      “Patent Owner asserts that Petitioner’s definition requiring a Ph.D. or a Master’s degree and several years of experience indicates higher than ordinary skill because by 2008 next generation sequencing was performed in laboratories according to published protocols and would have been accessible to experienced laboratory technicians and graduate students. (Prelim. Resp. 8.) Patent Owner proposes that, instead, the appropriate level of ordinary skill in the art was a Ph.D. in a field related to molecular biology, or a B.S. or M.S. degree with three to five years of experience working in a molecular biology lab. (See id.) On this preliminary record, having considered Dr. Metzker’s testimony and Patent Owner’s reasoning, we agree that one of ordinary skill in the art would have had experience with next generation sequencing, but are not persuaded that this would only be possible in the field of molecular biology. For the purposes of this Decision, we find a person of ordinary skill would have had a Ph.D. in the field of chemistry, molecular biology, or biochemistry or a B.S. or M.S. degree with three to five years of experience working in any of those fields. The person of ordinary skill would have had experience with next generation sequencing methods and a working knowledge of how those methods functioned. This definition of a person of ordinary skill is consistent with the skill level reflected in the disclosures of the ’357 patent and prior art. We further note that neither aspect of the dispute over the skill level affects our decision to institute review. C. Claim Construction” slip op. at 8

      “Petitioner argues that we should construe the claim term “adaptor” as “any oligonucleotide that is attached to the target sequence.” (See Pet. 9.) Petitioner cites the ’357 patent as referring to an “adaptor” as “an oligonucleotide sequence, the ligation of which to a target polynucleotide or a target polynucleotide strand of interest enables the generation of amplification-ready products of the target polynucleotide or the target polynucleotide strand of interest.” (Ex. 1002, 4:20-25; see Pet. 9–10.) According to Petitioner, this described function can be performed by any oligonucleotide. (See Pet. 10.) Petitioner also cites the Examiner’s reasoning during prosecution that “since any oligonucleotide can perform such function, any oligonucleotide is considered to anticipate this term.” (See Pet. 10 (citing Ex. 1013, 77).) Petitioner further cites the specification of the ’357 patent and claims of the ’241 patent, which is a continuation of the ’357 patent, in support of this construction. (See Pet. 9–10 (citing Ex. 1002, 9:43–46 (“appending the adaptor to the nucleic acid fragments generated by methods described herein can be achieved using a ligation reaction or a priming reaction.”) (emphasis omitted); Ex. 1001, claim 10).) Patent Owner does not dispute this construction at this stage, arguing only that the term need not be construed beyond its plain and ordinary meaning and reserving the right to propose constructions and identify terms needing construction later in the proceeding. (See Prelim. Resp. 9.) For the purposes of this decision, we adopt Petitioner’s construction of the term “adaptor,” although we note that it does not affect our decision to institute review. D.

      “The parties’ positions about the level of ordinary skill in the art are similar. (See Pet., 13–14; see PO Resp., 10–12.) In light of the parties’ arguments and evidence, we determine that the ordinarily skilled artisan would have had a bachelor of science degree in a relevant life sciences field, such as chemistry, biochemistry, or pharmacy, with at least three to four years of work or laboratory experience in pharmaceutical formulations and would have had access to team members having experience in pharmaceutical formulation and pharmaceutical regulatory approvals. (See Pet. 13–14; see PO Resp. 10–12; see Dec. 6–7.) Both of the parties’ proposals as to the level of ordinary skill in the art are consistent with the disclosure of the ’795 patent and the asserted prior art. The distinction between the parties’ proposals is minimal and would not change the outcome of this Decision. Thus, we adopt and apply Patent Owner’s proposal.” slip op. at 6

      “Although Petitioner puts forth constructions for terms in the claims of the ’795 patent, Patent Owner argues that we need not expressly construe any terms to resolve the controversy between the parties. (See Pet. 14–19; see PO Resp. 12.) Except as indicated below, we agree that express construction of the claim terms is not required because the parties do not materially dispute the meanings of the terms. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Limitation (c) of claim 1 recites “syrup formulation” once and then “syrup” by itself twice. The parties agree that two recitations of “syrup” by itself mean and are synonymous with “syrup formulation.” (See Tr. 15:16– 19 (counsel for Petitioner: “[T]he term, syrup, by itself, means the formulation. And for that reason, we--it’s our position that it’s the syrup formulation that has the specific viscosity requirements as well as the other features that we discussed.”); 31:17–20 (counsel for Patent Owner: “But those wherein clauses, what it’s referring to, the syrup formulation and the syrup -- it was all to a complete to a final formulation, right, it’s not just the agave syrup. Everybody here recognizes and understands that from that perspective.”).) Thus, the parties agree that the “viscosity of less than 1500 centipoise at about 22 degrees” limits the final “pharmaceutical syrup formulation for oral administration,” not the “agave syrup” limitation in limitation (b) of claim 1.” slip op. at 7

