    Claims 1–19 are unpatentable because the ’201 patent lacks written description support for the claimed genus of CRF1 receptor antagonists under § 112(a).

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateUnpatentable

      “[A] sufficient description of a genus instead 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. Id. at 1350 (citing Regents, 119 F.3d at 1568–69). Moreover, “an adequate written description requires a precise definition, such as by structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Id. (citing Regents, 119 F.3d at 1568 (quoting Fiers, 984 F.2d at 1171)). Furthermore, “functional claim language can meet the written description requirement when the art has established a correlation between structure and function.” Id. (citing Enzo Biochem, Inc. v. Gen-Probe Inc., 323 F.3d 956, 964 (Fed. Cir. 2002) (quoting 66 Fed. Reg. 1099 (Jan. 5, 2001))). “[M]erely drawing a fence around the outer limits of a purported genus is not an adequate substitute for describing a variety of materials constituting the genus and showing that one has invented a genus and not just a species.” Id.” slip op. at 42

      “According to Petitioner, a person of ordinary skill in the relevant art (“POSA”) “would have a medical degree or a Ph.D. in a field related to endocrinology, and would have knowledge of hormone regulation and disorders, as well as knowledge of the treatment regimens employed to treat such disorders . . . [and] would also have at least three years of experience conducting research concerning endocrine disorders, including CAH or other adrenal disorders.” Pet. 26–27 (citing Ex. 1005 ¶ 34 (Dr. Carey Declaration)). Patent Owner does not expressly contest this definition of a person of ordinary skill in the art in its Response. 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 ’201 patent itself, see, e.g., Exs. 1024, 1025, 2003, 2004, 2005, we apply Petitioner’s proposed level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (stating prior art itself can reflect the appropriate level of ordinary skill in the art). C.” slip op. at 22

      “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 an A4 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 ¶ 82. 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. See Ex. 1029, Abstr., 1065. Furthermore, despite Dr. Dobs’ testimony that “[t]he [prior art] references explain the typical CRF1 antagonist consists of a core nitrogen heterocycle with an aryl substituent adjacent to the core nitrogen atom and a branched alkyl group attached at the opposite end of the core,” Dr. Dobs also acknowledged that the “atypical CRF1 receptors depicted in Figures 11 and 12 of Williams had different structures, and lacked the nitrogen heterocyclic core.” Ex. 1042, 127:9–14, 130:13–131:16; see also Ex. 2014 ¶ 83. Additionally, Petitioner’s expert, Dr. Cutler, testified, by way of example, in his Reply Declaration that two of the ‘“first-generation CRF1 antagonists’ identified in Figure 1 of the Williams article do not fall within the Figure 2 structure Dr. Dobs relies upon.” Ex. 1047 ¶ 93.

At this point in the proceeding, we interpret 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.

Dr. Neugut’s testimony supports Petitioner’s argument that the cited teachings of Brown and Duval, as well as other references, would have motivated a person of ordinary skill in the art to obtain the results of the MSI-H Study Record. See Ex. 1003 ¶¶ 124, 130, 132, 136. Petitioner argues further that Brown and Duval would have motivated one of ordinary skill in the art to obtain the results of the MSI-H Study Record by treating patients with common types of MSI-H cancers, including endometrial, small bowel, and gastric cancers. Pet. 42–43 (citing Ex. 1003, ¶ 136). Petitioner argues further that the state of the art, as demonstrated by Brown and Duval, as well as other references, would have provided one of ordinary skill in the art with a reasonable expectation of success because physicians were actively treating patients with cancers that were known to be MSI-H with PD-1 inhibitors. Pet. 43 (citing Ex. 1016; Ex. 1017; Ex. 1003 ¶¶ 131–132). According to Petitioner, these other references would have “independently urged” those of ordinary skill in the art to treat MSI-H cancer with PD-1 inhibitors or other immunotherapy, such as pembrolizumab, and would have given them a reasonable expectation of success. Pet. 44–45. Petitioner cites, along with other references, Pernot, which states “[colorectal cancers] associated with MSI could lead to a more intense immune response, but also to specific immunoregulatory phenomena, making them good candidates for immunotherapy.” (Ex. 1006,3 3741; see Pet. 43.)

      “II. LEGAL STANDARD Pursuant to 37 C.F.R. § 42.71(d): A party dissatisfied with a decision may file a single request for rehearing without prior authorization from the Board. The burden of showing a decision should be modified lies with the party challenging the decision. The request must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply. When reconsidering a decision on institution, we review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion exists where a “decision [i]s based on an erroneous conclusion of law or clearly erroneous factual findings, or . . . a clear error of judgment.” PPG Indus. Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1567 (Fed. Cir. 1988). A rehearing request is not an opportunity for the requesting party to reargue its case or merely to express disagreement with the underlying decision.

