      “Paper 34, 1 (requesting “Director Review of the Director’s August 22, 2025 Decision Referring the Petition to the Board (‘Referral Decision’)”). Patent Owner argued that institution of IPR2025-00687 and IPR2025-00688 “should be discretionarily denied.” Id. at 5. Petitioner opposed. Paper 37. The Director granted review and found that “granting institution of two petitions that each challenge the same claims of the ’370 patent and ’218 patent 2” was an “abuse[] of discretion.” Paper 40, 1. The Director remanded the cases “to the Board panel to determine which of the two petitions challenging each of the ’370 and ’218 patents to institute.” Id. at 3. Pursuant to the Director’s instruction that we choose only one of the two petitions challenging the ’370 patent to institute, and for the reasons set forth below, we choose to institute review of the ’370 patent in this Petition, and not in IPR2025-00688.” slip op. at 3

      “We agree with Patent Owner and credit Dr. Davies’s testimony (Ex. 2024 ¶¶ 210–215) that a POSA would not have expected the Glu3 substitution to produce such a result. Indeed, the premise for Petitioner’s “conservative substitution” rationale is that the Glu3 substitution would have been expected to produce an analog having similar properties to human uroguanylin. See, e.g., Pet. 1, 36 (stating that a POSA “would have expected this particular conservative substitution to retain excellent receptor-activating activity”); Reply 3 (urging that the reason to modify a known compound may be an expectation that the new compound will have “similar properties to the old”) (internal quotations omitted). Patent Owner’s HPLC data, however, demonstrate a difference in kind between the data for SP-304 (a single HPLC peak) and uroguanylin (two distinct peaks corresponding to the active and inactive topoisomer) after incubation under the same conditions. As Dr. Davies explains, “topoisomers exist as a mixture of compounds with different[] spatial conformations” that are “continuously interconverting between spatial conformations” with “varying degrees of interconversion stability.” See Ex. 2024 ¶¶ 51–56. Thus, Patent Owner’s data show that the Glu3 substitution results in a peptide that is demonstrably more stable against interconversion than the parent, unmodified peptide.” slip op. at 35

      “We find Patent Owner’s evidence persuasive to show that the Glu3 substitution results in an unexpected improvement in interconversion stability. As explained above, RP-HPLC was a known technique for separating the topoisomers of human uroguanylin. Ex. 2010, 230–231; Ex. 2011, 27–28; Ex. 2020, 223; Ex. 2028, TRUL00018269; see also Ex. 1063 ¶¶ 37, 40 (Petitioner’s expert confirming same). It was also known that one of human uroguanylin’s topoisomers was biologically active, whereas the other, i.e., what we and the parties refer to as the “inactive” topoisomer, had significantly less or no activity at the same concentration. Ex. 2011, 31 (“compound I shows significant activity in the cGMP producing assay, whereas compound II is practically inactive”); see also Ex. 2010, 238–239 (Fig. 8) (showing the “A isomer” had a potency “with a minimal concentration between 10-7and 10-8 M,” but that the B isomer “had virtually no effect on cGMP level at 10-6 M”); Ex. 2074, 48 (compound II “showed maximal 10% of the activity of compound I at 10-6 M”). The chromatograph for uroguanylin in Patent Owner’s data is consistent with these teachings, showing two peaks representing the active and inactive topoisomers. Compare Ex. 2028, TRUL00018269 (Fig. 1) with Ex. 2011, 28 (Fig. 2). The chromatograph for SP-304 shows a markedly different result, i.e., a “single peak,” which was confirmed “using the cGMP T84 cell assay” to represent “the fully active conformer of SP-304.” Ex. 2028, TRUL00018269; Ex. 2024 ¶¶ 208–209. We agree with Patent Owner and credit Dr. Davies’s testimony (Ex. 2024 ¶¶ 210–215) that a POSA would not have expected the Glu3 substitution to produce such a result.

First, the Court stated we “should determine, based on the evidence put forward by the parties, whether plecanatide exhibits topoisomerism and whether the testing of the challenged claims should encompass both the active and inactive forms.” Id. at 12.3 Second, the Court instructed us to reconsider what the closest prior art compound is in view of Patent Owner’s “contention that highly pure A-form uroguanylin could be maintained as a lyophilized powder,” noting that “[i]f it is true . . . that uroguanylin can be maintained and therefore tested in its active A form as a lyophilized powder, that would support that the experiments [which were conducted in solution] did not use the closest prior art.” Id.

