ADAMS, Administrative Patent Judge. DECISION ON APPEAL This Appeal under 35 U.S.C. § 134(a) involves claims 1–22 (App. Br. 2). Examiner entered rejections under the written description and enablement provisions of 35 U.S.C. § 112(a). We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE and enter a New Ground of Rejection. 1 Appellant identifies “Rakesh N. Chettier and Michael R. Schramm” as the real party in interest (Appellant’s January 8, 2018 Appeal Brief (App. Br.) 2). Appeal 2018-004583 Application 15/421,186 2 STATEMENT OF THE CASE Appellant’s disclosure “relates to methods for use in preparing stem cell [(SC)] compositions and for use in administering such compositions to patients” (Spec. ¶ 2). Claim 1 is representative and reproduced below: 1. A treatment method comprising obtaining at least one SC from a patient determined to have or be predisposed to at least one genetic condition, identifying at least one marker associated with an increased risk of said condition in said at least one SC, editing the genetic sequence of said at least one SC via CRSP such that at least one of the following is performed comprising elimination of said condition increased risk associated marker from said at least one SC and introduction of a condition decreased risk associated marker to said at least one SC, causing said at least one SC to initiate differentiation into a predetermined tissue, administering said edited at least one SC to said patient. (App. Br. 32.) Grounds of rejection before this Panel for review: Claims 1–22 stand rejected under the written description and enablement provisions of 35 U.S.C. § 112(a). New Ground of Rejection: Claim 1 is rejected as indefinite under 35 U.S.C. § 112(b). ANALYSIS Appellant discloses that “[s]tem cells (SC) or compositions containing SCs . . . are known in the art . . . as are various methods of using such SCs, to treat a variety [of] conditions including genetic and non-genetic conditions in humans” (Spec. ¶ 3). In addition, Appellant discloses that Appeal 2018-004583 Application 15/421,186 3 “[m]ethods of editing genes and in particular, a gene editing method entitled the CRISPR Cas System (CRSP) is also known in the art” (id.). Appellant discloses: A first embodiment of the invention is a method of preparing an SC composition and administering the SC composition to a patient. The method preferably includes the following steps. A quantity of SCs is obtained from a donor. The SCs are genetically screen (e.g. genetically sequenced and analyzed). At least one marker associated with the existence or predisposition to at least one genetic condition is identified. The genetic sequence of the SCs is altered such that the SCs no longer include a marker associated with the existence or predisposition to at least one genetic condition. The SCs are administered to a patient. (Spec. ¶ 7 (emphasis added).) Thus, the first embodiment of Appellant’s invention, describes a method of preparing a SC composition and administering this composition to a patient, wherein: (a) [a] quantity of SCs is obtained from a donor, (b) [t]he SCs are genetically screen[ed], (c) [a]t least one marker associated with the existence or predisposition to at least one genetic condition is identified [in the SCs], (d) the SCs [are] altered such that the SCs no longer include a marker associated with the existence or predisposition to at least one genetic condition, [and] (e) [t]he SCs are administered to a patient. (See id. (lettering and emphasis added).) Appellant further discloses: A second embodiment of the invention is a method of preparing an SC composition and administering the SC composition to a patient. The method preferably includes the following steps. A patient is determined to be genetically predisposed to degenerative disk disease (DDD) or to have clinical indications Appeal 2018-004583 Application 15/421,186 4 of DDD or both. A quantity of SCs is obtained from the patient. The SCs are genetically screen (e.g. genetically sequenced and analyzed). At least one marker associated with the existence or predisposition to DDD (AKA an increased risk or so-called “causative” marker) is identified. The genetic sequence of the SCs is edited via CRSP such that the SCs no longer include a marker associated with the existence or predisposition to DDD and even more preferably such that the SCs come to include a marker associated with the absence or non-predisposition to DDD (AKA a decreased risk or so-called “protective” marker). The SCs are caused to initiate differentiation into the tissue of choice, namely disk tissue. The SCs are administered to the patient via injection into at least one disk of the patient. It is noted that because the SC administration is an autogeneic administration, the SCs have a very high likelihood of acceptance (i.e. will