure probability (SFP) function (Eq. 1) and SFP values calculated by a concurrent failure probability matrix. See Ex. 1001, 3:44–47, 6:5–11, 6:39–40. Similar to Doshi’s description of the probability of failure in terms of “very insignificant” (see Ex. 1005 ¶ 40), Petitioner’s cited disclosures of Ashwood Smith describe the probability of failure at a common point in terms of “fairly low” (see Ex. 1037, 3:21–23) “highly unlikely” (see Ex. 1037, 10:32), and “below a certain level” (see Ex. 1037, 11:7–8). Although Petitioner asserts that Ashwood Smith’s method determines the probability of failure at a common point between two paths (see Pet. 67), the teachings of Ashwood Smith cited by Petitioner do not support a finding that Ashwood Smith discloses, teaches, or suggests “digital logic . . . configured to determine the probability of concurrent failure,” as implicitly construed by Petitioner to require calculating a probability of concurrent failure of a working entity and a protection entity. Petitioner also cites Ashwood Smith’s disclosure suggesting a possible refinement to the disclosed method that would take into account the actual probability of failure at a common point shared by two or more working paths. See Ex. 1037, 10:21–24. Petitioner, however, does not direct us to any disclosure in Ashwood of digital logic configured to determine or calculate the probability of failure at a common point. See Pet. 66–69, 74–78. Instead, Petitioner overlooks Ashwood Smith’s disclosure that the probability of failure at a common point is allocated (i.e., distributed, assigned, given out) by the data transport network operator. See Ex. 1037, 11:4–6. This allocation of failure probability by the data transport operator is similar to the ’821 Patent Specification’s disclosure that “[s]pan failure probabilities may be assigned, for example, manually by a network operator based on network knowledge” and “[n]ode failure probabilities may be configured by the operator, typically based on vendor-provided mean time between failure (MTBF) parameters, and on infrastructure failure probability, for example, power failure probability.” Ex. 1001, 6:20–23, 6:29–33. We also give little weight to Petitioner’s witness Dr. Min’s testimony (Ex. 1003 ¶¶ 234–237) that Ashwood Smith teaches determining a probability of concurrent failure of two paths because, for the same reasons, it is not supported by an underlying factual basis. See 37 C.F.R. § 42.65(a).” slip op. at 22

      “IPR2023–00402, we find that Doshi does not disclose, teach, or suggest “digital logic . . . configured to determine a probability of concurrent failure of said working entity and said protection entity,” as required by claim 14. Although Doshi discloses selecting a subset of path pairs based on cost (see Ex. 1005 ¶ 144, Fig. 11), and that disjoint path pairs may have very insignificant probability of failure, Petitioner does not direct us to where Doshi discloses, teaches, or suggests “digital logic . . . configured determine the probability of concurrent failure of the primary path and the restoration path.” See Pet. 67, 74–76. We also give little weight to Petitioner’s witness Dr. Min’s testimony (Ex. 1003 ¶ 255) that determining path disjointedness corresponds to determining a probability of concurrent failure is entitled to little weight because, for the same reasons, it is not supported by an underlying factual basis. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). For example, Petitioner does not provide a factual basis for equating a determination of path disjointedness (e.g., strictly disjoint, partially disjoint) with a determination of the probability of concurrent failure of the primary and restoration path. We also give little weight to Dr. Min’s testimony (Ex. 1003 ¶ 258) that Doshi’s disclosure of selection logic configured to perform the method of Figure 11 teaches logic configured to determine probability of concurrent failure of said working entity and said protection entity because it also is not supported by an underlying factual basis.