      “In sum, we find that there is a sufficient nexus between Patent Owner’s results and the challenged claims and that those results are reasonably commensurate with the same. Accordingly, for all of reasons explained above, the unexpected results Patent Owner relies upon are probative of non-obviousness. E. Conclusion for Ground 1 Weighing the record as a whole in view of the findings and analysis above as well as our findings and analysis relating to Petitioner’s prima facie showing in the Decision, we conclude that Petitioner has not met its burden to show that claim 1 would have been obvious over Currie and Li. The evidence suggesting that it would have been obvious to make the Glu3 substitution because it is a conservative substitution (see Dec. 20–38 (§ III.E.ii)) is substantially outweighed by Patent Owner’s comparatively strong evidence demonstrating unexpected results relating to improved interconversion stability, potency, and binding affinity from the Glu3 substitution. See Millennium Pharms., Inc. v. Sandoz Inc., 862 F.3d 1356, 1368 (Fed. Cir. 2017) (“Evidence of objective indicia [such as unexpected results] ‘can be the most probative evidence of nonobviousness in the record,’ and . . . enable[s] ‘the court to avert the trap of hindsight.’”) (quoting Leo Pharm. Prods., Ltd. v. Rea, 726 F.3d 1346, 1358 (Fed. Cir. 2013). Indeed, the interconversion and potency categories of Patent Owner’s unexpected results showing are particularly strong such that even without the additional results in Liu, we would still reach the same ultimate conclusion on obviousness. Accordingly, Petitioner has not shown by a preponderance of the evidence that claim 1 is unpatentable.” slip op. at 56

      “We agree with Petitioner that the above-quoted paragraph of Wouters teaches “combining . . . correct working codes from the scanned remote control code-sets into a new custom configuration code set” using Wouters’s “fixer,” which combines the codes into a custom codeset, gives it a name, such as “user1,” and stores it in a memory (the “RC code set data base”). See Pet. Reply 2; Ex. 1009, 10:18–20. This custom codeset includes a combination of the working codes previously tested and installed by the user. Ex. 1009, 10:18–20. We also find that the above-quoted paragraph of Wouters teaches “installing . . . the combined correct working codes of the new custom configuration code set for use by the remote control.” Specifically, Wouters teaches that, when the remote control’s batteries die, “the user may easily reinstall the chosen code set by choosing ‘user1’ from the proposed list or immediately selecting ‘user1.’” Ex. 1009, 10:20–22 (emphasis added). This reinstallation is of the combined correct working codes of a new custom configuration codeset previously stored and named by the fixer, such as the “user1” codeset. Id. at 10:20–24. We find that Wouters’s “reinstallation” of the chosen code set (e.g., the “user1” codeset) is an “installation” of that codeset. The claim merely recites “installing” the codeset, and does not distinguish between an initial installation and a re-installation, such as after the batteries of the remote control die. Ex. 1001, 10:45. Patent Owner also does not point to anything in the ’875 patent Specification or the other intrinsic evidence that would limit the “installing” in limitation 11[e] to an initial installation, or that would exclude a re-installation after the remote control’s batteries die. Consequently, we find that Wouters’s reinstallation of the codeset after the batteries die is an “install[ation]” as required by limitation 11[e].

We find that Wouters’s “reinstallation” of the chosen code set (e.g., the “user1” codeset) is an “installation” of that codeset. The claim merely recites “installing” the codeset, and does not distinguish between an initial installation and a re-installation, such as after the batteries of the remote control die. Ex. 1001, 10:45. Patent Owner also does not point to anything in the ’875 patent Specification or the other intrinsic evidence that would limit the “installing” in limitation 11[e] to an initial installation, or that would exclude a re-installation after the remote control’s batteries die. Consequently, we find that Wouters’s reinstallation of the codeset after the batteries die is an “install[ation]” as required by limitation 11[e]. We further agree with Petitioner that the Wouters-Verzulli combination discloses that these operations would be performed using a processor and memory, which Patent Owner does not appear to dispute.

      “The Federal Circuit vacated the Board’s determination as to claims 6, 8, 11, and 17 and remanded to the Board to address Petitioner’s motivationto-combine arguments for Cooper and Baldwin in view of the Board’s finding that Cooper does not teach limitation 1[d], and to address whether Cooper teaches the additional limitations of claims 6, 8, 11, and 17. See Fed. Cir. Dec. 10. The Federal Circuit faulted the Board’s conclusion as failing to provide substantive analysis of Petitioner’s motivation to combine arguments. See id. at 8. In particular, the court explained that Petitioner provided a detailed explanation of why a person of ordinary skill in the art would have been motivated to combine Cooper’s receiver teachings with Baldwin’s teachings of providing alternative streams with staggered access points and selecting the stream with the next available access point. See id. at 8–9. The court highlighted Petitioner’s following arguments: (1) a person of ordinary skill in the art would have combined the prior art according to known methods to yield predictable results; (2) combining the prior art would have been a simple substitution of one known element for another to obtain predictable results; and (3) the combination represents a choice from a finite number of identified predictable solutions with a reasonable expectation of success. See id. at 9. Accordingly, the issues before us are whether a person of ordinary skill in the art would have been motivated to combine the teachings of Cooper and Baldwin and whether Cooper teaches the additional limitations of dependent claims 6, 8, 11, and 17. See Fed. Cir. Dec. 8–10. To provide the full context for the issues before us, we first address each of the limitations of independent claims 1 and 12, and Petitioner’s reasons for combining the teachings of Cooper and Baldwin, followed by an analysis of the limitations of dependent claims 6, 8, 11, and 17.” slip op. at 8

