“Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). On its face, the language “energy transfer signal” does not specify any restrictions on the type of system in which it is utilized, nor its characteristics. In the context of claims 1 and 11, the “energy transfer signal” is the basis on which the “switch” operates, so as to “sub-sample and transfer energy from a first electromagnetic (EM) signal.” Ex. 1001, 50:63–65, 51:56–58. Accordingly, based on the claim language, the term “energy transfer signal” need only be a signal for operating a switch to sub-sample and transfer energy from an electromagnetic signal. That is its plain and ordinary meaning.” slip op. at 15

“’686 patent broadly includes knowledge and experience as to RF circuit design. See supra § III.B. Petitioner contends that “Nevo’s transceivers [102a/102b] are for Bluetooth and IEEE 802.11,” and that a person of ordinary skill in the art would have understood that both protocols “required down-conversion in their receivers to obtain a baseband signal.” Id. at 35 (citing Ex. 1004, 4:45–50; Ex. 1002 ¶ 118). Nevo’s disclosure would have motivated a person of ordinary skill in the art to look to Avitabile, which provides the circuit level detail for down-converters. See Ex. 1006, Abstract. Avitabile specifically provides circuitry for down-conversion in the s-band frequency range, which is in the range of Bluetooth and IEEE 802.11 (2.4 GHz). Id. at Abstract, Figs. 6, 7. Accordingly, we determine a person of ordinary skill in the art would have been motivated to look to down-converters in the range of frequency needed, and would have been motivated to combine Avitabile’s teachings with those of Nevo, with a reasonable expectation of success.” slip op. at 55

“Turning to the substantive issues, we find the District Court’s “mirror tracking mode” construction to be well-reasoned and supported by the record, and we therefore adopt that construction and its reasoning. As the District Court points out, both the “double the distance” and “same size” aspects of its construction are expressly discussed in the ’109 patent, which is incorporated in the ’110 patent. See Ex. 2008, 16 (citing Ex. 1021, 2:5–27, Figs. 5A, 5B), 40 (citing “same reasons set forth regarding the term ‘it appears to mimic a reflection of a mirror’” in support of construction of “mirror tracking mode”).

“persuasively address limitation 1[f]’s “mirror tracking mode.” In particular, Petitioner does not address persuasively the requirement, as explained in Section II.B above, that mirror tracking mode involves processing camera-captured images in a way that “maintains roughly the same size regardless of the user movement.” At odds with this requirement, Petitioner founds its case on an assertion that “Haan teaches the claimed mirror tracking mode” because “if the viewer is within 35 cm of the camera, a tracking mode is entered, applying resizing transformation.” Pet. 44 (emphasis added) (citing Ex. 1005 ¶¶ 75–76, 80–82, 90–94, 97; Ex. 1003 ¶¶ 205–210). The resizing transformation Petitioner references actually involves magnifying the user’s image by an amount that changes based on the user’s position relative to the camera, quite the opposite of maintaining image size regardless of the user movement. Ex. 1005 ¶¶ 75–76, Fig. 8. Thus, Petitioner’s initial position is unpersuasive. Petitioner’s shift to Haan’s “reflective mirror mode and conventional mirror period in the dual mode” is also unavailing. Reply 8. Consistent with Patent Owner’s arguments, Petitioner does not provide persuasive evidence that these operating states of Haan’s device involve any processing of camera-captured images. Sur-reply 13–14. To the contrary, Haan suggests that anytime its device provides an unmagnified image, it comes from a reflection off a physical reflective surface. See, e.g., Ex.1005 ¶ 76 (“This can be done for instance by using the device as a simple mirror, i.e. not displaying an image on the display device, but using the device in the reflective mode.”) (emphasis added), ¶ 92 (“a simple reflective mode, to act as a mirror”), ¶ 29 (“for a first range of positions, no image is displayed, whereby the reflective layer acts as a mirror, and for a second range of positions, the recorded image is displayed.”) (emphasis added). We also find unpersuasive Petitioner’s Reply arguments based on Haan’s disclosure of smoothly transitioning from “using the device as a simple mirror” (i.e., using a physical reflecting surface) to displaying a magnified image. Reply 11 (citing Ex. 1005 ¶¶ 76, 80). To the extent this may establish a point around the transition at which Haan’s system displays an image with relatively little magnification, it does not establish that Haan teaches, suggests, or renders obvious holding the displayed size roughly constant, “regardless of the user movement.” Indeed, given Haan’s focus on helping the user see things more clearly with image magnification, Petitioner’s argument that it would have been obvious to hold the size of the image constant is not persuasive. See, e.g., Ex. 1005 ¶ 4. Thus, on the whole, Petitioner’s shifting, scattered arguments do not persuasively address limitation 1[f]. Accordingly, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over Haan and Francois. And Petitioner’s arguments and evidence addressing claims 2–6, 10–12, 16, and 17 do not cure the foregoing deficiencies in the challenge of claim 1. Pet. 46–52. Accordingly, Petitioner has not shown by a preponderance of the evidence that any of claims 1–6, 10–12, 16, and 17 would have been obvious over Haan and Francois.” slip op. at 23

