“Petitioner’s construction is reasonably based on remarks made during prosecution of the ’828 Patent by Applicant in Applicant’s December 3, 2003 Amendment. Pet. 9–10 (citing Ex. 1002, 277). In that Amendment, Applicant stated [e]xemplary structure or method steps corresponding to this claim feature is shown in Fig. 2A of the subject application, which illustrates a processor 157 which is “tightly coupled” to a memory. . . . Because the processor is “tightly coupled” to the memory, it will be virtually impossible for a user to supply false information to the memory by breaking the conductive trace or lead between the memory and the processor. This means, for example, that there is no possibility for altering the image before the authentication information is generated. Ex. 1002, 277. In discussing the difficulty “to supply false information to the memory by breaking the conductive trace or lead between the memory and the processor” (id.

“As explained in our Institution Decision, we adopted Patent Owner’s definition because we do not discern a substantive difference between the parties’ respective definitions for the level of ordinary skill in the art—both definitions provide for a highly skilled POSA with experience in formulating drugs. Dec. Inst. 8. Petitioner’s counsel confirmed during the hearing that there was no substantive difference between the parties’ definitions. Tr. 7:25–8:5. Accordingly, we find the parties’ respective definitions to be equivalent and consistent with the level of ordinary skill in the art as reflected by the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“When read as a whole, however, we find compelling that the Specification consistently identifies (Z)-endoxifen salts as separate from (Z)- endoxifen. Throughout the Specification—including in the Abstract and the Summary of the Invention—the ’334 Patent refers to “(Z)-endoxifen and salts thereof,” suggesting that references to “(Z)-endoxifen” alone do not include the salt forms unless expressly identified as such. See, e.g., id. at Abstract (“The present disclosure provides . . . methods of making (Z)- endoxifen or a salt thereof”), 2:60–62 (Summary of the Invention stating same); 6:4–6 (Summary of the Invention stating “process for manufacturing (Z)-endoxifen or salts thereof”). Moreover, the Specification states that although endoxifen is available commercially as an (E)/(Z) isomer free base mixture, as well as ≥98% (Z)- endoxifen HCL and (Z)-endoxifen citrate salts, “[t]here remains a need for (Z)-endoxifen free base preparations that are sufficiently stable for preparation of pharmaceutical compositions.” Id. at 82:3–5, 82:37–39. Accordingly, the Specification states, “[p]rovided herein in the present disclosure are preparations of endoxifen free base that are . . . at least 90% (Z)-endoxifen free base.” Id. at 82:43–45. Taking the language of the claims and the Specification as a whole, we determine that the intrinsic evidence supports construing the limitation “the compound of Formula (III) is (Z)-endoxifen” to be limited to the (Z)- endoxifen free base form and excludes the salt and solvate forms.” slip op. at 13

“presumption of enablement, and the patentee/applicant has the burden to prove nonenablement for such prior art”). As such, Apple instructs us that a petitioner need not provide evidence in its petition to show a prior art patent is enabling as part of its burden to prove anticipation. Id. at 449–50 (finding the Board erred in shifting the burden to the petitioner to provide evidence in its petition to show prior art patent publication was enabling). Thus, it is Patent Owner’s burden to establish by a preponderance of the evidence that Ahmad is not enabling. Before we turn to the substantive grounds, we must first resolve the parties’ disputes over several legal issues regarding enablement. First, Patent Owner asserts that “[w]hile the claims of a prior art patent are presumed enabled, . . . [t]here is no presumption that every prophetic example in the specification is enabled, especially where that prophetic example is not explicitly claimed.” PO Resp. 32 (citations omitted). This is an incorrect statement of the law. The Federal Circuit has clearly stated that “a presumption arises that both the claimed and unclaimed disclosures in a prior art patent are enabled.” Amgen Inc. v. Hoechst Marion Roussel, Inc., 314 F.3d 1313, 1354–55 (Fed. Cir. 2003). Patent Owner may rebut that presumption, but that presumption of enablement exists nonetheless for both the claimed and unclaimed disclosures.” slip op. at 17

