“However, we prefer Patent Owner’s definition of the required 2–3 years of experience in “the development and syntheses of nucleosides, nucleotides, and nucleic acids, including, but not limited to, the syntheses of oligonucleotides through solid phase oligonucleotide synthesis (‘SPOS’)” to Petitioner’s more generalized requirement of having experience in “medicinal chemistry, synthetic organic chemistry, and nucleic acid chemistry, including the development of oligonucleotide therapeutics, diagnostics, or building blocks.” Both parties acknowledge that the level of skill in the art is very high. See, e.g., Resp. 17; Reply 2. We find that, to achieve a level of ordinary skill in the art, a person with the requisite educational background would require 2–3 years of experience for one possessing a doctorate in the relevant field, or 3–5 years for one with a lesser degree (to compensate for the additional educational experience gained by achieving a doctorate) in the specific techniques recited by Patent Owner. We reject the terminal clause “pursuant to P(III) chemistry” proposed by Patent Owner as redundant in that a person engaged for a number of years in “the development and syntheses of nucleosides, nucleotides, and nucleic acids” including SPOS, would likely have an operant knowledge of P(III) chemistry. Consequently we adopt the following definition of a person of ordinary skill in the art: “A person of ordinary skill in the art having a Ph.D. (or equivalent degree) in organic or medicinal chemistry, and 2 to 3 years of post-graduate work experience in the development and syntheses of nucleosides, nucleotides, and nucleic acids, including, but not limited to, the syntheses of oligonucleotides through solid phase oligonucleotide synthesis (‘SPOS’)” and, alternatively, “a person of ordinary skill in the art would have a Bachelor’s or Master’s degree in organic or medicinal chemistry who had at least 5 years of extensive work experience in these fields.”” slip op. at 12

“As for Dr. Baran, we are not persuaded by Patent Owner’s argument that Dr. Baran is not sufficiently experienced or qualified to opine with respect to the claimed subject matter. A review of Dr. Baran’s extensive curriculum vitae (Ex. 1003, 79–137), indicates that he is deeply experienced and extensively published in the field of oligonucleotide synthesis. Patent Owner’s argument that Dr. Baran is principally experienced in P(V) techniques presupposes that experience in that technique indicates an ignorance of P(III) methodologies. We do not find this position consistent with the breadth of Dr. Baran’s C.V. We will weigh Dr. Baran’s testimony, and that of Dr. Hrdlicka, against the cumulative weight of the evidence of record in this inter partes review in assessing the credibility and probative value of their respective testimonies.” slip op. at 13

“Furthermore, both Petitioner and Patent Owner agree that clear errors exist in the wording of challenged claims 3–5. Both parties agree that a person of ordinary skill in the art would have recognized that the limitation reciting “where M is selected from the group consisting of succinyl, oxalyl, and hydroquinolynyl” should properly read “where M is selected from the group consisting of ethyl, oxalyl, and hydroquinolynyl.” Pet. 18–20; PO Resp. 15. Both parties further agree that the language of claim 5 mistakenly omits the italicized portions of the limitation reciting “NH is capable of being attached to a solid support with a spacer selected from the group consisting of C1–C20 alkyl, ethyloxyglycol, and a combination of alkyl and ethyleneglycoxy,” as is expressly recited in claims 3 and 4. Pet. 21–22 (citing Ex. 1003 ¶ 158); PO Resp. 15. We agree with both parties’ reasoning with respect to these errors, and we construe the claims as reciting the corrected language, such that claims 3–5 read, in relevant part “where M is selected from the group consisting of ethyl, oxalyl, and hydroquinolynyl” and claim 5 additionally reads “NH is capable of being attached to a solid support with a spacer selected from the group consisting of C1–C20 alkyl, ethyloxyglycol, and a combination of alkyl and ethyleneglycoxy.” See Fitbit, Inc. v.

“For claim 1, Petitioner asserts that, if Govier does not disclose applying an electrode patch to the outer surface of the skin, skilled artisans would have had reason to substitute Williams’s known electrode patch for Govier’s ground pad as a simple substitution of one known structure for another performing the same function—“creating a current path along the tibial nerve”—and yielding the same results—“ability to stimulate the tibial nerve to treat overactive bladder.” Id. at 21–24. Petitioner contends also that, if Govier does not disclose a controller including a pulse generator, skilled artisans would have had reason “to substitute Williams’s pulse generator for Govier’s stimulator.” Id. at 27–29.