“We do not agree. Petitioner demonstrates persuasively that a person of ordinary skill would have combined these references “to correct image distortions and provide a more realistic mirror image.” Pet. 52–55; Ex. 1003 ¶¶ 242–249. We are not persuaded by Patent Owner that by specifically disclosing “flipping” the image, Rosenberg is discouraging or teaching away from performing other transformations to achieve its objective of “replicat[ing] the performance of a standard household mirror.” See PO Resp. 35, 38–39 (Patent Owner asserting lack of motivation to combine the references). A reference may be said to “teach away” “when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” Galderma Lab'ys, L.P. v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013) (quoting DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed.Cir.2009)). “A reference does not teach away, however, if it merely expresses a general preference for an alternative invention but does not criticize, discredit, or otherwise discourage investigation into the invention claimed.” Id. Further, when conducting an obviousness analysis, the Board must consider a prior art reference “not only for what it expressly teaches, but also for what it fairly suggests.” Bradium Techs. LLC v. Iancu, 923 F.3d 1032, 1049 (Fed. Cir. 2019) (quoting In re Baird, 16 F.3d 380, 383 (Fed. Cir. 1994)). We are not convinced that the references before us “teach away” from performing the other transformations. In sum, we find for the reasons given that Petitioner has demonstrated by a preponderance of evidence that to a person of ordinary skill, Rosenberg alone or with Park teaches or suggests limitation 1[f].” slip op. at 44

