Office Action

§112 §DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Status Claims 1-22 are pending as filed 2/07/2023. Claims 16-22 are withdrawn as directed to a non-elected invention of Groups II or III. Claim 11 is withdrawn as directed to a non-elected species. Claims 1-10 and 12-15 are presently examined. Election/Restrictions Applicant’s election of Group I and the species of Example 55 in the reply filed on 12/29/2025 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.01(a)). The originally elected species of Example 55 (see Spec. filed 2/02/2023 at Table 1 on 82) is understood to be the compound corresponding to CAS NO: 2761348-53-0, which has the structure of Gua-Val-Hyp-IIe-Thr-Tyr-Pen-Asn-Arg-Dab-Thr-DDab-Lys-Cys-Dab-Arg-Tyr Wherein “Val” is at P1, and the amino group of P1 at the N-terminal is replaced with a guanidino group (Gua). The grey highlighted residues correspond to the residues limited by the proviso at claim 1. The originally elected species is understood to read upon claims 1-10 and 12-15 of Group I, but does not read upon claim 11. Following extensive search and examination, the originally elected species has been deemed free of the prior art. Per MPEP § 803.02(III) If the examiner determines that the elected species is allowable over the prior art, the examination of the Markush claim will be extended. If prior art is then found that anticipates or renders obvious the Markush claim with respect to a nonelected species, the Markush claim shall be rejected; claims to the nonelected species would still be held withdrawn from further consideration. The prior art search will not be extended unnecessarily to cover all nonelected species. Accordingly, Examination has been extended to the following species and structures: Example 1 (CAS NO: 2761347-99-1; claim 10); Example 2 (CAS NO: 2761348-00-7; claim 10); Example 3 (CAS NO: 2761348-01-8;

claim 10); Upon search and examination these species, which correspond to the exact structures shown at claim 10 and Example 1-138 as shown at Table 1 of the corresponding specification (see Spec. filed 2/02/2023 at Table 1 at pages 80-86)4. Accordingly, all explicitly disclosed and claimed species corresponding to Examples 1-138 have been fully considered and deemed free of the prior art. The closest prior art is FR2733237A1, which discloses CAS NO. 187281-84-1 (i.e., VPIIYCNRRTGKCQRM; which corresponds to instant claim 1 wherein P1 is Val, P2 is Pro, P3 is Ile, P4 is Ile, P5 is Tyr, P6 is Cys, P7 is Asn, P8 is Arg, P9 is Arg, P10 is Thr, P11 is Gly, P12 is Lys, P13 is Cys, P14 is Gln, P15 is Arg, and P16 is Met; wherein only P11 does not satisfy the requirements of the genus of instant claim 1 because P11 is limited to cationic D-amino acids). However, the pending claims have not been indicated as allowable at this time in view of remaining issues disclosed below. Examination has not proceeded beyond a proper Markush Grouping at this time. Claims 16-22 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 12/29/2025. Claims 11 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 12/29/2025. Claims 1-10 and 11-15 are presently examined. Priority Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) is acknowledged. Applicant has not complied with one or more conditions for receiving the benefit of an earlier filing date under 35 U.S.C. 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) as follows: The later-filed application must be an application for a patent for an invention which is also disclosed in the prior application (the parent or original nonprovisional application or provisional application). The disclosure of the invention in the parent application and in the later-filed application must be sufficient to comply with the requirements of 35 U.S.C. 112(a) or the first paragraph of pre-AIA 35 U.S.C. 112, except for the best mode requirement. See Transco Products, Inc. v. Performance Contracting, Inc., 38 F.3d 551, 32 USPQ2d 1077 (Fed. Cir. 1994). The disclosure of the prior-filed application, EP20020353.7 (filed 8/05/2020) fails to provide adequate support or enablement in the manner provided by 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph for one or more claims of this application. The MPEP states that "[w]hile there is no in haec verba requirment, . . . . claim limitations must be supported in the specification through express, implicit, or inherent disclosure." See MPEP § 2163. Lack of Express Support Claims 1 and 10 are representative of the pending claim scope. Neither claim literally appears in the disclosure of EP20020353.7. Accordingly, the priority document fails to provide literal support for the pending claim scope that is synonymous or equivalent in scope. Lack of Implicit or Inherent Support The MPEP states that "[w]hile there is no in haec verba requirment, . . . . claim limitations must be supported in the specification through express, implicit, or inherent disclosure." See MPEP § 2163. In the absence of express support, the relevant issue is whether or not the claimed invention is supported by Pro’231 through implicit or inherent disclosures. Here, EP20020353.7 notably only discloses Examples 1-72 (see, e.g., EP’353 at Table I; compare with instant Table 1; compare EP’353 at claim 1 at P2 with instant claim 1 at P2). Accordingly, EP’353 