“the ’478 patent, the applicant clearly and plainly informed the Office that an “[e]xemplary” embodiment of “searching the first temporary storage location for the archive file,” as recited in then-pending claim 34 and step [1.4] of issued claim 1, is found at specifically cited portions of the ’478 patent specification. See Ex. 1002, 147 (“Exemplary support may be found at . . . .”). Those specifically cited disclosures describe how smart data manager 15 “examines” input buffer 20 “for the presence of archive files” or equivalently “to determine whether any archive files are stored therein.” Ex. 1001, Fig. 2A (step 100), 5:39–42, 6:19–27. Based on this prosecution history, we conclude that in one embodiment of claim 1, searching the first temporary storage location for the archive file per step [1.4] is satisfied by examining the first temporary storage location for the presence of an archive file. We reach this conclusion even if the referenced portions of the ’478 patent specification are not regarded as being definitional with respect to the “searching” requirements of step [1.4].” slip op. at 26

“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).

“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.

“Statutory Deadline We weigh this factor as favoring the exercise of discretionary denial.

Supp. Br. 4; Prelim. Resp. 19–20. Because the currently scheduled District Court trial is set to begin six months before our deadline to reach a final decision, this factor favors discretionary denial in this case. See Fintiv, Paper 11 at 9. C. Factor 3 – Investment in the Parallel Proceeding We weigh this factor as favoring the exercise of discretionary denial. Showing substantial investment in the District Court litigation, document production is substantially complete and fact discovery will be completed within two weeks of this Decision on Institution.

Furthermore, we must consider this parallel work in relation to the October 6, 2025 District Court litigation trial date, which is six months before the projected statutory deadline of our Final Written Decision. See Fintiv, Paper 11 at 10. As work in the District Court litigation has moved beyond preliminary stages into more advanced stages, instituting at this time implicates at least some duplicative costs. See id. On the matter of petition timing, it is often reasonable for a petitioner to wait to file its petition until it learns which claims are being asserted against it in the parallel proceeding. Fintiv, Paper 11 at 11. Here, Petitioner filed its petition on September 27, 2024, which is four months after receiving Patent Owner’s May 29, 2024 disclosure of asserted claims and infringement contentions and nine months after it was served Patent Owner’s December 29, 2023 infringement complaint. Ex. 1017; Ex. 1018, 1. Further, Petitioner served its amended invalidity contentions in the District Court litigation on December 17, 2024, i.e., after it filed its Petition.5 We do not find the timing of the Petition in this case to outweigh the significant investment in the District Court litigation.

Id. at code (57), Fig. 3, 1:63–65, 2:23–25, 3:26–28, 9:47–49; see also Superguide Corp. v. DirecTV Enter., Inc., 358 F.3d 870, 875 (Fed. Cir. 2004) (“Though understanding the claim language may be aided by explanations contained in the written description, it is important not to import into a claim limitations that are not part of the claim. For example, a particular embodiment appearing in the written description may not be read into a claim when the claim language is broader than the embodiment”).” slip op. at 21

“combine the teachings of Peterka, Suzuki, and Bocharov. Pet. 51–53, 57– 59, 66–67. Petitioner argues that Suzuki, like Peterka, discloses clients acquiring keys for multiple media segments, and provides implementation details, not disclosed in Peterka, regarding how to keep track of keys and their expiration times, and how to determine when a new key is required. Pet. 51–52 (citing Ex. 1003 ¶¶ 161–164). Petitioner argues that, given that Peterka and Suzuki are in the same field of art, one of ordinary skill would have been motivated to use the specific details of Suzuki in implementing the disclosure of Peterka. Id. at 53, 66 (citing Ex. 1003 ¶¶ 165–167, 202–204). Petitioner also argues that Peterka indicates that video content can be streamed using various protocols and bit rates, but does not provide implementation details. Pet. 57–59, 66–67 (citing Ex. 1003 ¶¶ 179–184, 204). However, argues Petitioner, one of ordinary skill in the art would have had reason to use the manifest files of Bocharov to provide the necessary information to handle different protocols and bit rates. Id. Petitioner argues that one of ordinary skill in the art would have been so motivated because implementing Peterka’s system to use Bocharov’s manifests would have provided an effective solution for allowing clients to switch between multiple versions of a media program having different encodings/qualities/bit rates. Id. Patent Owner does not specifically address the merits of combining Peterka, Suzuki, and Bocharov. See generally Prelim. Resp. Nonetheless the burden remains on Petitioner to demonstrate unpatentability. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). For purposes of this Decision, we determine that Petitioner has provided sufficiently articulated reasoning with rational underpinnings for the proffered combined teachings of Peterka, Suzuki, and Bocharov.” slip op. at 29
