Office Action

§101 §112
DETAILED ACTION Acknowledgment and entry of the Amendment submitted on 10/10/25 is made. Claims 20, 21, 23, 24, 27 and 29-36 are currently under examination. Claims 37-41 remain withdrawn for being drawn to a non-elected invention. Rejections which are withdrawn: The Markush rejection and claim objections have been obviated by the amendment to the claims. The 112, first paragraph rejection regarding the Deposit Information has been satisfied in Applicants’ response. The following rejections are maintained and/or necessitated by the claim amendments: Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 20, 21, 23, 24, 27 and 29-36 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because it reads on a product of nature. The claimed bacterial strain is not markedly different from what naturally exists in nature. Even though isolation structurally changes a bacterium from its natural state, the resultant difference is no enough to render the isolated bacteria markedly different because the genetic structure and composition has not been altered. See Myriad, 133 S.Ct. at 2166-18. Claim 20 has been amended to recite: A bacterial strain identified using 16S rRNA Sanger sequencing standard methods as having at least 99.5% genetic homology to Weissella viridescens LB10G, which is deposited as DSM 32906, wherein the bacterial strain is capable of treating, alleviating, suppressing, prophylaxis, and/or preventing growth of a pathogenic micro-organism, wherein the bacterial strain is provided as one or more viable strains, one or more dead or inactivated strains, one or more strain lysates, one or more strain metabolites, or a combination thereof, or wherein the viable bacterial strain is provided in an encapsulated, microencapsulated, spray-dried, and/or lyophilized form. The position of the bolded “or” in amended claim 20 allows for the strain to merely include “one or more viable strains” since the wherein clause is optional. A mist or liquid (see claim 29) reads on water which would not be expected to alter the bacteria and could be used in any of the type of compositions recited in claim 29. Claim 30 does not include any structure to the compositions and a oral composition, etc., could be the bacteria in water which would not structurally change the bacterium from its natural state. Claim Rejections - 35 USC § 112-2nd paragraph The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 20, 21 and dependent claims thereof: 23, 24, 27, 29-36 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 20 and 21 are vague and indefinite because they recite a ‘genetic homology’ percent requirement to the LB10G strain, yet no nucleic acid sequence for the strain is recited in the claim making it impossible to determine the metes and bounds of the composition. While the specification can be used to provide definitive support, the claims are not read in a vacuum. Rather, the claim must be definite and complete in and of itself. Limitations from the specification will not be read into the claims. The claims as they stand are incomplete and fail to provide adequate structural properties to allow for one to identify what is being claimed. The amendment to include that the strain is identified “using 16S rRNA Sanger sequencing methods” does not remedy this rejection. Appropriate clarification and/or correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims are 20, 21, 23, 24, 27 and 29-36 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The instantly amended claims recite, for example: A bacterial strain identified using 16S rRNA Sanger sequencing standard methods as having at least 99.5% genetic homology to Weissella viridescens LB10G, which is deposited as DSM 32906, wherein the bacterial strain is capable of treating, alleviating, suppressing, prophylaxis, and/or preventing growth of a pathogenic micro-organism, wherein the bacterial strain is provided as one or more viable strains, one or more dead or inactivated strains, one or more strain lysates, one or more strain metabolites, or a combination thereof, or wherein the viable bacterial strain is provided in an encapsulated, microencapsulated, spray-dried, and/or lyophilized form. The instant specification does not provide sufficient written description for the scope of this claim. The specification only provides for the strain deposited as DSM 32906 and not any other variants, much less variants with the functional abilities recited in the instant claims, e.g., capable of treating, alleviating, suppressing, prophylaxis, and/or preventing growth of a pathogenic micro-organism. To fulfill the written description requirements set forth under 35 USC § 112, first paragraph, the specification must describe at least a substantial number of the members of the claimed genus, or alternatively describe a representative member of the claimed genus, which shares a particularly defining feature common to at least a substantial number of the members of the claimed genus, which would enable the skilled artisan to immediately recognize and distinguish its members from others, so as to reasonably convey to the skilled artisan that Applicant has possession the claimed invention. Applicants have not described the genus such that the specification might reasonably convey to the skilled artisan that Applicants had possession of the claimed invention at the time the application was filed. With the written description of a genus, however, merely drawing a fence around a perceived genus is not a description of the genus. One needs to show that one has truly invented the genus, i.e., that one has conceived and described sufficient representative species encompassing the breadth of the genus. Otherwise, one has only a research plan, leaving it to others to explore the unknown contours of the claimed genus. See Ariad, 598 F.3d at 1353 (The written description requirement guards against claims that "merely recite a description of the problem to be solved while claiming all solutions to it and . . . cover any compound later actually invented and determined to fall within the claim's functional boundaries."). Abbvie Deutschland GmbH & Co. v. Janssen Biotech, Inc., 759 F.3d 1285, 1300, 111 U.S.P.Q.2d 1780, 1790, 2014 BL 183329, 12 (Fed. Cir. 2014). To fulfill the written description requirements set forth under 35 USC § 112, first paragraph, the specification must describe at least a substantial number of the members of the claimed genus, or alternatively describe a representative member of the claimed genus, which shares a particularly defining feature common to at least a substantial number of the members of the claimed genus, which would enable the