provides no literal, inherent, or implicit support for the species and structures of Examples 73-138 or the scope of the genus of claim 1 as instantly claimed. Accordingly, the priority document fails to provide implicit or inherent support for the pending claim scope that synonymous or equivalent in scope, or otherwise commensurate in scope with the pending claims. Conclusion Accordingly, priority to EP20020353.7 (filed 8/05/2020) is denied for all claims, which have been accorded a priority date of 8/05/2021, which corresponds to the filing date of PCT/EP2021/025301 (filed 8/05/2021). Information Disclosure Statement The IDS filed 6/21/2023; 7/17/2024; and 5/09/2025 are each acknowledged and presently considered. Claim Interpretation For purposes of examination, the claim scope has been interpreted as set forth below per the guidance set forth at MPEP § 2111. Claims 1 and 10 are representative of the pending claim scope. Applicable claim interpretation is set forth below. Claim Rejections Claim Rejections - 35 USC § 112(b) 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 10 and 13 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. Claim 10 recites the limitation "Ex138". There is insufficient antecedent basis for this limitation in the claim, as “Ex138” is not defined or explained. Claim 13 recites “especially in the form of….”, which is understood to be exemplary language, which renders the claim scope indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Accordingly, claims 10 and 13 are rejected as indefinite. Claim Rejections - 35 USC § 112(d) The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claims 15 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 15 depends from claim 1, both claims are directed to products, and dependent claim 15 only differs from claim 1 by recitation of an intended and expected use (i.e., any compound of claim 1, “for use as….”). This language does not further limit the structures or scope of instant claim 1. Accordingly, claim 15 is rejected under 35 USC 112(d) for failing to further limit the scope of the claim upon which it depends. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements. Claim 15 is rejected. Improper Markush Grouping Claims 1-9 are rejected on the basis that it contains an improper Markush grouping of alternatives. See In re Harnisch, 631 F.2d 716, 721-22 (CCPA 1980) and Ex parte Hozumi, 3 USPQ2d 1059, 1060 (Bd. Pat. App. & Int. 1984). A Markush grouping is proper if the alternatives defined by the Markush group (i.e., alternatives from which a selection is to be made in the context of a combination or process, or alternative chemical compounds as a whole) share a “single structural similarity” and a common use. A Markush grouping meets these requirements in two situations. First, a Markush grouping is proper if the alternatives are all members of the same recognized physical or chemical class or the same art-recognized class, and are disclosed in the specification or known in the art to be functionally equivalent and have a common use. Second, where a Markush grouping describes alternative chemical compounds, whether by words or chemical formulas, and the alternatives do not belong to a recognized class as set forth above, the members of the Markush grouping may be considered to share a “single structural similarity” and common use where the alternatives share both a substantial structural feature and a common use that flows from the substantial structural feature. See MPEP § 2117. The Markush grouping of instant claims 1-9 are improper because the alternatives defined by the Markush grouping do not share both a single structural similarity and a common use for the following reasons: The vast and highly varied genera and subgenera of claims 1-9 read upon and encompass numerous compounds lacking any common structural similarity (see, e.g., instant claims 1-2 and 4-5, noting that zero common structures are required to be present). Although dependent claims 3 and 6-9 recite narrower genera (claims 3 and 6-7 each require a P3 of Ile and P8 of Arg; and claims 8-9 each require a P3 of Ile, P5 of Tyr and P8 of Arg), these two or three defined positions do not reasonably define a “substantial structural feature that is essential to a common use” in view of the instant record (see, e.g., MPEP § 2117(II)). Furthermore, as peptidomimetics (see instant claim 1), the genus and subgenera of claims 1-9 are not limited to embodiments wherein “-” represents a normal peptide bond or embodiments having a normal peptide backbone; furthermore, as peptidomimetics that may include intramolecular bridges, the claim scope is not limited to linear embodiments. Accordingly, no common, consensus structure is recited and required at claims 1-9 that is essential to any common use, and therefore claims 1-9 are rejected as reciting improper Markush Groups. To overcome this rejection, Applicant may set forth each alternative (or grouping of patentably indistinct alternatives) within an improper Markush grouping in a series of independent or dependent claims and/or present convincing arguments that the group members recited in the alternative within a single claim in fact share a single structural similarity as well as a common use. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed.