      “We agree with Petitioner. Lemay Web discloses that the style settings of width, height, pause, and repeat for the pocket watch images can be changed by changing the values for width, height, pause, and repeat in the HTML file. Ex. 1004, 89–90. This results in changing the size, duration, and frequency of the display of the multiple pocket watch image objects without changing the image files or the Java applet. Id. That is, the 12 image objects of Lemay Web can be uniformly formatted by applying and altering the style settings of the HTML file, which is stored separately from the image objects and the Java applet. Id. at 88– 89. In our Final Written Decision, we wrote that “Lemay Web discloses that the image files that are displayed as the animation object are separate from the HTML.” Ex. 1004, 88–89.” Dec. 22. The Federal Circuit wrote that “how the Board evaluated what constitutes separateness in the prior art software is less than clear.” Opinion, 13 n.7. To be clear, the animation of Lemay Web comprises 12 different pocket watch image objects. Ex. 1004, 89. The HTML file that contains the style settings for the 12 different pocket watch image objects is stored separately from the 12 different pocket watch image objects. Id. at 88–91. The style of the 12 different pocket watch image objects can be altered by changing the values of the style settings in the separate HTML file, thus allowing the style to be uniformly applied to each of the associated 12 pocket watch image objects when the pocket watch image objects are created on the web page. Id.; see Ex. 1030 ¶¶ 28–29; Dec. 21–22. In conclusion for issue (B), we find that Lemay Web teaches applying the style located in the separate HTML file to the pocket watch image objects when creating the pocket watch image objects on the web page. Therefore, Lemay Web’s style is “defined separately from any single object” as claimed. Because Lemay Web’s style can be applied to one object and more than one object and Lemay Web’s style is defined separately from any single object, we find that the prior art combination teaches limitations 1(c) and 1(g) under the proper construction of “style.”” slip op. at 12

      “What you see in the bottom right is an excerpt from the Lemay Web book . . . [y]ou can still use the Java applet just by putting this applet code into your HTML file. So this shows the animator class is going to be run within height or how big a window within the browser should be allocated in this applet. You can . . . tell the animator class how long to pause in between each image. So that’s a style that’s being applied to all of the multiple images that make up this animation. Ex. 2029, 746:23–747:7. Patent Owner then asked GoDaddy’s expert “for each unique animation you want to create with this animator class that’s shown here, you’re going to have to have a unique set of HTML code with the settings along with any of the images you’ll want to associate with the animator class, right?” Ex. 2030, 793:7–11. GoDaddy’s expert testified, with reference to Exhibit 2027, 80, that “Yeah. I’m not a hundred percent sure I understand your question, but yes, if you had six animations on a page, for example, you’d have six blocks of markup that looked like the markup at the bottom right of that slide, starting with applet.” Id. at 793:12–16. In addressing Patent Owner’s question about “each unique animation,” GoDaddy’s expert provided a hypothetical example of a web page having six animations, and explained that the six animations have six blocks of markup. Ex. 2030, 793:13–16. We find that this testimony means that if a web page has six unique animations, then for each unique animation, a corresponding HTML file contains the style settings for the image objects of that animation, such that the “six animations on a page . . . have six blocks of markup.” Id. We find that the subsequent testimony of GoDaddy’s expert cited by Patent Owner is consistent with the expert’s initial testimony that Lemay Web’s style is “applied to all of the multiple images that make up this animation.” Ex. 2029, 747:5–7. We also find that the subsequent testimony is consistent with and supported by the disclosure of Lemay Web, which teaches that an animation has a set of image files and is added to a Web page using the Animator applet. Ex. 1004, 88 (“[Y]ou’ll learn just enough about Java applets to set up animation on your Web page. . . . To create animation using Java and the Animator applet, you’ll need . . . [a] set of image files . . . that make up your animation.”); see id. at 88–91. That is, Lemay Web, consistent with the testimony of GoDaddy’s expert, discloses that the style settings for the animation of the pocket watch in the HTML file are uniformly applied to the 12 pocket watch image objects.