“We find Petitioner has the better position. Ahmad itself provides the reason to combine Ahmad’s formulation with Cole’s enteric coating, stating in the stomach” and to “prevent release of medication before it reaches the small intestine.” Ex. 1003, 18:19–24. It was known that endoxifen could be susceptible to degradation in the acidic conditions of the stomach, and a POSA would have been motivated to use an enteric capsule to avoid acidic degradation and improve bioavailability. Ex. 1031 ¶ 6 (citing Ex. 1019, 1353). We credit Dr. McConville’s testimony that applying enteric coatings would have been routine (Ex. 1020 ¶ 71; Ex. 1031 ¶ 5), which is consistent with Ahmad’s disclosure that the enteric coating “can be done as methods known in the art.” Ex. 1003, 18:27–29. Similarly, the ’334 Patent states that “enteric tablets, enteric caplets, or enteric capsules of the present disclosure may be prepared by techniques known in the art.” Ex. 1001, 39:28–30. Moreover, the fact that Cole uses paracetamol as a model drug and not endoxifen is of no concern to our obviousness analysis. We credit the formulation expertise of Dr. McConville, who explains that “[i]n the case of an enteric coated capsule, it is the degradation of the enteric coating and the capsule that will control the release of the drug, not the nature of the drug itself.” Ex. 1031 ¶ 7 (citing Ex. 1008, 84). Thus, a POSA would have understood that the capsule in Cole would have the same benefits for use with other drugs, such as endoxifen. Id. Patent Owner and Dr. Davies identify certain complications that may plague enteric-coated endoxifen formulations and HPMC capsules, such as “potential interactions between enteric coatings and pharmaceutical compositions” and “variations in release profiles.” PO Resp. 63–64; Ex. 2020 ¶¶ 164, 166. But we are not persuaded by that argument, because we agree with Dr. McConville that Patent Owner and Dr. Davies fail to cite any credible evidence of such complications between enteric coatings and interactions. Ex. 1031 ¶¶ 8, 10. Having considered the arguments and evidence presented by the parties, we find that the combination of Ahmad and Cole teaches each limitation of claims 5–8, 16, and 17 and that a POSA would have had a reason to use the enteric coating and HPMC capsules of Cole with the (Z)- endoxifen formulation of Ahmad to reach the claimed invention with a reasonable expectation of success.

“More importantly, as shown in the above comparison, the underlying premise of Serendia’s arguments here and in the 383 IPR remains substantially the same. Thus, for the same reasons discussed in our decision instituting the 383 IPR, we find that EndyMed demonstrates a reasonable likelihood of prevailing with respect to at least one of challenged claims 13 and 14 of the ’774 patent. See 383 IPR, Paper 17, 11–18. That is not to say, however, that Serendia may not ultimately persuade us at trial of the deficiency of EndyMed’s showing based on a preponderance of the evidence.” slip op. at 10

“Here, there is no dispute that EndyMed’s petition is materially identical to the petition in the 383 IPR. Instead, Serendia argues that joinder should be denied due to EndyMed’s “unreasonable and unjustifiable delay” in filing the petition and seeking joinder with the 383 IPR, despite being aware of the ’774 patent and Jeisys’s petition for “more than 7 months” before filing. PO Opp. 1–2. We disagree. EndyMed need not justify its delay where, as here, EndyMed satisfies the joinder requirement of filing the petition within one month of our institution of trial in the 383 IPR. See 37 C.F.R. § 42.122(b); see also 37 C.F.R. §§ 1.7(a), 42.1(a). Indeed, per our rules, EndyMed could not have filed the instant petition prior to institution of the IPR it was seeking to join. See 37 C.F.R. § 42.122(b) (“Any request for joinder must be filed . . . no later than one month after the institution date of any inter partes review for which joinder is requested.” (emphasis added)). And, although there is a one-year statutory bar from the date of service of a complaint alleging infringement for requesting inter partes review, that bar does not apply to a request for joinder. See 35 U.S.C. § 315(b). Thus, despite being filed more than one year from the service date of Serendia’s complaint alleging infringement of the ’774 patent, EndyMed’s petition and motion are nonetheless timely.” slip op. at 12

“Serendia also argues that joinder should be denied due to duplicative efforts with the parallel Delaware litigation, which involves the same parties and patent as here. See PO Opp. 3–4. That argument fails for the simple reason that EndyMed submits a Sotera stipulation, agreeing not to pursue in the Delaware litigation the same grounds that are asserted in the petition here or any grounds that reasonably could have been raised here. See Pet. Reply 1–2. And because a Sotera stipulation mitigates concerns of duplicative efforts, we decline to discretionarily deny institution where a petitioner makes such a stipulation. See Katherine K. Vidal, Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (June 21, 2022) (“Director Memo”), at 3, 7–8. Thus, we will not discretionarily deny the petition or joinder on the basis of the parallel Delaware litigation.6 Also, to the extent Serendia contends EndyMed should not be permitted to join and continue an IPR that would otherwise be terminated due to Serendia’s settlement with Jeisys, we disagree for several reasons. First, this is EndyMed’s first (and only) petition challenging the ’774 patent. As such, there is no risk of “repeated attacks” by the “same petitioner,” as was the case in Apple Inc. v. Uniloc 2017 LLC, IPR2020-00854, Paper 9, 5– 13 (October 28, 2020) (precedential), where joinder was denied because the 6 To the extent Serendia also relies on duplicative efforts with the pending ITC investigation, the Director has expressly stated that the Board “will not” discretionarily deny a petition based on a parallel ITC proceeding.

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

“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.