A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.

[NSDP Rejection 01] Claims 1-9 and 12-15 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-9 and 11-17 of copending Application No. 18/294,227 (reference application; corresponding to US20240336654). Although the claims at issue are not identical, they are not patentably distinct from each other as explained below. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. MPEP § 804(II)(B)(2)-(3) identifies that a Nonstatutory Double Patenting Rejection may be appropriate based upon either an anticipation analysis or an obviousness analysis (see, e.g., MPEP § 804(II)(B)(2)-(3)). Instant claims 1-9 and 12-15 and copending claims 1-17 materially and substantially overlap in scope. For example, claim 1 of each copending claim set reads upon 16-mer peptidomimetic compounds having the general structure of P1P2P3P4P5P6P7P8P9P10P11P12P13P14P15P16 wherein P1 may be selected from an overlapping group including at least Ala, Gua-Val, Val, etc.; wherein P2 may be selected from an overlapping group including at least Hyp, Pro, etc.; wherein P3 may be selected from an overlapping group including at least Ala, Ile, Gly, etc.; wherein P4 may be selected from an overlapping group including at least Dab, Dap, etc.; wherein P5 may be selected from an overlapping group including at least Phe, His, Trp, Tyr, etc.; wherein P6 may be selected from an overlapping group including at least Dab, Dap, Asp, Glu, HgI, etc.; wherein P7 may be selected from an overlapping group including at least Ala, Abu, Ile, Asn, etc.; wherein P8 may be selected from an overlapping group including at least Dab, Dap, Lys, Arg, etc.; wherein P9 may be selected from an overlapping group including at least Agb, Dab, Cit, etc.; wherein P10 may be selected from an overlapping group including at least Cit, Thr, AlloThr, etc.; wherein P11 may be selected from an overlapping group including at least DLys, DOrn, DDab, etc.; wherein P12 may be selected from an overlapping group including at least Ala, Agb, Lys, etc.; wherein P13 may be selected from an overlapping group including at least Dab, Dap, etc.; wherein P14 may be selected from an overlapping group including at least Dap, Dab, Lys, etc.; wherein P15 may be selected from an overlapping group including at least Dap, Dab, etc.; and wherein P16 may be selected from an overlapping group including at least Ala, Phe, Tyr, etc.; Accordingly, the copending claim scopes are directed to overlapping subject matter, namely common peptidomimetics (compare instant claim 1 with App’227 at claim 1), and pharmaceutical formulations or medicaments comprising such peptidomimetics (compare instant claims 12-15 with App’227 at claims 12-17). In sum, under an anticipation analysis or obviousness analysis, instant claims 1 and 12-15 are not patentably distinct from copending claims 1 and 12-17 because the copending claims are directed to a materially and substantially overlapping genus of peptidomimetics. Regarding subgenera at instant claims 2-9: although the subgenera defined at dependent claims 2-9 of both Applications ostensibly differ at a single position (e.g., the subgenera at each claim 9 differs at P6), such differences cannot be said to patentably distinguish the pending claim scope in view of the guidance of each respective claim 1, which identifies functionally equivalent substitutions at that position, including one or more of the recited residues (e.g., at each claim 9, the claims reasonably inform artisans that Dap, Dab, and Asp could be utilized as functional equivalents at that position). In sum, the differences between the reference claims and instant claims appear to be minor because both claim sets recite substantially and materially overlapping genera and subgenera defining products for use for the same purpose5, and therefore the answer to the question “Is any invention claimed in the application anticipated by, or an obvious variation of, an invention claimed” in a patent or copending application6 is clearly “yes”. MPEP § 804(II)(B)(2)-(3) further identify that a Nonstatutory Double Patenting Rejection may be appropriate based upon either an anticipation analysis or an obviousness analysis (see, e.g., MPEP § 804(II)(B)(2)-(3)). Instant claims 1 and 12-15 are anticipated or otherwise rendered obvious in view of copending claims 1 and 12-17 because the claim scopes substantially overlap as discussed above, and an artisan would at once envisage the overlapping compounds (see, e.g., MPEP § 804(II)(B)(2)). Instant claims 2-9 are not patentably distinct from the copending claims under an obviousness analysis because instant claims 2-9 differ from copending claims 1-9 only in that the recited subgenera differ by one or fewer simple substitutions of equivalent amino acids, wherein such substitution would merely yield predictable and expected results, namely antimicrobial peptidomimetics, and wherein the equivalence at that position is explicitly taught by the claims as a whole of the copending application (see, e.g., MPEP §§ 2143(I)(B), 2144.06(II)). The reference claims are presumed to satisfy all statutory requirements in the absence of evidence to the contrary. Accordingly, claims 1-9 and 12-15 are provisionally rejected on the ground of nonstatutory double patenting. