      “To satisfy written description for the claimed genus of iBTKIs, the Specification must describe either a representative number of members of the genus or structural features common to the members of the genus with enough precision that a POSA can visualize or recognize the members of the genus. 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.

Pet. 60 (citing Ex. 1005 ¶ 34). 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. Id. Patent Owner does not expressly contest this definition of a person of ordinary skill in the art in its Response. Because we find Petitioner’s definition to be consistent with the demonstrable level of skill in the art (see, e.g., Exs. 1009, 1025, 2003, 2004, 2005), and in the absence of a different proposed definition of the level of skill in the art by Patent Owner, we adopt Petitioner’s definition.” slip op. at 26

      “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.

      “Patent Owner “agrees that the preamble is limiting as a statement of the intentional purpose for which the method is performed—treating patients with CLL or SLL.” Prelim. Resp. 18. But Patent Owner disagrees with an “attempt to rewrite an express definition in the specification” and adds a safety requirement that is not recited in the definition of “therapeutically effective amount” in the Specification. Id. at 19. Patent Owner contends “therapeutically effective amount” should be construed according to its express definition in the Specification to mean “a sufficient amount of an agent or a compound being administered which will relieve to some extent one or more of the symptoms [of a] B-cell lymphoproliferative disorder (BCLD) . . . [or] reduction and/or alleviation of the signs, symptoms, or causes of BCLD.” Id. (citing Ex. 1001, 24:58–63). Notwithstanding its proposed construction, Patent Owner posits that “a precise construction of ‘therapeutically effective amount’ is not necessary to resolve the dispute here” and “[e]ven under Petitioner’s flawed construction of ‘therapeutically effective amount,’ Petitioner fails to meet its burden to warrant institution.” Id. at 20. Having considered the parties’ respective arguments at this stage of the proceeding, we agree that the preamble is limiting as a statement of intentional purpose. See Eli Lilly & Co. v. Teva Pharms.

Moreover, we find Patent Owner has the better position that the term “therapeutically effective amount” should be construed according to its express definition in the Specification and not according to the separate and distinct definition of “effective amount,” as Petitioner suggests. That is, we decline to import a safety limitation to the term “therapeutically effective amount” that only appears in the definition for “effective amount.” Compare Ex. 1001, 24:58–62 with id. at 24:66–25:2” slip op. at 8

      “Level of Ordinary Skill in the Art In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995). Furthermore, the prior art itself can reflect the appropriate level of ordinary skill in the art. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Here, Petitioner asserts that an ordinarily skilled artisan “would typically have an advanced degree, such as a Ph.D., with research experience in genomics, molecular biology, bioinformatics, or a related field, or could have less education but significant professional experience in one or more of these fields.” Pet. 8–9 (citing Ex. 1002 ¶ 38). Patent Owner states that for the purposes of this proceeding, it does not dispute Petitioner’s definition of the skill level. PO Resp. 2 (citing Ex. 2023 ¶¶ 21, 22).

      “1. “Sequence Reads” Petitioner argues that, for purposes of this Decision, no claim term needs specific construction beyond its plain and ordinary meaning. Pet. 10–11. Petitioner, however, seeks to provide context for understanding the scope of the term “sequence reads.” Specifically, Petitioner contends that “sequence reads” are produced by sequencing at least some of the tagged strands, whereas “consensus sequences” are generated by collapsing sequence reads. Id. at 11 (citing Ex. 1001, 4:45–47, 20:50–22:25, 23:29–57, 24:46–48, claim 1, claim 6). In the Decision to Institute, we agreed with Petitioner that “[t]he claims of the ’951 patent as well as the specification make clear that a ‘sequence read’ is different and distinct from a ‘consensus sequence.’” DI 7 (quoting Pet. 11). Patent Owner does not dispute Petitioner’s assertion. PO Resp. 12.

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

      “We disagree with Patent Owner’s proposed construction of the terms “paired sequence reads” and “unpaired sequence reads.” Even though the ’951 patent Specification discloses grouping sequence reads “sharing a unique set of SMI tags” into paired families,4 “[t]he written description part of the specification itself does not delimit the right to exclude. That is the function and purpose of claims.” Phillips, 415 F.3d at 1312 (“[T]he claims of a patent define the invention to which the patentee is entitled the right to exclude.”). Here, claim 1 explicitly defines the terms “paired sequence reads” and “unpaired sequence reads.” Indeed, in the context of paired versus unpaired sequence reads, claim 1 specifies that the complementarity is related to the “original parent polynucleotide molecule,” and not the duplex tags. For example, claim 1 recites that “each unpaired read represents a first tagged strand having no second differently tagged complementary strand derived from an original parent polynucleotide molecule represented among said sequence reads in said set of sequence reads.” Ex. 1001, 37:50–55 (emphasis added). Thus, the plain claim language contradicts Patent Owner’s argument” slip op. at 11