skilled artisan to immediately recognize and distinguish its members from others, so as to reasonably convey to the skilled artisan that Applicant has possession the claimed invention. Applicants have not described the genus of claimed fructanases such that the specification might reasonably convey to the skilled artisan that Applicants had possession of the claimed invention at the time the application was filed. The purpose of the "written description" requirement is broader than tomerely explain how to "make and use"; the applicant must convey with reasonableclarity to those skilled in the art that, as of the filing date sought, he or she was inpossession of the invention. The invention is, for purposes of the "writtendescription" inquiry, whatever is now claimed. See Vas-Cath, Inc. v. Mahurkar,935 F.2d 1555, 1563-64, 19 USPQ2d 1111, 1117 (Federal Circuit, 1991).Furthermore, the written description provision of 35 USC § 112 is severable fromits enablement provision; and adequate written description requires more than amere statement that it is part of the invention and reference to a potential methodfor isolating it. The nucleic acid [product] itself is required. See Fiers v. Revel, 25 USPQ2d 1601, 1606 (CAFC 1993) and Amgen Inc. V. Chugai Pharmaceutical Co. Ltd., 18 USPQ2d 1016. Possession may be shown in a variety of ways including description of an actual reduction to practice, or by showing the invention was 'ready for patenting' such as by disclosure of drawings or structural chemical formulas that show that the invention was complete, or by describing distinguishing identifying characteristics sufficient to show that the applicant was in possession of the claimed invention" (Id. at 1104). Moreover, because the claims encompass a genus of variant species, an adequate written description of the claimed invention must include sufficient description of at least a representative number of species by actual reduction to practice, reduction to drawings, or by disclosure of relevant, identifying characteristics sufficient to show that Applicant was in possession of the claimed genus. An objective standard for determining compliance with the written description requirement is, "does the description clearly allow persons of ordinary skill in the art to recognize that he or she invented what is claimed." In re Gosteli, 872 F.2d 1008, 1012, 10 USPQ2d 1614, 1618 (Fed. Cir. 1989). To satisfy the written description requirement, an applicant must convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention, and that the invention, in that context, is whatever is now claimed. Vas-Cath, Inc. v. Mahurkar, 935 F.2d 1555, 1563-64, 19 USPQ2d 1111, 1117 (Fed. Cir. 1991) and MPEP 2163.02. However, factual evidence of an actual reduction to practice has not been disclosed by Applicant in the specification; nor has Applicant shown the invention was "ready for patenting" by disclosure of drawings or structural chemical formulas that show that the invention was complete; nor has Applicant described distinguishing identifying characteristics sufficient to show that Applicant were in possession of the claimed invention at the time the application was filed. For inventions in an unpredictable art, adequate written description of a genus which embraces widely variant species cannot be achieved by disclosing only one species within the genus'" (Id. at 1106); accordingly, it follows that an adequate written description of a genus cannot be achieved in the absence of a disclosure of at least one species within the genus. The scope of the claim includes numerous structural variants, and the genus is highly variant because a significant number of structural differences between genus members is permitted. One of skill in the art would reasonably conclude that the disclosure fails to provide a representative number of species to describe the genus, and thus, that the applicant was not in possession of the claimed genus. The claimed subject matter is not supported by an adequate written description because a representative number of species has not been described. The scope of the claim includes numerous structural variants and the genus is highly variant because a significant number of structural differences between genus members is permitted and the Genus is highly variable in that strain of the same Genus/species often have different functional capabilities, see former prior art rejections and Applicants’ response of 10/10/25. The specification does not describe any members of the claimed genus by complete structure (with the exception of deposited strain DSM 32906; LB10G). One of skill in the art would reasonably conclude that the disclosure fails to provide a representative number of species to describe the genus, and thus, that the applicant was not in possession of the claimed genus. The claimed subject matter is not supported by an adequate written description because a representative number of species has not been described. There are no drawings or structural formulas disclosed of any of thesefragments or variants of the claimed polynucleotides. There is no teaching in thespecification regarding where the structure can be vary and still provide the functional capabilities recited in the instant claims. Based on the lack of knowledge and predictability in the art, those of ordinary skill in the art would not conclude that the applicant was in possession of the claimed genus of bacterial strains. Genentech Inc. v. Novo Nordisk A/S (CAFC) 42 USPQ2d 1001 clearly states: “Patent protection is granted in return for an enabling disclosure of an invention, not for vague intimations of general ideas that may or may not be workable. See Brenner v. Manson, 383 U.S. 519, 536, 148 USPQ 689, 696 (1966) (stating, in context of the utility requirement, that "a patent is not a hunting license. It is not a reward for the search, but compensation for its successful conclusion.") While every aspect of a generic claim certainly need not have been carried out by an inventor, or exemplified in the specification, reasonable detail must be provided in order to enable members of the public to understand and carry out the invention.” Applicant is referred to the revised guidelines concerning compliance with the written description requirement of U.S.C. 112, first paragraph, published in the Official Gazette and also available at www.uspto.gov Status of claims: No claims are presently allowed. Limiting the claims to the bacterial strain which is Weissella viridescens LB10G which is deposited as DSM 32906 would be allowable, provided the 101 and 112 rejections above are satisfied. Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