      “Owner’s argument persuasive because Perkins discloses embodiments with “mutations at I182 among a group of 20 other possible locations for modifications,” 13 of which are mutations of specific amino acids that “can be changed to any of the 19 other natural amino acids.” Id. Perkins discloses further that modifications at each of those 20 possible sites can be combined such that “one, two, or more” of the mutations can be made together in other embodiments (Ex. 1006, 17–18), or in other words, “each species [is] combinable to create a vast number of species.” Dec. 35. In addition to the locations of modifications expressly listed in Perkins, Perkins adds yet another option in which “the mutated VSV-G envelope protein is as described in Nikolic et al.” (Ex. 1006, 18), which “describes the crystal structures of VSV G bound to its native LDL-R receptor” that RCSB PDB depicts in entries 5OY9 and 5OYL (Dec. 18). We also considered Dr. Rose’s testimony about the crystal structures depicted in RCSB PDB, namely that a person of ordinary skill in the art would have been motivated to modify Perkins based on the VSV-G crystal structures in the RCSB PDB. Perkins taught that mutations to VSV-G “inhibit binding of VSV-G to the low-density lipoprotein receptor (‘LDL-R’), while preserving the VSV-G protein’s fusogenic function,” and expressly disclosed making a mutation at I182. (See, e.g., Ex. 1005 at 19:29-20:2, 20:29-21:14, 21:16-27; Ex. 1006 at 16.) The VSV-G crystal structures in the RCSB PDB taught that I182 is nearby negatively charged amino acids on the LDL-R. Thus, a person of ordinary skill in the art would have been motivated to incorporate a mutation which negated an interaction with the negatively charged residues in the LDL-R. (Ex. 1005 at 19:29–20:2; Ex. 1006 at 16.) Dec. 37. discussed above, “Perkins provides a list of many mutations and combination[s] thereof, but provides no direction as to which of the many possible choices is likely to be successful.” Id. at 37–38. Thus, we were not persuaded that choosing an embodiment with a mutation at I182 from Perkins’s other listed embodiments with 20 possible locations for modifications, combinations of modifications at 20 possible locations, and the mutations described in Nikolic and depicted in RCSB PDB is an “easily traversed, small or finite number of alternatives that KSR suggested might support an inference of obviousness.” Id. at 35. In view of these findings, we noted that we did not “find sufficient evidentiary support for a determination that the navigation of RCSB PDB crystal structures to achieve the missing limitation would have been ‘evidently and indisputably within the common knowledge of those skilled in the art.’” Id. at 38.” slip op. at 6

      “not disclose the limitation of “in response to determining that the colorectal cancer is microsatellite instability high or DNA mismatch repair deficient, treating a human patient having colorectal cancer that is microsatellite instability high or DNA mismatch repair deficient 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. Ex. 1006, 3741; Ex. 1003 ¶ 136. 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 pembrolizumab 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 (Ex. 1057, 463-64) and Champiat discusses evaluating the clinical activity of PD-1 agents in DNA mismatch repair, such as MSI+, colorectal cancer (Ex. 1032, e27817-5). Pet. 44 (citing Ex. 1003 ¶ 49). Thus, based on the current record, we determine that Petitioner presents a reasonable likelihood that the method of claim 1 would have been considered obvious by one of ordinary skill in the art.

      “Petitioner argues that one of ordinary skill in the art relevant to the ’219 patent would have been a medical doctor or a professional in a related field with at least five years of experience with treating cancer. (See Pet. 11 (citing Neugut Decl., Ex. 1003 ¶19).) Petitioner argues further that the ordinarily skilled artisan would have experience in or access to a person with knowledge of clinical studies for therapeutics and how they work and to a pathologist with comparable experience. (See id.) Dr. Neugut’s testimony supports Petitioner’s arguments regarding the level of skill that an ordinarily skilled artisan in the relevant field would have. (See Ex. 1003 ¶ 19.) Accordingly, in the analysis below, and in the absence of argument by Patent Owner to the contrary, we apply the level of skill set forth by Petitioner and refer to Dr. Neugut’s testimony of what one of ordinary skill in the art would have understood at the time the application that became the ’491 patent was filed, which does not appear to be inconsistent with the level of skill reflected in the asserted prior art.” slip op. at 8

      “22. Our research group eventually approached Merck. Merck agreed in early 2013 to supply its then-unapproved anti-PD-1 antibody, MK-3475 (pembrolizumab) for use in the study. It was, however, the research team at Hopkins who secured IRB approval, conducted, and paid for the study. On June 12, 2013, the solicitation for patients was first posted on clinicaltrials.gov (Exhibit D). In my mind, the four arms allowed us to try to get at an answer to a question to which we did not know the answer-specifically whether or not patients with MSI-high or MMR deficient tumors would exhibit an improved response when treated with MK-3475, compared with the more common MSS [microsatellite stable] or MMR proficient colon cancers. Thus, the trial covered all patients with colon cancer, MSI and MSS, but separated into two groups. 23. The preliminary results of this study demonstrated clinical responses at an unexpectedly high rate (>50% objective response rate) in the MSI-high (MMR deficient) arm but not in the MSS (MMR proficient) arm. (Ex. 1002, 270–271.) This affidavit, submitted during prosecution of the ’974 patent, supports the argument that an improved outcome of treating a patient with a tumor exhibiting an MSI-high or a MMR deficiency status with pembrolizumab compared to similarly treating a patient without an MSI-high or a MMR deficiency status, a recited in claim 1, is an inherent result. Patent Owner does not dispute this result in the Preliminary Response. See Prelim. Resp. 7 (“The ’974 Patent reports that mismatch repair-deficient colorectal cancers (i.e., MSI-H CRC) had an immune-related objective response rate and immune-related progression-free survival rate of 40% and 78%, respectively—a huge improvement compared to the 0% and 11% rates found in mismatch repair-proficient colorectal cancers (i.e., MSI negative CRC).”).” slip op. at 17

In its Memorandum Opinion, the court acknowledged that inter partes reviews of additional patents involved in the litigation could be instituted. See Ex. 1101, 3. Accordingly, the first Fintiv factor weighs heavily in favor of not exercising discretion to deny institution of inter partes review. Because of the stay, the second and third Fintiv factors also weigh heavily in favor of not exercising discretion to deny institution of inter partes review. The stay indicates that the court’s trial date will not be close to the Board’s projected statutory deadline for a final written decision and that neither the court nor the parties will invest further in the parallel proceeding.
