      “December 18, 2012, would have a bachelor’s degree in electrical or computer engineering, or a closely related field such as computer science, and two years of work experience with image capture and processing systems or related fields.” Pet. 7 (citing Karam Decl. ¶ 91). Petitioner adds that “[a] person with less and/or different education, but more relevant practical experience, or vice versa, may also meet this standard.” Id. According to Petitioner, [t]he prior art also evidences such level of skill.” Id. Patent Owner states that it “applies Petitioners’ proposed level of skill for purposes of this Response.” PO Resp. 9 (citing Forsyth Decl. ¶¶ 53–54).

      “Post-institution, Patent Owner invites us to construe limitation 1[f]’s recitation of “mirror tracking mode” and limitation 1[c]’s recitation of “adaptive transformation mapping.” PO Resp. 9–14. Regarding the latter, Patent Owner explains that “[i]n the District Court Litigation, ‘adaptive transformation mapping’ was construed as ‘continuously variable transformation mapping’ and ‘transformation mapping’ was construed as a ‘selected set of image transformations.’” Id. at 14 (citing Ex. 2008, 14, 37; Ex. 2013 ¶¶ 25, 27). Patent Owner does not, however, identify any way that those claim constructions affect our analysis of the parties’ patentability disputes.

      “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).

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.

      “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.

We are not convinced that the references before us “teach away” from performing the other transformations.

      “shows by a preponderance of the evidence that limitations 1[c] and 1[e] are taught or suggested by Rosenberg and Park, in combination. Pet. 58–64; PO Resp. 39–40; Reply 19–20; Sur-reply 19. 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.

      “construction of “representation of the at least one file.” Petitioner is correct that a representation of a file is not the file 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 ʼ906 application, illustrated in the portion of Figure 6B reproduced below (highlighted here for purposes of explanation). 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 . . . .

      “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). Also, there is no reason why the Figure 5 response that gives the uploader the ability to provide additional description of the file being uploaded is inconsistent with the ability of the requester first describing what type of file is being requested via field 325 in Figure 3.

      “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.

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.

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. Cir. 1996)). “Ultimately, the fact finder must weigh the [objective indicia] evidence presented in the context of whether the claimed invention as a whole would have been obvious to a skilled artisan.” See Lectrosonics, Inc. v.

      “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

      “Ex. 1005 ¶ 0111. Dr. Rubin testifies, succinctly, that “I do not believe that a [person of ordinary skill] would understand that Tajima uses the term ‘information regarding the key’ to refer to the key. If Tajima meant to say the ‘key,’ there would be no need to use the phrase ‘information regarding the key.’” Rubin II Decl. ¶ 41.

Id. ¶ 42 (citing Ex. 1005 ¶¶ 67, 70, 71, 75, 77, 86, 88, 89). We find Dr. Rubin’s reasoning on this issue persuasive. On the other hand, we find Dr. Bhattacharjee’s response less convincing.

Lacking support for disclosure of an encryption key in Tajima itself, Dr. Bhattacharjee turns to other references, including Foster. Id. ¶¶ 7–9. Dr. Bhattacharjee testifies that “Foster’s use of the term ‘key information’ to describe information that includes the key and additional information . . . explains why Tajima did not just say ‘key’ when referring to the information attached to the data fragments.” Id. ¶ 8. Dr. Bhattacharjee’s testimony is unconvincing. In Foster, there is explicit disclosure of including the encrypted title key itself in the header extension. Ex. 1006 ¶ 66 (“As depicted, header extension 118 includes encrypted title key 112 . . . “). In contrast, Dr. Bhattacharjee cites no similar disclosure in Tajima. In fact, Dr. Bhattacharjee’s reliance on other references to support anticipation runs contrary to the rule that “[a] claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987) (emphasis added). We do not find Dr. Bhattacharjee’s testimony based on Foster and other references convincing of anticipation by Tajima. Nor do we find Petitioner’s alternative obviousness challenge based on Tajima persuasive. Pet. 22. The Petition includes a single-sentence explanation of this obviousness contention: “Even if Tajima had not disclosed that its key information includes the corresponding key, that would have been an obvious and conventional way to implement what Tajima discloses—i.e., a system that needs only the key information to decrypt data fragments and not additional key management infrastructure.” Id.

Patent Owner argues Foster’s disclosure of a KEK would have been “redundant” to Tajima’s key-securing obfuscation technique. PO Resp. 18. We find this argument is unavailing. As Petitioner points out, Patent Owner’s argument “ignores Tajima’s vulnerability that Foster’s key-encryption addresses.” Pet. Reply 16. More specifically, “[r]equiring an attacker to obtain KEKs to decrypt Tajima’s encryption keys in addition to de-obfuscating them is not ‘redundant’ to only having to de-obfuscate them.” Pet.

