“construction principles, and does not revise or ignore the explicit language of the claims.”). In that vein, “[p]roper claim construction . . . demands interpretation of the entire claim in context, not a single element in isolation.” Hockerson–Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed.Cir.1999); accord Phillips, 415 F.3d at 1314 (“[T]he context in which a term is used in the asserted claim can be highly instructive.”). Patent Owner’s interpretation that “the current version” requires two current versions — one locally stored current version and a corresponding remotely stored current version — asks us to improperly adopt a claim construction which ignores explicit claim language and context in order to read unrecited features into the claim. The limitation in question, more fully and in better context, recites “storing the selected previous version . . . as the current version on the local storage location.” Ex. 1001, 9:24–26 (emphasis added). The express language shows that the claim is specifically directed to the current version on the local storage location and not any possible remote current version. As such, even if there were a “current version on the remote storage location” which corresponds to and is kept in parity with the current version on the local storage location, i.e., a backup copy of the locally stored current version, the claim does not recite that feature, establishing that it does not require that feature. Further, as to the context of the claim, the term in question is part of a recited method of restoring a file to a previous version of the file on a local computational machine, rather than a method for maintaining parity of remotely stored backup files during that restoration process. See id. at 8:63–9:28. As such, the explicitly recited claim language and the context of the claim do not support reading an unrecited remote backup feature into the claim.” slip op. at 11

“been obvious to use the “Download” feature described by Sweat to replace a corrupted or otherwise compromised file, thus meeting “storing the selected previous version . . . as the current version on the local storage location.” Pet. 60–62. First, regarding the technical operation of Sweat’s download function, Petitioner explains that a user “download[s] a version of [a] file from the server 106 to the local computer 104” and selects a local “target location to save the selected file.” Id. at 61 (citing Ex. 1006, 10:58–63). Sweat’s download function “[c]opies the file or folder to the user’s local computer” and can “overwrite files that exist on the user’s local computer, as desired.” Ex. 1006, 5:49–55. From those disclosures, Petitioner asserts it would have been obvious to use Sweat’s download function “to restore a previous version of a file by copying the file to the user’s local computer and overwriting the current version of the file on the user’s local computer, so as to save the restored file as the new current version of that file.” Pet. 62 (citing Ex. 1004 ¶¶ 125– 126). Petitioner explains that the download function would be used in such a manner where a user “desire[s] to restore a previous version of the file to replace the current version for example, in the case where the newest version of the file has become corrupted or where desired data has been deleted from” slip op. at 21

“We agree with Petitioner. Sweat’s description of its “Viewing Files” feature explains that “a user must install the appropriate viewer to open and view drawing files.” Ex. 1006, 23:38–41. Sweat lists examples of such viewers including software applications such as Volo™ View Express. Id. at 23:45–46, 23:63–67. While Sweat does not list a CAD file creating application in its exemplary list of viewers in that “Viewing Files” section (see id. at 23:38–24:35), elsewhere, Sweat states that a CAD application, e.g., “AutoCAD®,” is “drawing/viewing software utilized by the viewer” (id. at 23:29–33). Furthermore, Petitioner’s declarant offers undisputed testimony that AutoCAD is software for creating CAD drawing files and can also be used to view those created CAD drawing files. Ex. 1024 ¶ 39 (citing Ex. 1029, 19–23, 541–542). On that evidence, we agree a POSITA would understand that Sweat describes using a viewer to preview previous versions of CAD drawing files and that Sweat also describes AutoCAD (which creates CAD drawing files) can be used as a viewer. In light of that understanding, we agree it would have been obvious to use AutoCAD, i.e., “an application that created the file,” to preview previous versions of that file. Pet. 62–63. We also agree that it would have been rational to do so because the same already locally available software application which created the file could then be used to view the file. Id.; see Ex. 1004 ¶ 128. Owner dismisses Petitioner’s obviousness argument as “irrelevant,” and, instead, argues that Sweat does not disclose the claimed features. PO Sur- Reply 16–17; see PO Resp. 39–40. In particular, Patent Owner argues Sweat “discloses the use of specialized viewing software to view the related file” and emphasizes that “CAD software is clearly not being used in Sweat’s ‘View in Window’ functionality” PO Resp. 39–40 (citing Ex. 1006, 23:39–51); PO Sur-Reply 17. While it may be the case that Sweat does not outright disclose the features recited in the claim, those arguments do not show fault in Petitioner’s case that the claimed features would have been obvious. See CRFD Rsch., Inc. v. Matal, 876 F.3d 1330, 1345 (Fed. Cir. 2017) (“Even if a reference’s teachings are insufficient to find anticipation, that same reference’s teachings may be used to find obviousness.”); Nike, Inc. v. Adidas AG, 812 F.3d 1326, 1335 (Fed.

“B. Level of Ordinary Skill in the Art As noted above, resolving the question of obviousness requires determination of the level of ordinary skill in the art. Graham, 383 U.S. at 17–18. Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner. The absence of such assessment calls into question the fundamental adequacy of Petitioner in carrying its burden to show a reasonable likelihood of success of unpatentability of the challenged claims that necessarily must take into account the level of ordinary skill in the art.” slip op. at 10

“Nike and its expert mischaracterize Hong. After close review of the opinions of both parties’ experts, we credit the opinion of lululemon’s expert as more consistent with Hong’s disclosure than that of Nike’s expert.