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateDecided for petitioner

      “Claim 1 defines the terms “paired sequence reads” and “unpaired sequence reads” based on the complementarity of the target sequence strands derived from the “original parent polynucleotide molecule.” Ex. 1001, 37:46–55. As explained above, we reject Patent Owner’s contention that a sequence read is considered unpaired solely based on the complementarity of the SMI tags. See supra Section II.C.2. Due to the “errors introduced during sample preparation and sequencing” (Ex. 1029 ¶ 5), there are four outcomes when determining the complementarity of the sequence reads of two strands of SMI-linked target sequence: (1) the first SMI tag and the first strand target sequence are complementary to the second SMI tag and the second strand target sequence, respectively; (2) the first SMI tag is complementary to the second SMI tag but the first strand target sequence is not complementary to the second strand target sequence; (3) the first SMI tag is not complementary to the second SMI tag but the first strand target sequence is complementary to the second strand target sequence; and (4) the first SMI tag is not complementary to the second SMI tag, and the first strand target sequence is not complementary to the second strand target sequence. It is undisputed that Schmitt groups sequence reads into paired families based on the SMI tags, and Schmitt only considers sequences in which “information from both DNA strands was in perfect agreement.” Ex. 1029 ¶¶ 14, 96; PO Resp. 18. Thus, among the four outcomes, only scenario (1), in which both the SMI tags and the target sequences are complementary, represents a “paired sequence read,” which claim 1 defines as corresponding to “sequence reads generated from a first tagged strand and a second differently tagged complementary strand derived from an original parent polynucleotide molecule.” Ex. 1001, 37:46–50.

      “Independent claim 1 recites a method of treating CAH by reducing an A4 level “from baseline” after administering a CRF1 receptor antagonist to a CAH patient. See Ex. 1001, 47:51–48:5. The Specification expressly teaches that, with respect to the clinical phase 2 trial described in Example 4, “Patients will have overnight [pharmacokinetic/pharmacodynamics] PK/PD assessments performed at baseline, which include an [sic] pre-dose overnight assessment and a post-dose overnight assessment for PK/PD following administration of the first dose.” Ex. 1001, 41:55–59. This is the same quotation and clinical trial relied upon by Dr. Barnes in his Declaration, and is the only definition of a “baseline” in the ’201 patent. See Ex. 1037, 36–37. We note that placebos were evidently not employed in the phase 2 clinical study of Example 4.5 Given the sole exemplary description of “baseline” in Example 4 of the Specification, we construe the claim term reciting “reduced from baseline” as meaning “a reduction in A4 level compared to an A4 level measurement made prior to, and/or at the beginning of, administration of the drug.”” slip op. at 10

Because Petitioner’s definition of a person of skill in the art appears commensurate with the level of skill reflected in the asserted art in this case, as well as the ’463 patent itself, we apply Petitioner’s proposed level of ordinary skill in the art to determine whether it is more likely than not that Petitioner would prevail with respect to at least one of the claims challenged in the Petition.

      “When claim 1 is read in light of the Specification of the ’463 patent, we find that Petitioner’s construction is too expansive and not commensurate with the appropriate scope of claim 1 when the Specification of the ’463 patent is considered. As the Specification of the ’463 patent makes clear, indaziflam has been in use as an herbicide and is well-characterized. See Ex. 1001, 3:17–6:6. The Specification of the ’463 patent incorporates by reference U.S. Patent No. 8,114,991, which describes indaziflam, and the Specification of the ’463 patent also describes several commercially available herbicides incorporating indaziflam as their active ingredient. See id. at 3:22–27, 4:15–41. The Specification of the ’463 patent sets forth embodiments with specific ranges for the amount of indaziflam. See id. at 5:45–6:6. Finally, the Specification of the ’463 patent states: A person having ordinary skill in the art would understand how to adjust dosages and concentrations depending on whether the composition is to be applied to a desirable plant or seed, part or habitat thereof, or directly to a site in which no desirable plants are present or growing (e.g., a monoculture of unwanted annual grass).” slip op. at 11