      “Patent Owner argues further that Dr. Crowley testifies that, “[g]enerally, suspensions having a viscosity in the range of 20 to 150 cP are considered readily pourable,” but that this range is well below the viscosity range of 200–900 cP taught in WO133 and the preferred viscosity range of 1000–3000 cP taught in the ’4666 patent. (See PO Resp. 45 (quoting Ex. 1003 ¶ 59).) Dr. Crowley testifies that “increasing the viscosity of a suspension formulation has been shown to impair the dissolution characteristics of immediate release acetaminophen” and that, “[w]ith respect to suspensions for oral administration, having a higher viscosity is generally not desirable.” (Ex. 1003 ¶ 59.) According to Patent Owner, this is a “teaching away” because Petitioner’s own expert testimony demonstrates a motivation not to combine the acetaminophen formulation of FR458- Example 1 with the 1000-3000 cP range of the ’4666 patent and the 200-900 cP range of WO133 since by his own admission doing so would yield bad results (i.e., impairing the dissolution characteristics of the acetaminophen) and generally undesirable higher viscosity. (PO Resp. 46 (citing Berkland Decl., Ex. 2009 ¶ 148).) Dr. Crowley’s cited testimony, however, is about general characteristics of suspensions for oral administration, whereas the WO133 refers specifically to sweetened analgesic formulations. (See Ex. 1006, 8:1– 3 (“The viscosity of the acetaminophen composition generally ranges from about 200–900 centipoise, preferably from about 300–700 centipoise.”); see Pet. Reply 8–9.) As Petitioner notes, Dr. Crowley also testifies that the viscosity of 29 commercially available, pediatric liquid oral antibiotic formulations were measured and determined to range from 20 to 1,780 cP” and that “[t]he viscosity of Children’s Tylenol has been reported to be less than 1,000 centipoise at shear rates between 0.05 and 0.2 reciprocal seconds.” (Ex. 1005 ¶ 58.) Thus, we are not persuaded that Dr. Crowley’s testimony contradicts the teachings regarding viscosity of analgesic formulations in the cited prior art.” slip op. at 23

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). (See Pet. 44.) Thus, based on the entire record before us, Petitioner presents a reasonable likelihood that the method of claim 1 would have been considered obvious by one of ordinary skill in the art.” slip op. at 23

      “B. Level of Skill Each party puts forth a characterization of the ordinarily skilled artisan in the field of the claims of the ’795 patent. (See Pet. 13 (citing Crowley Decl., Ex. 1003, ¶¶ 90–91); see Prelim. Resp. 3–4.) The parties’ proposed characterizations of the ordinarily skilled artisan are sufficiently similar that adoption of either would lead to the same result, institution. Thus, for the purposes of this Decision only, we adopt Patent Owner’s characterization of the ordinarily skilled artisan as having a bachelor of science degree in a relevant life sciences field, such as, chemistry, biochemistry, or pharmacy, with at least two years of work or laboratory experience in pharmaceutical formulations, and access to one or more team members having experience in pharmaceutical formulation and pharmaceutical regulatory approvals, or, in the alternative, at least three to four years of work or laboratory experience in pharmaceutical formulations, and access to one or more team members having experience in pharmaceutical formulation and pharmaceutical regulatory approvals. (See Prelim. Resp. 3–4.) We also note that the level of skill of an ordinarily skilled artisan is revealed by the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (holding that the absence of specific findings on the level of skill in the art does not give rise to reversible error “the prior art itself reflects an appropriate level and a need for testimony is not shown.” (quoting Litton Indus.

      “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art. In re Keller, 642 F.2d 413, 425 (CCPA 1981). Thus, at this point in the proceeding, Patent Owner’s argument is not persuasive because it does not address the teachings in the prior art that Petitioner asserts would render the formulations claimed in the ’795 patent obvious.” slip op. at 20

      “We are not persuaded by Patent Owner’s argument that the lack of specific residency/fellowship training or certification, disqualifies Dr. Vaux from providing opinion testimony on the motivations, understandings, and actions of those of ordinary skill in the art. Dr. Vaux testifies that he is “a medical doctor with specialty training in Pediatrics and Clinical Genetics” and is currently Professor and Clinical Chief of the Division of Medical Genetics in the Department of Medicine at UC San Diego. Ex. 1002 ¶ 1. He also testifies: Since 1994, I have regularly diagnosed and treated patients with urea cycle disorders (“UCD”), and continue to do so today. In treating UCD patients, I regularly prescribe nitrogen scavenging drugs and treat patients who are maintained on therapy with nitrogen scavenging drugs. Ex. 1002 ¶ 1. Thus, Dr. Vaux has actually treated UCD patients for at least five years (a requirement recited by Patent Owner, see PO Resp. 16), including prescribing drugs. Patent Owner does not direct us to evidence that Dr. Vaux’s testimony is untruthful or that his treatment of UCD patients is ineffective, indicating that he does not understand how to treat them. Accordingly, even if Dr. Vaux does not have the specialized certificates or particular training that Patent Owner argues are necessary, he has done the job for over twenty years of one who would carry out the claimed methods. We consider this experience more relevant than certificates or training. Thus, we determine that Dr. Vaux is qualified to provide opinions about the motivations, understandings, and actions of one of ordinary skill in the art.” slip op. at 15