“Finally, we are reminded that “a sufficient description of the genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350. “[F]unctional claim language can meet the written description requirement when the art has established a correlation between structure and function.” Id. Here, however, the challenged claims are directed to methods using a wide range of different types of compounds purported to be “IL-15/IL-15R inhibitors” that are not part of a known or readily identifiable class, do not target the same biological pathway, do not have any common structural features, and do not appear to always function as inhibitors. See Ex. 1018, Abstr., 1575–77, 1579; Ex. 1046, 189:4–19, 191:15–192:15, 193:18–196:22, 198:21–199:21, 197:12–198:19, 200:1–8, 207:11–14, 203:3–10, 207:15–21, 236:12–24; Ex. 1047 ¶¶ 19–23, 56, 63–64, 80–85.

“598 U.S. at 610. A “specification may call for a reasonable amount of experimentation to make and use a patented invention. What is reasonable in any case will depend on the nature of the invention and the underlying art.” Id. at 613. But the person of ordinary skill in the art cannot be left with merely “a hunting license” or obligated to engage in “painstaking experimentation” or “trial and error” to “see what works.” Id. at 614. Patent Owner argues that “the IL-15/IL-15R inhibitors disclosed in the specification were known in the art and “share the common ‘general quality’ of inhibiting a pathway known to be relevant to and having ‘particular fitness for the particular purposes’ of (id.) treating certain autoimmune diseases by blocking IL-15 signaling.” Sur-reply 14 (citing Ex. 1011, 22; Ex. 2013, 3; Ex. 2017, Abstr.; Ex. 2024, 17; Ex. 2025, 2–3, 6; Ex. 2027, 4; Ex. 2028, 9; Ex. 2029, 4; Ex. 2031, 23; Ex. 2118, 53:22–54:9; Ex. 1018, 1; Ex. 2005, ¶¶ 52–63, 80–83, 130; Ex. 1046, 231:20–25). Patent Owner’s argument is unavailing, however, because the record shows that different IL-15-specific inhibitors may operate in different ways that may result in differential effects, some of which may not include inhibition at all. See Ex. 1047 ¶¶21, 23, 40, 71; Ex. 1018, Abstr., 1576, 1579; Ex. 2013, 4:1– 8; Ex. 2014, 4:9–15; Ex. 2015 ¶ 22; Ex. 2025, 4:34–5:2; Ex. 1046, 166:21– 24, 168:25–169:5, 207:23–209:22, 210:4–17, 210:24–211:6; Ex. 1011, 1:67–2:4; Ex. 2005 ¶¶ 116, 134. Thus, we find that the record supports Drs. Abbas and Plott’s testimony, which we credit, that a person of ordinary skill in the art would be forced to hunt down and test every compound through painstaking Ex. 1002 ¶¶ 85–90, 92; Ex. 1047 ¶ 53 (Dr. Plott’s testimony that the “specification of the ’505 patent is essentially a black box (so far as which aspects of IL-15 signaling it inhibits and how it operates), leaving the reader to guess through trial and error which molecules might operate similarly to ChMBC7 and which do not.”); Ex. 1004 ¶ 61 (Dr. Plott’s testimony that “from the perspective of a clinician, the amount of experimentation required would be extremely burdensome and success would be speculative.”); Ex. 2007, 93:16–97:25, 38:208; Ex. 1046, 234:20–236:11. This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway. See Ex. 1047 ¶¶ 10, 53, 68; Ex. 2005 ¶ 71; Ex. 1046, 254:4–255:11, 158:12–160:20. The evidence has shown that IL-15/IL-15R inhibition is complicated and unpredictable, with some inhibitors also capable of enhancing forms of IL-15 signaling rather than preventing it. See Ex. 1047 ¶¶ 10, 25–26, 53; Ex. 2013, 2:10–18; Ex. 2014, 2:12–20; Ex. 2015 ¶ 3; Ex. 2025, 2:10–18; Ex. 2078, 267.” slip op. at 32

“patient is MSI-H after enrollment in a study in which pembrolizumab is to be administered is not within the scope of the claim step “in response to determining that the colorectal cancer is microsatellite instability high or DNA mismatch repair deficient, treating the patient with a therapeutically effective amount of pembrolizumab.” At this point in the proceeding, though, we do not interpret the claim step as meaning anything other than the treatment of colorectal cancer patients after they have been determined to be microsatellite instability high or DNA mismatch repair deficient. Although the term “in response to” in claim 1 requires that treatment of the patient occur after the determination that the colorectal cancer is MSI-H, we do not interpret the term to mean that other patients are not treated or that the recruitment and enrollment of patients for a clinical trial has any bearing on the steps recited in claim 1. We interpret a claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b) (2019). Under this standard, we construe 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.” Id. Patent Owner has not directed us to evidence that one of ordinary skill in the art would have understood treating a patient “in response to” the determination that the patient has a condition excludes treatment of other patients without the condition, although it does require that treatment of the patient occur after the determination that the colorectal cancer is MSI-H. The language of claim 1 refers only to patients that are determined to have microsatellite instability high or DNA mismatch repair deficient colorectal cancer, not to other patients. (See Ex. 1001, 25:40–50.) At this point in the proceeding, the record does not indicate that the treatment of patients determined not to be MSI-H is be factored into whether the teaching of treating patients determined to be MSI-H anticipates the method of claim 1. At this point in the proceeding, we construe the “in response to” limitation of claim 1 to mean that pembrolizumab is administered to a patient after the patient has been determined to be microsatellite instability high or DNA mismatch repair deficient, regardless of whether pembrolizumab is also administered to other patients.” slip op. at 17