Petitioner persuades us that limitations 1[c] and 1[e], would have been obvious over Rosenberg and Park, in combination. Pet. 58–64; Reply 19–20. Patent Owner’s counter arguments are unavailing for multiple reasons. Patent Owner’s arguments fail because they improperly attack Rosenberg’s teachings individually, rather than addressing Petitioner’s combination of the references. PO Resp. 39–40; Sur-reply 19. This is fatal to Patent Owner’s arguments. In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Moreover, Petitioner presents persuasive arguments and evidence that the references, in combination, teach limitations 1[c] and 1[e], including persuasive evidence that the references’ tilting, resizing, and zooming meet the claim limitations’ “adaptive transformation mapping . . . to generate modified images that appear to be captured from a different point of view” that “corresponds to an image taken from a different angle and a different distance.” Pet. 58–64 (citing Ex. 1001, 3:26–28; Ex. 1003 ¶¶ 65–67, 253–268; Ex. 1006 ¶¶ 26–28, 50, 52, 61, 75 ; Ex. 1011 ¶¶ 50–51, 59, Figs. 6A–6B, 7, 8, 14, 15; Ex. 1019, 16–20; Ex. 1021, 2:19–27, 17:19–24, 21:60, 23:65–24:9, 25:46–48, 30:4–11, Fig. 11); Reply 19–20 (citing Ex. 1003 ¶¶ 253–268; Ex. 1021, 17:17–23; Ex. 2012, 63:13–22, 111:13–21). Regarding tilting, after noting the ’110 patent’s disclosure (incorporated from the ’109 patent) of performing tilt transformations (Pet. 10–11), Petitioner advances persuasive evidence that Park discloses such a tilting transformation, thereby teaching the claimed “different angle” (id. at 61–63). Regarding resizing and zooming, citing extensive discussion in the ’110 patent (incorporated from the ’109 patent) of resizing and/or zooming to address the effects of varying distance between an object and a camera, Petitioner and Dr. Karam explain that the prior art’s zooming and resizing meet the claimed “different distance.” Pet. 63 (Ex. 1001, 3:26–28; Ex. 1021, 17:19–23, 21:57–60, 23:65–24:9, 25:46–48, 30:4–11, Fig. 11); Ex. 1003 ¶ 265 (citing Ex. 1001, 3:26–28; Ex. 1021, 17:19–23, 21:57–60, 23:65–24:9, 25:46–48, 30:4–11, Fig. 11). In its counterarguments, Patent Owner suggests that zooming and resizing do not account for “occlusion effects,” but Patent Owner does not persuasively tie this argument to the ’110 patent, failing to cite any portion of the ’110 patent that evinces its invention addresses such effects.

This portion of Figure 6B depicts representations of two files: “FamilyHistory.docx” and “XmasLetter-2012.pdf.” The ’906 application specifically states: [A] located data resources dialog UI element 630b . . . includes a presentation space 632b for presenting a user detectable representation of some or all of the data objects identified in the received data object identification response from . . . second node 504. Ex. 2004 ¶ 147 (emphasis added). The entries in the above figure are representations of the files, not the files themselves. The actual files are stored in the file system storage associated with the user’s node, and only retrieved if the user selects the “Access” or “Access All” elements. Id. ¶ 148. Patent Owner misconstrues the claim 22 language, “a first representation of the at least one file, in a location among one or more folders, that is stored at the at least one server” and “a second representation of the at least one file, in a location among one or more folders, that is stored at the first node.” Patent Owner infers from this language that the representation is itself a file that is “in a location among one or more folders” and is stored on a server or at a node. PO Resp. 17. Not so — the representation of a file, such as “FamilyHistory.docx” in the above figure, is not stored at a server or node, but rather is simply displayed on a screen. As the ’906 application states: A representation of a program entity may be stored and/or otherwise maintained in a presentation space. As used in this document, the term “presentation space” refers to a storage region allocated and/or otherwise provided for storing presentation information . . . . A screen of a display, for example, is a presentation space.” slip op. at 22

“We agree with Petitioner that set content field 325 of Riepling teaches or suggests claim requirement 9[b]. As Petitioner’s expert explains, the fact that field 325 has an appearance identical to that of fields 321–324 in Figure 3, which fields are specifically stated to be “text field[s],” strongly suggests that field 325 is also a text field. Mowry Decl. ¶ 70; see also Reply 10–11. Patent Owner’s suggestion that field 325 could be a dropdown list or other type of field is contradicted by the fact that it does not show the typical dropdown arrow associated with a dropdown box, or other typical non-textbox appearance such as the checkbox appearance of field 320. Moreover, in the example of Figure 3, the “Set Content” entry is “audio,” which is a file description. Reply 10. The fact that “JPEG” is checked in field 320 is not inconsistent with the “audio” entry in field 325, given that, as Riepling explains, “it may be possible for audio files such as MP3 files to contain non-MP3 data, such as JPEG data embedded within the MP3 files.” Id. at 11 (citing Ex. 1107 ¶ 32; Mowry 2nd Decl. ¶ ¶ 101–104).