      “In summary, the ’859 publication teaches that those of skill in the art would have known to use HPN-100 to treat subjects with UCDs. It also teaches that measuring plasma or blood level of ammonia was known to be useful in determining the effectiveness of a drug regimen for a particular patient and that measuring blood ammonia was a known step in adjusting drug dosages. The ’859 publication teaches that maintaining normal plasma ammonia levels was desirable in the art. Although specific measurements of 8 Patent Owner notes that the parties do not dispute the meaning of any of the claim terms. PO Resp. 2. Because the meaning of the terms in the challenged claims are evident from their ordinary meaning and not controversial, we need not provide a separate analysis of them. See Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“claim terms need only be construed ‘to the extent necessary to resolve the controversy.’ Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999).”). plasma ammonia do not necessarily indicate the upper limit of normal consistently across different ways of measuring it, the ’859 publication teaches that treatment would have been considered to be effective when plasma ammonia levels were less than what is determined to be the upper limit of normal in a given case. In addition to the ’859 publication, Petitioner relies on Blau and Simell for the teaching to collect blood from UCD patients after a fast in order to measure plasma ammonia levels. Ex. 1006 at 273 (Table 11.9); Ex. 1005 at 1118; see Pet. 25–26 (citing Ex. 1002 ¶¶ 58, 59); see also id. 1002 ¶ 46, n.2 (citing Ex. 1015 at S11). Anticipating Patent Owner’s argument that Blau relates to diagnosis not treatment of UCDs, Petitioner also cites to Exhibits 1010 and 1015 as evidence that it was generally recommended to measure plasma ammonia after a fast. See Pet. 16, n.2. Exhibit 1010 is a “Lab Update” about measurement in ammonia in blood, and Exhibit 1015 is a publication entitled “Measurement of ammonia in blood.” Both state that most methods recommend collecting a sample from patients who have fasted for at least 6 hours. See Ex. 1010, 4; Ex. 1015, 1. From this evidence, we agree with Petitioner that those of skill in the art would have known that measuring fasting serum ammonia levels, as taught in at least Simell and Blau, was known to be useful with the methods taught in the ’859 publication. In regard to Ground 2, which challenges claim 3 and the claims that depend on it, Petitioner cites Brusilow ’84 for its teaching of measuring a patient’s fasting plasma ammonia level when he or she is admitted, presumably to a hospital, and, in response to elevated levels, treating with the nitrogen scavenging drugs sodium benzoate and phenylacetate.

      “Petitioner may well be correct that preferring a non-anticholinergic does not necessarily exclude administering “another oral and/or topical therapy for reduction of sweating,” as required by challenged claim 4. Petitioner, however, does not point to any credible evidence or otherwise explain why an ordinary artisan would have chosen another therapy to reduce sweating to be administered in combination with glycopyrrolate. Without some articulated reasoning with rational underpinning as to why an ordinary artisan would have added a second therapeutic for reducing sweating to the transdermal patch of Bodor, which uses the anticholinergic to eliminate the formation of an aqueous layer between the delivery system and the skin to enhance the penetration of the transdermal drug being delivered, Petitioner has not met its burden of demonstrating that claim 4 20 would have been obvious over the combination of Bobrove and Bodor.

      “Bobrove specifically teaches applying a “roll on” glycopyrrolate solution. Ex. 1008, 6:26–27, 6:36–37. It, however, also generally teaches that glycopyrrolate is administered topically. Id. at 4:1. Thus, one of ordinary skill in the art would have had a reason to look for other means to apply glycopyrrolate. As Dr. Guy testifies, “[t]here are a limited number of ways to topically deliver a drug to a patient’s skin.” Ex. 1003 ¶ 16. In addition, Bobrove suggests to avoid the eyes, nose, and mouth during the topical administration. Ex. 1008, 5:37–39. Given these considerations, Bodor provides an effective alternative: a cotton cloth to absorb the drug and rub it on the skin. Ex. 1030, 15:39–54; see also Ex. 1003 ¶ 17 (explaining that, at the time of the invention, an ordinary artisan would have known that use of medicated pads “allowed for topical application of a solution, for example to a subject’s face, while excluding application to sensitive areas such as the eyes or mucous membranes”). Thus, we conclude Petitioner has shown, by a preponderance of the evidence, that an ordinary artisan would have had a reason to combine the teachings of Bobrove and Bodor.