That disclosure by Hong of “knitting directly” the 3D shape clearly suggests it is formed as part of Hong’s flat-knitting process, and not as part of some post-knit seaming process. Hong’s additional disclosure of “diminish[ing] the labour cost inherent to the use of two-dimensional fabrics” also cuts against Nike’s notion of an additional step of “forming that two-dimensional pattern piece into a three-dimensional structure” following the flat knitting step.

We also find that one skilled in the art would have a reasonable expectation of succeeding in forming an article of footwear having such a domed, three-dimensional structure as a result of combining the teachings of Dua, Hong, and Lockwood.

We further agree with Petitioner that to the extent “transaction data” is for the purpose of conducting banking transactions, Cho’s account data of a credit card number and expiration date can perform that purpose.

“Owner’s challenge to Petitioner’s Fukui-based grounds is whether, in Fukui, a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette.11 We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) forming “one body” (see, e.g., id. at 8:2–3). Further still, as described and shown in Fukui (e.g., Figure 5), conversion module 20 is structured to operate via a singular multicore optical connector 16 from which optical fibers F1 extend to all of the single-core optical connectors 17 of the conversion module. Id. at 7:52– 11 There is no dispute on this record that the term “module” as used in Fukui is analogous to the term “cassette” as used in the ’423 patent. 8:6. Thus, conversion module 20 is recognizable has having a singular system of fiber optic components within its body.” slip op. at 23

“Patent Owner contends that we should deny institution under 35 U.S.C. § 325(d) “because the Petition presents ‘the same or substantially the same prior art or arguments previously . . . presented to the Office.’” Prelim. Resp. 25–31 (alteration in original). Specifically, Patent Owner explains, the Office previously considered Sedor during the ’542 patent’s prosecution, and Sauter was made of record but not considered during prosecution. Id. Patent Owner, however, states that it “recognizes that this argument only reaches Sauter-based grounds, not Fukui-based grounds. This argument thus only needs to be addressed after the Board confirms the fundamental deficiencies in Petitioner’s Fukui-based grounds.” Id. at 25 n.3. Because, as set forth below, we do not, on the present record, find any “fundamental deficiencies in Petitioner’s Fukui-based grounds” that inhibit institution of trial, we regard Patent Owner’s § 325 request as moot, and we need not consider it further.” slip op. at 10

“Petitioner contends that one of ordinary skill in the art “would have [had] a B.S. degree or equivalent in mechanical or electrical engineering or similar fields, in addition to a minimum of two years of professional experience with or graduate studies involving design, development, and/or utilization of optical communication systems.” Pet. 26. On the present record, Patent Owner does not dispute this proposed level of skill. Prelim. Resp. 1–31. Neither party explains why the outcome of this case would be affected by the adoption of any of the proffered definitions of a person of ordinary skill in the art. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as it appears consistent with the ’542 patent and the asserted prior art. See Okajima v.

“enough to resolve . . . the lead Fukui ground” but that “[t]here are two disputes relevant to the alternative Sauter ground.” Pet. 22. With respect to the first of these “disputes,” Petitioner presents two claim constructions for the claim term or phrase “cassette width as measured between outer side edges thereof of one of one, two, three, four and six standard width units.” Id. at 23. The constructions are said to be from “the co-pending litigation,” with one characterized as “Patent Owner’s proposed construction”6 and the other as “CommScope’s proposed construction.”7 Of note is Petitioner’s 6 The claim construction attributed to Patent Owner is: “cassette width as measured between the outer side edges thereof that accommodates one of one, two, three, four, or six receptable modules.” Pet. 23. 7 Petitioner’s construction is: “The cassette width as measured between the outer side edges thereof equals one, two, three, four, or six times the contention that “[Patent Owner]’s construction cannot be correct,” and accompanying explanation in that respect. Id. at 22–23, 24. Patent Owner acknowledges that there is a dispute between the parties as to the noted claim construction but urges that “[t]he Board, however, need not fully resolve this claim construction dispute,” as, in Patent Owner’s view, the grounds based on Sauter are deficient based on either construction. Prelim. Resp. 21–22. We are mindful of Petitioner’s view that Patent Owner’s litigation construction is not correct. We also question whether that construction adds clarity in substituting “width that accommodates” for “width of,” and replacing “standard width units” with “receptable modules,” without, on this record, support for such word variations. Nevertheless, our determination whether to institute trial does not require resolution of any claim construction dispute, nor does it necessitate that we adopt any particular construction for the pertinent claim term. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted
“Stated somewhat generally, the core question underlying Patent Owner’s challenge to Petitioner’s Fukui-based grounds is whether a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette. We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and 10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) and forming “one body” (see, e.g., id. at 8:2–3).

Id. at 7:52– 8:6. Thus, conversion module 20 is recognizable has having a singular system of fiber optic components within its body. At this time, we regard such characterization of the coupled unit modules 10A and 10B as reasonably giving rise to an understanding that the resulting conversion module 20 constitutes a unitary module or cassette component.” slip op. at 20