“We conclude that there is no basis for Patent Owner’s proposed construction of “representation of the at least one folder.” Petitioner is correct that a representation of a folder is not the folder itself, but (in keeping with the ordinary meaning of “representation”) is rather some sign or symbol that stands for the folder. Reply 2. This is confirmed by the explicit example of a representation of a folder in the ’635 application, illustrated in the portion of Figure 6D reproduced below (highlighted here for purposes of explanation). This portion of Figure 6D depicts representations of several folders, including the highlighted “Music” folder. The ’635 application specifically states: A folder content pane UI element 648d in navigation window UI element 646d is presented including representations of one or more data objects[11] at a location, identified in a path UI element 650d. A pointer UI element 652d illustrates a drag and drop operation of a “Music” folder represented in contents pane UI element 648d, dropped on edit window UI element 602d. Ex. 2004 ¶ 123 (emphasis added). The word “Music” in the above figure is a representation of a folder, not the folder itself.

“Patent Owner’s arguments are not pertinent to Petitioner’s proffered combination of Houston with Garcia as applied to the remaining challenged claims 17–21. As discussed further below, Petitioner relies on Garcia as supplementing Houston for details regarding the requirements of generating and sending an email with a link to a folder but without a file attachment, and for synchronizing folders and providing interfaces for display of shared folders. Pet. 26–27, 36–39, 57–60. For the challenged claims, Petitioner does not need to rely on the combination to modify Houston’s system such that, when an icon for a shared folder is created in Houston’s interface at an invited user’s client, the client does not store a file in the shared folder — 14 For this argument and others, Patent Owner cites for additional support portions of U.S. Provisional Patent Application No. 61/233,787. PO Resp. 18, 42, 46; Sur-Reply 9–12. This application is designated in Houston as a related application, and incorporated by reference therein. Ex. 1003, code (60), 1:6–10. We denied as untimely Patent Owner’s request to belatedly add this application to the record. Ex. 3002; Paper 39. Even accepting Patent Owner’s representations of the relied-on disclosures in that application, those disclosures are cumulative to Houston’s criticisms of systems that store documents remotely, and are irrelevant for the same reasons as discussed herein with respect to those Houston disclosures. that aspect of the Houston/Garcia combination is only relevant to claims 1–8, which have been disclaimed. Id. at 40–41; Ex. 2045.15 Thus, Patent Owner’s argument that Houston teaches away from combining with Garcia to delay storing a file when a folder is shared is not applicable to Petitioner’s challenges of claim 17–21, in light of our conclusion set forth above in Section III.C rejecting Patent Owner’s proposed construction of claim 17. The fact that the Houston system ensures the availability of synchronized local copies of files at each user’s local system and criticizes systems that store documents remotely, such as in Garcia, is irrelevant to those claims. On this record, there is nothing about that particular difference in the approaches of Houston and Garcia that would support a finding that one of ordinary skill in the art would have been discouraged from adopting Houston to take advantage of the teachings in Garcia regarding use of email and folder interfaces. In sum, Patent Owner focuses on a specific irrelevant detail of Houston regarding local storage of files, whereas Petitioner relies on other features of the combination of Houston and Garcia.

“To give substantial weight to objective indicia of nonobviousness such as commercial success, a proponent must establish a nexus between the evidence and the merits of the claimed invention. ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016). Nexus is a legally and factually sufficient connection between the objective evidence and the claimed invention, such that the objective evidence should be considered in determining nonobviousness. Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” ClassCo, 838 F.3d at 1220 (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)). A patentee is entitled to a presumption of nexus “when the patentee shows that the asserted objective evidence is tied to a specific product and that product ‘embodies the claimed features, and is coextensive with them.’” Fox Factory, Inc. v.