not be rejected by the patient's immune system) and yet the SCs will stimulate regeneration of disk material that is not predisposed to DDD. (Spec. ¶ 8 (emphasis added).) Thus, the second embodiment of Appellant’s invention, describes a method of preparing a SC composition and administering this composition to a patient, wherein: (a) a patient is determined to be genetically predisposed to degenerative disk disease (DDD) or to have clinical indications of DDD or both, (b) a quantity of SCs is obtained from the patient, (c) the SCs are genetically screen[ed] (e.g. genetically sequenced and analyzed), (d) at least one marker associated with the existence or predisposition to DDD (AKA an increased risk or so-called “causative” marker) is identified, (e) the genetic sequence of the SCs is edited via CRSP such that the SCs no longer include a marker associated with the existence or predisposition to DDD and even more preferably such that the SCs come to include a marker associated with the absence or non-predisposition to DDD (AKA a decreased risk or so-called “protective” marker), Appeal 2018-004583 Application 15/421,186 5 (f) the SCs are caused to initiate differentiation into the tissue of choice, namely disk tissue, and (g) the SCs are administered to the patient via injection into at least one disk of the patient. (See id. (lettering and emphasis added).) As Appellant makes clear, this second embodiment of Appellant’s invention describes an autogeneic administration of SCs and, therefore, these SCs have a very high likelihood of acceptance (i.e. will not be rejected by the patient's immune system). This second embodiment of Appellant’s invention encompasses a treatment of DDD, wherein the SCs will stimulate regeneration of disk material that is not predisposed to DDD (id.). In addition, Appellant discloses that although the second embodiment is described in relation to DDD, “a process substantially similar to the above may be used in administering SCs to address virtually any genetic condition” (id. ¶ 9). Appellant further discloses that “[t]he scope of the invention is . . . indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope” (id. ¶ 10). In a departure from the language in the Specification describing the embodiments of Appellant’s invention as “a method of preparing an SC composition and administering the SC composition to a patient,” Appellant’s claim 1 recites a treatment method (Spec. ¶¶ 7–8; cf. App. Br. 32). The treatment method of Appellant’s claim 1 comprises the following steps: (a) obtaining at least one SC from a patient determined to have or be predisposed to at least one genetic condition, (b) identifying at least one marker associated with an increased risk of said condition in said at least one SC, Appeal 2018-004583 Application 15/421,186 6 (c) editing the genetic sequence of said at least one SC via CRSP such that at least one of the following is performed comprising (i) elimination of said condition increased risk associated marker from said at least one SC and (ii) introduction of a condition decreased risk associated marker to said at least one SC, (d) causing said at least one SC to initiate differentiation into a predetermined tissue, [and] (e) administering said edited at least one SC to said patient. (See App. Br. 32 (Claims App’x) (lettering and emphasis added).) On this record, Examiner interprets Appellant’s claim 1 as an “ex-vivo method[] of cell gene therapy to treat a genetic condition in a patient with edited SCs via CRISPR” (Ans. 5). This interpretation is consistent with the second embodiment of Appellant’s invention (see Spec. ¶ 8). Thus, based on this interpretation of Appellant’s claim 1, Examiner pursues rejections under the written description and enablement provisions of 35 U.S.C. § 112(a). Appellant, however, insists that the treatment method of Appellant’s claim 1 “does not teach or claim the treatment of a genetic disease in a patient” (App. Br. 11), but rather “seeks prevention of a disease otherwise caused by a disease associated marker by eliminating the disease associated marker” (id. at 7). As Appellant explains, if a disease would otherwise have been developed due to the presence of an increased risk marker in an SC that is to be administered to a patient but that SC is edited pre- administration to eliminate such increased risk marker, the Appeal 2018-004583 Application 15/421,186 7 patient will not develop such disease due to the elimination of such increased risk marker. (App. Br. 11.) Stated differently, rather than interpreting Appellant’s claim 1 in the context of the second embodiment of Appellant’s claimed invention, Appellant insists that claim 1 must be interpreted in the context of the first embodiment of Appellant’s claimed invention, wherein if at least one marker associated with the