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. [NSDP Rejection 02] Claims 1-9 and 12-15 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-14 and 17-20 of copending Application No. 18019382 (reference application; corresponding to US20230295234). Although the claims at issue are not identical, they are not patentably distinct from each other as explained below. Regarding instant claims 1-9 and 12-15, generally, App’382 is directed to a subgenus of the instant claims that differ with respect to the instantly claimed compounds because US’234 claims peptidomimetics ranging in length from 17 to 19 residues in length, wherein the claimed sequences have a 1-3 residue N-terminal extension relative to the instantly claimed invention (compare instant claims with US’234 at claims). However, instant claims do not explicitly recite “consisting of” language or explicitly exclude embodiments having an N-terminal extension. Regarding instant claims 1-9, instant claim 1 is reasonably understood to encompass multiple overlapping species of copending claim 1, including peptidomimetic compounds comprising the structure of P1P2P3P4P5P6P7P8P9P10P11P12P13P14P15P16 wherein P1 may be selected from an overlapping group including at least Val, etc.; wherein P2 may be selected from an overlapping group including at least Hyp, etc.; wherein P3 may be selected from an overlapping group including at least Ile, etc.; wherein P4 may be selected from an overlapping group including at least Thr, etc.; wherein P5 may be selected from an overlapping group including at least Tyr, etc.; wherein P6 may be selected from an overlapping group including at least Pen, etc.; wherein P7 may be selected from an overlapping group including at least Asn, etc.; wherein P8 may be selected from an overlapping group including at least Arg, etc.; wherein P9 may be selected from an overlapping group including at least Dab, etc.; wherein P10 may be selected from an overlapping group including at least Thr, etc.; wherein P11 may be selected from an overlapping group including at least DDab, etc.; wherein P12 may be selected from an overlapping group including at least Lys, etc.; wherein P13 may be selected from an overlapping group including at least Cys, Dab, Dap, etc.; wherein P14 may be selected from an overlapping group including at least Dap, Dab, Lys, etc.; wherein P15 may be selected from an overlapping group including at least Arg, Dap, Dab, etc.; and wherein P16 may be selected from an overlapping group including at least Tyr, etc.; Accordingly, the copending claim scopes are directed to species within the scope of instant claim 1, that differ from explicitly recited claim scope only in that at least a one residue N-terminal extension is present (see App’382 at claim 1 at position X1, noting that t and s may each be zero; compare instant claims 1-9 with App’382 at claims 1-14). Regarding instant claims 12-15, App’382 also discloses that the recited peptidomimetics may be utilized in pharmaceutical formulations or medicaments (compare instant claims 12-15 with App’382 at claims 17-20). In sum, the differences between the reference claims and instant claims appear to be minor because both claim sets recite substantially and materially overlapping genera and subgenera defining products for use for the same purpose7, and the only ostensible difference is the presence of an additional N-terminal residue in the embodiments disclosed and claimed by App’382. However, the instant claims do not exclude N-terminal extensions, the additional N-terminal extension does not appear to impart any additional activity upon the embodiments of App’382, and the embodiments of App’382 satisfy the requirements of general formula (I) (compare instant claim 1 with App’382 at claims 1-14), or otherwise at most differ at a single position by the substitution of a functionally equivalent residue as taught at claim 1 (compare instant claims 1-9 with App’382 at claims 1-14). Therefore, the answer to the question “Is any invention claimed in the application anticipated by, or an obvious variation of, an invention claimed” in a patent or copending application8 is clearly “yes”. MPEP § 804(II)(B)(2)-(3) further identify that a Nonstatutory Double Patenting Rejection may be appropriate based upon either an anticipation analysis or an obviousness analysis (see, e.g., MPEP § 804(II)(B)(2)-(3)). Under an obviousness analysis, instant claims 1-9 and 12-15 are not patentably distinct from the copending claims under an obviousness analysis because the copending claims either fully encompass the instantly claimed peptidomimetics or otherwise differ by one simple substitutions of equivalent amino acids, wherein such substitution would merely yield predictable and expected results, namely antimicrobial peptidomimetics, and wherein the equivalence at that position is explicitly taught by the claims as a whole of the copending application (see, e.g., MPEP §§ 2143(I)(B), 2144.06(II)). The reference claims are presumed to satisfy all statutory requirements in the absence of evidence to the contrary. Accordingly, claims 1-9 and 12-15 are provisionally rejected on the ground of nonstatutory double patenting. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. [NSDP Rejection 03] Claims 1-9 and 12-15 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-5, 8-9, and 11-20 of copending Application No. 19/290,517 (reference application; corresponding to US20260042800). Although the claims at issue are not identical, they are not patentably distinct from each other as explained below. Regarding instant claims 1-9, instant claim 1 is reasonably understood to encompass multiple overlapping species of copending claims 1-5, including peptidomimetic compounds comprising the structure of P1P2P3P4P5P6P7P8P9P10P11P12P13P14P15P16 wherein P1 may be selected from an overlapping group including at least Gua-Val; wherein P2 may be selected from an overlapping group including at least Pro, or Hyp; wherein P3 may be selected from an overlapping group including at least Ile; wherein P4 may be selected from an overlapping group including at least Val(3OH); wherein P5 may be selected from an overlapping group including at least Tyr; wherein P6 may be selected from an overlapping group including at least Pen, Cys; wherein P7 may be selected from an overlapping group including at least Asn, Leu, Ile, Ser, Dap, His; wherein P8 may be selected from an overlapping group including at least Arg; wherein P9 may be selected from an overlapping group including at least Dab, Dab(iPr), Lys, Arg; wherein P10 may be selected from an overlapping group including at least Thr, Ser, etc.; wherein P11 may be selected from an overlapping group including at least DDab, DDab(iPr), DArg; wherein P12 may be selected from an overlapping group including at least Lys, Dab, Cit; wherein P13 may be selected from an overlapping group including at least Cys, Pen; wherein P14 may be selected from an overlapping group including at least Dab, Lys, Dab(iPr), Ser, Tyr; wherein P15 may be selected from an overlapping group including at least Arg, Dab, Orn, Orn(iPr), Ser, Thr; and wherein P16 may be selected from an overlapping group including at least Tyr, Nle, Cha; Accordingly, the copending claim scopes substantially and materially overlap by claiming overlapping genera and subgenera comprising identical species. Regarding instant claims 12-15, App’517 also claims that the recited peptidomimetics may be utilized in pharmaceutical formulations or medicaments (compare instant claims 12-15 with App’517 at claims 8-9 and 11-20). In sum, the differences between the reference claims and instant claims appear to be minor because both claim sets recite substantially and materially overlapping genera and subgenera defining products for use for the same purpose9, and therefore the answer to the question “Is any invention claimed in the application anticipated by, or an obvious variation of, an invention claimed” in a patent or copending application10 is clearly “yes”. MPEP § 804(II)(B)(2)-(3) further identify that a Nonstatutory Double Patenting Rejection may be appropriate based upon either an anticipation analysis or an obviousness analysis (see, e.g., MPEP § 804(II)(B)(2)-(3)). Here, under an anticipation analysis, instant claims 1-9 and 12-15 are rejected because the copending application claims the same compounds, having the same utility. Accordingly, claims 1-9 and 12-15 are provisionally rejected. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Allowable Subject Matter Claim 10 is objected to as being dependent upon a rejected base claim, but would currently be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Pertinent Prior Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Fehlbaum et al.11 discloses a 16-mer Thanatin variants comprising the sequence VPIIYCNRRTGKCQRM (see, e.g., Fehlbaum et al. at Fig. 1 on 1222, Table 1 at 1223 at “V16M”), which differs from the claim scope with respect to at least P5 and P11 as claimed Merlino12 discloses glycine replacement techniques for use in antimicrobial peptides (see, e.g., Merlino at title, abs). Merlino discloses that a glycine residue in an antimicrobial peptide may be mutated to DLys or other amino acid residues (see, e.g., Merlino at Table 1 on 751). Conclusion No claims are allowed. Claim 10 is objected. Any inquiry concerning this communication or earlier communications from the examiner should be directed to RANDALL L BEANE whose telephone number is (571)270-3457.
