“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

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 Preliminary Response.

RulingsFinal written decision- PTAB / AIA Trials › Motions to amend / substitute claimsMotion to amend granted in partGranted in part
“For the reasons discussed below, on the full trial record, we find that Patent Owner has not carried its burden of showing by a preponderance of the evidence that the proposed substitute claims introduce no new matter relative to the original disclosure. 35 U.S.C. § 326(d)(3); 37 C.F.R. § 42.221(d)(1); see also Paper 58, 2 (Patent Owner acknowledging that it “bears the burden to meet the regulatory and statutory requirements” for a motion to amend, including demonstrating that the substitute claims do not “introduce new matter”). Importantly, we note that Patent Owner fails to explain how the material cited in the claim chart supports the claims. See Mot. 15–16. Instead, Patent Owner provides only a claim chart with bare citations, leaving it to the panel to discern how the cited material supports the claim limitations. See id. Patent Owner’s failure to explain the citations constitutes a fatal error, as we have reviewed the passages cited by Patent Owner and are unable to discern where support is found for several of the substitute claim limitations. Where, as here, “the Board is unable to determine how the specification and drawings support the proposed substitute claims, the motion to amend may be denied.” Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019) (“TPG”),6 71.” slip op. at 15
- Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateUnpatentable
“Petitioner persuades us that the ’418 Application lacks adequate written description support for the formulation limitations of proposed substitute claim 18 [limitations 18a–8c]. As outlined by Petitioner and its declarants, the ’418 Application, including the Abstract, Field of the Invention, Summary of the Invention, and Detailed Description of the Invention sections, uniformly focuses on phosphate prodrugs of levodopa and carbidopa. See, e.g., Ex. 1004 (Sloan Decl.) ¶¶ 38–55, 64–69; Ex. 1003 (LeWitt Decl.) ¶¶ 89–97; Ex. 1047 (Forrest Decl.) ¶¶ 40–74, 80–92; Opp. 6– 10; Pet. 23–26, 49–55. We agree with Petitioner that “nothing in the specification suggests that the invention includes methods of subcutaneous infusion with anything other than the carbidopa prodrugs and L-dopa prodrugs of Formulas (I) and (II), respectively, or teaches how to get sufficient amounts of either L-dopa or carbidopa into solution, or achieve particular L-dopa plasma levels, without those particular prodrugs.” Pet. 27. Petitioner persuades us that the ’418 Application fails to contain “[so] much as a single generic sentence, anywhere in the application, suggesting the inventors possessed the claimed formulations.” Sur-reply 3. Additionally, the ’418 Application contains no example teaching administration of an aqueous formulation comprising carbidopa itself with levodopa itself or one of the three claimed levodopa prodrugs, let alone one that is suitable for continuous subcutaneous administration. See Ex. 1047 (Forrest Decl.) ¶¶ 61–72, 82–92. Patent Owner is correct that to establish written description support, neither “an actual reduction to practice,” nor a verbatim recitation of the claims is required. Sur-reply 4. Nevertheless, “[a]lthough examples are not always required to satisfy the written description requirement, the lack of any disclosure of examples may be considered when determining whether the claimed invention is adequately described.” Bos. Sci. Corp. v. Johnson & Johnson, 647 F.3d 1353, 1364 (Fed. Cir. 2011). Here, the lack of an actual reduction to practice or verbatim description of a formulation that falls within the scope of the claims is relevant, because we also see no other description or material in the ’418 Application that suggests the claimed methods extend to continuous subcutaneous administration of a composition comprising levodopa or one of the three claimed levodopa prodrugs, together with carbidopa, in an aqueous carrier.” slip op. at 28
- ExcludeMotion to exclude, deniedDenied
“All of the exhibits that are the subject of Patent Owner’s motion to exclude relate to the prior-art status and/or authenticity of Yacoby-Zeevi and ancillary related documents underlying Petitioner’s prior art-based challenges to the proposed substitute claims. See generally MTE. Because we deny Patent Owner’s request to enter proposed substitute claims 18–30 based on lack of written description support and do not reach Petitioner’s prior-art based challenges to the patentability of these claims, we do not rely on Exhibits 1005, 1007, 1040–1044, 1046, or 1048–1050 in this Decision. Accordingly we dismiss Patent Owner’s Motion to Exclude as moot.” slip op. at 49
- Strike new argumentNew argument consideredDenied
“On the other hand, Petitioner shows that Patent Owner took positions in its Motion to Amend that it only later sought to support with technical declarations. For example, in the Motion to Amend, Patent Owner elected to assert “that levodopa and carbidopa could be ‘interchanged’ in a formulation with their prodrugs, and that a skilled artisan could ‘perform a pharmacokinetic analysis to predict steady state levodopa plasma levels’ using the ‘parent compounds’ based on Example 24.” MTS 2 (citing Mot. 12–13). Patent Owner, however, “chose to forgo any expert support” on these issues at the time it filed its Motion to Amend, and instead waited until the Reply to submit technical declarations in support of these arguments. Id. We agree with Petitioner that although Patent Owner “was not required to anticipate the arguments that [Petitioner] would make in its Opposition” to the Motion to Amend, if Patent Owner “wanted to provide expert testimony to support the positions it actually took” in that Motion, “the TPG required [Patent Owner] to do so at that time, instead of waiting until [Petitioner] had limited ability to respond.” Id. at 5. Accordingly, we agree with Petitioner that in this respect at least some portions of Patent Owner’s Declarations are untimely, because it is “improper for a reply to present new evidence (including new expert testimony) that could have been presented in a prior filing.” TPG 74. Nevertheless, an order striking arguments and evidence in their entirety is an “exceptional remedy,” particularly under the circumstances here, where some portions of the Declarations are proper, while other portions are untimely. TPG 80. Moreover, “there is a strong public policy for making all information filed in an administrative proceeding available to the public.” Liberty Mut. Ins. Co. v. Progressive Cas. Ins. Co., CBM2012- 00010, Paper 59 at 40 (PTAB Feb. 24, 2014). Under the facts of this case, Patent Owner was permitted to file evidence to respond to Petitioner’s unpatentability claims, but also belatedly supported positions it made in earlier attorney argument. Petitioner’s Motion to Strike, however, challenges all of Patent Owner’s evidence, without acknowledging that some portions constitute proper reply. Although “[t]he Board is not required to attempt to sort proper from improper portions of the reply” (TPG 74, emphasis added), under the circumstances here, we agree with Patent Owner that Petitioner’s lack of specificity as to what it seeks to strike is fatal to Petitioner’s motion. Accordingly, we decline to strike the Declarations in their entirety as untimely.” slip op. at 46