Patent Owner further argues that Tajima and Foster address different problems and disclose solutions that are “fundamentally at odds.” PO Resp. 9–16, 25–27. Patent Owner asserts that “Foster’s system requires synchronizing the transmission of encrypted content packets with the keys used to encrypt those packets, so that each packet can be viewed immediately upon receipt.” Id. at 15 (emphasis omitted). Patent Owner attaching it to a different data fragment, the problem Foster sought to solve is the ‘need . . . for a key used to encrypt content to be itself encrypted, and transmitted as an integral part of the [same] content.’” Id.

As noted supra, for the reasons given, we find that both Tajima and Foster are in the field of securing data from unauthorized access. Pet. Reply 13. Furthermore, as Petitioner points out, we find that in Petitioner’s combination of Tajima and Foster, Tajima’s data (which does not require synchronization) is secured, not Foster’s.

See, e.g., Patent Owner’s Sur-reply, which repeats the arguments that Tajima and Foster are in a “different field,” “fundamentally at odds,” “[i]n direct contrast,” and that applying Foster’s KEK teachings to Tajima would be “redundant.” PO Sur-reply 2–9.

      “We also find persuasive Mr. Dominguez’s explanation that one of ordinary skill in the art would have understood “bore” as including stepped diameter holes, sometimes described as a bore having a counterbore. See generally Ex. 1018 ¶¶ 4–29; Reply 3–10. Three of Mr. Dominguez’s illustrative examples are reproduced in the annotated figures below. The above figures show Mr. Dominguez’s annotated illustrations from the Jackson (Ex. 1019, Fig. 3), Brånemark (Ex. 1021, Fig. 4), and Ray (Ex. 1025, Fig. 1) references as discussed at paragraphs 10, 12, and 13, respectively, of Mr. Dominguez’s Second Declaration. With reference to the above figures, Mr. Dominguez testifies that “Jackson describes a bone repair set screw in which ‘[t]he bore 27 comprises a first bore section 31, a second bore section 32,’ etc. delineated by shoulders 41, 42, etc. (Ex. 1019, 5:24– 43)” (Ex. 1018 ¶ 10); “Brånemark describes an osseous implantation device having body 1ʺ with first and second holding portions 21ʺ, 31ʺ and ‘an inner through bore with a first portion 4ʺ in the first holding portion and a second portion 5ʺ in the second holding portion.’” Ex. 1021, 4:44–46” (id. ¶ 12); and Ray discloses surgical calipers including “handle 12 having ‘stepped cylindrical bore 14,’” wherein “[c]ollar 20 of a shaft inserted in the bore ‘rests against a step of the bore 14’ (2:14–15)” (id. ¶ 13). Patent Owner responds that Mr. Dominguez’s examples “that allegedly show a single bore encompassing two or more stepped-diameter holes or a counterbore . . . . are specific to these references and divorced from the disclosures of the ’166 patent.” Sur-Reply 7. Insofar as the ’166 patent makes no mention of the term “bore” outside the claims, and Mr. Dominguez’s examples are all taken from the field of orthopedic surgery, we do not find this argument persuasive. Patent Owner further appears to contend that exemplary references to a “cylindrical stepped down bore” or a “stepped cylindrical bore” are too specific to be within the scope of the term “bore.” Sur-Reply 7–8. As these terms merely describe species within a larger genus, and Patent Owner presents no cogent reason to exclude them, we do not find this argument availing. Relatedly, we are also not persuaded by Patent Owner’s argument that “the prior art treats a ‘bore’ as an element that is distinct from a ‘counterbore.’” Id. at 8. Rather, we credit Mr. Dominguez’s testimony that “[a] counterbore is not a structure unto itself, a counterbore is part of a larger structure” as exemplified by numerous examples including Laps (Ex. 1028 ¶ 33 (sensor assembly wherein “bore 16 includes a counterbore 18”)); Martinez (Ex. 1029, 3:61 (surgical cutting instrument wherein “bore 56 has a counterbore 64”)); Zang (Ex. 1030, 2:49 (bone anchor having a “bore [that] includes a counterbore”)); Ledet (Ex. 1022, 29:3–5 (vertebral fixation plate having “through holes . . . . countersunk, or counterbored to accommodate the head of a bone screw”)); Seo (Ex. 1031, 3:45 (chair leg employing “counterbored bore 23”)); and Exner (Ex. 1032, 2:16 (extrusion press including “counterbored axial bore 6”)). Ex. 1018 ¶¶ 17–23. That a reference may refer to a figure as showing “bore 103” with “counterbore 105 . . . formed on one end” does not indicate that they are distinct structures as Patent Owner contends, but merely that the focus of each term is directed to the entire bore or to a particular aspect of the bore, i.e., its counterbore.