“Furthermore, to the extent the MSI-H Study Record does not disclose the limitation of “in response to determining that the colorectal cancer is microsatellite instability high or DNA mismatch repair deficient, treating the patient with a therapeutically effective amount of pembrolizumab,” the record before us supports this limitation being rendered obvious by Pernot and the MSI-H Study Record. Specifically, because Pernot teaches that colorectal cancer patients are good candidates for immunotherapy, the evidence of the current record shows that one of ordinary skill in the art would have had a reason to use to PD-1 inhibitors to treat colorectal cancers. (See Ex. 1006, 3741.) Additionally, the focus in the MSI-H Study Record on a clinical study treating colorectal cancer patients who had been determined to be MSI-H with prembrolizumab indicates that it would have been obvious to test for this condition before treatment. The additional references discussed by Petitioner contribute further to a reasonable likelihood that Petitioner will prevail. For example, Libson reports the successful treatment of a colorectal cancer patient having MSI-H status with a PD- 1 inhibitor (see Ex. 1057, 463-64) and Champiat discusses evaluating the clinical activity of PD-1 agents in DNA mismatch repair, such as MSI+, colorectal cancer (see Ex. 1032, e27817-5).

“adopt Petitioner’s proposed definition of “capture probes” as encompassing at least, “PCR primer capture probes and solution-based hybridization capture probes (e.g., biotinylated oligonucleotide baits).” See DI 18–24. For the reasons set forth in our Institution Decision, and as further addressed below, we apply that definition here—albeit with a minor modification in wording. In particular, we credit Patent Owner’s argument that the phrase “PCR primer capture probe” is not a recognized term of art and its use in our construction “would improperly inject ambiguity into the claim.” POR 58– 59 (citing, e.g., Ex. 2018, 166:10–169:1, 171:16–175:2; Liquid Dynamics Corp. v.

Although we recognize Petitioner’s use of “PCR primer capture probe” as a shorthand for its position that, as read in light of the Specification, PCR primers are a species of, and/or indistinguishable from, the genus of capture probes, Patent Owner’s point is well taken. Accordingly, we clarify the meaning of “capture probes,” as used in the instant Specification, to encompass PCR primers and solution-based hybridization capture probes (e.g., biotinylated oligonucleotide baits).

“Ex2112, slide 5 for the ‘plurality of capture probes’ limitation of step 1(a),” Petitioner contends that its “bare reference to ‘pullout’” suggests at most, “that by May 2012, Mr. West contemplated that a particular type of capture probe would be among many other ‘lab solutions’ for addressing accuracy.” Reply 7–8; see Ex. 1225 ¶¶ 123–126. In this respect we note Mr. West’s testimony that he understood “pullout” in Slide 5, as a reference to Agilent SureSelect biotinylated probe system. See Ex. 1222, 83:8–85:22, 88:7–16. We, nevertheless, find persuasive Dr. Quackenbush’s testimony that “a POSA reviewing Slide 5 in light of the overall record on conception would have insufficient information to determine how, specifically, Personalis intended to use the ‘Pullout,’ other than that their purpose was to provide a laboratory solution to improve the accuracy of 2012 sequencing technology in some way.” Ex. 1225 ¶ 125. Considering the evidence of record, we credit Dr. Quackenbush’s testimony that a person of ordinary skill in the art reading Personalis’ conception exhibits, including Exhibit 2112, “would have found, at most, an incipient research project for improving the accuracy of sequencing technology that would involve the use of an undefined combination of various conventional techniques.” Ex. 1225 ¶ 128. In addition to Dr. Quackenbush’s testimony as to claim steps involving capture probes (elements 1(a)–1(c)), we further find persuasive his testimony that Patent Owner provides no corroboration of the conception of steps 1(d)–1(f), which require assaying samples obtained from the same individual obtained at different time points.

Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (quotation marks omitted). On its face, the preamble of claim 1 includes a “wherein” clause requiring that the biological sample be obtained “from a non-fetal source.” Because Petitioner does not explain how this limitation is either understood from the body of the claim, or severable from the remainder of the preamble, we do not find Petitioner’s argument persuasive. See Cochlear Bone Anchored Sols. AB v. Oticon Med. AB, 958 F.3d 1348, 1355 (Fed.

“Specification provides little guidance regarding how much of the genome must be sequenced under Patent Owner’s construction. See generally 00224 IPR, Paper 11 at 19–23. As discussed in detail on pages 15–16 of the Preliminary Response, however, the instant Specification does make a clear distinction between “untargeted sequencing (e.g., whole genome sequencing)” as compared to targeted sequencing approaches such as “whole exome sequencing,” or “deep sequencing over a fraction of the genome.” See e.g., Ex. 1001, 17:36–49, 25:64–34, 27:16–19, 43–46; cf. 00224 IPR, Paper 11 at 22 (“tak[ing] particular note of the [’394] Specification’s distinction between whole genome sequencing and targeted sequencing of the exome or other sub-genomic regions (e.g., Ex. 1001, 5:38–59, 24:35– 58), as well as the Specification’s acknowledgement that whole genome sequencing may encompass “low mean coverage regions” and “zero mean coverage regions,” (id. at 24:59–62, 28:33–42)”). As we read the Specification, the phrase “sequencing all or almost all of a genome,” speaks more tot the untargeted nature of the process rather than to an end result of the sequencing effort. In this respect, the instant Specification’s references to “high coverage whole genome sequencing,” “low coverage whole genome sequencing,” and “low” and “zero mean coverage regions from WGS,” indicate that whole genome sequencing does not mean that all or almost all of the nucleotide bases in a genome must be determined, but that “all or almost all” of the genome is available for sequencing.12 See e.g., id. at 25:64–67, 26:6–14, 27:16–19, 28:57–60; 32:37–45; see also 00224 IPR, Paper 11 at 19–23 (preliminarily determining that Leary disclosed whole genome sequencing despite evidence that the authors sequenced only about half of the genome). With the above explanation, we provisionally construe “whole genome sequencing as “a non-targeted approach to sequencing all or almost all of a genome.” We leave for later, and to the extent necessary, any 12 Consistent with Owner’s argument that “WGS has taken on many different flavors of meaning,” we presently understand the Specification’s recognition of “high” and “low” coverage whole genome sequencing as species of the generic term.

“We do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art. Although Petitioner did not expressly recite hematological malignancies, Petitioner did refer to expertise in clinical oncology, which would encompass the blood cancers recited in the claims. Neither party identifies a difference in the analysis or conclusions that would be based on differences in the ordinary skill in the art analysis.

“The parties do not identify any issue relating to the preamble that would impact our analysis. We recognize that Patent Owner is suggesting that Petitioner’s expert, at least, is reading the word “clinical” into the treatment language of claim 1. However, the plain language of the claim 1 preamble states “treating lymphoma or leukemia in a human patient” and is supported by a straightforward definition in the Specification of the ’087 patent, expressly limiting the invention to treatment of human patients. See Ex. 1001, 16:25–38. We therefore find that the preamble terms do not need claim construction because there is no actual dispute suggesting that, for example, claim 1 implicitly recites the term “clinical.” See, e.g., Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

“d. Analysis Considering the Wands factors as a whole, we find that the limited breadth of the claims, presence of several working examples, significant amount of direction and guidance provided by the ’087 patent, predictability in treating blood cancers with Bcl-2 inhibitors like GDC-0199, and high level of skill in the art are balanced against a large quantity of experimentation. Based on our consideration of the entirety of the evidence, we find that a preponderance of the evidence supports the conclusion that undue experimentation would not have been required to make and use the invention commensurate in scope with the claims of the ’087 patent. One underlying theme of Petitioner’s contentions and Petitioner’s expert testimony is the repeated contention that clinical trials were not completed by Patent Owner. See, e.g., Pet. 48 (“venetoclax (GDC-0199) was not FDA-approved”); Ex. 1020 ¶ 193. We find these arguments unpersuasive as we agree with Patent Owner that “[i]t is well established that a patent may be secured, and typically is secured, before the conclusion of clinical trials.” In re Montgomery, 67 F.3d 1375, 1382 (Fed. Cir. 2012). Particularly as to the dependent claims, a preponderance of the evidence of record does not support a finding that undue experimentation would have been required to administer three different doses of GDC-0199 starting with 100 mg, to use multiple daily dosing cycles of one day, to continue until disease progression occurs, or to combine with other treatment compounds.

“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.

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).

“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).

“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.
