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 .
Amended claims 18, 19, 24-28 are pending.
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. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
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.

Claim 18, 19, 24-28 provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 27-42 of copending Application No. 18712400 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because the conflicting claims contain overlapping subject matter, in genus-species fashion wherein the claims of ‘400 is the species with respect to the active ingredients.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
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 18, 19, 24-28 are rejected under 35 U.S.C. 112, first paragraph, because the specification, while being enabling for using few compounds of the recited formulae, does not reasonably provide enablement for plethora of conceivable active ingredients. For example, it is not seen where in the specification enabling disclosure is found for any peptide compound other than the 8 found at page 28 onto 29 (8 seq Id 1-8)
The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the invention commensurate in scope with these claims.
The determination that "undue experimentation" would have been needed to make and use the claimed invention is not a single, simple factual determination. Rather, it is a conclusion reached by weighing all the relevant factual considerations.
Enablement is considered in view of the Wands factors (MPEP 2164.01 (a)). These include: (1) breadth of the claims; (2) nature of the invention; (3) state of the prior art; (4) amount of direction provided by the inventor; (5) the level of predictability in the art; (6) the existence of working examples; (7) quantity of experimentation needed to make or use the invention based on the content of the disclosure; and (8) relative skill in the art.
All of the factors have been considered with regard to the claims, with the most relevant factors discussed below:
The active ingredients of the claims are drawn to peptides of 12 amino acids that also those containing substitutions with Lysine, Arginine and phenylalanine at different positions rendering the scope of the claims wide that finds little support in the specification. These 12 amino acids differ in acidity and basicity due to differing functionalities in their side chain and therefore are anticipated to impart different chemical and physical properties because of their presence or absence, for example with respect to their susceptibility to enzymatic cleavage or ability to penetrate cell membranes. With these substituents and hence the peptides are drawn to species that vary widely in physical and chemical properties such as size, molecular weight, , logP, acidity, basicity, etc. These factors are known in the art (see multiple references cited below) to greatly influence biological properties, for example, such as skin permeability.
There is no guidance on what to choose from these possibilities Enablement is a two prong (make and use) requirement. While making peptides are elementary in organic chemistry, the properties of the peptides made are anticipated to be predictable.
Biological properties are unpredictable and are ultimately tide to the chemical structure. See “Role of the Development Scientist in Compound Lead Selection and Optimization” by Venkatesh, J. Pharm. Sci. 89, 145-154 (2000) (p. 146, left column). Likewise, J. G. Cannon, Chapter Nineteen in Burger's Medicinal Chemistry and Drug Discovery, Fifth Edition, Volume I: Principles and Practice, Wiley-Interscience 1995, pp. 783-802, 784, teaches many caveats in analog design such as

The teachings of Venkatesh and Cannon are also consistent with applicant’s own disclosure at last paragraph of page 1. Also see, Patel, Scientific Reports volume 9, Article number: 6298 (2019) titled Cell-penetrating peptide sequence and modification dependent uptake and subcellular distribution. According to Patel, a thorough comparative investigation into the relative potential of different CPPs for intracellular delivery of protein cargos is missing (in the art). The wealth of available CPPs literature is characterized by significant experimental differences (e.g. cargo, CPP concentration, cell type, incubation time, etc.) thus, it is difficult to draw clear conclusions about the relative performance of different CPPs from these investigations.
There is a substantial gap between what is taught in the specification and what is being claimed. For these reasons, one skilled in the art would be faced with undue amount of research. The specification lacks disclosure sufficient to make and use the invention, in predictable manner, commensurate with the scope of the claims.
MPEP 2164.01(a) states, “A conclusion of Iack of enablement means that, based on the evidence regarding each of the above factors, the specification, at the time the application was filed, would not have taught one skilled in the art how to make and/or use the full scope of the claimed invention without undue experimentation. ln re Wright, 999 F.2d 1557,1562, 27 USPQ 2d 1510, 1513 (Fed. Cir. 1993).'' That conclusion is clearly justified here. Thus, undue experimentation would be required to make and use Applicants' invention.
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.
