Inst. Dec. 7–8. Based on our consideration of the full record, we maintain our determination that a POSITA at the time the application for the ’802 patent was filed “would have had at least an undergraduate degree in pharmacy, chemistry, biochemistry, biomedical engineering or a closely related field, such that the POSITA generally understand[s] pharmaceutical formulation.” Pet. 12. Additionally, we agree with Petitioner that “[a] POSITA would be familiar with the chemical ingredients in the [’802] Patent, biocidic agents, and cationic agents, have knowledge of airborne particles including viruses and bacteria, and understand electrostatic fields, electrostatic attraction and repulsion, adhesion and cohesion.” Id.

Briefly, the preamble of independent claims 1, 2, and 8 limits the challenged claims as both the preamble and the body are used to define the subject matter claimed. See Allen Engineering Corp., v. Bartell Industries, Inc., 299 F.3d 1336, 1346 (Fed. Cir. 2002). In particular, the preamble is “necessary to give life, meaning and vitality” to the claim, see id., because it provides the only description in the claim for the application site of the formulation, i.e., “to skin or tissue of nasal passages,” and how the formulation is applied, i.e., “in a thin film.”” slip op. at 8

      “After consideration of the full trial record, we maintain our construction. From our perspective, the claims themselves support this construction as the claims expand upon the term “electrostatically inhibiting” with specific means for achieving such inhibition. Specifically, claims 1 and 2 recite electrostatically attracting the particulate matter, holding the matter in place, and inactivating the matter. Additionally, the Specification supports our construction as it describes the use of “an electrostatic field such that oppositely charged airborne particulates (including microorganisms) in the vicinity of the surface are electrostatically trapped, held thereto and one or more of the microorganisms so captured is neutralized, killed, inactivated, and rendered harmless.” Ex. 1001, 3:36–40; PO Resp. 10 n.6.” slip op. at 9

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for petitioner

      “We adopt the parties’ construction of “adequate impermeability” that has been accepted in the related district court litigation: “Adequate impermeability” refers to the “thin film holding harmful particles in place and inhibiting them from penetrating the thin film and contacting the skin or tissue of an individual’s nasal passages. This is done by varying the concentration of ingredients . . .[,] thereby adjusting the adhesion and cohesion of the thin film.” Pet. Reply 3 (quoting Ex. 1010, 17). Furthermore, as stated in our Institution Decision, along with that term, the claim language explains that the thin film is meant to stick to the skin or tissue and to hold the particulate matter in place. Inst. Dec. 9–10. The claim language also explains that the cohesion of the formulation is adjusted to provide adequate impermeability to the thin film. Thus, it is reasonable to consider the recited impermeability is a function of the cohesive properties of the thin film, and that such impermeability refers to a property of the thin film, i.e., inhibiting the penetration or passage of matter through it onto the skin or tissue at the application site.” slip op. at 10

See Ariad, 598 F.3d at 1350. Patent Owner concedes that the Specification does not describe a representative number of members of the genus, stating “this is a common structural features case.” Tr. 65:25–66:3.

      “However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent.

Petitioner argues that such a person of ordinary skill would also have at least three years of experience conducting research concerning endocrine disorders, including CAH or other adrenal disorders.

      “For these reasons, we do not find persuasive the testimony of Patent Owner’s expert, Dr. Dobs, that: By describing adjustments of dosing protocols to achieve at least a 10% reduction from baseline, and describing this use of tildacerfont as just one embodiment of the claimed use of the entire well-known, well-characterized, and discrete class, the specification reasonably conveyed to a POSA that the invention extended to the particularly claimed use of the entire recited class. Ex. 2014 ¶ 87. On the contrary, far from being a “well-known, well-characterized, and discrete class” the prior art teaches a heterogeneous assembly of different classes of small molecule CRF1 receptor antagonists (Type I, Type II, and “atypical”) displaying a very considerable variety of structures, both in terms of the core pharmacophore (e.g., monocyclic, bicyclic, tricyclic, phenolic, cyclohexyl amide, etc.) as well as in the various side groups. Moreover, the challenged claims recite only “a CRF1 receptor antagonist or a pharmaceutically acceptable salt thereof,” the scope of which also encompasses the much larger (and, according to Williams) much more effective large-molecule (peptide) CRF1 receptor antagonists, about which the Specification is entirely silent.

