“An obviousness determination requires finding both ‘that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.’” CRFD Research, Inc. v. Matal, 876 F.3d 1330, 1340 (Fed. Cir. 2017) (quoting Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367– 68 (Fed. Cir. 2016)). Obviousness grounds must be supported with “articulated reasoning with some rational underpinning” and not by “mere conclusory statements.” See KSR Int’l Co., 550 U.S at 418. slip op. at 11

“agree with Patent Owner that Petitioner has not sufficiently shown for institution that Bansal teaches or suggests arranging light sources “such that a higher intensity of light is emitted proximate the second edges compared to the intensity of light emitted not proximate the second edges,” as required by the challenged claims. Instead, Petitioner demonstrates how Bansal describes varying the density of light source distribution throughout the array to provide a higher density of light in the entire peripheral area of the array, which includes the areas proximal to both the first and second edges, as compared to the central area of the array. See Pet. 36–37; Ex. 1005 ¶ 25. In this regard, Petitioner relies on Bansal’s Figure 9b, asserting that it “shows one embodiment where more light sources are placed near the edges of the panel compared to the light sources in the center.” Pet. 36–37. The comparison of Bansal’s light density between the entire periphery and the central area of the array is insufficient. What is missing from Petitioner’s argument and discussion of Bansal is how Bansal teaches or suggests a configuration that provides a higher density of light proximate to the second shorter edges of the periphery in comparison to the remaining areas of the array, which includes the first longer edges of the periphery. Without that discussion, we find that Petitioner has not shown sufficient for institution that Bansal is persuasively relied upon for the light source arrangement limitation of the challenged claims. likelihood of prevailing in its obviousness challenge of independent claims 1, 5, 16, 20, or 21, or dependent claims 2, 4, 6–8, and 17–19 over Larsen, Bansal, and Jones.” slip op. at 17

“We also find it unclear which reference Petitioner relies on for the correlating. It appears that Petitioner finds the correlating in Rockwood (the reference with the attacker profile), but if Rockwood is intended to provide the correlating, it is unclear what role Xie has in the combination. We further find that Petitioner does not adequately describe how these references might be combined. Rockwood describes a system that identifies attacks at a network edge as they occur,5 while Xie’s system looks for 5 Notably, the ’224 patent presents itself as an improvement over tools that “may reside at a network edge and may receive network events concerning the network from one or more hosts or systems” because “network edge devices have no ability to establish any sort of context from within the host or system that is generating the event.” Ex. 1001, 1:43–48. Rockwood appears to describe a network edge device. See Ex. 1004, 3:16–4:4 (“Each sensor 20 is located at a network port that receives TCP/IP packets or other similar network communications from network 100.”). similar changes across different hosts within a network over multiple days. There is insufficient explanation of how Xie’s correlating technique would be beneficial in a system like that of Rockwood. Finally, to the extent Petitioner intends to rely on Xie for correlating to an originating object, we find that reliance misplaced. Xie discloses a system that looks for corresponding changes over days across multiple hosts in a network to identify patterns that might be indicative of a problem. But Xie does not describe using correlation to identify an originating object. The correlation is between similar patterns across the network, meaning that, even when Xie identifies a correlation, it is not correlating an event to its originating object, but is merely identifying multiple close vectors (reflecting corresponding file changes) within a detection window. See Ex. 1005, 38. The system then identifies the involved hosts and files, which can be used by “system administrators [to] decide whether the updates are known administrative updates that should be suppressed, or some abnormal events that should be further investigated.” Id. at 39.

“In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (2012) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A 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 the claimed invention pertains. See 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 ordinary skill in the art; and (4) objective evidence (1966). In analyzing the obviousness of a combination of prior art elements, it can be important to identify a reason that would have prompted one of skill in the art “to combine . . . known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418. A precise teaching directed to the specific subject matter of a challenged claim is not necessary to establish obviousness. Id. Rather, “any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Id. at 420. Accordingly, a party that petitions the Board for a determination of unpatentability based on obviousness must show that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1381 (Fed.