      “Patent Owner subsequently proposed an alternative definition, as a person having “[a] Bachelor’s Degree in biomedical and/or mechanical engineering or similar training and . . . at least three years of experience with implant devices used for internal fixation of bones.” POR 5 (citing Ex. 2012 ¶¶ 32–33). According to Patent Owner, “[t]his hypothetical person would be capable of performing various design tasks and would understand the basic mechanical features and operation of orthopaedic implant devices [and] have an appreciation for orthopaedic fusion techniques and the medical issues and concerns faced by a doctor/surgeon charged when performing operations to implant orthopaedic devices.” Id. Despite some differences in wording, Patent Owner asserts (and Petitioner does not contest) that any “distinction between the parties’ proposed definitions of a POSITA does not affect the arguments set forth herein.” Id. (citing Ex. 2012 ¶ 34). Consistent with this view, we find the parties’ constructions equally applicable in light of the prior art of record and the disclosure of the ’166 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” as evidence of the ordinary level of skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). We adopt, for convenience, Petitioner’s definition, but our analysis does not change depending on which of the two articulations are applied here. H.” slip op. at 12

      “one of ordinary skill in the art would understand that “bore,” as used in the context of claims 1 and 12, encompasses a multi-diameter passage, and in particular, one having stepped longitudinal cross sections such as that shown in Cognet’s Figure 1. See generally DI 11–13. For the reasons that follow, we conclude that one of ordinary skill in the art would have understood “bore” as such. Relying on the testimony of Mr. Dominguez, Petitioner initially proposed a construction of “bore” as “a usually cylindrical hole made by or as if by the turning or twisting movement of a tool.” Pet. 16 (citing Ex. 1002 ¶ 58). Petitioner’s proposal relied on Mr. Dominguez’s testimony that “[a] bore is a cylindrical hole made by the spinning rotation of a twist drill cutting tool. It is typically made by removing material from a solid or hollow object, similar to a tunnel or orifice.” Ex. 1002 ¶ 58. Pointing to its annotation of Cognet’s Figure 1, above, Patent Owner argued that that the term “bore” excludes a tunnel made by “two adjacent bores.” See Prelim. Resp. 21–25. In view of the then-available evidence, we provisionally construed “bore” as a hole or passage made by or as if by the turning or twisting movement of a tool such that its interior walls have cylindrical lateral cross-sections, and which do not exclude holes or passages having tapered or stepped longitudinal cross-sections.

      “Petitioner contends that a person of ordinary skill in the art at the time of the invention (“POSA” or “POSITA”) would have had “a bachelor’s degree and two or more years of experience or a master’s degree in organic synthesis or chemical engineering, with education substituting for experience and vice versa.” Pet. 15 (citing Ex. 1002 ¶ 16). Patent Owner took no position on the level of ordinary skill in the art in its Preliminary Response. Prelim. Resp. 8. In our Institution Decision, we adopted Petitioner’s definition. Dec. Inst. 6–7. In its Motion to Amend, Patent Owner states that it accepts the Board’s definition for purposes of this proceeding. MTA 24. We, therefore, see no reason to disturb our definition of the level of ordinary skill in the art as it appears to be consistent with the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Although neither party expressly proposes a construction for the term “conversion,” the parties appear to differ in their interpretations of that term. Petitioner interprets “conversion” to mean the percent conversion of the 1- alcohol. See Pet. Opp. RMTA 6–7 (interpreting “conversion” as percentage of remaining 1-alcohol); Ex. 1040, 109:2–11. Patent Owner, on the other hand, interprets “conversion” to mean the total percentage of alkenes that have been produced. Ex. 2010 ¶ 123 (interpreting “conversion” as percentage of total alkenes). During oral argument, counsel for Patent Owner conceded that “conversion can mean either.” Tr. 27:18–28:13. Without the benefit of briefing by the parties, we decline to expressly construe the term “conversion,” as our Decision would be the same under either interpretation, as discussed further below. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “2. Analysis A patent claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which said claimed invention pertains. See also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) objective evidence of nonobviousness.