We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”). The specification of the ’202 patent further supports this finding: “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:22–24; see also Figs. 2A, 2B (showing interferer signals and desired signals together).” slip op. at 17

      “28 Because Petitioner has shown that asserted prior art references anticipate claims 1 and 3–10, we do not address whether these claims would have been obvious over De Oliveira, either alone or in view of Wiglesworth, Tobler, and Godoy. 29 Having determined that Petitioner has shown all challenged claims are unpatentable under other grounds, we do not address this obvious ground.

    • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportReference is prior artDecided for patent owner

      “Having considered the parties’ positions and evidence of record, summarized above, we agree with Patent Owner that Perkins is prior art to the ’366 patent only to the extent that the subject matter disclosed in Perkins is likewise described in the Perkins Provisional. Accordingly, we do not consider Petitioner’s arguments that rely on subject matter unsupported by the Perkins Provisional. For example, support for Petitioner’s argument that Perkins discloses “mutant VSV-G envelope protein containing only four mutations at N180, I182, T352, and E353” is not found in the Perkins Provisional and is therefore not considered. Pet. 73 (quoted with Petitioner’s emphasis). Thus, insofar as Petitioner is suggesting that Perkins describes a list of mutations that is narrowed to four positions including a mutation at I182, rather than a listing of thirteen potential positions for mutations (and various combinations thereof with hypothetical mutations at a variety positions), we find no such narrower listing in the Perkins Provisional. Compare Ex. 1005, 22:2–5, with Ex. 1006, 17–18.” slip op. at 19

      “genus even if the species are not themselves recited.” Bristol–Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1380 (Fed. Cir. 2001); see also, Atofina, 441 F.3d at 999 (“[A] very small genus can be a disclosure of each species within the genus.” (citing In re Petering, 301 F.2d at 682)). In Petering, for example, the prior art disclosed a small genus of only 20 compounds that included the claimed species. In re Petering, 301 F.2d at 682. In its discussion concluding that a small genus may anticipate a species of that genus, the Court of Customs and Patent Appeals explained that “it is not the mere number of compounds in this limited class which is significant here, but rather, the total circumstances involved, including such factors as the limited number of variations for R, only two alternatives for Y and Z, no alternatives for the other ring positions, and a large unchanging parent structural nucleus.” Id. at 681–682. Having considered the parties’ positions and evidence of record, summarized above, we do not find that Perkins discloses a limited class as exemplified in Petering. To begin, while it is undisputed that Perkins discloses a class of mutant VSV-G envelope proteins that encompasses the recited I182E or I182D mutations, it is also undisputed that Perkins does not disclose the I182E or I182D mutations. Prelim. Resp. 22. Furthermore, and by contrast to the limited class of compounds at issue in Petering, Perkins discloses a class of mutant VSV-G envelope proteins defined as proteins containing one or more of 20 possible mutations or alterations, a class that includes at least 254 proteins. Ex. 1006, 17–18; Prelim. Resp. 26–27. Furthermore, as Patent Owner correctly points out, “[t]he Perkins Provisional does not include any disclosure of the specific mutations to be made at any of these locations. That is, the Perkins Provisional does not indicate the other amino acid(s) to be substituted at the listed locations.” Prelim. Resp. 26. Thus, Perkins fails to provide a POSA with a “‘pattern of preferences’ that serves to narrow the genus.” See, e.g., Sanofi-Synthelabo v. Apotex, Inc., 470 F.3d 1368, 1377 (Fed. Cir. 2006) (“there is no such clear ‘pattern of preferences’ [as found in Petering] that serves to narrow the genus in claim 2 to a narrow class that includes clopidogrel bisulfate”).” slip op. at 22