“On the record before us, however, Dr. Flatt’s assessment of the relative benefit one of ordinary skill in the art would have accorded the higher Ki of mono-substituted compound 3 as compared to the “much longer plasma half-life” of Dong’s bi-substituted compounds is at odds with Dong’s selection of bi-substituted compound 4 for clinical trials. See Ex. 1013, 670– 671 (Table 1). We are also skeptical of Dr. Flatt’s assertion that one of ordinary skill in the art would have recognized that Dong’s substitution of Aib for alanine at position 8 “would complement and work synergistically with liraglutide’s [other] properties,” including the fatty acylation of Lys26. See Ex. 1020 ¶ 181. In this respect, Patent Owner notes that, unlike liraglutide, Dong’s GLP-1 analogs were not acylated, whereas Knudsen 2001 counseled against N-terminal modifications in the context of acylation. Prelim. Resp. 28–30, 46 (citing Ex. 1011, 680–681). In addressing such combinations, Knudsen 2001 states, for example, that “Desamino His7 represents one of the more potent suggestions to a modification giving metabolic stability (81 ). Nevertheless, as seen when comparing 19 (687 pM) to 5 [liraglutide] (68 pM), considerably more potent compounds could be obtained by not modifying the N-terminus when a combination with acylation was desired.” Id. at 680. As such, we are unpersuaded on the record before us that one of ordinary skill in the art would have had a reasonable expectation that the Aib8 modification would be beneficial or otherwise “complement and work synergistically with” the acylated Lys26 of liraglutide or semaglutide.

“Considering the record before us, Petitioner has not shown sufficiently that one of ordinary skill in the art would be motivated to make the required modification with a reasonable expectation of success. (4) Hindsight and Reasonable Expectation of Success One of ordinary skill in the art seeking to modify liraglutide would need undertake at least four discrete steps to arrive at semaglutide—some of which entail multiple options and decision points (e.g., the selection and placement of di-AEEA, and whether to replace, or add to, the existing γ-glu linker). As discussed above, we find Petitioner’s justification for these individual steps problematic. Taken as whole, and considering the vast number of modifications suggested in the art—and indeed, the large number of amino acids suggested as cites for modification—Petitioner has failed to meet its burden of demonstrating why a skilled artisan would have been motivated to make all of the identified substitutions and no others. See e.g., Ex. 1010, 4130 (Figure 3) (identifying amino acids available for derivatization (Ser18, Gln23, Lys26, Glu27, Lys34, and Arg36) or modification (Ala8)); Ex. 1011, 680–681 (identifying desamino His7 as “one of the more potent suggestions to a modification giving metabolic stability,”); Ex. 1012 at, e.g., 9:21-19:59; 192:30–60 (Table 1), 193:35–46 (disclosing numerous GLP-1 analogs, including those with greater half-lives or potency than liraglutide, and teaching that each could be further modified, including with amino acid substitutions and/or acylation at multiple positions, numerous the fatty and amino acids); Ex. 1013, 670–671 (disclosing that GLP-1 analogs bearing modifications at both positions 8 and 35 maintain efficacy but “have much longer plasma half-life than mono-substituted compounds”).” slip op. at 43

“We agree with Patent Owner that “[i]f anything, Petitioner’s cited passages appear to suggest to the contrary that these ostensible default duration parameters would instead be features of the application programs used for managing Shimizu’s alleged show structures.” Id. at 45–46; see also id. at 59 (“[T]he passages Petitioner relies on teach only that the ‘predetermined time’ would be associated with the application program used to display the nodes.”). Several considerations support this understanding of Shimizu, including both Shimizu’s disclosure and certain testimony of Petitioner’s expert, Mr. Schmandt. First, the passage that Petitioner cites from Shimizu’s Summary of the Invention refers to “an application program” that causes switching of nodes displayed “at predetermined intervals.” Ex. 1003, 5:11–14. The other passage that Petitioner cites similarly refers to “an application program” that may be displayed by reading node information within “a predetermined time.” Id. at 3:12–16. Although not cited by Petitioner, Shimizu also states: As described, the hypertext apparatus of the invention offers a user interface capable of putting into a desired order the links between the nodes to be managed and of manipulating the established link order. This makes it easy to create illustratively an application program allowing the display of node contents to be switched in a desired order and at predetermined intervals on the hypertext apparatus. Id. at 9:60–66. All of these passages are more consistent with Patent Owner’s position that the predetermined time or intervals are included in the application program rather than in the hypertext nodes. Petitioner does not provide persuasive argument or evidence to show that Shimizu should instead be read as describing hypertext nodes that include predetermined times or intervals. Second, we have also considered Mr. Schmandt’s testimony, and he provides no meaningful additional information to support reading Shimizu as Petitioner advocates. See Ex. 1002 ¶¶ 118, 120–127. In testimony not cited by Petitioner, Mr. Schmandt admits that “Shimizu does not appear to disclose further details about how duration information is specified or stored within its system, or whether such intervals between nodes can be changed.” Id. ¶ 119. This testimony undermines Petitioner’s position that Shimizu’s hypertext nodes include duration information. Mr. Schmandt elaborates in testimony that Petitioner cites, but does not explain: In a real-world implementation of the proposed combination, for example, the display time could have been specified within the node information structure 9 of Shimizu. I note that node information structure 9 in Shimizu also contains display procedure slot 62 (Fig. 6), which points to “a procedure program function used when the node in question is to be displayed on the screen.” (Shimizu, 6:52–55.) Shimizu thus contemplates that node information structure 9 may contain information about how the node will be displayed to the user, and as such, it would have been obvious that durational information could also have been included as part of node information structure 9. This durational amount could have been a default display time specified by the user, or a display time specific to the node in question, as explained above. * * * Shimizu itself clearly contemplates the ability to customize the display of nodes, and as explained above, node information structure 9 (Fig. 6) includes display procedure slot 62 which points to a program function or procedure used to display the node content, thus making clear that node information structure 9 can hold information about how the node will be displayed. Id. ¶¶ 123, 127. Mr. Schmandt’s testimony that Shimizu would need to be modified for its hypertext nodes to include duration information is strong evidence that Shimizu does not disclose hypertext nodes that include duration information.