existence or predisposition to at least one genetic condition is identified in donor SCs, the donor SCs are treated, or altered, such that the SCs no longer include a marker associated with the existence or predisposition to the at least one genetic condition, prior to administration to a patient, for whatever purpose (see Spec. ¶ 7). Thus, Appellant contends that Examiner’s rejections under 35 U.S.C. § 112(a) are based on an incorrect interpretation of Appellant’s claimed invention (see generally App. Br. 13 (“[t]he failure of the [E]xaminer to acknowledge that the claims do not claim the ‘treatment of a genetic condition in a patient’ is a fundamental flaw that runs throughout the [E]xaminer’s examination and has tainted the [E]xaminer’s decisions.”)). At this point, prior to addressing the merits of the rejections under 35 U.S.C. § 112(a), we must step back and determine whether the claims do, in fact, set out and circumscribe a particular area with a reasonable degree of precision and particularity. It is here where the definiteness of the language employed must be analyzed— not in a vacuum, but always in light of the teachings of the prior art and of the particular application disclosure as it would be interpreted by one possessing the ordinary level of skill in the pertinent art. In re Moore, 439 F.2d 1232, 1235 (CCPA 1971) (endnote omitted). It is only “having determined that the subject matter defined by the claims is particular and definite, [that] the analysis . . . turns to the first paragraph of Appeal 2018-004583 Application 15/421,186 8 section 112 to determine whether the scope of protection sought is supported and justified by the specification disclosure.” Id. The legal standard for indefiniteness under 35 U.S.C § 112(b) is whether a claim reasonably apprises those of skill in the art of its scope. See Amgen, Inc. v. Chugai Pharm. Co., 927 F.2d 1200, 1217 (Fed. Cir. 1991). On this record, it is clear that Appellant’s claim 1 does not meet this standard. To the contrary, for the reasons set forth above, and articulated by Examiner and Appellant, it is clear that Appellant’s claim 1 is amenable to various interpretations. Stated differently, Appellant’s claimed invention is indefinite. Ex Parte Miyazaki, 89 USPQ2d 1207, 1211 (BPAI 2008) (precedential) (“if a claim is amenable to two or more plausible claim constructions, the USPTO is justified in requiring the applicant to more precisely define the metes and bounds of the claimed invention by holding the claim unpatentable under 35 U.S.C. § 112, second paragraph, as indefinite.”). Thus, Appellant’s claim 1 is rejected under 35 U.S.C. § 112(b). Note, although we exercised our discretional authority under 37 C.F.R. § 41.50(b) to reject Appellant’s claim 1, we leave it to Examiner to determine the appropriateness of any further rejections of Appellant’s claimed subject matter. See Manual of Patenting Examining Procedure § 1213.02. 35 U.S.C. § 112(a): Because an analysis under 35 U.S.C. § 112(a) cannot proceed until the metes and bounds of that claims is determined under § 112(b), we pro forma reverse the rejections claims 1–22 under the written description and Appeal 2018-004583 Application 15/421,186 9 enablement provisions of 35 U.S.C. § 112(a). We emphasize, however, that our decision in this regard is based solely on the indefiniteness of the claimed subject matter, and does not reflect on the adequacy of the Specification to support the claimed subject matter. See Ex parte Miyazaki, 89 USPQ2d 1207, 1217-18 (BPAI 2008) (precedential) (prior art rejections of indefinite claims reversed by Board “pro forma” where claim interpretation required resort to “speculative assumptions as to the meaning of the claims”). TIME PERIOD FOR RESPONSE This Decision contains a new ground of rejection pursuant to 37 C.F.R. § 41.50(b) (effective September 13, 2004, 69 Fed. Reg. 49960 (August 12, 2004), 1286 Off. Gaz. Pat. Office 21 (September 7, 2004)). 37 C.F.R. § 41.50(b) provides “[a] new ground of rejection pursuant to this paragraph shall not be considered final for judicial review.” 37 C.F.R. § 41.50(b) also provides that the Appellant, WITHIN TWO MONTHS FROM THE DATE OF THE DECISION, must exercise one of the following two options with respect to the new ground of rejection to avoid termination of the appeal as to the rejected claims: (1) Reopen prosecution. Submit an appropriate amendment of the claims so rejected or new Evidence relating to the claims so rejected, or both, and have the matter reconsidered by the examiner, in which event the prosecution will be remanded to the examiner. . . . (2) Request rehearing. Request that the proceeding be reheard under § 41.52 by the Board upon the same Record. . . . Appeal 2018-004583 Application 15/421,186 10 No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