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

      “Obviousness is a question of law based on underlying findings of fact.” In re Kubin, 561 F.3d 1351, 1355 (Fed. Cir. 2009). A conclusion of obviousness is appropriate where the prior art “contain[s] detailed enabling methodology for practicing the claimed invention, a suggestion to modify the prior art to practice the claimed invention, and evidence suggesting that it would be successful.” In re O’Farrell, 853 F.2d 894, 902 (Fed. Cir. 1988); see also, In re Kubin, 561 F.3d at 1359 (KSR “actually resurrects [the Federal Circuit]’s own wisdom in In re O’Farrell”). However, to render a claim obvious, prior art cannot be “vague” and must collectively, although not explicitly, guide an artisan of ordinary skill towards a particular solution. Bayer Schering Pharma AG v. Barr Labs., Inc., 575 F.3d 1341, 1347 (Fed. Cir. 2009). That is, when a field is “unreduced by direction of the prior art,” and when prior art gives “no indication of which parameters were critical or no direction as to which of many possible choices is likely to be successful,” an invention is not obvious. Bayer Schering, 575 F.3d at 1347 (citing In re O’Farrell, 853 F.2d at 903). Having considered the parties’ positions and evidence of record, summarized above, we are not persuaded that Perkins discloses a finite set or limited class of 19 mutations. Pet. 66. Rather, we agree with Patent Owner that Perkins discloses a large genus of mutant VSV-G polypeptides containing at least 254 species—“Perkins Provisional discloses mutations at I182 among a group of 20 other possible locations for modifications[,] . . . [13] of these 20 positions are specific amino acids that . . . can be changed to any of the 19 other natural amino acids” —each species combinable to create a vast number of species. Prelim. Resp. 32. Perkins does not indicate any preference among the 13 disclosed mutations, does not indicate any preference among the 19 other amino acids, and does not indicate any preference as to which mutations should be combined to successful effect. Ex. 1006, 17–18. Thus, while Perkins discloses that one or more mutations “inhibit the envelope protein’s ability to bind its native target, while preserving the envelope protein’s fusogenic properties,” beyond that, a POSA would have no direction for selecting the route to create the I182E or I182D mutations specified by the challenged claims among the various unpredictable alternatives suggested by Perkins. Ex. 1006 at 16; Ex. 1002 ¶ 193. We do not find this to be the easily traversed, small or finite number of alternatives that KSR suggested might support an inference of obviousness.

      “packetize” or “packetizing” as recited in claims 2, 9, and 14. PO Resp. 19– 20; Pet. Reply 5–6. Patent Owner argues that we should construe “packetize” to mean “create data packets that include destination information.” PO Resp. 19–20. Patent Owner argues that this is consistent with how the Board previously interpreted this claim term in the 00571 IPR. PO Resp. 19 (citing Ex. 1017). We do not need to construe “packetizing” because collateral estoppel prevents Patent Owner from arguing that Wu does not disclose “packetizing” as explained below. We also do not need to construe any other terms to resolve the disputes before us. Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “When deciding whether issue preclusion applies, we consider whether: (1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party. VirnetX Inc. v Apple, Inc., 909 F.3d 1375, 1377 (Fed. Cir. 2018) (citing Stephen Slesinger, Inc. v. Disney Enterprises, Inc., 702 F.3d 640, 644 (Fed. Cir. 2012)). To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet. Reply 24; Ex. 1017, 31–34 (final written decision determining obviousness of claims 9, 10, 14, and 16 of the ’473 patent over Wu and Sabat-426); Ex. 1072, 5 (summarizing the final written decision regarding the packetizing limitations), 10–16 (finding no error in the determinations regarding the packetizing limitations).” slip op. at 12