The Federal Circuit has held that “if the marketed product embodies the claimed features, and is coextensive with them, then a nexus is presumed and the burden shifts to the party asserting obviousness to present evidence to rebut the presumed nexus.” Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1130 (Fed. Cir. 2000). “A finding that a presumption of nexus is inappropriate does not end the inquiry into secondary considerations”; rather, “the patent owner is still afforded an opportunity to prove nexus by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Fox Factory, 994 F.3d at 1373–74 (quoting In re Huang, 100 F.3d 125, 140 (Fed.

“However, as Petitioner argues above, Houston discloses that a client can provide an email to the server to invite others to share a folder, and Houston explains that “attaching files [to emails is] cumbersome for many computer users.” Pet. 25–26 (citing Ex. 1003, Fig. 4, 1:41–42, 3:40–43, 7:50–51). From this, Petitioner argues that it would have been obvious for the email invitation to notify how to access the folder, rather than sending the folder contents itself. Id. Petitioner further argues that the claim 17[d] requirement would have been obvious over the combination of Houston and Garcia given the disclosure in Garcia of sharing a folder by sending an email with a link to the folder, instead of an attachment. Id. at 27, 57 (citing Ex. 1004, Figs. 9, 11–12, 10:32–34, 10:38–40, 11:39–43, cl. 3). We are persuaded that the record supports Petitioner’s arguments regarding this claim requirement. Both Houston alone, and the combination of Houston and Garcia, teach or suggest sending an email with a link to a folder to be shared, rather than the folder contents. Only if the recipient clicks on the link are the contents of the folder shared. Ex. 1004, 11:29–31. The act of clicking on the link in the email after the email is received is the required “initiation of the communication” that must occur separately from the email itself, as required by claim 17[d]: “causing generation of at least one email [that] does not include a file attachment, for permitting avoidance of at least one file from being communicated to and stored at the second node until an initiation of the communication of the at least one file by a user of the second node is detected and the communication commences via at least one server that stores the at least one file” (emphasis added). It does not matter if Houston or Garcia automatically downloads local copies of files when a recipient clicks on the email link, because that is a separate step following the step of claim 17[d].” slip op. at 46

But neither party proposes a construction for “data chunks” in this proceeding. Notably, the 83-column Specification of the ’609 patent itself does not use the term “data chunks.” Even so, the meaning of “data chunks” is readily apparent from the plain language: the data chunks are generated “based on a data set,” and the claim defines the steps that comprise the chunk generation, including the relationship between the chunks and the data set.

Bigbee’s firmware FRC logic does not determine if lockstep is recoverable. Id. Similar to Bigbee, Nguyen also uses firmware FRC logic to check for an error within a processor core. See Ex. 1006 ¶¶ 9, 18, Fig. 7. However, the difference is that Nguyen’s firmware FRC logic determines if lockstep is recoverable. Id. We find for the reasons given by Petitioner and Dr. Brogioli including those summarized supra, that it would have been obvious to one of ordinary skill in the art to modify Bigbee by implementing Nguyen’s determination in firmware. Pet. 33–35 (citing, e.g., Ex. 1002 ¶ 94 (stating that “[i]mplementing logical steps in firmware was known in the art”); ¶ 95 (stating that Bigbee’s system “is compliant with well-known industry standards”); ¶ 98 (stating that “firmware is flexible” and “can be modified after production, updated, and supported relatively quickly and inexpensively.”)). In contrast, Patent Owner’s arguments fail to convince us that a person of ordinary skill in the art, having knowledge of Nguyen’s teaching of determining lockstep recovery, would not have able to modify Bigbee’s firmware FRC logic to determine if lockstep is recoverable. See KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”); see also id. at 418. Accordingly, Petitioner has presented reasoning, with rational underpinnings, that a person of ordinary skill in the art would have had reasons to modify Bigbee’s firmware FRC logic based upon Nguyen’s teachings and would have had a reasonable expectation of success in doing so. Accordingly, we find for the reasons given that Petitioner demonstrates by a preponderance of the evidence that this element is taught or suggested by the Bigbee/Nguyen combination.” slip op. at 29