“used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” 37 C.F.R. § 42.100(b) (2019); see Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en banc). Certain terms recited in the challenged claims were construed during prior litigation of the ’451 patent, i.e., an ancestor of the challenged ’819 patent that Petitioner characterizes as “shar[ing] a near-verbatim written description with the ’819 patent”). Ex. 1023 (claim construction order in cases involving Microsoft and Apple); Ex. 2003, 5 (clarification of certain claim constructions on summary judgment); Pet. 8–9. Patent Owner advocates that we adopt such prior constructions in this proceeding. Prelim. Resp. 6. Although “Petitioner does not believe express claim construction is necessary at this time,” Petitioner takes the position that its asserted prior art “renders the challenged claims obvious under the district court’s constructions.” Pet. 10. And we agree with Patent Owner that the Petition “presents extensive arguments” that apply the district court’s constructions. See Prelim. Resp. 6 (citing Pet. 9–10, 12–20, 33). We have reviewed the court’s claim-construction order, and adopt its construction of the following terms for purposes of this Decision. First, we construe “node,” which is recited in multiple claims, as “an identifier of a resource that includes an address to the resource and the duration for which the resource’s content is to be presented by default.” See Ex. 1023, 16–17; Prelim. Resp. 8–10. Second, we construe “show structure of nodes,” which is recited in each of challenged independent claims 1, 16, 23, and 26, as well as in certain dependent claims, as “a structure that is arranged for the display of content by specifying one or more paths through a plurality of nodes. The show structure of nodes specifies the duration of any display,” but there is no durational requirement separate from the construction of “node.” See Ex. 1023, 2–13; Ex. 2003, 5; Prelim. Resp. 7–8. Third, we construe “interactively variable duration information,” which is recited in each of challenged independent claims 1, 23, and 26, as “a parameter specifying how long a content is to be displayed by default before a subsequent content is displayed, where the viewer of the content can change the parameter.” Ex. 1023, 22–23; Prelim.

Petitioner adds that “[s]uch a person could also have qualified with more formal education and less technical experience, or vice versa.” Id. (citing Ex. 1002 ¶¶ 13–18). Patent Owner proposes that a person of ordinary skill in the art “would have the equivalent of a four-year degree from an accredited institution (usually denoted as a B.S. degree) in computer science, computer engineering or the equivalent, and experience with, or exposure to, topics in computer networking, multimedia, and web systems. A person of ordinary skill in the art would also have approximately 3-5 years of professional experience with these topics.” Prelim. Resp. 5–6. In addition, Patent Owner say that “[a]dditional graduate education could substitute for professional experience, while significant experience in the field might substitute for formal education.” Id. Petitioner supports its proposal with testimony by Dr. Schmandt. See Ex. 1002 ¶ 16. Although the proposals differ in certain respects, they do not differ in ways that affect our decision to deny institution of the proceeding. See id. (Dr. Schmandt testifying that “Patent Owner’s proposed articulation is not meaningfully different” and that his “analysis, opinions and conclusions . . . would not change if Patent Owner’s articulation were applied”). Both proposals include baccalaureate degrees and experience in generally related fields, with both parties indicating that additional education or experience could compensate for some lack in the other. For purposes of this Decision, we adopt Petitioner’s proposal, which we find consistent with the level of skill reflected by the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.