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITANo construction needed

      “We find that Petitioner’s expansive construction of the claim phrase “a composition comprising a cellulose biosynthesis inhibitor” to be inconsistent with the meaning of the transitional phrase “comprising” within the context of the claim as a whole and also inconsistent with the teachings set forth in the Specification of the ’463 patent. The transitional phrase “comprising” is inclusive or open-ended and should be read to not exclude additional, unrecited elements or method steps. See, e.g., Invitrogen Corp. v. Biocrest Mfg., L.P., 327 F.3d 1364, 1368 (Fed. Cir. 2003) (“The transition ‘comprising’ in a method claim indicates that the claim is open-ended and allows for additional steps.”); Genentech, Inc. v. Chiron Corp., 112 F.3d 495, 501 (Fed. Cir. 1997) (“Comprising” is a term of art used in claim language which means that the named elements are essential, but other elements may be added and still form a construct within the scope of the claim.”) (citing In re Baxter, 656 F.2d 679, 686 (CCPA 1981). Therefore, although the term “comprising” does not exclude additional steps or elements, that does not mean that any other step or element may or should be added, such as any other chemical, as Petitioner asserts. The Specification of the ’463 patent contemplates using indaziflam as the herbicidally active ingredient, but also contemplates the addition of other active ingredients in the composition. Ex. 1001, 5:59–65; 6:7–11. The Specification of the ’463 patent also contemplates the addition of other ingredients in the composition as well. Specifically, the Specification states: These formulations are produced in any desired or known manner, for example by mixing the active compounds with extenders, such as liquid solvents, pressurized liquefied gases and/or solid carriers, optionally with the use of surface-active agents, such as emulsifiers and/or dispersants and/or foam formers. Id. at 17:6–11. This and the remainder of the Specification does not suggest the expansive interpretation of the claim limitation argued by Petitioner. For example, the Specification explains that the point of the invention is to treat vegetation that is or will be consumed by livestock animals, and, more specifically, that such animals will provide food (e.g., milk or meat) for others (e.g., people or pets) further up the food chain. Id. at 2:31–35, 2:39– 59. Reason and the evidence of record support that such goals are not commensurate with co-applying any chemical in any amount to the same area.

      “3. Effective Filing Date of the Challenged Claims In an IPR, although Petitioner has the ultimate burden of persuasion to prove unpatentability, Patent Owner must demonstrate entitlement to a priority date when Patent Owner relies on that priority date to overcome an anticipation or obviousness argument. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1379–80 (Fed. Cir. 2015); see also In re NTP, Inc., 654 F.3d 1268, 1276 (Fed. Cir. 2011) (“[A] patent’s claims are not entitled to an earlier priority date because the patentee claims priority. Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120.” (citations omitted)). On the current record, and for purposes of this Decision, we find Patent Owner has not shown sufficiently that the claims of the ’951 patent are entitled to an effective filing date earlier than July 26, 2017, the filing date of the ’785 application. Thus, Eltoukhy qualifies as prior art. See Pet. 13–34. For this analysis, we focus on step (d) of claim 1, “sorting sequence reads into paired sequence reads and unpaired sequence reads” (“the sorting limitation”).” slip op. at 11

      “Ex. 1006, 1 (citations omitted). Accordingly, when considering the ’507 patent’s purpose, the type of problems encountered in the art, and prior art solutions to those problems, it is clear that with respect to levodopa/carbidopa treatments for Parkinson’s Disease, the pharmaceutical formulation and its resulting pharmacokinetics and patient experience are intertwined, thus supporting a requirement that a person of ordinary skill in the art have knowledge or experience in each of these areas. See, e.g., Indivior Inc. v. Dr. Reddy’s Labs., S.A., 930 F.3d 1325, 1345 (Fed. Cir. 2019) (finding no clear error in district court’s compromise measure of level of ordinary skill in the art as a team comprising different skill sets). In view of the above considerations, we preliminarily find that a person of ordinary skill in the art would be a member of a team that includes person(s) with (a) a Ph.D. in a field related to the development of pharmaceuticals (for example, pharmacology, pharmacokinetics, pharmaceutics, pharmaceutical chemistry, organic chemistry, biochemistry, molecular biology, medicinal chemistry, formulation development, or a related field), or equivalent degree, and 2–4 years of experience in the analysis of pharmacokinetic data, pharmaceutical formulation development, and/or drug discovery or development, or a B.S. or M.S. degree in a field related to the development of pharmaceuticals, or equivalent degree, and 4–6 years of experience in the analysis of pharmacokinetic data, pharmaceutical formulation development, and/or drug discovery or development, and (b) a medical degree or equivalent degree with experience in treating patients with Parkinson’s disease. In subsequent briefing, should the parties propose any differences from the team approach articulated above, they should support their proposal and address the impact, if any, of the differences on the pertinent disputes in this proceeding.

Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). An adequate description does not require any particular form of disclosure or that the specification recite the claimed invention in haec verba, but must do more than render the claimed invention obvious. Id. at 1352. In evaluating the adequacy of the disclosure, a court may consider “the existing knowledge in the particular field, the extent and content of the prior art, the maturity of the science or technology, [and] the predictability of the aspect at issue.” Capon v. Eshhar, 418 F.3d 1349, 1359 (Fed. Cir. 2005) (cited with approval in Ariad, 598 F.3d at 1352); see also Boston Sci. Corp. v. Johnson & Johnson, 647 F.3d 1353, 1366 (Fed.

Telectronics, Inc., 857 F.2d 778, 785 (Fed.

Calgene, Inc., 188 F.3d 1362, 1371 (Fed.
